Non-electrostatic isolating plate

Abstract

An antistatic separate sheet is provided. The antistatic separate sheet comprises a polyolefin-based resin and a composition comprising a polymer resin essentially having both polyolefin-based skeleton and a hydrophilic polymer skeleton; and it has a surface inherent resistivity of 10 not 11 Ohm or less. A separate sheet of better performance can be acquired by mixing conductive fiber member into the composition, and it has a surface inherent resistivity of 10 not 7 Ohm or less.

Description

technical field [0001] The present invention relates to a partition board (also called a stacking board) used when containers are stacked in multiple layers on a pallet to unitize them. Background technique [0002] So far, metal containers for soft drinks, beer, edible oil, canned food, etc., glass containers for medical supplies, industrial chemicals, liquid flavorings, etc., or plastic containers for liquid detergents, flavorings, ice cream, etc., have been widely used in many fields. Various capacities. Moreover, almost all loading and unloading operations such as packaging and transportation of these containers have been mechanized or automated. [0003] As one of the above-mentioned packaging and transportation methods, there is a unit loading method. This method is a method of packing or transporting containers, etc., by combining them into a unit with an appropriate number or weight, making them integrated, and loading and unloading them with a machine without dism...

AI Technical Summary

Problems solved by technology

However, because cardboard absorbs water and moisture, its mechanical strength such as bending rigidity and impact resistance is low, and its repeated use is limited.

Moreover, because the raw material is paper, it is fluffed or damaged, and the pollution is serious, so it is restricted to be used in areas afraid of dust such as food and medical supplies due to unsanitary conditions.

[0006] As a separator that eliminates these problems, there are plastic separators, but the problem with plastic separators is that static electricity is severe and dust is easily generated.

[0013] However, the method of multi-layering the separator and adding conductive fibers only to the surface layer cannot be said to be the best method because the multi-layer board must be manufactured and the device is complicated.

In the method of mixing with a hydrophilic polymer, when the separator is made of ABS polymer, the antistatic performance can be realized due to the compatibility between the ABS polymer and the hydrophilic polymer, but the separator is made of polyolefin resin. At the time of manufacture, polyolefin resin is a hydrophobic polymer, and the compatibility with hydrophilic polymers is extremely poor

Therefore, even if the polyolefin resin and the hydrophilic polymer are mixed, it is difficult to obtain antistatic performance on the entire surface of the separator because the two are separated from each other during molding to form an island structure.
