Abstract

The invention provides a chlorcosane stabilizer and belongs to the technical field of stabilizers. The chlorcosane stabilizer is prepared by mixing ethylene glycol diglycidyl ether, a complex rare earth stabilizer, phosphite, a complex antioxidant, metoxyphenol and ethlene bis stearamide, wherein the weight ratio of ethylene glycol diglycidyl ether to the complex rare earth stabilizer to phophite is (42-60):10:(5-6), the complex antioxidant accounts for 1-2% the total weight of the stabilizer, metoxyphenol accounts for 1-2% the total weight of the stabilizer, and the ethlene bis stearamide accounts for 1-3% the total weight of the stabilizer. During manufacturing, all the raw materials are mixed to obtain the chlorcosane stabilizer. The stabilizer has the good compatibility with chlorcosane and can remarkably improve the thermal decomposition temperature and ultraviolet light stability of chlorcosane.

Description

【Technical field】 [0001] The invention relates to the technical field of heat stabilizers, in particular to a chlorinated paraffin stabilizer and a preparation method thereof. 【Background technique】 [0002] Chlorinated paraffin is a light yellow to orange-yellow viscous liquid, which is a mixture of chlorinated derivatives of straight-chain alkanes with different carbon numbers of C10-C30 undergoing free radical reaction with chlorine gas. Chlorinated paraffin has the characteristics of odorless, non-toxic, flame retardant, low volatility and good compatibility with PVC resin. Additives, anticoagulants, and flame retardants for plastics and rubber, etc. Because chlorinated paraffin contains a small or trace amount of unstable chlorine atoms on tertiary carbon atoms, when exposed to heat or sunlight, such unstable chlorine atoms will detach from the carbon chain at the same time as the adjacent hydrogen atoms, releasing HCl, HCl It can further promote the decomposition of ...
