Abstract

The invention relates to the technical field of chemical stabilizers and in particular to preparation and application of a novel environmental-friendly cyanuric acid compound stabilizer special for a PVC profile. The preparation comprises the following steps: forming a basic catalyst by adopting caustic soda (sodium hydroxide), taking zinc oxide as a raw material, and directly reacting to produce cyanuric acid; neutralizing the basic catalyst by utilizing industrial stearic acid, taking the produced sodium stearate as a surfactant of zinc cyanurate; compounding an auxiliary stabilizer, a lubricating agent, an antioxidant, zinc stearate, calcium stearate and zinc cyanurate according to a set formula. Compared with the traditional heat stabilizer, the cyanuric acid is capable of improving the plasticizing quality of the PVC profile; due to the added lubricating agent, a phenomenon of flow velocity disorder occurring in material processing and production is avoided, so that production and processing can be normally performed, and the inherent quality and appearance quality are improved. Moreover, the stabilizer is environmental-friendly and non-toxic, has high heat stability and processability as well as wide application prospects in the PVC profile industry.

Description

technical field

[0001] The invention relates to the technical field of organic compound synthesis, and specifically designs the preparation and application of a novel cyanuric acid composite stabilizer specially used for environment-friendly PVC profiled materials. Background technique

[0002] Polyvinyl chloride [poly (vinyl choride), PVC] is one of the five largest synthetic resins in the world. It is a thermoplastic linear polymer produced by free radical polymerization of vinyl chloride monomer. PVC material has the advantages of high strength, low price, good chemical corrosion resistance, good electrical insulation and difficult to burn, and is easy to process. It can be processed by molding, lamination, injection molding and other methods. It is widely used in engineering construction, Hard and soft products in food packaging, electrical and other industries. With the further expansion of application fields, the demand for PVC will continue to increase. PVC profiles...
