Description
본 발명은 와이어 코팅용 바니쉬용제 및 이를 이용한 와이어 코팅방법에 관한 것이며, 보다 상세하게는 악취를 발생하지 않는 와이어 코팅용 바니쉬용제 및 이를 이용한 와이어 코팅방법에 관한 것이다.The present invention relates to a wire coating varnish solvent and a wire coating method using the same, and more particularly to a wire coating varnish solvent and a wire coating method using the same does not cause odor.
텔레비젼 브라운관에는 전자총에서 RBG(Red Blue Green)을 발사하면 비임이 일직선으로 집중됨으로 이와 같은 빛을 편향시키기위해서 편향요오크 코일이 사용된다. 편향요오크에는 H-코일용으로 리츠와이어(Litz Wire)가 사용된다.In television CRTs, deflected yoke coils are used to deflect such light, as the beam is focused in a straight line when RBG (Red Blue Green) is fired from the electron gun. In deflection yoke, Litz Wire is used for the H-coil.
즉, 리츠와이어는 실선의 가는 와이어를 연선기로 꼬아서 오빈에 감고 3-5롤을 권선기의 W/F에 감은 후 전류를 가하여 와이어 2차 코팅도료인 융착 바니쉬를 녹여 와이어 선간을 융착시킨 다음 W/F형상에 따른 코일을 형성함으로써 제조된다.In other words, Ritzwire twists a thin wire of a solid wire with an twisted wire and winds it in an orbin, winds 3-5 rolls in a winding machine's W / F, and applies electric current to melt the fusion varnish, a wire secondary coating paint, to weld the wires together. It is manufactured by forming a coil according to the / F shape.
편향요오크 코일은 코일 2개를 1조로 하여 H-코일을 조립하여 모니터 CDT에 장착되어 여기에 흐르는 전류에 의해 R-G-B 비임을 편향시킴으로써 해상도가 높은 컨버젼스를 나타내게 된다.The deflection yoke coils are assembled into two sets of coils, mounted on the monitor CDT, and deflected in the R-G-B beam by the current flowing therein, thereby exhibiting high resolution convergence.
이때 전류에 의해 코일에는 열이 발생하게 되고 열에 의해 2차 코팅도료의 융착 바니쉬의 잔류용제에 의해 악취가 발생하며 또한 실제품으로 사용하는 경우 열이 가하여지면 악취가 발생된다.At this time, heat is generated in the coil by the current, and odor is generated by the residual solvent of the fusion varnish of the secondary coating paint by heat, and in the case of actual use, odor is generated when heat is applied.
또한, 와이어에 쇼트를 방지하고 및 절연성을 부여하기 위한 1차 코팅 및 냄새를 방지하고 융착성 및 슬립특성을 갖는 2차 코팅을 행한다.In addition, a primary coating for preventing shorting and imparting insulation to the wire, and a second coating for preventing odor and having adhesion and slip characteristics are performed.
그러나, 상기 피복처리한 와이어는 후속처리 공정에서 전류가 가해지는 경우 바니쉬 용제(고비점용제)에 기인한 악취가 발생한다.However, the coated wire generates odor due to varnish solvent (high boiling point solvent) when a current is applied in a subsequent treatment step.
종래의 악취방지법으로는 코일제조시 코팅 횟수 및 온도를 조절하는 방법이 행하여져 왔으나 여전히 심한 악취를 발생하는 것이다.Conventional malodor prevention method has been performed to control the number of coatings and the temperature during the manufacture of coils, but it still generates severe odor.
이에 본 발명의 목적은 냄새발생이 감소되는 와이어 코팅용 융착 바니쉬용제를 제공하는 것이다.Accordingly, an object of the present invention is to provide a fusion varnish solvent for wire coating in which odor is reduced.
본 발명의 다른 목적은 본 발명의 와이어 코팅용 융착 바니쉬 용제를 이용한 와이어 코팅방법을 제공하는 것이다.Another object of the present invention is to provide a wire coating method using a fusion varnish solvent for wire coating of the present invention.
본 발명의 일견지에 의하면,According to one aspect of the invention,
2차 동선 와이어 융착 바니쉬용제에 있어서,In the secondary copper wire fusion varnish solvent,
크레졸 20±3중량%, 페놀30±3중량% 및 크실렌 50±3중량%로된 융착 바니쉬용제가 제공된다.A fusion varnish solvent of 20 ± 3 wt% cresol, 30 ± 3 wt% phenol and 50 ± 3 wt% xylene is provided.
본 발명의 다른 견지에 의하면,According to another aspect of the present invention,
와이어를 2차 코팅처리함에 있어서,In the secondary coating of the wire,
동선 코팅 유입구의 온도를 330±10℃ 그리고 배출구의 온도를 360±10℃로 하고 융착 바니쉬 용제로서 본 발명의 용제를 이용한 동선 와이어 코팅방법이 제공된다.A copper wire coating method using a solvent of the present invention as a fusion varnish solvent with a temperature of a copper coating inlet of 330 ± 10 ° C. and an outlet of 360 ° ± 10 ° C. is provided.
