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, 65.66-65.73; polyvinyl alcohol, 3.06-3.84; aqueous-alcohol solution of sodium methyl siliconate, 0.02-0.03; sodium tetraborate, 0.065-0.096; glycerine, 0.50-0.96; dibutyl phthalate, 5.60-5.68; and water. Method for production glue involves preparing of aqueous mixture of sodium methyl siliconate and sodium tetraborate, 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 aqueous mixture of sodium tetraborate and glycerine are added. EFFECT: improved quality of desired product, improved efficiency of the method. 3 cl
