AI Technical Summary
Technical Problem
Existing acrylate grouting materials are prone to water loss and shrinkage in dry environments, affecting the blocking effect of leakage water channels, and secondary leakage is prone to occur under vibration or load disturbance.
Method used
Using composite acrylate grouting materials, a natural composite hydrosol formed by adding carrageenan and konjac gel is combined with the acrylate main agent, accelerator and crosslinking agent to form a gel with high strength and good water retention.
Benefits of technology
It realizes rapid gelation and expansion in a water environment to block the seepage channel, reducing the risk of re-leakage, and has good toughness and compressive strength, which is suitable for water leakage treatment and repair of deformation joints.

Abstract
The invention discloses a composite acrylate grouting material which comprises a first component, a second component and a third component, the first component comprises the following components in parts by weight: 95-98 parts of an acrylate main agent, 1-3 parts of an accelerant and 1-2 parts of a cross-linking agent; the second component is prepared from 97 to 99 parts of water and 1 to 3 parts of initiator; the third component comprises natural composite hydrosol formed by carrageenan and / or konjac glucomannan, and the natural composite hydrosol accounts for 0.5%-2% of the total mass of the first component and the second component. The composite acrylate grouting material disclosed by the invention is good in water expansibility, small in water loss shrinkage rate, high in water retention rate, high in compressive strength and relatively good in toughness, and can quickly gel and expand to block a water seepage channel in a water environment, so that the risk of re-seepage is greatly reduced.
