Description
Technical field
The invention belongs to technical field of polymer materials, be specifically related to a kind of wear-resisting polyethylene terephthalate moulding compound.
Background technology
Because polyethylene terephthalate has excellent intensity and resistance toheat, thereby is widely used in fields such as automobile, electronics, machinery, instrument.But, because automotive field requires higher and more harsh to fatigue performance, resistance toheat and wear resisting property to this strength of materials, therefore common polyethylene terephthalate moulding compound also is difficult to adapt to this harsh requirement, must further improve its intensity, temperature tolerance etc. by modification.Chinese patent publication number CN102311616A discloses carbon fiber reinforced polyester, still, owing to raw material sources are restricted, thereby can not form scale production.In view of this, be necessary to be explored, the applicant does actively and good try has formed technical scheme described below finally for this reason.
