WATER-SOLUBLE MELT ADHESIVE, USE THEREOF, METHOD OF PRODUCING MULTILAYER MATERIAL, METHOD OF PRODUCING PAPER, WHICH IS ADHESIVE WHEN WET AND METHOD OF PRODUCING MULTILAYER TEXTILE MATERIAL Russian patent published in 2009 - IPC C09J131/00 C08L31/00 C09J175/04 C08L75/04 C09J133/02 

FIELD: textiles; paper.

SUBSTANCE: invention relates to producing water-soluble melt adhesive, which can be widely used in cardboard and paper industry for gluing and laminating cardboard, as well as for making joints of not less than two layers of paper, used for making toilet paper. The water-soluble melt adhesive contains 40-70 wt.% of not less than one homopolymer or copolymer with free carboxylate groups based on monomers with unsaturated ethylene bonds (component A), 15-45 wt % of not less than one water-soluble or polyurethane dispersed in water (component B), 12-35 wt % of not less than one alkanolamine (component C) and 0-20 wt % target additives.

EFFECT: obtained melt adhesives have high viscosity, elasticity and high strength of adhesive bonds on packages at low temperatures during storage of products, and at high temperatures the adhesive does not soften and does not flow.
