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 paper tube glue and a preparation method therefor. The paper tube glue is prepared from the following raw materials in parts by weight: 15-35 parts of alpha-ethyl cyanoacrylate, 3-7 parts of coumarone-indene resin, 2-8 parts of dibutyl phthalate, 1-5 parts of calcium carbonate, 3-6 parts of talcum powder, 10-15 parts of 2,6-di-tert-butyl-p-cresol, 4-8 parts of N-phenyl-beta-naphthylamine and 20-35 parts of water. The paper tube glue prepared by the preparation method has the characteristics of good initial adhesion, short initial adhesion time, high bonding strength, fluidity, no warping in bonding and good storage stability; by applying the paper tube glue to the manufacturing of paper tubes, manufactured paper tube products have the advantages of high strength, high stiffness and no embrittlement. The paper tube glue disclosed by the invention can be applied to the mechanical production of all kinds of high, medium and low paper tubes, can also be applied to the production of paper barrels, is used for replacing adhesives for the paper tubes such as white latex, polyvinyl alcohol and the like and is wide in range of application.

Description

technical field [0001] The invention relates to the field of packaging materials, in particular to a paper tube glue and a preparation method thereof. Background technique [0002] Paper tubes have good development and application prospects, and can be used as substitutes for metal, glass, and ceramic packaging containers.
