Abstract: The paper introduces the in-vihicle air quality control status of abroad and a company vihicle air design research and development system and control mode, It is the design concept stage, through the recognition of materials selected material and disable bill of materials, low VOC based on vehicle interior parts design vision book, after approval of the material plan to carry on the design proposal, through SD discussion with simulations verify two tools to prove the feasibility of material plan; Finally through parts VOC big data in the database set research and development of parts need checking list, the highest risk parts list. After the sampling, verifies the real vehicle in PT phase, has entered into the phase of mass production by sampling and processing mechanism of consistency control suppliers.
Key Words: VOC; SD discussion; simulation verify; disable the bill of materials
1 前言
随着汽车保有量的逐步增加,汽车逐步演变成为人们的“第二生活空间”。VOC(挥发性有机化合物)是指在常压下,沸点为50~260℃的各种有机化合物。车内VOC浓度是表征车内空气质量的重要指标,直接关系到司乘人员的健康。2012年《乘用车内空气质量评价指南》的标准发布,标准限制车内空气中苯、甲苯、二甲苯、乙苯、苯乙烯、甲醛、乙醛、丙烯醛八项物质的最高浓度,促使汽车生产企业更加重视车内空气质量问题。
车内VOC的来源主要为汽车内饰零部件,这些零部件主要由塑料、胶黏剂、皮革、聚氨酯材料、橡胶、纤维材料的组合,其中VOC主要来源于以下五方面:
1.橡塑材料合成用助剂:由单体制备合成树脂、合成橡胶等高分子材料的过程所需要的助剂,如阻聚剂、引发剂、乳化剂和分散剂等。……
