FIELD: paper industry.
SUBSTANCE: invention relates to novel aqueous dispersions of hydrophobic materials used in paper industry as gluing agents. Disclosed is an aqueous composition for gluing paper containing a hydrophobic gluing agent for paper, homogenised with aqueous solution of modified alkyl glycidyl ether of poly(aminoamide), having pH lower than 4.0, and where viscosity is not higher than about 400 cP after 4-week storage at 32 °C. Invention also discloses a method of preparing said composition and method of gluing paper using same.
EFFECT: technical result is disclosed aqueous compositions enable to obtain a stable emulsion and enable to achieve efficient gluing of paper products.
