Problems solved by technology

[0004] Problems encountered by the original mouthpiece adhesive when bonding cellulose acetate tipping paper for cigarettes: the machine runs at a very low speed or cannot be bonded. When the machine runs at a slightly higher speed, poor rubbing, wrinkles and leakage will occur Secondly, after the glue is completely dry after bonding, the tipping paper is prone to wrinkle phenomenon. Caused by the deformation of the tipping paper

Abstract

The invention discloses a holder adhesive for cellulose acetate cigarette tipping paper. The holder adhesive is prepared from 70-90% of a VAE emulsion and 10-30% of an additive, and the additive comprises polyvinyl alcohol, a plasticizer, a tackifier, an antifoaming agent and a bactericide. The holder adhesive has the characteristics of environmental protection, no boric acid, excellent wet viscosity, excellent in-machine stability, and realization of clean running of a machine.

Description

technical field [0001] The invention relates to the technical field of tipping glue for cigarette tipping paper, in particular to a tipping glue for cellulose acetate cigarette tipping paper. Background technique [0002] Tipping paper is a kind of material for cigarettes, which is used for the outer wrapping of cigarette filters, and the tipping glue plays the role of bonding filter tips, cigarettes and tipping paper. [0003] The development of the domestic 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, among which cellulose acetate cigarette tipping paper is an example. The difference between the tipping paper and the original tipping paper for cigarettes is: the tipping paper is made of cellulose acetate, while the ordinary tipping paper is processed from natural plant fibers; the surface of the tipping paper i...
