摘要
建筑物门窗玻璃、汽车玻璃等对可见光的透过性有较高的要求,但在满足采光需求而使可见光透过的同时,太阳光的热量也随之传递。因此,对室内温度和空调制冷能耗产生很大影响~([1])。为了节约能源,窗户透明隔热涂料受到了研究者的广泛关注。透明隔热涂料是以透明树脂为基料,与具有隔热功能的纳米粉体和各种助剂配置而成的功能性涂料。本研究采用有机硅树脂为基体,二氧化钒(VO_2)为阻隔红外的功能纳米粉体,通过添加适量助剂进行调配制得涂料,涂覆在玻璃基板上。实验结果表明,在一定膜厚的条件下,涂膜调控效率可达17.7%,可见光透过率为40%以上,硬度2H,附着力1级。该涂层具有在室温左右对红外光反射进行控制的功能,当温度高于VO_2的相变温度,可有效阻止太阳光中的红外线透过;而当温度低于相变温度时,可保证太阳光中的红外线透过,从而实现智能调控的作用。该涂料综合性能优异,具有广泛的应用价值。
Glazing for buildings and automotive glass need high visible transmittance.But the heat of the sunlight also transmit that has a significant influence on room temperature and the energy consumption of air condition.In order to save energy,transparent adiabatic coatings are needed,which are consisted of resin,nano-powders within heat-resistance and variety of additives.In our study,the organic silicon resin is the matrix,and VO_2 is the functional naon-powders to obstruct the infrared light.Experimental results show that under certain conditions of film thickness,the coating with the hardness of 2H shows regulatory efficiency is up to 17.7%,and the transmittance of the visible light is above 40%.The coating has the ability to reflect the infrared light around the room temperature.When the temperature is above the phase-transition temperature of VO_2,the coating can effectively block the infrared light.Inversely,if the temperature is less than the phase-transition temperature of VO_2,the coating can allow the infrared light to penetrate.The coating has excellent performance and will have extensive value in use.
