Problems solved by technology

However, since the expansion of this material is caused by the foaming of the water reaction, when the water content of the structural layer injected with the slurry is reduced or even after the space filled with foam is dried, this foamed gel-like consolidated body material will gradually form. A certain amount of shrinkage will cause subtle changes to the original good waterproof effect. After a certain period of time (about one year), some parts will often leak again.
Therefore, the water-soluble polyurethane grouting material does not have good waterproof durability for the waterproof plugging of the leaking part where the upstream surface is not long-term water-containing
Compared with water-soluble polyurethane grouting fluid, another grouting material used for waterproofing and plugging is oil-soluble polyurethane grouting fluid. Although this material generally does not shrink or re-expand due to changes in the surrounding environment after reaction foaming, it does This kind of material lacks flexibility after foaming, and the stress caused by the deformation of the surrounding structure of the foam is easy to tear the foam used for waterproofing, so that the leaking weak parts will leak again

Abstract

The invention relates to a new material for water-proofing and leakage-stopping grouting, which belongs to the technical field of new materials and is particularly suitable to be used in grouting for stopping the leakage of leakage water in a structure of a concrete building. The new material for waterproof and leakage-stopping grouting of the invention is prepared by mixing a waterproof paint and an assistant, and is characterized in that: the waterproof paint is emulsified polymer building waterproof paint; and the assistant is prepared by mixing solvent-free polyurethane and polyurethane curing agent, wherein based on the total amount of 100 part of the emulsified polymer building waterproof paint, the solvent-free polyurethane is 8 to 20 parts and the polyurethane curing agent is 4 to 10 parts. Compared with the prior art, the new material has the advantages that: the mixed materials can gel through cure reaction within a certain time period to proof water and stop leakage; and the cured material has stable performance, high acid, alkali and aging resistance and high durability.

Description

technical field [0001] The invention relates to a grouting, waterproof and leak-stopping material belonging to the technical field of materials, and is a material particularly suitable for grouting and plugging leaking water in concrete building structures. technical background [0002] In the prior art, the leaking water of concrete building structures is used for grouting and plugging materials. In the invention patent publication number: CN1924534, a new waterproof plugging method is proposed in "Methods for Detection and Plugging of Water Leakage Sources in Concrete Buildings" Leakage method, that is: through the grouting hole, the water-soluble polyurethane plugging agent added with the grouting liquid hardening regulator is injected through the grouting hole, so that the grout passes through the roof to form a layer between the roof waterproof material and the roof slab. New connected waterproofing. Water-soluble polyurethane chemical grouting material is a polymer gr...
