Abstract
The invention relates to a glass fiber reinforcement polyphenyl ether / polypropylene alloy and a production method thereof, wherein the alloy comprises the following component in part by weight: 10-50% of polyphenyl ether (PPO), 10-50% of polypropylene (PP), 3-15% of flexibilizer, 10-40% of glass fibre, 5-15% of polyphenyl ether-polypropylene compatilizer, 0.2-0.6% of antioxygen, 0.2-1% of lubricant and 0.2-0.8% of uvioresistant. The production technology 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 long glass fibre is added from the glass fibre inlet of the double-screw extruder and is then granulated, the temperature is controlled between 220-250 DEG C, screws are controlled between 300-600r, so the glass fiber reinforcement polyphenyl ether / polypropylene alloy material can be obtained. The invention has the advantages of good stretching, bending and impacting performance, heat resistance, weather resistance, creep resistance, size stability, easiness in machine shaping and the like, and is applicable to automobile parts, pipe fittings, valve valves and the like.
Description
technical field [0001] The invention relates to a polyphenylene ether / polypropylene alloy, in particular to a glass fiber reinforced polyphenylene ether / polypropylene alloy and a preparation method thereof. Background technique [0002] Polyphenylene ether (PPO) has good mechanical properties, chemical stability, dielectric properties, heat resistance and flame retardancy, and is a high-performance thermoplastic engineering plastic. However, the molecular chain of PPO is relatively rigid, the melt viscosity is high, the processability is poor, the price is high, and the product is easy to crack. Polypropylene has good electrical insulation properties, low water absorption, good fluidity, easy molding, good chemical stability, and low cost. However, polypropylene as a general-purpose plastic has poor physical and mechanical properties and heat resistance. Therefore, the preparation of polyphenylene ether / polypropylene alloy can improve the shortcomings of both, combine the a...