이하, 본 발명에 대하여 상세히 설명한다.EMBODIMENT OF THE INVENTION Hereinafter, this invention is demonstrated in detail.
본 발명은 편향요오크 H-코일 리츠 와이어에서 발생하는 악취를 제거하고자 연구를 계속한 결과 와이어 제조시 사용되는 2차 바니쉬용제중의 성분을 제어함으로써 냄새발생이 감소됨에 착안한 것이다.The present invention focuses on the reduction of the odor by controlling the components in the secondary varnish solvent used in wire production as a result of continuing the study to remove the odor generated in the deflection yoke H-coilitz wire.
또한, 성분이 특히 제어된 바니쉬용제를 특정한 코팅온도로 동선 와이어에 코팅함으로써 냄새발생을 더욱 감소시킬 수 있다.In addition, odor generation can be further reduced by coating the copper wire at a specific coating temperature with a component controlled varnish solvent.
종래 동선와이어의 절연성을 개선하기 위해 1차로 폴리이미드수지로 코팅한 후 2차로 냄새, 융착성 및 슬립성을 개선하기 위해 2차로 폴리아마이드수지로 코팅한다. 이 때 2차 폴리아마이드수지 바니쉬 용제는 하기 표 1에 나타낸바와 같은 성분으로 구성된다.In order to improve the insulation of the conventional copper wire, it is first coated with polyimide resin and then secondly coated with polyamide resin to improve odor, adhesion and slip. At this time, the secondary polyamide resin varnish solvent is composed of the components as shown in Table 1 below.
상기 표 1에 나타낸 수집된 면적의 총합은 GC Mass 가스발생량의 총면적을 나타낸 것이로, 상기 수치는 악취발생량을 나타낸다.The total of the collected areas shown in Table 1 represents the total area of the GC Mass gas generation amount, the value represents the odor generation amount.
상기 표 1에서 알 수 있듯이 종래 사용되는 2차 바니쉬코팅용 용제는 고비점성분이 높은 비율로 함유되어 있으며 이와 같이 고비점성분이 다량함유되어 있는 경우, 고비점용제성분은 휘발하지 않고 후속공정까지 잔류하게되어 후속공정 및/또는 최종 제품의 실사용시 악취를 발생하게 된다.As can be seen from Table 1, the secondary varnish coating solvent conventionally used has a high ratio of high boiling point components, and when such high boiling point components are contained in a large amount, the high boiling point solvent component does not volatilize until the subsequent process. It will remain and cause odors in the subsequent use of the process and / or the final product.
따라서, 본 발명에서는 2차 동선 와이어 코팅용 융착 바니쉬 용제중 고비점성분의 양은 감소시키고 저비점성분의 비를 상대적으로 증가시킴으로써 공정도중 용제가 충분히 휘발되고 따라서 잔류 용제에 기인한 악취발생을 방지된다.Therefore, in the present invention, the amount of the high boiling point component in the fusion varnish solvent for secondary copper wire coating is reduced and the ratio of the low boiling point component is relatively increased, so that the solvent is sufficiently volatilized during the process and thus odor generation due to the residual solvent is prevented.
즉, 본 발명에 의한 2차 동선 와이어 코팅용 바니쉬용제는 크레졸 20±3중량%, 페놀 30±3중량% 및 크실렌 50±3중량%로 구성된다.That is, the varnish solvent for secondary copper wire coating according to the present invention is composed of 20 ± 3% by weight of cresol, 30 ± 3% by weight of phenol and 50 ± 3% by weight of xylene.
크레졸의 비점이 203℃로 고비점성분이고 페놀 및 크실렌은 비점이 각각 180℃ 및 144℃로서 저비점성분으로 본 발명에서는 종래의 용제성분에 비하여 상대적으로 크실렌의 함량이 증대된다. 이때 크레졸, 페놀 및 크실렌을 상기 비율로 혼합하여 동선 와이어 2차 폴리아마이드 용제로 사용함으로써 악취발생이 방지된다.Cresol has a boiling point of 203 ° C., a high boiling point component, and phenol and xylene have a boiling point of 180 ° C. and 144 ° C., respectively. At this time, cresol, phenol and xylene are mixed in the above ratio and used as a copper wire secondary polyamide solvent to prevent odor generation.
이와 같이 저비점성분의 함량을 증가시킴으로써 잔류하는 용제가 감소되며 따라서 후속공정에서 냄새 발생이 현저하게 감소된다.In this way, by increasing the content of the low boiling point component, the remaining solvent is reduced, and thus the generation of odor in the subsequent process is significantly reduced.
