Description
技术领域technical field
本发明涉及高分子材料的处理或配料的工艺过程，是一种原位增容聚苯乙烯/聚烯烃弹性体共混合金及制备工艺。The invention relates to a process for processing or batching polymer materials, and relates to an in-situ compatibilized polystyrene/polyolefin elastomer blended alloy and a preparation process.
背景技术Background technique
聚苯乙烯(Polystyrene，PS)是无色透明的通用塑料，价格低廉，具有较高的强度和模量和良好的工艺性。但由于其性脆，大大限制了其应用。常用二烯类橡胶与苯乙烯单体进行共聚制得HIPS、ABS，改善了聚苯乙烯的韧性，拓宽了聚苯乙烯的应用领域，目前，HIPS和ABS已广泛用于电子、电器、仪表、包装、日用品等行业。但是，HIPS(高抗冲聚苯乙烯)和ABS(丙烯腈-丁二烯-苯乙烯共聚物)都是利用共聚合反应进行增韧，工艺控制复杂困难，成本较高，而且难以根据需要即时调节材料的韧性。Polystyrene (Polystyrene, PS) is a colorless and transparent general-purpose plastic with low price, high strength and modulus and good manufacturability. However, its application is greatly limited due to its brittleness. Commonly used diene rubber and styrene monomer are copolymerized to obtain HIPS and ABS, which improves the toughness of polystyrene and broadens the application fields of polystyrene. At present, HIPS and ABS have been widely used in electronics, electrical appliances, instruments, Packaging, daily necessities and other industries. However, both HIPS (high impact polystyrene) and ABS (acrylonitrile-butadiene-styrene copolymer) are toughened by copolymerization, the process control is complicated and difficult, the cost is high, and it is difficult to instant Adjusts the toughness of the material.
发明内容Contents of the invention
本发明的目的是提供一种利用原位增容聚苯乙烯/聚烯烃弹性体共混合金及制备工艺。The object of the present invention is to provide a polystyrene/polyolefin elastomer blended alloy utilizing in-situ compatibilization and a preparation process.
本发明采用的技术方案如下：The technical scheme that the present invention adopts is as follows:
一、原位增容聚苯乙烯/聚烯烃弹性体共混合金，原料配方按重量份数：1. In situ compatibilized polystyrene/polyolefin elastomer blended alloy, the raw material formula is in parts by weight:
聚苯乙烯 70～95份Polystyrene 70～95 parts
聚烯烃弹性体 5～30份Polyolefin elastomer 5～30 parts
增容剂 0.1～1.2份Compatibilizer 0.1～1.2 parts
所述的聚烯烃弹性体为乙烯-辛烯共聚物POE；增容剂为无水三氯化铝。The polyolefin elastomer is ethylene-octene copolymer POE; the compatibilizer is anhydrous aluminum trichloride.
二、原位增容聚苯乙烯/聚烯烃弹性体共混合金制备工艺：2. Preparation process of in-situ compatibilized polystyrene/polyolefin elastomer blend alloy:
按聚苯乙烯70～95份，乙烯一辛烯共聚物POE5～30份，无水三氯化铝0.1～1.2份配比，用搅拌机搅拌10～20min直至混匀，后转入双螺杆挤出机中熔融挤出，料筒温度为填料区150～170℃，混合区165～185℃，反应区170～190℃，模头温度160～180℃，机头压力3～6MPa，挤出后冷却、造粒即可制得乳白色圆柱状颗粒的产品。According to the ratio of 70-95 parts of polystyrene, 5-30 parts of ethylene-octene copolymer POE, and 0.1-1.2 parts of anhydrous aluminum trichloride, stir with a mixer for 10-20 minutes until evenly mixed, and then transfer to twin-screw extrusion Melt extrusion in the machine, the barrel temperature is 150-170°C in the filler area, 165-185°C in the mixing area, 170-190°C in the reaction area, 160-180°C in the die head temperature, 3-6MPa in the head pressure, cooling after extrusion , Granulation can produce milky white cylindrical granule products.
本发明具有的有益的效果是：本发明采用聚烯烃弹性体(PolyolefinElastomer，POE，一种新型的乙烯-辛烯共聚物)为增韧剂。与传统的弹性体增韧剂相比，使用聚烯烃弹性体，在增韧的同时，尚可使材料保持较高的屈服强度及良好的加工流动性。只须在双螺杆挤出机上共混熔融挤出就可实现增韧改性，工艺控制简单，而且可以根据需要即时调节材料的韧性，具有低成本高性能的特点。原位增容的反应性挤出共混方法，其所用的催化剂是通用而价廉的试剂，对于回收利用废弃PS改性材料具有很大的经济潜力。简支梁缺口冲击强度，PS：0.8～1.5KJ/m2，普通HIPS：5～7KJ/m2，普通ABS：5～10KJ/m2，而本发明的聚苯乙烯合金材料为4.8～8.7KJ/m2，不仅接近HIPS，也接近于普通的ABS，适于工业化，具有广泛的市场前景。按市场现价计算的成本，PS：11000～12000元/吨，HIPS：12000～13800元/吨，ABS：15000～17000元/吨，本发明制得的聚苯乙烯合金～12800元/吨。The beneficial effect of the present invention is that: the present invention uses polyolefin elastomer (Polyolefin Elastomer, POE, a novel ethylene-octene copolymer) as a toughening agent. Compared with the traditional elastomer toughening agent, the use of polyolefin elastomer can make the material maintain a high yield strength and good processing fluidity while being toughened. Toughening and modification can be realized only by blending and melting extrusion on a twin-screw extruder, the process control is simple, and the toughness of the material can be adjusted in real time according to needs, which has the characteristics of low cost and high performance. The reactive extrusion blending method of in situ compatibilization, the catalyst used is a common and cheap reagent, which has great economic potential for recycling waste PS modified materials. Charpy notched impact strength, PS: 0.8-1.5KJ/m 2 , ordinary HIPS: 5-7KJ/m 2 , ordinary ABS: 5-10KJ/m 2 , and the polystyrene alloy material of the present invention is 4.8-8.7 KJ/m 2 is not only close to HIPS, but also close to ordinary ABS, suitable for industrialization, and has broad market prospects. According to the current market price, PS: 11,000-12,000 yuan/ton, HIPS: 12,000-13,800 yuan/ton, ABS: 15,000-17,000 yuan/ton, and the polystyrene alloy prepared by the present invention is 12,800 yuan/ton.
