Abstract

The invention relates to a plastic tray material and a preparation method thereof, and relates to the technical field of plastic products. The plastic tray material comprises the following componentsby mass: 50-59.94% of conductive fiber modified PS resin, 25-29.9% of PS resin II, 15-20% of carbon black and 0.06-0.10% of an antioxidant. The preparation method of the plastic tray material specifically comprises the following steps: S1, carrying out crushing treatment on carbon black, then grinding the carbon black into powder, and carrying out drying treatment on the carbon black powder aftergrinding is completed; s2, carrying out premixing treatment on the carbon black powder and an antioxidant; s3, stirring and mixing the conductive fiber modified PS resin, the impact-resistant PS resinand the premix; s4, feeding the blended material in S3 into a screw extruder for blending and extrusion; and S5, cooling, granulating and screening the extruded material to obtain a plastic tray material, and packaging and warehousing the plastic tray material. The embodiment has the effect of improving the weak anti-static performance of the plastic tray.

Description

technical field [0001] The present application relates to the technical field of plastic products, in particular to a plastic pallet material and a preparation method thereof. Background technique [0002] Electronic products such as semiconductor chips or electronic components are usually integrated with multiple tiny circuit components, and are usually packaged in plastic trays during storage or transportation. At present, the packaging trays used in the industry for electronic products mainly include blister-molded plastic trays, including PE trays and ABS trays. The packaging tray needs to have good mechanical properties and high temperature resistance, that is, the tray does not deform under high temperature or external force. If the tray is required to have a high degree of cleanliness, it must also have good corrosion resistance. Since electronic products such as semiconductor chips or electronic components are very sensitive to static electricity, the antistatic per...
