Abstract

Adhesive strength was evaluated for the polyester fabric treated with various concentration of polymeric isocyanate to introduce functional group on the surface. Also experiments were performed to find out the type of latex, F/R mole ratio, and FR resin/latex weight ratio for the RFL solution to optimize adhesion between HNBR compound and the treated polyester fabric. Optimum adhesion strength was obtained when 7 wt% of the concentration of polymeric isocyanate, NBR latex because of the compatibility of HNBR compound, 1/1 of F/R mole ratio, and 20 wt% of FR resin/latex were applied. Optimum cure temperature for the RFL solution was $200^{\circ}C$ according to the results of peel test and the reason was determined by analyzing the ATR FTIR spectra of the RF resin according to the curing temperature.

본 연구에서는 polyester 섬유표면에 활성기를 부여하기 위한 전처리제로 isocyanate를 이용하여 농도에 따른 접착력을 평가하였다. 이 후 HNBR compound와 polyester fabric의 접착 시 접착력이 우수한 RFL 용액용 latex 선정 및 F/R mole ratio, F/R resin/latex 무게 비에 따른 실험을 진행하였다. 그 결과 전처리제의 농도가 7 wt%인 경우 가장 높은 접착력을 나타내었으며, RFL 용액용 latex로는 HNBR 컴파운드와 상용성이 높은 NBR latex가 우수한 결과를 나타내었고 F/R mole ratio, FR resin/latex 무게비가 각각 1/1, 20%일 때 가장 높은 접착력을 나타내었다. 또한, peel test와 FTIR 분석을 이용해 RF resin의 열처리 온도에 따른 접착강도와 spectra의 peak 변화를 평가해 본 결과 최적의 열처리 온도는 $200^{\circ}C$이었다.
