Abstract

The invention discloses a preparation method for an environment-friendly starch cigarette adhesive, and belongs to the technical field of adhesives. The method is implemented by the steps of adding water into a reaction kettle with a stirring device, starting the stirring device for stirring when the temperature rises to 40 to 50 DEG C, adding starch, and uniformly stirring the mixture; slowly adding a pretreating agent, performing stirring at high speed, raising the temperature to 70 to 90 DEG C, and performing reaction for 0.5 to 2 hours; slowly adding a modifier, performing stirring at high speed, preserving heat at 70 to 90 DEG C, and performing reaction for 0.5 to 1.5 hours; slowly adding a thickening agent, preserving heat at 70 to 90 DEG C, and performing reaction for 0.5 to 2.5 hours; adding a preservative, performing uniform stirring, reducing the temperature to be lower than 40 DEG C, and performing filtering and discharging. According to the method, natural starch is used as a main raw material, process conditions are improved, and small amounts of volatile organic monomer-free modifier and thickening agent are selected to react with the base material starch, so that the aims of reducing the viscosity, improving the solid content, increasing the curing speed and the like are fulfilled.

Description

Technical field [0001] The present invention is related to a green environmental protection chemical product. It is specific to the preparation method of a starch cigarette glue, which is the field of adhesive technology. Background technique [0002] Cigarettes are a special chemical product. It not only requires non -toxic and harmlessness after burning, does not affect the taste of cigarette rolls, but also requires the product to be cured.Therefore, in industrial production, the quality of curling glue seriously affects the production, quality and raw material consumption of cigarettes.The basic requirements of cigarettes are non -toxic, odorless, pollution -free, excluding organic solvents, strong initial viscosity, fast dryness, good liquidity, good storage stability, and adapting to the needs of high -speed hood development. [0003] There are two types of cigarettes: polymer emulsion and water -soluble.At present, the polymer lotion used in China is mainly PVAC emulsion a...
