금속코팅된 플라스틱 사출지퍼의 제조방법{Method for producing plastic injection molded zipper with metal coating}Method for producing plastic injection zipper coated with metal {Method for producing plastic injection molded zipper with metal coating}

본 발명은 플라스틱 사출지퍼에 관한 것으로서, 보다 구체적으로는 금속코팅된 플라스틱 사출지퍼를 제조하기 위한 방법에 관한 것이다.The present invention relates to a plastic injection zipper, and more particularly to a method for manufacturing a metal-coated plastic injection zipper.

금속재 지퍼는 광택이 미려하여 이를 적용한 의류 제품의 품질을 돋보이게 하는 장점이 있으나 자체 무게가 많이 나가 이를 적용한 의류가 밑으로 처지게 하고, 또한 지퍼와 접촉하는 섬유 부분이 쉽게 마모되는 단점이 있다.Metal zipper has the advantage of highlighting the quality of the apparel product is applied to the beautiful luster, but has a disadvantage that the weight of the apparel applied to it is drooped underneath, and the fiber portion in contact with the zipper is easily worn.

따라서 의류업계에서는 재질이 가벼우면서도 미려한 금속광택을 나타낼 수 있는 지퍼에 대한 요구가 날로 증가하고 있는 추세에 있다.Therefore, in the garment industry, there is an increasing demand for zippers that can exhibit light metallic luster and beautiful metallic luster.

이러한 요구에 부응하기 위하여 플라스틱은 진공증착 등의 방법으로 금속을 코팅할 수 있기 때문에 플라스틱 사출지퍼에 금속을 코팅하는 방법을 개발하고자 하였으나, 플라스틱 사출지퍼가 아세탈과 같은 플라스틱을 용융시켜 사출하는 것에의해 지퍼 톱니가 섬유재 띠에 고정되는 방법으로 제조되는 것이기 때문에, 플라스틱 사출지퍼에 금속을 코팅하는 것이 불가능한 것으로 생각하여 왔다.In order to meet these demands, plastics can be coated with metal by vacuum evaporation. Therefore, a method of coating metals with plastic injection zippers has been developed.However, plastic injection zippers are melted and injected into plastics such as acetal. Since zipper teeth are produced in a manner that is secured to a band of fibers, it has been considered impossible to coat metals on plastic injection zippers.

따라서, 본 발명은 금속이 코팅된 플라스틱 사출지퍼를 제공하는 것을 기술적 과제로 한다.Accordingly, the present invention is to provide a plastic injection zipper coated with metal.

상기한 과제를 해결하기 위하여 본 발명자는 톱니 형성용 플라스틱에 금속을 코팅시켜도 사출하기 위해 용융시키면 금속코팅이 상실되기 때문에 섬유재 띠에 톱니가 고정되어 있는 완성된 사출지퍼에 금속을 코팅하는 방법에 대해서 연구하였으며, 그 결과 사출지퍼에 자외선 경화성 도료(이하, "UV 도료"라 약칭한다.)를 도포하고, 도포된 도료를 자외선 조사하여 경화한 후에 진공증착기에서 금속을 코팅하게 되면 UV 도료가 경화된 지퍼톱니와 톱니 고정띠가 함께 금속코팅이 되고, 이와 같이 코팅된 지퍼는 미싱에 의해 의류, 가방류 등에 쉽게 결합되어 마치 금속재 지퍼를 적용한 것과 같은 효과를 제공한다는 매우 흥미있는 사실을 알게 되어 본 발명을 완성하게 된 것이다.MEANS TO SOLVE THE PROBLEM In order to solve the said subject, about the method which coats metal on the completed injection zipper in which the tooth is fixed to the fiber band because the metal coating is lost when it melts for injection even if metal is coated in tooth forming plastic. As a result, UV curable paint (hereinafter abbreviated as "UV paint") is applied to the injection zipper, the applied paint is cured by UV irradiation, and the metal is coated in a vacuum evaporator. Zipper teeth and toothed straps are metal coated together, this coated zipper is found to be very interesting that it is easily combined with clothing, bags, etc. by sewing machine to provide the same effect as applying a metal zipper to the present invention It is complete.

도 1은 본 발명에 따르는 금속코팅된 플라스틱 사출지퍼의 제조방법을 설명하기 위한 개략적인 공정도1 is a schematic process diagram illustrating a method of manufacturing a metal-coated plastic injection zipper according to the present invention.

