Abstract

The invention discloses a preparation method of negative-pressure gauffered sofa furniture polyurethane synthetic leather. The preparation method specifically comprises the following steps: preparing an elongated flat hole-type wet-process bottom blank; carrying out dry-process overlaying, printing and surface treatment on the above wet-process bottom blank and then carrying out subsequent processing; successively preheating the above semi-finished product by a pre-baking oven for expanding, heating by a gold tube and gauffering at negative pressure to carry out surface stereoscopic lines processing; continuously immersing and rubbing the synthetic leather after negative-pressure gauffering. Then, average thickness of the finished product is increased by 3-5 mm. By the method, use comfortableness of the finished product is raised, and support force of the product under external force during using process is also enhanced. Therefore, durability of the product is boosted.

Description

A kind of preparation method of negative pressure embossing sofa furniture Synthetic Leather
Technical field
Patent of the present invention is related to a kind of preparation method of sofa furniture Synthetic Leather and in particular to a kind of negative pressure embossing The preparation method of sofa furniture Synthetic Leather, belongs to artificial synthetic leather technical field.
Background technology
With the continuous improvement of living standard, consumer is pursued to the stereoscopic sense of sofa furniture Synthetic Leather Meanwhile, the requirement more and more higher to the pliable and tough comfort level of sense of touch.Technical field of synthetic leather is mainly passed through hot pressing and is colded pressing two kinds at present Mode carries out three-dimensional appearance decorative pattern modification, but both the above technology is all to carry out malleation embossing using to synthetic leather surface, closes Finished leather average thickness reduces 5-10mm, and feel is stiff all than before embossing, and it is difficult to meet consumer, to sense of touch, pliable and tough comfort level is wanted Ask.
Content of the invention
The purpose of the present invention is to overcome deficiency in prior art, provides a kind of negative pressure embossing sofa furniture Synthetic Leather Preparation method, the product that the method produces average thickness after negative pressure embossing increased 3-5mm, and not only third dimension of patterns is strong, And the pliable and tough comfort level of sense of touch is high.
A kind of preparation method of negative pressure embossing sofa furniture Synthetic Leather of the present invention, comprises the following steps：
(1) elongate flattened form pass wet bottom base is prepared by wet processing using wet method material；(2) by wet bottom base according to Secondary carry out the techniques such as dry method veneer, stamp and surface treatment and carry out following process preparing semi-finished product；(3) semi-finished product are sequentially passed through Pre-baking box preheating expanding, gold tube heating and under negative pressure embossing, lines process, then carry out progressive flooding and rub stricture of vagina, that is, be obtained into Product.
The preparation method of negative pressure embossing sofa furniture Synthetic Leather described above, the described wet method material of step (1) Weight consist of：
In wet method material described above, described many NCO performed polymer uses it can as blowing promotor commonly used in the art React generation CO with the water in coagulation liquid2Thus playing foaming effect, NCO group at most foaming effect is good.
In wet method material described above, described pass adjustment auxiliary agent is modified silicon oil auxiliary agent, nonionic surfactant At least one of；Described modified silicon oil auxiliary agent is selected from SF-13 etc., and nonionic surfactant is selected from SF-7, LK-156 etc.. Described filler can be selected from conventional Calcium Carbonate, wood powder etc..
The preparation method of negative pressure embossing sofa furniture Synthetic Leather described above, pre-baking box described in step (3) Preheating expanding, baking oven length 10-50m, 110-145 DEG C of oven temperature.
The preparation method of negative pressure embossing sofa furniture Synthetic Leather described above, gold tube described in step (3) Heating, gold tube forms 4-6 root, diameter 5-10cm, heating-up temperature 180-210 DEG C.
The preparation method of negative pressure embossing sofa furniture Synthetic Leather described above, described in step (3), negative pressure is rolled Stricture of vagina, negative pressure pressure is 0.5-0.8Mpa, and synthetic leather cladding embossing roller angle is 180-210 °.
Gained wet bottom base thickness 0.80-0.95mm of the present invention；Gained blank thickness 0.85-1.1mm；Through negative pressure embossing Products obtained therefrom thickness 0.9-1.1mm afterwards；Final product thickness 0.9-1.1mm.
The present invention not only overcomes lower thickness after current technical field of synthetic leather embossing product embossing, partially hard the lacking of feel Point, also has the advantage that：
(1) conventional wet method regulation technology mesothyrid adjusts the addition of auxiliary agent, and wet half-finished product can be made to be formed uniformly Circular hole microstructure；But after the NCO performed polymer in formula, can be with coagulation liquid (DMF water during wet processing produces Solution, synthetic leather wet method general matter) in water reaction, generate CO2Gas is filled in that in microcosmic pass, (reaction mechanism sees below Formula), due to padding machine extruding and internal CO during wet half-finished product cohesion molding2Synergism, by wet half-finished product Microcosmic pass inclined flat oval shape is adjusted to by uniform circular hole, accompanying drawing 2 is shown in by microcosmic schematic diagram；
R-NCO+H2O→[R-NH-COOH]→R-NH2+CO2
(2) normally cold pressing and the malleation embossing technique productions such as hot pressing its final microcosmic pass of product due to the work of malleation With assuming inclined flat oval shape, therefore thickness can decline 5-10mm, and feel can be hardening；And the wet half-finished product warp of invention The techniques such as dry method veneer, stamp and surface treatment carry out following process, give after its certain appearance again through negative pressure embossing During process, due to the effect of vacuum suction, the offset flat shape oval structure of semi-finished product is adjusted to circle or setting type oval structure, Thus the product thickness after Negative pressure will not decline, and it is to increase 3-5mm, feel is thus more pliable and tough plentiful, but fabric width Shrinkable more than malleation technique, before negative pressure cotton ginning, therefore need to preheat expanding, such as step (3), finished product microcosmic schematic diagram is shown in Accompanying drawing 3；
(3) adjustment to pass due to negative pressure embossing, not only increases finished product in the comfort level using process, also improves Product is subject to support force during external force malleation in use, thus improve the ruggedness of product.
