Abstract

The invention discloses a high-glowing filament scratch-resistant PC material suitable for a tablet computer shell and a preparation method thereof. The material is prepared from, by weight, 65-70% of PC, 10-14% of flame retardant, 10-18% of scratch-resistant agent, 4-6% of toughening agent, 0.4-0.6% of anti-dripping agent, 0.1-0.2% of primary antioxidant, 0.3-0.4% of auxiliary antioxidant, 0.5-0.6% of lubricating agent and 0.3-0.5% of weather-proof agent. Engineering plastic PC is used as a main material, the halogen-free flame retardant, the toughening agent, the scratch-resistant agent, anti-dripping agent, the antioxidants, the weather-proof agent and the lubricating agent are added, all the materials are subjected to melt blending through a double-screw extruder, and the high-glowing filament scratch-resistant PC material suitable for the tablet computer shell is prepared. The material has the advantages of low price, low weight, scratch resistance, good weather fastness, halogen-free flame retardation, high-glowing filaments, excellent mechanical properties, high practicability and the like. Meanwhile, the preparation method of the material is simple and easy to implement and can be widely applied to industrial production.

Description

technical field [0001] The invention belongs to the field of polymer functional composite materials, and in particular relates to a high glow wire scratch-resistant PC material suitable for a tablet computer casing and a preparation method thereof. Background technique [0002] With the rapid development of network information technology, the use of tablet computers as smart terminals has increased year by year, and at the same time, higher requirements have been put forward for their performance and appearance. The lightness, thinness, miniaturization, low cost, and high security of tablet computers are the future development trends, and this is closely related to the shell materials used. [0003] Because PC / ABS has the characteristics of good processing performance and low cost, PC / ABS alloys are mostly used in the existing commercial tablet computer shells, but from the patent literature checked, the research on scratch resistance and glow wire performance is less Less ...
