Problems solved by technology

This technology discloses a nitrogen-containing synthetic resin additive, which is added to a composition with a binder ratio of 6-20 and a pigment content of 100 to obtain a coating solution. The binder is selected from a wide range of styrene-butadiene latex , acrylic latex or even natural binder, the choice of binder is basically not limited, the preparation process of the coating solution is relatively complicated, and the performance of the coating for water-based ink is unknown
[0008] At present, most of the inkjet paper coating formulas listed above come from developed countries such as Japan. Obviously, the research and development of various raw materials and technologies are based on their own markets and technologies, and are not suitable for the production and processes of domestic manufacturers in China.

Embodiment Construction

[0032] A variety of component formulations as listed in Table 1 have been adopted, all adding 800 parts by weight of water, and the coating slurry prepared by proportioning is 180g / m2 on the roller coating equipment. 2 Double-adhesive paper with 100g / m 2 The slurry coating amount is coated, and the high-gloss inkjet paper embodiment of the present invention is obtained, and the water resistance, gloss and whiteness data of these high-gloss inkjet paper products are also listed in the table. Because the parameters of gloss, whiteness, and water resistance can directly reflect the fineness of pores, the size and quantity of pores, and other properties of the coating and film layer. Among them, SBD-1 digital whiteness meter is used for gloss test; GB / T9754-1988 standard method is used for whiteness measurement.

Abstract

The invention relates the high gloss paper. On the front and back of the base paper there are solid front coating and back coating. The front coating comprises bottom coating and face coating. In face coating there is the second class particle composed by silica dioxide and calcium carbonate. On the surface of the second class particle there is dispersing agent film and the particle diameter of the second class particle is 300nm-500nm. The binding agent of face coating comprises PVA and EVA. The dispersing agent of face coating is sodium polyacrylate, polystyrene-cis-1.2-ethylenedicarboxylic acid, polytrimethylene allyl group amchlor. The method is easy to get raw material, simple formulation, good fixation property, mildew-resistant and water resistant and low cost.

Description

【Technical field】 [0001] The present invention relates to printing paper, and more particularly, the present invention relates to a high-gloss coated paper for ink-jet printers. 【Background technique】 [0002] Traditional high-grade color printing uses high-gloss printing paper (commonly known as coated paper) coated with an ink-absorbing coating. These coated papers include base paper and coatings on the surface of the base paper. The base paper itself is added or Some additives are not added, and the coating is composed of pigments, dispersants, fluorescent agents, film-forming agents, adhesives, lubricants and other additives to form a composite coating liquid, and the composite coating liquid is coated On the surface of fiber-based base paper, traditional high-gloss printing paper can be obtained after drying and smoothing treatment. According to the coating amount of the coating liquid on the surface of the base paper, it is divided into coated paper, ordinary coated p...
