Abstract

The invention discloses a waterproof paint for a building material, belonging to the technical field of building materials. The waterproof paint comprises the following raw materials by weight: 50 to 60 parts of epoxy resin emulsion, 3 to 10 parts of polyacrylate, 1 to 5 parts of a dispersing agent, 40 to 45 parts of cement, 8 to 12 parts of talcum powder, 0.2 to 5 parts of a dehydrating agent, 0.5 to 2 parts of a silane coupling agent, 0.2 to 0.4 part of an antiseptic, 1 to 3 parts of a polycarboxylate water reducer, 5 to 10 parts of pigment, 0 to 2 parts of a pH value regulating agent, 3 to 6 parts of a plasticizer, 0 to 2 parts of an antifoaming agent and 0.8 to 1 part of a liquid aromatic. The invention also discloses a preparation method for the waterproof paint for the building material. The waterproof paint provided by the invention has good corrosion resistance, durability, impermeability, compactness and high adhesion stress; and the preparation method is simple and reliable.

Description

technical field [0001] The invention relates to the technical field of building materials, in particular to a waterproof coating for building materials and a preparation method thereof. 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 coating, it is generally diluted with organic solvents such as toluene and xylene, so it also contains toxicity; the other type is polymer cement-based waterproof coating. It is composed of a variety of water-based polymer emulsions and high-quality cement mixed with various additives. The flexibility of the polymer (resin) and the rigidity o...
