상기 코팅층(3)은 성형물의 표면을 보호하고 미관을 아름답게 유지하여 상품 가치를 고급화시킬 뿐만 아니라 성형물의 광택, 수명, 내구성을 향상시키는 역할을 한다.The coating layer (3) serves to protect the surface of the molding and to maintain a beautiful appearance to enhance the product value as well as to enhance the gloss, life and durability of the molding.
이하, 본 발명에 따른 발포수지가 내장된 FRP 샌드위치 판넬의 제작 과정을 설명하면 다음과 같다.Hereinafter, the manufacturing process of the foamed resin-embedded FRP sandwich panel according to the present invention.
먼저, 발포수지가 내장된 FRP 샌드위치 판넬의 제작을 용이하게 하고 대량으로 생산할 수 있도록 별도의 밀폐 시설을 마련한다. 밀폐 시설로는, 다수개의 성형물을 적층할 수 있도록 바닥에 놓여지는 판재와, 판재의 상부에 성형물을 적층한 후 외부 공기가 유입되지 않고 진공 상태에서 압축할 수 있도록 판재의 둘레에 밀봉시키는 비닐을 이용하는 것이 바람직하다. 그리고 비닐을 밀봉하더라도 비닐 내부에 남아있는 공기를 외부로 배출하도록 진공기를 연결 설치한다.First, a separate sealed facility is prepared to facilitate the production of the FRP sandwich panel with foamed resin and to produce in large quantities. The sealing facility includes a plate placed on the floor to stack a plurality of moldings, and a vinyl sealing the circumference of the board to compress the vacuum in a vacuum without the inflow of outside air after stacking the moldings on top of the sheet. It is preferable to use. And even if the plastic is sealed, a vacuum is installed to discharge the air remaining inside the vinyl to the outside.
상기와 같이 밀폐 시설의 준비가 완료되면, 성형물을 성형하기 위하여 판재 위에 아연 도금된 강판 재질의 몰드를 위치시킨다. 먼저 하판 몰드를 판재 위에 올려놓고 하판 몰드의 상부에 원재료 상태의 유리섬유와 열경화성 수지를 함침시켜 도포한 후 그 위에 발포수지(1)를 올려놓는다.When the preparation of the closed facility is completed as described above, the mold of the galvanized steel sheet material is placed on the plate to form the molding. First, the lower mold is placed on a plate, and then impregnated and coated with glass fibers and a thermosetting resin in a raw material state on top of the lower mold, and then the foamed resin 1 is placed thereon.
그리고 상기 발포수지(1)의 상부에 유리섬유와 열경화성 수지를 함침시켜 도포한 후 상판 몰드를 덮음으로써 성형물 준비가 완료되는 것이다. And the impregnated with the glass fiber and the thermosetting resin on the upper portion of the foamed resin (1) and then covered by the top plate mold is ready for molding.
상기와 같은 과정을 수행하여 성형된 성형물을 다수개로 적층한 다음 테이프 등을 이용하여 판재의 둘레이 비닐을 밀봉시킨다. 그리고 비닐 내부를 진공 상태로 만들기 위해 진공기를 작동시켜 내부 공기를 외부로 배출시킨다. 따라서 비닐의 내부는 물론 상,하판 몰드 사이의 공기까지 외부로 배출시킴으로써 진공 상태에서 발포수지(1)의 외부에 유리섬유와 열경화성 수지의 함침물이 완전히 압축되어 흡착된다.The process as described above is laminated to a plurality of shaped moldings, and then the periphery of the plate to seal the vinyl using a tape or the like. In order to vacuum the inside of the vinyl, a vacuum is operated to exhaust the internal air to the outside. Therefore, by impregnating the inside of the plastic as well as the air between the upper and lower molds to the outside, the impregnated glass fiber and the thermosetting resin is completely compressed and adsorbed to the outside of the foamed resin 1 in a vacuum state.
마지막으로, 진공 상태에서 성형물을 자연 경화하거나 경화실을 이용하여 발포수지가 내장된 FRP 샌드위치 판넬을 완성하게 되는 것이다.Finally, the molding is spontaneously cured under vacuum or a curing chamber is used to complete the FRP sandwich panel with foamed resin.
상술한 바와 같이, 본 발명에 따른 발포수지가 내장된 FRP 샌드위치 판넬은 원재료의 유리섬유와 열경화성 수지를 함침시켜 발포수지의 외부에 도포하고 이를 진공 상태에서 압축 성형함으로써 내구성이 우수한 효과가 있다.As described above, the FRP sandwich panel with the foamed resin according to the present invention is impregnated with the glass fiber and the thermosetting resin of the raw material is applied to the outside of the foamed resin and it is excellent in durability by compression molding in a vacuum state.
또한, 내심재로 발포수지가 사용됨으로써 보온 및 단열이 우수한 효과가 있다.In addition, since the foamed resin is used as the inner core material, the thermal insulation and heat insulation are excellent.
또한, 진공 상태에서 다수개의 성형물을 적층시켜 압축 성형함으로써 판넬을 대량으로 생산할 수 있는 효과가 있다.In addition, by stacking a plurality of moldings in a vacuum state, there is an effect that can be mass-produced panel.
본 발명은 첨부된 도면을 참조하여 바람직한 실시예를 중심으로 기술되었지만 당업자라면 이러한 기재로부터 본 발명의 범주를 벗어남이 없이 많은 다양한 자명한 변형이 가능하다는 것은 명백하다. 따라서 본 발명의 범주는 이러한 많은 변형의 예들을 포함하도록 기술된 청구범위에 의해서 해석되어져야 한다.While the present invention has been described with reference to the accompanying drawings, it will be apparent to those skilled in the art that many various obvious modifications are possible without departing from the scope of the invention from this description. Therefore, the scope of the invention should be construed by the claims described to include examples of many such variations.
