Abstract

The invention belongs to the technical field of high polymer materials, and relates to a halogen-free flame retardant antistatic reinforcing modified polypropylene material and a preparation method thereof. The modified polypropylene material is prepared by the following components, by weight, 16-71.5 parts of polypropylene resins, 5-20 parts of glass fibers, 5-15 parts of ammonium polyphosphates, 2-5 parts of pentaerythritols, 10-15 parts of FR-MP, 1-4 parts of montmorillonoid, 3-8 parts of compatilizers, 2-15 parts of anti-static packing, 0.2-1 part of antioxygen and 0.3-1 part of lubricating agent. According to the halogen-free flame retardant antistatic reinforcing modified polypropylene material, expansive type flame retardant agents with reasonable compounded proportion can form a continuous coal layer under the condition of glass fibers to achieve excellent flame retardant performance, and the halogen-free flame retardant antistatic reinforcing modified polypropylene material has the advantages of being high in strength, obvious in antistatic effects and the like.

Description

Technical field [0001] The invention belongs to the technical field of polymer materials, and relates to a modified polypropylene material and a preparation method thereof. Background technique [0002] As a general plastic widely used in various fields of daily life production, polypropylene has good electrical insulation and high surface resistivity. These properties make polypropylene materials prone to static electricity accumulation during use, which can cause dust collection and spark discharge lamps. At the same time, because polypropylene has a limiting oxygen index value of only 18, it is a flammable material. The intumescent flame retardant compounded with a reasonable ratio in the present invention can also form a continuous carbon layer in the presence of glass fibers to achieve the advantages of excellent flame retardancy, high strength, and obvious antistatic effect. Summary of the invention [0003] The present invention provides a halogen-free flame-retardant ant...
