Description

Permanent antistatic polyolefin material and application thereof
Technical Field
The invention belongs to the field of polyolefin materials, and particularly relates to a permanent antistatic polyolefin material and application thereof.
Background
Polypropylene (PP) is a typical crystalline polymer, has the advantages of high heat resistance, good corrosion resistance, low density, light weight, excellent mechanical property, heat resistance, electrical insulation and the like, and is widely applied to injection molding parts, fibers, biaxially oriented films, pipes and the like. Because the polypropylene has strong electrical insulation, the surface resistivity of the polypropylene material is 10 15 ～10 18 Between Ω, therefore, static charge accumulation often occurs in the polypropylene products during production and use, and the static charge accumulation is easy to accumulate static to adsorb dust, and also causes accidents or hazards, so that the static electricity of polypropylene is eliminated, and the resistivity is required to be reduced.
The prior method for solving the antistatic problem on the surface of the polypropylene material mainly comprises the following steps: 1) The surfactant antistatic agent is added, and an antistatic layer is formed on the surface of the material through the rapid migration and water absorption of the surfactant, but the method is greatly affected by the environment, so that the antistatic performance of the material is very unstable; 2) Conductive materials such as conductive carbon black and metal powder are added, and the application range of the method is limited due to the limitation of the color of the conductive materials; 3) The polymer permanent antistatic agent is added to form a percolation network with electric conductivity inside the material, but the addition amount of the polymer permanent antistatic agent is large, which affects the performance of the material and is expensive.
CN104371279a discloses a composite material containing graphene, a preparation method and application thereof, the components of the composite material include a composite functional material with double conductive channels and a polymer matrix, and the composite functional material with double conductive channels is sulfonated graphene surface grafted conductive polymer poly 3,4- (ethylenedioxythiophene). Through the synergistic interaction between graphene and grafted poly 3,4- (ethylenedioxythiophene), the composite functional material has excellent antistatic performance. However, the modified polypropylene material is used for antistatic property of the modified polypropylene material, and a relatively large amount (up to 20% of the added amount is required to be added) of the composite functional material with double conductive channels is usually required to be added so as to ensure that the polypropylene can keep relatively good antistatic property. Therefore, the preparation of the conductive agent with small addition amount for modifying the antistatic property of the polypropylene has certain market value.
