WATER-BASED RESIN EMULSION COMPOSITION FOR FOAMED WALLPAPER

Title:

WATER-BASED RESIN EMULSION COMPOSITION FOR FOAMED WALLPAPER

Document Type and Number:

Japanese Patent JP2004189912

Kind Code:

A

Abstract:

To provide water-based resin emulsion for foamed wall paper having adequate foaming property, excellent in surface strength and cold resistance, using a heat expansion type foaming agent free from occurrence of a harmful material such as formaldehyde and excellent in safety and being suitably useable for foamed wall paper.

The water-based resin emulsion composition comprises an ethylene-vinyl acetate-polyfunctional monomer copolymer emulsion having +10 to -15°C glass transition temperature (Tg) and obtained by using the polyfunctional monomer in an amount of 0.05-0.2pts.wt. based on 100pts.wt. vinyl acetate and using a hydroxyethyl cellulose and a polyoxyethylene nonionic surfactant having 5-20 HLB as emulsifying agents in emulsion polymerization of the copolymer.
