Abstract

The invention discloses an ultra-heat-resistant high-temperature-resistant coating for exhaust equipment. The coating is made from the following raw materials: fine magnesia powder, an epoxy phenol novolac resin F51, a bisphenol epoxy resin, n-butanol, a modified aliphatic curing agent 2280, nanometer chitin, tributyl citrate, glycerol, asbestos powder, waste ceramics powder, coal ash, dimethyl siloxane, sepiolite fabric, aluminium powder, sodium tripolyphosphate, styrene, azodiisobutyronitrile, a rare earth coupling agent, palmitic acid, a styrene-acrylic emulsion, butyl methacrylate, polyvinyl alcohol, benzoyl peroxide and a proper amount of absolute ethanol. The coating has excellent water resistance and chemical resistance and wear resistance, and is fast to dry and convenient to apply. Through addition of nanometer chitin and asbestos powder, compactness of a coating film is improved, and thermal resistance and high temperature resistance of the coating are improved. The coating is easy to apply, has good adhesion to a material, and is not easy to burn.

Description

technical field [0001] The invention relates to the technical field of coatings, in particular to a super heat-resistant and high-temperature-resistant coating for 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 ...
