Abstract

The invention discloses a flame-retardant two-component polychloroprene copolymer cement-based waterproof coating and a preparation method thereof. The coating is prepared from a liquid material A and a powdery material B in a mass ratio of 1: (1-1.5). The liquid material A is prepared from polychloroprene latex, hexachlorocyclopentadiene, dibromotoluene glycidol ether, tributoxyethyl phosphate, sodium dioctyl sulfosuccinate, beta-cyclodextrin, etc.; and the powdery material B is prepared from composite Portland cement, perlite tailings, aluminum phosphate, hydrated magnesium silicate micropowder, sillimanite, yellow phosphorus slag, etc. The two-component EVA copolymer cement-based waterproof coating prepared in the invention has high-efficiency flame retardation effect and an oxygen index of 35% or above; and the two-component EVA copolymer cement-based waterproof coating has the advantages of high mechanical strength, good weatherability, good corrosion resistance, high binding power, excellent impermeability, etc., and is extensively applicable to waterproof exterior walls of high-rise buildings, waterproof roofs, waterproof basements and anticorrosive pools.

Description

technical field [0001] The invention relates to a flame-retardant two-component chloroprene polymer cement-based waterproof coating and a preparation method thereof, belonging to the field of waterproof coatings. Background technique [0002] Two-component polymer cement-based waterproof coating is a two-component waterproof coating based on water-based polymer dispersion and cement. The two components are stirred on site to form a uniform and fine slurry, which is brushed or sprayed on the surface of the substrate. After curing Form a flexible, high-strength waterproof coating film. This kind of coating not only has the advantages of high strength of cement-based cementitious materials, is easy to bond with wet substrates, but also has the advantages of high elasticity and good water resistance of the polymer coating film. The disadvantage of waterproof coatings polluting the environment is a new type of green and environmentally friendly waterproof coating that is non-tox...
