Description
Technical field
The invention belongs to modified material technical field more particularly to a kind of straw powder modification regeneration ABS (acrylonitrile-fourths two
Alkene-styrol copolymer) composition and preparation method thereof.
Background technique
Styrene-acrylonitrile-butadiene copolymer (abbreviation ABS) is grown rapidly in nearly half a century, due to it
Its good impact resistance, heat resistance, dimensional stability and outstanding glossiness and electric property, in electric, automobile
Extremely extensive use has been obtained in industry.
Straw powder modification regeneration acrylonitrile-butadiene-styrene copolymer composition, can not only make full use of regeneration third
Alkene nitrile-butadiene-styrene copolymer (acrylonitrile-butadiene-styrene copolymer after the recovery), can also reduce cost.
Modified plastic industry application straw powder is a kind of behave turned waste into wealth, and can give increasing peasant income.
However, there are the following problems for meeting by hot-forming: 1, straw powder and regeneration acrylonitrile-butadiene-styrene
Copolymer poor compatibility, final products poor mechanical property；2, regenerate acrylonitrile-butadiene-styrene copolymer and straw powder by
It differs greatly in bulk density, is difficult to be uniformly mixed；3, for straw powder in mixing, shearing force is stronger when due to batch mixer mixing,
Straw powder is easily burnt.
Summary of the invention
The object of the invention is to provide a kind of straw powder modification regeneration ABS to overcome above-mentioned prior art defect
The preparation method of composition.
A kind of straw powder modification regeneration ABS composition, is prepared by weight by following components:
100 parts of regeneration ABS (acrylonitrile-butadiene-styrene copolymer)
1-2 parts of decyl amide
25-55 parts of straw powder
2-3 parts of isocyanates
0.3-0.8 parts of antioxidant.
Further scheme, the partial size of the straw powder are 80-100 mesh.
The moisture content < 2% of the moisture content < 4% of the regenerating polypropylene, straw powder.
The antioxidant is selected from three (2.2- di-tert-butyl-phenyl) phosphite esters, four (β-(3,5- di-t-butyl -2- hydroxyls
Base phenyl) propionic acid) at least one of pentaerythritol ester and the double octadecyls of thio-2 acid.
Another goal of the invention of the invention is to provide a kind of above-mentioned straw powder modification regeneration acrylonitrile-butadiene-benzene second
The preparation method of alkene copolymer composition, its step are as follows:
(1) 100 parts of regeneration ABS, 1-2 parts of decyl amide are weighed, are added in batch mixer ,/min mixing 2-5 is turned with 600-800
Minute；
(2) it weighs in the batch mixer that 22-55 parts of straw powder are added in step (1) ,/min mixing 2-5 is turned with 300-400
Minute；
(3) 2-3 parts of isocyanates are added, 0.3-0.8 parts of antioxidant, continuess to mix 1-2min；
(4) mixture through step (3) is placed in precompressed in mold, hot-forming straw powder modification regeneration polypropylene group
Close object.
Further scheme, in the step (4) pressure of precompressed be 2-3mpa, time 10-30s；Hot-forming temperature
Degree is 160-200 DEG C, pressure 20-100mpa, time 5-10 minute.
Decyl amide can play the role of lubrication, bonding in the present invention.
Straw powder partial size used in the present invention is 80-100 mesh, and the straw powder modification regeneration ABS of this partial size can make its performance
It is excellent；Partial size is too big or too small, composition properties can be caused poor because of easy to reunite or other reasons.
Regeneration ABS moisture content < 4% used in the present invention, moisture content is high, and polypropylene is be easy to cause in extrusion process
Degradation, polypropene composition are easy to appear broken strip phenomenon during tie rod.
Isocyanates in the present invention plays the role of increasing regeneration ABS and straw powder compatibility.
ABS and decyl amide will be first regenerated in preparation process, first be turned/min mixing 2-5 minutes with 600-800；Suitable mixing
Time and speed, it is therefore an objective to so that decyl amide is sheared power friction overheat in mixing, fusing is uniformly adhered to regeneration ABS table
Face.It adds straw powder to turn/min mixing 2-5 minutes with 100-400, straw powder is adhered to regeneration by the decyl amide after making fusing
ABS particle surface.Wherein connection regeneration acrylonitrile-butadiene-styrene copolymer and " binder " of straw powder are exactly caprinoyl
Amine.Mixing velocity cannot be too fast, not so will lead to part straw powder " being burnt ".Then isocyanates and antioxidant 1- again is added
2min, this uniformly mixed material can store in a long time.It is used as binder if it is decyl amide is substituted with liquid,
It must then use, cannot be stored immediately in a short time.Last hot-forming, the purpose of hot pressing is to increase the plasticity of composition,
Evaporate the moisture in slab.
So the present invention utilize straw powder modification regeneration vinyl chloride composition, can not only make full use of regeneration vinyl chloride,
Straw powder turns waste into wealth, and can reduce cost with it, gives increasing peasant income, and the burning that can reduce straw powder causes environment
Pollution.Straw powder is adhered to regeneration chloride particles surface by decyl amide by the present invention, improves straw powder and regeneration chloroethene
Alkene compatibility is uniformly mixed them, improves the mechanical property of final products.
