Problems solved by technology

All these hydrophilic hydroxyl groups cause poor low-temperature film-forming properties of PVAc and poor water resistance of the film, which limits its application, which will lead to quality problems such as mouth drop, air leakage, and uneven adhesion of the joint.

Abstract

The invention provides an organosilicone modified copolymer emulsion tipping adhesive which is prepared from the following materials in parts by weight: 15 to 22 parts of vinyl acetate, 3 to 10 partsof polyvinyl alcohol, 10 to 25 parts of butyl acrylate, 3 to 12 parts of 2-ethylhexyl acrylate, 2 to 4 parts of acrylic acid, 3 to 12 parts of gamma-methylacryloyl oxypropyl trimethoxy silane, 2 to 5parts of vinyl triethoxysilane, 2 to 6 parts of vinyl trimethoxy silane, 4 to 11 parts of deionized water, 1 to 3 parts of a compound emulsifier and 3 to 10 parts of other additives. According to theorganosilicone modified copolymer emulsion tipping adhesive disclosed by the invention and a preparation method thereof, the viscosity and the storage stability are improved, and the rejection rate oftipped cigarettes is reduced.

Description

technical field [0001] The invention relates to the technical field of adhesives, in particular to an organosilicon-modified copolymer emulsion tipping glue and a preparation method thereof. Background technique [0002] When PVAc is polymerized, polyvinyl alcohol is used as a protective colloid, so that the emulsion system contains a large number of hydroxyl groups; in addition, during the polymerization of vinyl acetate emulsion, PV Ac macromolecular side chains are hydrolyzed to a certain extent to produce a certain number of hydroxyl groups. All these hydrophilic hydroxyl groups cause poor low-temperature film-forming properties of PVAc and poor water resistance of the film, which limits its application, which will lead to quality problems such as mouth drop, air leakage, and uneven paste. . In order to improve the quality of cigarette adhesives for cigarettes at high-speed tipping machines, a high-speed tipping glue with good adhesive properties is needed. Contents o...
