Oil-free antistatic pearl cotton

Abstract

The invention relates to oil-free antistatic pearl cotton prepared by foaming the following materials by mass: 75%-85% of high pressure polyethylene, 3%-10% of degreased masterbatch and 3%-10% of antistatic masterbatch; in the making process, butane gas with the mass ratio of 8%-12% is introduced for foaming. The oil-free antistatic pearl cotton prepared from the materials does not appear the phenomenon of infiltration of grease in the late use, and may not pollute parts; by the use of the antistatic masterbatch, the prepared oil-free antistatic pearl cotton has good antistatic effect, may not absorb dust and fine particles, and can ensure the parts are not polluted by dust, the oil-free antistatic pearl cotton can be prepared into foam packing bags by post processing, and the foam packing bags are used to package some electronic products such as TV, mobile phones, LCD panels and the like, ensures that the surface of the electronic product may not stick to grease and dust layer, and ensures the normal operation of electrical components of the electronic products.

Description

technical field [0001] The invention relates to the packaging material manufacturing industry, in particular to an oil-free and antistatic pearl cotton. Background technique [0002] Pearl cotton is a new type of environmentally friendly packaging material. It is composed of low-density polyethylene fat through physical foaming to produce countless independent bubbles. It overcomes the shortcomings of ordinary styrofoam that are fragile, deformed, and poor in recovery. It has many advantages such as water and moisture proof, shockproof, sound insulation, heat preservation, good plasticity, strong toughness, recycling, environmental protection, strong impact resistance, etc. It also has good chemical resistance and is an ideal substitute for traditional packaging materials. Wide application prospects. [0003] Traditional pearl cotton has high requirements on raw materials and high production cost, and ordinary pearl cotton will leak oil and easily contaminate the packagin...

AI Technical Summary

Problems solved by technology

[0003] Traditional pearl cotton has high requirements on raw materials and high production cost, and ordinary pearl cotton will leak oil and easily contaminate the packaging parts; some parts will generate static electricity during packaging, causing the parts to be damaged. Absorb dust, so that the parts that require dust-free packaging cannot be packaged, and the market's requirements for oil-free and anti-static packaging materials cannot be met.

[0004] At present, in order to further reduce the packaging cost of electronic products during transportation, enterprises in the electronics field use foaming materials to replace the original pure plastic wrapping paper. Effective adsorption, resulting in a lot of grease and dust on the surface of electronic products, affecting the normal use of electronic products
