High-strength polyurethane construction sealant
The invention relates to the technical field of building materials and in particular relates to a high-strength polyurethane construction sealant. The high-strength polyurethane construction sealant is prepared from the following raw materials in parts by weight: 130-150 parts of polypropylene ether trivalent alcohol, 10-20 parts of dimethyl phenyl diisocyanate, 15-25 parts of dioctyl phthalate, 2-6 parts of bismuth isocaprylate, 10-20 parts of polytetrafluoroethylene, 10-22 parts of wollastonite powder, 15-25 parts of sodium silicate, 15-30 parts of sodium chloride, 20-35 parts of alkyl glycoside, 10-25 parts of ethyl acetate and 5-15 parts of dimethyl silicon oil. The high-strength polyurethane construction sealant provided by the invention is high in strength and quick in moistening and curing, does not need long-term protection, and is strong in waterproofing quality, good in aging resistance and good in keeping property.
