Silver has a bright appearance,but it is easy to be oxidized and colored in the air for a long time,which affects the beauty.In order to improve the oxidation resistance of silver,this paper introduces a preparation method of antioxidant silver materials.The method is to achieve the purpose of anti-oxidation by covering an inorganic ceramic membrane on the surface of silver to avoid contact with external substances.The raw material of the membrane is tetraethyl orthosilicate,water,polyethylene glycol,boric acid,sodium metaaluminate,the best ratio is 92∶1000∶160∶3∶4,the best stirring time is 60 minutes.The antioxidant silver material prepared by this method is nearly 500 times stronger than that of pure silver.
