Description
Technical field
The invention belongs to technical field of polymer materials, is related to a kind of high intensity plating PC/ABS alloy materials and its preparation
Method.
Background technology
As a kind of common engineering plastics, makrolon (PC) because possess rigid phenyl ring and soft at the same time in its structure
The carbonic acid ester bond of property and had outstanding rigidity and toughness concurrently.But there is also such as poor fluidity, notch sensitive and heavy wall are sensitive
Deng physics shortcoming.For these problems, it is common practice to PC and other materials is blended, is particularly formed with ABS
PC/ABS materials, can well learn from other's strong points to offset one's weaknesses, there is obvious advantage in terms of mechanical property and processability, become automobile
The engineering plastics favored with industries such as household electrical appliances.
In the numerous applications of PC/ABS, it is as plated material to have a kind of application, is used in household electrical appliances, automobile interior exterior decorations etc.
Play a role on way.
According to the principle of plating, it is necessary to be performed etching to the rubber in material, so that substantial amounts of hole is formed, in favor of rear
Continuous sensitization activation and chemical nickel plating or copper facing.Therefore, in general, the rubber content electroplated in level PC/ABS can be significantly hotter than
The PC/ABS of common grade, meanwhile, the content of PC can be designed to than relatively low, in this way, it is good to ensure that plated material has
Upper plating ability and plating combine power.
But applied to the plating PC/ABS of automobile, two class products can be mainly processed into, one kind is electroplated decoration part, is such as adornd
Bar, label etc., and it is another kind of, it is functor, is exactly mainly door handle, shift wheel for air outlet etc..As it was previously stated, in order to ensure electricity
Performance is plated, general plating level PC/ABS has high glue amount and relatively low PC contents when being formulated design.And PC/ABS this
Intensity is provided by PC in one material, and only in the case that PC becomes principal phase, the performance of material can just access aobvious
The lifting of work.It can be said that the plating PC/ABS of mainstream more designs for decoration at present, when applied to door handle
When functor, its intensity is relative deficiency.This is also why many door handles are real in experience drawing experiment or fatigability
After testing, the reason for component fails.
Therefore, how while PC contents are improved, and ensure the upper plating ability of material, become numerous material producers one
It is straight to thirst for solving the problems, such as.
The content of the invention
It is an object of the present invention to overcome the above-mentioned drawbacks of the prior art and provide a kind of high intensity electroplates PC/
ABS alloy material and preparation method thereof.
The purpose of the present invention can be achieved through the following technical solutions：
A kind of high intensity electroplates PC/ABS alloy materials, which is made of the component of following parts by weight content：
Wherein, the mass content of DMF is 1~4% in the SAN master batches containing DMF.
Preferably, which is made of the component of following parts by weight content：
Wherein, the mass content of DMF is 2~3% in the SAN master batches containing DMF.
The addition of DMF can promote the swelling of PC well, material surface is become slightly loose, so as to promote to be roughened
Journey is reached, make blank be roughened after anchor close hole evenly with it is intensive.
Preferably, the makrolon is the poly- carbonic acid of bisphenol A-type that viscosity average molecular weigh is 20000~30000g/mol
Ester.
Preferably, the SAN master batches containing DMF are that the common extruding pelletizations of SAN and DMF are made.
Preferably, the viscosity average molecular weigh of the SAN is 100000~200000g/mol, in terms of weight percent content,
The mass content of acrylonitrile is 24~30% in SAN.
Preferably, the preparation of the SAN master batches containing DMF comprises the following steps：
SAN and DMF are placed in super mixer, 10~20min is mixed, obtains mixed material, mixed material is thrown into
In double screw extruder, it is 180~600rpm to control screw speed, by melting extrusion, is granulated, and obtains described containing DMF
SAN master batches.
Preferably, the viscosity average molecular weigh of the polybutadiene rubber powder is 100000~200000g/mol, and glue content is
50~60%.
Why preferably above-mentioned molecular weight ranges, be due to that principal phase is makrolon in the material, it is strong to be also to provide material
The component of degree and fatigue-resistance characteristics, higher PC molecular weight, can effectively lift the fatigue-resistance characteristics of material.SAN is as scattered
Phase, relatively low molecular weight can bring more preferable mobility, but be unlikely to largely to influence fatigue-resistance characteristics.It is poly-
The molecular weight of butadiene rubber powder is located in this section, it connects section entanglement degree and is more advantageous to material roughening.
Preferably, the antioxidant is in commercially available anti-oxidant Irganox 1010, Irganox1076 and Irganox168
One or more of mixing.
The combination of these antioxidant why is selected, is considered primarily for both sides：One is due to 1010 and 1076
It is good with the compatibility of PC/ABS materials, on the other hand it is desirable to by main anti-and auxiliary anti-collective effect, in extrusion, injection and long
During phase use for material provide more comprehensively with comprehensive protection.
The preparation method of the high intensity plating PC/ABS alloy materials, comprises the following steps：
SAN master batches containing DMF, makrolon, polybutadiene rubber powder and antioxidant are together added in mixer, mixed
Close 10~20min, obtain mixed material, mixed material thrown into double screw extruder, control screw speed be 180~
600rpm, by melting extrusion, is granulated, and the intensity plating PC/ABS alloy materials are made.
The engineers and technicians having gained some understanding to electroplating process are clearer, during plating, can undergo base material
Roughening link, this is also to determine one step of key that subsequently whether can well electroplate of material.At present for plastic electroplating,
It is substantially chemical roughening --- while etching, additionally it is possible to aoxidize base material, form more active group, so as to increase
The bonding state of strong subsequent chemistry coating.
And in fact, being roughened on surface in this technique, except carrying out chemical roughening using strong acid, there are two kinds of roughening sides
Method：One is what is carried out by the way of sandblasting shot-peening is mechanical coarsening, second it is molten using the not strong solvent progress of dissolubility
Swollen roughening.And for electroplating liquid medicine producer, in its tangible actual production, swelling roughening has been subjected to practical application.
On plating line of some needs with ABS mixed productions, if using the plating roughening suitable with ABS and follow-up work
Skill, PC/ABS products carry out a step and are roughened in advance sometimes, it is substantially exactly that PC/ABS is swollen using DMF equal solvents, is made
Material surface becomes more loose, so as to be conducive to the subsequent etching of strong acid.
Compared with prior art, the plating that the technique being roughened in advance is creatively introduced directly into high PC contents of the invention
In PC/ABS materials.Concrete operations are exactly in the formula design phase, can make PC that the DMF solvent being slightly swollen occur with regard to introducing,
During following process, the addition of DMF can promote the swelling of PC well, material surface is become slightly loose, so that
Promote coarsening process to reach, make blank be roughened after anchor close hole evenly with it is intensive, so as to bring the upper plating energy of higher
Power and plating yield.
