Packaging material with antistatic and antibacterial properties and preparation method of packaging material

Abstract

The invention discloses a packaging material with antistatic and antibacterial properties. The packaging material is prepared from the following raw materials in parts by weight: 50-70 parts of low-density polyethylene resin, 10-30 parts of linear polyethylene resin, 6-8 parts of stearate, 5-10 parts of glass fiber, 1-3 parts of thermoplastic plastic, 3-5 parts of 20% calcium carbonate masterbatch, 2-5 parts of an antistatic agent, 1-3 parts of a lubricant, 3-6 parts of zinc oxide whisker, 4-8 parts of graphene and 1-5 parts of two kinds of low molecular weight chitosan. According to the packaging material disclosed by the invention, chitosan instead of nano silver is adopted as an antibacterial raw material, and the cost can be remarkably reduced; by adding graphene which is a special-structure conductive material, a better effect of promoting the antistatic property is realized; the zinc oxide whisker with a four-leg three-dimensional structure is added; when zinc oxide is dispersed in a matrix, adjacent needle-shaped parts are in mutual lap joint to form a conductive path which cooperates with the permanent antistatic agent to efficiently give antistatic property to the material; and meanwhile, since calcium carbonate masterbatch is added as a degrading component, the degradation property of the packaging material is good.

Description

technical field [0001] The invention relates to a polymer material and a preparation method thereof, in particular to a packaging material with antistatic and antibacterial properties and a preparation method thereof. Background technique [0002] The application of packaging materials in daily life and industrial production is very common. Each industry has different requirements for packaging materials, especially in the packaging of electronic devices and the packaging of organic flammable materials. These products are very sensitive to static electricity. , 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 condu...
