Abstract

The invention discloses a high-stability coating with good thermal resistance and adhesion property. The high-stability coating is prepared from the following raw materials: modified polyurethane, epoxy resin, phenolic resin, chlorosulfonated polyethylene, acrylic resin, modified epoxide resin, methyl hydroxyethyl cellulose, methyl ethyl ketone, ethyl acetate, ethyl cellulose, attapulgite, kieselguhr, zinc oxide, calcium sulfate, calcined kaolin, nano-montmorillonite, nano-aluminum hydroxide, organic bentonite, a silane coupling agent KH760, phenyl petroleum sulfonate, citrate, a defoaming agent, an anti-mold agent and a curing agent. The high-stability coating is excellent in thermal resistance, high in pencil hardness and good in adhesion property and stability.

Description

technical field [0001] The invention relates to the field of coatings, in particular to a high-stability coating with high heat resistance and high adhesion. Background technique [0002] Water-based light-curing polyurethane coatings replace traditional oil-based polyurethane coatings with water as the dispersion medium. They have the characteristics of non-toxicity, low energy consumption, fast curing speed, good mechanical properties of the coating film, and high adhesion. The new trend, widely used in automobile, food and other industries. However, due to the poor heat resistance of the coating film of polyurethane materials, its application is limited, and its excellent mechanical properties cannot be widely used. [0003] Therefore, developing a coating with excellent heat resistance, high adhesion and high stability is an urgent problem in the current prior art. Contents of the invention [0004] In order to solve the technical problems in the background technolog...
