| description | PROBLEM TO BE SOLVED: To provide a rubber composition capable of improving on-ice brake performance, a method for producing the same, and a method for producing a tire.SOLUTION: Provided is a rubber composition comprising not-gelled water-absorbed carrageenan with the average particle diameter of 75 to 500 μm by 0.5 to 20 pts.mass to 100 pts.mass of diene rubber. Also provided is a method for producing a rubber composition comprising: a non-pro-milling step where a reinforcing filler is added to the diene rubber, and they are mixed; and a pro-milling step where a vulcanizer is added to the mixture obtained in the non-pro-milling step, and mixing is performed. In the rubber composition, moisture in the carrageenan is steam-foamed upon vulcanization to form pores in the rubber, an effect of removing a water film in a road face on ice is exhibited, and on-ice brake performance is improved.SELECTED DRAWING: None
【課題】氷上制動性能を向上させることができるゴム組成物、及びその製造方法、並びにタイヤの製造方法の提供。【解決手段】ジエン系ゴム１００質量部に対して、平均粒径が７５〜５００μｍであるゲル化していない吸水したカラギーナン粉末を０．５〜２０質量部含有する、ゴム組成物。ジエン系ゴムに補強性充填剤を添加し混合するノンプロ練り工程と、ノンプロ練り工程で得られた混合物に、加硫剤を添加し混合するプロ練り工程と、を含み、前記プロ練り工程において、前記カラギーナン粉末を、添加し、混合する、ゴム組成物の製造方法。カラギーナン中の水分が加硫時に水蒸気発泡し、ゴム中に細孔を形成し、氷上路面の水膜を除去する効果を発揮し、氷上制動性能が向上するゴム組成物。【選択図】なし |
