Abstract

The invention relates to a permanent antistatic master batch and a preparation method thereof. The master batch comprises the following components in percentage by weight: 1-15 percent of alkali metal salt, 0.5-2 percent of antioxidant, 0.5-2 percent of heat stabilizer, 0-10 percent of assisting antistatic agent and 71-95 percent of polyether block-containing high polymer material. The preparation method comprises the following steps of: weighing raw materials according to the proportions, and putting into a high mixer for mixing for 2-5 minutes; discharging; and extruding and pelletizing with a double screw extruder to obtain the master batch, wherein the processing temperature is 150-200 DEG C, and the number of revolutions of a screw is 25-35 HZ. The invention further relates to a permanent antistatic composite material comprising the antistatic master batch and a preparation method thereof. The permanent antistatic master batch and the permanent antistatic composite material have the advantages of durable antistatic effect, permanent antistatic effect, various colors, low cost and high heat resistance.

Description

technical field [0001] The invention relates to a permanent antistatic masterbatch and a preparation method thereof, and also relates to a permanent antistatic PA6 composite material and a preparation method thereof. Background technique [0002] Nylon 6 (PA6) has good comprehensive mechanical properties, high heat resistance, good wear resistance, self-lubrication, good flame retardancy, excellent chemical corrosion resistance, excellent barrier properties and other properties Become the most widely used engineering plastics. However, PA6 has good electrical insulation like most polymer materials, and its surface resistivity is generally 10 13 -10 15 Ω·m, the conductivity is much smaller than that of metal materials. It is easy to accumulate static charge when it contacts or rubs with other substances. The negative effects brought by the accumulation of static electricity have seriously affected production, life, and work, and sometimes even cause fires and explosions. ...
