Abstract

The invention discloses a GS acrylic resin grouting agent and a preparation method thereof. The GS acrylic resin grouting agent is composed of a component A and a component B in a mass ratio of (1-2): (1), the component A is prepared from the following raw materials in parts by weight: 600 to 800 parts of water, 50 to 150 parts of sodium hydroxide, 150 to 250 parts of acrylic acid, 10 to 50 parts of acrylamide and 15 to 30 parts of methylene bisacrylamide; and the component B comprises the following raw materials in parts by weight: 700-1000 parts of water and 50-100 parts of sodium persulfate. According to the invention, acrylic acid is used as a main material, acrylamide and methylene bisacrylamide are compounded for use, and sodium persulfate is used as an initiator; the prepared GS acrylic resin grouting agent has the effects of being long in timeliness, good in toughness, high in elasticity and large in expansibility; and the product can be independently used, can also be mixed with cement and other materials for use, and is relatively high in practicability.

Description

technical field [0001] The invention relates to the technical field of waterproofing and plugging of underground engineering, and more particularly relates to a GS acrylic resin grouting agent and a preparation method thereof. Background technique [0002] With the continuous growth of my country's economy, the continuous acceleration of urbanization, and more and more housing construction, people attach great importance to the utilization of underground space in buildings, and there are more and more underground engineering projects. However, in underground engineering, buildings are surrounded by groundwater for a long time. If there is no strict anti-leakage construction design scheme and construction process control, leakage accidents will easily occur, which will seriously affect the quality of the project, and at the same time reduce the strength and shorten the construction time. Use period. At present, the quality of anti-seepage construction of underground building...
