Abstract

A novel PVC heat stabilizer is characterized by at least comprising the following raw materials in parts by weight: 10 to 30 parts of organic zinc compound, 2 to 10 parts of organic tin compound, 20 to 40 parts of phthalic acid ester, 10 to 30 parts of alkyl acid ester, 10 to 30 parts of phosphite, 5 to 20 parts of chloromethoxyl fatty acid methyl ester, 1 to 5 parts of phenol, and 2 to 8 parts of 2-ethyl hexanol, wherein the organic tin compound comprises 1 to 4 sulfur atoms.

Description

technical field [0001] The invention relates to the field of plastics, in particular to a novel PVC heat stabilizer. Background technique [0002] PVC is the most widely used general-purpose plastic in the world. It is widely used in building materials, industrial products, daily necessities, floor leather, floor tiles, artificial leather, pipes, wires and cables, packaging films, bottles, foaming materials, sealing materials, fibers, etc. [0003] According to different application ranges, PVC can be divided into: general-purpose PVC resin, high-polymerization PVC resin, and cross-linked PVC resin. General-purpose PVC resin is formed by the polymerization of vinyl chloride monomer under the action of an initiator; high-polymerization PVC resin refers to the resin polymerized by adding a chain extender to the polymerization system of vinyl chloride monomer; cross-linked PVC resin is The resin is polymerized by adding a cross-linking agent containing diene and polyene to th...
