HS-SPME-GC/MS 법을 이용한 PVC벽지 원자재의 TVOC 기여도 평가

Abstract

A wallpaper having many surfaces in indoor is composed of various raw materials. In this study,TVOC contribution from raw materials of PVC walpaper was evaluated by using headspace-solid phasePVC resin. 9 mL of each sample was put into 22 mL glass vial and they were equilibrated for 1 hour at100oC. Headspace in vial was absorbed to 75 m Carboxen-PDMS fiber and analyzed by GC/MS. Aromaticcompounds like a toluene, ethylbenzene and xylene, ketones compounds like a acetone, methoxyacetone and2-butanone and alkane compounds like a nonane decane and undecane were identified from raw materials. And. Corresponding authorPhone : +82-(0)3-250-8576 Fax : +82-(0)33-251-3991E-mail : mgkim@kangwon.ac.krHS-SPME-GC/MS .. ... PVC.. ....

TVOC emision of diluent, resinstabilizer, plasticizer, PVC resin, blowing agent and filler were 54.20g/g, 32.88g/g, 0.50g/g, 0.88g/g,0.22g/g and 0.11g/g, respectively. Contribution of TVOC emission of diluent, resin stabilizer and PVC resinthat were concerned about add ratio were 0.708, 0.129, 0.115, respectively. In conclusion, it's necessary to reduceTVOC emision through improvement of diluent, resin stabilizer and PVC resin. Also, HS-SPME-GC/MSmethod which was developed in this study will be used for raw materials analysis effectively.
