Toughened polyphenyl ether and nylon alloy and preparation method for toughened polyphenyl ether and nylon alloy

The invention discloses a toughened polyphenyl ether and nylon alloy and a preparation method for the toughened polyphenyl ether and nylon alloy. The toughened polyphenyl ether and nylon alloy comprises the following components in weight percentage: 20-60 percent of polyphenyl ether, 20-60 percent of polyamide, 5-20 percent of compatilizer, 5-20 percent of toughening agent and 1-2 percent of other additives. The incompatibility of the polyphenyl ether and nylon comprised by the invention is improved through the added compatilizer. Through changing the content of the toughening agent in the alloy material, the alloy material with different impact strength is obtained. A product prepared from the toughened polyphenyl ether and nylon alloy is capable of resisting the high temperature of at least 160 DEG C of a production line and the corrosion of dimethylbenzene and methylbenzene as solvents in spray paint; the contour dimension is kept unchanged; and the phenomena, such as stress cracking and the like, do not occur.
