| titleOfInvention | High-permeability polyurethane graft-modified epoxy resin interpenetrating-network polymer grouting material and preparation method thereof |
| abstract | The invention belongs to the field of construction materials, and particularly relates to a high-permeability polyurethane graft-modified epoxy resin interpenetrating-network polymer grouting material which is composed of a component A and a component B, wherein the component A is composed of 5-30 parts of isocyanate-terminated polyurethane prepolymer, 95-70 parts of epoxy resin and 10-30 parts of diluter I, and the polyurethane and epoxy resin form a grafted interpenetrating network structure; the component B is composed of 40-60 parts of curing agent, 10-30 parts of diluter II, 0.5-2 parts of accelerator and 0.5-2 parts of defoaming agent; and when in use, the components A and B can be evenly mixed to obtain the grouting material. The interpenetrating network grouting material provided by the invention integrates the advantages of the polyurethane and epoxy resin, has the characteristics of high adhesive strength, moderate toughness, high stability, low viscosity, favorable groutability and excellent cost performance, and can be widely used in seepage prevention, leakage stoppage, reinforcement and strengthening of construction, maintenance and other projects of tunnels, hydropower, rock soil slopes, foundation treatment, ground settlement, railways and highways. |
