Abstract
Description
제1도는 본 발명의 생지의 적층 상태도.1 is a lamination state diagram of the dough of the present invention.
제2도는 발포된 상태에서 힐스카이빙하는 상태도이다.2 is a state diagram of hill-sky in the foamed state.
본 발명은 신발밑창을 제조함에 있어서 미드솔과 장식선부 및 아웃솔을 생지상태에 적층하여 이들을 동시에 발포시킴으로써 각층간이 일체로 접착이 되도록 한 것이다.In the present invention, in manufacturing a shoe sole, the midsole, the decorative line and the outsole are laminated in a dough state to foam them at the same time so that each layer is integrally bonded.
종래의 신발에서 죠킹화나 레져용화 등의 신발밑창은 스폰지와 고무창 및 스폰지와 스폰지창 등이 접착되어 사용되었는데 그 이유는 가볍고 탄력성이 좋으며, 또한 신발에 패션화가 이루어지기 때문이었다.In conventional shoes, shoe soles such as jogging shoes and leisure shoes are used by bonding sponges and rubber soles, sponges and sponge soles, etc., because they are light and resilient, and shoes are fashioned.
그러나 이러한 신발의 밑창은 제조과정에서 스폰지와 고무창 또는 스폰지와 스폰지창을 접착함으로써 제조과정이 복잡할 뿐만 아니라 접착시 미접착으로 인하여 불량품이 발생할 뿐만 아니라 사용 중에 접착부가 떨어지는 결점이 있었다.However, the sole of such a shoe is not only complicated manufacturing process by adhering a sponge and a rubber window or a sponge and a sponge window in the manufacturing process, but also a defect due to non-adhesion at the time of adhesion, as well as a defect that the adhesive part falls during use.
본 발명은 이러한 점을 감안하여 발명한 것으로서 미드솔과 장식선부의 스폰지 생지와 고무 또는 스폰지로 된 밑창의 생지를 순서대로 적층한 다음 이들을 발포시키면 이들이 발포됨에 따라 동시에 접착이 되어 일체가 되는 것으로서 종래와 같이 접착제에 의하여 미드솔과 장식선부 및 밑창을 접착하는 과정이 축소되므로 인하여 많은 작업공정을 단축시킬 수 있고, 또한 접착불량에 의한 불량품의 발생을 제거할 수 있게 한 것이다.The present invention has been invented in view of this point, and laminating the sponge dough of the midsole and the decorative line and the dough of the sole made of rubber or sponge, and then foaming them are simultaneously bonded together as they are foamed, thereby being integrated. Likewise, the process of adhering the midsole to the decorative line and the sole by the adhesive is reduced, thereby reducing a lot of work processes, and also eliminating the occurrence of defective products due to poor adhesion.
이와 같은 본 발명을 실시예에 의하여 설명하면 다음과 같다.Referring to the present invention as described above as follows.
본 발명에서는 미드솔(1)과 아웃솔(3)부분이 각기 가지는 고유의 물성과 특성을 살리기 위하여 원료의 배합은 아래표와 같은 바 아웃솔(3)의 경우에는 흑색계통과 백색계통을 다르게 하고 있다.In the present invention, in order to make use of the inherent physical properties and properties of the
이와같이 배합에 의하여 얻어진 미드솔(1)의 경도는 51±4로서 비중, 신장율, 접착강도등 일반물성이 뛰어나며, 아웃솔(3)의 경도는 65±3으로서 비중, 인장강도, 마모등 전반적인 물성의 뛰어남과 브로모부틸고무의 장점인 충격흡수의 효과가 있으므로 신발창 부분으로서의 성능의 아래 표와 같이 종래것에 비하여 매우 우수함을 알 수 있다.Thus, the hardness of the midsole (1) obtained by blending is 51 ± 4, which is excellent in general properties such as specific gravity, elongation rate, and adhesive strength. The hardness of outsole (3) is 65 ± 3, which is excellent in overall physical properties such as specific gravity, tensile strength, and wear. Since it has the effect of shock absorption, which is an advantage of bromobutyl rubber, it can be seen that the performance of the sole part is very superior to the conventional one as shown in the following table.
(시험방법은 KSM 6518,6624에 의한 것임)(Test method is according to KSM 6518,6624)
이상과 같이 배합된 원료를 혼합기에 넣어 70－100℃에서 10분간 혼련하여 생지를 만든 다음 생지를 롤에 감아 가교제 및 발포제를 투입하면서 판으로 만든다.The raw materials blended as described above are put into a mixer and kneaded at 70-100 ° C. for 10 minutes to make dough, and the dough is rolled on a roll to make a plate while adding a crosslinking agent and a blowing agent.
이와 같이 얻어진 생지는 6시간 동안 상온에서 숙성시킨 다음 재혼련한 다음 생지의 면이 고르게 될때까지를 작업을 한 후 카렌더에 의하여 생지를 만들어 적당한 규격으로 절단한다.The dough thus obtained is aged at room temperature for 6 hours, then re-kneaded and worked until the surface of the dough is even, and then the dough is made by a calender and cut into appropriate standards.
이와 같은 방법에 의하여 얻어진 미드솔(1)과 아웃솔(3)을 적층함에 있어서 밑에는 아웃솔(3) 생지를 놓고 그 위에 미드솔(1) 생지를 포개놓은 다음 그 위에 다시 아웃솔(3) 생지를 포갠것을 프레스의 몰드에 옮겨 35분 동안 가황시킨다.In laminating the midsole (1) and the outsole (3) obtained by the above method, the outsole (3) dough is placed on the bottom, and the midsole (1) dough is piled thereon, and then the outsole (3) dough is piled again thereon. Transfer to mold of press and vulcanize for 35 minutes.
그리고 미드솔(1)과 아웃솔(3)의 사이에는 장식선부(2)을 형성하기 위하여 미드솔(1)과 아웃솔(3)의 사이에 유색의 장식선부(2)를 형성하는 생지를 가황처리를 하는 경우도 있다.And to vulcanize the dough forming a colored
가황작업이 끝남과 동시에 발포되어 각층이 접착되어 일체로 되어진 상태가 된 것을 냉각대에 옮겨 24시간동안 충분히 냉각시켜 절단기에 신발규격에 맞게 절단한 다음 제2도와 같이 힐스카이빙(4)을 하여 그라인더에 의하여 앞부분과 옆부분을 버핑하여 신발밑창을 제조하는 것이다.As soon as the vulcanization is finished, the foamed foams are bonded to each other to form an integrated state.Then, move to the cooling table and cool them sufficiently for 24 hours, cut them according to the shoe specifications on the cutter, and then heel scuba (4) as shown in FIG. The sole and side parts are buffed by the grinder to manufacture the shoe sole.
이와같은 본 발명은 종래의 방법에 비하여 작업공정이 훨씬 단축되는 것으로서 종래의 공정도와 비교하면 다음과 같다.The present invention as described above is much shorter work process compared to the conventional method as follows.
본 발명의 제조공정 :Manufacturing process of the present invention:
종래의 제조공정Conventional manufacturing process
이상과 같이 본 원발명과 종래의 제조방법을 대비한 바에 의하면 본원 발명은 종래의 제조방법에 비하여 공정이 훨씬 단축되고 또한 제조된 신발밑창을 보면 종래와 같이 접착불량에 의한 불량품이 발생하는 것을 방지할 수 있는 유용한 발명이다.As compared with the present invention and the conventional manufacturing method as described above, the present invention is much shorter process compared to the conventional manufacturing method and also to prevent the occurrence of defective products due to poor adhesion as in the conventional shoe soles produced It is a useful invention that can be done.
