Abstract
The invention discloses recycled ABS plastic reinforced and toughened by adopting a micro-crosslinking method and a preparation method thereof. The preparation method comprises the following steps: drying the recycled ABS plastic in an air blowing manner for 6-8 hours at the temperature of 80 DEG C; weighing the dried recycled ABS plastic, a toughening agent, a cross-linking agent, a compatilizer and an inorganic filler according to a weight ratio, mixing in a high-speed mixer for 4-6 minutes, extruding and pelleting at the temperature of 190-220 DEG C by adopting a double-screw extruder to obtain a product. A conventional recycling method is used for toughening the recycled ABS plastic by adding an elastomer toughening agent, and generally the stretch performance of the recycled ABS material is reduced, and the overall mechanical properties are affected further; the technical scheme provided by the invention can be used for simultaneously reinforcing and toughening the recycled ABS plastic and has a quite high market promotion value.
Description
Technical field
The present invention relates to plastic material art, refer in particular to micro-crosslinking and strengthen toughness reinforcing recovery ABS plastic and preparation method thereof.
Background technology
ABS resin is vinyl cyanide, divinyl and styrol copolymer (Acrylonitrile-Butadiene
-Styrene) abbreviation or abbreviation.ABS resin is that a kind of intensity is high, good toughness, be easy to the thermoplastic macromolecule material of machine-shaping, be widely used in automotive industry, mechanical industry and electrical instrumentation industry, as gear, blade, panel board, casing, mud guard, handrail, safety helmet and all kinds of suitcase etc.
ABS is widely used in terminal consumption product, correspondingly also has a large amount of recuperable ABS resin, and along with the increasingly stringent of shortage and the environment protection of petroleum resources, the application of regeneration ABS resin progressively increases.Because market competition is extremely fierce, a lot of ABS production of articles commercial city starts to adopt regeneration ABS to expect to reduce costs.Yet reclaim ABS resin because of solarization, its mechanical property especially erosion-resisting characteristics can not show a candle to ABS virgin material, need to carry out can again utilizing after modification.
Chinese patent CN101016401 has proposed ABS plastic in use can cause because of the photoaging of divinyl segment the loss of rubber phase, the reduction of molecular weight and being separated, thus cause the reduction of mechanical property.By increasing the method for elastic body toughening agent, improve its impact property, increase inorganic nano temper improves Young's modulus and the heat-drawn wire of resin in the time of toughness reinforcing, add superoxide, light stability to improve its long greenhouse.Do not have the clear and definite method that clearly proposition improves the tensile strength of ABS feed back.
CN102634161A has proposed to improve the method that reclaims ABS plastic mechanical property, paintable energy, improves the shock strength of ABS feed back etc., but do not propose the clear and definite method that clear and definite method is improved the tensile strength of ABS feed back by toughner.
Summary of the invention
In view of this, the present invention is directed to the disappearance of prior art existence, its main purpose is to provide with micro-crosslinking and strengthens toughness reinforcing recovery ABS plastic and preparation method thereof.
For achieving the above object, the present invention adopts following technical scheme: with micro-crosslinking, strengthen toughness reinforcing recovery ABS plastic, by quality weight part, include:
Reclaim 60～80 parts of ABS plastic;
10～30 parts of toughner;
1～6 part of compatilizer;
0.1～1 part of linking agent;
5～10 parts of mineral fillers
Described toughner is at least one in ABS high glue powder, SEBS, SBS.
Described compatilizer is a kind of of maleic anhydride stem grafting polyolefin PP-g-MAH, PE-g-MAH, and percentage of grafting >=10% of maleic anhydride.
Described linking agent is at least one in benzoyl peroxide (BPO), di-isopropylbenzene hydroperoxide (DBHP).
Described filler is at least one in calcium carbonate, talcum powder, wollastonite, barium sulfate, kaolin.
The micro-crosslinking of use strengthens a preparation method for toughness reinforcing recovery ABS plastic, comprises the following steps:
A, will reclaim ABS plastic forced air drying 6～8 hours under 80 ℃ of conditions;
B, above material is put into high-speed mixer high speed by weight ratio and mixed 4～6 minutes, it is evenly mixed;
C, the material mixing is joined in twin screw extruder hopper, carry out melting mixing, extrude in high-speed mixer.
The extruder temperature of described twin screw extruder is controlled between 190 ℃-220 ℃.
The present invention compared with prior art has obvious advantage and beneficial effect, defect for prior art, present method is by micro-crosslinking technological, can in toughness reinforcing, realize the effect strengthening, the problem of solution because using elastic body toughening to cause tensile strength to decline, the ABS plastic that makes to regenerate has good whole mechanical property, thereby can reuse.
