Abstract

The invention discloses an eco-friendly antirust coating for exhaust equipment. The coating is made from the following raw materials: carbonyl iron powder, polyvinyl butyral, calcium tripolyphosphate, coal ash, aluminium powder, an epoxy resin E44, an epoxy resin E20, polyvinyl alcohol castor oil, butyl acetate, hexamethylenediamine, polyamide, styrene, azodiisobutyronitrile, polyaluminum ferric silicate, isobutene triethoxysilane, polymerized ferrophosphorous powder, phytic acid, ureidopropyltrimethoxysilane, bismuth germanate, an aluminate coupling agent and a proper amount of absolute ethanol. The coating is safe and free of toxicity, is high in adhesive force and good in rust resistance, wear resistance and impact resistance, and can keep excellent characteristics in the severe environment. Through use of the coating, the service life of a material is prolonged and the cost is reduced, and therefore the coating is worthy of popularization.

Description

technical field [0001] The invention relates to the technical field of coatings, in particular to an environmentally friendly antirust 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, w...
