Abstract

The invention relates to a high-performance glass fiber reinforcement polyphenyl ether / polyamide alloy and a production method thereof, wherein the alloy comprises the following components in part by weight: 20-50% of polyphenyl ether (PPO), 10-50% of polyamide (PA), 2-20% of hydrogenation segmented copolymer, 10-40% of glass fibre, 5-15% of polyphenyl ether-polyamide compatilizer, 0.2-0.6% of antioxygen and 0.2-0.6% of uvioresistant. The production technology of the reinforcement PPO / PA alloy comprises the following processes that: firstly, raw materials are mixed according to the proportion, and then are added into a double-screw extruder through a feeder, the glass fibre is added through a side feeder, the temperature is controlled between 240-280 DEG C, then granulation is carried out, so the high-performance glass fiber reinforcement polyphenyl ether / polyamide alloy can be obtained. The invention has the advantages of good high and low temperature mechanical property, heat resistance, weather resistance, creep resistance, insulativity, easiness in machine shaping and the like, and is applicable to electric product parts, automobile parts, office parts and the like.

Description

technical field [0001] The invention relates to a polyphenylene ether / nylon alloy, in particular to a high-performance glass fiber reinforced polyphenylene ether / nylon alloy and a preparation method thereof. Background technique [0002] Polyphenylene ether (PPE or PPO for short) is a high-performance thermoplastic engineering plastic with good mechanical properties, chemical stability, dielectric properties, heat resistance and flame retardancy. Since GE launched the first-generation modified polyphenylene ether product (Norly) in 1966, the polyphenylene ether industry has developed rapidly and has become the fourth largest engineering plastic after PA, PC, and POM. Unmodified polyphenylene ether has good mechanical properties, heat resistance, dimensional stability, chemical stability, hydrolysis resistance, high rigidity and flame retardancy, etc., but the PPO molecular chain is relatively rigid and is very sensitive to notch impact , At the same time, due to its high me...
