Detailed description of the invention
In order to there be understanding clearly to technical characteristic of the present invention, object and effect, now contrast accompanying drawing and the specific embodiment of the present invention is described.Wherein, identical parts adopt identical label.
Fig. 1 display be the structural representation of fiberboard manufactured by the method for a specific embodiment of the present invention, shown in Figure 1, the invention provides a kind of manufacture method of fiberboard, described fiberboard comprises the first substrate layer 1, second substrate layer 2 of integrated hot pressing formed, enhancement Layer 3 is provided with between described first substrate layer 1 and described second substrate layer 2, described first substrate layer 1 is wood fibre or string with described second substrate layer 2 material, described enhancement Layer 3 comprises conductive carbon fibre reticulated, described method comprises the steps
Steps A, makes dried fibres by wooden or plant material;
In the present invention, first utilize existing technique by wooden or plant material by chipping-screening machine-washing-defibrator-glue compounding and applying-drying after make dried fibres.
Step B, uses the fibre material in steps A to lay ground floor slab, then on described first time slab, lays conductive carbon fibre reticulated, then lay second layer slab on described conductive carbon fibre reticulated; Described ground floor slab and described second layer slab tundish clip described conductive carbon fibre reticulated and form overall slab;
Described enhancement Layer 3 due to described fiberboard is arranged between described first substrate layer 1 and described second substrate layer 2, therefore, the present invention and the maximum difference of prior art are also just, prior art is all first slab is made fiberboard, and then at fibreboard surface by reinforcement material in the mode compounds such as hot pressing.And fiberboard provided by the invention, the described enhancement Layer 3 of its inside is in board making process, with described first substrate layer 1 and described second substrate layer 2 integrated hot pressing formed.That is to say, when slab is laid, in steps A, the fibre blank of output is laid at twice.
First, lay the blank for the formation of described second substrate layer 2, i.e. ground floor slab, then stop toppling over blank, lay described conductive carbon fibre reticulated at the blank for the formation of described second substrate layer 2, then continue on described conductive carbon fibre reticulated, to lay the blank for the formation of described first substrate layer 1, i.e. second layer slab, so far, the laying of overall slab is completed.
The thickness of described ground floor slab and described second layer slab can be laid according to the thickness of final described first substrate layer 1 and described second substrate layer 2.Described first substrate layer 1 is greater than 3mm with the thickness of described second substrate layer 2, can ensure like this in hot pressing recombination process, slab for the formation of described first substrate layer 1 and described second substrate layer 2 can be good at being complex as a whole with the conductive carbon fibre reticulated forming described enhancement Layer 3, and bonding firmly.
In order to ensure that described conductive carbon fibre reticulated can utilize the composite joint of the adhesive glue in the fibre blank of steps A output and described first substrate layer 1 and described second substrate layer 2 enough tight, described conductive carbon fibre reticulated can be the ready-made hollow reticulated woven by conductive carbon fibre silk, and use geotextiles bound edge in its surrounding, such as, the manufacturing theory schematic diagram that Fig. 2 is the fiberboard shown in Fig. 1, in figure, dotted line represents the size of overall slab, solid line represents described conductive carbon fibre reticulated, shown in Figure 2, the longitudinal size of described overall slab is L1, lateral dimension is W1, the longitudinal size of described conductive carbon fibre reticulated is L2, lateral dimension is W2, the size of mesh opening size of described conductive carbon fibre reticulated can be 5x5-10x10mm, the width W 3 of described geotextiles bound edge can be 8-15mm, the size of described conductive carbon fibre reticulated is greater than the size of described overall slab in the longitudinal direction of described overall slab direction of transfer, that is to say that L2 is greater than L1, be less than the size of described overall slab in the horizontal, that is to say that W2 is less than W1, so just can ensure that described overall slab is in transport process, both sides can not have described conductive carbon fibre reticulated to spill, also would not blank be caused to be scattered before carrying out hot pressing.The width W 3 of described geotextiles bound edge can be 8-15mm, utilize described geotextiles bound edge, the carbon fiber wire being woven into described conductive carbon fibre reticulated can be made in process of deployment to keep size, can not be misplaced distortion, and, when laying described conductive carbon fibre reticulated, can, so that geotextiles bound edge described in holder, avoid causing damage to the grid of described conductive carbon fibre reticulated.The geotextiles bound edge of described conductive carbon fibre reticulated both sides also can be compound in described fiberboard, but due to its width less, therefore can't bring impact to the performance of described fiberboard.Described conductive carbon fibre reticulated stretches out the part of described overall slab in the vertical, only needs to excise after described fiberboard is made.
