Shanghai Daoqin Plastics Co., Ltd.

        塑木 composite/compounding material as is types new type material, property can separation 体现 木材 and plastics advantages, 且不含甲 aldehyde formed separation, in outer widely used in outer construction material. due to thermoplastic property plastics and fiber is carbon hydrogen combined material, in 遇明火 or in add hot lower easy 燃烧, therefore WPC is type easy composite/compounding material, but also in process in generate a large amount of has gas 体, 因而限 made its use scope/range, therefore in production process in need add flame retardant. composite/compounding flame retardant and to for 木材组 separation flame retardant and for polymer flame retardant. polyolefin and flame retardant using/adopting machine flame retardant (hydrogen oxidation aluminum, hydrogen oxidation and other), flame retardant (十 bromine ether and other) and flame retardant (poly acid 铵, acid ester and other) and other product types, its in hydrogen oxidation and hydrogen oxidation aluminum and other machine flame retardant price low 廉, heat stabilized property excellent, tool has and and other advantages to 关注.

         experiment/testing material

        刨花树 types main/primary is 云南松 and 桉树, moisture content 5.8%. high density polyethylene (PE) (HDPE)粒 material, density is 0.941g/cm3~0.960g/cm3. industrial grade silicon coupling agent. separation understanding temperature degree 350℃. nano hydrogen oxidation aluminum (nano ATH), short direction 50-60nm, long direction 300-400nm. analysis pure non nano hydrogen oxidation aluminum (non nano ATH).

        仪 device equipment

         oxygen index (LOI) 测定仪, composite/compounding made 备.

        塑木复台材 塑木 ratio/proportion is 6:4, silicon coupling agent use amount is 2%. will plastics, 刨花, coupling agent flame retardant ratio in machine in separation mixed combined, 手工铺装 formed 305mmx350mm hydrophobic sheet/plate 坯. in room temperature lower 进行预 pressure (预 pressure pressure is IMPa, pressure 时问30s), rear 放八平 sheet/plate machine in hot pressure molding. composite/compounding 材名义 density setting is 0.89/cm3, thick degree 10xma. main/primary hot pressure parameters; hot pressure temperature degree 180℃. hot pressure time 12rain, hot pressure pressure 2MPa.

         property can testing

        塑木复台材 oxygen index (LOI) 按GB/T2406-1993进行 testing, 塑木复台材 force property can 参照《人造 sheet/plate and 饰面人造 sheet/plate property can experiment/testing methods GB/T17657.1999》进行 testing.

         flame retardant types type for WPc oxygen index (LOI) effect/influence.

        图1 using/adopting 5 types flame retardant, its in l代 table/sheet nano MH, Ⅱ代 table/sheet nano ATH, Ⅲ代 table/sheet non nano ATH, IV代 table/sheet nano ATH+ nano MH(ratio/proportion 1:1), V代 table/sheet nano ATn+ non nano ATH(ratio 倒1:1), flame retardant use amount is 12%.

        图1 add different flame retardant 复台材 material oxygen index (LOI).

        图1 can 见: nano flame retardant need ratio non nano flame retardant flame retardant property can good; mono use nano MH and ATH, nano ATH need good nano MH; nano MH and nano ATH mixed combined use, can generate 协同效应; nano ATH and non nano ATH mixed use, generate 反协同效应. this is is nano pellets pellets small, ratio surface large, add upper nano pellets dimensions and surface 效应. increase flame retardant and between 接触面积, reinforcement flame retardant and interface versus function and hydrophilic and property, improvement versus property;MH and ATH absorption hot amount separation is 1.42MJ/kg, 1.2 MJ/kg, but also MH hot separation understanding temperature degree high, upper is nano MH flame retardant need ratio nano ATH good, 而本实验出现 nano ATH need good nano MH, this is due to 两者不 is company product, is nano grade, dimensions also is in 差异, this effect/influence its flame retardant 效果.
