Abstract

The invention discloses a transparent antistatic resin composition for IC packaging tubes, which comprises the following components in parts by weight: 20-78 parts of methyl methacrylate-styrene resin, 20-78 parts of styrene-butadiene copolymer 1-5 parts and antistatic agent. The transparent antistatic IC packaging tube resin composition of the present invention adopts methyl methacrylate-styrene (MS) as matrix resin, and uses styrene-butadiene copolymer (SBC, also known as K glue) as toughening Toughening agent, it has a good rigidity-tough balance, adding antistatic agent, the obtained resin composition has better transparent effect and antistatic effect.

Description

technical field [0001] The invention relates to an IC packaging tube, in particular to a transparent antistatic IC packaging tube. Background technique [0002] The current production of IC (integrated circuit) packaging tubes is generally made of hard extrusion-grade PVC pellets (to produce PVC packaging tubes), extrusion-grade transparent HIPS pellets (to produce transparent PS packaging tubes), modified PET pellets ( Produce PET packaging tubes), PP and PE as raw materials. The production of IC packaging tubes in the market is dominated by PVC packaging tubes, accounting for 70% to 80% of the entire market. In recent years, in developed countries such as Europe, America, Japan and South Korea, IC packaging tubes are making rapid progress towards a more environmentally friendly and greener direction, especially the development momentum of transparent HIPS packaging tubes and PET packaging tubes. Transparent HIPS packaging tubes have good toughness and transparency, but t...
