Problems solved by technology

Although products with higher transparency can be prepared, such antistatic agents rely on absorbing moisture in the air to achieve antistatic effects, and are easy to precipitate to make the surface worse, and are easy to be thermally decomposed during processing, so the dependence on humidity is too large
This type of antistatic agent loses its antistatic performance in an environment with a relative humidity of ≤40%RH, and the surface resistivity of the material is ≥10 12 Ω / sq, become an insulator, its antistatic performance is extremely unstable, and it cannot withstand washing or long-term use, and cannot meet the long-term requirements

Abstract

The invention relates to an antistatic plastics sheet, in particular to an antistatic polystyrene combination, a preparation method thereof and the produced sheet prepared by the combination. The antistatic polystyrene combination is made through mixing the components of the following prescription according to weight proportion: 65.0 percent to 85.0 percent of HIPS polystyrene, 8.0 percent to 28.0 percent of methyl-acrylic acid polyethylene glycol single methyl ether ester, 3.14 percent to 6.87 percent of hydroxylethyl methacrylate, 1.72 percent to 3.97 percent of sodium perchlorate, 0.0963 percent to 0.145 percent of azobisisobutyronitrile and 0.92 percent to 2.4 percent of coupling agent. In addition, the invention discloses a sheet that is produced by three layers of materials compounded together, wherein, the materials of the upper layer and the lower layer are the antistatic polystyrene combination gained through mixing the components. The antistatic polystyrene sheet of the invention saves the consumption of the antistatic polystyrene combination, reduces cost, adopts three surface layers combination with the property of no drop-off, is characterized by lasting long effect and low humidity sensitivity and enhances level and advancement of electric products packaging.

Description

technical field [0001] The invention relates to an antistatic plastic sheet, in particular to an antistatic polystyrene composition, a preparation method thereof and a sheet prepared from the composition. Background technique [0002] At present, polystyrene plastic products are widely used in the packaging and transportation of electronic products, but the surface resistance of ordinary plastics is greater than 10 12 More than Ω / sq, the conductivity is extremely poor, and static electricity is easily generated during the packaging and transportation of electronic products and is not easy to conduct away, causing great harm to electronic products. Therefore, it is imperative to develop and produce modified antistatic plastics. The surface resistivity of ordinary antistatic polystyrene plastics produced at present is mostly in the range of 10 9 -10 11 Ω / sq, although it has a certain antistatic performance, it can meet the needs of low-end electronic products with low electr...
