Problems solved by technology

The disadvantage of ordinary fiberboard is that there is a texture on the back, resulting in unequal surface areas on both sides of the board. After moisture absorption, the board is warped and deformed due to the difference in expansion force; the surface of hard board is hard, difficult to nail, and poor water resistance.

Embodiment 1

[0012] The bamboo and wood are pulverized, cooked with a homogenizer, and separated into bamboo fibers and wood fibers, which are dispersed in water to form a slurry with a solid component mass percentage concentration of 3% and a pH of 3.5; in the obtained slurry Add paraffin wax emulsion and polyacrylamide resin, stir the slurry for 2 minutes, then flow out the slurry on the wire mesh, vacuum suction and dewater from the back of the wire mesh, and make the slurry into a slab. Wherein, the ionicity of the paraffin wax is cationic, the polyacrylamide resin contains a monomer with a cationic group and a monomer with an anionic group in a molar ratio of 6:4, and the molecular weight is 1.8-2 million, Ionicity is amphoteric. In addition, the paraffin wax was added so that its solid content was 0.3% by mass relative to the total solid content of the conjugate fibers, and the polyacrylamide resin was added so that its solid content was 0.2% by mass relative to the total solid conte...

Embodiment 2

[0014] The bamboo and wood are pulverized, cooked with a homogenizer, and separated into bamboo fibers and wood fibers, and dispersed in water to form a slurry with a solid content mass percentage concentration of 4% and a pH of 4; in the obtained slurry Add paraffin wax emulsion and polyacrylamide resin, stir the slurry for 2 minutes, then flow out the slurry on the wire mesh, vacuum suction and dewater from the back of the wire mesh, and make the slurry into a slab. Wherein, the ionicity of the paraffin wax is cationic, the polyacrylamide resin contains monomers with cationic groups and monomers with anionic groups in a molar ratio of 4:6, and the molecular weight is 1.8-2 million. Ionicity is amphoteric. In addition, the paraffin wax was added so that its solid content was 0.5% by mass relative to the total solid content of the conjugate fibers, and the polyacrylamide resin was added so that its solid content was 0.4% by mass relative to the total solid content of the conju...

Abstract

The invention discloses a composite fiber artificial board and a manufacturing method thereof. The composite fiber artificial board is formed by bamboo fibers, wood fibers, polyacrylamide resin and paraffin; ionicity of the polyacrylamide resin is bisexual, according to the molar ratio being 6.5:2-2:6.5, a monomer with a cationic basic group and a monomer with an anionic basic group are contained, the molecular weight ranges from 800 thousands to 3000 thousands, and the ionicity of the paraffin is the positive ion. In addition, according to the manufacturing method of the composite fiber artificial board, slurry is prepared according to the manner that the solid component mass percent concentration ranges from 3% to 4%, and the pH ranges from 3 to 5; and only the polyacrylamide resin and the paraffin are added into the slurry. The static bending intensity and the tensile strength of the composite fiber artificial board reach and even exceed those of a natural wood board, the composite fiber artificial board can completely replace the natural wood board, and even can replace a bakelite board and a plastic board, the environment-friendly degree is high, and the water resistance is good.

Description

technical field [0001] The invention relates to a composite fiber man-made board and a manufacturing method thereof. Background technique [0002] Fiberboard, also known as density board, is a man-made board made of wood fiber or other plant fiber as raw material and applying urea-formaldehyde resin or other suitable adhesives. Adhesives and / or additives may be applied during the manufacturing process. Fiberboard has the advantages of uniform material, small vertical and horizontal strength difference, not easy to crack, etc., and is widely used. The disadvantage of ordinary fiberboard is that there are reticulated patterns on the back, resulting in unequal surface areas on both sides of the board. After moisture absorption, the board is warped and deformed due to the difference in expansion force; the surface of the hard board is hard, nailing is difficult, and water resistance is poor. With the improvement of people's living standards, people pay more and more attention ...
