Abstract

The invention discloses a preparation method of an environment-friendly modified starch adhesive for a cigarette, belonging to the technical field of an adhesive. The adhesive uses the starch as the main ingredient, is free of an organic solvent, is properly modified by adding a small amount of modifying agent, overcomes the inherent defects of the pure starch adhesive, such as low solid content, poor fluidity and poor storage stability, so that the product performance is improved greatly, and the product can meet production of a high-speed cigarette making machine, and is suitable for various cigarette adhesive joints, such as a cigarette holder and a connector. The auxiliary material used in the method is free from harmful substances such as methyl aldehyde and phthalic acid esters, under the premise of meeting the requirement on cigarette production, the sanitary and safe condition meets the sanitary standard of adhesive in China cigarette industry, and real environment-friendly property is realized.

Description

technical field [0001] The invention belongs to the technical field of adhesives, and in particular relates to a preparation method of environment-friendly starch cigarette glue. Background technique [0002] Adhesive is an indispensable material in the cigarette manufacturing process. Adhesives must be used in every production process in the cigarette production process: such as making filter tips, connecting cigarettes and filters (joint glue), cigarette paper rolls (lapping) mouth glue), cigarette small box packaging and cigarette carton packaging, etc. Therefore, the quality of cigarette rubber greatly affects the quality level of cigarettes. Cigarette glue needs to have good bonding strength and fluidity, and its drying speed also needs to meet the high-speed production standards of cigarette machines, and it needs to have a long storage period and stability, and has good adaptability to cigarette equipment. [0003] In cigarette rubber, the mouthpiece glue directly p...
