Abstract

The invention relates to a formula of anti-tarnishing PVC plastic, and the anti-tarnishing PVC plastic comprises the following components in parts by weight: 60 parts of PVC resin, 3 parts of butadiene, 4 parts of alpha-vinyltoluene, 5 parts of maleic anhydride, 4 parts of steary methacrylate, 12 parts of trioctyl trimellitate, 2 parts of calcium stearate, 2 parts of zinc stearate, 7 parts of trimethylolpropane trimethacrylate, 5 parts of dicyclopentadiene dicarboxylic acid sodium salt, 6 parts of dicyclopentadiene dicarboxylic acid potassium salt and 5 parts of acetyl tributyl citrate acetate. The anti-tarnishing PVC plastic has the beneficial effects that the anti-tarnishing PVC plastic does not easily change color in the sun, can persistently keep the original color, and does not easily become fragile; the production efficiency is greatly improved; resources are saved; the cost is reduced; and the anti-tarnishing PVC plastic is abundant in raw material source, free of dust in the molding process, non-toxic and environment-friendly.

Description

technical field [0001] The invention relates to a chemical product, in particular to an anti-discoloration PVC plastic formula. Background technique [0002] PVC (polyvinyl chloride) is a chlorine polymer of PE (polyethylene). It is one of the most widely used plastics and is still used in large quantities. Its consumption is second only to polyethylene and polypropylene. There are many forms of PVC products, which can be divided into three categories: hard PVC, soft PVC, and PVC paste. In recent years, PVC plastic doors and windows have been widely popularized and applied in China. Since the molecular bonds of PVC contain chlorine elements that are easy to age and decompose, aging, discoloration, and deformation are prone to occur under long-term storage conditions. Therefore, it is meaningful to develop a composition with excellent performance, good impact resistance, anti-aging performance and low cost.
