Problems solved by technology

However, the current fire-resistant and flame-retardant coatings have the following problems: (1) Fire-resistant and flame-retardant coatings generally do not have the effect of anti-fouling and self-cleaning, and cannot meet the requirements of anti-fouling, self-cleaning and flame-retardant required in municipal construction and urban management; (2) Traditional Fire retardant coatings generally add a large amount of flame retardant, and in case of fire, the amount of smoke is large, and the gas produced is highly toxic, which is harmful to the environment and human body.

Abstract

The invention discloses an antifouling and flame-retardant coating, which comprises component A and component B. The component A comprises the following components in parts by weight: 40-45 parts of fluorine-silicon modified polyurethane resin, 0.1-45 parts of antistatic agent 1 part, 0.1-5 parts of flame retardant, 0.1-2 parts of leveling agent, 0.1-2 parts of wetting and dispersing agent and 0.1-1 part of defoamer; the component B includes 40-50 parts of polyisocyanate prepolymer parts; the mass ratio of the component A to the component B is 1:4-10; the fluorosilicon-modified polyurethane resin contains hydroxyl groups. The anti-fouling and flame-retardant coating has the synergistic effect of fluorine-silicon modified polyurethane resin containing hydroxyl groups, polyisocyanate prepolymer and various functional additives, so that the coating has the effect of anti-fouling and self-cleaning, and can also achieve flame retardancy. The effect of fire prevention, the anti-fouling and flame-retardant coating has a small amount of smoke, and has no toxic effect on the environment and human body. The invention also discloses a construction method of the antifouling and flame retardant paint.

Description

technical field [0001] The invention belongs to the technical field of coatings, and in particular relates to an antifouling and flame-retardant coating and a construction method thereof. Background technique [0002] Fire and flame retardant coating is to apply it on the surface of the object to form a coating that expands when it is heated by fire to form a heat insulation layer to achieve the purpose of fire and flame retardancy. Fire-resistant and flame-retardant coatings are used on the surface of flammable substrates to reduce the flammability of the surface of the coated material and retard the rapid spread of fire; used on the surface of non-combustible substrates to improve the fire resistance limit of the coated material coating. The fire-resistant and flame-retardant coating is coated on the surface of the substrate. In addition to being flame-retardant, it also has anti-rust, waterproof, anti-corrosion, wear-resistant and heat-resistant properties. The coating h...
