Calcium-zinc heat stabilizing agent for vinyl chloride-vinyl acetate resin of pigment carrier and preparation method thereof

The invention belongs to the technical field of resin heat stabilizing agent preparation, and particularly relates to a calcium-zinc heat stabilizing agent for vinyl chloride-vinyl acetate resin of apigment carrier and a preparation method thereof. The heat stabilizing agent is prepared from 6 to 14 percent of calcium oleate, 3 to 9 percent of zinc isoocatanoate or zinc stearate, 1 to 5 percent of beta diketone, 1 to 3 percent of auxiliary antioxidants and 1 to 3 percent of antioxidants and liquid solvents. In the preparation process, the addition of a great number of epoxy plasticizers is not needed; the required raw material types are few; the cost is low; the preparation method is simple. The obtained vinyl chloride-vinyl acetate resin is nontoxic and harmless, conforms to the nationalenvironment protection requirements, can effectively inhibit the aging of the vinyl chloride-vinyl acetate resin, and has relatively good application prospects in the field of the vinyl chloride-vinyl acetate resin stabilizin
