Provided are a method for producing tire tread rubber, and tread rubber thereof. According to the method for producing tire tread rubber and the tread rubber thereof, the method comprises the following steps: a step (S1) of oxidizing rubber of a guayule extract to form an epoxy guayule rubber solution obtained via a reaction between an isoprene group and an epoxy group; a step (S2) of adding acid to the epoxy guayule rubber solution to solidify and dry the same; and a step (S3) of mixing the dried and solidified epoxy guayule rubber with silica or carbon black powder. According to the present invention, dispersibility of a reinforcing agent such as silica and carbon black in a rubber mixture remarkably decreases, and rotational resistance (RR) and abrasion resistance can be improved while maintaining grip performance of tire, by eliminating factors of lowering abrasion resistance due to dispersion of the reinforcing agent toward a side with higher electron density when the reinforcing agent is dispersed in various types of rubber having low compatibility.

    본 발명은 타이어 트레드고무의 제조방법 및 그 트레드고무를 제공한다. 본 발명에 따르는 타이어 트레드고무의 제조방법 및 그 트레드고무는 구아율식물 추출물의 고무를 산화시켜 아이소프렌기가 에폭시기로 반응된 에폭시구아율고무 용액을 형성하는 S1단계와, 상기 에폭시구아율고무 용액에 산을 가하여 고형화시키고 건조시키는 S2단계 및 상기 건조된 고형화 에폭시구아율고무에 실리카 또는 카본블랙 분말을 혼합하는 S3단계를 포함하는 것을 특징으로 하는데 이에 의할 때, 실리카, 카본블랙과 같은 보강제의 고무 혼합물 내에서 분산도가 현저히 떨어지고, 상용성이 떨어지는 여러가지 고무에서 보강제의 분산시 전자밀도가 높은 쪽으로 보강제가 분산되어 내마모성을 하락시키는 요인을 제거함으로써, 타이어의 Grip 성능은 유지하면서 RR, 내마모 성능이 향상될 수 있다.
