Embodiment Construction

[0013] A refractory coating for exhaust equipment, prepared from the following raw materials in parts by weight (kg): fly ash 21, fluorocarbon resin 78, polyacrylamide 0.6, n-butyl acetate 13, methacrylate 8, polyurethane resin 28. Acrylic leveling agent 0.3, aluminum powder 9, floating beads 2, expanded mica 3, styrene 12, azobisisobutyronitrile 1.2, silicon powder 3, zinc methacrylate 1.2, aluminum dihydrogen tripolyphosphate 0.6, Zirconate coupling agent 0.2, sulfur 2.2, diethanolamine 2.5, sawdust powder 2.8, an appropriate amount of ethanol.

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

[0015] (1) Soak the fly ash in deionized water for 24 hours, filter and dry, then mix the fly ash and sawdust powder well and calcinate at 550°C for 2 hours, after cooling, crush and sieve into 200 mesh, and then mix with zinc methacrylate , aluminum dihydrogen tripolyphosphate, and zirconate coupling agent are ground an...

Abstract

The invention discloses a fireproof coating for exhaust equipment. The coating is made from the following raw materials: coal ash, a fluorocarbon resin, polyacrylamide, n-butyl acetate, methacrylate, a polyurethane resin, an acrylic acid leveling agent, aluminium powder, floaters, expanded mica, styrene, azodiisobutyronitrile, silica powder, zinc methacrylate, aluminum dihydrogen tripolyphosphate, a zirconate coupling agent, sulphur, diethanol amine, sawdust powder and a proper amount of absolute ethanol. The coating has preferable fire retardance and weather resistance, is high in strength and excellent in storage performance, and is convenient to apply. The coating can be operated at a high-temperature environment for a long time and is not easy to spoil. The coating has excellent overall performance and obvious cost advantage, and has bright application prospects.

Description

technical field [0001] The invention relates to the technical field of coatings, in particular to a refractory 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...
