Abstract
부타디엔 고무 소재의 접착력을 향상시키기 위하여 대기압 표면개질방식을 적용시켰다. 평판형 플라즈마반응기의 최적의 반응조건을 구하기 위하여 반응기체(질소, 아르곤, 산소, 공기), 기체유량(30~100 mL/min), 플라즈마 처리시간(0~30초) 및 선처리제의 개질방법(GMA, 2-HEMA)을 변화시켜 실험하였다. 처리 전후의 소재의 표면변화는 SEM과 ATR-FTIR로 측정하였다. 기체의 유량과 처리시간이 증가함에 따라 접촉각이 감소하였고, 반응 기체는 공기로 유량 60 mL/min, 처리시간 5초 및 2-HEMA 첨가 선처리제를 사용하였을 때 최대의 접착박리강도를 나타내었다. 결과적으로 대기압식 평판형 플라즈마 처리방식으로 고무소재 표면의 젖음성과 접착박리강도가 개선 되었음을 확인하였다.
An atmospheric surface modification using plasma treatment method was applied to butadiene rubber to improve its adhesion strength by plate type reactor. In order to investigate the optimum reaction condition of plasma treatment, type of reaction gas(nitrogen, argon, oxygen, air), gas flow rate(30~100 mL/min), treated time(0~30 s) and primer modification method(GMA, 2-HEMA) were examined in a plate type plasma reactor. The results of the surface modification with respect to the treatment procedure was characterized by using SEM and ATR-FTIR. As the gas flow rate and treated time increases the contact angle decreases. The greatest adhesion strength was achieved at optimum condition such as flow rate of 60 mL/min, treated time 5 s and modification primer containing 2-HEMA for air. Due to the atmospheric surface modification using plate plasma method consequently reduced the wettability of butadiene rubber and resulted in the improvement of the adhesion.
