METHOD FOR SUFACE MODIFICATION OF OXIDE POWDER
The present invention relates to: a method for surface modification of an oxide used in a composite material; an oxide surface modified thereby; and the composite material containing the same. According to one embodiment, the method for surface modification of an oxide may comprise the steps of: preparing an oxide obtained from an industrial by-product; and stirring the oxide with a sulfurizing agent. According to the present invention, it is possible to facilitate the supply and demand of raw materials by utilizing steel slag, desulfurized gypsum, and other industrial by-products that have similar properties to inorganic fillers using calcium carbonate and talc that were used conventionally, and a composite material that is more price competitive than existing silane treatments can be produced by means of surface modification through a sulfurization process. The surface-modified oxide through the sulfurization treatment can be used as a composite material by compounding the same with waste plastic.
본 발명은 복합소재에 활용되는 산화물의 표면개질 방법, 이에 따라 표면개질된 산화물 및 이를 포함하는 복합재료에 관한 것이다. 일 실시예에 따른 산화물의 표면개질 방법은 산업부산물에서 수득한 산화물을 준비하는 단계; 및 상기 산화물과 황화제를 교반하는 단계를 포함할 수 있다. 본 발명에 따르면, 종래에 사용되던 탄산칼슘과 활석을 이용한 무기필러와 특성이 유사한 철강슬래그, 탈황석고, 그 외의 산업부산물을 활용하여 원재료 수급을 용이하게 하고, 황화처리 공정을 통해 표면개질함으로써 기존 실란처리보다 가격경쟁력이 우수한 복합소재를 제조할 수 있다. 황화처리로 표면개질된 산화물은 폐플라스틱과 컴파운딩하여 복합소재로 활용할 수 있다.
