The present invention provides a polyacrylic acid copolymer emulsion, an organic-inorganic composite waterproof coating, preparation method thereof, and a waterproof coiled material. It belongs to the technical field of waterproof coiled material, and can solve the problem that the granules dropping out from the prior waterproof membrane easily. The organic-inorganic composite waterproof coating according the invention is prepared by the way of compositing organic granules and inorganic granules, wherein the organic coating locks the inorganic granules, and prevents the inorganic granules from dropping out. Some exposed inorganic granules take part in the cement hydration reactive, and increase the bonding strength with the post-poured concrete. Furthermore, the organic-inorganic composite waterproof coating according the invention does not need a buttering. It can reduce waste with omitting an adhesive-resist insulation membrane or paper. The organic-inorganic composite waterproof coating according the invention is used as a macromolecule self-adhesive film of waterproof coiled material, and can permit the coiled material exposing appreciably before pouring concrete, while provide a non-adhesive surface for the worker to walk. Experiments proof that the peeling strength of the organic-inorganic composite waterproof coating according the invention is above 2.0 N/mm after 8 weeks by placing outdoor. |
