Problems solved by technology

[0002] Tissue printing paper refers to a type of printing paper with low weight and high bulk. Like other printing papers, during the printing process, the paper sheet will first swell and widen due to the large amount of water in the ink absorbed by the surface printing wetness. When drying, it will shrink due to a large amount of evaporation of water, which will lead to errors in printing dimensions; the fast heating and drying system matched with high-speed paper machines, because of the short drying time and high heat, will cause thin printing paper such as Increased dimensional errors due to changes in water content

Embodiment 1

[0016] A thin page printing paper coating composition, comprising the following raw materials in parts by weight:

[0017]

[0018] The core of the nano-calcium carbonate microcapsule is nano-calcium carbonate, the capsule wall is hydroxyethyl fiber, and the particle size is 1-3 microns. The mass ratio of the core material and the wall material of the nano-calcium carbonate microcapsule is 80:20. The surface of ethyl cellulose is coated with a film layer with a thickness of 3nm and a degree of polymerization of 3000 glucose molecules.

[0019] Taking the preparation of the coating composition as an example below, its preparation method and application method are as follows:

[0020] Take 20g of hydroxyethyl cellulose, apply a layer of glucose molecular film on its surface by solution method, control the thickness of the coating to 3nm, and then prepare it into an ethanol solution with a mass fraction of 20%, add 80g of nano-calcium carbonate particles to form a stable suspe...

Abstract

The invention provides a yoshire printing paper coating composition. The yoshire printing paper coating composition comprises 40-65 parts of nanometer calcium carbonate microcapsules, 1-0.5 parts of microcrystalline cellulose, 30-50 parts of starch, 10-15 parts of a lubricant and 0.3-1 part of a dispersant. The yoshire printing paper coating composition improves strength and stiffness, reduces a size error in a printing process and provides better printing adaptability for a yoshire printing paper.

Description

technical field [0001] The invention patent belongs to the field of papermaking chemicals, and in particular relates to a coating composition for thin page printing paper. Background technique [0002] Tissue printing paper refers to a type of printing paper with low weight and high bulk. Like other printing papers, during the printing process, the paper sheet will first swell and widen due to the large amount of water in the ink absorbed by the surface printing wetness. When drying, it will shrink due to the large amount of water evaporation, which will lead to printing size errors; the fast heating and drying system matched with the high-speed paper machine, because the drying time is short and the heat is large, it will cause thin printing paper. Dimensional errors due to changes in water content increase. Contents of the invention [0003] The present invention aims at the above-mentioned problems, proposes a kind of thin page printing paper coating composition, this ...
