Functional additives with infrared reflective properties for automotive coatings
红外反射型功能助剂,让汽车涂料更环保
High temperatures in cars and thus high utilization of air condition is of constant environmental concern. Transparent IR-reflective particles can decrease the temperature in a car by roughly 27°C.
汽车的高温及因此导致的高空调利用率,一直是环保难题.而如今,含有透明红外反射颗粒的功能性助剂,能降低车内温度约27°C,从而有效缓解这个问题,
Infrared radiation primarily contributes to the rise in car temperature, prompting excessive reliance on air conditioning, which in turn increases fuel consumption and emissions of harmful gases. Various methods exist to mitigate this, including the application of inorganic pigments designed to reflect infrared radiation. However, these pigments often come with colour limitations. Hence, there’s a pressing need to develop a strategy capable of both reflecting infrared radiation and maintaining transparency in visible light, allowing for broader applicability across different colors. The goal is to reduce car temperatures, minimize air conditioning usage, and consequently decrease pollutant emissions.
红外线辐射是导致汽车温度升高的主因,高温又导致对空调的过度依赖,继而又增加了燃料消耗和有害气体的排放.要解决这个问题,现有手段则包括反射红外辐射型的无机颜料的研发,但这些颜料通常有颜色限制,因此,既能反射红外辐射又能在可见光下保持透明度的颜料的开发,成为了解决问题的关键.
将这种透明颜料用在不同颜色底漆上,能降低车内温度,尽量减少空调的使用,从而减少污染物的排放。
Proposed solution: silica nano and microparticles
The proposed solution involves utilizing silica nano/microparticles known for their transparency in the visible spectrum and high reflectivity to infrared radiation. These particles are engineered with spherical morphology and varied sizes and combinations to identify the most effective approach. The most successful material developed showcases an impressive ability to increase the infrared radiation reflection and decrease the temperature by roughly 27 °C. Beyond their exceptional temperature-reducing capabilities, silica micro/nanospheres offer the added advantage of preserving the standard quality of paint. This study demonstrates a promising alternative to minimize the use of air conditioning systems and subsequently reduce the emission of polluting gases.
建议方案：二氧化硅纳米和微粒
想实现透明效果,在可见光谱中具有透明度且对红外辐射具有高反射率的二氧化硅纳米粒/微粒则是优选.这些球形微粒,根据需求而大小各异组合变幻,能最高效的实现透明效果.其中最最优秀的,可以在增强反红外辐射的同时,将温度降低约27°C.除此之外,这种硅纳米还为底漆的稳定性提供保护.多管齐下,尽可能降低温度,减少车内空调的使用,减少污染气体的排放.
