Problems solved by technology

Because the emulsion stabilization system has not been adjusted in ordinary repolymerization methods, it is difficult to reduce the viscosity to below 300mPa.s while maintaining a relatively high solid content of the emulsion. At the same time, the bonding efficiency of the product is not high, and it is not suitable for high-speed applications.
At present, more and more cigarette factories in my country are beginning to use high-speed cigarette machines with a machine speed of 14,000-16,000 pieces / min. The matching glue requires a viscosity below 200mPa.s, and the bonding speed meets the production needs of 14,000-16,000 pieces / min. , so the viscosity and bonding speed of lap glue produced by ordinary repolymerization methods cannot meet the corresponding requirements

Abstract

The invention provides a low-viscosity high-speed cigarette gum, which is prepared from seed emulsion, vinyl acetate monomer, oxidant, initiator, capture agent, alcohol compound, pH regulator and water; the seed emulsion is vinyl acetate-ethylene One or more combinations of emulsion, vinyl acetate-acrylate emulsion, and vinyl acetate homopolymer emulsion; the solid content of the seed emulsion is 40.0%-65.0%, and the viscosity is 500-5000mPa.s. The invention obtains by first destroying the protective colloid of the emulsion, lowering the viscosity, then polymerizing to rebuild the emulsion stability system, and controlling the number of new latex particles generated. The viscosity of the emulsion prepared by the present invention can be lower than 200mPa.s, which can not only meet the needs of bonding of cigarettes with a machine speed of 14000-16000 pieces / min, but also be used for bonding of common materials, such as paper processing, paint decoration, non-woven fabrics, etc. Manufacturing industries such as textiles and carpets. The preparation method of the invention is simple and suitable for industrial production.

Description

Technical field [0001] The present invention relates to a high-speed cigarette adhesive, particularly relates to a low viscosity and high speed cigarette adhesive preparation. Background technique [0002] In the cigarette production process, the cigarette paper will need tightly packed tobacco, cigarette paper and two side edges abutting the need to eventually form a cylindrical shape, called a cigarette butt glue adhesive glue. The use according to cigarette filters into plastic molding process with plastic (including filter rod, the tow filter rod gum), cigarette making process with plastic (including plastic mouthpiece, take the gum) and the plastic packaging. Press machine speed applicable cigarette unit is divided into different low gum, gum speed (8000 / min) and high speed gum (> 8000 / min). Take the gum is wrapped in cigarette production process of tobacco sheet by adhesive glue, is now normal ride as gum solids content of 50 ± 2%, a viscosity of 500mPa.s-1000mPa.s, ...
