At present, the antistatic technology of PVC is more, and in the prior art, antistatic PVC is provided, and alkyl sulfonate, heavy calcium carbonate and conductive fiber are added into the material to improve the antistatic capability. And the antistatic PVC has the antistatic effect of the reinforced buckle plate added with the octadecyl diethanol amine, so that the effects of difficult dust absorption and easy cleaning on the surface are achieved. However, the long-term antistatic performance of the PVC material is less, and the long-term antistatic performance of the PVC material is not a good enough PVC composition formula.

The average particle size of the ASA resin mainly influences the distribution state of the three antistatic agents, and when the average particle size of the ASA resin is 30-50 nm, the distribution of the antistatic agents can reach the optimal state.
The stabilizer is a composite lead stabilizer or a calcium-zinc stabilizer.
The average polymerization degree of the emulsion PVC resin is 900.
The sepiolite is sepiolite fiber, sepiolite velvet or sepiolite powder. The sepiolite is added with sepiolite fibers, sepiolite velvet or sepiolite powder, so that the internal ion concentration of the polymer can be better improved, and the osmotic pressure of the inner surface and the outer surface of the plate can be increased.
Preferably, the sepiolite is sepiolite powder. The sepiolite powder is easier to be evenly dispersed in the material, and the formed static conductive network from the inside to the surface of the plate is more compact and stable, so that the antistatic effect of the plate is better.
The sepiolite powder is micro sepiolite powder with the grain size of 1250 meshes.
The surface of the sepiolite powder is attached with a silane coupling agent. Drying the sepiolite powder in a blast dryer at the temperature of 90 ℃ for 12 hours, stirring the dried micro sepiolite powder in a high-speed stirrer at the rotating speed of 800-1200 r/min, and uniformly spraying silane coupling agent diluent on the surface of the stirred micro sepiolite powder.
The silane coupling agent is 3-aminopropyl triethoxysilane coupling agent with sepiolite weight of 1.8-2.2%. Silane coupling agent is prepared into silane coupling agent diluent which is evenly sprayed on the surface of the fine sepiolite in stirring. The silane coupling agent diluent is prepared by diluting 3-aminopropyl triethoxy silane coupling agent with the weight of 2 percent of sepiolite by ethanol. The fine sepiolite powder has the best dispersion effect after surface activation treatment by using the silane coupling agent.
Compared with the prior art, the antistatic PVC plate composition has the beneficial effects that the base resin for producing the antistatic PVC plate is prepared from emulsion PVC resin and ASA resin, so that the plate is endowed with enough strength and toughness, and the antistatic property of the plate is improved, three antistatic agents which are compounded are added into the base resin, wherein sorbitol powder and stearamidopropyl dimethyl- β -hydroxyethyl ammonium dihydrogen phosphate composite antistatic agent has an antistatic synergistic effect, the sorbitol powder and stearamidopropyl dimethyl- β -hydroxyethyl ammonium dihydrogen phosphate composite antistatic agent can continuously migrate from the interior of the material to the surface to play a role in moisture absorption and antistatic, sepiolite not only plays a role in delaying migration of stearamidopropyl dimethyl- β -hydroxyethyl ammonium dihydrogen phosphate to the surface of the plate and prolonging the moisture absorption and antistatic effects of the surface, but also can improve the ion concentration in the polymer, increase the osmotic pressure of the inner surface and the outer surface of the plate, accelerate the water on the outer surface of the plate to enter the interior of the plate to form a static conduction network from the interior of the plate to the interior of the plate, so that the antistatic effect is better, the sorbitol powder, β -dimethyl-propyl ammonium dihydrogen phosphate and the antistatic agent play a role in compounding and the antistatic effect from the plate to the three antistatic agent to the three antistatic effect of the antistatic sepiolite for a long-synergistic effect.
