Abstract

The invention discloses a toughened heat resistant type environmentally-friendly efficient compound stabilizer and a preparation technology, and relates to the field of the compound stabilizer. The toughened heat resistant type environmentally-friendly efficient compound stabilizer is prepared from the following components in percentage by weight: 30-40% of zinc stearate, 5-15% of calcium stearate, 1-3% of diphenyl formyl methane, 2-8% of polyhydric alcohols, 2-8% of hydrotalcite, 2-8% of phosphite ester, 4-18% of zeolite, 1-3% of antioxidant, 2-8% of methyl methacrylate, 2-8% of butadiene-acrylonitrile glue and 10-20% of Fischer Tropsch wax. The toughened heat resistant type environmentally-friendly efficient compound stabilizer has the beneficial effects that the stability and anti-impact tensile strength of PVC (polyvinyl chloride) are improved by utilizing the synergistic effect and complementary effect of multiple organic matters, and meanwhile the two large problems of poor temperature tolerance and low modified efficiency of the PVC product are solved; the additive amount of the compound stabilizer is one half of the additive amount of similar products, but the effect of the compound stabilizer exceeds the effect of the similar products by 20%, so that the two problems are solved by one kind of product; the comprehensive cost of the product is reduced; the preparation technology is simple and easy to operate; and the production efficiency is improved.

Description

technical field [0001] The invention relates to the field of composite stabilizers, in particular to a toughening and heat-resistant environment-friendly and high-efficiency composite stabilizer and a preparation process thereof. Background technique [0002] As one of the five general-purpose plastics, polyvinyl chloride has gradually developed into one of the main chemical building materials in the 21st century due to its good flame retardancy, chemical corrosion resistance, wear resistance, electrical insulation, and low price. One of the ways to improve the stability of PVC is to add appropriate stabilizers to the processing formula to prevent thermal degradation of PVC and ensure the stability of the product. [0003] However, the performance of the composite stabilizer in the prior art is single, does not have the effect of simultaneously inhibiting the decomposition of PVC and improving the impact tensile strength of PVC, and cannot well improve the performance of pol...
