example 1

[0025] Weigh the potatoes, peel them and cut them into cube potato pieces with a side length of 1 cm. Put the obtained potato pieces into a stone mortar and mash them with a stone pestle for 20 minutes to obtain mashed potatoes. The ratio of the mashed potatoes to water is After mixing 1:5, rub and wash with hands repeatedly for 15 minutes; after washing, filter with three layers of gauze to separate and remove the filter residue to obtain a milky white filtrate. After mixing the filtrate and polyacrylamide at a mass ratio of 100:1, leave it still Let it settle for 10 hours, remove the supernatant to obtain the bottom viscous starch slurry; mix the starch slurry and the 5% polyvinyl alcohol solution at a mass ratio of 10:1 and put them into a three-necked flask with a thermometer and a stirrer After heating to 70°C, add 10% glyoxal with polyvinyl alcohol solution mass and 1% potassium persulfate with polyvinyl alcohol solution mass to the three-necked flask, keep the temperature...

[0029] Weigh the potatoes, peel them and cut them into cube potato pieces with a side length of 1 cm. Put the obtained potato pieces into a stone mortar and mash them with a stone pestle for 30 minutes to obtain mashed potatoes. The mass ratio of the mashed potatoes and water is After mixing 1:5, rub and wash with hands repeatedly for 20 minutes; after washing, filter with three layers of gauze to separate and remove the filter residue to obtain a milky white filtrate. After mixing the filtrate and polyacrylamide at a mass ratio of 100:1, leave it still Settling for 12h, remove the supernatant to obtain the bottom viscous starch slurry; mix the starch slurry and the 5% polyvinyl alcohol solution at a mass ratio of 10:1 and put them into a three-necked flask with a thermometer and a stirrer After heating to 80℃, add 10% glyoxal with polyvinyl alcohol solution mass and 1% potassium persulfate with polyvinyl alcohol solution mass to the three-necked flask, keep the temperature and ...

Abstract

The invention relates to the technical field of preparation of adhesive, in particular to a preparation method of high-viscosity starch-based paper tube adhesive. According to the preparation method, potato starch is extracted from potatoes, the potato starch, polyvinyl alcohol and oxalaldehyde are subjected to crosslinked polymerization, and the viscosity of the starch-based adhesive is improved, so that the adhesion viscosity of the traditional starch adhesive is improved; fermenting liquid enriched amino acid and organic carboxylic acid and imvite for expanding the interlayer spacing are mixed, the amino acid and the organic carboxylic acid in the fermenting liquid are further degraded under the action of microorganisms, the generated amino groups and carboxylic groups are grafted and attached to the interlayer and the surface of the imvite, the number of the hydrophilic amino groups and the carboxylic groups on the interlayer and the surface of the imvite is increased, and the hydrophilic imvite is obtained; and the obtained hydrophilic imvite and the starch-based adhesive are mixed to obtain the piper tube adhesive, wherein the hydrophilic imvite has extremely high hydrophilic water-absorbility, free water at the periphery of the base adhesive is reduced and the base adhesive particles are sticky to form films easily, so that the initial adhesion time of the paper tube adhesive is reduced.

Description

Technical field [0001] The invention relates to the technical field of adhesive preparation, in particular to a method for preparing a high-viscosity environment-friendly paper tube glue. Background technique [0002] There are many components in the composition of adhesives that are harmful to the environment and human health. It is urgent to change the composition of raw materials and improve the level of corporate management. There are many classification methods for adhesives, and there are different classifications from different angles. Starting from the concept of environmentally friendly adhesives, there are not many types and varieties of truly environmentally friendly adhesives at home and abroad. From the current and development point of view, the environmentally friendly adhesive is the only adhesive in the future. It is the need for environmental protection and the need for human survival. The development of the adhesive industry and the industrial production of adhe...
