Abstract

The invention relates to a novel antistatic polypropylene material, specifically, the antistatic polypropylene material consists of the following components in parts by weight: 100 parts of polypropylene, 5-10 parts of polymer conductive fiber, 1-5 parts of styrene series thermoplastic elastomer, 0.5-2 parts of trimethoxychlorosilane, 0.1-0.5 part of hydroquinone, 0.1-0.5 part of urea-formaldehyde resin and 0.5-2 parts of paraffin oil. A proper amount of polymer conductive fibers is used, so that the prepared antistatic polypropylene material has better antistatic properties; and the obtained antistatic polypropylene material ensures the antistatic property and at the same time ensures the physical, and mechanical properties are basically unaffected. A preparation method of the invention is simple in process, and low in costs, and the industrial production is easy to realize.

Description

technical field [0001] The invention belongs to the technical field of antistatic materials, and relates to a novel antistatic polypropylene material and a preparation method thereof. Background technique [0002] Polypropylene (PP) is a widely used general-purpose plastic due to its good physical, mechanical, chemical properties, processability and electrical insulation properties, as well as light weight and low price. However, the volume resistivity of polypropylene is in the range of 10 13 ~10 20 Within the range of Ω.cm, it is easy to generate electrostatic hazards during use, which limits its application in electronics, petrochemical, medical and other fields. [0003] In order to reduce the volume resistivity of PP, the most common measure is to add conductive materials to it. Commonly used conductive materials mainly include carbon black, graphite, etc. Carbon black is cheap and practical, and its surface resistance range can reach 10 2 ~10 9 Ω, but the added am...
