Problems solved by technology

But its weak point is that described heat-resistant PVC special-shaped material used material component is too many, and manufacturing process is complicated, and production cost is high, and the compatibility of thermosetting phenolic resin and thermoplastic polyvinyl chloride resin and chlorinated polyvinyl chloride resin is poor, It will lead to a decrease in its processing performance, thereby affecting the strength of the produced product
The entire process is cumbersome and complicated, and does not have the application value of industrial continuous production

Abstract

The invention relates to a formula for a high-heat-resistant plastic material. The plastic material is prepared from the following components, by weight: 60-80 parts of polyvinyl chloride resin; 20-40 parts of chlorinated polyvinyl chloride resin; 2.5-5 parts of a heat stabilizer; 1-10 parts of a heat resistant modifier; 5-10 parts of an impact resistant modifier; 1-6 parts of a processing auxiliary agent; 0.5-1.6 parts of a lubricant; 5-20 parts of a filler; 0.5-5 parts of a light stabilizer; 0.2-1 part of an anti-aging agent; and 0.01-0.03 part of a coloring agent. According to the invention, the plastic material has good molding performance, high dimensional stability and impact resistant strength, good heat resistance and weathering resistance, high corrosion resistance, and can meet requirements of long-term usage of a building industry.

Description

technical field [0001] The invention relates to a plastic profile, in particular to a formula of high heat-resistant plastic profile. Background technique [0002] Plastic profile is a mature environmental protection chemical product, the main component is PVC resin, including building doors and windows, exterior wall decorative panels, air-conditioning accessories, etc. It is one of the new materials that my country has focused on developing. Due to the poor heat resistance of PVC, it cannot be used at higher temperatures, which limits the application of PVC profiles to a certain extent. On the basis of plastic profiles, plastic steel profiles have been widely used in China in recent years, and metal materials (non-ferrous metals such as steel, aluminum, zinc, etc.) are added to the plastic cavity to enhance the firmness of the profiles. Due to its excellent physical properties such as rigidity, elasticity, and anti-aging properties, it has now begun to be popularized and ...
