Abstract

The invention relates to a method for preparing environment-friendly calcium-zinc composite stabilizing agent, in particular to a method for preparing the environmental-friendly calcium-zinc composite stabilizing agent by adopting efficient chelating technology. The four ingredients of binary or multivariate saturated acid calcium, binary or multivariate saturated acid zinc, antioxidant and co-stabilizer are mixed in a reaction kettle according to certain mass ratios, the mixture is heated in the reaction kettle, and chelating agent with the mass ratio of 5 to 10 percent is added, when the reaction temperature is controlled to be higher than the melting point of lubricant, about 10 to 20 percent of the lubricant is added to the reaction kettle, the mixture is fully mixed, and then the mixture is cooled to a normal-temperature state and stirred at a low speed, thus obtaining the product. The method has the advantages that the coating of the calcium-zinc composite stabilizing agent is modified at a temperature higher than the melting point of the lubricant, thus greatly reducing the hydroscopic property and further increasing the electric resistivity of PVC products. Simultaneously, the stabilizer of static coating modification is more beneficial to PVC dispersion, thus improving the stabilizing effect.

Description

technical field [0001] The invention relates to a preparation method of a chemical stabilizer, in particular to a preparation method of an environment-friendly calcium-zinc composite liquid stabilizer. technical background [0002] Polyvinyl chloride (PVC) is one of the most widely used synthetic resins in the world. It has the characteristics of light weight, high strength, flame retardancy, corrosion resistance, insulation, and transparency. PVC begins to decompose obviously at 100-150°C, and ultraviolet mechanical force, oxygen, ozone, hydrogen chloride and active metal ions will greatly accelerate the decomposition of PVC. The thermal oxygen aging of PVC is more complicated, and several chemical reaction processes are carried out at the same time. There are not only decomposition and dehydrochlorination, but also oxidative chain scission and crosslinking. In addition, there is a reaction process of a small amount of aromatization and macromolecular chain scission to gen...
