Problems solved by technology

However, the traditional organic system epoxy resin plugging materials are all cured by phenalkamine, which leads to poor elasticity of the consolidated body, which cannot buffer the defects caused by geological factors, thermal expansion and contraction at the same time. Crack expansion, displacement, etc., can not achieve the ideal plugging effect

Abstract

The invention provides a high-elasticity modified epoxy resin grouting material for stopping leakage and a preparation method of the high-elasticity modified epoxy resin grouting material. The material is mainly prepared from a component A and a component B; the component A is prepared from the following raw materials in parts by mass: 50 to 100 parts of bisphenol-A epoxy resin, 10 to 20 parts ofpolyfunctional epoxy resin, 10 to 50 parts of nylon modified bisphenol-A epoxy resin, 5 to 10 parts of core-shell rubber and 5 to 50 parts of reactive diluent; the component B is mainly prepared fromthe following raw materials in parts by mass: 10 to 100 parts of phenolic amine curing agent, 0 to 3 parts of silane coupling agent and 0 to 3 parts of curing accelerator. According to the application, the polyfunctional epoxy resin, the nylon modified bisphenol-A epoxy resin and the core-shell rubber are introduced into the component A of two-component bisphenol-A epoxy resin leakage stopping material and are synergized with the bisphenol-A epoxy resin to obtain the component A with a specific formula. The component A can be mixed with the component B containing the phenolic amine curing agent to form a high-elasticity solid structure which realizes an excellent waterproof leakage stopping effect.

Description

Technical field [0001] The invention relates to the field of building materials, in particular to a modified epoxy resin grouting material for high elasticity plugging and a preparation method thereof. Background technique [0002] In recent years, the country has invested heavily in infrastructure, and the construction of buildings, rail transit, roads, and tunnels has also developed by leaps and bounds. This will inevitably be accompanied by the continuous improvement of the standards of infrastructure construction and the continuous improvement of technical requirements. Correspondingly, the technical standards of construction materials and maintenance materials have been continuously improved. [0003] At present, when water leakage occurs in buildings, rail transit, highways, tunnels, etc., polymer cement, acrylate, acrylic, polyurethane, etc. are mostly used as waterproof plugging materials. The plugging principle of these materials is that the materials themselves have a cer...
