Problems solved by technology

The other is to use polyurethane epoxy and add a large amount of furfural and acetone diluent. These two methods can form a grouting material with certain elasticity, but there are disadvantages such as high volatility and not environmental protection.
The use of long-chain reactive dilution systems and flexible epoxy resins to study environmentally friendly elastic epoxy grouting materials with good groutability has not been reported at home and abroad.

Abstract

The present invention relates to elastic high-strength epoxy grouting material and its preparation. The elastic high-strength epoxy grouting material features its material composition comprising epoxy resin in 100 weight portions, long chain active diluent in 50-150 weight portions, curing agent in 10-100 weight portions and silane coupler 0.5-10 weight portions. The epoxy resin contains flexible epoxy resin in 20-60 weight portions. The present invention has the features of good grouting performance, high elasticity and no toxicity.

Description

technical field [0001] The invention relates to an epoxy grouting material and its preparation, which is widely used in anti-seepage reinforcement and reinforcement of active cracks in hydraulic constructions, expressways, bridges, subways, industrial and civil constructions and other projects. Background technique [0002] Epoxy grouting is to use epoxy resin as the main agent, add a certain amount of diluent and curing agent to prepare epoxy grouting grout, and then pour it into the formation cracks and concrete cracks with grouting equipment under certain process conditions In order to achieve anti-seepage and reinforcement of the poured body, so as to ensure the safe operation of the building. [0003] At present, most of the commonly used epoxy grouting materials in China are high-strength grouting materials. The epoxy grouting materials of this system are mainly used for crack and bedrock reinforcement. They have been widely used in my country and solved many engineeri...
