초록

주석은 땜납, 주석도금강판, 청동 합금, 투명전극용 타겟 및 화학첨가제 등에 널리 사용되고 있다. 최근 자원의 희소성 및 경제성으로 인해 주석 스크랩에 대한 재활용 기술이 연구되고 있다. 본 논문에서는 주석이 함유된 공정 스크랩, 슬러지, 도금 폐액 및 합금의 재활용 기술에 대하여 1970년부터 2013년까지 공개/등록된 한국, 미국, 중국, 일본, 유럽의 특허에 대하여 조사하였다. 특허는 키워드를 사용하여 수집하였으며, 기술의 정의에 의해 필터링 하여 연도, 국가, 출원인 및 기술에 따라 분석하였다.

Tin has been widely used to solder, tin plated steel, bronze alloy, sputtering target for transparent electrode and chemical additives. It has been widely reported to the recycling technologies for tin scraps because of the scarcity and economic efficiency of the reserve. This study was analyzed by using open/registered patents KR, US, CN, JP and EP related to recycling technologies for processing scrap, sludges, waste fluid for plating process and spent alloy containing tin in between 1970 and 2013. Patents were collected using key-words searching and filtered by filtering criteria. The trends of the patents were analyzed by year, country, appliant and technology.
