Abstract

The invention relates to a cement-based grouting material and a preparation method thereof. The cement-based grouting material comprises a component A, a component B and a component C, wherein the component A comprises the following components by weight part: 80 to 90 parts of epoxy resin, 1 to 10 parts of diluents, 0 to 1 part of defoaming agent and 1 to 5 parts of coupling agent; the component B comprises a water-soluble amine curing agent with an emulsification function; the component C comprises the following components by weight part: 30 to 50 parts of cement, 2 to 4 parts of ultrafine mineral powder, 0 to 1 part of silica micropowder, 2 to 4 parts of expanding agent, 0 to 1 part of water-reducing agent and 40 to 60 parts of river sand; and the weight ratio among the component A, the component B and the component C is (60 to 100) : (90 to 150) : (400 to 800). Mechanical indexes, such as compressive strength, breaking strength and the like, of the cement-based water-soluble epoxy resin grouting material are far more excellent than those of the common cement grouting material.

Description

technical field [0001] The invention relates to a cement-based composite material, in particular to a cement-based water-based epoxy resin grouting material and a preparation method, application and application method thereof. Background technique [0002] Water-based epoxy resin is a new type of environmentally friendly and pollution-free product. It has emerged as a new material in developed countries in Europe and the United States. It has been introduced to the market as a substitute for solvent-based epoxy resin to improve the toxicity and pollution of solvent-based epoxy resin. and other defects. [0003] At present, the reinforced repair and waterproof materials modified by water-based epoxy resin to cement-based materials have been successfully marketed. Cement-based grouting materials have been widely used in secondary grouting of equipment foundations, anchoring of anchor bolts, reinforcement and repair of concrete structures and other engineering constructions. ...