그러므로 본 발명에 의하면, 띠에 톱니가 고정된 플라스틱 사출지퍼에 UV도료를 도포하는 단계, UV도료가 도포된 플라스틱 사출지퍼에 자외선을 조사하여 UV도료를 경화하여 UV코팅층을 형성시키는 단계, 및 UV코팅층이 형성된 플라스틱 지퍼에 금속을 진공증착하여 금속코팅층을 형성시키는 단계를 포함하는 것을 특징으로 하는 금속코팅된 플라스틱 사출지퍼의 제조방법이 제공된다.Therefore, according to the present invention, the step of applying a UV paint to the plastic injection zipper fixed to the teeth, the UV coating is applied to the plastic injection zipper coated UV coating to cure the UV coating to form a UV coating layer, and a UV coating layer Provided is a method of manufacturing a metal-coated plastic injection zipper, comprising the step of forming a metal coating layer by vacuum depositing a metal on the formed plastic zipper.

이하, 본 발명을 보다 상세하게 설명하기로 한다.Hereinafter, the present invention will be described in more detail.

본 발명에 따르는 금속코팅된 플라스틱 사출지퍼의 제조방법은 UV도료 코팅단계, UV도료 경화단계 및 금속코팅단계로 주 구성된다.The manufacturing method of the metal-coated plastic injection zipper according to the present invention is mainly composed of a UV paint coating step, a UV paint curing step and a metal coating step.

본 발명에서, UV도료를 도포되는 플라스틱 사출지퍼는 UV도료를 도포하기 전에 유기 용제로 세정하여 플라스틱 사출지퍼에 오염되어 있는 기름때 등의 불순물을 깨끗이 제거하여 주는 것이 바람직하다. 본 발명에서 처리되는 플라스틱 사출지퍼가 오염되어 있는 경우에는 진공증착에 의해 금속을 코팅할 때 변색이 일어나거나, 오염물의 연소로 생성되는 가스에 의한 그을음이 발생할 수도 있다.In the present invention, it is preferable that the plastic injection zipper coated with the UV paint is cleaned with an organic solvent prior to applying the UV paint to remove impurities such as oil stains contaminated with the plastic injection zipper. When the plastic injection zipper treated in the present invention is contaminated, discoloration may occur when the metal is coated by vacuum deposition, or soot may be generated by the gas generated by combustion of the contaminant.

본 발명에서 적용되는 UV도료는 자외선 조사에 의해 순간적으로 건조되는 타입의 도료로서, 일반적인 기본조성은 아크릴레이트계 프리폴리머를 바인더로하고 여기에 다관능성 아크릴레이트모노머, 광중합개시제, 안료 및 기타 첨가제로 된다. 상기 프리폴리머로서는 분자량 1,000 내지 3,000 정도의 폴리에스테르아크릴레이트. 에폭시아크릴레이트, 우레탄아크릴레이트 등이 이용되고 있다.The UV paint applied in the present invention is a type of paint which is instantaneously dried by ultraviolet irradiation, and a general basic composition is an acrylate-based prepolymer as a binder, and a polyfunctional acrylate monomer, a photopolymerization initiator, a pigment, and other additives. . As said prepolymer, Polyester acrylate of the molecular weight about 1,000-3,000. Epoxy acrylate, urethane acrylate, etc. are used.

본 발명에서 UV도료는 분무 등의 방법에 의해 플라스틱 코일지퍼에 도포한 후 자외선을 조사하여 UV도료를 경화시킨다. 플라스틱 사출지퍼의 톱니가 되는 아세탈 등의 플라스틱은 진공증착하여 금속을 코팅시키게 되면 코팅밀착성이 불량하여 쉽게 벗겨지게 되나 UV도료 경화코팅층을 개재하여 금속을 코팅시키게 되면 코팅금속이 견고하게 밀착된다. 이온건이 부착된 진공증착기를 이용하면 지퍼에코팅되는 금속의 밀착성을 더욱 향상시킬 수 있게 된다.In the present invention, the UV coating is applied to the plastic coil zipper by spraying or the like and then irradiated with UV rays to cure the UV coating. Plastics such as acetal, which is a tooth of the plastic injection zipper, are easily peeled off due to poor coating adhesion when the metal is coated by vacuum deposition, but the coating metal is firmly adhered when the metal is coated through the UV coating curing coating layer. Using a vacuum evaporator with an ion gun can further improve the adhesion of the metal to the zipper.

