Problems solved by technology

[0005] In the prior art, the disadvantage of fiberboard is that there is a texture on the back, which causes the surface area of ​​the two sides of the board to be unequal, and the board is warped and deformed due to the difference in expansion force after moisture absorption; the surface of the hard board is hard, difficult to nail, and poor in water resistance.
In addition, the fiberboard in the prior art has a single function, which cannot meet the needs of the market for building materials with multiple functions.

Embodiment 1

[0043] A kind of preparation method of coconut charcoal fiber plate, comprises the steps:

[0044] In terms of parts by mass, 10 parts of low-melting point sheath-core composite fibers, 5 parts of spiral three-dimensional crimped hollow fibers and 50 parts of coconut charcoal fibers are mixed and opened by an opener and stirred evenly, and then combed into bundles by a carding machine. Then, it is laid into a net shape by a net-laying machine, and the fiber single piece with the required thickness is shaken out by the screen, and then transported by the conveyor belt to the compressible hot air penetration machine for the low-melting point skin-core composite fiber and the spiral three-dimensional crimped hollow fiber. Baking with coconut charcoal fiber, the temperature of the compressible hot air penetration machine is 200 ℃, when the melting point of the low-melting point skin-core composite fiber is reached, the raw material fibers are fused with each other to form a board, ...

Embodiment 2

[0046] A kind of preparation method of coconut charcoal fiber plate, comprises the steps:

[0047] In terms of mass parts, 10 parts of low-melting point type skin-core composite fibers, 5 parts of spiral three-dimensional crimped hollow fibers and 50 parts of coconut carbon fibers were divided into 2 groups, and each group was mixed and opened by an opener and stirred evenly, and then It is combed into bundles by carding machine, and after mixing, it is laid into a net shape by a web lapper and shaken to obtain a single fiber sheet of the required thickness, and then transported by a conveyor belt to a compressible hot air penetration machine for low-melting point leather. The core composite fiber, spiral three-dimensional crimped hollow fiber and coconut charcoal fiber are baked. The temperature of the compressible hot air penetration machine is 200 ℃. Finally, the board is formed, and the obtained board is compressed and shaped by a compressible hot air penetration machine, ...

Embodiment 3

[0049] A kind of preparation method of coconut charcoal fiber plate, comprises the steps:

[0050] In terms of parts by mass, 15 parts of low-melting point sheath-core composite fibers, 10 parts of spiral three-dimensional crimped hollow fibers and 50 parts of coconut charcoal fibers were mixed and opened by an opener for 3 times and stirred evenly, and then combed by a carding machine. When the low-melting-point sheath-core composite fiber, the spiral three-dimensional crimped hollow fiber and the coconut charcoal fiber pass through the opening machine and the carding machine, the dust and stones in each raw fiber are simultaneously removed by the dust collector. Impurities; the obtained raw materials are then paved into a net shape by a net-laying machine and shaken to obtain a single fiber sheet of the required thickness, and then transported by a conveyor belt to a compressible hot air penetration machine for low-melting point skin-core composite fibers, spiral The three-d...

Abstract

The invention provides a coconut carbon fiberboard and a preparing method thereof. The coconut carbon fiberboard is mainly prepared from low melting point type skin-core composite fibers, spiral three-dimensional curled hollow fibers and coconut carbon fibers through the steps of loosening, combing, mesh paving, hot air compressing, rolling, cutting and the like, wherein based on parts by mass, the low melting point type skin-core composite fibers, the spiral three-dimensional curled hollow fibers and the coconut carbon fibers respectively account for 10-30 parts, 5-20 parts and 50-80 parts. The obtained coconut carbon fiberboard is natural, environment-friendly, odorless, formaldehyde-free, temperature-different-resistant and deformation-resistant, can be more effectively used for long time, is even in thickness, great in sound insulating effect, great in tenacity and high in compression resistance, and has the advantages of keeping heat, absorbing humidity, removing smell, removing formaldehyde and the like. The preparing method of the coconut carbon fiberboard is simple in technology, can carry out specified-quantity production according to requirements, is particularly suitable for massive production and is favorable to saving energy consumption.

Description

technical field [0001] The invention relates to the field of building materials, in particular to a coconut charcoal fiber board and a preparation method thereof. Background technique [0002] Fiberboard is a wood-based panel made by interweaving lignocellulosic fibers and utilizing their inherent adhesive properties. Adhesives and / or additives may be applied during the manufacturing process. [0003] 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 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 has a wide range of uses. It takes about 2.5-3 cubic meters of wood to make 1 cubic meter of fiberboard, which can replace 3 cubic meters of sawn timber or 5 cubic meters of logs. The development ...
