Abstract

The invention discloses a packaging cover paper for finished ITO conductive glass products and a preparation method thereof, belonging to the technical field of packaging cover paper. The packaging cover paper is obtained by processing chemical fibers and plant fibers as main raw materials, wherein the mass percentage of chemical fibers is 5% to 15%, and the mass percentage of plant fibers is 85% to 95%. The preparation method includes processes such as raw material weighing, pulping, plant fiber purification, pulp preparation, papermaking, drying, molding, etc. Among them, the plant fiber purification process adopts a multi-stage impurity removal and purification process, which can effectively ensure the purity of the raw material slurry and improve The quality of the finished product of the packaging cover paper, the hot melt of the finished product in a high-temperature and high-humidity environment is within 0.4% to 0.6%, the ash content is within 0.8% to 1.2%, the paper has good smoothness, high tensile strength, and can be effectively It can prevent the precipitates in the material from contaminating the ITO conductive glass, so it can improve the product yield of LCD manufacturers and avoid the problem of rework.

Description

technical field [0001] The invention belongs to the technical field of packaging cover paper, in particular to a packaging cover paper for finished ITO conductive glass products and a preparation method thereof. Background technique [0002] At present, during the packaging of finished ITO conductive glass products (20 pieces / package), a protective material needs to be used on the top and bottom of each package of glass to ensure that the product quality of the upper and lower pieces of ITO conductive glass will not be affected. At present, there is no material on the market that is specially used for the upper and lower cover plates of ITO conductive glass packaging. ITO manufacturers currently use whiteboard paper or double-adhesive paper for use, but because the above two products have certain pollution, resulting in LCD manufacturers often complain to ITO manufacturers about the low yield of two pieces of ITO conductive glass per package. Therefore, ITO manufacturers ur...
