Problems solved by technology

[0002] During construction in areas with high water level and soft soil, and after the building is completed and put into use, the substructure of the building is in the water medium, and cracks and water leakage often occur, which affect the normal use of the building and constitute a huge safety hazard
Traditional waterproof plugging materials include polyurethane, acrylic ester, and cement-based permeable crystals. Due to their material characteristics, these materials have the disadvantages of poor strength and durability, and can only play a short-term plugging effect without reinforcement. role, and the raw material production process is more toxic

Abstract

The invention discloses an underwater high polymer adhesive and a preparation method thereof. The adhesive is composed of a component A and a component B in a mass ratio of 3:1. The component A comprises, by weight: epoxy resin E44; polysulfide rubber JLY-121; ethanol; acetone; butyl glycidyl ether; and furfural. The component B comprises, by weight: dibutyl phthalate; 2, 4, 6, tris(dimethylaminomethyl)phenol; and modified ketimine. The underwater high polymer adhesive provided by the invention has the characteristics of no toxicity, low cost, high performance, high strength, and curing in water, etc., thus being a product in urgent need during waterproof and plugging construction of subway, tunnels and underground projects with water. The preparation method of the underwater high polymer adhesive provided by the invention is simple, and the production process is non-toxic.

Description

technical field [0001] The invention belongs to the technical field of building waterproofing, leak plugging and reinforcement, and in particular relates to a high-performance reinforcing material for waterproofing and leak plugging that can be constructed underwater. Background technique [0002] During construction in areas with high water level and soft soil, and after the building is completed and put into use, the substructure of the building is in the water medium, and cracks and water leakage often occur, which affect the normal use of the building and constitute a huge safety hazard. Traditional waterproof plugging materials include polyurethane, acrylic ester, and cement-based permeable crystals. Due to their material characteristics, these materials have the disadvantages of poor strength and durability, and can only play a short-term plugging effect without reinforcement. role, and the raw material production process is more toxic.
