Abstract

The invention provides a preparation method of plant functional coated paper for children's reading materials. The preparation method comprises the steps of pulping, pulp beating, reboiling, secondary pulping, raw paper preparation, sizing and post-treatment. According to the prepared coated paper, the strength of finished paper is improved, the coated paper is not prone to being torn by children, the dry strength ranges from 6.6 m / s to 7.0 m / s, and the wet strength ranges from 9.7 m / s to 10.2 m / s; good bending resistance is achieved, the transverse folding strength ranges from 3594 times to 3780 times, and the longitudinal folding strength ranges from 2357 times to 2518 times; and the antibacterial effect is good, the inhibition rate on staphylococcus aureus is 97.1-97.5%, the inhibition rate on escherichia coli is 94.5-95.8%, and the inhibition rate on typhoid bacillus is 95.7-96.3%.

Description

technical field [0001] The invention relates to a preparation method of coated paper for plant functional children's books, belonging to the field of coated paper. Background technique [0002] Coated paper is coated with a layer of paint on the base paper, so that the paper has good optical properties and printing performance. Its main uses are: publishing paper for printing magazines, books, etc., and printing paper for trademarks, packaging, catalogs, etc. It is mainly made by coating the coating liquid with pigment and binder as the main components on the base paper, and drying it. However, according to the coating amount and the processing method of the coated paper, it is classified as cast coated coated paper (high Glossy printing paper, Cast-coated paper), coated art paper (artpaper, cardstock, double-coated paper), coated paper (coated paper), lightweight coated paper (Lightweightcoatedpaper), etc. These coated papers are printed in multiple colors or monochrome, ...
