Environmentally friendly high speed cigarette adhesive for filter tipping and preparation method thereof

Abstract

The invention discloses an environmentally friendly high speed cigarette adhesive for filter tipping and preparation method thereof, the cigarette adhesive is prepared from the raw materials of ethylene-vinyl acetate copolymer emulsion, vinyl acetate, alkyl alcohol ether succinic acid monoester disodium, dodecyl sodium sulfate, water, polyvinyl alcohol, hydrogen peroxide, erythorbic acid, antifoaming agent A10, and sodium benzoate. Volatile matters of limited amount of benzene series and formaldehyde and the like in cigarette adhesive cannot be detected from the above raw materials, and the raw materials are of industrial grade. The preparation method comprises the steps of preparing clarified poly vinyl acetate microemulsion and polyvinyl alcohol water solution, adding the polyvinyl alcohol water solution, the poly vinyl acetate microemulsion, the ethylene-vinyl acetate copolymer emulsion and other assistants into a polymerizing pot, stirring, and controlling the viscosity to be 4000-5000 mpa.s, the solid content to be 49-51% and the pH value to be 4.5-5.5, and obtaining the high speed cigarette adhesive for filter tipping, the method is suitable for a cigarette making machine with a machine speed of 14000-16000 pieces / minute.

Description

technical field [0001] The invention provides an environment-friendly high-speed cigarette joint glue and a preparation method thereof, belonging to the cigarette joint glue technology. Background technique [0002] Cigarette water-based glue includes mouthpiece glue, lap glue, packaging glue and mouth rod forming center line glue. The mouthpiece glue is a kind of cigarette glue used for cigarette sticks and filters in the cigarette production process. The glue is applied in the following ways: Two types: one is to apply glue by rolling, that is, the rotation of the first roller transfers the glue in the glue tank to the second roller, and then completes the gluing through the contact between the second roller and the tipping paper. One way of gluing, the nozzle glue needs to form a stable glue line between the two rollers to ensure that the second roller can continue to bring glue; another way of gluing is spraying glue. [0003] At present, tipping paper has developed fro...

AI Technical Summary

Problems solved by technology

At present, there are two types of emulsions used for high-speed cigarette mouthpiece glue: ethylene-vinyl acetate copolymer emulsion and vinyl acetate-acrylate copolymer emulsion. Since their rheological properties and initial viscosity properties cannot meet the production requirements of high-speed cigarette machines, they need to be modified.
