Problems solved by technology

[0004] However, with the uneven quality of real estate houses, cracks are prone to appear in kitchens, bathrooms, basements and other places, resulting in water seepage
Although the existing JS waterproof coatings on the market have a certain elongation rate, the surface of the coating film is prone to defects such as tiny cracks and pinholes, so that it cannot achieve the waterproof effect, and eventually leads to the failure of the waterproof project

Abstract

The invention discloses a polymer cement waterproof coating. The coating comprises a liquid ingredient and a powder ingredient. The liquid ingredient comprises a polymer emulsion, triethanolamine, a dispersant, an antiseptic, an antifoaming agent and the balance water. The powder ingredient comprises special cement, ultrafine slag, ultrafine steel slag, metakaolin, an antifoaming agent, water-soluble cellulose, acrylamide powder, bisacrylamide powder, instant sodium silicate, aluminum stearate and the balance heavy calcium carbonate of 400 meshes. The coating has excellent anti-sagging and anti-cracking performances, has a self-repair function, can form crystals in concrete and has a certain secondary anti-permeability.

Description

technical field [0001] The invention relates to the technical field of chemical coatings, in particular to a polymer cement waterproof coating. Background technique [0002] Polymer cement waterproof coating, also known as JS composite waterproof coating, is an organic liquid material composed of polyacrylate emulsion and various additives, and inorganic powder composed of light and heavy calcium carbonate and other inorganic fillers and various additives. It is a two-component, water-based architectural waterproof coating made of reasonable proportion and composite. [0003] Polymer cement waterproof coating is a green and environmentally friendly material. It does not pollute the environment, has stable performance, excellent aging resistance, and long waterproof life; it is safe to use, convenient to construct, and easy to operate. It can be directly applied on a wet base surface without clear water; bonding Strong strength, the bonding strength between the material and ...
