Abstract

The invention discloses a sandwich panel containing oxide particle grafts and a manufacturing method thereof, comprising a PC layer and a PMMA layer, the PC layer is made of polycarbonate, and the PMMA layer is made of polymethylmethacrylate It also includes a melt-mixed layer, the melt-mixed layer is located between the PC layer and the PMMA layer, the PMMA layer is interspersed with oxide particle grafts, and the polycarbonate is silicon-oxygen-containing alkane block polycarbonate, the melt-mixed layer contains oxide particle grafted siloxane structure. The oxide particle grafted siloxane structure in the present invention is a highly cross-linked network structure, which not only ensures the binding force of the sandwich panel but also plays a buffering role, and at the same time the oxide particle graft has a strong impact on the sandwich panel. The surface layer plays a toughening role, making the surface layer more resistant to bursting when the product is hot stamped.

Description

technical field [0001] The invention relates to a sandwich panel, in particular to a sandwich panel containing oxide particle grafts and a manufacturing method thereof. Background technique [0002] At present, some manufacturers in the market have tried to combine PMMA with PC materials or other materials to form a new material with both high elasticity and high hardness. However, in the process of making multilayer boards, due to the characteristics of the two resins Due to the difference in functional groups, some functional groups at the end cannot form a network molecular structure. At the same time, due to the problems of large stress and strain and poor interface compatibility between the PC material and the PMMA material, it eventually leads to redundant composite components. The stress is manifested in the appearance that there are local concave-convex patterns and overall corner warping, which makes the finished double-layer composite board easy to delaminate and f...
