Problems solved by technology

However, 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, due to the high surface resistivity and volume resistivity of PP itself, the electrostatic charge generated cannot be transferred. When the surface electrostatic charge accumulates to a certain extent, it will bring serious dangers, such as dust collection, discharge, breakdown, Even burn or explode, which greatly limits the scope of use of PP, so that it can only be used in the field of insulation in industry or life

Abstract

The invention discloses a graphene oxide / zinc oxide antistatic polypropylene cast film and a preparation method thereof, and belongs to the technical field of materials. The graphene oxide / zinc oxideantistatic polypropylene cast film is prepared from, by weight, 100 parts of polypropylene resin and 5-15 parts of antistatic master batch, wherein the antistatic master batch is prepared from polypropylene resin, a composite antistatic agent OA / GO-g-ZnO and EVA resin. The composite antistatic agent OA / GO-g-ZnO used in the antistatic master batch combines the antistatic properties of graphene oxide and oleic acid, and zinc oxide uniformly grows on oleic acid functionalized modified graphene oxide to avoid agglomeration, so that the obtained polypropylene cast film has a good antistatic effect.

Description

technical field [0001] The invention belongs to the technical field of materials, and in particular relates to a graphene oxide / zinc oxide antistatic polypropylene casting film and a preparation method thereof. Background technique [0002] Polypropylene (PP) is a semi-crystalline polymer with high stiffness, excellent mechanical properties, good heat resistance and chemical resistance. It is also non-toxic, easy to recycle, and environmentally friendly. So in recent years, it has been widely concerned by researchers at home and abroad. However, 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, due to the high surface resistivity and volume resistivity of PP itself, the electrostatic charge generated cannot be transferred. When the surface electrostatic charge accumulates to a certain extent, it will bring serious dangers, such as dust collection, discharge, breakdown, Even burn or explode,...
