摘要： Elastomer composite blends are produced by novel wet/dry mixing methods and apparatus. In the wet mixing step or stage, fluid streams of particulate filler and elastomer latex are fed to the mixing zone of a coagulum reactor to form a mixture in semi-confined flow continuously from the mixing zone through a coagulum zone to a discharge end of the reactor. The particulate filler fluid is fed under high pressure to the mixing zone, such as to form a jet stream to entrain elastomer latex fluid sufficiently energetically to substantially completely coagulate the elastomer with the particulate filler prior to the discharge end. Highly efficient and effective elastomer coagulation is achieved without the need for a coagulation step involving exposure to acid or salt solution or the like. Elastomer composites are produced. Such elastomer composites may be cured or uncured, and combine material properties, such as choice of filler, elastomer, level of filler loading, and macro-dispersion, nor previously achieved. The coagulum produced by such wet mixing step, with or without intermediate processing steps, is then mixed with additional elastomer in a dry mixing step or stage to form elastomer composite blends. The additional elastomer to the coagulum may be the same as or different from the elastomer(s) used in the wet mixing step.

摘要： PROBLEM TO BE SOLVED: To provide a new elastomer composite. SOLUTION: The firmly bonded elastomer composite is produced without using a coagulant of acid or salt by supplying a particulate filler of high flow velocity and an elastomer latex of low flow velocity to a mixing zone of a coagulum reactor, and mixing and coagulating them in a high-shearing flow and turbulent flow state caused in the mixing zone. Such an elastomer composite has the effect that macro-dispersion of the particulate filler is remarkably excellent. COPYRIGHT: (C)2009,JPO&INPIT
