Abstract

The present invention relates to a PPO solid-phase graft compatibilizer, a production method of the PPO solid-phase graft compatibilizer and several alloys using the PPO solid-phase graft compatibilizer, characterized in that : By weight, including 100 parts of polyphenylene ether (PPO) particles or powder, 0.5 to 2.5 parts of maleic anhydride (MAH), and 0.1 to 0.6 parts of initiator; the production method is to use a reactor with a stirring paddle to manufacture The reaction temperature of the reactor is 75-95°C, the stirring speed is 10-150RPM, and the reaction time is 10-15H; the reactor can also be filled with inert gases such as nitrogen for protection; the compatibilizer produced by the present invention alloy, its compatibility is better, and the mechanical effect of the alloy is better.

Description

technical field [0001] The invention relates to a PPO solid-phase graft compatibilizer, a preparation method thereof, and a PPO alloy containing the compatibilizer. Background technique [0002] Polyphenylene oxide (PPO, Polyphenylene Oxide) is a high-strength engineering plastic developed in the 1960s. Its chemical name is poly 2,6-dimethyl-1,4-phenylene oxide. It is a thermoplastic engineering plastic with good Excellent heat resistance, good mechanical properties, good electrical properties, good acid and alkali resistance; but because of its high melting temperature, high melt viscosity, difficult processing and other factors, it needs to be modified for use. [0003] The traditional PPO modification technology is the melt grafting method, which uses a high temperature of more than 200 degrees to melt PPO, adds other high polymers, and then extrudes through a twin-screw extruder. The method has the following problems: high reaction temperature, poor versatility of the r...
