Abstract

The invention discloses a flame-retardant single-component polyurethane waterproof coating material and a preparation method thereof, and belongs to the technical field of waterproof coating materials, wherein the flame-retardant single-component polyurethane waterproof coating material comprises, by weight, 100-200 parts of a flame retardant polyether polyol (FR-600), 50-100 parts of toluene diisocyanate, 200-400 parts of a filler, 10-30 parts of an organic silicon defoamer, 20-50 parts of a latent curing agent, 50-80 parts of a dispersing agent, and 20-30 parts of flame retardant. Accordingto the invention, the flame-retardant single-component polyurethane waterproof coating material has advantages of high binding power with the layer, compact coating, no pinhole, no bubble and small water vapor permeability coefficient, can be directly constructed on the surface of a humid base layer, and has high construction speed so as to shorten the construction period, wherein the flame retardant polyether polyol in the raw material formula has flame retardancy so as to improve the flame retardancy and the stability of the single-component polyurethane waterproof coating material.

Description

technical field [0001] The invention belongs to the technical field of waterproof coatings, in particular to a flame-retardant one-component polyurethane waterproof coating. Background technique [0002] Polyurethane waterproof coatings are prepolymers containing isocyanate groups formed by addition polymerization of isocyanate and polyether, together with catalysts, anhydrous additives, anhydrous fillers, solvents, etc., and processed through mixing and other processes One-component polyurethane waterproof coating. This type of coating is a reaction-curing (moisture-curing) coating, which has the characteristics of high strength, high elongation, and good water resistance. Strong adaptability to base deformation. Polyurethane waterproof coating is a single-component environmentally friendly waterproof coating for liquid construction. It is based on imported polyurethane prepolymer and has no additives such as tar and asphalt. It solidifies after exposure to moisture in t...
