退役乘用车保险杠塑料同等性能再利用探索

Reuse with Equivalent Performance of Retired Bumper Plastic of Retired Passenger Vehicle

预计到2020年,我国乘用车报废量将达到800万辆,其中报废乘用车塑料量超过100万吨。目前,我国退役乘用车塑料回收利用处于起步阶段,行业管理混乱,回收技术落后,污染严重,且尚未实现回收乘用车塑料再利用价值最大化。因此,迫切需要深入研究乘用车塑料高附加值回收利用方式,推动该回收行业快速、健康发展,促进汽车工业可持续发展。文中以退役乘用车保险杠塑料为研究对象,通过研究得出其再生产相应汽车零部件同等性能回收利用技术方案,并依据该流程试制了含再生塑料的保险杠,并对含再生的保险杠进行了全面的分析研究。结果表明,含30%再生料保险杠的各项性能均满足生产要求。该研究为再生汽车塑料实现同等性能等高附加值再利用提供了借鉴。

With the rapid growth of passenger cars population, China＇s retired passenger vehicles population will exceed 8 million at the year of 2020; and it is estimated that the number of cars scrapped plastics will exceed 1 million tons. At present, the recycling industry of scrapped passenger cars plastics of our country is still in its initial stage, the scrapped plastic parts recycling technology lags behind developed countries. The confused industry management, backward recycling technology and serious pollution are the main features of the recycling industry. It is urgently needed to study the high value-added recycling technology of vehicle plastic, which is significant and beneficial for environmental protection, energy conservation and the sustainable development of the Chinese automotive plastic industry. In this paper, the retired passenger vehicle plastic bumper was selected as research object; the technical solution of recycled bumper reuse with equivalent performance was concluded. Then the new bumpers containing recycled plastics were produced according to the technical solution, and a comprehensive analysis of the produced bumper was proceeded. The results show that the performance of the bumper with 30 % recycled material meets the requirements of production..The study laid a foundation for the high value added recycling of others scrapped automobile plastic.
