Embodiment 1

[0018] A calcium sulfate antistatic floor base material, which is prepared from the following raw materials:

[0019] Calcium sulfate, paper fiber, zeolite powder, perlite, sepiolite, lignocellulose, fly ash, peanut shell, soybean meal, brucite fiber, polypropylene fiber, carboxymethyl cellulose, diatomaceous earth, zinc borate ,water;

[0020] The preparation technology of above-mentioned floor substrate comprises the steps:

[0021] 1) Put calcium sulfate, paper fiber, lignocellulose and fly ash into the high-speed mixer according to the mass ratio of 10:3:1:1, stir at 1000rpm for 10-15min, and raise the temperature at 10℃ / min at the same time. When the temperature rises to 90°C, stop heating, and naturally cool to room temperature, which is the mixture A;
