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 composite artificial board manufactured by a method according to an embodiment of the present invention, and as shown in fig. 1, the present invention provides a method for manufacturing a composite artificial board, where the composite artificial board includes a first substrate layer 1 and a second substrate layer 2 that are integrally hot-pressed, 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 chopped carbon fibers mixed in plant fibers by 5-8 wt%, the reinforcing layer 3 includes a conductive mesh carbon fiber fabric, and the method includes the following steps,
step A, preparing wood or plant raw materials into dry fibers, adding 5-8% of chopped carbon fibers according to the weight ratio, and stirring and mixing;
in the invention, firstly, wood or plant raw materials are made into dry fibers by the prior art through chipping, screening, washing, hot grinding, glue mixing and drying, then chopped carbon fibers with the weight of 5-8% of that of the dry fibers are added according to the weight of the dry fibers, and stirring is carried out by using stirring equipment to uniformly mix the fibers.
B, paving a first layer of plate blank by using the mixed 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;
because the reinforcing layer 3 of the composite artificial board is arranged between the first substrate layer 1 and the second substrate layer 2, the invention has the biggest difference from the prior art that the prior art firstly manufactures the board blank into the fiberboard, and then composites the reinforcing material on the surface of the fiberboard in a hot pressing mode and the like. In the composite artificial board provided by the invention, the reinforcing layer 3 in the composite artificial board is integrally hot-pressed and molded with the first base material layer 1 and the second base material layer 2 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 composite artificial 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 wrapping edges on the two sides of the conductive carbon fiber mesh fabric can be compounded into the composite artificial board, but the width of the geotextile wrapping edges is small, so that the performance of the composite artificial board cannot be affected. The part of the conductive carbon fiber mesh fabric extending out of the integral plate blank in the longitudinal direction is cut off only after the composite artificial board is manufactured.
And C, carrying out hot pressing on the integral plate blank finished in the step B to finish the manufacturing of the composite artificial board.
The reinforcing layer 3 is made of conductive carbon fiber mesh fabric, so that the comprehensive performance of the composite artificial board is improved, and simultaneously, after the composite artificial board is manufactured, the reinforcing layer 3 can be electrified and heated from the interior of the composite artificial board, so that the formaldehyde release of the composite artificial board is accelerated.
The first substrate layer 1 and the chopped carbon fibers in the second substrate layer 2 can further improve the comprehensive performance of the artificial fiberboard, for example, when the composite artificial board is in a high-temperature environment, the chopped carbon fibers of the first substrate layer 1 and the second substrate layer 2 can effectively avoid the deformation of the composite artificial board.
The invention provides a manufacturing method of a composite artificial board, which is characterized in that a reinforcing layer made of conductive carbon fiber mesh fabric is embedded and compounded in a man-made fiberboard, so that the conductive carbon fiber mesh fabric is paved between two layers of board blanks in the manufacturing process of the man-made fiberboard 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 composite artificial board can be produced by using only one production line, the comprehensive performance of the man-made fiberboard can be greatly improved, and the production cost can be reduced.
