[0035] (2) Preparation of filler: Pour the weighed water and titanium dioxide into the frosted disperser, and add the dispersant sodium hexametaphosphate. The amount of the dispersant added is 0.4%-1% of the mass of the titanium dioxide, the speed of the mixer is set at 20000-25000r / min, and the constant speed disperses for about 40-60min. Finally, a solution with a titanium dioxide concentration of 1%-10% is prepared.

[0036] ⑶Mixing of slurry: Firstly, the weighed pulp is fluffed, the speed of the standard fluffing machine is set to 10000-20000r / min, and the time is set to 5-10min. Stir the decomposed pulp under a constant speed mixer at a speed of 800-1500r / min, then add the filler titanium dioxide solution to the pulp solution for mixing, and add additives PAM, PAE and aluminum sulfate. The dry weight of the added titanium dioxide is 20%-40% of the dry weight of the pulp. After adding the filler, stir for 3-5 minutes. The dry weight of PAE is 1%-5% of the dry weight of t...

Abstract

The invention relates to a manufacturing method of a coating decoration base paper based on gravure. When the decoration base paper is manufactured with pulp, the fillers with different ratio are added; after manufacturing with pulp, the manufactured decoration base paper is coated, dried, calendered and printed by coatings which are prepared by different prescriptions. The manufacturing method comprises the following steps of (1) manufacturing of the decoration base paper with pulp; (2) preparation of the coatings; (3) coating of the decoration base paper in step (1) by the coatings in step (2), and drying and calendering of the coated decoration base paper. The manufacturing method has the advantages that the defect of decreasing of the paper strength due to large filling amount of fillers in the traditional decoration base paper is overcome, the condition of a large loss amount of fillers due to large filling amount and insufficient retention rate of the traditional decoration base paper in the manufacturing process is reduced, and the cost is reduced; by combining with the coating technique, the surface coating suitable for the gravure is formed, so as to reach the purpose of improving the property of gravure.

Description

technical field [0001] The invention relates to a decorative base paper and a manufacturing method thereof, in particular to a coated decorative base paper based on gravure printing and a manufacturing method thereof. [0002] technical background [0003] Decorative base paper is a special industrial paper with good development prospects, mainly used in the surface decoration of wood-based panels. In recent years, with the progress of society, human beings have become more and more aware of environmental protection, and have paid more and more attention to the protection of forest resources. Wood-based panels are widely used, such as wooden floors, cabinet furniture, etc., and are an excellent wood substitute. Because of the sharp increase in demand for wood-based panels, the demand for decorative base paper for surface decoration is also increasing. The quality of decorative base paper determines the quality of wood-based panel surface decoration and the quality of wood-ba...
