Epoxy modified polyurethane road repairing material and preparation method thereof
The invention provides an epoxy modified polyurethane road repairing material and a preparation method thereof. The epoxy modified polyurethane road repairing material provided by the invention comprises a component A, a component B and a component C. Raw materials in each component are proportioned in parts by weight. The component A comprises the following raw materials in parts by weight: 100 parts of polyether polyol, 20-60 parts of isocyanate, 10-50 parts of epoxy resin and 5-15 parts of a plasticizer; the component B comprises the following components in parts by weight: 5-25 parts of an amine curing chain extender, 2-30 parts of tertiary amine polyether glycol, 0.5-3 parts of an accelerant, 1-5 parts of a thixotropic agent and 5-20 parts of a diluent; and the component C is aggregate. The weight ratio of the component A to the component B is (3-10): 1, and the ratio of the weight sum of the component A and the component B to the weight of the component C is 1: (3-10). The epoxy modified polyurethane road repairing material disclosed by the invention can be used for quickly repairing damaged pit slots of roads, and has good toughness and mechanical properties.
本发明提供了一种环氧改性聚氨酯道路修复材料及制备方法，本发明所提供的环氧改性聚氨酯道路修复材料包括A组分、B组分和C组分，各组分中的原料配比以重量份计，其中，A组分包括100份聚醚多元醇、20～60份异氰酸酯、10～50份环氧树脂和5～15份增塑剂；B组分包括5～25份胺类固化扩链剂、2～30份叔胺基聚醚二醇、0.5～3份促进剂、1～5份触变剂和5～20份稀释剂；C组分为集料。并且，A组分与B组分的重量配比为3～10：1，A组分和B组分的重量之和与C组分的重量之比为1：3～10。本发明的环氧改性聚氨酯道路修复材料，可用于道路破损坑槽的快速修复，并具有良好的韧性和力学性能。
