Abstract

The invention relates to the technical field of plastic auxiliary agents, and particularly discloses a compound auxiliary agent for PVC processing and a preparation method thereof. The compound auxiliary agent for PVC processing is prepared from the following raw material components in parts by weight: 3-6 parts of a heat stabilizer, 4-8 parts of beta-(3,5-di-tert-butyl-4-hydroxyphenyl) propionicacid N-octadecanol ester, 2-4 parts of 2,5-methyl thiophene diformate, 1-2 parts of 5-amino-4-cyano-3-(2-ethoxy-2-oxoethyl)-2-thiophene ethyl formate, and 3-6 parts of a lubricant. The compound auxiliary agent for PVC processing is a completely new compound auxiliary agent, and has effects of heat resistance, weather resistance and lubrication.

Description

technical field [0001] The invention relates to the technical field of plastic additives, in particular to a composite additive for PVC processing and a preparation method thereof. Background technique [0002] PVC resin (polyvinylchloride) is one of the important organic synthetic materials; its products have good physical and chemical properties, and are widely used in industry, construction, agriculture, daily life, packaging, electric power, public utilities and other fields. However, the glass transition temperature of PVC resin is 77-90°C, and it begins to decompose at around 170°C. It has poor thermal stability. When it is above 100°C, it will decompose and produce hydrogen chloride; therefore, heat stabilizers must be added in the process of PVC resin processing. In addition, in order to improve the weather resistance of PVC, it is usually necessary to add weather resistance additives; after adding various additives, in order to further improve the processing perform...
