活性炭填充乘用车座椅泡沫对气味VOC影响的研究

乘用车座椅是车内表面积最大的零部件,是车内空气异味与VOC的主要来源之一。将改性后的活性炭加入到聚氨酯泡沫反应体系中,得到1种能持续吸收聚氨酯泡沫中残留的小分子异味物质的材料。研究了不同粒径的改性活性炭在异氰酸酯溶液中的分散性,找到了活性炭填充的最佳粒径范围。在保证聚氨酯泡沫力学强度的基础上,填充的活性炭起到良好地吸收车内异味及VOC的作用。

Study on Effect of Active Carbon Filled Passenger Car Seat Foam on Odor and VOC

Passenger car seats are the largest components of surface area and the main source of unpleasant odor and VOC in the car.A modified active carbon is filled to polyurethane foam reaction system,and a kind of material that can absorb unpleasant odor molecules continuously in the polyurethane foam is obtained.The dispersion of modified active carbon with different particle sizes is studied in isocyanate solution,and the best particle sizes range of modified active carbon is found.While maintaining the mechanical properties of polyurethane foam.It is cbserved that the absorbency of interior odor and VOC is improved by the filled active carbon.
