Problems solved by technology

[0002] General polyvinyl chloride plastics on the market have a small degree of branching, a relative density of about 1.4, a glass transition temperature of 77~90°C, and begin to decompose at about 170°C. They have poor stability to light and heat. Exposure to the sun will decompose and produce hydrogen chloride, and further autocatalyze the decomposition, causing discoloration and rapid decline in physical and mechanical properties

Abstract

The invention discloses a modified heat-resistant plastic which is prepared from a polyvinyl chloride resin, an acrylic resin, aluminum powder, modified glass fibers, calcium stearate, a dispersing agent, a heat stabilizer and a plasticizer. In order to overcome the defects in the prior art, a special method is adopted to modify the glass fibers, thereby enhancing the mechanical properties of the polyvinyl chloride plastic, improving the anti-friction and wear-resistant properties, and enhancing the weather resistance; the aluminum powder and calcium stearate subjected to high-temperature treatment are adopted to further enhance the heat resistance; and the production technique is simple and low in cost, and the prepared plastic has excellent heat stability.

Description

technical field [0001] The invention relates to the field of plastic production, in particular to a modified heat-resistant plastic. Background technique [0002] General polyvinyl chloride plastics on the market have a small degree of branching, a relative density of about 1.4, a glass transition temperature of 77~90°C, and begin to decompose at about 170°C. They have poor stability to light and heat. Exposure to the sun will decompose to produce hydrogen chloride, and further autocatalyze the decomposition, causing discoloration and rapid decline in physical and mechanical properties. Contents of the invention [0003] The purpose of the present invention is to provide a modified heat-resistant plastic, which is achieved through the following technical solutions: [0004] A modified heat-resistant plastic, the modified heat-resistant plastic is made of the following components in parts by weight: 45 parts of polyvinyl chloride resin, 32 parts of acrylic resin, 10 parts ...
