Abstract

The invention provides an environment-friendly acrylate grouting material, as well as a preparation method and an application thereof. The material mainly comprises the following components in parts by weight: a main agent, namely 100 parts of methacrylic acid-beta-hydroxyethyl ester, a crosslinking agent which includes 5-30 parts of hydrophilic compound containing a diallyl ether functional group, 1-5 parts of initiator and 0.5-3 parts of accelerant, 0-20 parts of an adjuvant, and a solvent, namely 2-1,000 parts of water. The method comprises the following steps: firstly, mixing the main agent, the crosslinking agent, the accelerant, the adjuvant and a part of solvent evenly to form a solution A in use; then dissolving the initiator into a residual solvent to form a solution B; and finally mixing the solution A with the solution B evenly, and solidifying at room temperature. According to the grouting material disclosed by the invention, the technical problem that the existing organic grouting material cannot be grouted once after being mixed with an inorganic grouting material, and the technical problem that the existing grouting material has poor durability, low strength, poor water solubility, low water expansion rate and high toxicity are solved.

Description

technical field [0001] The invention relates to a grouting material for seepage prevention and plugging in geotechnical engineering, in particular to an environmentally friendly acrylic grouting material suitable for seepage prevention and reinforcement of foundation treatment engineering, water stop and reinforcement of deformation joint leakage and Its preparation method and application. Background technique [0002] In the anti-seepage and reinforcement treatment of foundation treatment engineering, acrylate grouting materials and modified epoxy resin grouting materials are often used as grouting materials for anti-seepage and reinforcement treatment. However, the price of organic grouting materials is relatively high, resulting in high construction costs. For this reason, the construction unit hopes to mix organic grouting materials and conventional inorganic grouting materials such as cement slurry, clay cement slurry, bentonite cement slurry, etc. for grouting, and us...
