Abstract
The invention discloses a two-component high polymer material for back grouting diffusion of a steel panel and a preparation method of the material. The high polymer material comprises a component A and a component B, the component A comprises, by mass, 45% of polyol, 36% of a phosphorus-based flame retardant, 2% of an amine catalyst, 15% of a physical foaming agent, 1% of a silicon surfactant and1% of water; the component B is polymethylene polyphenyl isocyanate; and the component A and the component B are mixed according to the mass percentage content of 100: 100 to obtain the high polymermaterial. The high polymer material has an immediate leakage stopping effect on leakage water of a building structure, and can be widely applied to leakage stopping projects such as dams, subways, tunnels, culvert boxes, ground improvement, earthwork collapse, reservoirs, harbor engineering, top plates, cracks, construction joints, expansion joints, basement filamentous cracks and the like.
Description
technical field [0001] The invention relates to the technical field of high polymer materials, in particular to a two-component high polymer material used for back grouting and diffusion of steel panels and a preparation method thereof. [0002] technical background [0003] In recent years, my country's water conservancy infrastructure construction has made remarkable achievements. At present, the total length of embankments has been 410,000 kilometers, and there are more than 98,000 reservoirs of various types. They are an important part of my country's flood control and disaster reduction field. , The geological conditions are complex, and dangers occur frequently during the flood season. Similarly, among the built reservoirs, the risk rate reaches 57.1%, and most of the small and medium-sized dangerous reservoirs need anti-seepage reinforcement. Once these water conservancy facilities fail, it will have a major impact and seriously threaten the safety of people's lives a...
