The invention belongs to the field of composite materials and especially relates to a PC / PMMA material for a suitcase shell and a preparation method thereof. The PC / PMMA material for the suitcase shell is composed of polycarbonate, polymethyl methacrylate, sarin resin, flexibilizer, dispersing agent and antioxidant, wherein the mass ratio of polycarbonate to polymethyl methacrylate to sarin resinis at (2.8-14.5):(1.2-7):1. The PC / PMMA material provided by the invention has excellent scratching resistance and toughness and meets various test requirements for the suitcase shell material.
Description
technical field [0001] The invention belongs to the field of composite materials, in particular to a PC / PMMA material used for case shells and a preparation method thereof. Background technique [0002] Polycarbonate (PC) is widely used in luggage shells because it has excellent rigidity and good toughness at the same time, and has better scratch resistance than resins such as PA6, PBT, ABS, and PP. In order to increase the aesthetics of the case and bag, it is usually necessary to carry out film coating on the outside of the case. At the same time, the film coating can also reduce the scratches of the case and bag during use and prolong its service life. Methyl methacrylate (PMMA) is colorless and transparent, and has more than four times the scratch resistance of polycarbonate. At present, research has been based on the blending of PC and PMMA, aiming to combine the properties of these two polymers, especially the enhanced scratch resistance. [0003] However, the compat...
