FIELD: chemistry.SUBSTANCE: invention relates to emulsion for paper gluing, which includes gluing agent based on maleated vegetable oil, representing maleated triglyceride, in which at least 50 wt % of the total content of fatty acids in triglycerides are monounsaturated. Invention also relates to paper-gluing agent, including maleated vegetable oil, in which at least 50 wt % of the total content of fatty acids in triglycerides are monounsaturated, and alkenyl succinic anhydride, and/or fatty acid anhydride, and/or anhydride of fatty acid and acetic acid, and/or anhydride of fatty acid and rosin acid. It also relates to method of obtaining paper-gluing emulsion, including emulsification of gluing agent based on maleated vegetable oil, which represents maleated triglyceride, in which at least 50 wt % of the total content of fatty acids in triglycerides are monounsaturated, in water phase by means of emulsifier and/or by means of intensive mixing; or mixing maleated vegetable oil, which represents maleated triglyceride, in which at least 50 wt % of the total content of fatty acids in triglycerides are monounsaturated, with alkenylsuccinic anhydride and/or fatty acid anhydride.EFFECT: invention makes it possible to increase gluing efficiency.26 cl, 17 ex, 7 tbl, 6 dwg |
