Cigarette holder adhesive and preparation method thereof

Abstract

The invention discloses a cigarette holder adhesive and a preparation method thereof. The cigarette holder adhesive consists of an aqueous solution of Pullulan and levan, wherein the mass concentration of the Pullulan is 0.1-10 percent (W / V), and the mass concentration of the levan is 0.01-1 percent (W / V). The product does not contain any chemical additive, is combusted into carbon dioxide and water vapor, has slight burnt flavor, is safe to human body, non-toxic and harmless, high in initial adhesion and high in drying speed, does not have monomer residues and can be suitable for performing holder adhesion for a high-speed cigarette making machine at the speed of 10000-12000 cigarettes per minute.

Description

technical field [0001] The invention relates to the technical field of tobacco adhesive preparation, in particular to a cigarette lapping adhesive and a preparation method thereof, which is suitable for the bonding of the longitudinal lapping of cigarettes manufactured in high-speed machine operation and the transverse bonding between cigarettes and filters. Lap joints. Background technique [0002] Most cigarettes are manufactured on high-speed machines that produce 10,000 to 12,000 cigarettes per minute. The speed of these fast machines requires binder formulations with high solids content and low viscosity so that they can be applied quickly to the paper and dried quickly thereon. Cigarettes are usually made by rolling and cutting dry tobacco in paper to form a cylindrical product with a lap the full length of the cigarette. Adhesive is used to secure the longitudinal lap. If the cigarette includes a filter, an adhesive is also used to form the filter and to secure the...

Problems solved by technology

Because EVA comes from petroleum, a non-renewable resource, with the continuous increase in the price of global petroleum products, the production cost of cigarette adhesives is gradually increasing

At the same time, EVA inevitably contains residual monomers of vinyl acetate, which is increasingly unable to meet the environmental protection requirements of cigarette adhesives

Looking back in the 1970s, the adhesives used for cigarettes in my country were mainly starch and dextrin. The raw materials for producing such adhesives belonged to renewable resources, which were not only green and environmentally friendly, but also cost very low. Poor stability, poor bonding performance, fluidity and drying speed, so it was quickly eliminated
