Antistatic polypropylene composite material and method for preparing same

Abstract

The invention discloses an antistatic polypropylene composite material and a method for preparing the same and belongs to the technical field of modifying and processing polymers. The antistatic polypropylene composite material is prepared from the following raw materials in percentage by weight: 50 to 98 percent of polypropylene, 0 to 30 percent of inorganic filler, 0 to 20 percent of flexibilizer POE, 1 to 5 percent of antistatic agent, 0.1 to 1 percent of antioxidant and 0 to 1 percent of other auxiliary agents. The composite material and the method have the advantages that: 1, a proper amount of tin oxide is added in the composite material system, so that the prepared polypropylene composite material has better antistatic property; 2, under a condition of guaranteeing the antistatic property, the physical mechanical properties of the prepared polypropylene composite material are hardly affected; and 3, the method for improving the antistatic property of the polypropylene composite material is simple in preparation process and low in production cost.

Description

technical field [0001] The invention relates to an antistatic polypropylene composite material and a preparation method thereof, more specifically, the antistatic performance of the polypropylene composite material is improved by adding an antistatic agent, which can be used in the fields of electronics, petrochemical industry, medical treatment, etc., and belongs to polymer modification and processing technologies. Background technique [0002] Polypropylene (PP) is a widely used general-purpose plastic because of its good processing properties, physical, mechanical, chemical properties and electrical insulation properties, as well as light weight and low price. However, good electrical insulation makes it prone to electrostatic hazards during use, thus limiting its application in electronics, petrochemical, medical and other fields. [0003] In order to reduce the volume resistivity of PP and eliminate static disasters, adding antistatic agents to PP base materials is the...

Problems solved by technology

Ordinary low molecular weight antistatic agents have poor durability, are not resistant to scrubbing, and are highly dependent on environmental humidity

Polymer permanent antistatic agent has a long-lasting antistatic effect, no induction period, and is not easily affected by conditions such as wiping and washing, but the addition amount is relatively large (generally 5%-20%), and the price is relatively high
