Abstract
The invention provides a nanometer strengthening fluoride silicone rubber long-acting anti fouling and flashing coating material (nano PRTV coating material) which is used on an external insulation layer of a power system high pressure transmission and transformation device. The coating is composed of the following compositions (weight portion) of 20-40 percent of hydroxyl-fluoride containing polysiloxane, 2-5 percent of small molecular siloxane, 1-6 percent of cross linker, 0.02-1 percent of catalyst, 2-6 percent of nano silicon dioxide, 4-6 percent of decabromodiphenyl ethane, 1-2 percent of pigment and 30-50 percent of solvent. The coating provided by the invention is provided with perfect flame retardancy, solvent resistance, oil resistance, high and low temperature resistance and good self-cleaning performance. The surface of the coating material is smoother than dirt flash preventing coating material. Compared with the dirt flash preventing coating material, the coating material of the invention is greatly improved in aspects of hydrophobic migration speed, proportionality, sustainability, etc. Once filming can be realized. With the service life of more than 20 years, the coating material can be used permanently.
Description
Technical field
The invention belongs to the chemistry painting industry technical field, further relate on the power equipment external insulation layer, use in anti-pollution flashover field, have quick, balanced, persistent migration of hydrophobicity, good flame retardant resistance and persistent ageing resistance can reach the nanometer enhanced type fluorosilicone rubber long-acting anti-fouling flashing coating (being called for short nanometer PRTV coating) more than 20 years work-ing life.
Technical background
Coating RTV antifouling flush paint facts have proved and can have been played positive anti-pollution flashover effect on the power equipment insulation layer.The difference of RTV antifouling flush paint prescription, its mass discrepancy is very big, and its anti-pollution flashover effect and economic benefit difference are also very big.The RTV antifouling flush paint has 20 multinomial technical indicators, and its core index is: migration of hydrophobicity, ageing resistance, flame retardant resistance etc.
At present, the RTV antifouling flush paint major ingredient itself that generally use in market contain some amount small molecules hydrophobic group, this small molecules hydrophobic group has the migration of hydrophobicity characteristic, the migration of hydrophobicity characteristic is the dominant mechanism of RTV antifouling flush paint.The RTV antifouling flush paint is coated in insulator surface because suffer wind for a long time, erosion such as day spill, drench with rain, small molecules hydrophobic group runs off gradually, acquire a certain degree, group runs off totally, the inevitable forfeiture thereupon of coating migration of hydrophobicity characteristic, and coating will not have anti-pollution flashover effect this moment.The employed prescription of domestic most RTV antifouling flush paint manufacturers is all according to People's Republic of China's power industry (DL/627-2004) standard design, can't satisfy fast-developing ultra-high voltage, the needs of super ehv power transmission equipment generally more than 5 years the work-ing life of coating.
The RTV single-component hydrophobic, long-acting and anti-fouling flashing coating patented technology (application number: 00112886.8) that Tuoli Chemical Industry Co. Ltd., Chengdu has, though have certain flame retardant properties, but owing to only be added with a spot of aluminium hydroxide and magnesium hydroxide in the coating, fire-retardant rank is very low.If make coating reach FV-0 level flame-retardant standard, add-ons such as aluminium hydroxide should account for more than 40% of solids coatings.Think in " the transregional electrical network power transmission and transformation equipment outer insulation of State Grid Corporation of China with antifouling flush paint instruction principle ", " ... aluminium hydroxide etc., when filler was too much, some performance increased, but antifouling property descends ".So, no longer aluminium hydroxide etc. is joined in the antifouling flush paint as fire retardant at present, also just because of the not high reason of the fire-retardant rank of this coating, also have only more than 5 years work-ing life.
The patented technology of Xibei Power Test Inst. " nanometer enhanced type RTV long-acting and anti-fouling flashing coating " (patent No. ZL200410026092.7), though anti-fouling flashover performance is outstanding, but flame retardant properties is poor, and only have 8 years work-ing life, does not satisfy the requirement of power department to work-ing life.
Summary of the invention
In order to overcome existing RTV antifouling flush paint above shortcomings, the invention provides a kind of nanometer enhanced type fluorosilicone rubber long-acting anti-fouling flashing coating (nanometer PRTV coating).
Prescription of the present invention comprises following component (weight): terminal hydroxy group fluorinated polysiloxane (FRTV) 20-40%, small molecules siloxanes 2-5%, linking agent 1-6%, catalyzer 0.02-1%, nano silicon 2-6%, ethane-1,2 couple (pentabromobenzene) 4-6%, pigment 1-2%, solvent 30-50%.
Wherein, terminal hydroxy group fluorinated polysiloxane viscosity is 1200～2000cp; [0-Si] key number n=10～100 in the small molecules siloxane molecule structure; The molecular weight of ethane-1,2 pair (pentabromobenzene) is 971.2.
Beneficial effect of the present invention mainly shows:
The first, the present invention is to be major ingredient with terminal hydroxy group fluorinated polysiloxane (FRTV) macromolecular material, adds special assistant and filler etc., processes through special process.Terminal hydroxy group fluorinated polysiloxane (FRTV), its molecular structure is:
FRTV compares with RTV, and except that other performance is identical, is different from the outstanding feature of RTV and is: the solvent resistance that (1) is good, long period of soaking do not steep and rise in all kinds of SOLVENTS, and be harmless, suits to use under abominable chemical atmosphere environment; (2) superior oil-proofness, coating runs into various oils, non-scale, does not come off, do not chap, and has thoroughly solved the RTV antifouling flush paint and has made coating peeling this difficult problem that lost efficacy because of power equipment (as transformer) seepage oil.(3) You Yi high and low temperature resistance especially is fit to promoting the use of of the different climatic condition in China north and south vast in territory; (4) good self-cleaning makes coatingsurface more smooth than RTV.
The second, add small molecules hydrophobic group～small molecules siloxanes, its molecular structure is:
The present invention adds a certain proportion of hydrophobic group～small molecules siloxanes in formulation for coating material, cause the migration of hydrophobicity speed of coating, migration of hydrophobicity persistence to improve greatly.When coat-thickness reached 0.4mm, the migration of hydrophobicity useful life of coating can be brought up to more than 20 years, and in 20 years, the migration of hydrophobicity of coating can keep good effect balancedly, constantly.
The 3rd, add the organism fire retardant: ethane-1,2 pair (pentabromobenzene), its molecular structure is: C14Br10H4
The quality of the flame retardant properties of antifouling flush paint directly influences the quality and the work-ing life of coating.The ethane-1,2 pair (pentabromobenzene) that the present invention adds is a kind of high insulating organism, and it is a kind of novel, wide spectrum, efficient, environment friendly flame retardant, has excellent thermostability and anti-ultraviolet property.Its addition is few, can not have influence on the various technical indicators of coating.
The present invention adds a spot of ethane-1,2 pair (pentabromobenzene), can make the flame retardant grade of coating not bring up to the FV-0 level, can withstand the impact of electric Halo, electrical spark lastingly, improved the work-ing life of coating, and can in 20 years, make coating continue to keep the fire-retardant state of FV-0 level.
