Abstract

The invention belongs to the technical field of a water blocking material and discloses a filler reaction type epoxy composite material as well as a preparation method and application thereof. The composite material is prepared from a component A and a component B, wherein the component A is prepared from the following components in parts by weight: 10 to 70 parts of epoxy resin, 5 to 40 parts of an activating type reactive solvent, 0 to 30 parts of an enhanced type reactive solvent, 10 to 65 parts of reactive fillers, 0 to 5 parts of an interface enhancing agent and 0 to 5 parts of an interface activating agent; the component B is prepared from the following components in parts by weight: 5 to 85 parts of a function curing agent, 0 to 40 parts of a curing regulating agent, 5 to 85 parts of a double-function curing agent and 0 to 30 parts of a curing accelerant. With the adoption of the composite material, the effect of rapidly blocking water can be realized, and the disadvantages that the curing speed of the epoxy material in water is slow and the epoxy material is difficult to cure are avoided; the composite material has high mechanical strength, good durability and low-temperature resistance; the filler reaction type epoxy composite material has rapid curing speed, high mechanical strength and low construction cost.

Description

technical field [0001] The invention belongs to the technical field of water blocking materials, relates to an epoxy composite material, in particular to a filler-reactive epoxy composite material and its preparation method and application. Background technique [0002] The variety and performance of grouting water blocking materials are directly related to the quality and cost of water blocking projects. Inorganic grouting and water blocking materials are widely used in many simple projects due to their low engineering cost. However, compared with polymer grouting and water blocking materials, although inorganic grouting and water blocking materials can temporarily block large The problem of water gushing construction, however, the size of the slurry material cannot be injected into small cracks, the interface with the concrete is poor, and it cannot effectively bond the old and new concrete. There are interface problems, and the problem of water leakage cannot be completel...
