Abstract

The invention discloses a polyurethane chemical grouting water plugging-reinforcing material which comprises a component A and a component B. The invention is characterized in that the component A is composed of polyether glycol and auxiliary materials, and the component B is composed of isocyanate and / or prepolymer thereof and auxiliary materials; and the auxiliary materials comprise catalyst, foam stabilizer and other assistants. The polyurethane chemical grouting water plugging-reinforcing material disclosed by the invention does not contain benzene, xylene, acetone and other solvents and does not influence the water quality after curing, and the solid content is 100%, thereby being environment-friendly and pollution-free; and when in use, the reaction speed of the double components is very high, the reaction starts after 20 seconds and basically finishes after 90 seconds, the reaction time is adjustable according to the engineering demands, and thus, the polyurethane chemical grouting water plugging-reinforcing material can effectively and quickly solve the problems of water leakage and water inflow of mines.

Description

technical field [0001] The invention relates to a chemical grouting material, in particular to a high-performance polyurethane grouting water blocking-reinforcing material, which belongs to the chemical industry field. Background technique [0002] With the rapid development of my country's economy, the shortage of energy has prompted the vigorous development of the coal mine mining industry. A number of large-scale, high-yield and efficient mines have been put into production. The deepening of traditional coal mines has increased the production safety and high-efficiency production guarantee. The problems are very serious, such as large fault zones, broken and loose surrounding rock areas, fracture development zones, roof caving under increased dynamic pressure, and groundwater damage, which directly affect the safety and efficient production of coal mines. And with the rapid development of national infrastructure, the construction of various railway tunnels, highway tunnels...
