PMMA alloy material and preparation method thereof

The invention discloses a PMMA alloy material and a preparation method thereof, and belongs to the technical field of polymer alloy materials. The product provided by the invention comprises the following components in parts by weight: 45-60 parts of PMMA resin, 20-35 parts of a toughening agent, 15-25 parts of a heat-resistant agent, 0.5-2 parts of aminated carbon nanotubes, 1-3 parts of color master batches and 0.5-2 parts of a processing aid. The heat-resistant agent is a styrene-maleic anhydride copolymer; the N element content of the aminated carbon nano tube is 0.3 to 1 weight percent. The product has an ideal high bright black effect and sufficient impact resistance, and meanwhile, the specific heat-resistant agent is matched with the special aminated carbon nanotubes, so that excellent heat resistance and a short forming period can be realized. 本发明公开了一种PMMA合金材料及其制备方法，属于高分子合金材料技术领域。本发明所述产品包括以下重量份的组分：PMMA树脂45～60份、增韧剂20～35份、耐热剂15～25份、氨基化碳纳米管0.5～2份、色母粒1～3份以及加工助剂0.5～2份；所述耐热剂为苯乙烯-马来酸酐共聚物；所述氨基化碳纳米管的N元素含量为0.3
