Abstract
The invention provides a kind of antifouling work coatings applied to power equipment, belong to coating composition technical field, it is prepared by the raw material of following weight parts：30 ~ 40 parts of silicon rubber, 20 ~ 30 parts of fluorine silicon resin, 10 ~ 20 parts of titanate coupling agent, 2 ~ 7 parts of nano molecular sieve, 1 ~ 5 part of diatomite, 5 ~ 10 parts of zinc oxide, 0.01 ~ 0.06 part of tributyl phosphate, 2 ~ 7 parts of ethyl acetate, 2 ~ 7 parts of phosphate modified acrylic emulsion, 0.1 ~ 0.5 part of dispersant, 0.001 ~ 0.004 part of surfactant, 0.2 ~ 0.8 part of curing agent, 30 ~ 50 parts of propylene glycol methyl ether acetate.Averaged static contact angle >=150 ° of gained composite coating of the invention, minimum static contact angle >=143 °, and also the mechanical performance of coating, self-cleaning property are excellent, suitable for power equipment external insulation antifouling work.
Description
Technical field
The invention belongs to coating composition technical field, and in particular to a kind of antifouling work applied to power equipment, which insulate, to be applied
Material.
Background technology
Pollution flashover refers to that dirt particle in air etc. deposits to the insulator surface of longtime running out of doors, gradual shape
Into pollution layer, under the meteorological conditions such as light rain, snow, mist, haze, dew, pollution layer is moistened gradually, and soluble substance therein is gradually dissolved in
Water, and insulator surface formed one layer of conducting film, so as to add surface conductivity, make decreasing insulating, caused by absolutely
The flashover electric discharge (abbreviation pollution flashover) of edge wetted surface.The three big principal elements for triggering pollution flashover are insulator surface contamination, filth
Layer moistening and voltage effect, pollution flashover process mainly include 4 stages：Insulator surface contamination, filthy layer surface humidify, dry area with
Local arc is formed, flashover.
At present because the deterioration of environment, pollution flashover accident take place frequently, great economic loss and potential safety hazard are caused, is had a strong impact on
The production and living of people, effective measures are presently the most in insulator surface coating antifouling flush paint, therefore antifouling flush paint makes
With extensive, dosage is big, but the combination property such as the hydrophobicity of the antifouling flush paint used at present, mechanical performance is poor, and service life is short,
Thus country need to periodically stop every year high-voltage line transmission of electricity, expend substantial amounts of manpower and materials antifouling flash coating layer is cleaned, brushed,
Safeguard etc., it is costly.
Publication No. be CN101597463A patent disclose a kind of fluorinated silicone rubber anti-pollution flashover coating for extra-high voltage and
Its preparation method, it is formulated by mass percentage this fluorinated silicone rubber anti-pollution flashover coating (abbreviation FRTV), fluorosioloxane rubber：5~
30%；Silicon rubber：10~30%；Nanoscale gas-phase silica：4~8%；Composite flame-retardant agent：0.5~8%；Curing agent：0.2~0.5%；Urge
Agent：0.01~0.05%；Antioxidant：0.02~0.08%；Levelling agent：2~8%；Defoamer：0.2~0.4%；Pigment：0.1~
0.5%；Solvent：30 ~ 60%, described composite flame-retardant agent, it is made up of inorganic matter aluminium hydroxide and organic matter decabromodiphenyl oxide, wherein
Inorganic matter aluminium hydroxide：1~6%；Organic matter decabromodiphenyl oxide：0.5~3%.The Paint preparation technology that the invention provides is simple, has
Good weatherability, oil resistivity, longer service life.The antifouling flush paint hydrophobic performance is general, and mechanical performance is poor, and
Although preparation method step is simple, practical operation difficulty is big.
Publication No. CN106811116A patent discloses a kind of processing of the long-acting super-hydrophobic antifouling flush paint of spacetabs type
Technique, end hydroxypropyl fluorinated polysiloxane, end hydrogen-based polysiloxanes and hydrophobic type gas-phase silica is prepared first, then by end
Hydroxypropyl fluorinated polysiloxane, end hydrogen-based polysiloxanes and 107 silicon rubber, nano zine oxide, oily amino oleic acid ester, mica powder,
Aluminium hydroxide is added to stirred in mixer after ground 3 ~ 4 times on three-roller, obtain uniform sizing material；Then by equal spin coating
Material adds in kneader and is warming up to 145 ~ 150 DEG C after addition hydrophobic type gas-phase silica, mediates 1 ~ 2 hour, is cooled to 20 ~ 30
DEG C, ketoxime type crosslinking agent, dimethylaminopropylamine, silane coupler and organic solvent are then added thereto, after stirring
To the long-acting super-hydrophobic antifouling flush paint of spacetabs type；Coating as obtained by the preparation method of the invention is by holding hydroxypropyl fluorine-containing poly-
Siloxanes and end hydrogen-based polysiloxanes are combined the purpose that can reach sustained release antifouling work, and can significantly improve hating for coating
Water migration.But the especially mechanical breaking strength of mechanical performance of antifouling flush paint that the technique is obtained is relatively low, during solidification
Between it is longer.
The content of the invention
In view of this, the technical problems to be solved by the invention are to provide a kind of antifouling work applied to power equipment and insulated
Coating.
To achieve the above object, the technical solution adopted in the present invention is：
A kind of antifouling work coatings applied to power equipment, it is prepared by the raw material of following weight parts：Silicon rubber 30 ~ 40
Part, 20 ~ 30 parts of fluorine silicon resin, 10 ~ 20 parts of titanate coupling agent, 2 ~ 7 parts of nano molecular sieve, 1 ~ 5 part of diatomite, zinc oxide 5 ~ 10

Step S4：By silicon rubber, fluorine silicon resin, titanate coupling agent, propylene glycol methyl ether acetate and phosphate modified acrylic acid
Emulsion is mixed, and 1500rpm is stirred 1.5 ~ 2 hours, obtains the first mixed system；
Step S5：Be sequentially added into first mixed system dried zinc oxide of step S3, nano molecular sieve and
Diatomite, and stirred 1 ~ 1.2 hour, 1 ~ 1.5 hour and 1.5 ~ 2 hours under the conditions of 10000 ~ 12000rpm successively, obtain
Two mixed systems；
Step S6：Dispersant is added in second mixed system, 1500 ~ 2000rpm grinds 1 ~ 2 hour, then added successively
Entering ethyl acetate and remaining surfactant, 1500 ~ 2000rpm is ground 1 ~ 2 hour, is eventually adding curing agent, 1500 ~
2000rpm is ground 1 ~ 2 hour, is produced.
9. a kind of preparation method of antifouling work coatings applied to power equipment as claimed in claim 8, its feature exist
In：The frequency of the ultrasonic wave is 25 ~ 30kHz, and power is 300 ~ 500W.
