The invention relates to the technical field of paint, in particular to low-reflectivity full-dull black paint for a vehicle-mounted HUD system and a preparation method of the low-reflectivity full-dull black paint. The low-reflectivity full-dull black paint is used on a vehicle-mounted HUD light source cover (base material PC + PBT) to replace current mainstream black flocked cloth, the black paint selects resin with good chemical resistance and adhesive force and is matched with pigment and filler with high light absorption efficiency and large specific surface area to prepare the dull black paint with the reflectivity lower than 1.0, and the black paint is good in chemical resistance, good in aging resistance and good in weather resistance. And after being used for several years, the display definition cannot be reduced, and the performance can meet the requirements of customers.

    本发明涉及涂料技术领域,具体是一种用于车载HUD系统的低反射率全消光黑色漆及其制备方法。本发明低反射率全消光黑色漆用于车载HUD光源罩(基材PC+PBT)上面,替代现在主流使用黑植绒布,此黑色漆选用耐化性和附着力好的树脂,再配以吸光效率高,比表面积大的颜填料,调制出反射率低于1.0的消光黑漆,该黑漆耐化学性能好,耐老化性好,使用几年后显示清晰度不会下降,性能都能满足客户的要求。
