The invention discloses a process improvement method for bonding a plastic back door and glass, The process improvement method comprises the following steps of: manufacturing an inner plate and an outer plate of the plastic back door with frame strips at the edges by an injection molding method, shielding the frame strips on the outer plate by using a shielding object, spraying low-temperature paint on the outer surface of the outer plate, and removing the shielding object after the low-temperature paint is completely cured; bonding the inner plate and the outer platein an aligned mode, and splicing the frame strips of the inner plate and the outer plateto form a bonding frame matching the glass; and finally, bonding the glasson the bonding frame. According to the invention, the outer plate and the inner plate are simultaneously bonded with the glass; the requirement for complex profile design can be met, meanwhile, the problem that the bonding strength of a low-temperature paint baseand glass is low is solved, low-temperature paint spraying of the outer plate can share a paint spraying and baking production line with common materials such as PP and ABS in the exterior decorationindustry, and the construction cost of the paint spraying and baking production line is saved.
本发明公开一种塑料后背门与玻璃粘接的工艺改进方法,先通过注塑成型法制造边缘设有框条的塑料后背门内板和外板,用遮蔽物遮蔽外板上的框条,对外板外表面喷涂低温油漆,低温油漆完全固化后移除遮蔽物;对位粘接内板和外板,内板和外板的框条随之拼接成与玻璃相吻合的粘接框;最后将玻璃粘接在粘接框上。本发明使外板、内板同时与玻璃粘接,不但能够满足复杂的型面设计要求,同时解决了低温油漆基底与玻璃粘接强度低的问题,外板低温油漆喷涂可以与外饰行业常用材料PP、ABS等制造零件共用油漆喷涂、烘烤生产线,节约了油漆喷涂、烘烤生产线的建设成本。
