Abstract

The invention discloses a freezing-tolerant crack-resistant coating for exhaust equipment. The coating is made from the following raw materials: coal ash, an organosilicon-modified acrylic resin, toluene diisocyanate, zinc oxide, butyl cellulose, butyl acetate, an antifoaming agent BYK535, polyurethane, aluminium powder, silicon carbide powder, styrene, azodiisobutyronitrile, waterborne polyurethane, glycol, sodium dodecyl sulfate, a silane coupling agent a171, nanometer silica, a zirconia sol and a proper amount of absolute ethanol. The coating has preferable fouling resistance, alkali resistance, aging resistance and washing resistance, and has excellent freezing tolerance and crack resistance, and therefore can be used in the low-temperature environment. The equipment is protected, the service life of the equipment is prolonged, and thus the coating has high practical value.

Description

technical field [0001] The invention relates to the technical field of coatings, in particular to a frost-resistant and crack-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 heat radiation, ...
