Expanded Vermiculite Board Apparatus and Method for making thereof
The present invention relates to an expanded vermiculite board, and a method and an apparatus for manufacturing the same. The method for manufacturing an expanded vermiculite board comprises: a first step of putting expanded vermiculite and thermoplastic resin in a hybrid heater having a mixer for mixing contents and a vacuum pump for exhausting gas at the ratio of 90-70:10-30%, mixing and heating expanded vermiculite and thermoplastic synthetic resin at the temperature of 100°C or higher, wherein the thermoplastic synthetic resin is heated only to such an extent that the resin is not dissolved, extracting moisture and air included in the expanded vermiculite and the synthetic resin by using the vacuum pump, and discharging an expanded vermiculite synthetic resin mixture to an outlet; a second step of introducing the expanded vermiculite synthetic resin mixture (hereinafter referred to as a ″mixture″) discharged in the first step to a screw extruder to press and heat the mixture further until the resin is dissolved and uniformly mixed with the expanded vermiculite, and extruding the mixture to a T die inlet at high pressure to discharge a flat board through a T die exit; and a third step of consecutively supplying deco sheets to overlap an upper or a lower portion of the flat board discharged through the T die exit in the second step, and introducing the flat board and the deco sheets together into an inlet hole between two conveyor belts in a conveyor compressor, so that the mixture and the deco sheets are heated and cooled in a space between the conveyor belts while moving together with the belts by the rotating conveyor belts, and thus, an expanded vermiculite board, in which the deco sheets and the mixture are completely combined together, can be extruded through an outlet hole. According to the present invention, the expanded vermiculite board can be used for various purposes such as furniture materials, building materials, flooring materials.
본 발명은 팽창질석보드, 그 제조하는 방법과 장치로서, 내용물을 혼합하는 믹서와 가스를 배기하는 진공펌프를 가진 혼합가열기에, 팽창질석과 열가소성수지를 90~70% : 10~30% 비율로 투입하고, 팽창질석과 열가소성합성수지를 혼합시키면서 100℃ 이상으로 가열하되 수지가 용해되지 않을 정도까지만 가열하면서, 진공펌프로 팽창질석과 합성수지에 포함된 수분과 공기를 뽑아낸 다음 배출구로 팽창질석합성수지혼합물을 배출하는 제1공정과; 상기 제1공정에서 배출되는 팽창질석합성수지혼합물(이하에서 "혼합물"이라고 한다)을 스크류압출기에 인입되게 하여, 가압하면서 더욱 가열하여 수지가 용융되어 팽창질석과 균일하게 혼합되도록 하며, 고압으로 T다이 입구로 압출하여 상기 혼합물이 T다이 출구에서 평판보드로 배출되게 하는 제2공정과; 상기 제2공정을 통하여 T다이에서 배출되는 평판보드 위 또는 아래에 데코시트가 겹처지도록 연속적으로 공급하여 콘베어벨트 압축기의 2개의 콘베어벨트 사이 인입구로 함께 인입되게 하고, 콘베어벨트의 회전에 의하여 벨트와 함께 이동하면서 콘베어벨트 사이에서 상기 혼합물과 데코시트가 가열 및 냉각되면서 상기 데코시트와 혼합물이 완전히 일체로 합하진 팽창질석보드로 되어 인출구에서 배출되게 하는 제3공정을 포함하는 것이 특징인 팽창질석보드 및 그 제조방법과 장치이다.