본 발명에 의하면 띠에 톱니가 고정된 플라스틱 사출지퍼에 UV도료 도포하기 때문에 봉재가 되어야 할 섬유재 띠 부분에도 금속 코팅이 증착되지만, 섬유재 띠에 증착된 금속코팅이 띠의 봉재성능에 아무런 악영향도 미치지 않고, 오히려 섬유재 띠에 증착된 금속코팅이 지퍼의 외관을 더욱 미려하게 하는 효과를 제공한다. 그러나, 원할 경우에는 띠부분을 가려서 UV도료를 분무하여 톱니부분만을 도포하면 톱니부분만 금속이 코팅된 플라스틱 사출지퍼를 얻을 수도 있다.According to the present invention, since the coating is applied to the plastic injection zipper with the teeth fixed on the band, the metal coating is deposited on the part of the fiber band which should be the bar, but the metal coating deposited on the band does not adversely affect the bar performance of the band. Rather, the metal coating deposited on the fiber strip provides the effect of making the zipper look more beautiful. However, if desired, it is possible to obtain a plastic injection zipper in which only the tooth part is coated by applying only the tooth part by spraying UV coating by covering the band part.

본 발명에 따라 UV코팅된 플라스틱 사출지퍼 금속을 코팅하는 데에는 통상적으로 플라스틱에 금속을 진공증착하는 공지의 방법이 이용될 수 있다. 또한 진공증착되는 금속의 종류에 특별한 제한이 없고, 수요자가 원하는 바에 따라 적당한 금속을 선택할 수 있다. 바람직한 금속의 예로는 알루니늄, 크롬, 티타늄 등이 있다.In order to coat the UV-coated plastic injection zipper metal according to the present invention, a known method of vacuum depositing a metal on a plastic can be used. In addition, there is no particular limitation on the type of metal to be vacuum-deposited, and a suitable metal can be selected according to the demand of the consumer. Examples of preferred metals are aluminum, chromium, titanium and the like.

지퍼는 한쪽 면만 외부에 노출되는 것이기 때문에 상기한 공정들을 플라스틱 사출지퍼의 일면에만 적용하여도 되나, 원할 경우 양면에 도포할 수도 있음은 물론이다.Since only one side of the zipper is exposed to the outside, the above processes may be applied to only one side of the plastic injection zipper, but may be applied to both sides if desired.

이상 설명한 바와 같은 본 발명의 특징 및 기타의 장점은 후술되는 실시예로부터 보다 명백하게 될 것이다. 단, 본 발명은 하기 실시예로 제한되는 것은 아니다.Features and other advantages of the present invention as described above will become more apparent from the following examples. However, the present invention is not limited to the following examples.

[실시예 1]Example 1

아세탈 사출지퍼를 세척용 신나로 세정하여 기름때를 제거한 후 건조하였다. 이와 같이 전처리된 사출지퍼를 일면의 띠와 톱니 전체에 걸쳐 UV도료를 분무 도포하고나서 자외선을 조사하여 UV도료 코팅층이 형성된 사출지퍼를 얻었다. 다음, UV도료 코팅층이 형성된 사출지퍼를 진공증착기에 투입하여 알루미늄을 증착시켰다. 제조된 금속코팅 지퍼에 대해서 금속코팅의 밀착성, 광택 및 재봉성능을 평가하였다. 금속코팅의 밀착성은 제조된 지퍼에 지퍼머리를 부착하고 왕복운동시켜 금속코팅이 박리되는지의 여부로 평가하였다. 평가결과는 표 1에 제시된다.The acetal injection zipper was washed with a washing thinner to remove grease and dried. The pre-treated injection zipper was spray-coated with UV paint over the entire band and teeth of one surface, and then irradiated with UV light to obtain an injection zipper having a UV coating coating layer formed thereon. Next, the injection zipper, in which the UV coating layer was formed, was put into a vacuum evaporator to deposit aluminum. The adhesion, gloss and sewing performance of the metal coating were evaluated for the prepared metal coating zipper. The adhesion of the metal coating was evaluated by attaching a zipper head to the manufactured zipper and reciprocating to determine whether the metal coating was peeled off. The evaluation results are presented in Table 1.
