Abstract

The present invention provides a matte coated paper with ultra-fine surface feeling and its preparation method. The matte coated paper comprises the following components: a base paper layer, a pre-coat layer and a top coat layer, and the base paper layer slurry comprises the following parts by weight Raw materials: 50-90 parts of short fiber pulp, 5-30 parts of long-fiber pulp, 5-30 parts of mechanical pulp, 2-5 parts of flow aid, 1-4 parts of filter aid, 3-8 parts of cationic starch; The paint includes the following raw materials by weight: 70-90 parts of ground calcium carbonate, 60-80 parts of light calcium carbonate, 50-70 parts of latex, 20-26 parts of starch, 4-6 parts of dispersant, and 3-5 parts of defoamer , 3-9 parts of lubricant, 5-8 parts of thickener, 3-5 parts of lye, the matte coated paper prepared by the invention by improving the smoothness of the base paper and optimizing the formula of the coating has fine and smooth paper surface and high printing performance , small flexibility, high book strength, can be adapted to high-speed printing machines.

Description

technical field [0001] The invention relates to the technical field of papermaking, in particular to a matte coated paper with a super-fine surface feel and a preparation method thereof. Background technique [0002] At present, matt art paper products in domestic and foreign markets are gradually divided into two categories. One is relatively low-end matt paper, which is mainly used for daily necessities, cosmetics and some luxury packaging boxes, etc., while the other is high-end matt art paper, which requires a fine and smooth surface without reflection. It is mainly used for pictorials, high-end books and magazines, etc., facing the increasing market demand for ultra-fine matte art paper. However, when the matte coated paper is wet, the powder is easy to stick and fall off, so it cannot be stored for a long time. Contents of the invention [0003] In view of this, the present invention proposes a matte coated paper with an ultra-fine surface feel and a preparation me...
