It is a kind of with height adhesion, easy PC/ABS materials of plating and preparation method thereof
Technical field
The present invention relates to technical field of polymer materials, and in particular to a kind of PC/ with height adhesion, easily plating
ABS material and preparation method thereof.
Background technology
At present, the enclosure material of office appliance mostly is PC resin, ABS resin or PC/ABS compound resins.But, PC trees
Fat melt viscosity is big, machine-shaping is difficult, and particularly massive article easily produces stress cracking, and chemical proofing is poor, and
Price is higher, and these deficiencies make the application of PC receive a definite limitation;The performance of ABS resin is between engineering plastics and general-purpose plastics
Between, with good impact resistance and processing characteristics, price is also relatively cheap, and is widely applied.But its is heat-resisting
Property, weatherability are poor, and mechanical property is not ideal enough.PC/ABS alloys with PC and ABS as primary raw material are a kind of important engineerings
Plastic alloy, the characteristics of with good processing forming and corrosion resistance and toughness, but its heat resistance, weatherability are poor, mechanics
Performance is not ideal enough.And PC is chief component in PC/ABS alloy materials, this causes PC/ABS electroplating materials point quantity
It is greatly decreased, reduces the performances such as its electrodepositable, binding force of cladding material, it is impossible to which the performance for meeting higher and higher plated item will
Ask.Therefore, a intensity is developed high, easily the PC/ABS materials of plating are just necessary.
The content of the invention
For the problem that prior art is present, it is an object of the invention to provide it is a kind of with height adhesion, easily plating
PC/ABS materials and preparation method thereof.

It is connected on PS main chains, increased glass transition and heat distortion temperature.The heat change of general styrene-maleic anhydride copolymer product
Shape temperature is above 260 °F.In injection mo(u)lding, even if temperature is more than 550 °F, the performance of this polymer is still quite steady
It is fixed.
Carbon fiber is a kind of high intensity, the new fiber materials of high modulus fibre of phosphorus content more than 95%.It is by
The organic fibers such as flake graphite crystallite are piled up along fiber axial direction and are formed, and Jing is carbonized and microlite obtained from graphitization processing
Ink material.Carbon fiber " soft outside but hard inside ", quality is lighter than metallic aluminium, but intensity is higher than iron and steel, and with corrosion-resistant, high-modulus
Characteristic, be all important materials in defence and military and civilian aspect.It not only has the intrinsic intrinsic property of material with carbon element, has both again
The soft machinability of textile fabric, is reinforcing fiber of new generation.
Modified carbon fiber of the present invention is the aluminic acid by the PAN base carbon fibres of 95-98% weight and 2%-5% weight
Coupling agent is put into high-speed mixer, and at 100 DEG C, rotating speed is 750-800RPM, is well mixed.
It is further preferred that described aluminate coupling agent is anti-settling Aluminate ASA.
Preferably, the lubricant is alkyd ester lubricant, such as PETS lubricants, and inside and outside lubricity is good, can improve
The heat endurance of product, it is nontoxic.
Preferably, the preferred Hinered phenols antioxidant 1010 of the antioxidant is used as primary antioxidant, phosphite ester kind antioxidant
168 press 1 as synergistic antioxidant, wherein Hinered phenols antioxidant 1010 and phosphite kind antioxidant 168:2 proportionings.Wherein receive
, used as primary antioxidant, phosphite ester kind antioxidant 168 is used as synergistic antioxidant for resistance phenolic antioxidant 1010.
Preferably, the dispersant be ethylene acrylic acid co polymer, the such as 540A of Honeywell Inc. of the U.S..
The above-mentioned preparation method with height adhesion, the PC/ABS materials easily electroplated, comprises the following steps:
(1) raw material is weighed by weight, and each raw material input high-speed mixer and mixing is uniform, and mixing temperature is 55-65 DEG C, is mixed
Sum velocity is 550-600RPM, incorporation time 3-5 minute, obtains compound;
(2) compound Jing double screw extruders are made into material, at 230-260 DEG C, screw speed is for extruder temperature control
450-500RPM, by obtained pellet bar is molded into, and is obtained final product.
Beneficial effects of the present invention:
The characteristics of PC/ABS materials of the present invention have high intensity, easy plating, high tenacity, and moderate cost, size is steady
It is qualitative good, it is a kind of high comprehensive performance, the high alloy of cost performance.And the method for the present invention is simple, compatilizer draws
Enter to promote dispersion of the modified carbon fiber in PC/ABS matrixes so that minimal amount of carbon fiber can give PC/ABS alloy groups
The excellent electric conductivity of compound, reduces the linear expansion coefficient of composition, and can directly carry out electroplating work procedure, eliminates thick
Change, activation, Electroless Plating Procedure, simplify electroplating technology.The overall physical properties of material and the bond properties of material surface are improved,
The integrated cost of material is reduced, the use field of material has been widened.And the present invention in PC/ABS materials in strengthened feelings
Under condition, the light of integral material not being affected thoroughly, dissipating color effect, the resistance to temp effect of its entirety is good, is particularly well-suited to lamp decoration industry.
