preparation example Construction

[0039] The invention provides a kind of preparation method of fiberboard, specifically comprises the following steps:

[0040] (1) Material selection: choose wood pulp as fiber raw material;

[0041] (2) Suspension preparation: dissolving the binder in water, and adding the pulp raw material described in step (1), to prepare a suspension solution;

[0042] (3) Copying: Manually or mechanically pick up the fibers in the suspension solution described in step (2), and lay them in the mold layer by layer;

[0043] (4) Molding: When the fiber laid in step (3) reaches the set thickness, it is pre-pressed, dehydrated and shaped to form a slab;

[0044] (5) Curing and shaping: the slab obtained in step (4) is subjected to hot-press curing and shaping.

Embodiment 1

[0047] The present embodiment relates to a kind of preparation method of fiberboard, specifically comprises the following steps:

[0048] Step (1), material selection: wood pulp is selected as the fiber raw material.

[0049] Wood pulp is selected as the fiber raw material. During the preparation of wood pulp, lignin and other unstable substances are removed, which is beneficial to improve the anti-corrosion performance of the fiber board; at the same time, the fibers are refined, so that the stress in all directions of the fiber board obtained by hot pressing is the same , is not easy to deform, and can also make the fibers evenly contact the adhesive, the board is fully plasticized, and the waterproof and antibacterial performance is improved; in addition, in the process of pulp preparation, the formaldehyde in the wood raw material itself is also removed, which is more environmentally friendly .

[0050] Step (2), preparation of suspension: dissolving the adhesive in water...

Embodiment 2

[0069] The present embodiment provides a kind of preparation method of fiberboard, specifically comprises the following steps:

[0070] (1) Material selection: choose wood pulp as fiber raw material;

[0071] (2) Suspension preparation: dissolving the binder in water, and adding the pulp raw material described in step (1), to prepare a suspension solution;

[0072] (3) Copying: Manually or mechanically pick up the fibers in the suspension solution described in step (2), and lay them in the mold layer by layer;

[0073] (4) Molding: When the fiber laid in step (3) reaches the set thickness, it is pre-pressed, dehydrated and shaped to form a slab;

[0074] (5) Curing and shaping: the slab obtained in step (4) is subjected to hot-press curing and shaping.

[0075] Wherein, the step (3) specifically includes the following steps:

[0076] A. Pick up the fibers manually or mechanically to form wet paper;

[0077] B. Dehydrating and drying the wet paper to obtain pure fiber paper...

Abstract

The invention provides a fiberboard and a preparation method thereof. Pulp is selected as a raw material. In the process of making pulp, lignin and other unstable substances are removed to obtain relatively pure and refined fibers. The pulp is separated after papermaking. Layers are laid, and under the action of the adhesive, it is cured by heat and pressure to form a fiberboard. Among them, the removal of unstable substances such as lignin is beneficial to improve the anti-corrosion performance of the fiberboard; the fiber thinning makes the stress in all directions of the fiberboard obtained by hot pressing the same, and it is not easy to deform, and it can also make the fiber evenly contact with the adhesive. Fully plasticized to improve waterproof and antibacterial performance; layered laying makes the final board have a layered network fiber structure, which increases the elasticity of the board and the convenience of surface repair.

Description

technical field [0001] The invention relates to a fiberboard and a preparation method thereof, in particular to a high-strength fiberboard with antibacterial and waterproof functions 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 and applied with urea-formaldehyde resin or other suitable adhesives. Adhesives and / or other additives may be applied during the manufacturing process. Fiberboard has the advantages of uniform material, small vertical and horizontal strength difference, and not easy to crack, but it also has the following disadvantages: [0003] 1. It is not moisture-proof, it will swell when it sees water, and the plate will warp and deform due to the difference in expansion force after moisture absorption; [0004] 2. Because the lignin in the raw material contains nutrient-rich ingredients, the board will become moldy after absorbing moist...
