氟化碳改性超疏水材料及其制备方法

Fluorocarbon-modified super-hydrophobic material and preparation method thereof

Abstract

The invention discloses a fluorocarbon-modified super-hydrophobic material, which is prepared from silicon rubber, a vulcanizing agent, a fluorocarbon material, polypropylene and an aid serving as raw materials, wherein the static contact angles of the raw materials are respectively greater than 150 degrees, and the drift angles are respectively smaller than 10 degrees; the vulcanizing agent is one or more of TMTD (Tetramethylthiuram Disulfide), PDM (N,N'-m-Phenylenedimaleimide), t-butyl perbenzoate and tertiary capryl peroxyester; the fluorocarbon material is prepared by fluorating a carbon material; the carbon material is one or more of carbon black, active carbon, coke, a carbon nanotube and graphene; and the aid is one or more of stearic acid, magnesium stearate and zinc stearate. A preparation method of the fluorocarbon-modified super-hydrophobic material comprises the following steps of: (1) smelting a premix compound; (2) fluorating a carbon material; (3) extruding and pelletizing; (4), performing hot pressing and cold pressing; and (5) grinding and removing scraps. The super-hydrophobic material has a remarkable super-hydrophobic effect, a simple processing method and a good application prospect. Moreover, the inside and the surface of a product substrate are provided with the same component, so that a needed super-hydrophobic surface can be formed by grinding once again when the surface is damaged.
氟化碳改性超疏水材料,它是由硅橡胶、硫化剂、氟化碳材料、聚丙烯及助剂为原料制备而成、其静态接触角均大于150°,滑移角均小于10°的材料,所述硫化剂是TMTD、PDM、过苯甲酸叔丁酯、叔辛基过氧酯中的一种或几种;所述氟化碳材料由碳材料氟化制取得到,所用碳材料是炭黑、活性炭、焦炭、碳纳米管、石墨烯中的一种或几种;所述助剂是硬脂酸、硬脂酸鎂、硬脂酸锌中的一种或几种。制备方法为:①开炼预混料;②碳材料氟化;③挤出、造粒;④热压、冷压;⑤打磨,去屑。本发明的超疏水材料的超疏水效果显著,同时加工方法简单,具有很好的应用前景。而且产品基体内部和表面具有相同成分,当表面受损后,只要再次打磨,就又可以产生所需要的超疏水表面。
