Abstract

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.

Description

technical field [0001] The invention belongs to the field of polymer composite materials, and relates to a polyphenylene ether and nylon alloy material and a preparation method thereof. Background technique [0002] Polyphenylene ether resin (referred to as PPE or PPO) is a thermoplastic general-purpose engineering plastic and is one of the five major engineering plastics. It has good mechanical properties, electrical properties, heat resistance, flame retardancy, and low hygroscopicity, but pure PPO has high melt viscosity, poor processability, and is not resistant to corrosion by organic solvents. PA has good mechanical properties and is resistant to various organic solvents, but has the disadvantages of easy water absorption and unstable dimensions. The two form an alloy, which can complement each other. The PPO / PA alloy not only maintains the advantages of good heat resistance and dimensional stability of PPO, but also combines the wear resistance and organic solvent re...
