         poly ether is type chemical structure in has aromatic non polymer, is specialty engineering plastics in important product types. currently, already 经商业化 poly ether main/primary has product types, di 酚A type polysulfone (PSU) (PSU), polyether 砜(PES) and poly 亚苯基砜(PPSU). poly ether tool has excellent force property can, electrical property can, heat resistant property, flame retardant property, creep resistance and chemical stability property, in electronics electrical, automotive, medical and use food and other field/area inner obtain application. and PSU and PES versus ratio, PPSU most features is its tool has more good resistant impact property can, meanwhile resistant water and 蒸汽反复消毒, therefore PPSU也 by widely used in 婴儿奶 bottle, food container and other field/area.

         for/regarding PPSU modified material, currently research main/primary in in filling modified and alloy 化两 方面. and other through solvent liquid blending method made PPSU/石墨烯 nano composite/compounding material, 并发现 add a small amount of 石墨烯便 can significantly improves PPSU force property can and conductive property. system research PPSU/ polyphenylene sulfide (PPS) alloy property can, research 显示, polyphenylene sulfide (PPS) can significantly improvement alloy resistant solvent agent property and water property, meanwhile PPSU良 good force property can improvement polyphenylene sulfide (PPS) resistant impact property can features.

         in application process in, use glass fiber (GF) reinforcement methods is currently modified poly ether product most use methods. for/regarding pure resin material, PSU and PES 悬臂梁 notched impact strength separation is 5.5 kJ/m2 and 7.5 kJ/m2, 而PPSU notched impact strength can to 55 kJ/m2; pure PPSU resin performance excellent impact tough property. however, 以30% GF reinforcement product is 例, PPSU/GF composite/compounding material 悬臂梁 notched impact strength and PSU/GF and PES/GF composite/compounding material 接近, in 7～9 kJ/m2. in GF modified composite/compounding material in, PPSU excellent impact property can difficult 以体现, this and GF and PPSU基体 between interface combined function has 关. is, has 关GF reinforcement PPSU材 material research relatively less, its toughened methods has research as and. therefore, is research PPSU/GF composite/compounding material tough property improves methods and improves GF and PPSU基体 between interface combined function, through melt blending methods in GF reinforcement PPSU composite/compounding material in high temperature resistance maleic anhydride grafted ethylene – acrylic ester copolymer (EBA-g-MAH) toughening agent (hot separation understanding temperature degree >400℃), improvement material force property can. research 结果显示, toughening agent can significantly improves GF reinforcement PPSU composite/compounding material notched impact strength, meanwhile improvement GF and between interface property can. this methods is 进一步 improvement GF reinforcement poly ether composite/compounding material property can, wide material application provide new 思路.

        1, use main/primary Raw Materials

        PPSU: Visulfon B002 NC001, Kingfa corporation has company;

         short 切GF: 直径13 μm, heavy 庆国际 composite/compounding material has company;

        EBA-g-MAH: 1400MN, Germany can ratio company.

        2, sample made 备

         will PPSU resin ratio/proportion and toughening agent EBA-g-MAH预先 in high speed mixed combined machine in uniform mixed combined, mixed combined material and quality separation 数30% short 切GF in di screw extrusion machine in melt blending, water cooling rear pelletizing, to GF reinforcement PPSU composite/compounding material pellets (composite/compounding material ratio formed 以PPSU/GF/Ta table/sheet 示, separation table/sheet PPSU基体 resin, GF and toughening agent content). its in, extrusion screw speed is 300 r/min, processing temperature degree is 300～360℃. pellets material injection molding machine in 330~360℃ based on ISO standards injection molding formed strip/profile used for force property can testing.

        3, material property can summary

         through made toughening agent content separation is 0%, 5%, 10%, 15% and 20% GF reinforcement PPSU composite/compounding material, system research toughening agent for material property can effect/influence, 结论如 lower:

        (1)随 toughening agent content increase, composite/compounding material strong/high degree, elastic property elastic property modulus and density obvious reduce;当 toughening agent content is 5%时, can has improves material degree;当 toughening agent content is 20%时, material notched impact strength improves 67%, tough property obvious improves.

        (2) and add toughening agent composite/compounding material versus ratio, toughening agent 引入会造 formed composite/compounding material separation understanding temperature degree reduce; toughening agent content is 20%时, composite/compounding material hot separation understanding temperature degree 由541℃ reduce 至455℃, material heat stabilized property decline.

        (3)随 toughening agent content increase, GF and between interface combined function reinforcement, material bad methods 发生变化, tough property improves.

        (4) in same processing process conditions lower, and add toughening agent composite/compounding material versus ratio, add toughening agent can has improves system in GF long degree; toughening agent content is 20%时, GF 数均保留 long degree 由370 μm improves 至510 μm, is GF distribution more add dispersion.
