Micro-expansive self-repaired polyurethane waterproof mortar as well as preparation method thereof
The invention provides a micro-expansive self-repaired polyurethane waterproof mortar which comprises the following components in parts by weight: 60-90 parts of a water hardened mortar aggregate system containing organic silicon active matters, 5-25 parts of a compound polyol emulsion system and 5-25 parts of an isocyanate curing agent, wherein the water hardened mortar aggregate system comprises the organic silicon active matters and cement mortar in a mass ratio of 1-7 to 93-99; the compound polyol emulsion system comprises polyol resin, castor oil polyol resin, an emulsifier and water in a mass ratio of 4-30 to 8-50 to 0.05-0.3 to 10-40. The invention further provides a preparation method of the micro-expansive self-repaired polyurethane waterproof mortar. The waterproof mortar is simple in preparation process and convenient to construct and the cured and formed mortar is good in micro-expansive performance and excellent in self-repairing performance. Moreover, the mortar further has self compacting capability, shock resistance, wear resistance, and hydrophobic property and waterproof performance.
