Abstract

The invention relates to the field of coatings, and discloses an environment-friendly water-soluble coating and a preparation method thereof. The coating is composed of the following raw materials inparts by mass: 20-30 parts of flame-retardant macromolecular functional fillers, 80-100 parts of epoxy resin, 20-30 parts of a water-based curing agent and 15-25 parts of water. The environment-friendly water-soluble coating provided by the invention has good binding force with a substrate, can rapidly form charcoal in a fireproofing process, and solves the problems of poor heat resistance and lowflame retarding efficiency of a traditional bio-based water-soluble coating.

Description

technical field [0001] The invention relates to the technical field of coatings, in particular to an environmentally friendly water-soluble coating with good bonding force with a substrate, good flame retardant effect, non-toxic and environment-friendly, wide source of raw materials and low price. Background technique [0002] In recent years, most of my country's civil and commercial products are flammable. According to statistics from relevant departments, large and small fires in my country will cause economic losses of more than 500 million yuan to the society every year. Therefore, it is necessary to carry out flame-retardant treatment for various products It is an important and rigorous work. At present, coating flame-retardant coatings for this problem is the most effective treatment method for flame-retardant products. Therefore, the production and application of high-performance flame retardants have played a huge role in protecting human life, health and social pro...
