Abstract

The invention relates to an environmental-friendly polypropylene material with flame resistance and antistatic capacities, which comprises parts by weight of components that: 100pbw of pp resin, 30-50 portions of flame retardant, 10-20 portions of flame-retardant synergist, 40-60 portions of fillers and 10-30 portions of antistatic agent. The PP resin is high fluidity homopolymerization PP; the flame retardant is deca-diphenylethane; the flame-retardant synergist is antimony trioxide; the filler is 2000 meshes talcum powder; the antistatic agent is conductive carbon black; lubrication dispersing agent is aethylenum double fatty acid amide TAS-2A. The preparation method of the material is that: according to the part by weight, 100 portions of PP resin, 30-50 portions of flame retardant, 10-20 portions of flame-retardant synergist, 40-60 portions of fillers, 10-30 portions of antistatic agent and 1-10 portions of lubrication dispersant are weighted and mixed in a high-speed mixer for 3 to 5 minutes, and after mixing, the mixed raw materials are molten, squeezed and made into particles in a parallel twin-screw extruder. The polypropylene material of the invention has the advantages of good mechanical intensity, antistatic effect, flame resistance and being environment-friendly.

Description

[technical field] [0001] The invention relates to a polypropylene material, in particular to a polypropylene material with good mechanical strength, excellent antistatic effect, environmental protection and flame retardancy and a preparation method thereof. [Background technique] [0002] Polypropylene (PP) is one of the five general-purpose plastics with a density of 0.90g / cm 3 , is the second lightest polymer material in existing resins (only larger than polymethylpentene, with a density of 0.85g / cm 3 ). Because of its good performance, small specific gravity, and easy molding and processing, it is widely used in the automobile industry, household appliances, electronic instrument industry, and textile industry. [0003] As we all know, plastics have good electrical insulation properties, so they are widely used in various fields of industrial production and daily life. However, the high resistivity of the plastic surface often makes it easy to accumulate static electri...
