Problems solved by technology

However, when the coated paper in the prior art is in a humid environment for a long time, it is easily damaged by microorganisms and moths, which affects the use of the coated paper. Therefore, in order to increase the storage time of the coated paper, it is necessary to reduce the storage humidity, which improves the storage conditions of coated paper and increases the storage cost of coated paper

Abstract

The invention relates to a processing method of an antibacterial mothproof coated paper, and belongs to the technical field of coated paper processing. The technical problem of poor mildew-proof and mothproof performances of coated papers in the prior art is solved. The antibacterial mothproof coated paper is processed through three steps of preparing raw material paper, preparing a coating liquidand preparing the coated paper, and the coating liquid is prepared from a sizing material, starch, talcum powder, titanium dioxide, calcium carbonate, turpentine oil, a wormwood-tea tree mixed extract, a mildew-proof bactericide, a dispersing agent and additives. The mildew-proof bactericide, the turpentine oil and the wormwood-tea tree mixed extract are added into the coating liquid to improve the mildew-proof and antibacterial properties of the coated paper, and the mutual synergistic effects of the turpentine oil and the wormwood-tea tree mixed extract improve the mothproof property of thecoated paper, so that the storage condition and the storage cost of the coated paper are reduced, and the storage time of the coated paper is prolonged.

Description

technical field [0001] The invention relates to the technical field of coated paper processing, more specifically, it relates to an antibacterial and mothproof coated paper processing method. 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. However, when the coated paper in the prior art is in a humid environment for a long time, it is easily damaged by microorganisms and moths, which affects the use of the coated paper. Therefore, in order to increase the storage time of the coated paper, it is necessary to reduce the High storage humidity, which improves the storage conditions of coated paper and increases the storage co...
