Problems solved by technology

[0004] At present, recycled plastics are often made of a mixture of various waste plastics, and the performance of plastic products prepared from such recycled plastics is unstable. Therefore, it is necessary to modify the recycled plastics in the prior art to enhance their stability and restore plastics Its own characteristics and performance make it maintain the inherent characteristics of plastics

Abstract

The invention belongs to the field of plastics, in particular to a regenerated modified plastic particle. The plastic particle is characterized by comprising the following components in parts by mass:20-50 parts of waste plastic, 10-20 parts of straw powder, 10-20 parts of dried coconut shell powder, 5-10 parts of sawdust particles, 1-5 parts of a plasticizer, 1-5 parts of a compatibilizer, 1-5 parts of a stabilizer, 1-5 parts of an antioxidant, and 1-5 parts of a coupling agent. The waste plastic is modified with straw powder, coconut shell powder and sawdust particles, and the novel plasticparticle is prepared. The plastic particle has good toughness, high strength and strong corrosion resistance, the plastic particle is strong in stability, characteristics and properties of the plastic itself is reduced, and the plastic particle can keep inherent characteristics of the original plastic. Waste and old plastics are reused, social resources are saved, and the environment is protected.

Description

technical field [0001] The invention belongs to the field of plastics, in particular to a recycled modified plastic particle. Background technique [0002] As the consumption of plastic products continues to increase, waste plastics are also increasing. In addition, the annual consumption of plastics for automobiles in my country has reached 400,000 tons, and the annual consumption of plastics for electronic appliances and home appliances has reached more than 1 million tons. These products have become one of the important sources of waste plastics after they are scrapped. It is understood that in 2004, domestic waste plastics reached about 11 million tons. If the storage, transportation and processing of these waste plastics are not properly used and post-processed, the waste plastic raw materials waiting to be processed will definitely damage the environment and endanger the health of the people. [0003] With the rise of global crude oil prices, the price of plastic pro...
