Problems solved by technology

While the coated paper in the prior art improves the printing gloss, it often reduces the ink absorption; on the contrary, when the ink absorption is improved, the printing gloss often decreases, and the printing gloss of the coated paper cannot be realized. Improve the degree and ink absorbency at the same time, affect the use of coated paper

Abstract

The invention relates to a processing method of high-luminosity mothproof coated paper, and belongs to the technical field of coated paper processing. The technical problem that the printing luminosity and the ink absorbency of coated paper in the prior art cannot be improved at the same time is solved. Processing of the high-luminosity mothproof coated paper is achieved through the following three steps: preparing raw material paper, preparing a coating liquid and preparing the coated paper, and the coating liquid is prepared from a sizing material, starch modified polyvinyl formal, talcum powder, titanium dioxide, calcium carbonate, turpentine oil, Artemisia argyi-tea tree mixed extract, nanometer aluminum oxide, microcrystalline cellulose, a dispersant and auxiliary agents. The starch modified polyvinyl formal, nanometer aluminum oxide and microcrystalline cellulose are added into the coating liquid, so the printing luminosity and the ink absorbency of the coated paper are improved;and the mutual synergistic effects of the turpentine oil and the Artemisia argyi-tea tree mixed extract improve the mothproof property and the practicability of the coated paper.

Description

technical field [0001] The invention relates to the technical field of coated paper processing, more specifically, it relates to a method for processing high-gloss mothproof coated paper. Background technique [0002] Coated paper is a high-grade printing paper made of base paper coated with white paint. It is mainly used to print covers and illustrations of high-end books, color pictures, various exquisite product advertisements, samples, product packaging, trademarks, etc.; after coating white paint on the surface of base paper, the surface printability of coated paper can be improved. While the coated paper in the prior art improves the printing gloss, it often reduces the ink absorption; on the contrary, when the ink absorption is improved, the printing gloss often decreases, and the printing gloss of the coated paper cannot be realized. The degree and ink absorbency are improved at the same time, which affects the use of coated paper. Contents of the invention [00...
