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 novel waterproof acrylate coating. The novel waterproof acrylate coating is prepared from the following components in parts by weight: 30 to 50 parts of an acrylate modified composite emulsion, 2 to 4 parts of a fluorocarbon surfactant, 2 to 6 parts of a nano modified material, 20 to 30 parts of pigment and filler, 0.1 to 0.5 part of a humidity-controlling agent, 0.5 to 0.7 part of a dispersing agent, 0.3 to 0.5 part of an antifoaming agent, 1 to 2 parts of a coalescing agent, 0.6 to 0.8 part of a thickening agent, 0.2 to 0.8 part of an antioxidant, 0.3 to 0.7 part of glass fiber, 0.2 to 0.4 part of an anticorrosion and bactericidal agent, 0.2 to 0.6 part of emulsified paraffin and 20 to 30 parts of water. The novel waterproof acrylate coating disclosed by the invention is reasonable in formula, good in stain resistance, high in hardness and good in overall performance, and can be applied to waterproof treatment of roofs, basements, bathrooms and the like.

Description

technical field [0001] The invention relates to a novel 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 an...
