Problems solved by technology
In the prior art, nylon, polyphenylene ether, compatibilizer, and processing aid are usually added to the extruder to melt and extrude, because the active groups in the compatibilizer are easy to react with nylon and are completely dispersed in the extruder. In the nylon phase, it is difficult to stay at the interface between polyphenylene ether and nylon to play a compatible role, so the outstanding cold resistance, heat resistance, chemical resistance and mechanical properties of PPE and PA cannot be fully utilized.

The invention discloses a composition of polyphenyl ether and nylon and a preparation method thereof. The method for preparing the composition of the polyphenyl ether and nylon comprises the following steps of: a granulating step: uniformly mixing a phase solvent and polyphenyl ether, adding the mixture into a dual-screw extruder to be molten and extruded, and cooling, drying and granulating the extruded mixture; a preparation step of the composition: uniformly mixing the particles obtained in the granulating step, the nylon, any antioxidant and any lubricant, adding the mixture into the dual-screw extruder to be molten and extruded, and cooling, drying and granulating to obtain the composition of the polyphenyl ether and nylon. The invention also provides a composition of the polyphenyl ether and nylon obtained through the method. According to the composition of the polyphenyl ether and nylon obtained in a two-step method, the phase solvent and the polyphenyl ether are molten and extruded to be granulated, the obtained particles are blended with the nylon, any antioxidant and any lubricant to be extruded, and the surface of the obtained composition is smooth, and the mechanical performance is excellent.
Description
technical field [0001] The invention relates to the field of macromolecules, in particular to a composition of polyphenylene ether and nylon and a preparation method thereof. Background technique [0002] At present, there are very few modified polyphenylene ethers (PPE) in China, and the modified PPE is mainly modified with polystyrene (PS). The PPE modified with nylon (PA) is currently only GE company in the United States. In the prior art, nylon, polyphenylene ether, compatibilizer, and processing aid are usually added to the extruder to melt and extrude, because the active groups in the compatibilizer are easy to react with nylon and are completely dispersed in the extruder. In the nylon phase, it is difficult to stay at the interface between polyphenylene ether and nylon to play a compatible role, so the outstanding cold resistance, heat resistance, chemical resistance and mechanical properties of PPE and PA cannot be fully utilized.
