Anti-static lining material and preparation method thereof

Abstract

An anti-static lining material comprises a medium-hardness layer, a low-hardness layer and a high-hardness layer, the low-hardness layer is located between the medium-hardness layer and the high-hardness layer, the medium-hardness layer, the low-hardness layer and the high-hardness layer are all anti-static thermoplastic elastomers, and the thickness ratio of the medium-hardness layer to the low-hardness layer to the high-hardness layer is 3:1:2 to 3:3:2. When the lining material is prepared, materials of three different-hardness layers are subjected to internal mixing, material crushing and component homogenizing and then are subjected to high-temperature melting, the high-hardness layer, the low-hardness layer and the medium-hardness layer need to be subjected to hot-press forming in sequence in the hot-press forming process, and the heat preservation temperature needs to be set in the hot-press forming process; and the molded lining material needs die cutting for removing edge materials with uneven texture and shaping. The lining material disclosed by the invention is designed according to transportation characteristics, effectively dredges and gathers charges, prevents the phenomena that electronic products are easy to displace and collide with one another under a bumpy transportation condition while having an anti-static property, and can be prevented from being damaged through effective buffering.

Description

technical field [0001] The invention relates to the technical field of coaming box material processing, in particular to an antistatic lining material and a preparation method thereof. Background technique [0002] For many electronic products, damage caused by static electricity needs to be considered during transportation. With the refinement and diversification of electronic products, the requirements for transportation are becoming more and more stringent, especially for expensive electronic products. The loading equipment requirements are higher. First of all, the packaging boxes used to carry electronic products generally include coaming boxes and pallets. The coaming boxes are provided with accommodating chambers for placing electronic products. However, due to collisions during transportation, in order to play a buffer role, it is necessary to Lining material is laid on the inner wall of the coaming box or the inner wall of the containing cavity. The lining materia...

Problems solved by technology

The lining material in the prior art has a good anti-static effect in an environment with high humidity, but during the transportation of electronic products, a dry environment is often required and even a dryer is placed to ensure the safe transportation of electronic products, but at the same time it is difficult to ensure the packaging The charge accumulated in the box can be effectively dredged; moreover, the inner lining is more likely to be in contact with the electronic product. If the inner lining is too soft, it will not be effective in fixing the position of the electronic product. If the inner lining is too hard, it will contact with the electronic product when it shakes. Rigid bump and friction
