Composite PETG material

The invention discloses a composite PETG material, and belongs to the technical field of macromolecules. The composition comprises PETG (polyethylene terephthalate glycol), PTMEG (polytetramethylene ether glycol), PMMA (polymethyl methacrylate), maleic anhydride grafted polypropylene, phenethyl alcohol, glass beads, pearlescent mica, a hindered phenol antioxidant and a dispersing agent. According to the invention, PMMA and PETG are used as main materials, and the transparent composite PETG material with good comprehensive performance is obtained through specially selected auxiliary materials, and can be applied to a plurality of different fields. According to the preparation method, existing equipment does not need to be greatly transformed, only parameters need to be adjusted, and the transformation difficulty is low. 本发明公开了一种复合PETG材料，属于高分子技术领域。其组分PETG、PTMEG、PMMA、马来酸酐接枝聚丙烯、苯乙醇、玻璃微珠、珠光云母、受阻酚类抗氧剂、分散剂。本发明以PMMA和PETG作为主体材料，通过特选的辅料获得一种具有良好综合性能的透明符合PETG材料，能够应用于多个不同领域中。本发明的制备方法无需对现有设备进行大改造，只需要调节参数即可，改造难度低。
