Problems solved by technology

The base paper is printed downstream, impregnated with melamine, and made into a decorative material after veneering. There are disadvantages such as the surface is not resistant to pollution, easy to fade, and not resistant to corrosion.
Ordinary ceramic tiles, cement, PVC and other traditional decorative materials have monotonous colors and old styles, which can no longer meet the requirements of modern outdoor decoration.

Embodiment 1

[0061](1) The wood pulp is hydrolyzed according to the ratio of 10% of long-fiber wood pulp and 90% of short-fiber wood pulp. The pulping concentration is 4.5%. Add 2% of iron oxide yellow 4910 pigment and put it into the pulping tank for standby ;

[0062] (2) Dilute the filler to a concentration of 50% according to the ratio of R796 to 70%, magnesium silicate to 25%, and kaolin to 5%, and stir it at a high speed for 10 minutes with a stirrer at 1000 rpm, and set aside;

[0063] (3) Put the mixture obtained in step (2) into the pulping tank obtained in step (1) and mix for 5 minutes;

[0064] (4) adjust the pH value of the slurry obtained in step (3) to 3.5 with sulfuric acid solution, and circulate for 20 minutes; then adjust the pH value to 9.5 with sodium hydroxide solution for 20 minutes;

[0065] (5) After the slurry obtained in step (4) is treated by a refiner, the degree of knocking of the slurry is controlled between 35 ° SR;

[0066] (6) Put the slurry obtained in ...

Embodiment 2

[0071] (1) Carry out hydraulic disintegration to wood pulp according to the proportion of 2% of long-fiber wood pulp and 98% of short-fiber wood pulp, and the pulping concentration is 4.8%,

[0072] Add 5% of the iron oxide yellow 4910 pigment and put it into the crushing pool for later use;

[0073] (2) Dilute the filler to 50% concentration according to the ratio of R796 to 75%, magnesium silicate to 22%, and kaolin to 3%, and stir it at a high speed for 10 minutes with a stirrer at 1000 rpm, and set aside;

[0074] (3) Put the mixture obtained in step (2) into the pulping tank obtained in step (1) and mix for 5 minutes;

[0075] (4) adjust the pH value of the slurry obtained in step (3) to 4 with sulfuric acid solution, and circulate for 20 minutes; then adjust the pH value to 9.8 with sodium hydroxide solution for 20 minutes;

[0076] (5) After the slurry obtained in step (4) is treated by a refiner, the degree of knocking of the slurry is controlled between 41 ° SR;

Abstract

The invention belongs to the technical field of papermaking, and in particular relates to overcoating base paper used for an outdoor highly-strengthened plate and a preparation method of the overcoating base paper. The base paper is prepared from the following raw materials: wood pulp, a filler, an auxiliary agent and a pigment, wherein the auxiliary agent is composed of sodium hydroxide, sulphuric acid, aluminium sulphate and a wet strength agent; and the filler is composed of titanium dioxide, magnesium silicate and kaolin. The prepared overcoating base paper used for the outdoor highly-strengthened plate provided by the invention has a good covering property, fiber distribution uniformity, fine paper surfaces, strong corrosion resistance, a high sun-proof grade, and high water washing color fastness; and after the base paper is impregnated with melamine for veneering, the base paper is impregnated into a solution with the pH of 3.5-10, and no phenomena such as blistering and deformation of the paper happen; and the sun-proof grade is 6 grade or more, and the water washing color fastness is high. The invention also provides a preparation method of the overcoating base paper usedfor the outdoor highly-strengthened plate, and the base paper has high practicability and scientific and reasonable operation, and is simple and practicable.

Description

technical field [0001] The invention belongs to the technical field of papermaking, and in particular relates to a decorative base paper for an outdoor high-strength board and a preparation method thereof. Background technique [0002] Ordinary facing paper is a kind of decorative material widely used in home decoration. The base paper is printed downstream, impregnated with melamine, and made into a decorative material after veneering. There are shortcomings such as the surface is not resistant to pollution, easy to fade, and not resistant to corrosion. Ordinary ceramic tiles, cement, PVC and other traditional decorative materials are monotonous in color and old in style, which can no longer meet the requirements of modern outdoor decoration. With the continuous development of science and technology and the continuous improvement of people's living standards, architectural decoration is developing in the direction of environmental protection, high strength and personalized...
