Water-based bamboo and wood cultural relic protective coating and preparation and application methods thereof

Abstract

The invention discloses a water-based bamboo and wood cultural relic protective coating. The coating is formed by a first component and a second component in a mass ratio of (1 to 1)-(1 to 2), wherein the first component comprises the following components in parts by weight: 90-120 parts of acrylic polyurethane aqueous dispersion, 0.5-1.5 parts of thickening agent and 5-20 parts of water; the second component comprises the following components in parts by weight: 2-8 parts of propylene glycol monomethyl ether acetate, 0.5-5 parts of dispersing agent, 0.2-0.8 part of defoaming agent, 10-30 parts of water, 2-8 parts of flame retardant, 10-20 parts of mould inhibitor and 4-8 parts of plant mothproofing agent. The invention also discloses preparation and application methods of the water-based bamboo and wood cultural relic protective coating. The water-based bamboo and wood cultural relic protective coating forms a fireproof, waterproof, mouldproof and mothproof coat on the surfaces of bamboo and wood cultural relics and is environment-friendly and does not pollute the cultural relics.
