Problems solved by technology

[0002] Polymer emulsion architectural waterproof coating is a volatile film-forming waterproof coating made of polymer emulsion as the main film-forming substance and adding various surfactants to stabilize filling powder. Hazardous substances such as plasticizers, APE0, 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 auxiliary materials such as plasticizers, surfactants, film-forming agents, and dispersants, and the elasticity and stability of the product cannot be guaranteed.

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] Polymer emulsion architectural waterproof coating is a volatile film-forming waterproof coating made of polymer emulsion as the main film-forming substance and adding various surfactants to stabilize filling powder. Hazardous substances such as plasticizers, APE0, and various surfactants will slowly invade the living environment, causing long-term harm to the living environment. However, this coating does not add plasticizers, surfactants, film-forming agents, dispersants and other auxiliary materials, and the elasticity and stability of the product cannot be guaranteed. Contents 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, and realized the powder fillers...
