Description

technical field [0001] The invention relates to the technical field of coatings, in particular to a heat-resistant and flame-retardant modified epoxy resin coating. Background technique [0002] Coating is a material that can be coated on the surface of an object by different construction techniques to form a solid film with strong adhesion, certain strength and continuity. The film formed in this way is commonly called a coating film, also known as a paint film or a coating. Coatings belong to organic chemical polymer materials, and the formed coating film belongs to the type of polymer compounds. According to the classification of modern chemical products, coatings belong to fine chemical products. Modern coatings are gradually becoming a class of multifunctional engineering materials and an important industry in the chemical industry. The heat-resistant and flame-retardant properties of the existing coatings are not ideal, and the curing speed is slow and the curing co...
