Problems solved by technology

[0002] Acrylate waterproof coating is a one-component water-based architectural waterproof coating made of acrylate emulsion as the main raw material, adding appropriate amount of high-quality fillers and additives. Because of its excellent weather resistance and ultraviolet resistance, it can There is basically no change in performance within the temperature range. The waterproof layer has both decoration and heat insulation effects. It is environmentally friendly, non-toxic, and easy to construct. It is suitable for waterproof and anti-seepage projects such as roofs, walls, toilets, and basements. It can also be used as Adhesives or exterior wall decorative coatings, but currently there are problems such as unsatisfactory mechanical properties and poor antistatic properties, which will cause electric shock and fire due to electrical insulation damage caused by coating failure and wall corrosion, which seriously limits the application of this type of coatings. Promotion and application; therefore, the use of a substance that can not only improve the mechanical properties of water-based acrylate waterproof coatings, but also improve its antistatic ability is a non-negligible method to solve the problems of water-based acrylate waterproof coatings
