Problems solved by technology
However, unmodified polycarbonate still has many shortcomings, such as poor processing fluidity, low temperature impact toughness, flame retardancy and stress crack resistance, etc. Therefore, in practical applications, it is usually necessary to modify PC
[0003] In order to improve processability, PC can be compounded with resin with good fluidity, such as adding ABS resin with good fluidity, which can improve the impact resistance and processability of PC at the same time, but it is still insufficient in terms of strength and flame retardancy
In addition, the high cost of PC limits its further application. Although the PC recycled material in the prior art reduces the material cost, it loses the performance advantage of PC after repeated thermal processing.

Abstract
The invention discloses a halogen-free flame-retardant porcelain-white polycarbonate composite material with high glossiness. The composite material comprises following raw materials in parts by weight: 85 to 95 parts of polycarbonate, 0.4 to 1 part of halogen-free flame retardant, 1 to 5 parts of flexibilizer, 0.5 to 1 part of antioxidant, 0.2 to 0.6 part of flowing agent, and 2 to 8 parts of titanium dioxide. A flexibilizer is compounded with a halogen-free flame retardant with high fluidity and a flowing agent; the fluidity of the melt is good, the moulding efficiency and surface glossinessare high; the mechanical performance, flame retardant performance, and electrical properties are excellent; and the problems of cracking caused by stress and pits in the surface are solved effectively.
Description
technical field [0001] The invention belongs to the field of polymer composite materials, and in particular relates to a halogen-free flame-retardant high-gloss porcelain white polycarbonate composite material. Background technique [0002] Polycarbonate (PC) has excellent impact resistance, heat resistance, electrical insulation and weather resistance, and is widely used in electronic appliances, automobiles, machinery, construction engineering, daily necessities and other fields. However, unmodified polycarbonate still has many shortcomings, such as poor processing fluidity, low temperature impact toughness, flame retardancy and stress crack resistance, etc. Therefore, in practical applications, it is usually necessary to modify PC . [0003] In order to improve processability, PC can be compounded with resin with good fluidity, such as adding ABS resin with good fluidity, which can improve the impact resistance and processability of PC at the same time, but it is still i...
