Problems solved by technology

[0004] Although the physical properties of high-density fiberboard are excellent, the higher the density, the greater the weight of the board, which makes the products made of high-density fiberboard heavier and difficult to handle. It does not meet the practical application of lightweight, and there is still room for improvement.

Embodiment 1

[0047] A kind of decorative fiberboard, refer to figure 1 as well as figure 2 , including a high-density plate body 1 pressed by wood fibers, the plate body 1 is flat, and a number of densely distributed microholes 11 are arranged in the plate body 1, and a number of short glass fibers 111 are connected to the microholes 11.

[0048] The microhole 11 is spherical, and the short glass fiber 111 runs through the microhole 11 randomly and both ends are connected with the wood fiber of the solid part near the microhole 11 , and the microhole 11 is reinforced by the short glass fiber 111 .

[0049] The surface of the board body 1 is coated with a waterproof coating (not shown in the figure).

preparation Embodiment 1

[0051] A method for preparing decorative fiberboard in Example 1, with reference to image 3 , including the following specific steps:

[0052] S001 pretreatment foaming agent, as follows:

[0053] Inject glue into the stirring tank and heat it to 35°C, then put the short glass fibers into the stirring tank and stir, so that all the short glass fibers are adhered to the glue, and then put the foaming agent carbonic acid into the high-speed roller mixer Sodium bicarbonate, and then put the short glass fiber adhered with glue into a high-speed roller mixer to stir, so that the sodium bicarbonate powder adheres to the short glass fiber, then discharge the sodium bicarbonate powder and the short glass fiber and sieve, The screened short glass fiber adhered with sodium bicarbonate powder was dried for later use.

[0054] By heating the glue to 35°C, the polymer chains in the glue are easier to move, which makes the glue easier to stir, and at the same time makes it easier for the...

Embodiment 3

[0080] A method for preparing decorative fiberboard in Example 1, the difference from Example 2 is:

[0081] The length of short glass fiber in S001 is 2mm.

[0082] Since the length of the short glass fiber is 2 mm, it is avoided that too much foaming agent is attached due to the short glass fiber being too long, resulting in too large micropores formed in the decorative fiberboard when the foaming agent foams, so as to avoid a large local strength of the decorative fiberboard. decline.

Abstract

The invention relates to the field of the processing of wood products. Aiming at the problem that a high-density fiberboard has a high weight, the invention provides a decorative fiberboard and a preparation method thereof. The decorative fiberboard can be used for decreasing the weight of a board body and is used for maintaining physical performance. According to the technical scheme, the decorative fiberboard comprises a high-density board body, wherein the high-density board body is formed by compressing wood fibers; a plurality of densely distributed micropores are formed in the board body; short glass fibers, two ends of each of which are connected into the board body, are arranged in the micropores. The preparation method of the decorative fiberboard comprises the following steps ofmixing a solid foaming agent with the short glass fibers, bonding, fixing, blending the wood fibers into a pretreated foaming agent, blending the wood fibers into an adhesive and a curing agent, loading into a die, laminating, cooling, carrying out surface treatment, spray-coating a waterproof coating, and polishing. Through forming the plurality of densely distributed micropores in the high-density board body, the short glass fibers, two ends of each of which are connected into the board body, are arranged through the micropores to maintain the strength at the micropores; the weight of the fiberboard is decreased, and further, the physical performance is maintained at a high level.

Description

technical field [0001] The invention relates to the field of wood product processing, more specifically, it relates to a decorative fiberboard and a preparation method thereof. Background technique [0002] Fiberboard, also known as density board, is a wood-based panel made of wood fiber or other vegetable fiber, applied with urea-formaldehyde resin or other suitable adhesives. Adhesives and (or) additives can be applied during the manufacturing process. Fiberboard has uniform material, vertical and horizontal It has the advantages of small strength difference, not easy to crack, etc., and has a wide range of uses. It takes about 2.5 to 3 cubic meters of wood to manufacture 1 cubic meter of fiberboard, which can replace 3 cubic meters of sawn timber or 5 cubic meters of logs. The development of fiberboard production is an effective way for the comprehensive utilization of wood resources. way. [0003] With its excellent physical properties, high-density fiberboard is compat...
