Water dispersible polyurethane emulsion for coating with ultraviolet blocking effect and moth repellency

자외선 차단 및 방충 기능을 갖는 코팅용 수분산폴리우레탄 에멀젼

Abstract

본 발명은 자외선 차단 및 방충 기능을 갖는 코팅용 수분산 폴리우레탄 에멀젼에 관한 것으로, 수분산 폴리우레탄 에멀젼에 철 이온 용액 및/또는 은 이온 용액을 포함시키는 것을 특징으로 한다. 이에 따라, 본 발명의 코팅용 수분산 폴리우레탄 에멀젼은 필름 형성 후 자외선 차단 및 방충 효과를 갖는다.
PURPOSE: A water-dispersive polyurethane emulsion for coating and a method for preparing an iron ion solution and a silver ion solution used to the emulsion are provided, which emulsion has the UV blocking and insect repelling function. CONSTITUTION: The water-dispersive polyurethane emulsion comprises 100 parts by weight of a pure polyurethane emulsion; and 10-80 parts by weight of an iron ion solution. Also the water-dispersive polyurethane emulsion comprises 100 parts by weight of a pure polyurethane emulsion; 4-20 parts by weight of an iron ion solution; and 10-40 parts by weight of a silver ion solution. Preferably the concentrations of an iron ion of the iron ion solution and a silver ion of the silver ion solution are 0.1-10 wt% and 0.05-10 wt%, respectively. The iron ion solution and the silver ion solution are prepared by electrolysis.
