PPO separation structure 式

一.国 outer PPO development history

1959 year, USA GE company PPO; 1966 year, GE rate will PPO and PS blending modified formed 功, rear modified PPO to fast speed development and application; 1979 year, Asahi Kasei using/adopting styrene grafting method production modified PPO, from 而打破 GE 垄断; to 80 year 代, due to GE company patent to 期, BASF, Mitsubishi, Sumitomo chemical and other chemical industry 巨头纷纷进入 to PPO field/area.

二.PPO advantages （ and other engineering plastics versus comparison ）

PPO tool has other engineering plastics method ratio property can advantages, main/primary has: resistant solvent agent, flame retardant property can good, dimensions stability, specific gravity most light, water most small, electrical strong/high degree most high, high heat resistant and other. lower specific 看看:

1. specific gravity most light

in more engineering plastics in, PPO density most light, is 1.06g/cm³; 故PPO can most large degree achieve product light amount 化!

2. water absorption most low

PPO significantly features is water absorption low. this make PPO in wet conditions lower, dimensional stability and mechanical properties decline large, non combined outer use.

3.介 electrical strong/high degree most strong/high

in vast temperature degree and frequency rate lower, PPO can maintain excellent electrical property can; 因而广泛 application in electronics electrical appliances field/area.

4.玻璃化转变 temperature degree most high

PPO玻璃化转变 temperature degree can to 200℃, in long temperature degree relatively high conditions lower, force property can 变化不 large.

但 is, PPO melt flow property 差, thermoplastic processing difficult. 几乎不 can mono 独进行 extrusion and injection molding processing. is meet/satisfy multiple applications need, for PPO进行 series modified already is can less.

三.PPO alloy and its application

1．PPO／HIPS(PS)

PPO／HIPS(PS) is most by development 出 一 modified PPO, rigid already to is USA GE首先推 toward market. PPO／HIPS(PS) tool has 令人满意 appearance, good tough property and processing property, PPO／HIPS(PS) basic material property ratio 关系 变化而变化, in 我们 实验 series process in 发现, use Domestic PPO can hot deformation (1.86MPA)120℃ above, meanwhile impact can to 20KJ／m2 above. in product color control 方面, need comparison excellent additives combined use, basic can to ABS color. PPO／HIPS(PS) application has:

ppo/ps材质 products

home appliances products: 剃 must 刀, electrical 熨斗, device, powder machine, electrical 冰箱, and other.

medical field/area: can used for resistant 射线消毒 and solvent agent equipment, outer use tool and medical 检查仪 device.

its it application areas: can used for manufacturing office furniture, base/seat 椅, 扶手; can used for production automotive, shipbuilding, use parts and other.

its application areas also in 不断 拓展壮 large in, in will, its product is in 我们生 active 各 角落.

2．PPO／PA

this type of alloy is crystallization and non crystallization non versus property alloy. its in molding processing rear property can obtain very large improvement, PPO／PA alloy utilizing advantages 互补, has advantages, using/adopting most new versus property technology and mixed technology made formed series alloy product types tool has excellent comprehensive property can. its heat deflection temperature (HDT) high, dimensional stability good, tool has very high degree, in low temperature lower still has very high tough property, chemical resistant product property and good processing property. its field/area has:

electronics electrical field/area: can used for production electronics electrical appliances product, use electrical appliances and 键盘, light 盘, true 通讯, magnetic belt/tape, machine and other precision parts.

