Abstract
The present invention discloses original position bulking polystyrene/polyolefin elastomer blending alloy and preparing technology thereof. Polystyrene, polyolefin elastomer and a bulking agent are used as raw materials which are stirred for 10 to 20 minuters to be uniformly mixed according to weight parts, and the raw materials are transferred into a double screw extruder to be melted and extruded; a material cylinder has the temperature that the temperature of a material filling zone is 150 to 170 DEG, the temperature of a mixing zone is 165 to 185 DEG, the temperature of a reaction zone is 170 to 190 DEG, and the temperature of a die head is 160 to 180 DEG, the pressure of a machine head is 3 to 6MPa, and the raw materials are cooled and granulated after extruded to manufacture products with milky cylindrical particles. The preparing method of the alloy material of the present invention has the advantages of simplicity, low cost, easy recovery and good combination properties, wherein the toughness of the present invention is far higher than high impact-proof polystyrene, and the present invention can cleverly or partially substitute HIPS and ABS to be applied to some industrial places and has extensive market pprospect.
Description
Technical field
The present invention relates to the processing of macromolecular material or the technological process of batching, is a kind of original position bulk filling polystyrene/polyolefin elastomer blending alloy and preparation technology.
Background technology
(Polystyrene PS) is water white general-purpose plastics to polystyrene, and is cheap, has higher intensity and modulus and favorable manufacturability.But, limited its application greatly because its property is crisp.Polydiene commonly used and styrene monomer carry out copolymerization and make HIPS, ABS, have improved the toughness of polystyrene, have widened the Application Areas of polystyrene, and at present, HIPS and ABS have been widely used in industries such as electronics, electrical equipment, instrument, packing, daily necessities.But HIPS (high-impact polystyrene) and ABS (acrylonitrile-butadiene-styrene copolymer) they are that to utilize copolymerization to carry out toughness reinforcing, the complicated difficulty of technology controlling and process, and cost is higher, and is difficult to regulate immediately as required the toughness of material.
Summary of the invention
The purpose of this invention is to provide a kind of original position bulk filling polystyrene/polyolefin elastomer blending alloy and preparation technology of utilizing.
The technical solution used in the present invention is as follows:
One, original position bulk filling polystyrene/polyolefin elastomer blending alloy, composition of raw materials be by weight:
70～95 parts of polystyrene
5～30 parts of polyolefin elastomers
0.1～1.2 part of expanding material
Described polyolefin elastomer is ethylene-octene copolymer POE; Expanding material is an aluminum trichloride (anhydrous).
Two, original position bulk filling polystyrene/polyolefin elastomer blending alloy preparation technology:
Press 70～95 parts of polystyrene, ethene one octene copolymer POE5～30 part, 0.1～1.2 part of proportioning of aluminum trichloride (anhydrous) stirs 10～20min until mixing with stirrer, after change in the twin screw extruder and melt extrude, barrel temperature is 150～170 ℃ of packing areas, 165～185 ℃ of mixing zones, 170～190 ℃ of reaction zones, 160～180 ℃ of die head temperatures, head pressure 3～6MPa extrudes the product that postcooling, granulation can make the oyster white cylindrical pellet.
The useful effect that the present invention has is: it is toughner that the present invention adopts polyolefin elastomer (PolyolefinElastomer, POE, a kind of novel ethylene-octene copolymer).Compare with traditional elastic body toughening agent, use polyolefin elastomer, in toughness reinforcing, still can make material keep higher yield strength and good processing flowability.Need only be on twin screw extruder blended melting just extrude and can realize toughening modifying, technology controlling and process is simple, and can regulate the toughness of material as required immediately, has the characteristics of low-cost and high-performance.The reactivity of original position increase-volume is extruded blend method, and its used catalyzer is general and inexpensive reagent, and discarded PS is material modified to have a very big economic potential for recycling.The simply supported beam notched Izod impact strength, PS:0.8～1.5KJ/m
2, common HIPS:5～7KJ/m
2, common ABS:5～10KJ/m
2, and polystyrene alloy material of the present invention is 4.8～8.7KJ/m
2, not only near HIPS, also approach common ABS, be suitable for industrialization, have extensive market prospects.By the cost that the market present price is calculated, PS:11000～12000 yuan/ton, HIPS:12000～13800 yuan/ton, ABS:15000～17000 yuan/ton, the polystyrene alloy that the present invention makes～12800 yuan/ton.
