Example Embodiment

[0030] In the following, the present invention will be further described in detail with reference to the embodiments:

[0031] In the composite material formulations of the Examples and Comparative Examples, the polypropylene is a block co-polypropylene produced by Shanghai Petrochemical, the trade name is M700R, and its melt index is 11g / 10min (test conditions: 230°C×2.16kg). The talc powder produced by Haicheng has a particle size of 10 microns. The toughening agent POE is a linear ethylene-octene copolymer produced by DuPont, the trade name is 8180, and its density is 0.88~0.90g / cm 3 , The melt index is 0.5g / 10min (test condition: 190℃×2.16kg). The antistatic agent is SnO with a particle size of 0.5-3μm 2 . The main antioxidant is DSTP produced by British ICE company, the trade name is Negonox DSTP, the chemical name is stearyl thiodipropionate, and the 3114 produced by Ciba company, the trade name is Irganox 3114, and the chemical name is 3. , 5-Di-tert-butyl-4-hydroxybenzy...

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...
