Patent number: 7582688Abstract: Elastomer composites are produced by novel continuous flow methods and apparatus in which 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. Novel elastomer composites are produced. Such novel elastomer composites may be cured or uncured, and combine material properties, such as choice of filler, elastomer, level of filler loading, and macro-dispersion, not previously achieved.Type: GrantFiled: December 23, 2005Date of Patent: September 1, 2009Assignee: Cabot CorporationInventors: Melinda Ann Mabry, Frederick Harry Rumpf, Ivan Zlatko Podobnik, Scott Adrian Westveer, Allan Clark Morgan, Bin Chung, Malcolm John Andrews

Patent number: 7105595Abstract: 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.

Patent number: 6040364Abstract: Elastomeric compositions are produced by novel continuous flow methods and apparatus in which fluid streams of particulate filler and elastomer latex are fed to the mixing zone of a coagulum reactor to form a mixture flowing 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. Semi-confined flow of the mixture in the coagulum zone is achieved preferably with progressively increasing cross-sectional dimension of the coagulum zone from the mixing zone to the discharge end. Highly efficient and effective elastomer coagulation can be achieved without the need for a coagulation step involving exposure to acid or salt solution or the like.Type: GrantFiled: November 17, 1997Date of Patent: March 21, 2000Assignee: Cabot CorporationInventors: Melinda Ann Mabry, Frederick Harry Rumpf, Ivan Zlatko Podobnik, Scott Adrian Westveer, Allan Clark Morgan, Bin Chung, Malcolm John Andrews
