Description
(1), technical field
The present invention relates to a kind of new purposes of add-on type fluosilicic rubber, the particularly application of room temperature vulcanization add-on type fluosilicic rubber (PRTV) on insulator.
(2), background technology
Insulator is that a kind of inorganic oxide is the power equipment of chemical composition, its intensity height, and good insulating is still being brought into play irreplaceable effect in electric power system especially high-pressure system.But along with serious day by day air pollution, be that the hydrophilic defective of porcelain insulator of material just becomes fatal with the inorganic oxide, pollution flashover accident easily takes place.
(3), summary of the invention:
In order to overcome the shortcoming of prior art, the present invention is the application of room temperature vulcanization add-on type fluosilicic rubber (PRTV) on insulator, improves resistant and dodges ability.
The present invention is the application of room temperature vulcanization add-on type fluosilicic rubber (PRTV) on insulator.Fluosilicic rubber is the substituent organosilicon element polymer of fluorine polymer, and excellent performance generally is processed as rubber through heat cure.
Room temperature vulcanization add-on type fluosilicic rubber (PRTV) is applied in has following advantage on the insulator: 1., good hydrophobicity and fast, balanced, lasting migration of hydrophobicity, the resistant lightning is pressed and is improved more than the twice; 2., dielectric strength is up to 30MV/m, the big TMA4.5 level of electrical erosion resistance, anti-flammability reaches the FV-0 level, arc resistant, can effectively protect electroceramics equipment not to be damaged under abnormal conditions; 3., mechanical strength height.Adhesive force is good, acid and alkali resistance, salt and chemical mediator corrosion, and oil resistance is good; 4., UV resistant, ozone, the opposing environmental attack, non-scale does not ftracture, and reaches useful life more than 20 years; 5., low-friction coefficient, have antistick characteristic, self-cleaning is good, conventional maintenance exempt from the phase cleaning; 6., room temperature vulcanization, in-place molding, easy to use, satisfy the needs of the on-the-spot anti-soil technology measure of power transmission and transforming equipment.
(4), embodiment
The present invention is the application of room temperature vulcanization add-on type fluosilicic rubber (PRTV) on insulator.
The preparation method of room temperature vulcanization add-on type fluosilicic rubber (PRTV) is: fluosilicic rubber and white carbon black filler carry out mixing in banbury, and glue furnacing temperature is 70-120 ℃, and pressure is lower than 0.3MPa.Elastomeric compound back mixing in mill evenly forms good flowability, and sizing material is dropped in the reactor, adds curing agent, stirs, and makes room temperature vulcanization add-on type fluosilicic rubber (PRTV).Described curing agent is the monomethyl siloxanes.The content of said components is fluosilicic rubber 55-70%, white carbon black 25-40%, monomethyl siloxanes 3-5%.
Pending power transmission and transformation insulator equipment surface is cleaned, decontamination and deoil, fat handles, with above-mentioned room temperature vulcanization add-on type fluosilicic rubber (PRTV) spraying for preparing or brush on the insulator equipment surface.Coating layer thickness is the 0.5-0.6 millimeter.Smooth, even, the no bubble of coating.
