汽车塑料部件分为三类:内饰、外饰和功能部件。我国汽车塑料的品种按用量顺序为聚丙烯、聚氯乙烯、聚氨酯、不饱和树脂、ABS、PF、PE、PA、PC和复合材料。如果按使用量排列,德国是聚氯乙烯,聚氨酯,聚丙烯,聚乙烯,ABS;美国是聚氨酯,聚丙烯,聚乙烯,聚氯乙烯,ABS;日本是聚氯乙烯,聚丙烯,聚氨酯,ABS,聚乙烯,玻璃钢。

汽车保险杠

保险杠是汽车的主要外部部件之一。保险杠一般采用模压塑料板、改性聚丙烯材料或玻璃纤维增强塑料,通过模压、吸塑或注塑成型。


散热器格栅

散热器格栅由ABS或PC/ABS合金通过注塑成型制成。

挡泥板

挡泥板要求所用材料具有耐候性和良好的成型性。增韧聚丙烯是通过注塑成型。重型卡车大王斯太尔的挡泥板是由玻璃钢制成的。


偏转器

导流板通常重量轻、刚性高、设计新颖且呈流线型。根据不同车型的要求,一般可采用片状模塑料、玻璃钢、聚烯烃等材料,以及改性聚丙烯和ABS。中空成型导流板成本低,易于表面涂覆。

车灯

大多数前照灯使用表面涂有硬质薄膜的个人电脑。前照灯玻璃具有透明性、耐热性、耐冲击性、易成型性、耐擦伤性和耐候性。对于后指示灯组合灯,灯罩材料为PMNA,灯壳材料填充改性聚丙烯,并用热熔胶粘合。随着振动焊接技术的发展,耐热ABS被用于灯壳材料,这样灯壳和灯罩之间可以采用振动焊接,也便于材料回收。

Automotive plastic parts are divided into three categories: interior, exterior and functional parts. The varieties of automobile plastics in China are polypropylene, polyvinyl chloride, polyurethane, unsaturated resin, ABS, PF, PE, PA, PC and composite materials. In terms of usage, Germany is PVC, PU, PP, PE and ABS; USA is Pu, PP, PE, PVC, ABS; Japan is PVC, PP, PU, ABS, PE, FRP.

Car bumper

Bumper is one of the main external parts of automobile. The bumper is generally made of molded plastic plate, modified polypropylene material or glass fiber reinforced plastic, which is molded, blistered or injection molded.

Radiator grille

The radiator grille is made of ABS or PC / ABS alloy by injection molding.

Mudguard

The mudguard requires that the materials used have weather resistance and good formability. Toughened polypropylene is produced by injection molding. Heavy truck King Steyr's fender is made of glass fiber reinforced plastic.

Deflector

The deflector is usually light in weight, high in rigidity, novel in design and streamlined in shape. According to the requirements of different models, sheet molding plastics, glass fiber reinforced plastics, polyolefins and other materials can be used, as well as modified polypropylene and ABS. Hollow formed deflector has low cost and easy surface coating.

automative lighting

Most headlamps use a PC with a hard film on the surface. Headlamp glass has transparency, heat resistance, impact resistance, easy molding, scratch resistance and weather resistance. For the rear indicator lamp combination lamp, the lamp cover material is pmna, and the lamp shell material is filled with modified polypropylene and bonded with hot melt adhesive. With the development of vibration welding technology, heat-resistant ABS is used for lamp shell material, so vibration welding can be used between lamp shell and lampshade, which is convenient for material recycling.
