A a method for manufacturing oil absorbent using polyurethane sponge
The present invention relates to a method for manufacturing an oil absorbent using polyurethane sponge capable of providing excellent oil absorption and removal properties and being reusable. The method for manufacturing an oil absorbent using polyurethane sponge comprise: (a) a step of manufacturing a first mixture by stirring a solvent and graphite particles; (b) a step of modifying the polyurethane sponge by impregnating the first mixture with the polyurethane sponge and drying the same; (c) a step of manufacturing a second mixture by stirring the solvent and polydimethylsiloxane; and (d) a step of manufacturing polyurethane sponge on which graphite and the polydimethylsiloxane are coated by impregnating the modified polyurethane sponge with the second mixture and drying the same.
본 발명은 오일의 흡수 및 제거특성이 우수하고 재사용이 가능한 폴리우레탄 스폰지를 사용한 오일 흡수제의 제조방법에 관한 것으로, 더욱 상세하게는 (a) 용매 및 그래파이트 입자를 교반하여 제1혼합물을 제조하는 단계; (b) 상기 제1혼합물에 폴리우레탄 스폰지를 함침한 후 건조하여 폴리우레탄 스폰지를 개질하는 단계; (c) 용매 및 폴리디메틸실록산을 교반하여 제2혼합물을 제조하는 단계; 및 (d) 상기 제2혼합물에 상기 개질된 폴리우레탄 스폰지를 함침한 후 건조하여 그래파이트 및 폴리디메틸실록산이 코팅된 폴리우레탄 스폰지를 제조하는 단계;를 포함하는 오일 흡수제의 제조방법에 관한 것이다.