상기 본 발명의 2차 동선 와이어 코팅용 바니쉬 용제는 기타 일반적으로 바니쉬용제 제조에 일반적으로 사용되는 성분을 본 발명에서 의도하는 용제의 물성을 손상하지 않는한 포함할 수 있다.The varnish solvent for secondary copper wire coating of the present invention may include other components generally used in the production of varnish solvent as long as the physical properties of the solvent intended in the present invention are not impaired.
용제 각 성분의 양을 상기한 바와 같이 조절함과 동시에 또한 동선 와이어에 바니쉬용제를 적용하는 코팅온도를 조절함으로써 냄새의 발생을 더욱 감소시킬 수 있다.By controlling the amount of each component of the solvent as described above, and also by controlling the coating temperature of applying the varnish solvent to the copper wire, it is possible to further reduce the occurrence of odor.
즉, 본 발명의 바니쉬 용제로 처리하는 경우 동선 와이어 코팅유입구의 온도는 330±10℃ 그리고 배출구의 온도는 360±10℃로 조절한다. 즉, 통상의 동선 와이어 코팅온도보다 높은 온도에서 2차 바니쉬 용제를 코팅함으로써 코팅시 잔류하는 용제성분의 양이 감소되며, 따라서 후속공정 및/또는 최종제품사용시 전류인가에 따른 악취발생을 방지하게 된다.That is, when treated with the varnish solvent of the present invention, the temperature of the copper wire coating inlet is adjusted to 330 ± 10 ℃ and the temperature of the outlet is 360 ± 10 ℃. That is, by coating the secondary varnish solvent at a temperature higher than the normal copper wire coating temperature, the amount of solvent component remaining in the coating is reduced, thus preventing the occurrence of odor due to the application of current during the subsequent process and / or final product use. .
나아가, 코팅횟수를 증가시킴으로써 또한 악취를 예방할 수 있다.Furthermore, increasing the number of coatings can also prevent odors.
이하, 실시예를 통하여 본 발명에 대하여 상세히 설명한다.Hereinafter, the present invention will be described in detail through examples.
실시예Example
동선와이어에 폴리이미드를 1차 코팅한후, 폴리아마이드를 2차 코팅하였다.Polyimide was first coated on the copper wire, followed by second coating of polyamide.
동선 와이어를 코팅함에 있어서, 2차 코팅 바니쉬 용제의 성분 및 코팅온도를 후술한 바와 같이 조절한 것으로 제외하고는 통상의 방법으로 동선와이어를 코팅하였다.In coating the copper wire, the copper wire was coated in a conventional manner except that the components and the coating temperature of the secondary coating varnish solvent were adjusted as described below.
본 실시예에서는 GC 및 IR챠트를 이용하여 용제내에 함유되어 있는 각 성분 및 그 양을 분석하여 크레졸, 페놀 및 크실렌성분을 각각 20중량%, 30중량% 및 50중량%로된 2차 와이어 코팅용 융착 바니쉬 용제를 제조하였다.In this embodiment, each component and its amount contained in the solvent are analyzed using GC and IR charts, and the second wire coating is made of 20 wt%, 30 wt%, and 50 wt% of cresol, phenol, and xylene, respectively. A fusion varnish solvent was prepared.
이와 같이 용제의 성분을 조절한 후 이를 동선에 코팅하였다. 코팅시 동선 와이어 코팅 유입구의 온도는 330℃로 그리고 배출구의 온도는 360℃로하여 코팅하였다.Thus, after adjusting the solvent component it was coated on the copper wire. During the coating, the copper wire coating inlet was coated at a temperature of 330 ° C. and an outlet at 360 ° C.
상기한 바와 같이 동선에 바니쉬 용제를 코팅한 후 이를 사용하여 50-55Å의 전류를 0.3-0.1초동안 가하여 권선하는 경우에 발생하는 냄새를 후각적으로 확인하였으나 악취를 느낄수 없었다.As described above, after coating the varnish solvent on the copper wire, the smell generated when the winding was applied by applying a current of 50-55 0.3 for 0.3-0.1 seconds was sensed by smell, but no odor was felt.
또한, GC분석에 의한 가스발생량의 총면적의 합을 측정하였으며, 그 면적은 0.3 x 109으로 상기 통상 사용되는 바니쉬 코팅용제의 GC분석시의 가스발생 총면적의 합 1.9x109, 1.4x109보다 현저하게 감소하였으며, 이는 본 발명의 조성으로된 바니쉬 용제를 사용함으로써 냄새가 거의 발생되지 않음을 나타낸다.In addition, the sum of the total area of the gas generation by the GC analysis was measured, the area is 0.3 x 10 9 , the sum of the total area of gas generation during the GC analysis of the varnish coating solvent commonly used above 1.9x10 9 , 1.4x10 9 It was reduced, indicating that almost no odor was generated by using the varnish solvent of the composition of the present invention.
본 발명의 바니쉬 용제를 사용함으로써 바니쉬 용제 코팅된 와이어를 사용하는 경우의 냄새발생량이 감소한다.By using the varnish solvent of the present invention, the amount of odor generated when using the varnish solvent coated wire is reduced.
