Abstract
The invention discloses a preparation method of an antibacterial medium-density fiberboard by recycling wood chips, which aims to reduce the dosage of an adhesive in the production of boards, reduce the release of formaldehyde in use, ensure the strength of the boards, meet the use requirement, and further reduce the cost.
Description
Technical Field
The invention belongs to the technical field of artificial board processing, and relates to a manufacturing method of an antibacterial fiberboard, in particular to a manufacturing method for recycling wood chips to produce an antibacterial medium-density fiberboard.
Background
At present, artificial fiber boards are widely used for boards applied to the fields of floors, door panels, furniture and the like in order to reduce cost. The artificial fiber board is produced with wood recovered leftover, plant, shell, etc. as material, and through beating into fiber, adding adhesive and additive to improve product performance, compression molding, post treatment, etc.
Because the wood fiber is loose and is not easy to press and form, a large amount of adhesive is needed to be added for bonding, and the dosage of the adhesive in the general production process can reach 10-15 percent. In the subsequent use, the residual adhesive component in the plate can continuously release formaldehyde, and the thicker the plate is, the longer the formaldehyde is released, the living environment of a user is damaged, and the potential hazard is caused to the human health.
Therefore, it is necessary to prepare a fiberboard which is more environment-friendly, has low production cost, can meet the use requirement and is more beneficial to health, such as document No. CN 114393662A, an environment-friendly medium-density fiberboard preparation method, and adopts environment-friendly soybean protein adhesive and MDI adhesive as components of the adhesive for reducing harmful gases in the board.
However, the above patent fails to reduce the amount of the adhesive, so a method for manufacturing a fiber board is required, which can ensure the strength of the board, meet the use standard of the board, and has the advantages of low adhesive consumption and convenient pressing.
Disclosure of Invention
The invention aims to provide a manufacturing method for producing an antibacterial fiberboard by wood recycling, which is more environment-friendly and simple in process, by increasing the direct bonding area of wood fibers and reducing the using amount of the adhesive in order to improve the bonding force between the wood fibers and reduce the using amount of the adhesive.
The technical scheme is as follows:
the preparation method of the antibacterial medium-density fiberboard comprises the steps of main material preparation, rinsing, filtering and drying, mixing, paving, pressing and post-processing, wherein the key steps are that after mixing, blank making is carried out, wood fibers are extruded into regular triangular prism wood blanks, a layer of mixed wood is paved to form a bottom layer of wood fiber layer during paving, a first regular triangular prism wood blank layer is paved on the bottom layer of wood fiber layer, glue is coated, a second regular triangular prism wood fiber layer is paved, and finally a layer of mixed wood fibers is covered to form a top layer of wood fiber layer, so that pressing and post-processing are carried out.
In the blank making step, the regular triangular prism wood blanks with different specifications can be manufactured according to the customized thickness and width of the plate, and the bottom side length of the preferred regular triangular prism wood blank is 1-2.5 cm and the length is 0.5-1.5 m.
Further, in the mixing step, 2 to 5 parts of adhesive are added to 95 to 105 parts of the wood fibers.
Further, the single-sided gluing amount in the gluing step is 120-200 g/m 2 。
Further, the pressure in the pressing step is 2-4Mpa and the temperature is 180-200 ℃.
Further, in the post-processing step, the fiber board is subjected to post-processing such as trimming, polishing, sanding, surface decoration layer pasting and the like according to the application of the board.
The beneficial effects are that:
in the invention, the wood fiber is firstly manufactured into a regular triangular prism wood blank, and then the subsequent steps of paving, gluing, pressing and the like are carried out. The wood fiber regular triangular prism wood blank has three side faces as main stress faces, and stress directions of the three side faces are all directed to the center, so that acting force is more concentrated, and the cohesive force among the wood fibers is increased, so that the wood fibers can be extruded into compact wood blanks when fewer adhesives are used. The triangular prism wood blank layers can be tightly attached through the two side surfaces of each triangular prism wood blank, so that the contact area and the stress area are increased. Meanwhile, the regular triangular prism wood blank layer plays a role of reinforcing ribs, so that the strength of the fiber board is increased, and the board is prevented from being broken. The fiber board manufactured by the invention has less adhesive consumption, and the performance of the board can meet the requirements.
