Description
Technical field
The present invention relates to a kind of environment-friendly type PVC/ABS plastic alloy material and preparation method thereof.
Background technology
Polyvinyl chloride resin (PVC is the abbreviation of Polyvinyl Chloride) is a polarity amorphism superpolymer, and stronger reactive force is arranged between the molecule, is a hard and crisp material, and resistance to impact shock is lower.Chemical structural formula:
Its product has good physicals and chemical property, and physical appearance is a white powder, nontoxic, odorless.Relative density 1.35～1.46, specific refractory power 1.544 (20 ℃), water insoluble, gasoline, alcohol and vinylchlorid are dissolved in acetone, ethylene dichloride and dimethylbenzene equal solvent, and chemical stability is very high, has good plasticity-.Except that the minority organic solvent, the caustic soda below the hydrochloric acid that normal temperature down can anti-any concentration, the sulfuric acid 90% below, 50～60% the nitric acid and 20%, in addition, for also quite stable of salt; PVC can burn on flame and emit HCl, but leaves flame promptly from putting out, and is a kind of " self-extinguishing ", " flame retardancy " material; PVC is beginning decomposition more than 100 ℃ and slowly emitting HCl, and along with temperature rises, decomposition speeds up with release HCl, causes the PVC variable color.Polyvinyl chloride resin has obtained widely using with excellent chemical stability, electrical insulating property, flame retardant resistance, but its thermostability, shock resistance are poor.Polyvinyl chloride resin can be processed into various plastics, can be divided into soft and hard product two big classes by its purposes, be mainly used in and produce slide, pipe fitting, gold card, blood transfusion equipment, soft or hard pipe, sheet material, door and window, profiled material, film, electrically insulating material, cable sheath, blood transfusion material etc.
ABS resin (acrylonitrile-styrene-butadienecopolymer, ABS is the abbreviation of Acrylonitrile Butadiene Styrene) be a kind of intensity height, good toughness, be easy to thermoplastics type's terpolymer macromolecular material of machine-shaping, wherein, vinyl cyanide accounts for 15%～35%, divinyl accounts for 5%～30%, styrene comprise 40%～60%, modal ratio is A: B: S=20: 30: 50, this moment, the ABS resin fusing point was 175 ℃.The little Huang of outward appearance is opaque, and relative density 1.04 has good dimensional stability, outstanding shock-resistance, thermotolerance, dielectricity, wear resistance, and surface luster property is good, easily application and advantage such as painted.Chemical structural formula:
For simple polyvinyl chloride resin and ABS resin, its relevant goods have many deficiencies at aspect of performance, and the PVC/ABS alloy both had ABS resin shock-resistant, low temperature resistant, be easy to advantages such as forming process, have the flame retardant resistance of PVC and erosion resistance, weathering resistance, scrub resistance, advantage such as cheap again, thereby obtain a kind of alloy material of high performance-price ratio, can be applicable to industry-by-industries such as electronics, instrument, automobile, household electrical appliance, cable jacket.
Summary of the invention
One of purpose of the present invention is to provide a kind of environment-friendly type PVC/ABS plastic alloy material.This material has performances such as erosion resistance, weathering resistance, shock-resistant, low temperature resistant, fire-retardant, environmental protection.
Two of purpose of the present invention is to provide the preparation method of this plastic alloy material.
For achieving the above object, the present invention takes following technical scheme:
A kind of environment-friendly type PVC/ABS plastic alloy material is characterized in that the composition of this alloy material and quality percentage composition are:
Above-mentioned stablizer is a Ba/Zn class stablizer.
Above-mentioned Ba/Zn class stablizer is: barium stearate and Zinic stearas.
Above-mentioned lubricant is TC-60.
Above-mentioned softening agent is epoxidized vegetable oil softening agent such as Plasticizer Epoxidized Soybean Oil, epoxy linseed oil softening agent.
A kind of method for preparing above-mentioned environment-friendly type PVC/ABS plastic alloy material is characterized in that the concrete steps of this method are:
A. the polyvinyl chloride resin sealing is ground back and stablizer, the hot mixing of lubricant speed mixing machine, the blended temperature is 100-115 ℃, and hot mixing time is 10-15 minute;
B. step a gained mixture being added low speed cold mixer grinding sealing with ABS mixes;
C. in the step gained, add active calcium carbonate powder in the mixture, ground and mixed;
D. will add the twin screw extruder extruding pelletization in the step c gained mixture, the extrusion temperature of twin screw extruder is 140～190 ℃.
The present invention compared with prior art, have following outstanding feature and remarkable advantage: the present invention utilize the PVC/ABS polyblend of cleaning procedure production preparation both had ABS resin shock-resistant, low temperature resistant, be easy to advantage such as forming process, have the flame retardant resistance of PVC and erosion resistance, weathering resistance, scrub resistance, advantage such as cheap again, thereby obtain a kind of alloy material of high performance-price ratio, can be applicable to industry-by-industries such as electronics, instrument, automobile, household electrical appliance, cable jacket; The invention provides a kind of cleaner production preparation technology of the PVC/ABS of preparation polyblend, production technique of the present invention has increased the closed mechanical pulverizing mill technology of pulverizing, the implementation totally enclosed is produced, the pollution that solved dust, reduce the energy volatilization, save mixing time, realize zero release, do not have " three wastes " and pollute at utmost energy-saving and emission-reduction.
