摘要（英）：

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.
