Problems solved by technology

[0005] In the prior art, ordinary water-soluble phenolic resin glue or low-molecular-weight phenolic resin glue or low-molecular-weight melamine resin glue is used to impregnate wood under normal pressure, and then compacted. Poor, low production efficiency, and poor antibacterial and flame retardant properties

Embodiment 1

[0037] A method for preparing a surface compacted plate, comprising the steps of:

[0038] (1) wood is processed into a plate with a thickness of 20mm, and dried to a moisture content of 25wt%;

[0039] (2) Place the dried plate between the two pressure rollers of the roller press and carry out horizontal grain radial rolling, and the thickness compression rate of the plate when passing through the pressure roller is controlled at 20%, that is, the thickness of the plate is compressed to 16mm;

[0040] (3) The plate after the rolling process is completely immersed in the phenolic resin solution for 6 hours;

[0041] (4) The soaked plate is subjected to spray steam softening treatment, and the softening temperature is controlled at 130°C for 40 minutes;

[0042] (5) Put the softened plate in a hot press for compression, the compression rate is controlled at 30% (that is, the thickness of the plate is compressed to 14mm), the hot pressing temperature is 170°C, the highest unit ...

Embodiment 2

[0050] It is basically the same as in Example 1, except that the flame retardant is obtained by stirring and mixing evenly triphenyl phosphate and triethyl phosphate at a mass ratio of 1:1.

Embodiment 3

[0052] It is basically the same as Example 1, except that the flame retardant is obtained by stirring and mixing evenly tris(2-chloroethyl) phosphate and triethyl phosphate at a mass ratio of 1:1.

Abstract

The invention discloses a preparation method of a surface compaction plate. The preparation method comprises the following steps: (1) wood is processed into a plate with the thickness being 10-25mm, and is dried till the water ratio reaches 20-30wt%; (2) the dried plate is arranged between two compression rollers of a roller press for cross grain radial rolling, and the thickness compression ratio of the plate passing the compression rollers is controlled at 10-30%; (3) the plate after the rolling treatment is soaked in phenolic resin liquid for 1-10h; (4) the soaked plate is subjected to steam-injection softening treatment; and (5) the softened plate is arranged in a hot press for compression. According to the preparation method of the surface compaction plate, the produced plate is high in surface layer density and strength and is not prone to deform; a technology is simple, no treatment on man-made forest soft wood is required in a sealed container, and the production efficiency is high; processing parameters are definite and the operability is high; and the surface compaction plate is light in color, has excellent flame retardant and antibacterial properties, and can directly act as materials of furniture and interior decoration.

Description

technical field [0001] The invention relates to the technical field of wood processing, in particular to a method for preparing a surface compacted board. Background technique [0002] Wood is the lignified tissue of plants capable of secondary growth, such as trees and shrubs. After the primary growth of these plants ends, the vascular cambium in the rhizome becomes active, developing bast outward and wood inward. Wood is the general term for plant tissues that develop inwardly from the vascular cambium, including xylem and parenchyma rays. Wood plays a great supporting role in human life. According to the different properties and characteristics of wood, people use them in different ways. [0003] A plank is a plank made of whole wood. Durable and with a natural grain, these panels are an excellent choice for decoration. This type of plank is expensive, and the plank is generally classified according to the real name of the plank, and there is no uniform standard spec...
