Description

technical field [0001] The invention relates to the field of building materials, in particular to a polymer cement waterproof coating. Background technique [0002] Polymer cement-based waterproof coating, also known as JS composite waterproof coating. The polymer cement-based waterproof coating is based on the loss of water from the organic polymer emulsion to form a cohesive and continuous elastic film layer. The cement absorbs the water in the emulsion and hardens. The flexible polymer and the hardened cement body penetrate each other and bond firmly Form a strong and elastic waterproof layer, the flexible polymer is filled in the gap of the hardened cement body, making the hardened cement body more dense and elastic, the coating film has better elongation, and the hardened cement body is filled in the polymer phase , so that it has better outdoor durability and better grass-roots adaptability. Therefore, it has certain rigidity and toughness, and has high adhesion, and...
