Embodiment Construction

[0023] The present invention will be further described below in conjunction with embodiment.

[0024] Add 35.5g of water and 6g of polyvinyl alcohol into the dissolution tank, raise the temperature to 88°C under constant stirring, and keep this temperature until the polyvinyl alcohol is completely dissolved. Add 15g of vinyl acetate in the reactor and stir well. Raise the temperature of the reactor to 80°C, stir for 1.5 hours, then add 0.5g of co-polymerization catalyst Zh-4, 30g of vinyl acetate and the prepared polyvinyl alcohol solution, keep the reaction temperature at 80°C, after the reaction, raise the temperature to 90°C , continue to react for 20 minutes. Keep stirring and cool to 60°C, add 10g of cross-linking agent Me-10, and stir thoroughly for 30 minutes. When the temperature drops to 50°C, add 3g of dibutyl phthalate, stir well, cool to room temperature, filter and pack.

Abstract

The invention provides special glue for cigarettes. The special glue for cigarettes comprises vinyl acetate, polyvinyl alcohol, dibutyl phthalate, a crosslinking agent Me-10, a copolymerization catalyst Zh-4 and water. The special glue for cigarettes provided by the invention has the characteristics of water tolerance, heat resistance, freezing resistance, high initial adhesive strength and the like. The special glue for cigarettes is applicable to the conventional different models of cigarette machines in China to serve as cigarette glue and can also serve as high-performance general milk-white glue.

Description

technical field [0001] The invention relates to the field of chemical industry, in particular to a special glue for cigarettes. Background technique [0002] Polyvinyl acetate emulsion, commonly known as latex glue, has a series of advantages such as low price, easy production, convenient use, excellent performance, non-toxic safety, and no environmental pollution. It is widely used in the bonding of porous materials such as paper, fiberboard, and wood. At present, the latex glue used by most cigarette factories in my country is polyvinyl acetate emulsion, and the protective colloid is polyvinyl alcohol. This type of colloid is not resistant to freezing, and it is easy to demulsify the jelly in winter. If it is used in a high-speed cigarette making machine, the cigarette will be damaged such as warped edges and corners. Contents of the invention [0003] The invention overcomes the deficiencies in the prior art and provides a special glue for cigarettes, which is suitable...
