Description
Technical field
The present invention relates to a kind of improved PC (Polycarbonate, polycarbonate)-ABS resin alloy and production method, it belongs to thermoplastic resin composition field in the high polymer material technology.
Background technology
The PC-ABS resin alloy is polycarbonate and acrylonitrile-butadiene-styrene copolymer and mixture, it is the thermoplastic plastic rubber that is formed by polycarbonate (Polycarbonate) and polyacrylonitrile (ABS) alloy, in the PC-ABS resin alloy, the content of general PC is greater than 50%, described PC-ABS resin alloy combines the excellent specific property of PC and two kinds of materials of ABS, the formability of ABS material and the mechanicalness of PC have been comprised, shock strength and heatproof, uvioresistant character such as (UV) can be widely used in automotive interior parts, business machine, the communication apparatus, on electrical home appliances and the set lights.In concrete application, general manufacturer all can carry out modification further and handle according to specific application demand on the basis of simple PC and ABS resin alloy material, satisfies the needs of using to make it final material property.ZL200610035661.3 discloses a kind of such, carry out the PC-ABS resin alloy material that further modification is handled on the basis of simple PC and ABS resin alloy material, the PC-ABS resin alloy material of the disclosed this further modification of ZL200610035661.3, form institute by following component according to the mass fraction and constitute:
Wherein, described graft copolymer is ABS-g-MAH, SEBS-g-MAH or PS-g-MAH; Described toughner is MBS, MMB or ASA.
Aforementioned blend composition is by mixing granulator in the forcing machine, and the gained mixing granulator is made final finished product through injection molding.
The problem that the disclosed this PC-ABS resin alloy of ZL200610035661.3 exists is that its shock strength index is at 35-43KJ/m
2Between, find the electronic product casing that the employing previous materials is made during use, the inlay card position often fractures when the maintenance dismounting, obviously be that such shock strength index does not satisfy it as the application needs of some electronic product casings, such as the needs that obviously do not satisfy as handset sheathing material, simultaneously, cost is also higher relatively, according to the above, obviously prior art has further improved necessity.
