Problems solved by technology

Waterproof coiled material is mainly used for building walls, roofs, etc. to resist external rainwater and groundwater seepage. Seams are not tight, easy to leak
Although the acrylate waterproof coating overcomes the limitations of a single polymer emulsion, the comprehensive properties of the coating film such as adhesion, elasticity, and water resistance can be comprehensively improved, and the coating film has good hydrophobicity after drying, but Its poor stain resistance and low hardness limit its application range in concrete waterproofing projects

Abstract

The invention discloses a modified acrylic ester waterproof coating. The waterproof coating is prepared from components in parts by weight as follows: 35-55 parts of an acrylic ester modified compound emulsion, 2-6 parts of a fluorocarbon surfactant, 2-8 parts of nano-modified materials, 20-30 parts of pigment filler, 0.1-0.3 parts of a humidity controlling agent, 0.3-0.7 parts of a dispersing agent, 0.2-0.4 parts of a defoaming agent, 1-2 parts of a coalescing agent, 0.5-0.7 parts of a thickening agent, 0.2-0.6 parts of an antioxidant, 0.4-0.8 parts of glass fiber, 0.1-0.3 parts of a preservative sterilizing agent, 0.4-0.6 parts of emulsified paraffin and 25-35 parts of water. The waterproof coating adopts a reasonable formula, has good stain resistance, high hardness and excellent overall performance and can be applied to waterproofing work of a roof, a basement, a toilet and the like.

Description

technical field [0001] The invention relates to a modified acrylate waterproof paint, which belongs to the technical field of concrete building waterproof materials. Background technique [0002] Concrete is one of the most used and versatile materials in modern architecture. This is because it not only has the characteristics of abundant raw materials, low price, and simple production process, but also has the advantages of high compressive strength, good durability, and a wide range of strength grades. Gradually, concrete was placed with great expectations. But in fact, volume shrinkage and deformation will occur during the hydration and hardening process of concrete, and at the same time, the internal tensile stress of concrete will be greater than the tensile strength, resulting in cracking and water seepage, which will seriously affect the durability of concrete, the stability of steel bars and the safety of buildings. sex. Therefore, solving the problems of cracking...
