Problems solved by technology

However, the traditional epoxy resin needs to be diluted with a large amount of alcohol, ether and ketone organic solvents during construction. A large amount of organic volatiles will not only pollute the environment, but also seriously endanger human health. Therefore, the development of low-cost VOC (volatile organic compound) waterborne epoxy resin system and related coating products have become a new research direction

Abstract

The invention belongs to the field of polymer materials. A low-VOC water-based epoxy emulsion prepared from the following components: epoxy resin, methylvinyldimethoxysilane, initiator, reactive emulsifier, acrylate monomer, epoxy diluent and Water; wherein, the reactive emulsifier is prepared from the following components: epoxy resin, monopolyethylene glycol monomethyl ether maleate and basic catalyst. The water-based epoxy emulsion of the invention has low viscosity, small particle size, good dispersibility, stability, water resistance and flexibility, does not contain organic volatile matter, and is environmentally friendly and pollution-free.

Description

technical field [0001] The invention belongs to the field of polymer materials, and relates to a low-VOC water-based epoxy emulsion and a preparation method thereof. Background technique [0002] Traditional epoxy resins have good adhesion, abrasion and scratch resistance, chemical resistance, low curing shrinkage, and excellent solvent resistance, and are widely used in adhesives, coatings, and floors. However, the traditional epoxy resin needs to be diluted with a large amount of alcohol, ether and ketone organic solvents during construction. A large amount of organic volatiles will not only pollute the environment, but also seriously endanger human health. Therefore, the development of low-cost VOC (volatile organic compound) waterborne epoxy resin system and its related coating products have become a new research direction. Contents of the invention [0003] The technical problem to be solved by the present invention is to provide a low-VOC water-based epoxy emulsion,...
