본 발명은 핫프레스 공법에 의한 수지제품의 제조방법에 관한것으로, 더욱 상세하게는 합성수지시트인 ABS 시트와, 투명아크릴 시트 또는 옥무늬, 물결무늬등 각종 무늬가 형성된 반투명의 아크릴시트를 합지하여 특정의 수지제품을 구성하는 진공 성형금형에 이송 투입하고, 진공성형하여 완성하므로서 ABS 수지와 아크릴수지의 시트가 열강합법에 의해 합지되면서 더욱 견고해져 충격, 열손상방지 및 기스방지, 자외선에 의한 색손상 방지, 내후성등을 기해 제품의 품위를 안정시키고 사용수명을 더욱 길게 연장할수 있게 하며, 또한 ABS 시트와 아크릴 시트사이에 데코시트를 개재하여 제품의 미려함과 고급화를 기 할수 있게한 핫프레스 공법에 의한 수지 제품의 제조방법에 관한 것이다.The present invention relates to a method for manufacturing a resin product by a hot press method, and more specifically, ABS sheet, which is a synthetic resin sheet, and a transparent acrylic sheet or a translucent acrylic sheet having various patterns such as a jade pattern or a wave pattern, are laminated. The sheet of ABS resin and acrylic resin are laminated together by the heat-strengthening method to transfer them to the vacuum molding mold constituting the resin product of the resin product and to be vacuum-molded to be more rigid, preventing shock, thermal damage and gas, and color damage by ultraviolet rays. It is made by the hot press method that stabilizes the product's quality and prolongs its service life through prevention, weather resistance, etc., and also enhances the beauty and quality of the product by interposing a deco sheet between the ABS sheet and the acrylic sheet. A method for producing a resin product.

일반적으로 ABS 수지시트를 이용한 제품들은 욕조, 싱크대 상판, 세면대, 각종 기계커버, 자동차용 스페어 타이어 커버등 그 제품의 종류는 다양하고 용도에 따라 그 표면처리를 다르게 하고 있다.In general, the products using ABS resin sheets are various types of products such as bathtubs, sink tops, wash basins, various machine covers, automotive spare tire covers, and have different surface treatments according to their use.

예를 들자면, 욕조나 싱크대 상판, 집차등의 스페어 타이어 커버나, 각종 기계류의 커버등의 수지제품들은 일정두께를 갖는 ABS수지 시트를 그대로 진공 성형한후, 분체도장 또는 페인팅하여 이루고 있기 때문에 충격, 열손상등에 약하고, 표면에 기스가 나거나 작은 충격에도 쉽게 파손되는등의 문제가 있었다.For example, resin products such as the cover of a bath, a sink top plate, a spare tire cover such as a truck, a cover of various machinery, and the like are formed by vacuum-forming an ABS resin sheet having a certain thickness, followed by powder coating or painting. It was weak to thermal damage and had problems such as a scratch on the surface or breakage easily even with a small impact.

이를 개선하기 위하여 ABS 수지시트를 압출 할때 그 표면에 0.05mm 정도의 아크릴시트를 압출코팅 하는 방법이 제시되기도 하였으나, 이또한 충격 열손상등에 약한것은 상기한 문제와 동일하고, 코팅층에 의한 표면의 기스를 약간 덜 나게 하는정도의 미미한 수준에 그치고 있다.In order to improve this problem, a method of extrusion coating an acrylic sheet of about 0.05mm on the surface of the ABS resin sheet has been proposed. However, the weakness of impact thermal damage is the same as the above problem, and the surface of the coating layer It is only a minor level that makes Gis a little bit better.

또한 기존 ABS 수지시트의 상면에 PVC 필름인 테코시트를 부착하여 프레스 가공하였던 기술이 공지되어 있으나, 이는 위 ABS 수지시트의 상면에 시트지를 단순 부착하여 프레스 가공하는 형태를 취하고 있기 때문에 외관이 미려하지 못하고 표면에 이물감이 느껴지며 욕조, 세면대, 싱크대 상판등의 사용 특성상 수분에 취약하여 시트가 ABS 수지시트로 부터 탈리 또는 박리되어 사용수명이 짧아지며, 이로인한 미관을 해치게 되는 등의 문제가 있다.In addition, there is a known technique for attaching a sheet of PVC film to the upper surface of the existing ABS resin sheet and press processing, but this is a beautiful appearance because the sheet is simply pressed on the upper surface of the ABS resin sheet. There is a problem such as a feeling of foreign matter on the surface and is vulnerable to moisture due to the use characteristics of the bathtub, wash basin, sink top plate, etc., the sheet is detached or peeled from the ABS resin sheet, shortening the service life, thereby harming the aesthetics.

