Fumed silica derivative with quaternary ammonium groups was used in leather making
Abstract:Fumed silica derivative with quaternary ammonium groups(FSQA)have been prepared by the reaction of nano-fumed silica to γ-chlopropyltrimethoxysilane, then quaternization with N , N-dimethyl-n-tetradecylamine. FSQA had excellent antibacterial activity to E.coli , S.aureus and the mildew from wetblue hides. The leathers top-coated with the mixture of FSQA and the polyurethane gloss finishing agent, the polysiloxane auxiliary or the nitrocellulose finishing agent had good antibacterial activity to E.coli and S.aureus.
Keywords: leather making fumed silica quaternary ammonium salt antibacterial coating
