Abstract

The invention discloses a water and oil repellent finishing agent for fabrics and a preparation method of the finishing agent. The active ingredient of the finishing agent refers to perfluoroalkyl silicone acrylate copolymer. The preparation method comprises the following steps: mixing perfluoroalkyl silicone acrylate, butyl acrylate, methyl methacrylate and hydroxyethyl methylacrylate, initiating free radical emulsion copolymerization by virtue of a water-soluble initiator under the emulsification actions of a nonionic surfactant and an anionic surfactant, thereby obtaining the emulsion type perfluoroalkyl silicone acrylate water and oil repellent finishing agent with high stability for fabrics. The finishing agent is applied for finishing cotton fabrics, and the water and oil repellent effects are obviously improved. The water and oil repellent finishing agent provided by the invention is mild in preparation conditions, simple and convenient in preparation process and suitable for industrial production.
