The present invention provides an organic-inorganic hybrid polymer hydrogel, a preparation method thereof and an exterior wall thermal insulation mid-coat. The formula of the exterior wall thermal insulation mid-coat no longer uses inorganic silica aerogel and organic film-forming substances (usually polymer acrylic emulsion / resin) alone, but hybridizes the two into an organic-inorganic hybrid dispersion (i.e., the organic-inorganic hybrid polymer hydrogel). When added to the coating, the dispersion effect and production efficiency can be greatly improved, and the problems that may arise from mixing silica aerogel and polymer emulsion / resin in coating production, such as coating agglomeration, excessive viscosity, and post-thickness, etc., are avoided.

The present invention provides a coating composition containing an acrylic resin (1), an acrylic ester compound (2), and a quaternary ammonium compound (3), and containing, as monomer components constituting the acrylic resin (1): 5-50 mass% of a [beta]-diketone group-containing monomer (A); 0.1 to 0.8 mass% of a carboxyl group-containing monomer (B); and 49.5-94.5 mass% of a monomer (C) other than the monomer (A) and the monomer (B), wherein the monomer (C) does not contain all functional groups among a hydroxyl group, a nitrile group and an amide group, and the glass transition temperature of a homopolymer is 60 DEG C or higher. The coating composition can obtain a cured product having excellent base material adhesiveness, chemical reagent resistance and solvent resistance without using an isocyanate-based curing agent, and thus can be used in the fields requiring high durability and safety, such as automotive interior and exterior decoration, home appliances, building material-oriented coatings, coating agents for films, and the like.