PPO/PA材质 automotive sheet/plate, 源: Kumho day 丽

automotive made parts: PPO／PA series product suitable for automotive made parts, used for production automotive large type sheet/plate, automotive trim parts; automotive upper 垂直部 parts, 如挡泥 sheet/plate and 车门, device, dispersion hot device 格栅, 车轮护 cover/cap table/sheet 盘, 车身垂直 plastics outer sheet/plate, 车轮罩 and other various sheet/plate and other.

chemical industry industry: can used for chemical industry 泵, 阀门, gears, high pressure container and other, its flame retardant grade already can meet/satisfy electronics electrical use requirements. PPO／PA alloy tool has excellent comprehensive property can, its series product can and nylon product competition, can meet/satisfy electronics electrical parts use requirements, can used for use electrical appliances, electronics electrical and office equipment housing/shell 体键盘, various parts, sheet/plate and used for made as automotive table/sheet 盘, 车身垂直 plastics outer sheet/plate, 车轮罩 and other various 护罩, sheet/plate.

currently 我国PPO／PA alloy product 起步晚, Domestic PPO原 powder property can unstable, but also property can generally, especially is PPO／PA alloy system compatibilizer heavy 缺乏, this is effect/influence 我国该 alloy high speed development main/primary causes, 我们必 must use more 方面共同进步, improve/increase technology water 平, to world high water 平. currently material basic material property is: tensile strength 55MPA left right, flexural strength 100MPA left right, flexural modulus 2500, notched impact strength 50KJ/m2.

3． flame retardant PPO

随 world for flame retardant material add heavy 视, 各 材 material for flame retardant property 改进也 in 轰轰烈烈 进行 in, due to PPO本身就 has flame retardant property, generally need add a small amount of flame retardant can to good flame retardant 效果, generally 说, flame retardant has: RDP, BDP, TPP, and other.

无卤 flame retardant PPO应 used for photovoltaic connectors

原 USA GE company 9406就 is very type product, it tool has good flame retardant property, processing property, degree mechanical properties, already by application in for resistant temperature requirements non high products.

4．PPO cable material

this main/primary is utilizing PPO良 good resistant temperature property and other mechanical properties, PPO cable material tensile strength can very 完美 达 to 20MPa left right, is polyolefin cable material 近一倍 more, but also also tool has good resistant temperature property, can in ring lower long use

5．PPO／PP

PPO／PP most is USA GE company development, its and PPO／PA一样, through advantages 互补, long short. currently product in inner slow slow 逐步兴起, less company 也应该 in development process in, especially is has force large company.

6．PPO other modified

如 polyphenylene oxide (PPO) lightfast property modified. lightfast property resin can used for electronics electrical, automotive parts, machine parts and other multiple field/area inner, can used for green engineering in used for precision device frame 架, 箱, cover/cap and other, use 二脉冲式 electrical electrical 路, electrical 传达室, light 盘显示 device and other housing/shell and 传动支架 and other. liquid 晶显示 device is table/sheet sheet/plate device used for 人计算 machine, 便携式终端 machine, machine, automotive and other.

LED use PPO材质遮 light material

发 light tube/pipe can used for electronics, automotive, and optical system inner. 我国己 in a large amount of use lightfast property modified polyphenylene oxide (PPO) production this type of light tube/pipe. also can for PPO进行PPO／PBT, PPO／PPS, PPO／PC and other. also ratio 如PPO mineral filled, fiber reinforcement and other, this application already non 常 普遍.

7．PPO chemical modified

chemical modified is PPO modified important research field/area, main/primary in PPO端基 and upper through chemical methods for PPO modified. for PPO 端羟基进行酰化 reaction, most is anti 止端羟基 by oxidation, improve/increase PPO oxidation and heat stabilized property can. currently industrial upper use methods is in 乙酰化 reaction front 进行醌偶 reaction, decrease/reduce formed low separation 子 醌 type material.

随 PPO alloy research development, can through in PPO端基引入 belt/tape has reaction active property small separation 子基团, has active 泼卤原子 or 酰卤基团 and other, rear PPO as is PPO alloy compatibilizer. PPO既 can hydrophilic electrical also can 进行自由基 reaction, 如进行 bromine reaction, acid ester reaction, ethylene reaction, amine crosslinked reaction, 羧基化 and reaction, and 氨基取代, silicon 取代, 引入烯丙基基团 and other. can in 一定程 degree upper increase PPO flexibility property, flame retardant property, resistant aging property, corrosion resistant property, improvement its solvent understanding property, improve/increase mechanical properties and other.
