Problems solved by technology

[0003] Most of the existing transparent antistatic electronic carrier sheets are made of PS resin (polystyrene resin), ABS resin (acrylonitrile-butadiene-styrene copolymer), K resin (butadiene transparent impact-resistant resin) Several of them are used as the main material, and there are problems of insufficient mechanical strength and transparency (the general light transmittance is lower than 83%).
Especially for some high-speed molding and high-speed packaging processes, its mechanical strength needs to be further improved

Abstract

The invention discloses a transparent anti-static electronic carrier tape sheet which is composed of a middle layer, an anti-static upper surface layer and an anti-static lower surface layer.The transparent anti-static electronic carrier tape sheet is characterized in that the middle layer is prepared from, by mass, 46.5%-56.5% of GPPS resin, 35%-45% of MBS resin, 5%-15% of MS resin, 0.1%-0.5% of ultraviolet light absorption agent and 0.1%-0.5% of antioxidant; the anti-static upper surface layer is prepared from, by mass, 53.5%-63.5% of GPPS resin, 25%-35% of MBS resin, 5%-15% of MS resin, 2%-6% of PS anti-static master batches, 0.1%-0.5% of ultraviolet light absorption agent and 0.1%-0.5% of antioxidant; the components of the anti-static lower surface layer are the same as those of the anti-static upper surface layer.The transparent anti-static electronic carrier tape sheet has the advantages of being high in toughness, high in elongation at break, good in light transmittance performance and free of processing agent precipitation.The invention further provides a preparation method of the transparent anti-static electronic carrier tape sheet.

Description

technical field [0001] The invention relates to a composite sheet and a processing method thereof, in particular to a transparent antistatic electronic tape-carrying sheet and a preparation method thereof. Background technique [0002] Carrier tape is a strip-shaped product used in the field of electronic packaging, which needs to have certain strength and toughness. With the precision and miniaturization of electronic components, the carrier tape materials for electronic packaging are becoming narrower; correspondingly, this also requires the carrier tape materials to have more excellent toughness, elongation at break and light transmission properties. To ensure sufficient tensile strength and to clearly identify the contents of the package. [0003] Most of the existing transparent antistatic electronic carrier sheets are made of PS resin (polystyrene resin), ABS resin (acrylonitrile-butadiene-styrene copolymer), K resin (butadiene transparent impact-resistant resin) Sev...
