METHOD FOR MANUFACTURING DOUBLE BOTTOM PANEL USING RECYCLED WASTE PLASTIC
The present invention relates to a method of manufacturing a double floor panel for building by recycling a waste synthetic resin. The method of the present invention comprises: a grinding step of grinding a collected waste synthetic resin; an additive injection step of 40 to 45 parts by weight of Calpet and 15 to 20 parts by weight of glass powder per 100 parts by weight of the ground material into a ground material obtained through the grinding step; an intermediate material forming step of blending a mixture having the additive injected thereinto, and extruding the blended mixture through an extruding device to obtain a chip type intermediate material; a foaming agent injection step of adding a foaming agent to the intermediate material obtained through the intermediate material forming step such that 5 to 10 parts by weight of the foaming agent are injected into 100 parts by weight of the intermediate material to mix the foaming agent with the intermediate material; and a panel molding step of injection molding a mixture of the intermediate material and the foaming agent obtained through the foaming agent injection step using an injection mold to manufacture the double floor panel. The method according to the present invention can provide a double floor panel which has excellent load resistance, is free from contraction during using of the double floor panel, and has good flame retardancy accordingly by injecting inorganic fillers such as Calpet and glass powder into the waste synthetic resin as a raw material, blending the inorganic fillers with the waste synthetic resin to primarily heat and extrude a blended material to obtain an extrudate, injecting the foaming agent into the extrudate to blend the extrudate with the foaming agent, secondly heating and pressurizing a blended material, and injection molding the heated and pressurized material, thereby enabling the a double floor panel to have compact structure and uniform internal density.
본 발명은 폐합성수지를 재활용한 건축용 이중바닥패널 제조방법에 관한 것이다. 이는, 수거된 폐합성수지를 분쇄하는 분쇄단계와; 상기 분쇄단계를 통해 얻은 분쇄물에, 분쇄물 100중량부 당, 칼펫트 40 내지 45중량부, 유리분말 15 내지 20중량부를 투입하는 첨가제투입단계와; 상기 첨가제가 투입된 혼합물을 배합한 후, 압출장치를 통해 압출하여 칩 형태의 중간재를 얻는 중간재 형성단계와; 상기 중간재 형성단계를 통해 얻은 중간재에 발포제를 가하되, 중간재 100중량부 당, 발포제를 5 내지 10중량부 투입하여 배합하는 발포제투입단계와; 상기 발포제 투입단계를 통해 얻은 중간재와 발포제 혼합물을, 사출금형을 이용해 사출 성형하여 이중바닥패널을 제작하는 패널성형단계를 포함하는 것을 특징으로 한다. 상기와 같이 이루어지는 본 발명은, 원료인 폐합성수지에 칼펫트(CALPET)와 유리분말 등의 무기성 충진제를 투입 및 배합하여 1차로 가열 압출하고, 압출된 압출물에 발포제를 넣어 배합 후 2차 가열 및 가압하여 사출 성형하므로, 조직이 치밀하고 내부 밀도가 균일하여 그만큼 내하중성이 뛰어나며, 사용 중 수축의 염려가 없고 난연성이 좋은 이중바닥패널을 제공할 수 있게 한다.
