Abstract

The invention provides an environmentally-friendly flame-retardant polymer cement waterproof coating. The coating comprises a liquid material and a powder material. A weight ratio of the liquid material to the powder material is (1 to 0.8) to (1 to 1.5). The liquid material comprises the following components in parts by weight: 65-85 parts of ethylene-vinyl acetate emulsion, 0.1-0.7 parts of an emulsifier, 1-17 parts of a plasticizer, 0.3-0.7 parts of a defoamer, 0.4-0.6 parts of a dispersant, 10-15 parts of water and 0.1-0.4 parts of a preservative. The powder material comprises the following components in parts by weight: 25-35 parts of cement, 20-30 parts of heavy calcium carbonate, 20-30 parts of quartz powder, 5-10 parts of polytetrafluoroethylene micropowder, 5-10 parts of micro-capsulated red phosphorus and 0.1-0.5 parts of a water reducer. The waterproof coating is environmentally-friendly; no organic matters are volatilized; and the waterproof coating is a nonflammable material.

Description

technical field [0001] The invention relates to a waterproof coating, in particular to an environment-friendly flame-retardant polymer cement waterproof coating, which belongs to the field of architectural waterproof coatings. Background technique [0002] With the development of society, people's quality of life is gradually improving, and people's requirements for architectural quality are getting higher and higher. In the past, we developed in an extensive way, with profit first, and shoddy construction, which caused a great impact on the environment. At the same time, it also buried a lot of safety hazards in terms of the quality of the building. [0003] Waterproofing is indispensable for construction engineering, but in the initial stage of the industry, due to the low level of the industry as a whole, various low-end waterproof materials are widely used, which has a great impact on our body while protecting the safety of the building. influences. For example, the as...
