Abstract

The invention discloses a novel slow-release PVC environment-friendly stabilizer, which comprises the following components in percentage by weight: 15%-21% of zinc stearate, 3%-7% of calcium stearate,8%-12% of Sika, 1%-3% of uracil, 33%-43% of zeolite, 5%-11% of calcium hydroxide, 2%-4% of an antioxidant, 7%-13% of a synergistic heat stabilizer and 4%-8% of polyol. The invention relates to the technical field of PVC stabilizers. The novel slow-release PVC environment-friendly stabilizer solves the problems that in the prior art, a composite stabilizer is single in performance, the performanceof PVC cannot be well improved, and meanwhile the release speed is too high and the stabilizer efficiency is low.

Description

technical field [0001] The invention relates to the technical field of PVC stabilizers, in particular to a new slow-release PVC environment-friendly stabilizer. 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, which cannot improve the performance of polyvinyl chloride well, and at the same time, the release speed is too fast, and the efficiency of the stabilizer is not high. Contents of the invention [0004] (1) Solved technical problems [0005...
