본 발명은 냉장고 도어용 수지강판 제조방법에 관한 것으로, 특히 냉장고 도어용 강판에 광택면을 갖는 수지물을 라미네이팅(Laminating)하여 냉장고 도어의 외관을 미려하게 한 수지강판 제조방법에 관한 것이다.BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a method for manufacturing a resin steel sheet for a refrigerator door, and more particularly, to a method for manufacturing a resin steel sheet having a beautiful appearance of a refrigerator door by laminating a resin material having a glossy surface on a steel plate for a refrigerator door.

일반적으로 냉장고 도어용 도장강판 제조방법을 제1도에 도시한 바와 같이, 기름, 먼지등의 이물질을 제거된 강판(11)의 상측부에 도장의 밀착력을 증대시키는 인산아연계 피막(12)을 형성한 후, 다시 그 상측부에 흰색 또는 녹색등의 단색상의 도료를 스프레이하여 도장층(13)을 형성하는 방법이었다.In general, as shown in FIG. 1, a method for manufacturing a coated steel sheet for a refrigerator door is formed of a zinc phosphate-based coating 12 for increasing adhesion of coating on the upper side of the steel plate 11 from which foreign substances such as oil and dust are removed. After the formation, the coating layer 13 was formed by spraying a single color paint such as white or green on the upper side again.

그러나, 이와같은 도장강판 제조방법으로 제조된 냉장고 도어는 강판(11)의 상측부에 인산아연계 피막(12)을 형성한 후, 다시 그 상측부에 흰색 또는 녹색등의 단색 도료를 스프레이를 하게되어 도장층(13)의 표면광택 및 외관이 아름답지 못할 뿐만아니라 도료의 도장작업 후 오렌지필 현상(표면이 쭈글쭈글 해지는 현상)이 발생되어 외관이 보기좋지 못한 문제점이 있었다.However, in the refrigerator door manufactured by the method of manufacturing the coated steel sheet, the zinc phosphate coating 12 is formed on the upper side of the steel plate 11 and then sprayed with a single color paint such as white or green on the upper side. Therefore, not only the surface gloss and appearance of the coating layer 13 is not beautiful, but also an orange peel phenomenon (a crushing surface) occurs after the coating work of the paint, and thus the appearance is not good.

본 발명은 이와 같은 종래의 문제점을 해소하기 위하여 창안한 것으로, 탈지된 강판에 접착제를 도포하고, 그 상측부에 필름화된 염화비닐수지를 두께로 라미네이팅하며, 다시 그 상측부에 조개껍질 분말을 옵셋인쇄한 후, 다시 필름화된 폴리에스테르 수지를 일정두께로 라미네이팅하여 제조함으로서 비교적 간단한 제조공정으로 보다 미려한 표면광택을 갖는 냉장고 도어용 수지강판을 제조할 수 있도록 한 것인바, 이를 첨부된 도면에 의하여 상세히 설명하면 다음과 같다.The present invention was devised to solve such a conventional problem, by applying an adhesive to the degreased steel sheet, laminating the film-formed vinyl chloride resin to a thickness on the upper side, and the clamshell powder on the upper side again After offset printing, the filmed polyester resin is again laminated to a predetermined thickness to prepare a resin steel sheet for a refrigerator door having a more beautiful surface gloss by a relatively simple manufacturing process. When described in detail as follows.

제2도에 도시한 바와같이, 기름, 먼지등의 이물질이 제거된 강판(1)의 상측부에 로울러를 이용하여 접착제(2)를 도포하고, 상기 접착제(2)의 상측부에 로울러를 이용하여 임의로 색상선택이 가능한 약 100μ내의 두께의 염화비닐수지(3)를 필름화시켜 라미네이팅(Laminating)한 후, 상기 염화비닐수지(3)의 상측부에 반짝거리는 효과를 부여하기 위하여 조개껍질 등의 광택분말층(4)을 10μ이하의 두께로 옵셋인쇄를 함과 아울러 다시 그 상측부에 표면광택 및 시각적인 미려함을 주기위하여 약 30μ내외로 필름화시킨 투명 폴리에스테르수지(5)를 라미네이팅하여 제조한 것이다.As shown in FIG. 2, the adhesive 2 is applied to the upper portion of the steel sheet 1 from which foreign substances such as oil and dust are removed using a roller, and the roller is used on the upper portion of the adhesive 2. After laminating by film-forming a vinyl chloride resin (3) having a thickness of about 100μ, which can be arbitrarily selected in color, the shells and the like to give a sparkling effect to the upper side of the vinyl chloride resin (3). It is manufactured by laminating the transparent polyester resin (5) filmed to about 30μ in order to offset print the gloss powder layer 4 to a thickness of 10μ or less and to give surface gloss and visual beauty on the upper side again. It is.

이와 같은 본 발명의 냉장고 도어용 수지강판 방법은 비교적 간단한 제조공정에 의하여 진주조개, 소라, 전복등의 조개껍질 특유의 빛을 발하는 광택분말층을 도포하여 종래의 도장강판을 사용한 냉장고 도어에서는 볼 수 없었던 미려한 표면광택을 얻을 수 있을 뿐만아니라, 염화비닐수지를 녹색이나 흑색등의 임의의 색상으로 선택하여 코팅함으로써 다양한 색상의 제품을 얻을 수 있는 현저한 효과가 있게 된다.Such a resin steel sheet method for a refrigerator door of the present invention can be seen in a refrigerator door using a conventional coated steel sheet by applying a glossy powder layer that emits light peculiar to a clam shell such as a pearl shell, a seashell, and abalone by a relatively simple manufacturing process. Not only the beautiful surface gloss that was not available can be obtained, and the vinyl chloride resin can be selected and coated in any color such as green or black, thereby achieving a remarkable effect of obtaining various color products.

본 발명에서는 냉장고 도어용 수지강판을 일예로 상술하였으나, 냉장고 도어이외의 다른 가전제품에 적용하여 제조할 수 있다.In the present invention, the resin steel sheet for the refrigerator door as described above as an example, it can be produced by applying to other home appliances other than the refrigerator door.
