Persistent plastic

Abstract

The invention relates to an organic polymer composite material, in particular to persistent plastic. The persistent plastic comprises the following components in percentage by weight: 83-95.8 percent of polyformaldehyde, 2-8 percent of hardening agent, 0.5-10 percent of toughener, 1-4.8 percent of antioxidant, 0.1-3.9 percent of plasticizer, 0.5-3.8 percent of foaming agent, 0.5-6.2 percent of stearate, 0.1-2.5 percent of other assistants and 0.5-5.5 percent of activate carbon. According to the persistent plastic disclosed by the invention, several agents in a certain proportion are added, so that the stability of the polyformaldehyde becomes stronger in the processing process of the polyformaldehyde; and the phenomenon that the polyformaldehyde is decomposed by heating at high temperature for an intermediate and long time is avoided and the polyformaldehyde is more stable.

Description

technical field [0001] The invention relates to an organic polymer composite material, more specifically, relates to a kind of plastic which is not easy to decompose. Background technique [0002] After long-term struggle and opening up to the world, China's plastics industry has formed a relatively complete industrial system and has become a basic material industry that keeps pace with steel, cement, and wood. As a new type of material, its application fields have far exceeded the above three. Since the entry of this material into the 21st century, China's plastics industry has made remarkable achievements and achieved a historic leap. As one of the pillar industries of the light industry, the plastics industry has maintained a growth rate of more than 10% in recent years. While maintaining a relatively fast development speed, the economic benefits have also improved. The total output value of enterprises above designated size in the plastic products industry ranks third a...

Problems solved by technology

[0004] Some of the plastics used in the market at this stage are made of polyoxymethylene as a raw material. Although polyoxymethylene is a tough and elastic material, it still has good creep resistance, geometric stability and impact resistance even at low temperatures. characteristics, but after long-term use, there are some common problems. If the processing time is long, it is easy to decompose under high temperature, which has a serious impact on industrial production.
