Abstract

The invention relates to a permanently antistatic masterbatch and a preparation method. The masterbatch comprises the following components in percentage by weight: 1-15% of alkaline metal salt, 0.1-2% of antioxidant, 0.1-2% of heat stabilizer, 0-10% of assistant antistatic agent, and 70-95% of high polymer material with polyether blocks. The invention also relates to permanently antistatic PA6 / PA66 (Polymide 6 / Polymide 66) alloy, which comprises the following components in percentage by weight: 3-8% of anti-static masterbatch, 40-45% of PA6, 40-50% of PA66 and 1-5% of compatilizer. The permanently antistatic masterbatch is prepared by the following steps of: mixing the components; extruding; pelleting; and obtaining the product. The surface resistivity of the masterbatch can reach 102-103ohm m, and the surface resistivity of the PA6 / PA66 alloy can reach 106-108 ohm m. The invention has the advantages that the antistatic effect is lasting, the permanently antistatic effect is achieved, the antistatic effect is good, the comprehensive mechanical property is higher, the color is light and can be prepared into various colors, the cost is low, and the heat resistance is good.

Description

technical field [0001] The invention relates to a permanent antistatic master batch and a preparation method thereof, and also relates to a preparation method of a permanent antistatic PA6 / PA66 alloy. Background technique [0002] Because nylon has good comprehensive mechanical properties, high heat resistance, good wear resistance, self-lubricating properties, good flame retardancy, excellent chemical corrosion resistance, excellent barrier properties and other properties, it has become the most suitable for current applications. Wide range of engineering plastics. But nylon, like most polymer materials, has good electrical insulation, and its surface resistivity is generally around 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, ...
