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 tube adhesive and a production method thereof. The paper tube adhesive is made by, by weight, 32-38 parts of vinyl acetate and 8-10 parts of mango peel, 7-9 parts of poval, 2-3 parts of glycol, 0.5-1.5 parts of polyacrylamide, 0.5-1.5 parts of dibutyl phthalate, 0.5-1.5 parts of emulsifier, 0.5 part of potassium persulfate and 110-130 parts of pure water. The paper tube adhesive produced by the method is high in initial adhesiveness, short in initial adhesive time, high in adhesive strength, high in fluidity and storage stability and free of adhesive warping.

Description

technical field [0001] The invention belongs to the technical field of adhesives, and in particular relates to paper tube adhesives and a production method thereof. Background technique [0002] Adhesive for paper tubes 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 with paper tubes (paper tubes) to make paper core rolls. These paper tubes are generally made of kraft paper or other raw paper mechanically rolled and bonded, and 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 roll inner core paper tube, textile yarn tube, cloth, paper product, leather, ...
