Abstract
The invention discloses a kind of improvement long-acting super-hydrophobic anti-pollution flashover coatings of 3 type slow-releases, in parts by weight, it is made of following raw material: 35 ~ 45 parts of hydroxypropyl fluorinated polysiloxane of end, 20 ~ 30 parts of hydrogen-based polysiloxanes of end, 107 55 ~ 65 parts of silicon rubber, 20 ~ 30 parts of hydrophobic type gas-phase silica, 3 ~ 5 parts of nano zine oxide, 2 ~ 4 parts of oily amino oleic acid ester, 4 ~ 6 parts of wollastonite in powder, 1 ~ 3 part of ketoxime type crosslinking agent, 5 ~ 10 parts of dimethylaminopropylamine, 1 ~ 2 part of silane coupling agent, 3 ~ 6 parts and 165 ~ 175 parts of organic solvent of aluminium hydroxide；The long-acting super-hydrophobic anti-pollution flashover coating mechanical performance of 3 type slow-release of improvement of the invention is strong, long service life, it can reach 15 years, good flame resistance can reach FV-0 grades, and salt spray resistance ageing properties are good, stain resistant is had excellent performance, its validity still can be played in haze polluting weather, reaches expected anti-fouling effect, avoids the generation of pollution flashover accident.
Description
Technical field
The present invention relates to technical field of coatings, specifically a kind of improvement long-acting super-hydrophobic anti-pollution flashover coating of 3 type slow-releases.
Background technique
Pollution flashover accident coverage is wide, and power off time is long, seriously threatens the operational safety of power transmission and transforming equipment, especially winter
In season, the pollution flashover tripping times that nationwide integrated power grid occurs are thousands of, almost lead to provincial power network therefore off-the-line sometimes.Antifouling work
Measure is nothing more than mainly having: the measure of taking tune to climb, insulator cleaning, using composite insulator, coating RTV coating (room temperature sulphur
SiClx rubber) this 4 kinds.Integrated survey compares above-mentioned Flash Decontamination Measurements, it can be seen that coating RTV coating is most economical, effect
A kind of best effective measures.The route for being especially coated with RTV in national large area pollution flashover accident in 2001 does not have
There is generation pollution flashover accident, therefore RTV has obtained higher rating.
However, although the introducing of RTV coating alleviates the pollution flashover problem that electric system is on the rise, current RTV
Coating property is still relatively low, and the adhesive force of coating first is weak, and wear-resisting property is poor, poor corrosion resistance, due to poor adhesive force, is tieing up
The effect of external force in servicing operations is repaired, coating is easy to be detached from；Secondly because the structure composition problem of itself, the machinery of its own
Performance is easy to appear peeling in actual use, is cracked, falls off if elongation, breaking strength and tearing strength are all lower
Phenomenon；Again, current RTV coating surface is easily absorbing and accumulates dust, dirty after loose filth reaches certain thickness
The channel of dirty inside water flow easy to form and the stagnant area of large area, ultimately form flashover channel, lead to the hair of pollution flashover event
It is raw；In addition, still suffering from temperature change, sleet frost and sunshine since RTV coating will not only bear the effect of electric field and wind-force
Erosion, the performance of RTV coating is gradually reduced over time, and it is short to be easy aging service life, and periodic maintenance is needed to protect
It supports and even sprays again, bring significant limitation to its use.
Therefore, a kind of high-performance, slow-release, the novel antifouling of long-life are targetedly developed and dodges coating, in superelevation
It presses, have important practical significance in the antifouling work of extra-high voltage grid route, a large amount of construction fund and operation dimension can be saved
Shield expense creates better Social benefit and economic benefit.
Summary of the invention
To solve the above problems, the object of the present invention is to provide a kind of long-acting super-hydrophobic antifouling works of 3 type slow-releases of improvement to apply
Material.
The present invention to achieve the above object, is achieved through the following technical solutions:
A kind of improvement long-acting super-hydrophobic anti-pollution flashover coating of 3 type slow-releases is made of following raw material in parts by weight: end hydroxyl
35 ~ 45 parts of propyl fluorinated polysiloxane, 20 ~ 30 parts of hydrogen-based polysiloxanes of end, 107 55 ~ 65 parts of silicon rubber, hydrophobic type gas phase hard charcoal
