Abstract

The invention relates to a hybrid modified EG preparation method. The preparation method comprises the following steps: mixing a citric acid aqueous solution, indium vanadate, cerium oxide, montmorillonite, a hydrobromic acid aqueous solution, graphene oxide, and tin oxide and performing a hydrothermal reaction, grinding a mixture, and performing steps of filtering, calcining, washing and drying to obtain an EG anti-aging agent; mixing glycol, propylene glycol, butylene glycol, a lactic acid cosolvent and the obtained EG anti-aging agent, magnesium oxide, and titanium dioxide, grinding the mixture, and performing steps of dispersing and filtering to obtain the hybrid modified EG mother liquor; and adding the hybrid modified EG mother liquor in EG in a spray form to obtain the hybrid modified EG. The product has the long lasting anti-aging effect.

Description

technical field [0001] The invention belongs to the technical field of EG variety development, and in particular relates to a preparation method of hybrid modified EG. Background technique [0002] EG is called ethylene glycol in Chinese and ethylene glycol in English, also known as "glycol", "1,2-ethylene glycol", or EG for short. Its chemical formula is (CH2OH) 2 , is the simplest diol. EG is a colorless, odorless, sweet liquid that can be mixed with water in any proportion and used as a raw material for solvents, antifreeze agents, and synthetic resins. In resin synthesis, the most common method is to use EG and purified terephthalic acid as monomer raw materials for synthesis. The synthetic material prepared by it has the characteristics of high strength, good rigidity, high hardness and toughness, and is widely used in industrial production and In people's life, such as engineering plastics, building materials, mechanical parts, beverage bottles, packaging films, fil...
