Abstract

The invention relates to the technical field of packaging material preparation, in particular to a preparation method of an EPE environment-friendly packaging material. The EPE environment-friendly packaging material is prepared from the following raw materials in parts by weight: 90 to 110 parts of modified low-density polyethylene, 1.8 to 2.5 parts of 2-(2 '-hydroxy-5'-methylphenyl) benzotriazole, 3.2 to 4.0 parts of azodicarbonamide, 2.2 to 2.7 parts of glyceryl monostearate, 1.6 to 2.4 parts of polyethylene wax, 2.5 to 3.5 parts of nano titanium dioxide, 1.5 to 2.0 parts of talcum powder and 2.0 to 2.5 parts of a surfactant. The antistatic additive, the modified sepiolite powder, the maleic anhydride grafted POE and other raw materials are used for performing melt blending on the low-density polyethylene, and the antibacterial property and the antibacterial durability of the EPE packaging material are effectively improved through the synergistic cooperation between the modified sepiolite powder and the nano titanium dioxide; the antistatic additive, glyceryl monostearate and polyethylene wax cooperate with one another to effectively improve the antistatic performance of the prepared EPE packaging material, and the quality of the EPE packaging material is effectively improved.

Description

technical field [0001] The invention relates to the technical field of packaging material preparation, in particular to a preparation method of EPE environment-friendly packaging material. Background technique [0002] EPE is expandable polyethylene, also known as pearl cotton, which is a non-crosslinked closed-cell structure. It is composed of low-density polyethylene fat through physical foaming to produce countless independent bubbles. It is a relatively advanced protective inner packaging material in the world. EPE has high elasticity and white appearance. Because it is a completely independent cell body, it is light, flexible, and can be bent to absorb the impact force, disperse it, and have a cushioning effect, which overcomes the shortcomings of ordinary foam rubber such as fragility, deformation and recovery. EPE has heat preservation, water and moisture resistance, Heat insulation, sound insulation, anti-friction, anti-aging, corrosion resistance and other charac...
