Abstract

The invention discloses epoxy polyether polyol and a production process thereof. The epoxy polyether polyol is characterized by comprising the following components in parts by weight: 1-3 parts of a catalyst, 95-105 parts of a mixture of glycerol and polyglycerol, and 0.15-0.4 part of an antioxidant. By adopting epoxy polyether polyol, the toughness of a product can be effectively improved, and decomposition of epoxy polyether polyol macromolecules can be effectively inhibited.

Description

technical field [0001] The invention relates to the technical field of plastic toughening agents, in particular to an epoxy polyether alcohol and a production process thereof. Background technique [0002] Glycerin is a colorless, odorless, sweet, clear thick liquid, chemically named "glycerol". Glycerol is mainly used as a stationary liquid for gas chromatography and organic synthesis, and can also be used as a solvent, shock absorber for gas meters and hydraulic machines, softener, nutrient for antibiotic fermentation, desiccant, etc. In recent years, my country's glycerin industry has developed very rapidly, and subsequently, many by-products discharged from the glycerin industry have caused pollution problems to the environment. The general technology of glycerin by-products is to react with fatty acids to produce surfactants after desalting and decolorization. Surfactants are a class of organic compounds that can reduce surface tension by adding a small amount, so the...
