Problems solved by technology

[0004] At present, the existing reflective coatings use a large amount of metal raw materials to improve the reflective performance, but the reflectivity of visible light and near-infrared light, thermal infrared emissivity and stability are poor, the chemical resistance and workability are not good, and the heat dissipation performance is not good. Those skilled in the art urgently need to develop a new type of aging-resistant reflective coating for street lamps with significant high reflectivity to meet the above higher requirements

Abstract

The invention discloses a preparation method of an anti-aging reflective coating for a high-reflectivity street lamp, and belongs to the technical field of coatings; the preparation technique is simple, the prepared coating has the advantages of functions of blocking, reflecting and radiating light heat of lamplight, heat insulation and cooling of the lamp, energy saving, consumption reduction, heat insulation, water resistance, corrosion resistance, short construction period and quick effect, and heat of lamplight cannot be accumulated on the surface of the lamp, the temperature cannot rise,heat can be automatically radiated and heat is dissipated to lower the temperature. Heat on the surface of the lamp is radiated into air, the temperature of the lamp is reduced, the service life of the lamp is prolonged, and the coating has high visible light and near-infrared light reflectivity, high thermal infrared emissivity, high stability and other comprehensive performance; meanwhile, the coating has good physical performance, chemical performance and good constructability, and is applied in industries relating to electronics, traffic lighting, communication equipment, power products and other industries.

Description

technical field [0001] The invention belongs to the technical field of coatings, and in particular relates to a preparation method of an anti-aging reflective coating for high reflectivity street lamps. Background technique [0002] With the increase in the use of high-intensity discharge lamps, the use of LED lamps will be widely used, and, as a common lighting source, it is widely used in street lamps, and there is a widespread need to continue to improve LED lighting efficiency and extend The question of service life. For example, ammonia-filled incandescent lamps can reduce heat loss and improve luminous efficiency, which can save about 10% of electricity compared with ordinary incandescent lamps. Coating a new reflective coating on the inner surface of the bulb can reduce the power consumption of the bulb by 60%. Coating reflective paint on the inner surface of the bulb can focus the infrared radiation on the filament in the center of the bulb, which can reduce the pow...
