Abstract

The invention discloses a preparation method of a bonding agent for a paper tube. The preparation method comprises the following steps of 1, placing deionized water, polyvinyl alcohol and the like in a reaction kettle, performing stirring and temperature rise, adding sodium dodecyl benzene sulfonate and the like, and performing stirring, 2, adding alkylphenol polyvinylether carboxymethyl sodium and the like, and continuing to perform stirring, 3, adding a konjak powder solution and the like, and continuing to perform stirring, 4, adding compound starch and the like, and performing stirring and temperature rise, and 5, adding an enzymatic hydrolysate and the like, and performing stirring and filtering, wherein a preparation method of the konjak powder solution comprises the concrete steps of uniformly mixing konjak powder, cetyl trimethyl ammonium bromide and the like, adding a chloroauric acid solution, performing stirring until a brilliant yellow color becomes clarified, adding a concentrated HCl solution, performing stirring and standing, adding a chitosan solution, performing mixing, and performing ultrasonic treatment and centrifugation to take a supernate. The prepared bonding agent has the benefits that the bonding agent is short in paper fiber breaking time, high in bonding strength, good in flowability and good in storage stability.

Description

technical field

[0001] The invention relates to the technical field of adhesives. More specifically, the present invention relates to a method for the preparation of adhesives for paper tubes. Background technique

[0002] At present, the amount of packaging paper tubes is increasing day by day, but the production level is limited. The quality of the commonly used polyvinyl formal paper tube glue is uneven. It is difficult to control the temperature, pH and time of the condensation reaction. It is extremely harmful to the human body. Although a certain amount of formaldehyde neutralizer is added, the unavoidable residue still endangers the health of the paper tube glue production personnel and the paper tube factory operators. There will also be a small amount of formaldehyde in the rolled out paper tube Residues constitute a potential hazard to the health of the user. At the same time, the viscosity of the paper tube glue is poor, the time to destroy the paper fiber is lon...
