Problems solved by technology

[0006] Aiming at the deficiencies of the prior art, the present invention provides a raw material formula and preparation method of a lead-free, non-toxic and environmentally friendly PVC profile, which solves the problem that the existing PVC profile heat stabilizer is highly toxic, pollutes the environment, and cannot achieve environmental protection. The purpose of the PVC material thus obtained will seriously pollute the environment in the process of waste treatment, and it cannot be achieved by using a lead-free, non-toxic and environmentally friendly heat stabilizer to replace the existing toxic and non-environmentally friendly heat stabilizer. The use of organic composite heat stabilizers for the production and processing of PVC materials to achieve the purpose of PVC environmental protection effect

Abstract

The invention discloses a lead-removal nontoxic environment-friendly PVC (polyvinyl chloride) profile raw material formula and a preparation method. The formula comprises the following raw materials in parts by weight: 50-60 parts of a PVC resin, 5-10 parts of a fatty acid thermal stabilizer, 1-5 parts of a light stabilizer, 1-5 parts of a polyhydric alcohol material, 1-5 parts of phosphite ester, 5-10 parts of an organic tin thermal stabilizer and 1-5 parts of an antioxidant. By adopting the lead-removal nontoxic environment-friendly PVC profile raw material formula and the preparation method, a conventional toxic and environment-harmful thermal stabilizer can be replaced by a leadless nontoxic environment-friendly composite thermal stabilizer, production processing of a PVC material is implemented with an organic composite thermal stabilizer, then the purpose of a PVC environment-friendly effect can be achieved, the material is nontoxic and friendly to the environment, the purpose of environment protection can be very well achieved, and the prepared PVC material does not pollute the environment in the waste treatment process, and has beneficial effects on production and use of PVC profiles.

Description

technical field [0001] The invention relates to the technical field of building materials, in particular to a raw material formula and a preparation method of a lead-removing, non-toxic and environment-friendly PVC profile. Background technique [0002] PVC is a white powder with an amorphous structure, a small degree of branching, a relative density of about 1.4, a glass transition temperature of 77-90°C, and begins to decompose at about 170°C. It has poor stability to light and heat. When exposed to sunlight, it will decompose to produce hydrogen chloride, and further autocatalyze the decomposition, causing discoloration and rapid decline in physical and mechanical properties. In practical applications, stabilizers must be added to improve the stability to heat and light. [0003] PVC heat stabilizer should be a multifunctional substance, or a mixture of some materials, which can achieve the following functions: one is to replace active and unstable substituents; the other...
