Embodiment 1～3

[0107] Table 1 shows the formulations of topcoat coatings, formulations of coatings used for coated paper coatings, and types of coated paper base paper used in Examples 1 to 3.

[0108] Among them, the ash in the coated paper base paper is a mixture of ground calcium carbonate and precipitated calcium carbonate.

[0109] The preparation methods of the coating used for the top coating and the coated paper coating are conventional in the field, and each component is mixed uniformly.

[0110] Precipitated calcium carbonate is used as the pigment of the ink-jet receiving surface coating, and an appropriate anionic dispersant is added to adjust the PCD value of the pigment particles to be between -100 and 0 μeq / L. The embodiment uses a physical method to adjust the size of the pigment particles to a D50 of 0.4-0.8 μm. In terms of mass percentage, more than 60% of the pigment particles are larger than 0.2 μm, and the mass accumulation percentage of the pigments with a particle size...

Embodiment 4

[0119] Except that there are differences in the following operations or parameters, others are the same as in Example 1.

[0120] Preparation of ink-jet printing paper: on both sides of base paper, coating top coating (the coating amount of each side is 24g / m 2 ), after drying and calendering, top coats are formed on both sides of the base paper respectively to obtain inkjet printing paper. In the coating process of the top coat layer, the number of times of coating is not limited, and may be one coating or multiple coatings.

[0121] The structure of inkjet printing paper includes: the first surface coating, base paper, and the second surface coating. Such as figure 1 As shown in B, among them, 6 is the first surface coating, 7 is the base paper, and 8 is the second surface coating.

[0122] Among them, in the base paper, the grammage is 55g / m 2 , the ash content is 14%, and the Cobb value is 21g / m 2 , table glue.

Embodiment 5

[0124] Except that there are differences in the following operations or parameters, others are the same as in Example 1.

[0125] A paper for inkjet printing, its structure includes a base paper, one side of the base paper contains one side coating, such as figure 1 Shown in C, wherein, 9 is the surface coating, and 10 is the base paper. The coating amount of the top coat is 24g / m 2 . Among them, in the base paper, the grammage is 55g / m 2 , the ash content is 14%, and the Cobb value is 21g / m 2 , table glue.

Abstract

The invention discloses ink jet printing paper and a painting thereof. The painting comprises the following components of a cationic-system pigment, an adhesive and an anionic polymer, wherein the adhesive is silane-modified polyvinyl alcohol. The painting of the ink jet printing paper has the advantages that the cost of the raw material is lower, the solid content can reach 50%, the water retention property is good, and the painting is suitable for large-scale production; the painting can be normally produced on large and high-speed blade coaters, and the coating speed can reach 1100 m / min orabove. The ink jet printing paper with the painting layer can meet the requirements of quick printing speed, clear imaging, high color concentration, and bright color, and also meet the high-qualityprinting requirements of high-speed commercial ink jet printers.

Description

technical field [0001] The invention relates to an ink-jet printing paper and the coating used therefor. Background technique [0002] In the environment of rapid network development, digital inkjet printing has replaced the traditional printing process and has become the leading printing industry in the printing industry with its advantages of printing from one sheet, no need for plate making, instant printing, instant error correction, variable printing, and on-demand printing. development trend. With the wide application of digital inkjet printing, the demand and quality requirements for inkjet printing paper are gradually increasing. [0003] The composition of inkjet printing paper can be divided into two layers: paper base and surface coating. The main composition of the paper base is usually composed of bleached kraft pulp and mineral fillers such as calcium carbonate. The function of the surface coating is to improve the uniformity of the paper surface and improve...
