[0047] The preparation method of the polyphenylene ether composite material provided in the embodiment of the present invention is to mix the dried polyphenylene ether, liquid crystal polyester resin and filler, melt and knead, and then extrude and granulate to obtain a polyphenylene ether composite material. Material. The embodiment of the present invention contains polyphenylene ether composite materials such as polyphenylene ether, liquid crystal polyester resin and fillers. Through the interaction between the components, the polyphenylene ether composite material ...

Embodiment 1

[0062] 65 parts of polyphenylene ether, 5 parts of wholly aromatic liquid crystal polyester resin (Jiangsu Water Special Material Manufacturing Co., Ltd.), and 30 parts of glass fiber were dried at 130° C. for 6 hours. Put the dried polyphenylene ether, liquid crystal polyester resin and glass fiber into an automatic mixer to mix evenly, then put them into a twin-screw extruder for melting and mixing, and then produce polyphenylene ether through extrusion, drawing, cooling, and granulation Composite material.

Embodiment 2

[0064] 60 parts of polyphenylene ether, 10 parts of wholly aromatic liquid crystal polyester resin (Jiangsu Water Special Material Manufacturing Co., Ltd.), and 30 parts of glass fiber were dried at 130° C. for 6 hours. Put the dried polyphenylene ether, liquid crystal polyester resin and glass fiber into an automatic mixer to mix evenly, then put them into a twin-screw extruder for melting and mixing, and then produce polyphenylene ether through extrusion, drawing, cooling, and granulation Composite material.

Abstract

The invention belongs to the technical field of polymer composite materials, and particularly relates to a polyphenyl ether composite material. The polyphenyl ether composite material comprises 50-70parts of polyphenyl ether, 3-20 parts of liquid crystal polyester and 10-30 parts of filler. Through the combined action of the components of the polyphenyl ether, the liquid crystal polyester and thefiller, the flowability and the moldability of the polyphenyl ether composite material are improved, the mechanical property and the thermodynamic property are improved, and the polyphenyl ether composite material can be widely applied to the aspects of electronic appliances, automobiles, household appliances, office equipment, industrial machinery and the like.

Description

technical field [0001] The invention belongs to the technical field of polymer composite materials, and in particular relates to a polyphenylene ether composite material and a preparation method thereof. Background technique [0002] Polyphenylene oxide (PPO) is one of the world's five general-purpose engineering plastics. It has the advantages of high rigidity, high heat resistance, flame retardant, high strength and excellent electrical properties. In addition, PPO also has the advantages of wear resistance, non-toxicity and pollution resistance. The dielectric constant and dielectric loss of PPO are one of the smallest varieties among engineering plastics, and they are hardly affected by temperature and humidity. However, polyphenylene ether is similar to Newtonian fluid, has poor fluidity, viscosity is sensitive to temperature, and is easy to decompose. Therefore, the processing and molding performance of polyphenylene ether is extremely poor, and pure polyphenylene e...
