Abstract

The invention is applicable to the technical field of composite material manufacturing, and provides a novel mobile phone front cover composite board structure and a production process thereof, the novel mobile phone front cover composite board structure comprises a first PMMA layer 1 and a second PMMA layer 3, a PC layer 2 is arranged between the first PMMA layer 1 and the second PMMA layer 3, the thickness of the first PMMA layer 1 and the second PMMA layer 3 is 0.08-0.12 mm, and the thickness of the PC layer 2 is 0.7-0.8 mm. The first PMMA layer and the second PMMA layer are arranged, the PC layer is arranged between the first PMMA layer and the PMMA layer, the PMMA material belongs to high-temperature particles, the PC material belongs to low-temperature particles, and the PMMA material and the PC material are subjected to co-extrusion, hot bending and other technological processes to produce the novel composite board. The novel composite board is produced by selecting a novel combined material and a novel process, so that the yellowing phenomenon of the 3D cambered surface is effectively solved.

Description

technical field [0001] The invention belongs to the technical field of composite material production, and in particular relates to a novel mobile phone front cover composite plate structure and a production process thereof. Background technique [0002] Composite board mobile phone 3D screen cover is a newly developed TP screen cover project. It replaces the mobile phone glass screen with a composite board screen to achieve the purpose of screen resistance, low cost, high efficiency and high use. [0003] At present, the TP screen produced by conventional composite panels on the market has the phenomenon of yellowing of the 3D curved surface, which seriously affects the visual sense of users, and there is a phenomenon of eye fatigue, and the production efficiency is low. Contents of the invention [0004] The purpose of the present invention is to solve the problems of 3D curved surface yellowing and low production efficiency in the TP screen produced by conventional compo...
