Abstract

The invention discloses an antistatic master batch for a PP hollow sheet and a preparation method thereof. The antistatic master batch comprises components by the following weight parts: 70-90 parts of polypropylene powder, 3-9 parts of antistatic particles, 5-15 parts of antistatic powder, and 2-6 parts of plastic processing aid. During prepare, the polypropylene power and the antistatic particles are loaded into a high-speed mixing roll to obtain a blend; the antistatic powder and the plastic processing aid are loaded into the high-speed mixing roll to mix, and then a final blend is obtained; the final blend is loaded into a bidirectional screw extruder to extrude and granulate, and a strip-shaped blend is extruded, led into a water tank to be cooled, and then cut into an antistatic master batch by a cutter after cooling. After the antistatic master batch prepared by the method is used for the PP hollow sheet, the surface anti-resistance value of the hollow sheet can be reduced to 108-1011 ohm, the release time of the antistatic components on the surface is reduced to 1-3 days, the duration period of an antistatic effect is increased to 4-6 months, and the preparation method is simple and easy.

Description

Technical field [0001] The invention discloses an anti-static master batch for PP hollow boards, and the invention also discloses a preparation method of the anti-static master batches for PP hollow boards. Background technique [0002] PP hollow board is a thin board made of polypropylene as the main raw material and melted and extruded by an extruder. PP hollow board has been widely used in various industries because of its smooth surface, light weight, high strength and environmental protection. However, the PP hollow board has insulation properties, which greatly limits its application in electronic information packaging. When the ambient temperature is 25℃ and the humidity is 50%, the surface resistance value of ordinary PP hollow board reaches 10 13 ~10 14 Ω. In order to reduce the surface resistance of the hollow board, improve its electrical conductivity, and expand its application in electronic packaging, it is necessary to add antistatic masterbatch during the product...
