Problems solved by technology

Due to the high surface resistivity and volume resistivity of PP itself, it is impossible to transfer the generated static charge. When the surface static charge accumulates to a certain extent, it will absorb dust, which not only affects the appearance of the material, but also easily causes dust suction electric shock. Or spark discharge and other undesirable phenomena are not conducive to the processing and use of plastic products. The antistatic problem of plastics has attracted people's great attention.
[0004] Polypropylene is extremely flammable and cannot meet the needs of specific fire protection areas

Abstract

The invention discloses a flame-retardant and reinforced antistatic PP composite material and a preparation method thereof, wherein the Flame-retardant and reinforced antistatic PP composite material comprises the following formula components: polypropylene, a compatilizer, a white mineral oil, a coupling agent, glass fiber, a flame retardant, a synergetic flame retardant, an antistatic agent, a composite lubricant, and other auxiliary agents. The flame-retardant and reinforced antistatic PP composite material uses polypropylene as a matrix resin, uses a self-prepared compatilizer matched to the coupling agent, so as to make excellent combination force exist between the antistatic agent and the glass fiber, and the matrix resin, overcome a wick effect of the glass fiber-reinforced and flame retardant material, and have good flame retardant. Simultaneously, the glass fiber and conductive carbon black have obvious conductive synergism, so as to make the material have excellent conductivity. The preparation has advantages of simple operation, low cost and high production benefit, and is suitable for industrialization production.

Description

technical field [0001] The invention relates to the technical field of polymer materials, in particular to a fire-retardant reinforced antistatic PP composite material and a preparation method thereof. Background technique [0002] As one of the five general-purpose plastics, polypropylene is widely used in the automotive industry, household appliances, electronic components and other industries due to its low density, high cost performance, and easy molding and processing. [0003] However, polypropylene (referred to as PP) is a highly insulating material, and its volume resistivity is generally 10. 16 ~10 18 Ω·m, surface resistivity 10 16 ~10 17 Ω·m, the surface will generate electrostatic charges under the process of friction, peeling or induction. Due to the high surface resistivity and volume resistivity of PP itself, it is impossible to transfer the generated static charge. When the surface static charge accumulates to a certain extent, it will absorb dust, which n...
