Description

technical field [0001] The invention relates to the technical field of plastic masterbatch preparation, in particular to a graphene conductive masterbatch and its preparation method and application. Background technique [0002] At present, polymer materials have been widely used in many fields such as national defense, military industry, and electronic products. However, most polymer materials have high volume resistivity. Due to the high resistivity of polymer materials, static electricity is not easy to remove, resulting in a large accumulated voltage, which has a great negative impact on the production and use of plastic products. For example, static electricity will cause dust in the air to adsorb on the product, affecting its appearance and reducing its commercial value. Another example is that static electricity will cause ink or fuel to adhere unevenly and fall off easily when the product is printed. Another example is static electricity will produce discharge phenom...
