全球塑料制品年产量超过2.2亿t,而其原料基本全部或部分来源于石化资源,随着石化资源的日益枯竭和白色污染的越演越烈,如何平衡工业应用与环境保护之间的关系成为当前塑料行业生存与发展的主要难题,而高填充技术的出现成为解决这一问题的可行途径。高填充技术主要采用少量塑料基体和大部分的廉价粉体制备出具有使用价值的复合材料,这种材料不仅可以节约大量的石化资源,同时粉体对生态环境也不构成任何威胁,具有很高的工业化应用价值。当前的高填充塑料有很多种,如不可降解塑料类的聚乙烯高填充材料、聚丙烯高填充材料,这类高填充塑料基本已经实现产业化应用;可生物降解塑料类如PBS高填充材料、PBAT高填充材料、PLA高填充材料等,这类高填充塑料基本还处于研究阶段,并逐步成熟,走向市场。
The global annual output of plastic products more than 220 million tons, and its basic raw materials, all or part of the source of petrochemical resources, with the depletion of petrochemical resources and white pollution intensified, how to balance the relationship between industrial applications and environmental protection become The current plastic industry survival and development of the main problems, and the emergence of high-filling technology has become a viable way to solve this problem. High filling technology mainly uses a small amount of plastic matrix and most of the cheap powder to prepare valuable composite materials, this material can not only save a lot of petrochemical resources, while powder does not pose any threat to the ecological environment, with high The value of industrialization. Currently, there are many kinds of high-filled plastics, such as non-degradable plastic high-filled polyethylene, polypropylene high-filled materials, such high-filled plastic basically has been industrialized applications; biodegradable plastics such as PBS high filling material, PBAT high filling materials, PLA high filling materials, such high-filled plastic basic is still in the research stage and gradually mature to the market.
