The utility model mould pressing emulational wood grain is strengthened wood floors to flower, be composite construction, comprise balance ply of paper, middle density or high-density fiberboard layer, wood grain ply of paper, wear-resisting ply of paper from down to up successively, it is characterized in that the plate face mould is pressed with shallow wood grain groove and overlaps corresponding fully with the woodgrained paper texture, the interval mold pressing has V-type groove or U type groove on the plate face, and wood texture groove and groove outer plate surface wood texture groove are continuous state in the groove.

The utility model mould pressing emulational wood grain to the processing technology of flowers and trees quality plate is: is slab by raw material balance paper, middle density or high density fiberboard, woodgrained paper, abrasion-proof paper according to the compound successively pressing laminate moulding of the mode of general floorings, when raw material overlay, the carved wood grain texture of steel form overlaps corresponding with the wood texture of woodgrained paper fully, the time of overlaying is 25～28 seconds, carry out slab plate face mould die mould groove when the temperature of slab remains on 120～130 ℃ again, clamp time is 12～18 seconds.This processing technology is compared with the processing technology on the similar floor of prior art, when overlaying to slab, should be consciously be consistent during with the texture mold pressing of the wood texture carved on the steel form and the woodgrained paper behind the impregnation, make the texture of steel form mold pressing corresponding, thereby make product have more the wooden sense of reality and third dimension with the texture of woodgrained paper.Keep certain temperature through the floor slab after overlaying, carry out the post forming mold pressing with mold pressing concave slot punching block pressing plate then, at slab plate face patrix die mould groove, the plate face wood texture and the inside and outside wood grain groove texture of groove that overlay the floor, back are in full accord, it is a kind of continuous uninterrupted state, the solid wood sense effect of the existing truewood line of the effect after the assembly unit has had the modelling effect of solid wood again.

Technical datas such as the temperature that the utility model three paper one material overlays, pressure are identical with general floorings.But the time that overlays shortens, and finishes initial cure with the impregnated paper glue-line and gets final product, otherwise the glue-line of impregnated paper solidifies in advance, and the flooring product quality is affected.The secondary mould pressing type groove that on slab plate face, carries out, clamp time is unsuitable long, and generally at 12-18 between second, the main purpose of post forming is that grooved is taken shape on the slab of floor, and temperature, pressure are identical with common mold pressing floor.The temperature of slab will remain on 120-130 ℃ during mold pressing type groove, should not be too low, and when temperature is crossed low secondary and heated, the sheet material internal bond strength is affected, thereby influences the inherent quality of its product.

Advantage of the present utility model:

Wood-grain-imitating is really true to life to the solid wood sense of flower laminated flooring, does not have too big difference with solid wood on vision and feel, and its main feature is:

1, the wood texture on the floor overlaps with the texture of woodgrained paper as engraving on the plate face, and fabulous true vision is arranged.

The inside and outside wood grain groove texture of the groove of 2, mold pressing type groove is uninterrupted continuously, the lines unanimity.

3, after the assembly unit, because floor surface is fluted, its modelling effect is very true to nature, obvious.
