Abstract

The invention relates to a permanent antistatic master batch and a preparation method thereof. The antistatic 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, wherein the polyether block-containing high polymer material is a compound consisting of polyethylene glycol oxide and poly(ether ester amide) in the weight ratio 5:1. The preparation method comprises the following steps of: weighing raw materials according to the parts by weight, 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 PA6/PPO (Polyamide 6/Polyphenylene Oxide) alloy and a preparation method thereof. The antistatic master batch and the alloy provided by the invention 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 / PPO alloy and a preparation method thereof. Background technique [0002] Because 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. Polyphenylene ether (PPO) has the advantages of high rigidity, high heat resistance, good water resistance, flame retardant, high strength and excellent electrical properties. It also has the advantages of wear resistance, non-toxicity, and pollution resistance. Its dielectric constant and Dielectric loss is one of the smallest varieties among engineering plastics, almost not affected by temperature and humidity, and can be used in low, medium and high...
