透明抗静电电子载带片材及制备方法
摘要：
本发明公开一种透明抗静电电子载带片材，由中间层，抗静电上表层和抗静电下表层组成，其特征在于，所述中间层由以下质量百分比的成份组成：GPPS树脂46.5％?56.5％，MBS树脂35％?45％，MS树脂5％?15％，紫外线吸光剂0.1?0.5％，抗氧剂0.1?0.5％；所述抗电上表层由以下质量百分比的成份组成：GPPS树脂53.5％?63.5％，MBS树脂25％?35％，MS树脂5％?15％，PS抗静电母料2％?6％，紫外线吸光剂0.1％?0.5％，抗氧剂0.1％?0.5％；所述抗静电下表层与所述抗静电上表层的组成成份一致。本发明提供的透明抗静电电子载带片材具有韧性大、断裂延伸率高、透光性能好、无加工助剂析出的特点。本发明还提供一种透明抗静电电子载带片材的制备方法。
摘要（英）：

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.
