The invention discloses heat-preservation and thermal-insulating water-based paint for a glass sliding door. The water-based paint is prepared from the following raw materials in parts by weight: 48-53 parts of waterborne
polyurethane resin, 16-19 parts of waterborne hydroxyl
acrylic acid, 0.2-0.4 part of
polypropylene oxide glyceryl
ether, 1-3 parts of
tripropylene glycol monobutyl
ether, 0.3-0.6 part of alkylol amine
titanate, 7-10 parts of modified pure acrylic
emulsion, 0.2-0.5 part of polyether modified organo-polysiloxane, 0.2-0.4 part of dimethicone, 0.2-0.4 part of an
accelerant TMTM, 0.3-0.6 part of butyl
glycidyl ether, 0.3-0.6 part of
guar gum, 0.3-0.5 part of diacetone-acryloamide, 0.4-0.9 part of
zeolite powder, 1-2 parts of
pigment, 1-3 parts of hollow glass microspheres, 2-3 parts of silica
sol and 12-16 parts of deionized water. Due to adoption of the silica
sol in the water-based glass paint disclosed by the invention, the
hardness of a paint film is improved, and the paint film is not easy to peel off and is smooth and flat; due to adoption of the hollow glass microspheres, the heat preservation and
thermal insulation effects are achieved, and the cost is lowered; due to adoption of the modified pure acrylic
emulsion, properties such as the flouring resistance, the bactericidal activity, the scrubbing resistance and the
weather resistance of the water-based paint are improved; the water-based paint is high in practicability and applicable to popularization.
