Problems solved by technology

Since benzene and other co-solvents are not added to the coating, good solubility cannot be achieved, which will lead to poor performance of the coating, and a large amount of solvent cleaning is required after construction, wasting resources and polluting the environment

Abstract

The invention provides a fireproof explosion-proof water-based environment-friendly coating for an automobile engine compartment. The coating is prepared from the following components in parts by weight: 40 to 60 parts of water-based resin, 5 to 10 parts of phosphate anti-rust pigment, 4 to 6 parts of nanometer inorganic pigment, 0.1 to 0.5 part of a flatting agent, 0.1 to 0.5 part of a defoaming agent, 0.5 to 1.5 parts of a dispersing agent, 0.1 to 3 parts of an anti-settling agent and 15 to 30 parts of deionized water. The water-based acrylic resin and the water-based epoxy modified acrylic resin form a firm resin network structure, and then the sulfate anti-rust pigment and the nanometer inorganic filler are added, so the heat resistance, wear resistance and fire resistance of the coating are enhanced, and the coating can resist high temperature of 600 DEG C or above and has good fire and explosion resistance.

Description

Technical field [0001] The present invention belongs to the technical field of coatings, and in particular to an automobile engine compartment fire prevention and explosion-proof waterborne coating. Background technique [0002] The main role of automotive engine coating is to protect the engine and a certain decorative effect. The coating of the engine can generally be divided into a coating of the engine assembly, the coating of the heat sink and the coating of the engine cover. The engine assembly includes an engine cylinder, a flywheel, a transmission, and the like, and the mechanism of these parts should often contact gasoline, diesel, oil and water, etc. So choose fire explosion-explosive lacquer. [0003] In order to avoid environmental pollution, protect production and construction personnel, green, environmentally friendly, and healthy fire explosion-proof coating research is imperative. In the prior art, aqueous environmentally friendly fire-resistant coating is usually...
