Problems solved by technology

[0003] With the continuous improvement of people's living standards, people have put forward higher requirements for the quality of construction projects and their waterproof and leak-proof. However, basement leakage has always been a high-incidence area of ​​leakage, especially the construction joints at the root of the wall, stair landing steps and In addition to the waterproof design scheme and waterproof construction, the part of the wall-piercing pipe is more caused by the subsidence of the backfill soil caused by the brutal backfill. The lateral friction force tore the weakly bonded waterproof layer, destroying the integrity of the waterproof , the construction site is commonly known as "pants off", because the side wall waterproofing scheme design does not have system schemes recognized by the industry such as the basement floor "pre-paved reactive adhesive system" and the basement roof "non-curing composite system", and some are only some materials Superimposed and combined, can not meet the ideal waterproof needs

Abstract

The invention discloses a water-based rubber asphalt waterproof coating which is prepared from the following raw materials in parts by weight: 30-60 parts of emulsion with the solid content of not less than 50%, 5-10 parts of liquid rubber asphalt emulsion with the solid content of not less than 50%, 40-60 parts of inorganic filler, 0.1-1 part of defoaming agent, 0.1-1 part of thickening agent, 0.1-1 part of wetting dispersant and 0.1-1 part of pigment assistant; wherein the emulsion is one or more of acrylate emulsion, vinyl acetate-ethylene copolymer emulsion and styrene-acrylic emulsion. The coating is convenient to construct and high in facade slippage resistance, and has a good waterproof effect in the side wall composite use process with an asphalt coiled material.

Description

technical field [0001] The invention relates to a waterproof coating, in particular to a water-based rubber asphalt waterproof coating. [0002] technical background [0003] With the continuous improvement of people's living standards, people have put forward higher requirements for the quality of construction projects and their waterproof and leak-proof. However, basement leakage has always been a high-incidence area of ​​leakage, especially the construction joints at the root of the wall, stair landing steps and In addition to the waterproof design scheme and waterproof construction, the part of the wall-piercing pipe is more caused by the subsidence of the backfill soil caused by the brutal backfill. The lateral friction force tore the weakly bonded waterproof layer, destroying the integrity of the waterproof , the construction site is commonly known as "pants off", because the side wall waterproofing scheme design does not have system schemes recognized by the industry s...
