Description

The high-performance glass strengthens the polyphenyl ether/nylon Alloy And Preparation Method

Technical field

The present invention relates to a kind of polyphenyl ether/nylon alloy, relate in particular to a kind of high-performance glass and strengthen the polyphenyl ether/nylon Alloy And Preparation Method.

Background technology

Ppe (Polyphenylene ether is called for short PPE or PPO) is a kind of have good mechanical performance, chemicalstability, dielectric properties, thermotolerance and flame retardant resistance, is a kind of high performance thermoplastic engineering plastic.After GE company released first-generation modified polyphenyl ether product (Norly) in 1966, the ppe industry developed rapidly, has become the fourth-largest engineering plastics of the PA that continues, PC, POM.The ppe of non-modified has good mechanical performance, thermotolerance, dimensional stability, chemicalstability, hydrolytic resistance, high rigidity and flame retardant resistance etc.; But PPO molecular chain rigidity is bigger; Notch shock is very responsive; Simultaneously because its higher melt viscosity, make it can not injection moulding, therefore limited its application greatly.

Nylon is as one of the most tough and tensile thermoplastic engineering plastic of a kind of excellent performance, widespread use, and its processing fluidity is good, is easy to machine-shaping; Because the amido linkage in its molecular structure is prone to form hydrogen bond, thereby makes it have excellent mechanical property, thermal property, winter hardiness and creep resistance, exactly because but also the existence of hydrogen bond make that its water-intake rate is high, poor dimensional stability.

PPO and PA inherent performance shortcomings have determined the complementarity of alloy property between the two, and this just makes the PPO/PA alloy become the most excellent alloy material of over-all properties, also becomes development in recent years one of polyblend faster.But ppe is amorphous and nonpolar resin; Nylon is crystal type and polar resin, and the two is complete incompatible system, and the two all exists breach responsive simultaneously; The defective that impact property is relatively poor, thereby the exploitation of high-intensity high-tenacity glass enhanced PPO/PA alloy product is very difficult.
