Abstract

The invention provides a compound stabilizer specially used for chloro-methoxy fatty acid methyl ester, belonging to the technical field of heat stabilizers. The compound stabilizer is prepared from the following components by weight percent: 70-80% of ethylene glycol diglycidyl ether, 6-10% of salicylic acid rare earth, 5-8% of organic tin, 5-8% of zinc laurel monomaleate, 1-2% of a composite anti-oxidant, 1-2% of p-methoxyphenol and 1-3% of ethylidene bis-stearamide; the compound stabilizer is prepared by mixing all the raw materials. The compound stabilizer and the chloro-methoxy fatty acid methyl ester have better compatibility, and the compound stabilizer can remarkably improve the thermal decomposition temperature and ultraviolet light resistance stability of the chloro-methoxy fatty acid methyl ester.

Description

【Technical field】 [0001] The invention relates to the technical field of heat stabilizers, in particular to a special composite stabilizer for chloromethoxy fatty acid methyl esters. 【Background technique】 [0002] Chloromethoxy fatty acid methyl ester, referred to as chloromethyl ester, is a kind of product with higher molecular weight produced by transesterification reaction of natural oil and alcohol, and then chlorination reaction. The molecular formula is C 20 h 37 Cl 3 o 3 . Chloromethyl ester has good compatibility with PVC and excellent plasticizing effect. It is a flame-resistant, non-toxic and environmentally friendly compound plasticizer, especially suitable for export products, and also suitable for PVC flame-retardant conveyor belts and cables. Materials, PVC rain boots, PVC hoses, automotive interior leather, artificial leather and sealing strips and other industries. Because the product has an ester structure, it can replace tributyl citrate (TBC) and car...
