摘　　要：汽车的各项配置中对人们舒适度影响最大的是汽车座椅以及软包中所使用的PVC汽车复合海绵。PVC汽车复合海绵大多为白色,但经过不断使用,PVC汽车复合海绵会逐步变黄。PVC汽车复合海绵黄变的主要原因是PVC汽车复合海绵在长期的使用过程中,其在生产制造中所加入的抗氧化剂以及稳定剂等会产生氧化还原反应而黄变。这一现象的出现不仅会直接影响到车辆的美观程度,同时也会导致车辆的清洁度出现严重下降,从而影响到用户的正常使用。为避免这一现象的出现,需要分析PVC汽车复合海绵的变黄原因,针对性的制定出相应的缓解措施。文章就PVC汽车符合海绵变黄原因进行论述并提出相应的处理对策。Among the various conf igurations of the car,the PVC composite sponge used in the car seat and soft bag has the greatest impact on people’s comfort.Most of the PVC automobile composite sponges are white,but the PVC automobile composite sponges will gradually turn yellow after continuous use.The main reason for the yellowing of PVC automobile composite sponge is that in the long-term use process,the antioxidants and stabilizers added in the production of PVC automobile composite sponge will produce oxidation-reduction reaction and yellowing.This phenomenon will not only directly affect the beauty of the vehicle,but also lead to a serious decline in the cleanliness of the vehicle,thus affecting the normal use of users.In order to avoid this phenomenon,it is necessary to analyze the yellowing reasons of PVC automobile composite sponge and formulate corresponding mitigation measures.This paper discusses the reasons for the yellowing of PVC automobile sponge and puts forward the corresponding countermeasures.
