Embodiment 1

[0030] (1) Preparation of 10% gelatin aqueous solution

[0031] Take 20g of gelatin and 180g of distilled water and place them in a container, heat them in a hot water bath at 80°C, stir and dissolve completely, and then prepare a 10% gelatin aqueous solution for use;

[0032] (2) Preparation of 20% acrylate-acrylamide copolymer aqueous solution

[0033] Add 12g of potassium acrylate, 8g of acrylamide, and 70g of distilled water into the reaction flask, stir and heat up to 70°C, then dropwise add a solution of 0.05g of potassium persulfate and 10g of distilled water, then continue the reaction at 70°C for 3 hours, and finally raise the temperature to 90°C ℃ for 1 hour, cooled to obtain 20% acrylate-acrylamide copolymer aqueous solution, ready to use;

[0034] (3) Coating preparation for inkjet printing paper

[0035] Add 95g of 10% gelatin aqueous solution prepared by step (1), 4.9g of 20% acrylate-acrylamide copolymer aqueous solution prepared by step (2), and 0.1g of sodiu...

Embodiment 2

[0037] Except replacing potassium acrylate with sodium acrylate, and replacing potassium persulfate with sodium persulfate, the others were the same as in Example 1, thus preparing the coating for inkjet printing paper.

Embodiment 3

[0039] Except that ammonium acrylate was used to replace potassium acrylate, and ammonium persulfate was used to replace potassium persulfate, the others were the same as in Example 1, thereby preparing the coating for inkjet printing paper.

Abstract

The invention relates to a dope for ink-jet paper and the manufacturing method. the basic component of dope is that 93. 8-96. 8% of 10% gelatin aqueous solution, 2. 95-6. 15% of 20% copolymer water solution of acrylic salt and acrylamide, and 0.05-0.25% of water-soluble assistant sodium benzoate. The acrylic salt is the one or the mixture of two kinds or three kinds of sodium acrylate, potassium acrylate, or ammonium acrylate. Manufacturing procedures are that (1) preparing 10% gelatin aqueous solution, (2) preparing 20% copolymer water solution of acrylic salt and acrylamide, (3) preparing the dope for ink-jet paper. The dope in invention is even transparent solution and there is no insoluble matter of solid color packing in it. The rigidity of dope can not be improved so as to maintain the folding performance of paper. The copolymer of acrylic salt and acrylamide prepared by special process is used as absorbing water agent. It is provided with simple manufacturing method, no contamination discharge, low producing cost, poisonless and harmless, easily natural degradation and convenience recovery of printing paper to use.

Description

technical field [0001] The technical solution of the present invention relates to the coating of the coating without pigment of paper, in particular the coating for ink-jet printing paper and its preparation method. Background technique [0002] With the popularization of computers, related auxiliary products have also been developed, and printers are one of them. Inkjet printers can print in color, and their printing principle is to spray ink onto printing paper through micropores according to the printing signal. Due to the influence of paper fiber length and width, pores, etc., the ink spreads and penetrates unevenly on the surface of the paper, which makes the printing effect worse, especially for color printing, and the quality of the picture is very poor. Improving the uniformity of the paper surface can improve the quality of inkjet printing. [0003] Coating a layer of paint on the surface of ordinary printing paper is one of the effective methods to improve the un...
