         nylon 6 (PA6) its output/production volume relatively large, price low 廉, is most commonly used engineering plastics 之一, in nylon in tool has light heavy 位. PA6 tool has relatively good strong/high degree, rigid property, resistant thermal properties;同样 due to its property relatively strong/high, its water absorption relatively large impact tough property relatively 差, meanwhile water absorption large effect/influence, its dimensional stability and insulation property can relatively 差. ultra-high molecular weight polyethylene (PE) (PE-UHMW), is types separation tool has type structure molecular weight high 达150万 above thermoplastic property engineering plastics, tool has polyethylene (PE) and its it engineering plastics can ratio wear resistant, resistant impact, lubricated, corrosion resistant, low temperature resistance, 卫生无毒, easy viscous 附, easy water, density relatively small and other comprehensive property can; but also price in, in various plastics advantages, currently also has types mono pure polymer/macromolecule material has 如此众 more excellent property can. PA6 and PE-UHMW blending modified made alloy, tool PA6 and PE-UHMW features, can has improvement PA6 disadvantages, more year is plastics modified research focus/key point.

         is understanding PA6/PE-UHMW alloy property can, 山东东辰瑞森 new material has company 以PA6 is 第一主份, PE-UHMW is 第二主份, utilizing blending modified methods made PA6/PE-UHMW alloy, for its related property can research. PA6 is property material 而PE-UHMW is non property material, versus property relatively 差, therefore made alloy 时, add related increase agent increase 容. 山东东辰瑞森 new material has company research polyolefin grafting acid elastomer (POE-g-MAH), polyethylene (PE) grafting acid 酐(PE-g-MAH) this types increase agent for PA6/PE-UHMW alloy material property can effect/influence; its 次, selection PE-g-MAH as is increase agent, through add different content PE-g-MAH for PA6, PE-UHMW进行 increase 容, research PE-g-MAH添 add amount for PA6/PE-UHMW alloy property can effect/influence; most rear, selection add 10份PE-g-MAH for PA6, PE-UHMW different ratio alloy increase 容, research PE-UHMW content for PA6/PE-UHMW alloy property can effect/influence.

        01, different increase agent for PA6／PE-UHMW alloy property can effect/influence

        经 research to, alloy in PE-UHMW由20份 increase large to 40份时, alloy material tough property has different degree improve/increase, strong/high degree, flow property, heat resistant property has different degree reduce.

        添 add PE-g-MAH alloy material relatively add POE-g-MAH alloy remove notched impact strength relatively low, MFR versus outer its it property can relatively high. 当PE-UHMW由20份变 is 40份时, add 10份 different type type increase agent POE-g-MAH, PE-g-MAH alloy property can specific is: add POE-g –MAH时, alloy tensile strength, flexural strength, bending elastic property modulus, MFR, soft reduce degree separation is 19.1%, 36.4%, 31.9%, 92.9%, 26.3%, fracture elongation, notched impact strength improve/increase degree separation is 91.4%, 57.2%;添 add PE-g-MAH时, alloy tensile strength, flexural strength, bending elastic property modulus, MFR, soft reduce degree separation is 16.6%, 29.5%, 24.8%, 91.1%, 15.9%, fracture elongation, notched impact strength improve/increase degree separation is 49.1%, 24.6%.

        02, increase agent content for PA6／PE-UHMW alloy property can effect/influence

        经 research 发现, 当PA6 is 70份, PE-UHMW and PE-g-MAH均 is 15份即PE-UHMW, PE-g-MAH quality ratio is 1∶1时, alloy comprehensive property can relatively good. alloy in PE-UHMW and PE-g-MAH in ethylene mono amount versus 当, PE-UHMW and PE-g-MAH can relatively separation and PA6紧密结 combined, alloy formed is relatively is 均一结实 overall, make alloy material comprehensive property can relatively good. alloy notched impact strength is 17.3 kJ/m2, fracture elongation is 166.1%, tensile strength is 44.3 MPa, flexural strength is 55.0 MPa, MFR is 0.15 g/10 min, soft is 136.9℃.

        03, PE-UHMW添 add amount for PA6／PE-UHMW alloy property can effect/influence

        经 research 发现, 当PE-UHMW content 由0份 increase 至40份时, PA6/PE-UHMW alloy tensile strength, flexural strength, soft 化点, water absorption large decline trend, notched impact strength upper rise trend, fracture elongation 变化呈现先 upper rise rear decline again upper rise most rear basic trend. 当PE-UHMW content and PE-g-MAH一样 is 10份时, alloy tool has relatively good comprehensive property can, notched impact strength is 12.8 kJ/m2, fracture elongation is 162.9%, tensile strength is 50.7 MPa, flexural strength is 56.7 MPa, water absorption is 1.65%, soft is 155.8℃.

        该材 material can used for pipe/tube and sheet/plate 材.
