초록

타이어 트레드 컴파운드와 천연 및 합성 고무 접착제 종류에 따른 가황 전/후의 점착력과 접착력 차이를 비교하였다. 가황 전 점착력은 모든 트레드에서 천연고무 시멘트가 가장 강하고, 시간의 경과에 따른 점착력 감소도 천연고무 시멘트가 합성고무 시멘트보다 낮았다. 가황 전 점착력은 시멘트에 사용된 고무의 유리전이온도에 영향을 받았으며, 천연고무가 합성고무에 비해 시간의 경과에 따른 점착력 감소도 적었다. 가황 후 접착력은 천연고무 시멘트가 천연고무가 주성분인 트레드에 강하게 접착하지만 합성고무가 주성분인 트레드에는 약하게 접착했다. 반면 유화중합 SBR, 용액중합 SBR 시멘트는 모든 트레드 컴파운드에 강하게 접착하였고, 시멘트 고무의 가황 속도가 느릴수록 강한 접착력을 보였다.

This study compared the tackiness and adhesion of different tire tread compounds and rubber cements before and after vulcanization. The tackiness of natural rubber (NR) cement was the highest for all tread compounds before vulcanization, and the decrease in tackiness of NR cements over time was smaller than that of synthetic rubber cements. The tackiness before vulcanization was affected by the glass transition temperature of the rubber used in the cement and the decrease in tackiness over time of NR was smaller compared to that of using the synthetic rubber. The adhesion of NR-based cements after vulcanization was high for NR tread compounds but low for synthetic rubber tread compounds. On the contrary, the adhesion of emulsion (SBR) and solution SBR cements was high on all tread compounds which was shown to be higher when the rate of vulcanization of cement rubber was lower.
