본 발명의 극성 기능성(functionality)을 갖는 하나 이상의 고무 및 하나 이상의 극성 필러를 포함하는 고무 화합물은: (ⅰ) 극성 휘발성 액체를 극성 필러에 첨가하는 단계; (ⅱ) 극성 기능성을 갖는 하나 이상의 고무를 극성 휘발성 액체 및 극성 필러와 혼합하여, 하나 이상의 고무 안에 극성 필러의 분산액을 생성하는 단계; 및 (ⅲ) 분산액으로부터 극성 휘발성 액체를 제거하는 단계를 포함하는 방법에 의해 제조된다. 본 발명은 침전 실리카와 같은 극성 보강 필러를 함유하며, 에폭시화 천연고무와 같은 극성 기능성을 갖는 탄성체에 근거하여, 고무 화합물의 혼합의 일관성 및 균일성을 개선하며, 상기 화합물은 가황시 개선된 기계적 특성을 가진다. 상기 방법은 차량 타이어의 제조에 특히 유용하다.

    Rubber compounds comprising one or more rubber with polar functionality and one or more polar filler are prepared by a method comprising the steps: (i) adding a polar volatile liquid to the polar filler; (ii) mixing the one or more rubber with polar functionality with the polar volatile liquid and polar filler to produce a dispersion of the polar filler in the one or more rubber; and (iii) removing the polar volatile liquid from the dispersion. The invention Improves the consistency and uniformity of mixing of rubber compounds based on elastomers having polar functionality, such as epoxidized natural rubber, containing polar reinforcing fillers, such as precipitated silica, The compounds, when vulcanized, have improved mechanical properties. The method is particularly useful in the manufacture of vehicle tires.
