Abstract

The invention relates to PP / PPO alloy with permanent antistatic performance and a preparation method thereof. The alloy comprises the following components by weight percent: 3 to 8% of antistatic master batches, 40 to 45% of PP, 40 to 50% of PPO and 1 to 5% of a compatilizer, and is prepared by weighing the above-mentioned raw materials by weight, putting the raw materials into a high-speed mixer for mixing for 2 to 5 min, discharging a material and carrying out extrusion and granulation on the material with a double-screw extruder, with processing temperature to be 245 to 285 DEG C and the revolution of screws to be 35 to 40 Hz. The PP / PPO alloy provided in the invention has a lasting antistatic effect, realizes a permanent antistatic effect, has the advantages of a good antistatic effect, high comprehensive mechanical properties, performance close to that of pure PP / PPO alloy, a light color capable of being blended into a variety of colors, low cost, good heat resistance, etc., and has surface resistivity up to 106 to 108 omega.m.

Description

technical field [0001] The invention relates to a permanent antistatic masterbatch and a preparation method. The invention also relates to a preparation method of the permanent antistatic PP / PPO alloy. Background technique [0002] 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 are important in engineering It is one of the smallest types of plastics, and is hardly affected by temperature and humidity, and can be used in low, medium and high frequency fields. The load deflection temperature of PPO can reach above 190°C, and the embrittlement temperature is -170°C. PP is non-toxic, tasteless, low density, low price, and has good electrical properties. Common acid and alkali organic solvents have little effect on it. It is suitable for makin...
