Embodiment Construction

[0013] A waterproof coating for exhaust equipment, prepared from the following raw materials in parts by weight (kg): fly ash 20, aluminum powder 6, novolac epoxy resin 30, epoxy resin 50, methyl methacrylate 7, acetic acid Ethyl ester 15, sodium hexametaphosphate 0.7, silicone oil 0.2, fluorinated graphite 1.2, molybdenum titanium powder 5, talc powder 2, styrene 12, azobisisobutyronitrile 1.2, EVA emulsion 2.4, oak powder 0.7, antioxidant 168 0.2, lauroyl diethanolamine 0.3, appropriate amount of absolute ethanol, appropriate amount of deionized water.

[0014] Described a kind of waterproof paint for exhaust equipment is prepared by the following specific steps:

[0015] (1) Soak the fly ash in 3 times the amount of concentrated sulfuric acid for 8 hours, take it out and wash it with deionized water until the filtrate is neutral, dry it through a 200-mesh sieve, and then add butyltin mercaptide with a weight of 1.3% of the dried material , 1.8% rare earth chloride and 0.7%...

Abstract

The invention discloses a waterproof coating for exhaust equipment. The coating is made from the following raw materials: coal ash, aluminium powder, an epoxy phenol novolac resin, an epoxy resin, methyl methacrylate, ethyl acetate, sodium hexametaphosphate, silicone oil, fluorinated graphite, molybdenum titanium powder, talcum powder, styrene, azodiisobutyronitrile, an EVA emulsion, oak powder, an anti-oxidant 168, lauroyl diethanolamine and a proper amount of absolute ethanol and deionized water. The waterproof coating has excellent water resistance, moisture resistance, oil resistance and corrosion resistance, and isn't prone to precipitate during a transportation and storage process. The coating has relatively good binding ability, has preferable crack resistance, and is worthy of popularization.

Description

technical field [0001] The invention relates to the technical field of coatings, in particular to a waterproof 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, while the reflection of u...
