Abstract

The invention discloses an environment-friendly type polymer emulsion building waterproof coating which comprises the following components in parts by weight: 80-100 parts of polymer emulsion, 1-3 parts of defoaming agent, 60-85 parts of packing, 5-10 parts of photocatalyst and 5-15 parts of kieselguhr. The environment-friendly type polymer emulsion building waterproof coating disclosed by the invention is not only excellent in thick coating capability, waterproof effect and anti-cracking effect, but also free of formaldehyde or VOC, and can purify air.

Description

technical field [0001] The invention relates to the field of waterproof materials for civil buildings or other common structures. Background technique [0002] The polymer emulsion architectural waterproof coating is a volatile film-forming waterproof coating made of polymer emulsion as the main film-forming material, adding various surfactants to stabilize the filling powder. Harmful health substances such as plasticizers, APEOs, and various surfactants will slowly invade the living environment, causing long-term harm to the living environment. However, this kind of coating does not add plasticizers, surfactants, film-forming agents, dispersants and other auxiliary materials, and the elasticity index and stability of the product cannot be guaranteed. SUMMARY OF THE INVENTION [0003] In view of the defects of the prior art, especially the defects of the existing waterproof coatings using photocatalysts, the applicant has improved the composition of the coatings. By selec...
