Problems solved by technology

Roll paper is mainly used for continuous processing machinery, such as rotary printing, continuous bag making by bag making machine, continuous packaging of cigarettes by cigarette rolling machine, etc. According to the purpose, it can be divided into: packaging paper, printing paper, industrial paper, Office, cultural paper, household paper and special paper, while printing paper refers to a kind of paper used for printing and copying documents. When the printing paper is damp, the ink is not easy to form during printing, resulting in blurred fonts, which brings great inconvenience to printing.
[0003] The existing Chinese patent document (publication number: CN105648835B) discloses a high-performance moisture-proof paper and its preparation method and application. The preparation method includes the following steps: using alkylketene dimer Dry mass, the dosage is 2%-8%; polyamide polyamine epichlorohydrin is used as a reinforcing agent, and the dosage is 0-5% relative to the absolute dry weight of the pulp, for internal sizing; to prepare polyvinyl alcohol solution, add relative It is mixed with 10-15% of the mass of polyvinyl alcohol styrene acrylate and 30-50% of the mass of polyvinyl alcohol-vinyl acetate-ethylene copolymer emulsion, and then added with adhesive and reinforcing agent to make a rubber compound; Good sizing is applied on the surface of the paper machine through a sizing machine to obtain high-performance moisture-proof paper; although this moisture-proof paper has a good moisture-proof effect, it is not suitable for printer printing

Abstract

The invention discloses a printing paper preparation method with moisture-proof function, which comprises the following steps: step 1, starch is dispersed into water to prepare a printing paper with aconcentration of 30 40% slurry, follow by 0.01 0.04% starch branching enzyme, raising the temperature to 35 45. Degree. C., reaction 15. Degree. C 25 min, and then adde concentrated sulfuric acidto that mixture for reaction 4 6 min, and then adde that polyvinyl alcohol, and stirring the mixture continuously for 12 16min, cool to room temperature, standby. The purpose of the invention is toprovide a method for preparing printing paper with moisture-proof function. Compared with the prior art, the printing paper has good moisture-proof effect, high use value and good application prospect.

Description

technical field [0001] The invention relates to the technical field of printing paper preparation, in particular to a method for preparing printing paper with moisture-proof function. Background technique [0002] Paper is a non-woven material made of plant fibers that can be folded arbitrarily for writing. It is generally divided into flat sheets and rolls. Flat paper is mainly used for sheet-by-sheet use, such as paper for flatbed printing, writing, painting, etc. Roll paper is mainly used for continuous processing machinery, such as rotary printing, continuous bag making by bag making machine, continuous packaging of cigarettes by cigarette rolling machine, etc. According to the purpose, it can be divided into: packaging paper, printing paper, industrial paper, Office, cultural paper, household paper and special paper, while printing paper refers to a kind of paper used for printing and copying documents. When the printing paper is damp, the ink is not easy to form durin...
