Abstract
The present invention provides a kind of room temperature silicon sulfide rubber composite nano material pollution flashover resisting coating capable of raising pollution flashover voltage function. Its raw material composition includes 3%-10% of dihydroxypolymethylvinylsiloxane and 12%-20% of dihydroxypolydimethylsiloxane as main material, 0.3%-10% of nano silicon dioxide and 0.3%-10% of nano titanium dioxide as filling material and 50%-65% of diluting agent. Said coating can be used as coating material for coating or brushing surface of insulating body of high-voltage power equipment.
Description
Technical field
The present invention relates to field of paint, in particular, relate to a kind of room temperature silicon sulfide rubber composite nano-material antifouling flush paint that is applied to power transmission and transformation equipment outer insulation position surface daub on a wall.
Background technology
Present existing silicon rubber antifouling flush paint exists certain deficiency in application process.Be embodied in the coating after the sulfuration, surface hydrophobicity forfeiture phenomenon can occur behind water logging bubble certain hour, coatingsurface can form the successional moisture film of big area even even worse.Though existing DL/T627-2004 standard code " water logging bubble 96 hours; Recovered 24 hours, hydrophobic nature is not less than the HC2 level " just can be judged to be qualified, but we think the important application characteristic of existing this kind product be have circumscribed.Owing to have capillary effect after the room temperature vulcanized silicone rubber sulfuration, the saturating wet speed of silicon rubber is very fast, and moisture content is easily invaded rubber bodies inside, therefore causes water resistance relatively poor.
Summary of the invention
Technical problem to be solved by this invention is, overcomes the deficiency that prior art exists, and a kind of room temperature silicon sulfide rubber composite nano-material antifouling flush paint that improves the pollution flashover voltage function is provided.
Room temperature silicon sulfide rubber composite nano-material antifouling flush paint of the present invention is achieved by following technical proposals, and described coating comprises following component, and following component concentration is by accounting for the weight percent meter that coating is formed:
Major ingredient: dihydroxyl gathers ethylene methacrylic radical siloxane 3%～10%;
Dialkyl polydimethylsiloxane 12%～20%;
Filler: nano silicon 0.3%～10%;
Nano titanium oxide 0.3%～10%.
Powdery mica 0%～3%;
Powdery aluminium hydroxide 0%～12%;
Powdery antimonous oxide 0%～3%;
Nm-class active calcium carbonate 0%～1%;
Thinner: 50%～65%.
Room temperature silicon sulfide rubber composite nano-material antifouling flush paint of the present invention comprises following auxiliary agent, and following component concentration is by accounting for the weight percent meter that coating is formed:
Methyl tributanoximo silane 0.5%～2.5%;
Four Diacetylmonoxime base silanes 0.1%～0.5%.
Methyl tri acetylacetonate oximino silane 0%～0.5%;
Stannous octoate 0%～0.02%.
Thinner is zellon or trichloroethane in the room temperature silicon sulfide rubber composite nano-material antifouling flush paint of the present invention.
Room temperature silicon sulfide rubber composite nano-material antifouling flush paint of the present invention is the brushing material that is applied to the high voltage electric power equip ment insulator surface, is to have utilized the peculiar surface hydrophobicity of silicon rubber after the sulfuration and the transportable property of small molecules siloxanes.This distinctive hydrophobic function can make the shipwreck attached to the physical aspect of this material surface be dispersive globule shape to form successional moisture film.When practical application, insulator surface owing to coated silicon rubber had above-mentioned hydrophobic function.Under certain natural condition, the power equipment insulator surface just be difficult to form constitute by dust and rainwater, continuity electroconductibility moisture film.Having reduced simultaneously or reduced can be for the flashover passage of discharge.Pollution flashover accident in the time of so just can reducing or avoid the power equipment operation reduces or has reduced the direct and indirect economic loss that is caused by pollution flashover accident.
Inquire into and experimental summary through extensive studies, the room temperature silicon sulfide rubber composite nano-material antifouling flush paint that employing is in scientific and technological forward position can well improve the soaking-resistant special property, by adding nanometer fineness filler the colloid internal capillaries is narrowed down, permeation rate slows down, and reaches the purpose that water resistance improves.And can make the corresponding raising of other application indexes.The product that formulation ratio after determining is produced can make coating hydrophobic character after water logging is steeped 96 hours, need not pass through time of recovery, and hydrophobic still keeps the HCl level.
The optimization index that room temperature vulcanized silicone rubber is equipped with behind the Nano filling is as follows: (with the prior art numeric ratio)
| Project | Empirical value | Prior art |
| 1, the resistant lightning is pressed | Be increased to U1/U2=2.03 (UI is for there being coating, and U2 is no coating) | U1/U2 is not less than 1.5 |
| 2, dielectric strength | Be increased to 24.5kV/mm | Be not less than 18.0kV/mm |
| 3, tearing toughness | Be increased to 5.6kN/m | Be not less than 3.0kN/m |
| 4, anti creepage trace and galvanic corrosion | Be increased to the TMA3.5 level | Be not less than the TMA2.5 level |
| 5, combustibility | Be increased to the FV-0 level | The FV-2 level |
| 6, sticking power | Be increased to 1 grade | Be not less than 2 grades |
| 7, hydrophobic nature | The water logging bubble is after 96 hours, and hydrophobic nature is not lost | 96 hours/recovery of water logging bubble 24 hours, hydrophobic nature is not less than the HC2 level |
