Abstract
The invention provides a greenhouse vulcanized silicone rubber anti-contamination flashover coating which is characterized by comprising the following raw material components in parts by weight: 12-20 parts of dihydroxy polydimethylsiloxane, 3-10 parts of dihydroxy polymethylvinylsiloxane, 0.5-10 parts of silicon dioxide, 0.5-10 parts of titanium dioxide, 0.5-12 parts of magnesium hydroxide, 0.5-2 parts of activated calcium carbonate, 0.5-4 parts of barium sulfate, 50-65 parts of diluting agents and 1-10 parts of cross-linking agents. A coating layer formed by the greenhouse vulcanized silicone rubber anti-contamination flashover coating can enable that a continuous conductive water film formed by dust and rainwater is difficult to form on the surface of the insulator of electric equipment, and a flashover passage which can be used for discharge is decreased or descended, in such a way, contamination flashover accidents during the operation of the electric equipment can be reduced or prevented, and the direct and indirect economic loss caused by the contamination flashover accidents is reduced or lowered. According to the invention, the hydrophobicity can be still kept at an HC1 grade without needing recovery time after the coating layer is soaked for 96 hours through water, the contamination flashover resistant voltage achieves U1/U2:2.24, and the dielectric strength achieves 25 KV/mm.
Description
Technical field
The invention belongs to technical field of coatings, relate in particular to a kind of greenhouse sulphurated siliastic antifouling flush paint.
Background technology
Room temperature vulcanized silicone rubber is because it has unique hydrophobic nature, migration of hydrophobicity is used as anti-pollution flashover material of new generation.Owing to there being oligopolymer and the subset of a large amount of hydrophobicities in room temperature vulcanized silicone rubber; make reactive force between silastic surface and water molecules be less than the force of cohesion of water molecules; water molecules forms and is greater than the wetting angle of 90 °, and moisture film cannot launch, and presents discontinuous globule state and has hydrophobicity; Room temperature vulcanized silicone rubber is that to have hydroxy-end capped polydimethylsiloxane be base glue, and wherein general all uncrosslinked lower molecular weight silica that contains in various degree burn segment, and these low molecules play hydrophobicity migration and the effect recovering to silicon rubber.Because the main body of room temperature vulcanized silicone rubber antifouling flush paint is the macromolecule organic silicon rubber, after self cure or film-forming, the sticking power between coating and insulator is lower, and coating hardness is less, easily scratches; And long-term exposure is in open air, is subject to the effects such as uviolizing, electromagnetic field and dust storm, the life-span of its anti-pollution flashover is not long.Under dirty area and bad weather condition, also may produce dry belt discharge phenomenon.It is to be improved aspect high temperature resistant low temperature, weather, radiation hardness, anti-electric-arc electric insulating quality.
Summary of the invention
In order to solve the problems of the technologies described above, the invention provides a kind of greenhouse sulphurated siliastic antifouling flush paint, it is characterized in that the each component of raw material by weight mark be the poly-ethylene methacrylic radical siloxane 3-10 part of dialkyl polydimethylsiloxane 12-20 part, dihydroxyl, silicon-dioxide 0.5-10 part, titanium dioxide 0.5-10 part, magnesium hydroxide 0.5-12 part, activated Calcium carbonate 0.5-2 part, barium sulfate 0.5-4 part, thinner 50-65 part and linking agent 1-10 part.
The diameter of particle of described silicon-dioxide, titanium dioxide, magnesium hydroxide, activated Calcium carbonate, barium sulfate is 20-60nm.
Described thinner is zellon.
Described linking agent is one or more of methyl tri acetylacetonate oxime silane, four Diacetylmonoxime base silanes, vinyl three Diacetylmonoxime silane, stannous octoate
Beneficial effect of the present invention is: major ingredient adopts dialkyl polydimethylsiloxane and the poly-ethylene methacrylic radical siloxane of dihydroxyl, the coating forming has the transportable property of surface hydrophobicity and small molecules siloxanes, this hydrophobic function can make the shipwreck of the physical aspect that is attached to this material surface be the globule shape of dispersion to form successional moisture film, Electric Power Equipment Insulation surface is just difficult to formation is made up of dust and rainwater, continuity electroconductibility moisture film like this, and having reduced simultaneously or reduced can be for the flashover passage of electric discharge.Pollution flashover accident so just can reduce or avoid power equipment operation time, reduces or has reduced the direct and indirect economic loss being caused by pollution flashover accident.The present invention can make coating need not pass through time of recovery after 96 hours through water soaking, and hydrophobic still keeps HC1 level, and resistance to pollution flashover voltage reaches U1/U2:2.24, and dielectric strength reaches 25KV/mm.
