Problems solved by technology

There is also a silicone waterproofing agent, which requires a large amount of use and complicated construction.
The current waterproofing agents all have the characteristics of poor comprehensive properties. After coating, it is difficult to guarantee the construction quality, and the service life is short. Soon after coating, water leakage and penetration will occur.
[0004] However, the interface agent used in the market often achieves only the effect of the interface and has no waterproof function, which limits its scope of use.
To make the interface agent have a waterproof effect, it is often necessary to add an additional waterproof process, which further increases the amount of work

Abstract

The invention provides an interface waterproofing agent which comprises a component A and a component B, wherein the component A is liquid, and the component B is powder; the component A and the component B comprise the following components respectively in part by mass: the component A comprises 370 to 450 parts of waterproof glue liquid, 1 to 2 parts of defoaming agent, 1 to 2 part of preservative, 1 to 2 parts of wetting agent and 550 to 630 parts of water; and the component B comprises 800 to 1000 parts of cement, 500 to 600 parts of sand, 500 to 600 parts of ground calcium carbonate and 10 to 20 parts of crylic acid glue powder. The component A and the component B are prepared by mixing the components through the conventional method and are directly brushed on construction parts after being evenly mixed mechanically or manually by the ratio of 1: 2 in use. The interface waterproofing agent synthesizes the water resistance and the interface effect as a whole, so that the scene construction procedures are reduced, the use is convenient, and the manpower and material costs are reduced.

Description

technical field [0001] The invention relates to building waterproof materials, in particular to an interface waterproofing agent. Background technique [0002] Waterproof technology is a specialized technology to ensure project quality and avoid water erosion hazards, and it occupies an important position in project construction. In daily life, ground leakage in houses, leakage and humidity in hotel toilets, leakage and humidity in underground projects are common problems. Water is a polar substance with a surface tension of about 72mN / m. It has strong diffusivity and can wet a variety of substances. It can not only flow through large void channels under gravity, but also flow in all directions through capillary pores. Therefore, an effective way to solve engineering leakage and moisture problems is to develop and apply waterproof materials. [0003] At present, the known waterproofing agent has poor effect, complicated construction, and easy cracking and falling off. The...
