preparation example Construction

[0042] The second aspect of the present invention provides a method for preparing the high-energy inorganic plugging grouting material, the steps at least include:

[0043] (1) Add the water-soluble unsaturated compound into water and stir, and then add accelerator, polymer emulsion, and defoamer under stirring conditions to obtain component A;

[0044] (2) Mix the crosslinking agent, the initiator and the inorganic filler to obtain the B component.

Embodiment 1

[0047] A high-energy-gathering inorganic plugging grouting material, a high-energy-gathering inorganic plugging grouting material, includes A component and B component, and the weight ratio between the A component and the B component is 1:1. In terms of weight percentage, the raw materials of the A component include: 10% water-soluble unsaturated compound, 5.5% accelerator, 5% polymer emulsion, 0.3% defoamer, and water to make up the balance; The raw materials of component B include: 4.5% cross-linking agent, 2.5% initiator, and the rest inorganic filler.

[0048] The water-soluble unsaturated compound is a mixture of acrylamide and acrylic acid; the weight ratio of acrylamide and acrylic acid is 1.4:1. The acrylate is magnesium acrylate. The inorganic filler is magnesium oxide, and the magnesium oxide is purchased from Beijing Deke Daojin Technology Co., Ltd., and the model is DK-MgO-001. The polymer emulsion is styrene-acrylic emulsion, and the model is Changxing styrene-a...

Abstract

The invention relates to the technical field of leaking stoppage grouting materials, and provides a high-energy-gathering inorganic leaking stoppage grouting material which comprises a component A anda component B in a weight ratio of 1: (0.1-2). The component A is prepared from the following raw materials in percentage by weight: 5 to 15 percent of a water-soluble unsaturated compound, 1 to 10 percent of an accelerant, 1 to 10 percent of a polymer emulsion, 0.1 to 0.5 percent of a defoaming agent and the balance of wate, and the component B comprises the following raw materials in percentageby weight: 1-8% of a cross-linking agent, 0.5-5% of an initiator and the balance of an inorganic filler.

Description

technical field [0001] The present invention relates to the technical field of leak-stopping grouting materials, in particular to a high-energy inorganic leak-stopping grouting material and a preparation method thereof. Background technique [0002] During the long-term use of concrete buildings, there will be different degrees of damage, but most concrete buildings can still be used after reinforcement and repair, thus exerting huge economic benefits. Repair and reinforcement are of great significance. The grouting material is made of high-strength materials as aggregates, cement as a binder, and supplemented with high-fluidity, micro-expansion, anti-segregation and other substances. Add a certain amount of water at the construction site and mix well before using. The grouting material has the characteristics of good self-flow, fast hardening, early strength, high strength, no shrinkage, slight expansion, non-toxic, harmless, non-aging, no pollution to water quality and su...
