Detailed Description

The present invention will be described in detail with reference to specific examples. The following examples will assist those skilled in the art in further understanding the invention, but are not intended to limit the invention in any way. It should be noted that it would be obvious to those skilled in the art that various changes and modifications can be made without departing from the spirit of the invention. All falling within the scope of the present invention.

As shown in fig. 1, the tablecloth panel provided by the invention comprises a natural plant skin layer 6, a first adhesive layer 7, a white priming printing layer 8, a backing substrate layer 9, a glue layer 10, a release film layer 14, a non-woven fabric layer 11, a pattern printing layer 5, a transparent isolation layer 15, a UV glue layer 4, a UV adhesion layer, a transparent protection film layer 2, a hardening protection layer 1, a third adhesive layer 12 and an anti-slip step-stopping cushion layer 13.

The backing substrate layer 9 is a PET transparent film or a PC transparent film, the shape of the backing substrate layer 9 is rectangular, and the thickness of the backing substrate layer 9 is 0.1-2mm, preferably 0.1 mm. The natural plant cortex 6 is made of bamboo bark, white rubber, oak bark, teak bark, elm bark, silver pear bark or black walnut bark, etc., and the thickness of the natural plant cortex 6 is 0.2-0.25mm, preferably 0.2 mm.

The first adhesive layer 7 is used for fixedly adhering the natural plant skin layer 6 and the back bottom substrate layer 9, and the first adhesive layer 7 is a hot melt adhesive layer. The white undercoat printed layer 8 is directly printed or printed in a developed pattern with white ink.

The back bottom substrate is subjected to full-page rendering on the front side, so that the brightness of the natural color of the natural plant skin is further improved. If the working procedure is lacked, the surface color of the natural bamboo skin is dark, and the appearance and aesthetic feeling of the bamboo veins of the surface of the natural plant skin in the natural environment are influenced. Meanwhile, the surface of the manufactured decorative material is bright and the grains are clear.

The pattern printing layer 5 is formed by directly printing a preset picture in a computer on the ground and polished natural plant skin by adopting a UV (ultraviolet) plane printer and printing the preset picture on one side of the natural plant skin 6 departing from the background substrate layer 9. The transparent isolation layer 15 is formed by sending the natural plant cortex 6 with the pattern printing layer 5 into a UV back sealing glue spreader for gluing and then performing light curing. The UV glue layer 4 is formed by coating UV glue on one side of the natural plant skin layer 6 with the pattern printing layer 5.

Through polishing natural plant cortex 6 smooth to scribble the UV back cover glue and carry out the transparent isolation layer 15 that the UV light formed admittedly on natural plant cortex 6, can make this internal moisture of natural plant cortex can not effectual discharge, and avoided because of the unsmooth condition that leads to natural plant cortex 6 and the transparent protection film of PET easy gassing when synthesizing of natural plant cortex surface natural line takes place, can thoroughly solve the bubble problem on finished product surface, thereby the yields of product has been improved.

The processing of the antiskid substrate comprises the following steps:

s2.1, material preparation: taking out the non-woven fabric and the anti-skid step mat for later use;

s2.2, forming an anti-skid matrix: the non-woven fabric and the anti-skid step mat are bonded into a whole, and the method comprises the following steps: s2.2.1, forming a double-sided non-drying adhesive layer: firstly, coating water gel on two sides of the non-woven fabric, and then compounding release films on the two sides of the non-woven fabric to form a water gel layer 10 and a release film layer 14; s2.2.2 and combining the non-woven fabric and the non-slip step-stopping pad, removing the release film on one side of the non-woven fabric, and then adhering the non-slip step-stopping pad on the non-woven fabric on the side of the release film.

The composite processing comprises the following steps:

s3.1, pasting and compounding: firstly tearing off a release film on one side of the non-woven fabric, which is far away from the anti-skid anti-walking pad, and then bonding one side of the background substrate layer 9, which is far away from the natural plant cortex 6, with the release film;

s3.2, normal-temperature pressing: and (4) conveying the adhered and compounded noctilucent base body and antiskid base body into 50-ton flattening equipment for high-pressure normal-temperature adhesion, and finishing all the working procedures.

Modification example 1

For the tablecloth panel, the back substrate layer 9 and the white priming printing layer 8 can be replaced by a PET (polyethylene terephthalate) light scattering film, and the thickness of the PET light scattering film is 0.1-0.25 mm. Compared with the back substrate layer 9 and the white priming printing layer 8, the PET light scattering film has the advantages that the production cost can be reduced, and the production efficiency can be improved; compared with the background substrate layer 9 and the white priming printing layer 8, the PET light scattering film has the defects that the PET light scattering film covers the shading ink completely, the pattern shadow cannot be completely hidden and covered, and the covering effect is limited. In order to further improve the covering effect, a plurality of priming printing light scattering layers 9 can be printed on any side of the PET light scattering film layer, so that the effect of completely covering the shading ink is achieved.

The advantage of adopting the background substrate layer 9 and the white priming printing layer 8 lies in that the material purchase cost of the background substrate layer is low, and the thickness of the background substrate layer 9 can be selected to be 0.1mm at the same time, so that the product is thinner.

Modification 2

According to the tablecloth panel provided by the invention, the back substrate layer 9 can be removed, and the white priming printing layer 8 can be directly printed on the back of the natural plant skin. Although the expression effect is slightly inferior to the two schemes, the purposes of reducing the natural appearance lines and the beauty of the natural plant skin and improving the visual effect can be still achieved.

Modification 3

According to the tablecloth panel provided by the invention, the step S1.7 and the surface hardening treatment can be performed after the step S1.8.4, the synthetic transparent protective film layer 2 and the natural plant cortex are adjusted.

Principle of operation

Have antiskid and stop the step bed course 13, third adhesive layer 12, non-woven fabrics layer 11, leave 14 glue film layers of type rete 10, backing substrate layer 9, white backing printing layer 8, first adhesive layer 7, natural plant cortex 6, pattern printing layer 5, UV glue film 4, UV adhesion layer, the tablecloth panel of transparent protection rete 2 and sclerosis protective layer 1, print white backing printing layer 8 through the front at backing substrate layer 9, make the ornamental material surface of making out show brightly, the line is clear. And the UV rapid curing process is preferentially adopted, so that the composite stability of the natural plant cortex 6 and the background substrate layer 9 is obviously improved, the hardening liquid with the high-temperature curing characteristic is avoided, and the hardening liquid penetrates through the natural plant cortex 6 to the background substrate layer 9 to have chemical reaction due to high temperature and long curing time, so that the composite stability and the bonding strength are influenced.
