         flame retardant technology 目 就 is let non flame retardant material tool has flame retardant property can, in conditions lower easy or can self-extinguishing, is types provide safety 保障 材 material. future flame retardant development direction is flame retardant good, safety more environmental protection. is 此投入 versus large force and 资源进行 flame retardant new technology R&D. 现如今 说, versus R&D 出 几项 flame retardant new technology. small lower need is large introduction environmental protection flame retardant new type flame retardant technology.

        一, surface modified

        无 machine flame retardant tool has relatively strong/high property and hydrophilic water property, non property polymer material versus property 差, interface difficult formed good combined and bonding. is improvement its and polymer bonding force and interface hydrophilic and property, using/adopting agent for its surface treatment is most is has methods 之一. commonly used coupling agent is silicon and titanium acid ester type. silicon 烷处理 rear ATH flame retardant good, can has improve/increase polyester flexural strength and ring oxygen resin tensile strength;经 ethylene - silicon 烷处理 A TH can used for improve/increase crosslinked ethylene-vinyl acetate (EVA) copolymer flame retardant property, heat resistant property and resistant wet property. titanium acid ester type coupling agent and silicon coupling agent can use, can generate 协同效应. surface modified rear ATH surface active property to improve/increase, reinforcement and resin between hydrophilic and force, improvement products material mechanical properties, increase resin processing flow property, reduce A TH surface wet rate, improve/increase flame retardant products various electrical properties, will flame retardant 效果由 V21 grade improve/increase to V20 grade.

        二, ultra- fine 化

        无 machine flame retardant tool has stability property high, easy 挥发, gas property low, cost low and other advantages, 越 越受 to 人们 青睐. its and combined formed material versus property relatively 差, add amount large, make material force property can and resistant thermal properties has reduce. therefore, for machine flame retardant modified, reinforcement its and combined formed material versus property, reduce its use amount formed is machine flame retardant development trend 之一. currently, hydrogen oxidation aluminum (3 Al(OH)) ultra- fine 化, nano is main/primary research development direction. 3 Al(OH) a large amount of add reduce material machine property can, through for 3 Al(OH) micro fine again filling, 反而会起 to rigid property pellets increase 塑, reinforcement 效果, especially is nano grade material. due to flame retardant function is chemical reaction 支配, and other amount flame retardant its 粒径愈 small, ratio surface 积就愈 large, flame retardant 效果就愈 good. ultra- fine is from hydrophilic and property 方面考虑. positive is due to hydrogen oxidation aluminum and polymer property different, 才导致 its flame retardant type composite/compounding material material mechanical properties decline. ultra- fine nano 化 3 Al(OH) reinforcement interface versus function, can uniform dispersion in resin in, more has improvement blending material force property can.

        三, 复配协同

         in production application in, mono flame retardant in this or that defect, but also use mono flame retardant very difficult meet/satisfy 越 越 high requirements. flame retardant technology is in 磷系, 卤系, nitrogen and machine flame retardant between, or certain type internal composite/compounding 化, most 佳 经济 and 社会效益. flame retardant technology can comprehensive types or types above flame retardant long 处, make its property can 互补, to reduce flame retardant use amount, improve/increase material flame retardant property can, processing properties and material mechanical properties and other 目.

        四, crosslinked

         crosslinked high poly material flame retardant property can ratio type high poly material good more. in thermoplastic property plastics processing add a small amount of crosslinked agent, can make plastics formed separation structure, can improvement flame retardant dispersion property, has plastics 燃烧时 generate function, improve/increase flame retardant property can, can increase products machine 械, heat resistant and other property can.

        五, micro 胶囊化

         will micro 胶囊化应 used for flame retardant is in recent years development 起 一项 new technology. micro 胶囊化 实质 is flame retardant powder dispersion formed micro 粒, use has machine material or machine material 进行包囊, formed micro flame retardant, or surface very large machine material is 载体, will flame retardant in this machine material 载体 空隙 in, formed 蜂窝式 micro flame retardant. bromine type environmental protection flame retardant micro 胶囊化 has below/following advantages: can improvement flame retardant stability property; can improvement flame retardant and resin versus property, make material material mechanical properties reduce phenomenon improvement; can large large improvement flame retardant multiple property can, expand large its application scope.

        六, nano flame retardant technology

         has nano material tool has retardant 止燃烧 function, will it as is flame retardant add to can material in, utilizing its dimensions and structure 效应, can can material property can, make formed is tool has anti property can material. utilizing nano technology can flame retardant mechanism, improve/increase flame retardant property can. due to nano pellets pellets dimensions very small, ratio surface very large, it performance surface 效应, 体积效应, amount dimensions and macro amount 子隧道效应 and other 特征, is design and made high property can, more function new material provide new and 途径.

         above types technology is most new flame retardant technology research formed 果, detailed in will, has more more technology application to flame retardant product in, is large provide more add safety active ring 境.
