This invention discloses a frost-inhibitive paint with good water absorbency, which comprises: polyacrylic acid absorbent resin 20-40 parts, metal baking paint containing polyacrylic acid resin, amino alkyd resin or polyurethane 40-60 parts, NaCl or KCl crystal particles 20-40 parts, and solvent 20-40 parts. The solvent is cyclohexanone, gasoline, propylene glycol butyl ether, butyl acetate or butanone. The layer painted from the paint has a thickness of 0.06 mm, and an impact strength higher than 50 kg .cm/cm2. The paint has a more obvious frost-inhibitive effect when the humidity is 50%. |
