Description
Technical field
The invention belongs to technical field of polymer materials, and in particular to the sprayed on material article surface current mark flaw is exempted from a kind of solution
Acrylonitrile-butadiene-styrene (ABS) composition of defect and preparation method thereof.
Background technology
Exempt from spray thermoplastic engineering plastic be intended to by the material preparation stage to material assign metal appearance effect, from
And exempt the technology link that the later stage sprays again to product appearance, can reduce in this way production cost, shorten the development cycle,
The environmentally friendly purpose of the polluters such as the toxic, pernicious gas for reducing and being generated to environment in spraying process can be played.
However find to exempt to spray thermoplastic engineering plastic Injection moulded part in appearance more or less in the presence of some streams by putting into practice
Trace flaw, this makes the presentation quality of product receive discount greatly.To solve this problem, this large amount of side have also been made in engineers and technicians
The research work in face, can problem never effectively solved.
Invention content
To solve the above technical deficiency, it is an object of the present invention to provide a kind of solutions to exempt from sprayed on material article surface current mark flaw
Acrylonitrile-butadiene-styrene (ABS) composition and preparation method thereof.Invention one kind that provides creative from material is newly thought
The spraying-free metal effect of the solution of road technique route, the invention utilizes acrylonitrile-butadiene-styrene (ABS) composition to be used for
The product that injection molding is produced is completely eliminated in the apparent current mark flaw defect of product, is greatly improved outside product
Appearance quality reduces injection molding bad product rate, and considerable benefit is brought for production.
To achieve the above object, the present invention uses following technical proposals:
The acrylonitrile-butadiene-styrene (ABS) composition of spraying current mark is exempted from a kind of solution, by the component for including following parts by weight
It is made：
Acrylonitrile-butadiene-styrene resin：82~97.25 parts,
Light stabilizer：0.5~2 part,
Heat stabilizer：0.1~2 part,
Chemical treatments：2~10 parts
Processing aid：0.1~2 part,
Metal powder pigment：0.05~2 part.
Further, the acrylonitrile-butadiene-styrene resin is selected from acrylonitrile-butadiene-styrene (ABS) graft copolymerization
Object, acrylonitrile-ethylenepropylene elastomer-phenylethene grafted copolymer, acrylonitrile-styrene-acrylic ternary copolymer, methyl
The mixture of one or more of methylacrylate-butadiene-phenylethene grafted copolymer composition.
Further, the acrylonitrile-butadiene-styrene (ABS) by substance law produce obtain, relative density be 1.04~
1.07g/cm3, in 220 DEG C of test condition, 10 ㎏, melt mass flow rate is 2~10g/10min or more.
Further, the steady agent of the light is selected from benzophenone light stabilizer, benzotriazole light stabilizer, three nitrogen of benzo
One or more of mixtures is compounded in azole light stabilizer, hindered amine light stabilizer.
Further, the heat stabilizer is selected from Hinered phenols heat stabilizer, thioesters heat stabilizer, phosphorous acid esters
One or more of mixture in heat stabilizer.
Further, the chemical treatments are the super high molecular weight thermoplastic resin that molecular weight is more than 1,500,000.
Further, the processing aid be selected from solid paraffin, atoleine, low molecular weight polyethylene, stearic amide,
One or more of mixture in methylene bis stearic amide.
Further, the metal powder pigment is selected from the mixed of one or more of aluminium powder, silver powder, iron powder, nickel powder, zinc powder
Object is closed, the shape of metal powder pigment is sheet, and grain size is 1~900um.
A kind of preparation method for the resin combination solving to exempt to spray current mark, it is characterised in that：This method includes following step
Suddenly,
(1) each component raw material is weighed, 82~97.25 parts of acrylonitrile-butadiene-styrene resins, 0.5~2 part of light is steady
Determine agent, 0.1~2 part of heat stabilizer, 2~10 parts of chemical treatments, 0.1~2 part of processing aid, 0.05~2 part of metal powder pigment
It is uniformly mixed, obtains mixed material；
(2) mixed material obtained in step (1) is sent into double screw extruder, the conveying in screw rod and shear action
Under, material fully melts, is compound, then through head extrusion, tie rod, cooling, pelletizing；One district screw rod temperature of the double screw extruder
It is 200~220 DEG C；The extruder temperature of 2nd area to head is 220~260 DEG C；Screw speed is in 150~500r/min.
The present invention has the following advantages that compared with prior art：
1. the solution prepared in the present invention exempts to spray the acrylonitrile-butadiene-styrene (ABS) composition of current mark, due to using high
Viscosity, eutectic fat resin material, then coordinate super high molecular weight thermoplastic resin modified so that composition melt can be with a kind of stabilization
State flowing, melt front flow velocity is steady, reduces narrow runner and cast gate enters injection effect in spacious die cavity
It answers；Simultaneously because composition melt molecular weight is larger, viscosity is larger, metal powder pigment can be preferably driven to flow together in flowing
It is dynamic, more metal powder pigment is coated in melt flows forward position, eliminates and exempts to spray thermoplastic engineering plastic Injection moulded part
The open defect of upper current mark flaw.
2. the composition base selection of the present invention is clearly different from the choosing to acrylonitrile-butadiene-styrene (ABS) base-material in the past
Select thinking, the thinking that conventional art personnel solve injection molding current mark be all start with from the mobility for improving melt, but the present invention from
Reversed thinking selects eutectic to refer to, the solution of the high viscosity resins of low flowing, improves material hair and is split into power, greatly carries
High product appearance quality reduces injection molding bad product rate, and considerable benefit is brought for production.
3. chemical treatments is used to be more than 1,500,000 super high molecular weight thermoplastic resin for molecular weight in the present invention, reduce
The unstable state of injection molding and stable direction state.
4. due to using new resolving ideas, eutectic is selected to refer to, the resin of mobility, cooperation high molecular weight resin is compound,
So that the mobility of composition entirety reduces while molecular weight increase, such melt can be more to balance when flowing mold filling
Mode flows, and avoids that high fluidity causes the unexpected velocity perturbation of melt, become larger the injection defect brought；Simultaneously metal powder face
Material is coated in melt flows forward position, these are fundamentally thoroughly solved from material end exempts to spray thermoplastic engineering plastic for noting
It is moulded into type and there are problems that current mark flaw, need not consider further that the influence of the factors such as mold, cast gate, structure design, reduce
Development cost.
