Abstract

An atmospheric plasma pre-treatment method was applied to PU foam, Leather (Action), Rubber to improve its adhesion using solvent and water soluble type pressure sensitive adhesion in atmospheric plate type reactor. In order to investigate the optimum reaction condition of plasma treatment, type of reaction gas (nitrogen), rate of gas flow (30~100 mL/min), and reaction time (0~30 s) were examined in a plate plasma reactor. The result of the surface modification with respect to the treatment procedure was characterized by using SEM. Due to a de-crease of the contact angle of various materials, the greatest adhesion strength was achieved at optimum condition such as flow rate of 100 mL/min, reaction time of 10 second for an atmospheric plasma treatment of the PU foam, EVA foam, Leather (Action) and Rubber also resulted in the improvement of the adhesion.

용제 및 수용성 접착제를 도포한 몇가지 고분자 소재에 평판형 플라즈마 반응기로 플라즈마 전처리 방식을 이용하여 소재표면의 접착력을 향상 시켰다. 분위기 기류를 질소로 하고 유량을 30~100 mL/min, 반응시간은 0~30 s로 하여 밀도를 변화시킨 PU 소재를 주 물질로 하여 EVA foam, Leather (Action), Rubber 소재에 대하여 각 조건별로 플라즈마 처리시켜 처리 전후의 각 소재별 접촉각과 접착박리강도 측정을 통한 각소재의 접착력 변화와, SEM분석을 이용한 처리 전후의 표면 변화를 측정하여 플라즈마 처리의 영향과 효과를 산출하였다. 대기압 평판형 플라즈마 반응기를 이용하여 최적 조건인 기체유량 100 ml/min, 전처리시간 10 s에서 PU foam, EVA form, Leather (Action) 및 Rubber 소재의 접착력 향상을 확인하였다.
