Referring to Figures 1 to 6, the method of manufacturing a pattern for the surface treatment of leather products according to the present invention rubber frame manufacturing step 100, and paraffin

It is composed of a frame manufacturing step 110, a gold powder coating step 120, a copper frame manufacturing step 130, and a stainless plating step 140.

The rubber frame manufacturing step 100 is applied to the surface of the pattern of the pattern plate 10 having the desired pattern to cure by applying a rubber

The rubber mold 11 is completed by releasing from the pattern plate 10 and releasing, and the finished rubber mold 11 is a flat fixing plate 1.

3) Place on the rubber frame manufacturing step 100 as described above, the paraffin frame manufacturing step 110 is performed.

The paraffin manufacturing step 110 is a mixture of paraffin and graphite powder in a ratio of 40: 60% by weight to 60: 40% by weight and heated

The liquefied paraffin-graphite mixture 14 is poured onto the pattern surface of the rubber mold 11, cooled for a predetermined time, and cured, followed by paraffin-graphite.

The paraffin mold 12 is produced by releasing the mixture 14 from the rubber mold 11. The preparation of the paraffin mold 12 is completed.

The gold foil powder coating step 120 is performed. The gold foil powder coating step 120 is a paraffin mold 12 when the copper mold 16, which is the final pattern frame, is produced.

The gold foil powder 15 is applied on the pattern surface of the paraffin mold 12 so as to float very precisely.

When the gold powder spreading step 120 is completed, the copper mold manufacturing step 130 is performed.

The copper frame manufacturing step 130 is installed in the plating cylinder 24 so that the paraffin frame 12 is coated with gold powder on the pattern surface

By depositing very fine copper particles on the pattern surface of the paraffin mold 12 coated with gold powder 15 to produce a copper mold 16

After the copper mold 16 is released from the paraffin mold 12, the final mold of the copper mold 16, which is the final pattern frame to be used for the surface treatment of leather products, is made.

The operation is completed. The copper mold production step 130 is completed as described above.

That is, the plating cylinder 24 is an open top surface of the plating cylinder 24 with a water-lactic acid mixture obtained by mixing water and lactic acid (sulfuric acid) in a 7: 3 ratio.

And maintain a temperature of 30 to 35 ℃

On the upper surface of the plating tube 24, a plurality of current bars 25 are horizontally installed, but the current bars 25 have a current of 4V.

Is energized

When installed so as to be completely submerged, a current of 4 V is supplied to the copper lumps 27 and the paraffin mold 12, and the copper tongue 27

The fine copper particles fall and move toward the paraffin mold 12 to be seated on the pattern surface of the paraffin mold 12 to which the gold powder 15 is applied.

When the copper mold 16 is gradually formed, the copper mold 16 having the required thickness is formed in about 3 to 4 days.

The stainless plating step 140 is to smooth the surface of the copper mold 16 produced in the copper mold manufacturing step 130

The copper mold 16 is provided to be energized in the plating tube, and the stainless plating 17 is applied to the surface. The surface of the copper mold 16 is as described above.

The stainless steel plate 17 is completed to complete the copper frame 16, which is a pattern frame to be used for the surface treatment of leather products.

7 to 13, the surface treatment method of the leather product according to the present invention is a paint coating step 200, synthetic resin coating step (21)

0), the first adhesive coating step 220, the second adhesive coating step 230, the natural leather attachment step 240, the drying step 250, leather

It consists of demolding step 260

The paint coating step 200 is one or more colors required for the pattern surface of the copper mold 16 completed by the manufacturing method

Paint 18 having a thickness of 20 and dries it to dry

The synthetic resin coating step 160 is a predetermined proportion of a curing agent on the dried paint 18 when the applied paint 18 is completely dried

Synthetic resin (19) with mixed polyurethane, ball-saturated polyester resin, etc. is applied, dried for a predetermined time, and cured

Form a synthetic resin layer

The primary adhesive coating step 170 is to apply the adhesive on the cured synthetic resin 19 when the synthetic resin coating step 160 is completed

After drying to form a layer of the first adhesive 20, the secondary adhesive coating step 180 is bonded again on the layer of the first adhesive 20

The agent is applied to form a layer of secondary adhesive 21.

The natural leather attaching step 190 is a natural leather (2) is larger than the pattern frame in advance when the secondary adhesive coating step 180 is completed (2)

2) is bonded onto the secondary adhesive 21

The drying step 200 is approximately 2 in a drying chamber set to a temperature of 30 to 40 ℃ when the natural leather attaching step 190 is completed

The leather demolding step 210 demolds the natural leather 22 from the copper mold 16 when the drying step 200 is completed.

When the demolded leather is attached to the synthetic resin (19) layer and the paint (18) layer sequentially, the demolded leather is formed on the surface of the natural leather (22).

You will have the pattern of the color

Natural leather with the surface treatment as described above can not only produce a variety of leather products, but also have various shapes

It is possible to insert various patterns on the surface of the leather by fixing the mold to the surface of the livestock and removing the paint in the shape of the mold.

All

Method of making a pattern for surface treatment of leather products according to the present invention having the configuration as described above and the surface treatment method using the frame is the best

The pattern frame used for the surface treatment of the leather is very cheap and simple by the pattern frame manufacturing method according to the present invention.

It can be manufactured, and because the pattern is made of copper, it can be used semi-permanently as well.

The pattern can be produced very easily, and the texture and feel of the surface-treated leather are excellent, and the pattern is made by synthetic resin.

This ensures that even if the leather is used for a long time, it will not only prevent the pattern from being disturbed, but also the surface treatment process.

It is very simple and can work with only a few people, which greatly improves productivity.

It can be greatly lowered
