Abstract

A preparation method of a high-efficiency compound stabilizer of chlorinated paraffin comprises the following steps of: (1) uniformly mixing 50-55 parts by weight of glycol diglycidyl ether and methyltin, adding triphenyl phosphite, after intensive and uniform mixing, adding a catalyst, slowly heating to 145-150 DEG C, holding the temperature for 3h, rising the temperature to 160-170 DEG, holding the temperature for 30min, cooling to the room temperature to form a solution A, (2) pouring epoxy soybean oil into the solution A, then adding chlorinated paraffin-52 into the solution A to form a solution B, and (3) slowly heating the solution B to raise the temperature to 50-60 DEG C, continuing stirring for 15-20min, adding an ultraviolet absorber and an antioxidant, and stirring to complete dissolution to form the high-efficiency compound stabilizer of the chlorinated paraffin. The inventor of the invention finds that the solution can form a stable system and the storage stability is better via many repeated tests.

Description

technical field [0001] The invention belongs to the technical field of chemical industry, and specifically refers to a preparation method of a chlorinated paraffin high-efficiency composite stabilizer. 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 to C30 through 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. 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 d...
