Abstract
The present invention discloses a kind of PC/ABS alloys and preparation method thereof, it is characterised in that：The alloy is made up of each component of following percentage by weight：PC/ABS：70% 95%, the PA6 containing mineral powder：5% 30%；PC contents in described PC/ABS are 50% 80%, and containing 20% 40% mineral powder in the PA6 containing mineral powder, and the particle diameter of mineral powder is nano-scale range.PC content in rationally control PC/ABS of the invention, and the content of PA6 Minerals powder, why in PC/ABS PC content control it is higher be because, PC contents are higher, the plating performance of PC/ABS materials is poorer, but the mechanical property of material is stronger, and the invention cleverly adds mineral powder to strengthen the plating performance of the PC/ABS materials of this high PC contents with PA6.
Description
Technical field
The present invention relates to PC/ABS technical field of alloy, and in particular to a kind of PC/ABS alloys and preparation method thereof.
Background technology
PC/ABS alloy plastics can be made in makrolon (PC) and acrylonitrile-butadiene-styrene (ABS) (ABS) plastics, this
Kind of alloy plastic combines the excellent properties of two kinds of materials, i.e. the processability of ABS material and PC mechanical property and heatproof, anti-
The properties such as ultraviolet, can be extensively using on automotive interior parts again, Business Machine, the communication apparatus, electrical home appliances and lighting apparatus.
And these PC/ABS alloys due to the characteristic of performance and the characteristic of application field, it is necessary to carry out electroplating processes；And the plating of plastics
Not only technics comparing is complicated, and the requirement to plastic basis material is higher, and the surface property of base material is very big on electroplating effect influence,
In addition, the composition of base material can also impact to plating performance.
At present, the PC/ABS materials of prior art, the process of chromic acid chemistry roughening is being used, although butadiene therein is
Rubber bodies are oxidized easily corrosion, leave a large amount of small holes in continuous resin phase surface, realize the plating of electroplating process
Combination between layer and base material, but this single hole adhesion still has certain deficiency, and process is used also in the later stage
Can a certain degree of generation for causing craze of coating, obscission.
The content of the invention
The technical problems to be solved by the invention are the shortcomings that overcoming above prior art：It is good to provide a kind of plating performance,
The PC/ABS alloys that electrodeposited coating is not easy to crack, comes off.
The technical solution of the present invention is as follows：A kind of PC/ABS alloys, the alloy by following percentage by weight each group
It is grouped into：PC/ABS：70%-95%, the PA6 containing mineral powder：5%-30%；PC contents in described PC/ABS are
Mineral powder containing 20%-40% in 50%-80%, the PA6 (nylon 6) containing mineral powder, and the particle diameter of mineral powder
For nano-scale range.
Preferably, mineral powder of the present invention can be in talcum, wollastonite, silica flour, titanium oxide and zinc oxide
One kind, or the mixing of more than one arbitrary proportions；Particle diameter is 1-100nm.
Preferably, the PC/ABS alloys that the present invention is above-mentioned, the alloy are made up of each component of following percentage by weight：
PC/ABS：75%-90%, the PA6 containing mineral powder：10%-25%；PC contents in described PC/ABS are 55%-75%,
Mineral powder containing 25%-35% in the described PA6 containing mineral powder, and the particle diameter of mineral powder is nano-scale range.
Preferably, PA6 of the present invention is plating level PA6, for example can be 73M40, BG30, D121-GF15,
Akro B3GK50, EMS BG6-BK, BM 240H1.0, BASF B3S, Bayer BM240H2.0, You Nijisi A1030GFLBK,
EMS BG30/2BK one or more of mixtures).
The present invention also provides a kind of preparation method of above-mentioned PC/ABS alloys, and specific steps include：
(1) raw material PC, ABS and PA6 containing mineral powder are dried first, drying temperature is 95-100 DEG C, the time
For 4-8 hours；
(2) and then by the raw material after drying according to formula rate add in double screw extruder, be 185 in extrusion temperature
DEG C -260 DEG C, screw speed carries out batch mixing extrusion under conditions of being 200-600rpm, obtains target product.
The present invention is divided into two feed hoppers and fed before double screw extruder is added, because PC/ABS and containing
Have both raw materials of the PA6 of mineral powder, its density of material is different, two feeding hoppers, feeding hopper FREQUENCY CONTROL in 55-65 hertz,
It can substantially ensure that two kinds of material feedings are uniform.
The advantages of the present invention：
1. the present invention adds the PA6 and mineral powder of plating grade in PC/ABS materials first；It so can be achieved with electricity
The reinforcement of performance is plated, is primarily due to：Butadiene is rubber bodies in PC/ABS, can be roughened by chromic acid, forms hole, so as to convenient
Electroplate Stromal Precipitation attachment；Plating level PA6 possess in itself plating performance (PA6 base materials and mineral powder due to it is incompatible exist it is tiny
It is easy to plating crystallization apposition growth in gap)；There is incompatibility in both PC/ABS and the plating level PA6 containing mineral powder, blending
Afterwards there is small thin trace in product material, help to electroplate matrix adventitious deposit；3 points of the above is combined to strengthen PC/ABS electricity
Plate performance.
2. PC content in rationally control PC/ABS of the invention, and the content of PA6 Minerals powder, why PC/ABS
The higher of middle PC content control is because PC contents are higher, and the plating performance of PC/ABS materials is poorer, but the power of material
It is stronger to learn performance, and the invention cleverly adds mineral powder to strengthen the PC/ABS materials of this high PC contents with PA6
The plating performance of material.
