Problems solved by technology

[0003] The existing antistatic technology is mainly to apply an antistatic agent on the surface of the material, so that the packaging film has a certain conductivity, but because the antistatic agent is mostly surface active agent, can be free on the surface of objects, and is easy to interact with some substances in the air, thereby affecting the antistatic performance

Abstract

The invention discloses an anti-static packaging material and a preparation method thereof. The material is prepared from the following components in parts by weight: 50-75 parts of bisphenol A-type polycarbonate, 15-25 parts of isopropanol, 15-20 parts of phthalic acid dibutyl ester, 5-8 parts of graphene, 3-8 parts of hydrogenation soybean oil, 1-3 parts of antioxidant and 0.5-1 part of magnesium chloride. The preparation method comprises the following steps: adding the components into a high-speed mixing machine for commixing for 10 minutes at 110-120 DEG C, so as to obtain a commixed material, adding the commixed material into a double-screw extruder, performing melt extrusion by virtue of the double-screw extruder, subsequently cooling gradually, sequentially controlling the cooling temperatures to be 180 DEG C, 150 DEG C and 110 DEG C, performing air cooling and slicing into grains, thereby obtaining the anti-static packaging material. The anti-static packaging material disclosed by the invention has a good anti-static effect, and the preparation method is simple and low in cost.

Description

technical field [0001] The invention belongs to the field of functional materials, in particular to an antistatic packaging material and a preparation method thereof. Background technique [0002] The application of packaging materials in daily life and industrial production is very common. Various industries have different requirements for packaging materials, especially in the packaging of electronic devices and organic flammables. These products are very sensitive to static electricity. Sensitive, organic combustibles are prone to fire and other safety hazards under the condition of static electricity; electronic devices need to be transported and stored under non-static conditions, otherwise the accuracy and quality of the device will be affected. [0003] The existing antistatic technology is mainly to apply an antistatic agent on the surface of the material, so that the packaging film has a certain conductivity, but because the antistatic agent is mostly a surfactant...
