Problems solved by technology

Among them, gelatin and starch adhesives are basically not used due to their low bonding strength and short storage period; the biggest disadvantage of polyvinyl alcohol adhesives is their poor water resistance, and the compressive strength of paper tubes decreases significantly with the increase of storage time. It can be partially improved, but it still cannot meet the requirements; the water resistance of polyvinyl acetate emulsion is better than that of the previous adhesives, but its main disadvantages are low initial adhesion, poor compressive strength and creep resistance of the bonded paper tube

Abstract

The invention discloses a paper tuber adhesive, and a production method thereof. The paper tuber adhesive is prepared from following raw materials, by weight, 32 to 38 parts of vinyl acetate, 8 to 10 parts of siraitia grosvenorii fruit, 7 to 9 parts of polyvinyl alcohol, 2 to 3 parts of ethanediol, 0.5 to 1.5 parts of polyacrylamide, 0.5 to 1.5 parts of dibutyl phthalate, 0.5 to 1.5 parts of an emulsifier, 0.5 part of potassium persulphate, and 110 to 130 parts of purified water. The paper tuber adhesive is high in initial viscous force, short in intial adhesive time, high in bonding strength, and excellent in fluidity and storage stability; and no warping is caused in bonding.

Description

Technical field [0001] The invention belongs to the technical field of adhesives, and specifically relates to a paper tube glue and a production method thereof. Background technique [0002] Adhesive for paper tube (paper tuber) is commonly known as paper tube glue, paper tube glue, etc. It is a special adhesive for making various paper tubes, paper barrels, paper cans and related paper products. Paper, cloth, plastic film, metal foil and other thin and soft materials are usually wound into bundles of paper tubes (paper tubes) to make finished paper core rolls. These paper tubes are generally made of kraft paper or other raw material paper by mechanically rolling and bonding. The adhesive used is called paper tube glue. [0003] With the rapid development of my country's economy, the demand for paper tubes in the fields of daily necessities, textiles, light industry, packaging, leather, etc. is increasing. Such as toilet paper core paper tube, textile yarn tube, cloth, paper prod...
