Abstract

The invention belongs to the technical field of cement concrete crack repairing, and particularly relates to epoxy resin crack pouring adhesive for repairing cement concrete cracks and a preparation method of the epoxy resin crack pouring adhesive. According to the technical scheme, a component A comprises the following components in parts by weight: 20-25 parts of waterborne epoxy resin emulsion, 3-5 parts of waterborne polyurethane and 2-5 parts of an acrylate emulsion; a component B comprises the following components in parts by weight: 20-25 parts of a waterborne epoxy curing agent, 1-2 parts of talcum powder, 0.1-0.2 part of a silane coupling agent, 0.1-0.2 part of an ultraviolet light absorber, 22-24 parts of superfine cement, 10.7-12.3 parts of self-repairing microspheres, 1.0-1.2 parts of a cement expanding agent and 0.1 part of a defoaming agent, and the total parts by weight is 60; and a component C: 5-10 parts of water; and the self-repairing microspheres are composed of super absorbent resin wrapped by silicon resin, superfine cement and a silane coupling agent. The pouring adhesive is an organic/inorganic composite crack repairing material which is formed by compounding waterborne epoxy resin and superfine cement and has a self-repairing function.

Description

technical field [0001] The invention belongs to the technical field of repairing cement concrete cracks, and relates to an epoxy resin joint glue for repairing cement concrete cracks and a preparation method thereof. Background technique [0002] Cement concrete is composed of stone, sand, hydrate gel, and hydration crystals. The distribution of its various components is disordered, without any rules at all. During concrete mixing and construction, pores, capillary pores, dry shrinkage cracks, temperature shrinkage cracks, and carbonation shrinkage cracks will occur. During the pouring and vibrating process of concrete, after the slurry at the bottom leaks to the base layer, the cement slurry around the aggregate decreases, and the filling density decreases. At the same time, during the setting process of cement concrete, the occurrence of bleeding causes more water to accumulate around the coarse aggregate to form a water film, which becomes the weakest area of ​​the ceme...