본 발명은 이와같은 종래 기술이 갖는 문제를 근본적으로 해소하고 이를 개선하기 위하여 연구 창출 된 것으로, 이를 제공하는 목적은 합성수지시트인 ABS 시트와, 투명아크릴 시트 또는 옥무늬, 물결무늬등 각종 무늬가 형성된 반투명의 아크릴시트를 합지하여 특정의 수지제품을 구성하는 진공 성형금형에 이송 투입하고, 진공성형하여 완성하므로서 ABS 수지와 아크릴수지의 시트가 열강합법에 의해 합지되면서 더욱 견고해져 충격, 열손상방지 및 기스방지, 자외선에 의한 색손상 방지, 내후성등을 기해 제품의 품위를 안정시키고, 사용수명을 더욱 길게 연장할수 있게 한 핫프레스 공법에 의한 수지 제품의 제조방법을 제공하려는데 있다.
The present invention has been made in order to fundamentally solve the problems of the prior art and to improve the problem, the object of providing the ABS sheet and the synthetic resin sheet, transparent acrylic sheet or jade pattern, wave pattern, etc. The translucent acrylic sheet is laminated and transported into a vacuum molding mold constituting a specific resin product, and the vacuum molding is completed, and the ABS resin and acrylic resin sheet are laminated by the thermo-strengthening method to be more rigid, thereby preventing shock and thermal damage. The present invention aims to provide a method of manufacturing a resin product by a hot press method which stabilizes the product quality and prolongs the service life by preventing gas, preventing color damage by ultraviolet rays, and weather resistance.

본 발명의 다른 목적은 ABS 시트와 아크릴 시트사이에 데코시트를 개재하여 충격, 기스방지 및 색손상방지를 기해 사용수명의 연장과 제품의 미려함 및 고급화를 기 할 수 있게한 핫프레스 공법에 의한 수지 제품의 제조방법을 제공하려는데 있다.Another object of the present invention is a resin by a hot press method, which allows the use of a deco sheet between an ABS sheet and an acrylic sheet to extend the service life, enhance the product's beauty, and enhance the product by preventing shock, gas, and color damage. It is to provide a method of manufacturing a product.

상기한 목적을 달성하기 위하여 본 발명에서는 다음과 같은 핫프레스 공법에 의한 수지 제품의 제조방법을 제시한다.In order to achieve the above object, the present invention provides a method for producing a resin product by the following hot press method.

즉 본 발명은 각각의 압출 공정에 의해 제조된 일정 면적을 갖고 최소 0.8mm 이상의 두께를 갖는 ABS 시트부재(1)와 아크릴시트부재(2)를 다수 구비하여 하부에서 부터 같은 면적을 갖는 철판(3), 골판지(4), ABS 시트(1), 아크릴시트(2), 골판지(4'), 철판(3'), 골판지(4"), ABS 시트(1), 아크릴시트(2), 골판지(4'"), 철판(3")을 순차적으로 적층시켜 적층물을 형성시키는 단계와,That is, the present invention has a plurality of ABS sheet member 1 and acrylic sheet member 2 having a predetermined area produced by each extrusion process and having a thickness of at least 0.8 mm or more and having the same area from the bottom (3) ), Corrugated cardboard (4), ABS sheet (1), acrylic sheet (2), corrugated cardboard (4 '), iron sheet (3'), corrugated cardboard (4 "), ABS sheet (1), acrylic sheet (2), corrugated cardboard (4 '"), sequentially stacking the iron plate (3") to form a laminate,

