Abstract

The invention discloses a low-temperature-resistant two-component styrene acrylic copolymer cement-based 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: (1.2-1.8). The liquid material A is prepared from styrene acrylic emulsion, liquid polysulfide rubber, fluorocarbon resin, octyldodecyl glucoside, dioctyl azelate, sodium dodecyl benzene sulfonate, propylene glycol alginate, polyglutamic acid, triethanolamine oleic soap, polyacrylamide, water and the like; and the powdery material B is prepared from volcanic Portland cement, christobalite, cancrinite, boiler slag, shell powder, phosphate tailings with high magnesium content, calcium metaborate, bischofite, calcium nitrite, etc. According to the invention, through modification of the styrene acrylic emulsion and vulcanic Portland cement, the prepared two-component styrene acrylic copolymer cement-based waterproof coating has excellent low-temperature resistance, has low-temperature flexibility that no crack occurs at a temperature of -40 DEG C, and has excellent water resistance, aging resistance, corrosion resistance and cracking resistance.

Description

technical field [0001] The invention relates to a low-temperature-resistant two-component styrene-acrylic 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 t...
