细数汽车用塑料的那些事
随着汽车轻量化的发展趋势,塑料在汽车中的比例越来越高。一部车下来,汽车塑料总用量可占汽车自重的5%~10%。下面就为大家“分解”一部车,看看汽车中哪些部位都用了什么塑料。
汽车内饰系统材料
仪表、门板用低VOC耐刮PP/EPDM T20,立柱用PP T20,门拉手及底座用电镀PC/PBT、PC/PBT GF,中控装饰件用电镀ABS、PC/ABS
汽车外饰系统材料
保险杠用PP/EPDM T15,侧裙用免喷涂PP/EPDM T20,翼子板用PPO/PA,轮毂盖板用PA6 MD20,格栅用耐候ASA,后视镜壳体用半芳香族尼龙,挡泥板用TPE
发动机周边材料
发动机罩盖用PA6 MD20,进气歧管用PA GF30,水室用耐醇解PA66 GF30,副水箱用耐黄变PP
HVAC系统材料
空调壳体用PP T20,冷却风扇罩用PP GF30,风扇叶片用PA66 GF30
汽车照明系统材料
车灯壳体用PP T30、耐热ABS,配光镜用PBT/PET,面罩用改性PMMA,支架用增强PPS。

沙伯基础PPO
成型工艺
1) 非结晶料、吸湿小,PPO的吸水率很低,但水分会使制品表面出现银丝、气泡等缺陷,为此,可将原料置于80~100℃的烘箱中,干燥1-2h后使用。
2)PPO的分子键刚性大,玻璃化转化温度高,不易取向,但强迫取向后很难松弛。所以制品内残余内应力较高,一般要经过后处理。
3)PPO为无定型材料,在熔融状态下的流变性接近于牛顿流体,但随温度的升高偏离牛顿流体的程度越大。
4)PPO熔体的粘度大,因此加工时应提高温度,并适当提高注射压力,以提高充模能力。
5)PPO的回料可重复使用,一般重复使用3次,其性能没有明显降低。
6)对PPO熔体宜采用螺杆式注塑机成型,喷嘴采用直通式为佳,孔径为3-6mm
7)在PPO注塑成型时,宜采取高压、高速注射,保压及冷却时间不能太长。
8)模具的主流道宜采用较大的锥度或采用拉料钩,浇道以短粗为好。
9)浇口宜采用直接式、扇形或扁平形,采用针状浇口时直径应适当加大,对于长浇道可采用热流道结构。
10)PPO的成型收缩率较小,一般为0.2%一0.7%,因而制品尺寸稳定性能优良。
11)流动性差,为类似牛顿流体,粘度对温度比较敏感,制品厚度一般在0.8毫米以上。极易分解,分解时产生腐蚀气体。宜严格控制成型温度,模具应加热,浇注系统对料流阻力应小。
12)聚苯醚的吸水率很低0.06%左右,但微量的水分会导致产品表面出现银丝等不光滑现象,最好是作干燥处理,温度不可高出150℃,否则颜色会变化。
13)聚苯醚的成型温度为280-330℃,改性聚苯醚的成型温度为260-285℃。 PPO塑胶原料注塑工艺熔料温度:270-290℃
