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 preparation method thereof. The paper tube adhesive is prepared by, by weight, 32-38 parts of vinyl acetate, 8-10 parts of 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 prepared by the method is high in initial adhesion, short in initial adhesive time, high in binding strength, high in fluidity and storage stability and free of warping during binding.

Description

technical field [0001] The invention belongs to the technical field of adhesives, in particular to paper tube adhesives and a preparation method thereof. Background technique [0002] Paper tube glue, also known as paper tube glue, paper corner glue, paper corner glue, white glue, etc., is used to make rolls of toilet paper core paper tubes, textile yarn tubes, cloth, paper products, leather, plastic films, etc. Paper tubes, paper corner protectors, paper tubes, paper drums, etc. for tube packaging. Traditional paper tube glue generally uses white latex, dextrin or other emulsion products, which have disadvantages such as high production cost, complicated production engineering, slow drying, low initial viscosity, and low cost performance. [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, text...
