Super hydrophobic surface refers to that water static contact angle is more than 150 ° and the roll angle surface less than 10 °, have and be widely applied very much value, be mainly reflected in the aspects such as automatically cleaning, antifog, anti-adhesive anti-pollution, anti-icing, anticorrosive, oil-water separation, fluid drag-reduction, battery.
Although the preparation method about super hydrophobic surface has a lot, if Zhu etc. is at 390 DEG C, the mixture of hot pressing CNTs and PTFE when 256kPa, prepare the super-hydrophobic composite [ZhuXT that contact angle is 159 ° and roll angle is 3 °, ZhangZZ, RenGN, etal..Anovelsuperhydrophobicbulkmaterial.J.Mater.Chem., 2012, 22 (38): 20146-20148], possess good anti-wear performance and recoverability energy, ultra-hydrophobicity is still kept after sand paper is repeatedly polished, composite can make material recover ultra-hydrophobicity after being polluted by hexadecane by lighting removal hexadecane. but all there is complicated process of preparation in the existing method preparing super hydrophobic surface, cost is high, wear no resistance, poor stability, is difficult to the deficiencies such as mass production, therefore the simple and practical and applicable extensive method preparing multi-functional super-hydrophobic coat is studied, the Main way that development of new, intelligence and good mechanical stability super-hydrophobic coat will be research super hydrophobic surface.
Pass through addition; what the modes such as condensation were formed after being sulfided into solid has the organic silicon rubber body of rubber property; there is the features such as ozone aging nontoxic, high temperature resistant, resistance to, excellent electrical insulation capability, fungicidal properties and highly-breathable energy, be widely used in the aspect such as moldings, industry auxiliary products, medical sanitary product, food industry, silicon rubber protective sleeve, kitchen articles, toy, ornaments. Silicone rubber is non-petroleum product simultaneously, does not rely on petroleum resources day by day in short supply so that silicone rubber productive consumption amount is growing, has the trend substituting similar plasthetics. If waste silicone rubber therefore can be made full use of, to reducing production cost, save the energy and suffer from significance.

(3) mould is placed on compression molding instrument, more than 4MPa and polymeric matrix melt temperature when after hot pressing 10-120min, cooling, the demoulding;
(4) powder that removal step (3) gained composite coating surface is loose, obtains the super-hydrophobic wear-resisting composite coating of silicone rubber comburant polymer-matrix.
In the present invention, described silicone rubber is by addition, the organic silicon rubber body that condensation mode is formed after being sulfided into solid.
In the present invention, described being ground to by comburant Powdered can adopt mortar or grinder to grind, and flour mill, edge runner mill or ball mill pulverizing, powder beater or soy bean milk making machine beat powder.
In the present invention, described polymeric matrix can be one or more thermoplastic resins in polypropylene, polyethylene, polrvinyl chloride, Kynoar, polystyrene, Merlon, polyamide, polymethyl methacrylate, polyformaldehyde, polyester, polysulfones, polyphenylene oxide.
The present invention obtains the material of the micro-nano binary coarse structure of uniqueness after utilizing silicone rubber burning, this material itself has hydrophobicity. By hot pressing at polymer surfaces, prepare super-hydrophobic wear-resisting composite coating.
The inventive method is easy, cost is low, without complicated chemical treatment, gained composite coating hydrophobicity is good, with the static contact angle of water more than 150 °, roll angle is less than 10 °, wearability is good, and coating resistance to acids and bases is good simultaneously, and the raw silicon rubber used can pass through to reclaim waste silicone rubber goods, environmental protection, value is high.
