Description
Technical field
Patent of the present invention relates to the metallic paint field, particularly a kind of temperature automatically controlled infrared radiation coating and application thereof.
Background technology
Present existing high-power LED street lamp all adopts aluminum alloy materials basically; do not take any protection and decorative painting as yet; more adopt functional applications such as heat radiation is temperature automatically controlled and antistatic; high-power LED street lamp is the new high-tech product that just occurs recent years; be faced with very arduous environmental issue; heat transfer, heat conduction and heat dissipation problem, and be faced with new protection against corrosion and antistatic requirement.
Commercially available scarcely environmental protection of metal or alloy material antiseptic antirust decorative coating at present belongs to solvent based coating, and its solvent generally all is that with the thinner as pigment, paint etc., content is higher based on benzene class organic solvents such as dimethylbenzene.Dimethylbenzene is a kind of colourless transparent liquid, and is water insoluble, is dissolved in ethanol and ether, toxic, volatile, but polluted air and contaminate environment, serious harm human body health.Simultaneously, this class coating products overwhelming majority contains plumbous system and chromate pigments, also can cause environmental pollution and harm humans health to environment.In recent years, occurred the anti-corrosive antirusting paint of some water-baseds on the market, mainly be divided into two major types: be i.e. latex type and water-soluble type.But because the former poor stability, rustless property is undesirable, from the requirement of the actual expectation of people bigger gap is arranged still; The latter is the antiseptic and rustproof paint of drying-type, its drying condition generally all 140 ℃ * more than 30 minutes, energy consumption is higher, also needs special-purpose drying plant, its rust-proof effect is also undesirable, its salt mist experiment seldom has and reaches 300 hours product.Therefore, now on the market, still be main flow with traditional rust-inhibiting paint product, poor-performing, price are also cheaper, and environmental pollution is also serious, though product innovation in recent years reduces and has improved the pollution to environment relatively, but owing to technical reason, the stability and the performances such as salt spray resistance, corrosion resistance of its product are still unsatisfactory, do not meet at present in the world the development trend to antiseptic and rustproof product requirement environmental protection and health performance excellence.
High-power LED street lamp is the market new lover who grows up on the world market in recent years, belongs to green semiconductor lighting industry, and it has energy-saving and cost-reducing, safety and environmental protection, brightness is big, the life-span is long, photochromic soft many excellent characteristics such as comfortable.Along with the aggravation of world energy sources crisis, each state is all in the way of seeking to solve energy dilemma, and an approach is to seek the utilization of new and renewable sources of energy; Another is to seek new power-saving technology.Save energy is the important component part that china natural resources is saved fundamental state policy, also is a long-range strategy task of Chinese national economy and social sustainable development.Semiconductor lighting by universally acknowledged be the important channel of energy-saving and environmental protection, be one of the high-tech sector of tool development prospect of 21 century.LED possess power saving, environmental protection do not have mercury, the little response of volume fast, high shatter-proof, can be applicable to low temperature environment, light source have directivity, cause the light evil less and develop the color, advantage such as colour gamut is enriched.China's street lighting electricity consumption replaces as adopting great power LED, and comparable original high-power traditional lighting street lamp can be saved 1/3 electric consumption on lighting, and energy-saving effect is very obvious.And in the electrical production of China about 80% for thermal power generation, need burning a large amount of raw coal and oil, produce a large amount of dust and CO
2, SO
2Deng gas, environmental pollution is serious, and the application of high-power LED street lamp product can reduce electricity usage, significantly reduces emission of carbon-dioxide and environmental pollution, can play real energy-saving, emission-reducing, environment friendly effect.Yet the high-power LED street lamp quality that occurs on the market is uneven, lack the unified world and home products standard again, thereby the situation that dragons and fishes jumbled together appears, technical products that market demand is new such as high-power LED street lamp solve problems such as the heat radiation of high-power LED street lamp and antistatic, protection against corrosion with temperature automatically controlled infrared radiation coating.
