Title:
COATING LIQUID CONTAINING WATER ABSORPTION POLYMER AND COATING ARTICLE
Document Type and Number:
Japanese Patent JP2015221886
Kind Code:
A
Abstract:
PROBLEM TO BE SOLVED: To provide a coating liquid mainly containing a water absorption polymer by dispersing the water absorption polymer in water and a coating article coated by the same for overcoming inconvenience by limitation of applications because the water absorption polymer swells to be gel like or agar like by adding to water and loosing flowability and it cannot be made as a coating liquid.SOLUTION: There is provided a coating liquid manufactured by blending a water absorption monomer, an electrolyte, a fine powdery silica, a thickener and a polymer aqueous dispersion and a coating article coated the same. There is provided a coating liquid using, by weight part, 100 part of the water absorption monomer, 10 to 300 part of the electrolyte, 1 to 200 part of the fine powdery silica, 0.1 to 10.0 part of the thickener and 10 to 500 part, by solid content, of the polymer dispersion. There is provided a coating liquid where the water absorption polymer is a partial crosslinked body of sodium polyacrylate, the electrolyte is a neutral salt of an alkali earth metal, the thickener is high molecular weight carboxymethyl cellulose, polyvinyl alcohol or modified starch and the polymer dispersion is an ethylene-vinyl acetate copolymer.
