Abstract

The invention belongs to the technical field of novel cigarette materials, in particular relates to a high speed cigarette mouth building hot melt adhesive and a preparation method thereof. The cigarette mouth building hot melt adhesive is prepared from ethylene-vinyl acetate copolymer, tackifying resin, nanometer silicon dioxide and antioxidant, and includes the following components according to percentage by weight: 25 to 35 percentages of ethylene-vinyl acetate copolymer, 35 to 45 percentages of tackifying resin, 20 to 40 percentages of viscosity modifier, 5 to 10 percentages of nanometer silicon dioxide and 0.1 to 0.5 percentage of antioxidant, wherein the components are heated and melted by a reaction kettle and are sequentially added and uniformly stirred. The cigarette adhesive prepared by the method has strong quick-drying performance, the ring and ball softening point nearly ranges from 95 to 105 DEG C, the softening range is from 5 to 8 DEG C, the operation of adhesion can be accomplished in 5 seconds, and the cigarette adhesive has the characteristics of no solvent, no absorption of moisture, corrosion resistance, aging resistance, and the like; the flowability and the wetting quality of the adhesive can be controlled by changing the parameters of wax, the method is suitable for the preparation of different cigarettes, and the adhesive and the method have good value of market popularization and application.

Description

technical field [0001] The invention belongs to the technical field of new cigarette materials, and in particular relates to a high-speed cigarette lapping hot melt adhesive and a preparation method thereof. Background technique [0002] Cigarette lap glue is used for the bonding of cigarette paper in cigarette production. The bonding effect is completed in the high-speed cigarette process. The adhesive should be soaked into the cigarette paper, and the paper and paper can be firmly bonded after curing. In actual production, due to differences in production environments and raw materials, the specific requirements for lapping glue are not the same. However, the lap glue must at least meet the following quality requirements: it should be colorless, non-toxic, odor-free, and non-irritating; it should have strong initial adhesion, fast bonding speed, appropriate viscosity, relatively Good fluidity and wettability; the bonded joint must be firm, with certain moisture-proof, moi...
