Abstract
The invention discloses an anti-icing insulation skin and a preparation method thereof. The anti-icing insulation skin is formed by preparing nitrile rubber, silicon dioxide, a silane coupling agent, grafted type polycarboxylic acid, methyl benzene, stearic acid, an accelerant TMTD and an anti-ageing agent. Compared with the prior art, the anti-icing insulation skin disclosed by the invention is directly covered outside the cable during cable production, so that resources are saved; moreover, hydrophobicity of the cable insulation skin surface can be greatly improved, and the anti-icing cable insulation skin has pollution resistance, so that adhesive force of a power transmission cable and ice is lowered by 70%-90%. Besides, safety of the cable is ensured by the anti-icing cable insulation skin, and production cost is lowered at the same time.
Description
Technical field
The present invention relates to the security fields of field cable, particularly a kind of ice-covering-proof cable insulation skin and preparation method thereof.
Background technology
The icing of transmission route is threatening the safe operation of electric power and network of communication.In recent years numerous scholar's research the power system problem of deicing how, research is found, utilizes hydrophobic coating can prevent transmission route icing, also can prevent that transmitting line and insulator from producing pollution flashover and ice and flashing and resemble.
But this hydrophobic coating time has been grown and can come off or ftracture, and work-ing life is short, does not reach ice-covering-proof object.Therefore consideration exploitation is a kind of can ice-covering-proof cable insulation skin.
Summary of the invention
The object of the invention is to provide a kind of can be effectively ice-covering-proof and the ice-covering-proof cable insulation skin of long perfomance life and preparation method thereof.
For achieving the above object, the present invention implements according to following technical scheme:
A kind of ice-covering-proof cable insulation skin, it is prepared from by butadiene acrylonitrile rubber, silicon-dioxide, silane coupling agent, branch type polycarboxylic acid, toluene, stearic acid, Vulcanization accelerator TMTD and anti-aging agent, the mass percent of each component is: butadiene acrylonitrile rubber 45～65%, silicon-dioxide 5～15%, silane coupling agent 5～10%, branch type polycarboxylic acid 5～15%, toluene 10～15%, stearic acid 1～3%, Vulcanization accelerator TMTD 2～3%, anti-aging agent 1～2%.
As preferred version of the present invention, described silane coupling agent is one or more in vinyltriethoxysilane, aminopropyl triethoxysilane, γ-(2,3-epoxy the third oxygen) propyl trimethoxy silicane, methyl allyl acyloxypropyl trimethoxysilane or mercaptopropyl trimethoxysilane.
A preparation method for ice-covering-proof cable insulation skin, comprises the steps:
1) utilize mechanical stirring to make the branch type polycarboxylic acid of 5～15% silicon-dioxide, 5～10% silane coupling agent and 5～15% dispersed in 10～15% toluene, then, by the ultrasonic dispersion of mixed solution 2-10min, be designated as A solution;
2) after 45～65% butyronitrile rubber dropped into plasticating in Banbury mixer, park 24 hours stand-by;
3) by moulding the butyronitrile rubber perfected, drop into Banbury mixer, add respectively A solution, 1～3% stearic acid, 1～2% anti-aging agent, after banburying, park 24 hours stand-by;
4) the good sizing material of banburying is put into opening rubber mixing machine and open refining, add the TMTD of promotor 2～3%, with opening rubber mixing machine, open after refining, enter forcing machine and be extruded into adhesive tape, extrusion temperature is controlled at 65～80 ℃;
5) adhesive tape of extruding enters mould and processes the ice-covering-proof cable insulation skin that gets product.
Compared with prior art, ice-covering-proof cable insulation skin of the present invention directly wraps in the outside of cable when producing cable, saved resource, and can increase substantially the hydrophobicity of cable insulation epidermis face, and there is anti-pollution function, make the sticking power of feeder cable and ice reduce 70-90%, the present invention has guaranteed the safety of cable, has reduced production cost simultaneously.
