Abstract

Provided is a preparation method for differentiated EG. The method comprises the following steps that oxalic acid solution, hypochloric acid solution, pucherite, graphene oxide, zinc oxide, titanium dioxide top grade and hydrotalcite are mixed to be grinded after hydrothermal reaction is carried out, and filtration, calcination, washing and drying are carried out to prepare a special age resisterfor EG; ethylene glycol, propylene glycol, glycerinum, lactic acid, the obtained special age resister for EG, silicon dioxide, mica powder and potassium hydrogen phosphate dispersion liquid are mixedand grinded, then dispersion and filtration are carried out to prepare differentiated EG mother liquor with a function of ageing resistance; the obtained differentiated EG mother liquor is sprayed into the EG to prepare the differentiated EG fused deeply with the function of ageing resistance. The preparation method for the differentiated EG has the advantage that the differentiated EG prepared bythe above method has the good function of ageing resistance.

Description

technical field [0001] The invention belongs to the technical field of EG variety development, and in particular relates to a preparation method of differentiated 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 , 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...
