1. At home and abroad, China's engineering plastics industry started relatively late. Ten years ago, China's engineering plastics production capacity lags behind demand. More than 85% of raw material resins are imported, and more than half of the modified resin materials use foreign products. Nowadays, China's engineering plastics have achieved fruitful results, and a complete industrial chain with the ability to combine resin synthesis, plastics modification and alloys, and processing applications has gradually emerged. China's engineering plastics polymerization capacity has reached about 600,000 tons per year, and the annual output of modified resin materials is also more than 2 million tons. Even the special engineering plastics resins that were embargoed by foreign countries in the past are now almost all produced in China, and can be produced in small quantities. Export. In the past 10 years, the average annual output value of China's engineering plastics has increased by more than 20%. The scale of the company has continuously grown and the level of science and technology has increased. At present, in the engineering plastics synthesis, there have been large-scale companies such as China Blue Group, Yuntianhua Group, Shenma Group, Yizheng Chemical Fiber, and Deyang Technology. As engineering plastics have particularly excellent performance, their level of technological development has been taken seriously by the government, and has been listed as a key option for high-tech in the national long-term science and technology development program. In the Ministry of Science and Industry's industry support plan in 2009, seven engineering plastics projects including non-phosgene polycarbonates were included. In addition, after a long-term technical breakthrough, China's engineering plastics technology has developed rapidly. In terms of modified materials and resin alloys, some product technologies and quality indicators have also approached foreign advanced levels. Some of the special engineering plastic products process technology has entered the international advanced ranks.
Although China's engineering plastics have made considerable progress in the synthesis and processing, they have generally lagged behind developed countries. Compared with advanced countries, China's engineering plastics industry still suffers from shortcomings such as insufficient production capacity, poor product quality, small product specifications, lack of serialization, high performance products, small scale, dispersive production, and lack of large-scale leading companies. In addition, the state's support for the engineering plastics industry is still insufficient, making some product development slow, product recognition is still a certain gap with foreign countries, and international competitiveness is relatively weak. In addition, PA (nylon) and PC (polycarbonate), two industries favored by the industry, have experienced more and more concerns about the application of modified technology and future development direction after experiencing the financial crisis. Therefore, with the help of the ever-increasing industrial demand, we must comply with the current trend of low-carbon economy, grasp the opportunity of construction of a number of national key projects such as large aircraft, improve the level of science and technology, accelerate the upgrading of product structure, and promote the faster development of the engineering plastics industry in China. More healthy development.
Second, the development goals 1, to increase the synthetic production capacity of engineering plastics, to create core competitiveness, China's engineering plastics blending, many modified companies, but the relative lack of synthetic capabilities, under the strong support of the country, some domestic companies through the introduction of technology Or independently developed to achieve the industrial production of PA, PBT, POM, PPS, PC and other resins, and now has emerged such as Zhonglan Group, Yuntianhua Group, Shenma Group, Yizheng Chemical Fiber, Deyang Technology, Baling Petrochemical, etc. The pilot company that owns a large-scale synthetic device for engineering plastic resin production. Domestic scientific research institutes are also active. Among them, Jilin University has developed special engineering plastics, polyetheretherketone (PEEK), and established Changchun Jida High-tech Materials Co., Ltd. to realize the industrialization of PEEK and become the second company in the world to produce PEEK. Sichuan Huatuo Technology Co., Ltd. took the lead in industrializing polyphenylene sulfide (PPS) in China; Shanghai Synthetic Resins successfully developed polyimide (PI), and Ningbo Institute of Materials Technology and Engineering, Chinese Academy of Sciences also used thermoplastic polyamides. The structural design and advanced preparation method of the imine resin are breakthroughs. With the new catalyst additive technology and polymerization process, the thermoplastic polyimide resin with low cost, novel structure and excellent performance has been successfully developed, which has enabled our country to achieve in this field. Technological breakthroughs, but industrial transformation is still insufficient. During the twelfth five-year period, it should focus on the transfer and transformation of engineering plastics production technology, truly realize industrialization, and improve the international competitiveness of China's engineering plastic products.
2. To develop a new processing technology for engineering plastics to meet the application needs. Mixing and mixing, forming and post-processing are the general processes of polymer processing.
