座椅发泡胺类物质残留量对整车气味的影响

Influence of Seat Foaming Amines Residual on Vehicle Odor

由于座椅发泡使用非反应型胺类催化剂容易产生氨臭味,直接影响整车气味。文中从实际座椅发泡气味表现与发泡实际生产效率和成本角度出发,将发泡所表现出来的氨味接受程度与胺类催化剂的气味阈值相结合,来获得合理的胺类物质限值,可实现通过对座椅发泡胺类催化剂残留量的控制,为发泡产品气味一致性提供可靠客观依据。

As non reactive amine catalysts are used for seat foaming,ammonia odor is easy to be generated,which directly affects the odor of the whole vehicle.From the actual seat foaming odor performance and the actual production efficiency and cost of foaming,the ammonia odor acceptance degree of foaming was combined with the odor threshold of amine catalyst to calculate and give a reasonable amine material limit.It can realize the control of the residual amount of seat foaming amine catalyst and provide reliable and objective basis for the odor consistency of foaming products basis.
