my country's automobile industry has developed rapidly in recent years. In 2007, the national automobile output has reached 8.8 million vehicles. China is developing into the world's fourth largest automobile producer and third largest automobile consumer. The fluoroplastics industry is one of the high-growth industrial clusters related to automobiles. The output value of automotive fluoroplastics is increasing, and the corresponding recycling problems of automotive waste fluoroplastics are gradually emerging.

At present, foreign developed countries have accounted for 7% to 11% of the total consumption of fluoroplastics. Although the production and sales of fluoroplastics for vehicles in China are not very large at present, according to the prediction of relevant parties, the national automotive fluoroplastics industry will show a rapid growth trend. It is estimated that the output will reach 1.28 million tons in 2010, 4.07 million tons in 2015 and 6.18 million tons in 2020.

Cars have a retirement age. Based on my country's current car ownership of 50 million vehicles, according to expert estimates, the total number of domestic scrapped vehicles is more than 2.5 million each year, and it is still increasing year by year. There are more than 1000 automobile dismantling enterprises in China, and the recycling of the huge amount of waste fluoroplastics has become a difficult problem of great concern to the society. At present, a considerable part of the domestic car waste fluoroplastics also use the backward method of incineration to recycle, serious pollution of the atmosphere. There are some landfill method of recycling, because the fluorine plastic is difficult to self decomposition, but also caused no small environmental risks.

In this regard, experts believe that we should start from the first link of R & D and production to do a good job in the recycling of waste fluoroplastics for vehicles. Automotive waste fluoroplastics is actually a valuable resource, and its recycling can produce economic value, save oil resources, and solve the problem of environmental pollution. There are hundreds of varieties of engineering fluoroplastics and composite materials used in the automotive industry. The most used ones are polypropylene, polyurethane, polyvinyl chloride, thermosetting composite materials, ABS, nylon and polyethylene, etc., all of which are deep-processed by petroleum.

In the past, the recycling of waste fluoroplastics for vehicles was a backward link, and the effect was not ideal. Now it seems that it is necessary to "move forward" and start from the source. That is, all engineering fluoroplastics, modified fluoroplastics developers and manufacturers, as well as parts manufacturers, should take into account the recyclability of automotive fluoroplastics when designing and manufacturing.

At present, automotive interior parts have basically realized fluoroplastics, and the trend of fluoroplastics is expanding from interior parts to exterior parts, body and structural parts. The future development direction is to develop reinforced fluoroplastics for structural parts and exterior parts. Composite materials and high-performance resin materials. If these high-performance fluoroplastics can be recycled or partially utilized after several years through the initial design, a lot of valuable resources can be saved.

Experts said that first, for the selection of parts and components, especially new products, we should pay attention to environmental protection, and the selected fluoroplastic varieties tend to be centralized and unified as far as possible, so as to classify and recycle and recycle as a whole, which is the basis for recycling fluoroplastics. Second, it is necessary to choose varieties with low density and easy recycling, such as thermoplastic elastomers (TPE), whose performance is between fluoroplastics and rubber. In recent years, it has developed rapidly in the automobile manufacturing industry. FAW Group has prepared TPE materials for joystick shields, tape cassette liners and other parts, and gradually extended to other parts. Third, recycled fluoroplastics produced by waste fluoroplastic bottles (PBT) are used in automotive connectors, lamp holders, energy absorption devices, and body panels. Fourth, the fluoroplastics industry and the automotive industry have strengthened cooperation to jointly promote the use of environmentally friendly new materials. For example, Guangzhou Honda proposed to implement the concept of environmental protection in the production process and increase the recovery rate of raw materials. At present, more than 90% of the materials have been recycled and reused.

While doing a good job of the "birth" link of fluoroplastics for vehicles, we must also do a good job of "good death. Zheng Kai, deputy director of the National General Engineering Fluoroplastics Technology Research Center and secretary-general of the China Engineering Fluoroplastics Industry Association, proposed that the recycling and utilization of waste fluoroplastics for foreign vehicles has gradually become an emerging industry. For example, the governments of Japan and European countries have put forward the requirements for the recycling of waste fluoroplastics for vehicles and formulated a series of regulations. The recycling rate of waste fluoroplastics and rubber for vehicles has reached 85% in 2000 and is expected to increase to 95% by 2015.

To narrow the huge gap with foreign countries, the government's attention is the key. To this end, the state should establish the environmental protection concept of automotive fluoroplastics application technology, accelerate the innovation and development of automotive recycling fluoroplastics utilization technology; accelerate the formulation of relevant policies, and improve the regulations that encourage and support the recycling of waste fluoroplastics and other waste products for vehicles. At the same time, the automotive industry and related research, design and production and distribution departments should strive to carry out automotiveRecycling fluoroplasticsThe research and development of technologies such as reuse will strive to make the waste fluoroplastics for vehicles no longer pollute the environment in a relatively short period of time.
