Abstract

The invention discloses a liquid chlorinated paraffin efficient composite stabilizer and a preparation method thereof. The efficient composite stabilizer is prepared from glycidyl ether, phosphite ester and polyhydric alcohol reaction blend, an epoxy compound, an anti-ultraviolet absorbent, an antioxidant, beta-diketone and polyhydric alcohol. According to the invention, phosphite ester and polyolare subjected to a preferential reaction to generate a reaction mixture, then a stabilizer is formed with other components; the liquid chlorinated paraffin stabilizer has the advantages of improvement of the thermal stability of liquid chlorinated paraffin, effective inhibition of the initial coloring of chlorinated paraffin products, improvement of the yellowing resistance of the products, reduction of the decomposition speed of the products, prolongation of the yellowing time, good compatibility with chlorinated paraffin, and low cost. The composite stabilizer has potential market value.

Description

technical field [0001] The invention relates to the field of ingredients for the production of liquid chlorinated paraffin, in particular to a high-efficiency composite stabilizer for liquid chlorinated paraffin and a preparation method thereof. Background technique [0002] Under the influence of heat or light for a long time, liquid chlorinated paraffin products can slowly decompose and release HCl to form chloroalkenes. The released HCl has a self-catalytic effect in chloroalkenes, which further decomposes chloroalkenes. This deep decomposition can even cause carbonization, resulting in blackening of the product and loss of original product performance. In addition, due to the different purity of the raw material paraffin, it may contain unsaturated hydrocarbons, cycloalkanes, high-carbon aromatics, and hydrocarbon derivatives of substituents such as oxygen, nitrogen, and sulfur. In addition, the production process adopts a hot chlorine process, and the reaction temperatu...
