Abstract

The invention provides an environment-friendly calcium-zinc stabilizer applied to a low-temperature-resistant and high-impact-resistant PVC corrugated pipe, and relates to the technical field of PVC corrugated pipe manufacturing. Theenvironment-friendly calcium-zinc stabilizer comprises 15-21 parts of zinc stearate, 7-13 parts of calcium stearate, 3-7 parts of THEIC, 1-3 parts of uracil, 20-30 parts of zeolite, 8-12 parts of hydrotalcite, 3-5 parts of an antioxidant, 5-15 parts of a synergistic heat stabilizer, 6-10 parts of a high-end lubricant and 8-12 parts of polyol, wherein the raw materials are proportioned according to the metering ratio, and composite manufacture is performed. According to the invention, after the environment-friendly calcium-zinc stabilizer is applied to processing of PVC corrugated pipes, the heat stabilizer is strong, the production period is long, separating out is avoided, and the low-temperature-resistant and high-impact-resistant performance of the product can meet related index requirements.

Description

technical field [0001] The invention relates to the technical field of PVC corrugated pipe manufacturing, in particular to an environmentally friendly calcium-zinc stabilizer applied to a low-temperature-resistant and high-impact-resistant PVC corrugated pipe. Background technique [0002] PVC is a polymer formed by the polymerization of vinyl chloride monomer (VCM) in peroxide, azo compound and other initiators or under the action of light and heat according to the mechanism of free radical polymerization. Vinyl chloride homopolymers and vinyl chloride copolymers are collectively referred to as vinyl chloride resins, and are white powders with an amorphous structure. Poor stability, above 100°C or after long-term sunlight exposure, it will decompose to produce hydrogen chloride, and further autocatalyze and decompose, causing discoloration and rapid decline in physical and mechanical properties. In practical applications, stabilizers must be added to improve heat resistance...
