Abstract

The invention provides an acrylate grouting liquid composed of a liquid A and a liquid B, which both contain acrylate as main ingredient. The formulation and weight proportions of the liquids A and B are as follows: liquid A: acrylate aqueous solution 40-50 parts, acrylic ester cross-linking agent 5-7 parts, accelerator 0.5-5 parts, alkali metal hydroxide additive 0.4-0.5 parts, and water 1.5-3 parts; liquid B: initiator 0.3-0.6 parts, alkali metal hydroxide additive 1-1.5 parts and water 40-50 parts. The liquids A and B are prepared before use, and mixed in the field at equal volume under room temperature to form a gel. In the invention, the acrylic ester is used as cross-linking agent so that the grouting liquid is free of amido groups and doesn't cause environmental pollution; and the alkali metal hydroxide is added so that the grouting liquid exhibits certain expandability in water and exhibits good anti-seepage effect.

Description

technical field [0001] The invention relates to a grouting material for building anti-seepage and plugging, in particular to an organic grouting material and a preparation method thereof. Background technique [0002] Acrylate grout for soil stabilization began in the 1940s with the use of calcium acrylate. Because acrylic acid could not be mass-produced at that time and acrylamide chemical grouting materials appeared in the 1950s, the research, development and application of acrylate grouting materials progressed slowly. In 1974, after the application of acrylamide chemical grouting materials in Japan caused environmental pollution, acrylate grouting materials received people's attention. In 1980, the United States developed the AC-400 acrylate chemical grouting material, the toxicity of the aqueous solution of the acrylate monomer mixture with a solid content of 38-42%, oral LD ​​in rats 50 Close to 5000 mg / kg, classified according to toxicity, close to the actual non-to...
