Abstract
The invention relates to a permanent antistatic polyphenylene sulfite (PPS)/poly-p-phenylene oxide (PPO) alloy and a production method thereof, wherein the material comprises the following component in percentage by weight: 3-8% of antistatic masterbatch, 40-45% of PPS, 40-50% of PPO and 1-5% of compatilizer, raw materials are placed into a high speed mixer according to the weight percentage to mix for 2-5 min, are discharged, and are extruded and granulated through a double-screw extruder, the processing temperature is between 285-325 DEG C, and the rotational frequencies of screws are 35-40Hz. Compared with the prior art, the invention has the advantages of permanent antistatic effect, realization of permanent antistatic effect, good antistatic effect and higher comprehensive mechanical property; and being approximate to the performance of the pure PPS/PPO alloy, having light color, being capable of being made up into other colors, and having low cost, good heat-resistant quality and the like. The surface resistivity of the PPS/PPO alloy can reach 106-108 omega.m.
Description
Technical field [0001] The invention relates to a permanent antistatic masterbatch and a preparation method, in particular to a permanent antistatic PPS / PPO alloy preparation method. Background technique [0002] PPO has the advantages of high rigidity, high heat resistance, good water resistance, flame resistance, 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 in the engineering It is one of the smallest varieties of plastics, and it is hardly affected by temperature and humidity, and can be used in low, medium and high frequency electric fields. The load deformation temperature of PPO can reach above 190℃, and the embrittlement temperature is -170℃. PPS has the advantages of high mechanical strength, high temperature resistance, high flame retardancy, and strong chemical resistance; it has the advantages of hard and brittle, high crystalli...
