The industry such as device and civil field.However ABS, there are some defects, such as weatherability are bad, thermal stability is poor, and heat-resisting quantity is poor,
It is obviously deteriorated when at -20 DEG C, its impact resistance is compared with room temperature.Polyacrylonitrile in ABS material mutually primarily serve increase rigidity and
Improve the effect of heat deformability, the polybutadiene mutually main effect for playing impact resistance.Polyacrylonitrile and polybutadiene phase
It is a pair of contradictory body, there is the relationship that this disappears and other rises.Therefore pass through conventional modified method, it is difficult at the same obtain high temperature resistant deformation and
The ABS material of low-temperature impact-resistant ability.
Fibrous material has high tensile strength along fiber extension direction, the fibers such as usual glass fibre, carbon fiber
The intensity and heat-resistant deforming ability that can greatly improve thermoplastic resin is added.General fibre reinforced materials needs to carry out fiber
Special pretreatment adds compatilizer to increase the binding force between fiber and resin, such as carbon fiber needs in advance in carbon fiber
Peacekeeping fiberglass surfacing carries out special slashing operation, and compatilizer is added in resin.
Above-mentioned processing method can greatly improve the interaction force between fiber and resin two-phase, and then promote fiber reinforcement
The overall performance of material.But the addition of inorfil usually will increase density of material, in some necks for needing lightweighting materials
Domain, higher density can reduce the competitive advantage of material, special pretreatment and the addition of compatilizer can improve difficulty of processing or
Increase material cost, therefore existing fiber reinforcement ABS material be difficult obtain high-strength and high ductility while, have low-density, prepare
The requirement of simple process.
