Polyurethane composition for road repair, polyurethane resin, road repair material and construction method
The invention relates to a polyurethane composition for road repair, polyurethane resin, a road repair material and a construction method, the polyurethane composition comprises a component A and a component B. The component A comprises a polyurethane prepolymer; the polyurethane prepolymer is prepared from the following components in parts by weight: 100 parts of first polyol and 100 to 800 parts of polyisocyanate; the component B is prepared from the following components in parts by weight: 100 parts of second polyol, 80 to 280 parts of water glass, 0.05 to 0.25 part of catalyst, 1 to 5 parts of coupling agent, 0.5 to 2.5 parts of defoaming agent and 0.5 to 5 parts of surfactant; in the polyurethane composition, the mass ratio of the component A to the component B is 1: (0.5-2.5). When the polyurethane resin obtained by mixing the polyurethane composition for road repair is used for pavement repair, the curing speed is high, the hardness is high, the bonding strength is high, the service life is longer, the durability is higher, and the repaired pavement is not easy to wear.
本发明涉及一种用于道路修补的聚氨酯组合物、聚氨酯树脂、道路修补材料及施工方法，该聚氨酯组合物包含A组分和B组分，A组分包含聚氨酯预聚物；聚氨酯预聚物由如下重量份数的组分制备得到：第一多元醇100份和多异氰酸酯100～800份；B组分包含：第二多元醇100份，水玻璃80～280份，催化剂0.05～0.25份，偶联剂1～5份，消泡剂0.5～2.5份和表面活性剂0.5～5份；在所述聚氨酯组合物中，A组分和B组分的质量比为1：(0.5～2.5)。本发明用于道路修补的聚氨酯组合物混合所得聚氨酯树脂在用于路面修补时，固化速度快，硬度高，粘结强度高，具有更长的使用寿命和耐用性，修补后路面不易磨损。
