A kind of ungauged regions epoxy grouting material and preparation method thereof

The present invention relates to a kind of ungauged regions epoxy grouting material and preparation method thereof, described material and preparation method thereof comprises: (1), preparation low-viscosity epoxy resin and modified firming agent; (2), by low-viscosity epoxy resin, reactive thinner, low-viscosity toughner stirs in proportion until dispersion of materials is even; (3) add tensio-active agent, in the material and dispersed with stirring, then add Expanding Monomer and hydroxyl terminated butyl nitrile (HTBN) rubber and dispersed with stirring, heat gradually to 60 DEG C and disperse, after being cooled to room temperature, adding silane coupling agent and dispersed with stirring; (4) modified firming agent dispersed with stirring, is added.Beneficial effect of the present invention is: a kind of ungauged regions epoxy grouting material provided by the invention has abandoned the larger furfural-acetone system of toxicity, adopt self-control low-viscosity epoxy resin, add reactive thinner, the efficient material such as toughner and tensio-active agent reduces cure shrinkage, and ensure that lower initial viscosity, reduce harm to human body and environment etc.
