Abstract
The invention relates to paper tube glue and a preparation method thereof. The paper tube glue comprises the following components in percentage by weight: 20 to 35 percent of polyvinyl alcohol (PVA) solution, 5 to 15 percent of starch paste solution, 20 to 40 percent of porcelain clay dispersion liquid, and 20 to 40 percent of water. The preparation method comprises the following steps: 1) gelatinizing polyvinyl alcohol (PVA) solution dry powder; 2) performing aldolization on the polyvinyl alcohol (PVA) solution; 3) adding gelatinized starch; 4) adding the dispersed porcelain clay dispersion liquid; and 5) adding water for dilution. The paper tube glue containing the components of the polyvinyl alcohol (PVA) solution, the starch paste solution, the porcelain clay dispersion liquid and the like is prepared by the method of adding the gelatinized starch and the dispersed porcelain clay dispersion liquid into the polyvinyl alcohol (PVA) solution after the aldolization. The paper tube glue prepared by the method has strong bonding force, and when the paper web is wide and paper needs to be wound into small volumes and a paper winding machine runs at a high speed, the paper tube glue prepared by the method can bear the weight of the paper on a cylindrical paper tube.
Description
Technical field
The paper tube glue and the paper tube glue making method of the paper tube that uses when the present invention relates to coil paper in the paper industry.
Background technology
In the paper industry, Reel batches the paper web of producing, and paper web needs cut into rouleau according to requirement of client during than broad, just needs by Rewinding rewinding process.In Rewinding rewinding process, 6 inches or 12 inches round shape paper tube that coil paper generally uses craft paper to make, according to the length requirement of coil paper, coil paper on the paper tube offers the client after spooling.
Employed round shape paper tube is a multilayer craft paper and glue is bonding forms during coil paper.The Rewinding rewinding process machine that paper is rolled into rouleau needs high-speed cruising.The words of bonding make a concerted effort weak or the poor stability of paper tube adhesive, in the machine high speed rotating process strength ratio of paper tube a little less than, will bear the weight that incessantly twists in the paper on the round shape paper tube, thereby can cause the paper tube distortion, and paper may damage in printing, keeping and the transporting sheets process, produces defective products.
Summary of the invention
The object of the invention is exactly in order to overcome when paper is rolled into rouleau, winder speed is too fast, weak or the poor stability of the bonding force of paper tube adhesive, paper tube bears the weight that incessantly twists in the paper on the round shape paper tube, and cause paper tube to be out of shape, shortcomings such as paper may damage in printing, keeping and transporting sheets process.
In order to overcome the above problems, by the following technical solutions:
A kind of paper tube glue, by weight percentage, its prescription comprises following composition: PVA polyvinyl alcohol solution 20～35%, starch paste liquid 5～15%, Clay china clay dispersion liquid 20～40%, water 20～40%.
The preparation method of this paper tube glue, its method steps is:
1) PVA polyvinyl alcohol dry powder gelatinization process;
2) PVA polyvinyl alcohol solution aldolization;
3) add pasted starch;
4) add scattered Clay china clay dispersion liquid;
5) thin up.
The preparation process of described pasted starch is for being that 80%～99% PVA polyvinyl alcohol dry powder mixes with water with basicity, making gelatinization concentration is 10%～20% by weight percentage, temperature is after 85 ℃～95 ℃ the transparent paste liquid, maintain the temperature under 85 ℃～95 ℃ the situation, keep 10～40 minutes time.
Described aldolization is for when temperature is 60 ℃～75 ℃, be to add hydrochloric acid in 10%～20% the PVA polyvinyl alcohol solution by weight percentage toward gelatinization concentration, with the acid pH value of PVA polyvinyl alcohol solution furnishing is 2～3, be to add weight in 2～3 the PVA polyvinyl alcohol solution to account for PVA polyvinyl alcohol solution weight be 1%～1.8% formaldehyde stoste toward pH value again, behind the aldolization 1～2 hour, adding the NaOH caustic soda soln again, is 5～6 with PVA polyvinyl alcohol solution furnishing slightly acidic pH value.
The preparation process of described pasted starch is that tapioca (flour) is mixed with water, and making gelatinization concentration is 10%～20% by weight percentage, and temperature is after 85 ℃～95 ℃ the transparent paste liquid, and keeping temperature is 85 ℃～95 ℃ times of keeping 10～40 minutes.
Described china clay dispersion liquid preparation process is, by weight percentage, with accounting for weight is 65%～75% Clay china clay and to account for weight be 29.80%～29.90% water, with accounting for weight is that 0.1%～0.2% china clay dispersion agent disperses Clay china clay, and is china clay dispersion liquid furnishing pH value 6～7 with the NaOH caustic soda soln.
Described hydrochloric acid concentration by weight percentage is 30%～36%.
Described NaOH caustic soda soln concentration by weight percentage is 25%～35%.
The whiteness of described Clay china clay is 80～95%, and particle diameter is to account for 90～100% of china clay sum below 2 microns.
The present invention utilizes toward the method through the starch that adds gelatinization in the PVA polyvinyl alcohol solution behind the aldolization and scattered china clay dispersion liquid, prepares the paper tube glue of main components such as containing PVA polyvinyl alcohol solution, starch paste liquid, Clay china clay dispersion liquid.Need be rolled into rouleau at paper web than broad, and winder runs up down, utilize paper tube of the present invention can bear the weight that twists in the paper on the round shape paper tube, paper tube can not be out of shape.
