Abstract

A modified polyphenylene oxide material is provided. The modified polyphenylene oxide material is prepared from 30-70 parts by weight of polyphenylene oxide, 12-40 parts by weight of polystyrene, 5-30 parts by weight of reinforcing fibers, 3-10 parts by weight of a filler, 0.2-0.7 part of a lubricant, 0.2-0.5 part by weight of an antioxidant and 0.3-1.0 part by weight of a coupling agent. A preparing method of the modified polyphenylene oxide material is also disclosed. The method includes weighing the 30-70 parts by weight of the polyphenylene oxide, the 12-40 parts by weight of the polystyrene, the 3-10 parts by weight of the filler, the 0.2-0.7 part of the lubricant, the 0.2-0.5 part by weight of the antioxidant and the 0.3-1.0 part by weight of the coupling agent, fully mixing through a high-speed mixer, adding the mixture into a screw extruder, feeding the 5-30 parts by weight of the reinforcing fibers through a side feeding port of the extruder, drawing into bars through the screw extruder, and granulating to obtain the modified polyphenylene oxide material. The polyphenylene oxide is adopted as a base material. The polyphenylene oxide has good electric properties, has the minimum dielectric loss factor in engineering plastics, and is low in influences by frequency and temperature. Products of the material can be widely used for electrommunication products.

Description

technical field [0001] The invention belongs to the technical field of polymer materials, and in particular relates to a modified polyphenylene ether material with high strength and low dielectric loss and a preparation method thereof. Background technique [0002] Dielectric loss refers to the phenomenon that the dielectric itself heats up due to the consumption of a part of the electric energy in the alternating electric field. The polarity of polymer molecules, the density of polar groups and the mobility of polar groups are the internal reasons that determine the dielectric loss of polymers. The greater the polarity of polymer molecules and the greater the density of polar groups, the greater the dielectric loss. Generally, a polymer with a larger dipole moment has a larger dielectric loss. With the rapid development of information, electronics and electric power industries, the production of composite materials with low dielectric loss that can be used in electronic c...
