Description
Technical field
The present invention relates to a kind of carbamide paint, particularly a kind of Weather resistant halogen-free flame retardant insulation polyureasCoating.
Background technology
In recent years, urban rail transit in China transport has obtained tremendous development, and quick, comfortable is electricChange city rail vehicle and brought earth-shaking variation to people's trip life; City rail vehicle is by being subject to electricityBow obtains electric energy from contact net, and pantograph is installed on vehicle roof, and train is in operation affected by environment,As haze weather, pantograph and roof position can often produce shelf depreciation, have a strong impact on traffic safety;Meanwhile, the upper contact net vehicle in operation, when pantograph bottom traction chain breakage, rides over city railThe roof of vehicle, contact net direct current can burn roof, will lead to great traffic safety accident. CauseThis, people expect spraying coatings to improve security performance in the pantograph region of city rule vehicle. ButThe insulated paint flow time adopting is short, and adhesive strength is inadequate, and the mode of spraying, insulated paint easily existsRifle head instantaneous solidification, if regular the having troubles of spraying equipment can cause bubble problem, thereby greatlyReduce insulating properties. Meanwhile, coatings of the prior art can not possess fire resistance simultaneously, resistance toMill performance is also inadequate, can not meet pantograph time between overhauls(TBO) needs and constantly dismantles pantograph and coating is carriedThe wear-resistant requirement going out.
Chinese invention patent CN1803918A provides a kind of fire-retardant, anlistatig unsaturated polyester (UP) treeFat, the fire-retardant filler such as decabromodiphenyl oxide, antimony oxide that contains halogen by interpolation reaches correspondingFire resistance; But on the one hand because halogen harm is large, this kind of product do not meet country on the other handEnvironmental protection policy, therefore can not extend to market. US Patent No. 6156825 is by adding ATH (hydroxideAluminium), one or more in phosphorus fire retardant or nitrogen combustion inhibitor obtain corresponding fire resistance (UL-94V-0 level), but the filler flame retardant effects such as ATH are poor, need a large amount of filling could obtain fire resistance, thisPlant way paint film property is declined, can not meet the demands; In addition, the interpolation of red phosphorus, affects paint filmForm and aspect.
Chinese patent CN102796319A provides a kind of expansion type flame-retardant, its formulaComposed as follows: acrylic resin 65～75%, halogen-free flame retardants 18～23%, flexibilizer 3～5%, phaseHold agent 3～5%, nano imvite 0.5～1%, lubricant 0.1～0.5%, antioxidant 0.2～0.5%;The part by weight that described halogen-free flame retardants is pressed 3:1:1 by APP, polyalcohol and melamine is mixedAfter closing, be coated again and process gained. This patent has realized the Halogen resistance that meets present national environmental protection policyCombustion, but flame-retardant system is expansion type flame-retarding, and stability, temperature tolerance are all poor, and cost is high.
Chinese patent CN104927649A provides a kind of anti-pollution flashover super-hydrophobic self-cleaning paint, and its feature existsIn, comprise following component: silicone glass cement, Kynoar powder granule, photochemical catalyst, are-tightAgent and organic solvent, 5～20wt% that described silicone glass cement is organic solvent, described KynoarPowder granule is 10～50wt% of described silicone glass cement, and described photochemical catalyst is described silicone glass10～50wt% of glue, described are-tight dose is 5～20wt% of described silicone glass cement. Adopt thisCoating is greater than 150 ° at the contact angle on surface of coating forming, and has good insulating properties, and breakdown voltage is largeIn 15kV/mm. This invention provides the application that has related to insulation field, but lays particular emphasis on the anti-of filmDodge dirty performance, do not relate to flame-retarded technology.
To sum up, develop the solvent-free discharge of a kind of environmental protection, fire resistance excellence, dielectric strengthHigh Weather resistant halogen-free flame retardant insulation carbamide paint is very necessary and urgent, and has wide cityField prospect.
Summary of the invention
