Abstract
The invention discloses a single-component highly-elastic water-borne polyurethane building water proof coating, and its formula in weight percent: polyurethane emulsion 40-80, color filler 10-40, dispersant 0.3-1.0, film forming auxiliary 0.8-1.2, flow agent 0.1-0.4, defoaming agent 0.1-0.3, plasticizer 0.1-10, thickening agent 0.1-1.0, pH stabilizer 0.1-7.0, UV light absorbent 0.5-1.0 and water 1-15. Its preparing steps: blending dispersant, film forming auxiliary, defoaming agent, plasticizer and pH stabilizer according to the above formula in the water for 20 minutes, adding in color filler to make high-speed dispersion for 30 minutes, then pouring slowly polyurethane emulsion in to blending at low speed for 20 minutes, then adding in flow agent, defoaming agent, and thickening agent to continue low-speed blending for 20 minutes, and obtaining it. By detected, its tensile strength is 3.4 MPa, its rupture elongation is 580%, its low-temperature flexibility is -30 deg.C.
Description
Background technology
The polymer emulsion of preparation polymer emulsion waterproof paint is confined to polyacrylic ester (pure third) emulsion at present, the EVA emulsion, benzene emulsion; styrene-butadiene emulsion etc.; the polymer emulsion waterproof paint performance of above-mentioned emulsion configuration is lower; only meet tensile strength 〉=1.5MPa that polymer emulsion waterproof paint standard (JC/T864-2000) is stipulated substantially as its salient features, tension set 〉=300%, low temperature flexibility are about-20 ℃.
Summary of the invention
The objective of the invention is provides monocomponent high elastic aqueous polyurethane building water-proof paint of a kind of high tensile, high tension set, very low temperature flexibility and preparation method thereof in order to overcome the lower shortcoming of present preparation polymer emulsion waterproof paint performance.
Technical scheme of the present invention is: a kind of monocomponent high elastic aqueous polyurethane building water-proof paint, and its prescription is:
Constituent proportioning (weight part %)
