In addition, in feasible program of the present invention, the thickness of two backing material plates equates or the backing material plate thickness that is provided with routing hole is greater than another piece backing material plate; The THICKNESS CONTROL of backing material plate is between 3-5mm.By the THICKNESS CONTROL of backing material plate within the scope of this, mainly to consider that cloth hole requires and the needs of above-mentioned protection against the tide or waterproof step, blocked up backing material plate, vacuum suction anti-blushing agent and waterproofing agent cannot be realized or need to expend the long time and for manufacturing vacuum needed energy, and used thin high density fiberboard, cannot implement the routing hole processing on backing material plate surface.
Step 2, between two backing material plates, evenly apply Cold-press adhesion layer 30, upper and lower two backing material plates are carried out to assembly, then carry out slab stacking, after composing and laying out neatly, carry out cold pressing treatment by preformer, the parameter of colding pressing is: the time 4-6h that colds pressing, pressure 8-10MPa; Must remove the glue of non-coated face and impurity pollution and coated face before assembly and smear excessive adhesive, slab stacks as high is controlled between 120-150mm, and adds the backing plate that thickness is 15-30mm between the pressure-acting face of preformer and slab.The selection of the parameter of colding pressing is most important for the quality of water-proof sheet material, in step 2, by adopting the parameter of reasonably colding pressing, is ensureing the strong bonded of two backing material plates, thereby makes water-proof sheet material durable in use and have a good waterproof effect.It should be noted that, cold pressing that in sheet material manufacture field, to make be at normal temperatures sheet material to be carried out to pressing without heating, is to overlay corresponding concept with hot pressing.
Step 3, the health that the substrate layer after colding pressing is carried out at least 48 hours after processing overlay described overlay coating hot pressing in the one side of described substrate layer or two-sided.
When specific implementation, in the preferred embodiments of the present invention, in described step 3, hot pressing overlays and comprises precompressed processing and hot-pressing processing, between described substrate layer and overlay coating, be evenly distributed with heat pressure adhesive glue, described heat pressure adhesive glue is coated on substrate layer surface before hot-pressing processing, described hot compression parameters is: pressure 16-18MPa, temperature 168-174 DEG C, time 27-31s; Before hot-pressing processing, also need the solid wood thick china good to assembly and substrate layer to carry out precompressed processing, precompressed parameter is: pressure 1.5-2MPa, time 20-40min.Precompressed processing makes solid wood thick china and the better combination of substrate layer, reaches smooth, proper object, overlays effect with the hot pressing of optimizing water-proof sheet material.And by adopting rational hot compression parameters, in ensureing the good laminating effect of water-proof sheet material, can be because of hot pressing temperature, overlay that time and pressure selects unreasonable and sheet material is caused to damage.
Step 4, the health that the sheet material after hot-pressing processing is carried out 1-2 days are offered the chase mortise of being convenient to sheet material construction, splicing after processing in the avris position of sheet material, make finished product.
In the preferred embodiment of the present invention, overlay coating comprises the decorative layer 22, the wearing layer 21 that are positioned at substrate layer one side, and be positioned at the balance layer 23 of substrate layer another side, balance layer 23 is positioned at the side that water-proof sheet material contacts with ground or metope, decorative layer 22 is between substrate layer 10 and wearing layer 21, decorative layer 22 is melamine dipping decorative paper, and wearing layer 21 is melamine-impregnated abrasion-proof paper, and balance layer 23 is melamine-impregnated balance paper.Wherein, melamine-impregnated abrasion-proof paper is generally transparent or semitransparent, thereby makes water-proof sheet material of the present invention in having good wear-resisting effect, does not affect the decorative effect of melamine dipping decorative paper, ensures the aesthetic appearance of whole water-proof sheet material.
In addition, what step 2 single spreading adopted is anhydrous type adhesive, and anhydrous type adhesive comprises curing agent and the adhesive of mass ratio 5:100, and the glue-spread of single spreading is 120-150g/m
2.Curing agent used and adhesive are commercially available conventional product, in the present embodiment, select the Macroplast series of products of Henkel KGaA company, and curing agent is UK3131, and adhesive is UK3463.And the control of glue-spread not only needs to ensure effectively bonding between backing material plate, and be unlikely to waste, overflow and affect the processing of sheet material.

Step 3, evenly apply Cold-press adhesion layer in the one side of not posting overlay coating of two backing material plates, upper and lower two backing material plates are carried out to assembly, then carry out slab stacking, after composing and laying out neatly, carry out cold pressing treatment by preformer, the parameter of colding pressing is: the time 4-6h that colds pressing, pressure 8-10MPa; Must remove the glue of non-coated face and impurity pollution and coated face before assembly and smear excessive adhesive, slab stacks as high is controlled between 120-150mm, and adds the backing plate that thickness is 15-30mm between the pressure-acting face of preformer and slab;
Step 4, the health that the sheet material after cold pressing treatment is carried out 1-2 days are offered the chase mortise of being convenient to sheet material construction, splicing after processing in the avris position of sheet material, make finished product;
In described step 3, hot pressing overlays and comprises precompressed processing and hot-pressing processing, between described substrate layer and overlay coating, be evenly distributed with heat pressure adhesive glue, described heat pressure adhesive glue is coated on substrate layer surface before hot-pressing processing, described hot compression parameters is: pressure 16-18MPa, temperature 168-174 DEG C, time 27-31s; Before hot-pressing processing, also need the solid wood thick china good to assembly and substrate layer to carry out precompressed processing, precompressed parameter is: pressure 1.5-2MPa, time 20-40min.
6. the preparation method of water-proof sheet material according to claim 5, it is characterized in that: described overlay coating comprises the decorative layer, the wearing layer that are positioned at described substrate layer one side, and be positioned at the balance layer of described substrate layer another side, described balance layer is positioned at the side that water-proof sheet material contacts with ground or metope, described decorative layer is between described substrate layer and wearing layer, described decorative layer is melamine dipping decorative paper, described wearing layer is melamine-impregnated abrasion-proof paper, and described balance layer is melamine-impregnated balance paper.
7. the preparation method of water-proof sheet material according to claim 6, it is characterized in that: what in step 2, single spreading adopted is anhydrous type adhesive, described anhydrous type adhesive comprises curing agent and the adhesive of mass ratio 5:100, and the glue-spread of single spreading is 120-150g/m
2.
8. the preparation method of water-proof sheet material according to claim 6, it is characterized in that: described backing material plate front is bright and clean, the back side is coarse, the mutual amalgamation in the back side of upper and lower two backing material plates, Cold-press adhesion layer is evenly coated on upper and lower two back sides that backing material plate is in contact with one another, and overlay coating hot pressing overlays the front in backing material plate.
