Abstract

The invention discloses a preparation method of EG. The preparation method comprises: mixing an oxalic acid solution, a hypochlorous acid solution, bismuth vanadate, graphene oxide, rutile type titanium oxide and hydrotalcite, carrying out a hydrothermal reaction, grinding, filtering, calcining, washing, and drying to prepare a special anti-aging agent for EG; mixing ethylene glycol, propylene glycol, glycerin, the obtained special anti-aging agent for EG, silica, mica powder and a potassium hydrogen phosphate dispersion liquid, grinding, dispersing, and filtering to prepare a differentiated EG mother liquor with anti-aging function; and adding the obtained spraying-like differentiated EG mother liquor to EG to prepare the deep-fused differentiated EG having anti-aging function. The product prepared through the method of the invention has excellent anti-aging function.

Description

technical field [0001] The invention belongs to the technical field of EG variety development, and in particular relates to a preparation method of EG. Background technique [0002] The Chinese name of EG is ethylene glycol, and the English name is ethylene glycol, referred to as EG. Its chemical formula is (CH2OH)2, which is the simplest diol. As a basic chemical raw material, EG is active in nature and can undergo reactions such as esterification, etherification, alcoholization, oxidation, acetalization, and dehydration. EG molecules have two hydroxyl functional groups, so they are mainly used to prepare synthetic materials such as polymers, such as engineering plastics, building materials, mechanical parts, beverage bottles, packaging films, films, clothing, films and other products, and there are more and more More and more products are used in the outdoor environment, and they are constantly eroded by factors such as wind and rain, sunlight and ultraviolet rays, and c...
