Abstract

The invention discloses a wearing-resistant fire-resistant coating for an air compressor and belongs to the technical field of coatings. The coating comprises the following raw materials in parts by weight: 36-40 parts of a brominated epoxy resin, 18-24 parts of polyvinylidene fluoride, 10-12 parts of aluminum silicate, 5-7 parts of emery powder, 3-5 parts of cast stone powder, 6-7 parts of zinc oxide, 2-5 parts of expanded perlite, 6-8 parts of m-dihydroxybenzene (diphenyl phosphate), 5-7 parts of melamine phosphate, 9-11 parts of triethyl citrate, 3-5 parts of sodium silicate, 0.5-1 part of carboxymethylcellulose, 1-3 parts of a defoaming agent, 0.2-0.8 part of an anti-electrostatic agent, 4-6 parts of a coupling agent, 14-18 parts of methanol and 17-20 parts of water. The invention further discloses a preparation method of the wearing-resistant fire-resistant coating for the air compressor. The coating is relatively high in wearing resistance and fireproof effect, high in corrosion resistance and long in service life.

Description

technical field [0001] The invention relates to the technical field of coatings, in particular to a wear-resistant and refractory coating for an air compressor and a preparation method thereof. Background technique [0002] Fireproof coating is a special coating used on the surface of flammable substrates, which can reduce the flammability of the surface of the coated material, retard the rapid spread of fire, and improve the fire resistance limit of the coated material. [0003] The fire prevention mechanism of fire retardant coatings can be roughly summarized into the following five points: 1. The fire retardant coating itself is flame retardant or non-combustible, so that the protected substrate does not directly contact with the air, delaying the ignition of objects and reducing the burning speed; 2. Fire retardant coatings In addition to being flame-retardant or non-combustible, it also has a low thermal conductivity, which can delay the transfer of flame temperature to...
