Detailed Description
In order to more clearly understand the technical features, objects, and effects of the present invention, embodiments of the present invention will now be described with reference to the accompanying drawings. Wherein like parts are given like reference numerals.
Fig. 1 is a schematic structural diagram of a fiberboard manufactured by a method according to an embodiment of the present invention, and referring to fig. 1, the present invention provides a method for manufacturing a fiberboard, the fiberboard includes a first substrate layer 1 and a second substrate layer 2 which are integrally formed by hot pressing, a reinforcing layer 3 is disposed between the first substrate layer 1 and the second substrate layer 2, the first substrate layer 1 and the second substrate layer 2 are made of wood fibers or plant fibers, the reinforcing layer 3 includes a conductive carbon fiber mesh fabric, the method includes the following steps,
step A, preparing wood or plant raw materials into dry fibers;
in the invention, firstly, the wood or plant raw materials are made into dry fibers by the prior art through chipping, screening machine, water washing, hot grinding machine, glue mixing and drying.
B, paving a first layer of plate blank by using the fiber material in the step A, paving a conductive carbon fiber mesh fabric on the first layer of plate blank, and paving a second layer of plate blank on the conductive carbon fiber mesh fabric; the first layer of plate blank and the second layer of plate blank tundish clamp the conductive carbon fiber mesh fabric to form an integral plate blank;
the reinforcing layer 3 of the fiberboard is arranged between the first substrate layer 1 and the second substrate layer 2, so the invention is the biggest difference from the prior art that the prior art firstly manufactures a board blank into the fiberboard, and then the surface of the fiberboard is compounded with the reinforcing material by a hot pressing mode and the like. In the fiberboard provided by the invention, the reinforcing layer 3 inside the fiberboard is integrally formed with the first base material layer 1 and the second base material layer 2 in a hot-pressing manner in the board manufacturing process. That is, in the mat laying, the fiber blank produced in step a is laid in two steps.
Firstly, a blank for forming the second substrate layer 2, i.e., a first-layer slab, is laid, then, the blank is stopped from being poured, the conductive carbon fiber mesh fabric is laid on the blank for forming the second substrate layer 2, and then, a blank for forming the first substrate layer 1, i.e., a second-layer slab, is continuously laid on the conductive carbon fiber mesh fabric, so that the laying of the whole slab is completed.
The thicknesses of the first layer blank and the second layer blank may be laid according to the final thicknesses of the first substrate layer 1 and the second substrate layer 2. First substrate layer 1 with the thickness of second substrate layer 2 is greater than 3mm, can ensure like this at the hot pressing complex in-process, is used for forming first substrate layer 1 with the slab of second substrate layer 2 can be fine with form the compound as an organic whole of the conductive carbon fiber mesh fabric of enhancement layer 3, the bonding is firm.
In order to ensure that the conductive carbon fiber mesh fabric can be tightly connected with the first substrate layer 1 and the second substrate layer 2 by using the bonding glue in the fiber blank produced in step a, the conductive carbon fiber mesh fabric may be a hollow mesh fabric woven by conductive carbon fiber yarns and wrapped with geotextile around the hollow mesh fabric, for example, fig. 2 is a schematic manufacturing principle diagram of the fiber board shown in fig. 1, in which a dotted line represents the size of a whole slab, a solid line represents the conductive carbon fiber mesh fabric, see fig. 2, the whole slab has a longitudinal dimension of L1 and a transverse dimension of W1, the conductive carbon fiber mesh fabric has a longitudinal dimension of L2 and a transverse dimension of W2, the mesh size of the conductive carbon fiber mesh fabric may be 5x5-10x10mm, and the width of W3 of the geotextile wrapping may be 8-15mm, the size of the conductive carbon fiber mesh fabric is larger than that of the whole plate blank in the longitudinal direction of the whole plate blank conveying direction, namely L2 is larger than L1, and is smaller than that of the whole plate blank in the transverse direction, namely W2 is smaller than W1, so that the conductive carbon fiber mesh fabric does not leak from two sides of the whole plate blank in the conveying process, and the blank is not scattered before hot pressing. The width W3 of the geotextile wrapping edge can be 8-15mm, the geotextile wrapping edge is utilized, carbon fiber yarns woven into the conductive carbon fiber mesh fabric can keep the size in the laying process, and the conductive carbon fiber mesh fabric cannot be dislocated and deformed. The geotextile bordures at the two sides of the conductive carbon fiber mesh fabric can be compounded into the fiber board, but the width of the geotextile bordures is small, so that the performance of the fiber board is not affected. The portion of the conductive carbon fiber mesh fabric that extends longitudinally beyond the unitary sheet blank need only be cut away after the fiberboard is formed.
And C, carrying out hot pressing on the integral plate blank finished in the step B to finish the manufacture of the fiber plate.
The reinforcing layer 3 is made of conductive carbon fiber mesh fabric, so that the comprehensive performance of the fiberboard is improved, and meanwhile, after the fiberboard is manufactured, the reinforcing layer 3 can be electrified and heated from the interior of the fiberboard, so that the formaldehyde release of the fiberboard is accelerated.
The invention provides a method for manufacturing a fiber board, which is characterized in that a reinforcing layer made of conductive carbon fiber mesh fabric is embedded and compounded in a man-made fiber board, so that the conductive carbon fiber mesh fabric is paved between two layers of board blanks in the manufacturing process of the man-made fiber board in advance, and then the two layers of board blanks and the conductive carbon fiber mesh fabric are compounded into a whole through hot pressing, so that the fiber board can be produced by only using one production line, the comprehensive performance of the man-made fiber board can be greatly improved, and the production cost can be reduced.
