초록
본 실험은 다양한 계면활성제를 이용해 수성 아크릴 에멀젼 접착제를 제조하고 그 특성을 조사하였다. 제조한 접착제의 특성으로 고형분, 전환율, 입도분포, 초기접착력 등의 물성을 통해 비교하였다. 접착제의 고형분을 측정한 결과는 60% 이상의 높은 값을 나타냈으며 에멀젼 중합의 전환율은 합성한 계면활성제를 2 wt% 농도로 첨가하였을 때 97%로 측정되었다. 입도분포의 분석 결과는 양이온 계면활성제를 첨가한 경우에 290∼470 nm의 작은 입자의 접착제가 제조되었고 초기접착력과 접착 발현시간 또한 증가되었다. 최대 접착력은 단일의 계면활성제(POE 23)를 사용했을 때 2.55kgf의 값을 나타냈고 다른 계면활성제를 사용한 경우보다 뛰어나다는 것을 알 수 있었다. 양이온 제미니 계면활성제를 첨가하여 제조한 접착제의 부식방지력은 48 h 동안 유지되는 것을 확인할 수 있었다.
In this study, aqueous acrylic emulsion adhesives were prepared using various surfactants and their properties were also investigated. Solids content, conversion, particle size distribution and initial adhesion properties of the prepared adhesives were compared with each other. The solid content of the adhesives was evaluated 60% and the conversion rate of the emulsion polymerization was 97% at 2 wt% concentration of synthesized surfactants. The particle size distribution analysis revealed that the size distribution of adhesive particles was 290∼470 nm when the synthesized cationic surfactant was added. The initial adhesion and adhesion time were also improved. The maximum adhesive strength was found to be 2.55 kgf when using a single surfactant (POE 23), and superior to that of using other surfactants. It was confirmed that the corrosion inhibition of the adhesive prepared by adding the cationic gemini surfactant was maintained for 48 hours.
