Abstract

The invention provides polymer emulsion architectural waterproof coating modified by emulsified asphalt. The polymer emulsion architectural waterproof coating is characterized by being prepared from the following raw materials in parts by weight: 20 to 45 parts of polymer emulsion, 0.2 to 0.5 part of dispersing agent, 0.2 to 0.5 part of emulsifying agent, 0.3 to 0.6 part of defoaming agent, 0.2 to 0.4 part of sterilizing agent, 10 to 35 parts of the emulsified asphalt, 30 to 52 parts of powdery fillers and 7 to 15 parts of water. The polymer emulsion architectural waterproof coating disclosed by the invention has the advantages of good mechanical performance, good weather resistance, strong waterproof ability and acid-base corrosion resistance.

Description

technical field [0001] The invention relates to a building waterproof coating, in particular to a polymer emulsion building waterproof coating modified with emulsified asphalt and a preparation method thereof, belonging to the field of building waterproof coatings. Background technique [0002] There are two types of waterproof materials on the market: one is polyurethane waterproof coatings. Such materials are generally made of polyurethane and coal tar as raw materials. The tar gas it volatilizes is highly toxic and not easy to remove, so it was banned in China in 2000. The polyurethane waterproof coating that is still on sale uses asphalt instead of coal tar as a raw material. However, when using this kind of paint, it is generally diluted with organic solvents such as toluene and xylene, so it also contains toxicity. [0003] Another type is polymer cement-based waterproof coating. It is composed of a variety of water-based polymer emulsions and high-quality cement m...
