Polyacrylic acid copolymer emulsion, organic-inorganic composite waterproof coating, preparation method thereof and waterproof coiled material

An organic-inorganic composite waterproof coating, comprising a pressure-sensitive adhesive layer composed of a pressure-sensitive adhesive, an inorganic particle layer composed of inorganic particles, and a polymer layer, wherein the three layers are formed on a substrate sequentially from a bottom to a surface,

• wherein the polymer layer is formed by solidifying a polyacrylic acid copolymer emulsion, and the polyacrylic acid copolymer emulsion comprises, in parts by weight, components of:
• 19 to 26 parts of water, 0.5 to 5 parts of a solubilizer, 0.1 to 0.5 part of a dispersant, 0.1 to 0.5 part of a wetting agent, 28 to 30 parts of an acrylic emulsion, 0.1 to 1 part of a film-forming additive, 0.2 to 0.3 part of a preservative, 0.5 to 0.6 part of a silane coupling agent, 0.5 to 0.6 part of an ultraviolet absorbent, 40 to 45 parts of a pigment, 0.1 to 0.5 part of an antimildew agent, 0.1 to 0.2 part of a defoamer, and 0.1 to 0.8 part of a leveling agent.
