Abstract

The invention provides a compatilizer and a preparation method thereof, and particularly relates to the production of the compatilizer for a polyphenyl ether/polypropylene alloy, wherein the compatilizer is a graft polymer, and is obtained after the grafting reaction of styrene ethylene butadiene segmented copolymer, polyphenyl ether, maleic anhydride monomer, peroxide, initiator and processing aid. The components of the styrene ethylene butadiene segmented copolymer, the polyphenyl ether, the maleic anhydride monomer and the processing aid except the peroxide and the initiator are proportionally placed in a high speed mixer to mix, then the peroxide is fed into a double-screw extruder through a main feeder, the initiator is added into the extruder through a side feeder, and after liquation plasticizing, kneading and mixing, handpiece extrusion, strip drawing, cooling, grain sized dicing and drying, the compatilizer product is obtained. The compatilizer, the polyphenyl ether, polypropylene, flexibilizer and antioxidant are proportionally placed into a mixer to mix, and then are added into the double-screw extruder to plasticize and extrude, so the polyphenyl ether/polypropylene alloy is obtained.

Description

technical field [0001] The invention relates to a plastic compatibilizer and a preparation method thereof, including a polyphenylene ether / polypropylene alloy containing the compatibilizer and a preparation method thereof; especially relates to a compatibilizer and a compatibilizer for a polyphenylene ether / polypropylene alloy Its preparation method, polyphenylene ether / polypropylene alloy containing the compatibilizer and its preparation method. Background technique [0002] Polyphenylene ether (PPO) resin was first produced by GE Company of the United States in 1957, and industrialized production was realized in 1964. Due to the difficulty in processing PPO resin, it is difficult to apply it in practice. It was not until 1966, after GE developed modified PPO resin, that modified PPO achieved rapid development as a general engineering plastic with its excellent performance and many grades. The fifth largest general-purpose engineering plastic after PC, POM, and PBT / PET. P...
