一种聚碳酸酯后角窗玻璃及其制备方法
摘要：
本发明公开了一种聚碳酸酯后角窗玻璃及其制备方法，属于汽车玻璃领域技术领域，该后角窗玻璃包括后角窗、包覆在后角窗四周的黑边区域及涂覆在后角窗两面的保护涂层，所述后角窗由注塑PC板材热压切割成PC后角窗，所述黑边区域为PC专用油墨丝网印刷而成，所述保护涂层为有机硅涂层，所述的有机硅涂层采用淋涂的方式涂覆在PC后角窗的两面；本发明的PC玻璃的两面的有机硅涂层，提高了PC玻璃的耐磨性和耐气候性，其CF-10磨轮，500g,500cycle,Taber耐磨性的△Haze值在2％-5％，氙灯老化耐气候性能达到4500KJ/m2以上，这些都满足欧洲ECE R43塑料车窗法规要求，使得PC玻璃后角窗真正进入实用领域。
摘要（英）：

The invention discloses polycarbonate rear corner window glass and a preparing method thereof, and belongs to the technical field of car glass. The rear corner window glass comprises a rear corner window, a black edge area coated on the periphery of the rear corner window and protection coatings coated on the two faces of the rear corner window. The rear corner window is formed in a manner that aninjection molded PC board is subjected to hot pressing cutting to form the PC rear corner window, the black edge area is formed through printing of a PC special ink silk screen, the protection coatings are organic silicon coatings, and the two faces of the PC rear corner window are coated with the organic silicon coatings in a sprayed manner. Due to the organic silicon coatings on the two faces of the PC glass, wear resistance and weather fastness of the PC glass can be improved, for a CF-10 grinding wheel, delta Haze value of 500 g, 500cycle, Taber wear resistance ranges from 2 to 5%, the aging weather-proof property of an xenon lamp can reach 4500 Kj/m<2> or above, the Europe ECE R43 plastic vehicle window regulatory requirements can be met, and the PC glass rear corner window really enters in the practical field.
