Abstract

The invention discloses a protective coating used for the surface of exhaust equipment. The coating is made from the following raw materials: polyaryletherketone, fatty acyl diethanol amine, n-butanol, benzenesulfonyl chloride, acetone, a phenolic resin, an alkyd resin, cobalt naphthenate, chromium chloride, coal ash, aluminium powder, polysiloxane, nanometer kaolin, polyacrylamide, styrene, azodiisobutyronitrile, polycarbonate, turpentine, a cross-linking agent TAC, cellulose acetate, N,N-dimethyl formamide, EDTA, aluminium hydroxide, nanometer carbon fiber, and a proper amount of absolute ethanol. The coating is reasonably controllable in technical process, simple to operate, high in adhesive force of a coating layer, and excellent in corrosion resistance, wear resistance and stickiness. The coating can prolong the service life of a material of exhaust equipment, enables cost to be reduced, and is worthy of popularization.

Description

technical field [0001] The invention relates to the technical field of coatings, in particular to a protective coating for the surface of exhaust equipment. Background technique [0002] The shell surface of the exhaust equipment will be painted with different paints to ensure that the shell is not damaged and prolong the service life of the equipment. Aluminum pigments are widely used in traditional solvent-based coatings and inks due to their special metallic luster and "color flop" effect. It has excellent metal effect and large demand. Flake aluminum powder has a good ability to reflect light and heat radiation, and forms a continuous metal film in the coating, which can reflect visible light, ultraviolet rays and infrared rays. The reflection of the full spectrum of visible light is silvery white, which makes it have good decorative performance, and the reflection of infrared rays makes it have the thermal insulation performance of reflecting heat radiation, while the ...
