Abstract

In order to improve adhesion properties and water resistance of waterborne polyurethane adhesives, allyl 3-(trimethoxy silyl)propyl ether (ATSE) was prepared. Waterborne polyurethane acrylate silanes (WPAS) was synthesized using ATSE. Their chemical structures were confirmed by FTIR and 1H NMR, and their thermal properties were characterized by DSC and TGA. Analyses of DSC and TGA confirmed that heat capacity of soft segment decreased and thermal stability improved with increasing ATSE. Also, adhesion properties and water resistance were evaluated by UTM. In the adhesion properties and water resistance test, the maximum values were obtained by WPAS containing 2.91 wt% ATSE.


수성접착제의 접착특성을 향상시키기 위하여 allyl 3-(trimethoxy silyl)propyl ether(ATSE)를 합성하고 이를 waterborne polyurethane acrylate에 적용하여 접착제를 제조하였다. FTIR과 1H NMR을 사용하여 ATSE의 합성을 확인하였다. 또한 FTIR을 통해 수성 폴리우레탄 아크릴레이트 실란(WPAS)의 합성을 확인하였고 DSC와 TGA를 사용하여 WPAS의 열적특성을 확인하였다. DSC와 TGA 분석을 통하여 ATSE의 함량이 증가할수록 soft segment의 열용량이 감소하고, 열안정성이 향상되는 것을 확인하였다. 또한 ATSE 함량에 따른 접착특성을 평가한 결과, ATSE의 함량이 2.91 wt%일 때에 상태접착력 및 내수성이 가장 우수하였다.
