Abstract
The invention provides a method for preparing gravure paper, which comprises the following steps of: collecting and cleaning leather scraps, and soaking the leather scraps in sodium hydroxide solution for 1.5 hours; dispersing a mixture formed by the leather scraps and sodium hydroxide to fully disperse the leather scraps in the sodium hydroxide solution so as to obtain protein fiber dispersoid slurry; adding the protein fiber dispersoid slurry into bleached wheat straw pulp and uniformly mixing to obtain paper pulp; adding aluminum sulfate solution into the paper pulp, uniformly mixing, and standing for 5 to 6 minutes; and finally making the gravure paper. The gravure paper prepared by the method does not have holes generated by cellulose combination, so that the bonding force between fibers is improved; therefore, the printing ink is not easy to fall off after printing, and the smoothness of the paper is improved.
Description
[technical field]
The present invention relates to a kind of preparation method of printing paper, particularly a kind of preparation method of gravure paper.
[background technology]
The gravure paper paper is pure white strong, has good smoothness and resistance to water, therefore, be mainly used in quality requirements such as printing senior magazine, senior wall calendar, fine arts picture high and printed matter.
Traditional gravure paper after being completed for printing, appearance China ink pull-up that can be the in various degree phenomenon that falls, just ink pigment comes off because of slight friction, trace it to its cause, mainly be that the moisture of paper is lower, therefore because the gap between paper fibre is bigger, printing ink absorbs too fast at paper surface, the chromatophore of printing ink is penetrated in the paper excessively, thereby, can not be formed for the fixedly epithelium of pigment, so, cause printing ink to come off; In addition, traditional gravure paper is not high owing to smoothness, and when printing tiny site, tiny site is fallen the pocket of paper sometimes, so, do not print, definition decline, the gradation of colour picture are reduced, printing effect is relatively poor.
[summary of the invention]
Technical problem to be solved by this invention provides a kind of preparation method of gravure paper, by the gravure paper that this method prepares, and difficult drop-off behind the ink printing, and smoothness is obviously higher.
For achieving the above object, the invention provides a kind of preparation method of gravure paper, may further comprise the steps:
Step 1: collect the leather bits, foreign material in the leather bits are cleaned out, after with running water the impurity on leather bits surface being rinsed well again, it is joined mass concentration is in 5% sodium hydroxide solution, under 55 ℃ of conditions, soaked 1.5 hours, wherein, the mass ratio of sodium hydroxide solution and leather bits is 30: 1;
Step 2: the mixture that leather is considered to be worth doing and NaOH forms that step 1 obtains is evacuated processing, open so that the leather bits are fully evacuated in sodium hydroxide solution, thereby, obtain azelon dispersion slurries;
Step 3: get bleached wheat straw pulp, make paper pulp to wherein adding the azelon dispersion slurries that step 2 obtains and mixing, wherein, to account for the mass percent of azelon dispersion slurries and bleached wheat straw pulp mixture be 2～6% to azelon dispersion slurries;
Step 4: the adding mass concentration is 2% aluminum sulfate solution in the paper pulp that step 3 obtains, and mixes the back and places 5-6 minute, copies then and gets gravure paper, and the mass ratio of described paper pulp and aluminum sulfate solution is 20: 1.
The preparation method of gravure paper of the present invention has the following advantages at least: have gloss, the feel as the cashmere, whole body water white transparency as the silk because of azelon 1., similar to string, all be natural linear macromolecule, miscibilty is strong, can be used for the exploitation of high-grade paper; 2. after azelon applying glue liquid of the present invention and bleached wheat straw pulp mix, the gravure paper of manufacturing paper with pulp can remedy string in conjunction with the hole that produces, the filler particles and the fiber fines that are about to paper better adhere on paper, strengthened the adhesion between the fiber, improve the liquid-repellency energy of paper greatly, avoid too fast and undue being penetrated in the paper of chromatophore printing ink of the absorption of inks of paper surface to go; 3. because can remedy string, the reducing property of the tiny site of printed matter is improved so can improve smoothness of paper in conjunction with the hole that produces.
