Plastic material prepared by using waste thermosetting foam plastics and preparation method thereof

Abstract

The invention discloses a plastic material prepared by waste thermosetting foam plastics and a preparation method thereof. The plastic material is prepared by uniformly stirring the following raw materials, wherein the raw materials comprise the following components in parts by mass: 50-80 parts of waste thermosetting foam plastic powder, 0-20 parts of recycled rubber powder, 0-10 parts of solid ethoxyline resin powder, 5-10 parts of plasticizing agent, 2-5 parts of flame retardant agent, 0-3 parts of pigment, 0-1 parts of curing agent, 0.5-1 part of silane coupling agent, 0.5-1 part of antioxidant 1010 and 0.2-1 part of aging resistant agent GW-540. The compression plastic material prepared by the formed materials solves the problem of recycling difficultly regenerated waste thermosetting foam plastic powder and can be made into various plates in a hot-press way without adhesive, and a product has favorable performance and the characteristics of safety, environmental protection, water prevention and flame resistance.

Description

technical field [0001] The invention relates to a plastic material and a preparation method thereof, more specifically, to a plastic material prepared from waste thermosetting foam plastics and a preparation method thereof. Background technique [0002] The rapid development of the manufacturing industry and the automobile industry has brought convenience to people's lives, but it has also brought a large amount of thermosetting foam plastic waste, which has caused great pressure on the ecological environment. How to improve the comprehensive recycling efficiency of plastic products and the quality of recycled products, reduce plastic solid waste and control environmental pollution in the recycling process has become a worldwide issue. At present, China's recycling and reuse of waste plastics is not ideal. Most of them are simply used, with low technical level and lack of market competitiveness. ", the application date is March 28, 2000, the application number is 00113344.6...

[0003] According to the above patents, most waste plastics are used to make composite materials such as plastic wood and produce lubricating oil, gasoline, diesel oil, heat shrinkable materials, etc. after thermal cracking. The preparation method is complicated, the technical level is low, the energy consumption is large, and it is easy to cause secondary waste. secondary pollution

At present, the recycling status of thermosetting foam plastic waste in my country is not ideal. Most of them only develop and utilize thermoplastic foam plastics that are easy to regenerate, and there is a lack of recycling methods for thermosetting foam plastics that are difficult to regenerate.
