COMPOSITION FOR PAPER MANUFACTURING Russian patent published in 2008 - IPC D21H21/36 D21H21/16 D21H11/00 

FIELD: paper and pulp manufacturing.

SUBSTANCE: the present innovation deals with manufacturing paper being of high antimicrobial and fungicidal activity and could be applied for manufacturing paper being resistant to contamination, of high physico-mechanical properties and applied for manufacturing banknotes, bonds, shares and others. The suggested composition includes a filamentous constituent, a filler, a gluing constituent, a biocidal additive as synergistic mixture of polyhexamethylene guanidine and sodium salt of benzoic acid at the ratio being (10-1):(1-10), correspondingly, a moisture-resistant additive, a binding agent and water. Moisture-resistant additive is being epichlorohydrin or urea-formaldehyde resin. Binding agent is being formalin or ammonium salt of titanium chelate and lactic acid. Gluing constituent additionally contains polyvinyl alcohol or sodium salt of carboxymethyl cellulose. The innovation enables to increase antimicrobial and fungicidal activity of the composition mentioned, simplify its application and, also, increases physico-mechanical properties, abrasion resistance and resistance to contamination of the obtained paper.

EFFECT: higher efficiency of manufacturing.
