Description
Technical field
The invention belongs to new material technology field, more particularly to a kind of PC/SAN/GF composites and preparation method thereof.
Background technology
Makrolon（PC）Material is a kind of thermoplastic with high mechanical properties, high tenacity and high-fire resistance, extensively
It is general to be applied to household electrical appliance and field of electronics.Glass fibre（GF）It is that a kind of makrolon is extensive to strengthen modified polycarbonate
Modified method, there is high rigidity, high mechanical properties and low-shrinkage by the GF polycarbonate composite materials being modified；But simultaneously
Surface floating fiber influences product appearance, thus in some application fields, such as article surface needs vacuum coating etc., serious surface
Floating fibre can influence the Vacuum Deposition yield of product, and modified by glass, and reduction influence product occurs in composite fluidity
Processing and manufacturing.In addition, SAN（SAN）There is preferable compatibility with PC, and SAN is in itself with higher
Rigidity and intensity, will not significantly affect the mechanical performance of PC/GF composites, and soaring with makrolon price, in section
Save manufacturing cost to consider, cheap SAN resins are preferable selections.
Present technical barrier is as follows：
1st, SAN is added to PC/GF composite systems, and material can become fragile, it is difficult to carry out toughness reinforcing processing to it, so substantially can not
Reach and use required mechanical performance.
2nd, the addition of glass fibre can influence product appearance, the non-defective unit of process after serious surface floating fiber can even influence
Rate.
3rd, the selection of glass fibre is the formula factors of an important consideration, and selection is improper to cause mechanical performance not good, table
Face is floating fine serious.
