Abstract
The invention relates to the technical field of thermoplastic engineering plastics, particularly to an alloy antistatic material for wafer trays, and a preparation method thereof, wherein the alloy antistatic material comprises, by weight, 30-50 parts of polyphenylene ether, 10-40 parts of high-impact-resistant polystyrene, 8-12 parts of electric-conduction carbon black, 3-6 parts of a styrene butadiene styrene block copolymer, 0.3-0.5 part of a silane coupling agent, 1-3 parts of a styrene-maleic anhydride copolymer, 8-12 parts of electric-conduction carbon black, 0.4-1 part of a lubricant, 3-4 parts of triphenyl phosphate, and 0.3-0.6 part of an antioxidant. According to the present invention, the alloy antistatic material has good mechanical property, and additionally achieves the permanent antistatic property of the PPO / HIPS alloy, such that the alloy antistatic material is safe in the packaging, testing and transportation of wafers.
Description
technical field [0001] The invention relates to the technical field of thermoplastic engineering plastics, in particular to an alloy antistatic material for a wafer tray and a preparation method thereof. Background technique [0002] Polyphenylene ether (PPO) material, as one of the five general-purpose engineering plastics in the world, is a thermoplastic engineering plastic with excellent performance. Unmodified polyphenylene ether resin has good mechanical properties, electrical properties, heat resistance, flame retardancy and chemical stability, etc. Therefore, polyphenylene ether is a widely used engineering plastic. However, polyphenylene ether has poor melt fluidity and is difficult to process. [0003] Through relevant research, it is found that ordinary polyphenylene ether and high-impact polystyrene (HIPS) alloys have outstanding electrical insulation properties. The excellent electrical properties of PPO / HIPS alloy make it widely used in the production of elect...
