Problems solved by technology

The quality of low-grade decorative paper products is unstable, and the color fastness to light is generally poor, generally at level 2~3, with low covering performance, poor printing performance and batch stability, especially the color stability, and the color difference between batches is large
Moreover, the decorative base paper currently used as a decorative material has the problem of excessive paper basis weight in order to ensure higher strength ordinary sheets. The paper basis weight of decorative base paper is generally 90~130g / m 2
The base paper has a large basis weight, resulting in high production costs
[0003] The high-permeability ultra-black decorative base paper of the present invention is a high-grade product of decorative base paper, which can replace the ordinary black decorative base paper currently sold. The ordinary black decorative base paper has poor permeability during dipping processing, and the color becomes gray and black after pressing. Not enough, the pattern is uneven during printing and the color is not bright, and the ordinary black decorative base paper produced by the current process has always had the problem of white dust on the surface of the black paper
No good solution has been found at home and abroad, and there are no relevant literature reports

Embodiment 1

[0037] (1) Bleached coniferous pulp and bleached hardwood pulp are added to a pulper equipped with 40°C pulping water at a mass ratio of 1:4 to fully crush them, and when the water temperature drops to 28°C while pulping, add pulp Black pigment (Diresul Black RDT-KAS.CN Liq) with a mass of 25% of the raw material; after reducing the beating degree of the bleached wood pulp to 32°SR, and the mass concentration reaches 4%, pump it into the crushing tank for standby.

[0038] (2) Dilute the kaolin, which accounts for 15% of the mass of the slurry, to a mass concentration of 70%, fully stir it with a high-speed agitator, and then put it into the above-mentioned crushing tank. After mixing and stirring evenly, adjust the pH value of the slurry in the pulping tank to 9.

[0039] (3) Pump the slurry in the crushing tank into the filling tank, adjust the pH value of the slurry in the filling tank to 7, add a coloring agent accounting for 1.5‰ of the slurry mass in the slurry, stir well...

Embodiment 2

[0046] (1) Bleached coniferous pulp and bleached hardwood pulp are added to a pulper equipped with clear water for pulping at 40°C according to the mass ratio of 1:4.2, and fully crushed. At the same time, add pulp when the water temperature drops to 27°C The black pigment of 26% of material quality; after reducing the percussion degree of bleached wood pulp to 32 ° SR, and the mass concentration reaches 4%, it is pumped into the pulping tank for standby.

[0047] (2) Dilute the kaolin that accounts for 13% of the mass of the slurry to a mass concentration of 68%, fully stir it with a high-speed agitator, and then put it into the above-mentioned crushing tank, and adjust the pH value of the slurry in the pulping tank to 9 after mixing and stirring evenly .

[0048] (3) Pump the slurry in the crushing tank into the filling tank, adjust the pH value of the slurry in the filling tank to 7, add a colorant accounting for 1~2‰ of the slurry mass in the slurry, stir well and then add...

Embodiment 3

[0055] (1) Bleached coniferous pulp and bleached broad-leaved pulp are added to a pulper equipped with clear water for pulping at 42°C at a mass ratio of 1:3.8 and fully crushed. At the same time as pulping, add pulp when the water temperature drops to 28°C Black pigment with 30% mass of raw material; reduce the degree of percussion of bleached wood pulp to 32°SR, and pump it into the pulping tank after the mass concentration reaches 4%.

[0056] (2) Dilute kaolin, which accounts for 17% of the mass of the slurry, to a mass concentration of 71%, fully stir it with a high-speed agitator, and then put it into the above-mentioned crushing tank. After mixing and stirring evenly, adjust the pH value in the pulping tank to 9.

[0057] (3) Pump the slurry in the crushing tank into the filling tank, adjust the pH value in the filling tank to 7, add a coloring agent accounting for 1.8‰ of the slurry quality into the slurry, stir evenly, and then add 125‰ of the slurry quality. Strength...

Abstract

The invention relates to high-permeability super black decorated base paper and a preparation method of the high-permeability super black decorated base paper, and belongs to the technical field of decoration base paper. The preparation method is characterized by comprising the following steps: taking pulp mixed from bleached softwood pulp and bleached hardwood pulp according to the mass ratio of 1:(3.6-4.4) as a main raw material; reducing the beating degree of bleached wood pulp to 32 SR, enabling the mass concentration to reach 4%, and then pumping into a repulping pond for later use; directly adding a black pigment to the repulping pond, wholly substituting kaoline for titanium dioxide to prepare the decorated base paper with a black and shiny color, the fluorescent whiteness of 6%-8%, the basis weight of 70-90g / m<2>, the ash content of 10%-15%, the wet strength of 6.5-9N, the dry strength of 35-50N, the water absorption of 20-35mm / 10 minutes and the air permeability of 15-20s / 100ml. The high-permeability super black decorated base paper disclosed by the invention has the advantages of uniformity in coloring, good covering power, high air permeability, low basis weight and high paper output ratio; a processed decorating plate is high in stereoscopic impression, pure and bright in color and luster, green and environmental-friendly without white patterns.

Description

technical field [0001] A high-permeability ultra-black decorative base paper and a preparation method thereof belong to the technical field of black decorative base paper. Background technique [0002] Decorative base paper is a kind of decorative material developed with the rapid development of my country's wood-based panel industry and furniture manufacturing industry. After decades of development, decorative paper products have different textures and colors, and their properties such as wear resistance, heat resistance, scratch resistance, cigarette burning resistance, and pollution resistance are superior to those of wood-based panels. The board has an obvious protective effect. The quality of low-end decorative paper products is unstable, and the color fastness to light is generally poor, generally in the 2~3 level, with low hiding performance, poor printing performance and batch stability, especially the color stability, and the color difference between batches is lar...
