GLUE FOR CIGARETTE INDUSTRY AND METHOD FOR ITS PRODUCTION Russian patent published in 1997 - IPC

FIELD: production of cigarettes. SUBSTANCE: proposed glue comprises, mas. %: polyvinyl acetate dispersion, 65.64-65.84; polyvinyl alcohol, 3.06-4.00; aqueous-alcohol solution of sodium methyl siliconate, 0.018-0.027; boric acid, 0.08-0.10; ethanol or isopropanol, 0.10-2.00;5. dibutyl phthalate, 5.60-5.68; and water. Method for production glue involves preparing of aqueous mixture of sodium methyl siliconate and boric acid, adding to it polyvinyl alcohol and mixing at 70-80 C. The process is followed by adding of dibutyl phthalate being heated to 85-95 C, cooling and emulsifying thus prepared mixture. Then polyvinyl acetate dispersion and solution of boric acid in aqueous-alcohol mixture are added. Then thus obtained glue is filtered. EFFECT: improved quality of desired product, improved efficiency of the method. 3 cl
