Problems solved by technology

[0004] At present, although the existing waterproof glue has certain adhesive properties, its own impermeability and compressive properties are relatively poor.
Moreover, its heat resistance, low temperature resistance and aging resistance are relatively poor, which not only affects the quality of waterproof glue; but also shortens its service life

Abstract

The invention relates to the technical field of building adhesives, and concretely relates to an anti-seepage waterproof adhesive for leaking stoppage of a downstream face, and a preparation method thereof. The waterproof adhesive is prepared from, by weight, 40 to 60 parts of epoxy resin, 10 to 20 parts of trihydroxy polyether, 3 to 6 parts of butanediol diglycidyl ether, 6 to 10 parts of sodium silicate, 3 to 6 parts of 2, 6-di-tert-butyl-4-methylphenol, 3 to 5 parts of nano cerium oxide, 30 to 45 parts of superfine silica powder, 0.8 to 1.2 parts of sodium dodecyl benzene sulfonate, 4 to 7 parts of a functional aid, 2 to 5 parts of a thixotropic agent, 1.0 to 2.5 parts of a wetting agent, 0.8 to 1.5 parts of a de-foaming agent, 2.8 to 4.2 parts of an accelerant, 2.5 to 5.8 parts of a water removal agent and 1.2 to 2.0 parts of a penetrating agent. The waterproof adhesive prepared by the preparation method disclosed by the invention not only has good anti-permeability and anti-aging performance, but also has super-strong compression resistance, and further has good heat resistance and low-temperature toughness; and the quality of the waterproof adhesive product is effectively ensured.

Description

technical field [0001] The invention relates to the technical field of building adhesives, in particular to an anti-seepage waterproof adhesive used for blocking leakage on the backwater surface and a preparation method thereof. Background technique [0002] In recent years, no matter in technology, in theory or in the implementation of engineering technology, housing construction has made great progress on the previous basis. However, in recent years, various severe natural disasters have occurred repeatedly, and the quality of some housing construction itself is substandard, so water leakage always occurs in these housing constructions. The occurrence of this undesirable phenomenon seriously disturbs people's normal life. [0003] Waterproof glue is often used when repairing water seepage in houses. Waterproof glue has high flexibility, waterproof and moisture insulation, strong adhesion, strong crack resistance, strong air permeability and water impermeability, simple co...
