example 1

[0025] In parts by weight, add 20 parts of nano-silica, 40 parts of silane coupling agent and 100 parts of ethanol solution into a beaker, stir and mix for 50 minutes at a speed of 500 r / min to obtain a mixed solution, and then mix the obtained liquid filtration to obtain a filter cake, and wash the filter cake with absolute ethanol for 5 times to obtain a wet material, and then place the wet material in a vacuum freeze-drying oven to dry for 40 minutes to obtain a modified nano-silica, and then the obtained modified nano-silica Silicon oxide and absolute ethanol were transferred to an ultrasonic disperser at a mass ratio of 1:100, and ultrasonically dispersed for 30 minutes at an ultrasonic frequency of 85 kHz to obtain a modified nano-silica dispersion; glass fiber and modified nano-silica Mix and impregnate the silicon dispersion solution at a mass ratio of 1:20 for 5 hours to obtain impregnated glass fibers. Transfer the impregnated glass fibers and dopamine solution into a...

example 3

[0029] In parts by weight, take 60 parts of polyvinyl alcohol, 20 parts of polyvinyl acetate emulsion, 10 parts of cyclodextrin derivatives, 0.02 parts of cellulase, 6 parts of glass fiber, 200 parts of water, 6 parts of polystyrene For the emulsion, first add polyvinyl alcohol, cyclodextrin derivatives and water into the mixer, stir and mix at a high speed of 1300r / min for 50min, then add polyvinyl acetate emulsion, cellulase, The glass fiber and polystyrene emulsion were continuously stirred and mixed at a high speed of 1300r / min for 50min to obtain the special paper tube glue for paper surface. The solid content of the polyvinyl acetate emulsion is 30%. The cyclodextrin derivative is α-cyclodextrin. The model of the silane coupling agent is silane coupling agent KH-550. The ethanol solution mass fraction is 50%. The glass fiber is an ultrafine glass fiber; the ultrafine glass fiber has a length of 14 μm and a diameter of 4 μm. The solid content of the polystyrene emulsi...

Abstract

The invention discloses a special paper tube adhesive for paper and belongs to the technical field of binding agents. The special paper tube adhesive for the paper is prepared by the following steps:stirring and mixing nano silicon dioxide, a silane coupling agent and an ethanol solution and reacting; then filtering, washing and drying to obtain modified nano silicon dioxide; then carrying out ultrasonic dispersion on the modified nano silicon dioxide and absolute ethyl alcohol to obtain a modified nano silicon dioxide dispersed solution; mixing glass fibers and the modified nano silicon dioxide dispersed solution and immersing; then drying the immersed glass fibers until the weight is constant; mixing the immersed glass fibers and a dopamine solution and immersing; then drying the immersed glass fibers until the weight is constant, so as to obtain modified glass fibers; stirring and mixing polyvinyl alcohol, a cyclodextrin derivative and water; then adding polyvinyl acetate emulsion,cellulase, the glass fibers and polystyrene emulsion, and stirring and mixing to obtain the special paper tube adhesive for the paper. The special paper tube adhesive for the paper, which is preparedby the technical scheme, has the characteristics of excellent bonding performance and has a wider application and development field.

Description

technical field [0001] The invention discloses a special paper tube glue for paper surface, which belongs to the technical field of adhesives. Background technique [0002] With the improvement of living standards, the paper product industry is advancing by leaps and bounds, and the consumption of paper tube glue is also increasing day by day. For example, paper tubes for pressure-sensitive tapes, yarn tubes for textiles, composite packaging cans for food and beverages, roll tubes for plastic films, and paper tubes for mechanized production of roll tubes for silk, cloth, paper products, leather, etc., require a large amount of paper tubes and reels. And as the auxiliary material of the above-mentioned products, its paper tube and reel must have a kind of performance excellent, the paper tube glue with high bonding strength to guarantee its quality. Adhesive for paper tubes is commonly known as paper tube glue, paper tube glue, etc. It is a special adhesive for making vario...