With the development of large-scale aircraft and automobile lightweight, the development of low-carbon economy in the world is becoming more and more popular. The traditional processing technology can no longer meet the new requirements of the development of engineering plastics applications, so it should be applied to the development of new types of processing Technology, such as: supercritical fluid assisted processing technology, including: supercritical foaming, extrusion, synthesis, degradation, and a series of related technologies; the development of new environmentally friendly materials processing technology, the current green environmental protection bio-based, bio-materials are One of the effective ways to ease the oil crisis, but the current domestic processing equipment can not meet the continuous production of plant fiber composite materials, greatly limiting the application process, it should pay attention to the development of new technologies; In order to achieve energy-saving emission reduction purposes, light Quantification is the focus of the automobile and other related industries. Therefore, the development of new low-cost fiber-reinforced resin matrix composites is a viable way to achieve its application. In addition, recycling of traditional engineering plastics is also the key to sustainable development. The development of engineering plastics applications is bound to produce more and more Waste, how green recycling, recycling is important to realize that we face a problem that must be addressed, should pay attention to the development of recycling technology during the second five, to resolve worries. Specialty resins are still the focus of attention.
3. Exploit the application of engineering plastics in emerging industries. The automobile manufacturing, industrial product manufacturing, electronic appliances and consumer product packaging industries are currently the four largest application areas of engineering plastics. Taking automotive as an example, the engineering plastics industry is no longer merely cater to the development of the auto industry, but it is more important for participants to play a more important role in the development of the auto industry. Lightweight, comfortable, and energy-saving are the latest trends in the development of automobiles. This trend will accelerate the progress of automotive plastics. When the vehicle's self-weight is reduced by 10%, the consumption of fuel can be reduced by 6% to 8%. The use of automotive plastics has become one of the indicators of a country's automotive production technology. At present, the average amount of plastic for each car in China is 100kg, which is still far from the international level of 150kg. The application of engineering plastics in emerging fields is the focus of development. Such as: new energy, advanced manufacturing, laser printing and so on. Such as: solar photovoltaic elements (PV) of various key materials, the current DuPont TedlarPVF (polyvinyl fluoride) film is already an integral component of the back sheet.
4. The development of general-purpose plastics and high-performance engineering plastics, high-performance, low-cost, and general-purpose plastic engineering have been the development goals of engineering plastics in recent years. This is also a summary of practice in the engineering plastics industry for more than 30 years. It is not only in line with China's actual situation, but also in line with world development trends. The use of new monomers to synthesize new plastic varieties is difficult, long-cycle, large-scale investment, and has a slow success. In the late 1980s, it has shown a decreasing trend. In the near future, there will not be too many new varieties available; instead, existing polymers And monomer through a special catalyst to change the structure, through the alloying, blending, modification and other technologies made of new varieties of materials to meet the different needs of the market. Making general-purpose plastic engineering, high-performance engineering plastics, and lower cost are the main goals for current and future development.
In short, through scientific and technological innovation, improving China's engineering plastics technology level, enhancing industry competitiveness, and promoting China's transition from a big plastics country to a plastics powerhouse is the constant goal of the development of engineering plastics.
Third, the measures suggest that China's engineering plastics industry has achieved considerable development in recent years, but there is still a large gap compared with foreign countries. This is mainly due to the fact that, on the one hand, R&D investment is insufficient, followed by R&D efforts. The combination is not tight enough, and it also involves many intermediate processes such as funding and transfer that require coordination between all parties. As a result, progress has been slow, and there have been relatively few projects for realizing industrialization. This situation can be improved from the following aspects: 1. Strengthen the closeness of production, education and research, and promote the transfer and transformation; 2. Focus on strength and breakthroughs; 3. Guide macroeconomic policies; 4. Appropriately use external forces to accelerate the industrialization process;
Fourth, the declaration of the project, 1. Supercritical fluids auxiliary processing technology, including: supercritical foaming, extrusion, synthesis, degradation and a series of related technologies; 2. Environmentally friendly materials processing technology: energy saving, saving materials and environmental protection for the The premise is to use physical and chemical means combined with equipment to improve the development of new environmentally friendly polymer materials; 3. Economic composite materials manufacturing technology: In order to achieve the purpose of energy saving and emission reduction, lightweighting is the focus of the automobile and other related industries, so the development of new Low-cost fiber-reinforced resin matrix composites are a feasible way to realize their applications. 4. Engineering plastics recycling technology: With the development of engineering plastics applications, it is bound to produce more and more waste. How to carry out green Recycling and realizing recycling are an important issue that we must solve. During the 12th Five-Year Plan, we should pay attention to the development of recycling technology and solve the worries of recovery.
5. Development of new fluororesin: To develop functional new fluorinated functional materials for applications such as water treatment and new energy. 6. Practical technologies for nanomaterials: Since the advent of nanotechnology, nanotechnology has not really exerted its advantages. In the future, research on nanomaterials is still an indispensable part, which may bring unexpected results to the development of the engineering plastics industry. 7. Functionalization and high-performance of engineering plastics: New types of materials are made by technologies such as alloying, blending, and modification, so that general-purpose plastic engineering and high-performance and low-cost engineering plastics can meet the different needs of the market.
