High-wear-resistance transparent PC/PMMA alloy and preparation method thereof

The invention discloses a high-wear-resistance transparent PC/PMMA alloy, which is prepared from the following raw materials in parts by weight: 60 to 85 parts of PC resin, 10 to 35 parts of PMMA copolymer, 0.1 to 0.5 part of modified nano silicon dioxide and 1 to 3 parts of auxiliaries, the modified nano silicon dioxide is a SiO2-g-silane coupling agent-g-PMMA graft, has a core-shell structure, and comprises a core material, a silane coupling agent and a shell material which are sequentially coated from core to shell, the core material and the shell material are connected through the silane coupling agent, the core material is silicon dioxide nanoparticles, and the shell material is PMMA. The high-wear-resistance transparent PC/PMMA alloy provided by the invention does not contain any auxiliary agent or resin which is infusible or refractory with the alloy, and is excellent in wear resistance, high in transparency, good in mechanical property, simple, easy to process and wide in universality. 本发明公开了一种高耐磨透明PC