이를 이송시켜 다수의 적재칸이 각각 보일러화 되어 내부의 온수 온도가 150℃ ~ 155℃를 유지하고 있는 열강합프레스에 순차적재하여 7kw 내외의 보일러 압력과, 10wKG의 프레스 압력을 30 ~ 40분 동안 가하여 상기 ABS 시트(1)와 아크릴시트(2)를 합지시키는 합지공정과,By transporting this, a number of loading bins are each boiler-fired, and the hot water inside is sequentially placed in a thermostatic press that maintains the temperature of 150 ℃ to 155 ℃, and the boiler pressure of about 7kw and the press pressure of 10wKG for 30 to 40 minutes. Adding and laminating the ABS sheet 1 and the acrylic sheet 2;

합지된 시트부재(10)를 일반 상온에서 30분 내외의 시간동안 공냉시켜 이송시키는 이송단계와,A conveying step of air-cooling the laminated sheet member 10 at a normal room temperature for about 30 minutes and then transferring it;

상기 시트부재(10)를 180℃ ~ 230℃ 의 성형온도를 유지하고 있는 진공성형 금형에 투입하여 일정 형상을 갖는 수지 제품을 생산하는 성형공정과,A molding process of producing the resin product having a predetermined shape by inserting the sheet member 10 into a vacuum forming mold having a molding temperature of 180 ° C to 230 ° C;

성형된 반제품 상태의 테두리부를 마감처리 하는 일련의 공정이 순차적으로 이루어지는 핫프레스 공법에 의한 수지제품의 제조방법을 제공한다.Provided is a method for producing a resin product by a hot press method, which is a series of processes to finish the edge of the molded semi-finished state sequentially.

또한, 상기에서의 합지공정중 ABS 수지시트(1)와 아크릴시트(2)의 사이에는 PVC 필름인 데코시트(5)를 개재하여 이룰수 있다.In addition, the ABS resin sheet 1 and the acrylic sheet 2 may be interposed between the ABS resin sheet 1 and the acrylic sheet 2 during the lamination process.

상기에서의 합지 공정중 ABS 시트와 아크릴시트 사이에 순차적으로 적층되는 철판과 골판지는 열강합프레스의 적층판을 이루고 있는 보일러로 부터 전도되는 고온의 열이 철판을 통해 시트의 전체면에 고루 분산시키는 역할을 하게되고,During the lamination process, the iron plate and the corrugated paper which are sequentially laminated between the ABS sheet and the acrylic sheet have a role of dissipating the high temperature heat transmitted from the boiler forming the laminated sheet of the hot rolled press evenly over the entire surface of the sheet through the iron sheet. Will be

골판지는 철판으로부터 전도되는 열이 시트의 상하부에 직접 전달하지 않고 간접 전달하여 수지시트의 변형을 방지하면서 합지작용 할수 있게 하는 것이다.Corrugated cardboard is to indirectly transfer the heat transferred from the iron sheet to the upper and lower portions of the sheet so that the resin sheet can be laminated while preventing deformation.

이때 상기 열강합프레스의 보일러 온도가 155℃이상인 경우에는 과열되어 합지되는 시트가 변형되거나, 그로인한 불량이 발생될 우려가 있고, 150℃ 이하인 경우에는 합지에 소요되는 시간이 과다하게 소요되어 생산성이 저하되는 문제가 있으며, 바람직하기로는 153℃ 내외의 온도를 유지하였을 경우, 합지가 우수하게되고 생산성에도 차질이 없었다.At this time, when the boiler temperature of the hot pressing press is 155 ° C. or higher, there is a possibility that the laminated sheet is deformed due to overheating, or a defect thereof may occur, and when the temperature is 150 ° C. or lower, the time required for lamination is excessively increased, resulting in increased productivity. There is a problem of deterioration. Preferably, when the temperature is maintained at about 153 ° C., the lamination is excellent and there is no problem in productivity.

또한 진공성형기의 성형온도 역시 180℃ 이하가 되면 성형작업성이 떨어져 생산성에 문제가 되고, 230℃이상이 되면 과열되어 탄화되거나 그로인한 불량율이 발생될 우려가 있으며, 바람직하기로는 200℃ 내외의 온도를 유지하였을 경우 생산성에도 영향이 없고 불량율이 없이 순조롭게 생산 될 수 있었다.In addition, when the molding temperature of the vacuum molding machine is also 180 ° C. or less, the molding workability is poor, and if the temperature is 230 ° C. or more, there is a risk of overheating and carbonization or a defective rate thereof. Preferably, the temperature is about 200 ° C. In case of maintaining, it could be produced smoothly without any effect on productivity and without defective rate.

