The high-voltage fence circuit easily forms icing and causes the electrical network normal load overweight under conditions such as sleet, low temperature, tower, broken string take place then, collapse and make the electrical network paralysis until one-piece construction.Fast, efficiently, Jing Ji solution icing problem is to demand one of great technology of capturing at present urgently.Adopt anti-icing paint can slow down or avoid icing to form by strong-hydrophobicity coating attached to conductive line surfaces.
Form Analysis on Mechanism from icing, rely on hydrophobic surface to produce effect, can become tiny ice pearl layer very soon,, can form thin layer and ice and enclose once tiny ice pearl layer isolates hydrophobic surface but carefully drip rain to postponing the big sleet circle that build-ups ice that drips.In case form thin layer ice circle, the hydrophobic surface of coating is just icing ineffective to delaying.
It is contemplated that, to have certain heat conduction function simultaneously again if hydrophobic coating has excellent hydrophobicity, carry the thermal value in the electric process to be passed to the surface in lead, not only can suppress to drip greatly the sleet circle that build-ups ice, can suppress carefully to drip simultaneously rain and form ice pearl layer, reach efficient anti-icing purpose.Develop a kind of high-molecular coating that has high hydrophobicity and heat conduction function simultaneously, be used for the surface applied of existing Aluminium Cable Steel Reinforced, can improve anti-icing effect, solve the anti-icing problem of ultra-high-tension power transmission line.
The domestic existing anti-icing paint mainly is made up of modification acrylate class, silicone based and fluoropolymer etc.As being main film forming substance with the acrylic ester emulsion, urethane, butylbenzene and organic silicon emulsion etc. have good hydrophobic nature (Zhai Guangyu, CN1664032, modified water-proof acrylic acid paint) for the coating that properties-correcting agent constitutes behind the dried coating film.By polydimethylsiloxane, a kind of paint for preventing covering ice for insulator that conductive filler material and silane coupling agent etc. constitute can significantly reduce the ice cover on the insulator and delay the formation (Jia Zhidong of icing, Liao Weiyan, Wang Liming, Guan Zhicheng, CN1995251, paint for preventing covering ice for insulator and preparation method thereof).The RTV antifouling flush paint is applied on the electrical network lead, can obtain equally the good result that obviously alleviates icing (Chen Hao, stone peace, Yang Aimin, Henan Electric Power, 2006,03, p3).Silicon sol-benzene emulsion preparation with modification has hydrophobic, the antiicing coating of certain anti-icing performance; discovery has under the laboratory condition of-20～0 ℃ and higher relative humidity and slows down the effect (Hu Xiaohua that the aluminum steel surface freezes; Wei Xiwen; Chen Bei; material protection; 2006,03, p36-38+76-77).Adopt the polymer interpenetration network structure, utilize antistatic adsorptivity and the hydrophobic nature and the organosilyl hydrophobic nature of fluorochemical, the coating of preparation can make the obvious adsorption effect that reduces the globule of coatingsurface, and good self-cleaning is arranged and reach anti-icing purpose (Luo Junhua, the beam east of a river, Li Jianjian, Zhou Tao, Shi Zhenjia, CN1077474, the antifouling flush paint of surging).
Which kind of polymeric matrix no matter above-mentioned coating adopt, and all realizes the purpose of anti-icing with the hydrophobic nature that changes coating.From the Analysis on Mechanism of icing formation, rely on hydrophobic surface to freeze effectively merely as previously mentioned, but when carefully dripping rain formation thin layer ice circle, the hydrophobic surface of coating is just icing ineffective to delaying to postponing a big sleet.Therefore, coating is hydrophobic gives coating certain thermal conductivity simultaneously improving, and utilizes the thermal value of lead inside to transfer to hydrophobic coating, helps to suppress drizzle and drips the formation ice sheet, promotes the anti-icing effect of coating.
