Abstract
The invention discloses a permanent antistatic PA66 / POE (Polyamide 66 / Polyolefin Elastomer) alloy and a preparation method thereof. The alloy comprises the following components in percentage by weight: 3-8 percent of antistatic master batch, 40-75 percent of PA66, 15-25 percent of POE and 1-5 percent of compatilizer. The antistatic master batch comprises the following components in percentage by weight: 1-15 percent of alkali metal salt, 0.1-2 percent of antioxidant, 0.1-2 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 mixing; discharging; and extruding and pelletizing. The permanent antistatic PA66 / POE ally has the advantages of durable antistatic effect, permanent antistatic effect, good antistatic effect, high comprehensive mechanical property, performance which is approximate to that of a pure PA66 / POE alloy, various colors, low cost, high heat resistance, and the like. The surface resistivity of the permanent antistatic PA66 / POE alloy can be up to 106-108 ohm.m.
Description
technical field [0001] The invention relates to a permanent antistatic masterbatch and a preparation method, in particular to a preparation method of a permanent antistatic PA66 / POE alloy. Background technique [0002] Nylon 66 has become the current application due to its good comprehensive mechanical properties, high heat resistance, good wear resistance, self-lubrication, good flame retardancy, excellent chemical corrosion resistance, and excellent barrier properties. The widest range of engineering plastics. POE is non-toxic, odorless, low density, low price, and has excellent properties such as aging resistance, ozone resistance, and chemical medium resistance. POE can be used as an impact modifier for engineering plastics, used in the production of impact-resistant mechanical parts, corrosion-resistant parts, automobiles, electrical parts and other products. Adding POE to PA66 can effectively improve its hygroscopicity and improve the stability of the product. At the...
