Abstract

The invention relates to the technical field of preparation of heat stabilizers, in particular to an environment-friendly powder heat stabilizer for slush molding products. The heat stabilizer is prepared from the following components in parts by weight: 15-25 parts of powdery zinc stearate, 10-20 parts of calcium stearate, 15-25 parts of an acid acceptor, 1-5 parts of an antioxidant, 5-10 parts of an auxiliary stabilizer, 5-10 parts of a coupling agent and 10-20 parts of a filling agent. Compared with a traditional liquid stabilizer, the powder stabilizer for PVC slush molding has the advantages that introduction of solvent oil with strong volatility is avoided by preferably selecting a powder material, generation of volatile odor is greatly reduced, and compared with the traditional liquid stabilizer, the powder stabilizer for PVC slush molding has the advantages that the compatibility is equivalent to that of PVC paste resin and a plasticizer, influence on colloid viscosity is small, and the heat resistance of the prepared powder stabilizer for PVC slush molding is greatly improved by scientifically proportioning the material proportion.

Description

technical field [0001] The invention relates to the technical field of heat stabilizer preparation, in particular to a powder environment-friendly heat stabilizer for slush-molded products. Background technique [0002] The slush molding process can produce car dashboards, toy dolls, toy balls, shoe soles, etc. Because these products are in direct contact with people, higher requirements are put forward for their environmental protection. In recent years, with the increasing calls for environmental protection, people have become increasingly strict about the hygienic performance of plastic products. As PVC products that are in direct contact with humans, non-toxic and tasteless has become a new trend in its development. [0003] Liquid stabilizers are used in the processing of traditional PVC slush products. The liquid stabilizers have good compatibility with plasticizers and paste resins, are easy to disperse, and are conducive to the formation of uniform colloids. At pres...
