Abstract

The invention discloses a preparation method of a high-molecular material and particularly relates to a preparation method of a halogen-free flame-retarding anti-static polypropylene material. The main formula of the halogen-free flame-retarding anti-static polypropylene material comprises the following materials in parts by weight: 60-90 parts of polypropylene, 40-60 parts of a flame retardant, 2-6 parts of a flame-retarding additive, 5-10 parts of an anti-static agent, 0.05-1 part of an antioxidant and 10-20 parts of filler. The preparation method is characterized in that the anti-static property of the polypropylene material is improved by adopting graphene subjected to surface modification with a silane coupling agent as an anti-static agent. The preparation method disclosed by the invention has the advantages that on one hand, due to ultrahigh conductivity of the graphene, a good conductive channel can be formed in matrix resin by addition of a less amount of the graphene; on the other hand, the graphene subjected to surface modification with the silane coupling agent can be well dispersed in polypropylene, and further the bonding capability of the graphene and the interface of polypropylene is improved.

Description

technical field [0001] The invention relates to a polymer material, in particular to a preparation method of a halogen-free flame-retardant antistatic polypropylene material. Background technique [0002] Polypropylene is a thermoplastic with excellent performance, which has excellent processability, chemical resistance and mechanical strength. It is widely used in electronic appliances, aerospace, petrochemical, coal mine transportation and other application fields. [0003] Polypropylene products are divided into homopolymerization type and copolymerization type, and copolymerization type is divided into block copolymerization type and random copolymerization type. When the high fluidity homopolypropylene is impacted by low temperature, the toughness is poor, the molding shrinkage is large, and the parts are easy to warp and deform, but its fluidity is good, the tensile strength and bending strength are high; the high fluidity copolymer polypropylene improves the low tempe...
