Problems solved by technology

[0003] In the production process of existing plastic materials, polyethylene or polypropylene is mainly heated by various organic solvents and then melted, and then made by hot pressing molding technology. These two materials, polyethylene or polypropylene, are non-toxic and tasteless, and are Human body safety performance is high, but polyethylene and polypropylene are poor in high temperature resistance. When exposed to high temperature, toxic substances will be precipitated from the material, which will deepen the degree of pollution and be more harmful, which is not conducive to the health of users. security risks

Description

technical field [0001] The invention relates to the technical field of plastic material production and processing, in particular to a high-temperature-resistant plastic material and a preparation method thereof. Background technique [0002] Plastic is a high molecular compound polymerized by addition polymerization or polycondensation reaction with monomer as raw material. It is commonly known as plastic or resin. It can freely change its composition and shape. , Colorants and other additives. The main component of plastic is resin. The term resin was originally named after the lipids secreted by animals and plants, such as rosin, shellac, etc. Resin refers to a polymer compound that has not been mixed with various additives. Resin accounts for about 40-100% of the total weight of the plastic. Plastic materials are widely used in people's daily life and work, and provide convenience for people's life and work. They are welcomed by people and have a wide range of applicat...
