Abstract
A preparing process of thermoplastic polyurethane leather with figure on surface is provided. It contains steps as follow. First, dry the elastic particles of thermoplastic polyurethane leather. Second, expel elastic thermoplastic polyurethane material using extruder to parting paper with figure. Third, roll the melting material to form a film on parting paper using calendar. Forth, draw the film using drawing device from parting paper. Then the product is obtained. The progress is simple and available.
Description
Technical field
The present invention relates to the production technology of thermoplastic polyurethane leather, be meant that specifically a kind of surface has the production technology of the thermoplastic polyurethane leather of decorative pattern.
Background technology
Polyurethane Thermoplastic Elastomer is to produce the raw material commonly used of dermatine.A kind of " method for making of high-strength thermoplastic polyurethane artificial leather " disclosed for No. 98100526.8 as Chinese patent application, this method is to be extruded with extruder in 100 ℃ to 240 ℃ mixed meltings by Polyurethane Thermoplastic Elastomer resin and batch, obtain the film of thickness 0.02mm to 6.0mm through the film forming machine, fit again or coat surface temperature and remain on room temperature to a kind of base cloth of 200 ℃ of preheatings, through embossing or surface treatment and make leatheret, this base cloth is selected from by polyester again, rayon, cotton, nylon, polypropylene, wool, fiber crops, polyurethanes, polyacrylonitrile, polybutadiene, polystyrene, what polymethyl methacrylate and derivative thereof were made weaves cotton cloth or nonwoven fabric.
The production technology of common in the industry thermoplastic polyurethane artificial leather is similar to preceding method, in this method, be to obtain the dermatine that the surface has decorative pattern by the method that the dermatine with moulding carries out embossing or hot transfer printing, this embossing or hot transfer step have increased the complexity of whole technical process, equipment.
Summary of the invention
The invention provides the production technology that a kind of surface has the thermoplastic polyurethane leather of decorative pattern, its main purpose is to overcome existing technology and carries out embossing or hot transfer printing by the dermatine with moulding and obtain the dermatine that the surface has decorative pattern and cause the comparatively defective of complexity of technology.
The present invention adopts following technical scheme: the surface has the production technology of the thermoplastic polyurethane leather of decorative pattern, comprising: 1) the Polyurethane Thermoplastic Elastomer particle is dried; 2) with the melt of extruder extruded thermoplastic polyurethane elastomer, be cast on the release liners that is printed on decorative pattern in advance; 3) with calender the melt on the release liners is carried out roll-in, with the bond of release liners formation thin wall shape; 4) release liners is peeled off after with pulling equipment calender being left in the traction of this bond, made decorative pattern stay the surface of finished product leather.
Aforementioned surfaces has the production technology of the thermoplastic polyurethane leather of decorative pattern, and wherein, step 1) adopts circulating air to dry, and temperature is controlled at 80 ℃-100 ℃, and the time of oven dry is 3-4 hour.
Aforementioned surfaces has the production technology of the thermoplastic polyurethane leather of decorative pattern, wherein, step 2) the speed of a motor vehicle of extruder be 700 to change per minutes to 800 and change per minutes, the temperature of the Polyurethane Thermoplastic Elastomer melt of extruding is 180 ℃-195 ℃.
Aforementioned surfaces has the production technology of the thermoplastic polyurethane leather of decorative pattern, and wherein, the pressure of step 3) calender roll-in is 20-30 atmospheric pressure.
Aforementioned surfaces has the production technology of the thermoplastic polyurethane leather of decorative pattern, and wherein, in the step 4), pulling equipment is peeled off the traction of this bond after the foaming to 200 ℃ the baking oven again with release liners.
As from the foregoing, the present invention overcome it has been generally acknowledged that in the industry should be after the leather moulding again in the prejudice of its embossed surface or stamp, and directly the direct curtain coating of thermoplastic polyurethane melt is being had on the release liners of decorative pattern, and then release liners peeled off and make decorative pattern stay leather surface, embossing or hot transfer step have not only been reduced, thereby oversimplified whole process flow, simplified and produced used equipment, and made decorative pattern be incorporated into the surface of finished product leather more firmly.
Description of drawings
Fig. 1 is a process flow diagram of the present invention.
Specific embodiment
Below with reference to Fig. 1 specific embodiments of the invention are described.
A kind of surface has the production technology of the thermoplastic polyurethane leather of decorative pattern, its equipment that adopts comprises circulating air drying plant, heavy caliber extruder, calender, pulling equipment and winder, these equipment are prior art, be easy to buy, do not describe in detail at this from current market.
With reference to Fig. 1, this production technology comprises:
Step 1: the circulating air drying plant is with the oven dry of thermoplastic polyurethane elastomer particle, and temperature is controlled at 80 ℃-100 ℃, and the time of oven dry is 3-4 hour;
Step 2: the thermoplastic polyurethane elastomer particle of oven dry is put into the heavy caliber extruder, extruded thermoplastic polyurethane melt, the speed of a motor vehicle of extruder is that 700 commentaries on classics per minutes to 800 change per minute, the temperature of the thermoplastic polyurethane melt of extruding is 180 ℃-195 ℃;
Step 3: the thermoplastic polyurethane melt-flow is extended down on the release liners, and this release liners is printed on decorative pattern in advance, and in the present embodiment, this release liners adopts heat to tear the shape release liners, and this decorative pattern adopts printing machine to be pre-printed onto on the release liners;
Step 4: the thermoplastic polyurethane melt with on the calender roll-in release liners, make itself and release liners be combined into the bond of thin wall shape, the pressure of this roll squeezer is set at the 20-30 atmospheric pressure;
Step 5: draw to 200 ℃ baking oven by the bond of pulling equipment, again release liners is peeled off after the foaming, and made the printing ink strong bonded that constitutes decorative pattern in the surface of finished product leather with this thin wall shape;
Step 6: through after the assay was approved by winder with the rolling of finished product leather.
Above steps can adopt the automatic assembly line of being made up of each several part equipment to produce.
The pattern that the printing ink that decorative pattern among the present invention on the release liners is not limited to adopt printing machine to print forms also can be to adopt other material to engrave the decorative pattern of the sheet that forms.
Above-mentioned only is a specific embodiment of the present invention; but design concept of the present invention is not limited thereto; design of the present invention mainly is the thermoplastic polyurethane melt-flow is extended down on the release liners that is printed on decorative pattern in advance; again release liners is peeled off after the light calendering; thereby obtain the thermoplastic polyurethane leather that the surface has decorative pattern; allly utilize this design that the present invention is carried out the change of unsubstantiality, all should belong to the behavior of invading protection domain of the present invention.
