Problems solved by technology

The development of the tobacco industry has led to the development of related raw and auxiliary materials. The application of new materials and new processes in cigarettes has put forward higher requirements for cigarette adhesives, such as the substantial increase in the speed of cigarette machines and the wide application of self-permeable tipping paper, etc. , the general water-based adhesive will produce U-turn, wrinkle and air leakage when the machine is running at a slightly higher speed. Large, caused by the deformation of the tipping paper during the drying process of the glue. On the other hand, the water-based glue has poor shear resistance and weak adhesion when the machine is running at high speed, resulting in U-turn leakage; Higher requirements are put forward for adhesion, permeability, drying speed and shear resistance under high-speed operation.

Abstract

The invention belongs to the technical field of cigarette mouth glue, in particular to cigarette mouth glue with good wet viscosity and shear resistance and a preparation method thereof. The cigarettemouth glue is synthesized by using an ethylene-vinyl acetate copolymer emulsion as the main raw material, polyethylene glycol as a dispersion medium, a polyvinyl alcohol aqueous solution as a colloidprotective agent, and a modified polyurethane thickener, a non-silicone antifoaming agent, a 2,2,4-trimethyl-1,3-pentanediol diisobutyrate plasticizer, a buffer solution and the like as adjuvant materials. The cigarette mouth glue belongs to a water-based adhesive. The invention has the following beneficial effects: the cigarette mouth glue is suitable for tipping of tipping paper on a high-speedcigarette making machine, and suitable for roll coating of the cigarette equipment; clean operation of machines is guaranteed; and the preparation method is beneficial to high shear viscosity.

Description

technical field [0001] The invention belongs to the technical field of mouthpiece glue for cigarettes, in particular to a mouthpiece glue for cigarettes with good wet viscosity and shear resistance and a preparation method thereof. Background technique [0002] Tipping paper is a kind of cigarette material, which is used for the outer packaging of cigarette filters, and the tipping glue plays the role of bonding filter tips, cigarettes and tipping paper. The development of the tobacco industry has led to the development of related raw and auxiliary materials. The application of new materials and new processes in cigarettes has put forward higher requirements for cigarette adhesives, such as the substantial increase in the speed of cigarette machines and the wide application of self-permeable tipping paper, etc. , the general water-based adhesive will produce U-turn, wrinkle and air leakage when the machine is running at a slightly higher speed. Large, caused by the deformat...
