Abstract
The invention relates to a skin sculpture process, which is characterized in that the process comprises the following steps: a corresponding punch is manufactured according to a selected pattern, a concave die is replaced by a soft polyamine lipid plate without the need for manufacturing the concave die, and the punch and the soft polyamine lipid plate are combined into a die; a PVC sheet is pasted on the back of leather; the die is put on a hydraulic press and a leather product after adhesion is placed between the punch and the soft polyamine lipid plate; the front of the leather is tightly attached to the soft polyamine lipid plate and the PVC sheet faces to the punch; hot pressing die assembly is carried out rapidly, the temperature of the hydraulic press is 80 to 90 DEG C, the pressure is 5 to 10MPa, and the die is opened 5 seconds later for cooling; a polishing machine is used for polishing: the color on the surface layer of the leather is polished, the ground color is exposed and a comparison pattern between the bottom color and the color on the surface layer is formed; the convex combination effect of the pattern and the leather can acquire the required relief pattern on the leather. Compared with the prior art, the skin sculpture process has the following advantages that: 1. as the concave die is free from manufacture but substituted for by the soft polyamine lipid plate, the manufacturing technology is reduced and production cost is reduced; 2. manufacturing temperature is reduced; as the punch can be made from non-metallic material instead of metallic material, the production cost is further reduced and the processing is easy; 3. as for the leather, double-colored or multi-colored leather is adopted and for hot pressing and polished for forming the relief pattern with rich pattern hue.
Description
(1) technical field
The present invention relates to the manufacture craft of packaging material, relate in particular to a kind of technology of on leather, producing the space pattern of similar embossment.
(2) background technology
At present, the technology of producing the space pattern of similar embossment on leather has multiple, publication number is that the patent of invention of CN 1899857A discloses a kind of leather carving process, this technology is carried out the hot pressing matched moulds again by paste composite PVC at the leather back side, make that the embossment height increases greatly on the leather, and do not produce the leather breakage, cracking, the pattern inaccuracy, bubble, problems such as obvious wrinkle are arranged, and embossment is attractive in appearance, has natural effect, but its punch-die all need be made, and makes cost cheap inadequately, in addition, the double-colored PU leather that the heatproof that this technology is selected for use is 120 ℃ also can only obtain two kinds of contrastive colours after polishing, the pattern tone is abundant inadequately.
(3) summary of the invention
The objective of the invention is to overcome the deficiencies in the prior art, the leather carving process that a kind of cost is cheaper, the pattern tone is abundant more is provided.
The technical solution adopted in the present invention is:
A kind of leather carving process is characterized in that may further comprise the steps:
Become corresponding punch by selected design producing, die need not to make and selects for use software polyamine fat plate to replace, and punch and software polyamine fat plate are combined into mould;
At the leather back side bonding on the PVC sheet material;
Described mould is placed on the hydraulic press;
Leather and fur products after bonding is placed between punch and the software polyamine fat plate, and grain side of leather is close to polyamine fat plate, and PVC sheet material face is towards punch;
The Rapid Thermal pressing film, 80～90 ℃ of hydraulic press temperature, pressure 5～10Mpa, die sinking cooling after 5-10 kind second;
Polish with polishing machine: the leather skin color of skimming, expose background color, form the contrast patterns of background color and skin color, the combined effect of the projection of this pattern and leather can obtain desired embossing pattern on cladding.
Particularly, described leather is formed by double-colored or the hot pressing of polychrome leather.If adopt monochromatic leather, then the program of polishing can be omitted.
Particularly, described punch is made by nonmetallic materials.
The present invention is owing to adopted technique scheme, and it is compared with prior art and has the following advantages: 1, die need not to make and selects for use software polyamine fat plate to replace having reduced manufacture craft, has reduced production cost; 2, make temperature and descend, punch can adopt nonmetallic materials to make and compare by the metal material making and also reduce production cost, and is easy to processing; 3, leather adopts double-colored or polychrome leather hot pressing, can form the abundant embossing pattern of pattern tone through polishing again; 4, at the leather back side bonding on the PVC sheet material carry out the hot pressing matched moulds again, make embossment height and intensity increase greatly, third dimension strengthens, and not yielding.
(4) description of drawings
Fig. 1 is the longitdinal cross-section diagram of an embodiment of the present invention.
(5) specific embodiment
Referring to Fig. 1, a kind of leather carving process is characterized in that may further comprise the steps:
Become corresponding punch by selected design producing, die need not to make and selects for use software polyamine fat plate to replace, and punch and software polyamine fat plate are combined into mould;
At leather 1 back side bonding on PVC sheet material 2;
Described mould is placed on the hydraulic press;
Leather and fur products after bonding is placed between punch and the software polyamine fat plate, and polyamine fat plate is close in leather 1 front, and 2 of PVC sheet materials are towards punch;
The Rapid Thermal pressing film, 80～90 ℃ of hydraulic press temperature, pressure 5～10Mpa, die sinking cooling after 5-10 kind second;
Polish with polishing machine: the leather skin color of skimming, expose background color, form the contrast patterns of background color and skin color, the combined effect of the projection of this pattern and leather can obtain desired embossing pattern on cladding.
Particularly, described leather is formed by double-colored or the hot pressing of polychrome leather.If adopt monochromatic leather, then the program of polishing can be omitted.
Particularly, described punch is made by nonmetallic materials.