이러한 본 발명은 성형 금형에 따라 완성되는 제품, 즉 욕조, 세면대, 싱크대 상판 및 각종 기계용 커버나 자동차용 스페어 타이어 커버등을 제작시 합지하여 일정 형상을 유지하고 있는 성형금형에 투입, 완성하면 되므로 별도의 후처리 공정, 예를 들자면 표면에 페인팅작업이나 분체도장과 같은 작업공정이 불필요하여 작업성 및 생산성이 대폭 향상된다.The present invention is to be completed and put into a molding mold that maintains a certain shape by manufacturing a product finished according to the molding die, that is, bath, wash basin, sink top plate and various machine covers or automotive spare tire cover, etc. There is no need for a separate post-treatment process such as painting or powder coating on the surface, which greatly improves workability and productivity.

또한 이를 사용 할 경우에도 ABS 수지시트(1)의 표면에 일정 두께를 갖는 아크릴 시트(2)가 일체로 합지되어 있기 때문에 견고하고, 충격에 강하며, 열손상방지 및 기스방지를 기해 제품의 사용수명을 장구히 유지시킬수 있게 된다.In addition, even when using this, since the acrylic sheet 2 having a certain thickness is integrally laminated on the surface of the ABS resin sheet 1, it is strong, strong against impact, and prevents thermal damage and anti-gas. Long life can be maintained.

특히 ABS 시트(1)와 아크릴시트(2) 사이에 PVC 시트인 데코시트(5)를 개재하여 합지시킨 것의경우, 충격 및 열손상 방지, 기스방지, 색손상방지등의 잇점이 있는 것은 물론이고, 제품의 미려함및 고급화를 기해 소비자들로 하여금 구매의욕을 높히게 함으로서 매출 신장에도 지대한 잇점이 있다.In particular, in the case of lamination between the ABS sheet 1 and the acrylic sheet 2 via the decor sheet 5, which is a PVC sheet, there are advantages such as impact and thermal damage prevention, gas prevention and color damage prevention. In addition, there is a huge advantage in increasing sales by increasing consumers' willingness to buy through the beauty and luxury of products.

이와같은 본 발명에 의하면 압출 금형에 의해 양산된 ABS 시트와 투명아크릴 시트 또는 옥무늬, 물결무늬등의 반투명 아크릴시트를 연속 생산 공정에 따라 다량 합지하여 일정 형태를 유지하고 있는 진공성형금형에 투입, 양산 하므로서 기존 ABS 수지물 표면에 페인팅 또는 분체도장을 해야 하거나 아크릴 코팅층이 형성되어 있는 ABS 수지시트로 성형되는 것과 비교하여 생산성에 큰 변화를 주지 않고, 열강합 합지되어 견고해짐으로서 충격, 열손상방지 및 기스방지, 자외선에 의한 색손상 방지, 내후성등을 기해 제품의 품위를 안정시키고, 사용수명을 더욱 길게 연장할수 있게 되었으며, 특히 ABS 시트와 아크릴 시트사이에 데코시트를 개재하여 충격, 기스방지는 물론이고, 자외선에 의한 색손상방지를 기해 사용수명의 연장과 제품의 미려함 및 고급화를 기 할 수 있게 되는등의 여러 유용한 효과를 동시에 거둘수 있는 매우 유익한 발명임이 명백하다.According to the present invention, a large amount of ABS sheet and transparent acrylic sheet or jade pattern, wavy pattern, etc., produced by extrusion dies are laminated in a vacuum molding mold maintaining a certain shape by laminating a large amount according to a continuous production process. As it is mass-produced, painting or powder coating is required on the surface of existing ABS resin, or compared with molding of ABS resin sheet with an acrylic coating layer, it does not change the productivity much and does not change the productivity. Also, it is possible to stabilize the product's quality and to extend its service life by preventing gas damage, preventing color damage by ultraviolet rays, and weather resistance.In particular, it is possible to prevent shock and gas by interposing deco sheet between ABS sheet and acrylic sheet. Of course, by extending the service life and the beauty and quality of the product by preventing color damage caused by ultraviolet rays It is obvious that this is a very beneficial invention that can achieve several useful effects at the same time.
