Shanghai Daoqin Plastics Co., Ltd.

         full year has automotive 自燃事故发生. according to 公开资 material 显示, 2016 year inner 共发生29起约40辆 new can automotive 起火事故, its in, pure electric vehicles is 起火事故 high 发 车辆 type type, ratio high 达79%; its is electrical mixed combined force ratio 10%, electrical mixed combined force 7%, most rear 未披露动 force type type 占4%. that 么, new can automotive how to good anti flame retardant 呢?

         new can automotive difference 于燃油车 方 in electrical as is 驱动动 force 源. therefore use electrical safety 显 尤 is important. 一旦发生 electrical short or high pressure 击穿, 就会导致零部 parts 停止工 as, light 则导致 automotive 抛锚, 整车漏 electrical, heavy can can 会引起 automotive 自燃. new can automotive in material selection upper remove insulation resistant pressure, anti 腐蚀, also need flame retardant property. 今天, to large simple introduction lower currently new can automotive market upper different parts large separation main/primary flame retardant material.

        1, battery 模组

         currently, world 各国没 has 统一 车 use electrical pressure standards, large new can automotive enterprise using/adopting electrical pressure has different. similar ratio Di this 样 车企 using/adopting low, in, high more electrical pressure new energy vehicles, high pressure electrical pressure can 达690V, 而瞬间脉冲 can 达800V above. therefore, if using/adopting flame retardant material, electrical pressure or high temperature, can 导致整车漏 electrical or and other 事故. therefore, flame retardant material formed is battery 模组 包 housing/shell 首选.

         battery pack housing/shell generally can using/adopting: 铸造钢 sheet/plate, aluminum alloy, SMC composite/compounding material, carbon fiber reinforced composite/compounding material, long glass fiber (GF) flame retardant reinforcement polypropylene (PP) material, PP-LGF35 and other.

        SMC composite/compounding material, sheet/slice plastics. main/primary 由GF(specialized 纱), UP(不 saturated and resin), low shrinkage additives, MD(filler) and various additives formed. plastics housing/shell tool has relatively good cost advantages and comprehensive property can, is currently development force battery housing/shell main/primary development material. in for force battery 提出 明确 flame retardant requirements rear, 越 越 more enterprise in electrical, 博世, and other, using/adopting flame retardant plastics battery housing/shell 体.

        2, electrical 设施

        充 electrical standards currently 也尚不完 full 一致. due to different electric vehicles electrical pressure different, again add upper 接口, agreement and other technology factors different, this 直接导致 桩 and between can 互联互通, but also 车桩不匹配 issues non 常突出. electrical 设施包括 charging stations, high pressure 线, high pressure parts and electrical and other high pressure parts. its important property and inner force battery 一样, need 考虑充 electrical flame retardant property, safety property and other 方面. according to currently inner published electrical standards and requirements, for charging stations and electrical outer housing/shell, base/seat 插头以 and internal high pressure flame retardant material 进行 整理, 并列举 currently electrical product, for versus 应 材 material property can features analysis.

        3, electrical appliances parts

         electrical appliances parts electrical appliances, high pressure parts and other need add flame retardant material, this is basic requirements. parts metal need 插拔次数 more, also requirements lifespan need long, aging fracture heat resistant. currently Common material main/primary has PBT, PA and other material.

         according to this requirements, inventory/review separation Common material and its for 应 一 材 material features lower 图 示.

        车 use flame retardant material future

        我国 in high poly material (various plastics engineering plastics) flame retardant in, main/primary is use amount less, flame retardant efficiency high 且适应 property 广 添 add type bromine flame retardant is 主. bromine in more bromine ether (PBD PO) in 燃烧时会 generate has 毒致癌 more bromine 代苯并烷(PBDD) and more bromine 代苯并呋喃(PBDF), but also flame retardant in 燃烧时生 formed a large amount of and has tool property gas 体, can mono pure 由火 不 can electrical system and its it metal material parts and for 人体呼吸道 and its it device formed 危害 严 heavy disadvantages.

         currently 我国也 in for automotive inner trim parts made new anti standards, 意见稿 already 经发出, in 保留GB8410 基础 upper, increase 垂直燃烧, oxygen index (LOI), density and other several indicators. increase density indicators is very large 进步, 火灾发生时, more is by gas 窒息而死. is, still has 考虑烟 gas property.

        人们 day heavy environmental protection, safety, issues, 各国也 environmental protection type flame retardant material as is focus/key point development and research for 象. standards 也会愈 add and 严格, 随之而 is, use flame retardant material environmental protection and more direction development.
