Abstract

The invention discloses a PC / PMMA alloy material. The invention relates to the technical field of polymer materials, and specifically relates to a PC / PMMA alloy material that improves surface hardness while achieving high-gloss black and eliminating pearlescent color. The main points of the technical scheme are as follows , calculated in parts by mass, including the following components: 65~75 parts of PC, 10~20 parts of PMMA, 1~5 parts of toughening agent, 1~3 parts of nano zirconia, 1 part of surface hardness modifier, antioxidant 0.1-1 part of anti-corrosion agent, 0.1-1 part of weather-resistant agent, and 0.1-2 parts of black dye. The purpose of the present invention is to provide a PC / PMMA alloy material with high gloss black, high hardness and weather resistance, which has industrial value.

Description

technical field [0001] The invention relates to the technical field of polymer materials, in particular to a PC / PMMA alloy material and a preparation method thereof. Background technique [0002] Polycarbonate (Polycarbonate, PC) is an amorphous thermoplastic engineering plastic with excellent performance. Polycarbonate is colorless and transparent, has good heat resistance, impact resistance, and good dimensional stability. It has good mechanical properties at normal operating temperatures. . However, unmodified polycarbonate still has shortcomings, such as insufficient processing fluidity, poor stress crack resistance, poor chemical resistance, poor wear resistance, and inability to balance surface hardness and toughness. [0003] Polymethylmethacrylate (PMMA) blended with PC can improve the friction resistance of PC, improve surface hardness, solvent resistance and processing performance, etc. At the same time, if the ratio of PC / PMMA alloy is not well controlled, it wil...
