TL;DR: In this article, a wet/dry mixing method and apparatus for elastomer composite blends is presented, where the mixture of elastomers and filler is fed to the mixing zone of a coagulum reactor to form a mixture in semi-confined flow.
Abstract: 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, not 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.

TL;DR: In this paper, a method for producing an elastomer composite blend, which comprises: supplying a continuous flow of a first fluid containing elastomers to the mixing zone of a coagulum reactor, and supplying under pressure a second fluid containing a particulate filler, to form a mixture with the elastsomer latex, was provided.
Abstract: PROBLEM TO BE SOLVED: To provide an elastomer blend containing carbon black in a mixture of natural rubber with a synthetic elastomer and improved in macro dispersion. SOLUTION: There is provided a method for producing an elastomer composite blend, which comprises: supplying a continuous flow of a first fluid containing elastomer latex to the mixing zone of a coagulum reactor, and supplying under pressure a continuous flow of a second fluid containing a particulate filler to the mixing zone of the coagulum reactor to form a mixture with the elastomer latex, wherein the particle filler is effective for coagulating the elastomer latex, and the mixing of the first fluid with the second fluid in the mixing zone generates sufficient energy to practically perfectly coagulate the elastomer latex in the coagulum reactor with the particulate filler; discharging the practically continuous flow of the elastomer composite materials from the coagulum reactor; and dry-mixing the elastomer composite materials with an additional elastomer to form the elastomer composite blends.

Abstract: The present invention relates to an aqueous adhesive composition, comprising at least A) a phenol-aldehyde resin and B) an unsaturated elastomer latex, characterised in that the base of the phenol-aldehyde consists of at least: an aromatic polyaldehyde bearing at least two aldehyde functions that comprise at least one aromatic ring; a polyphenol comprising one or more aromatic ring(s), it being understood that: in the case of a single aromatic ring, said ring bears two or three hydroxyl functions in meta position relative to each other, the rest of the ring being unsubstituted; in the case of multiple aromatic rings, at least two of said rings each bear two or three hydroxyl functions in meta position relative to each other, it being understood that the two ortho positions of at least one of these hydroxyl functions are unsubstituted. Such an adhesive composition is usable particularly to enable adhesion between a textile material and a crosslinkable rubber composition, and is an advantageous alternative to using a formaldehyde-based RFL adhesive.

TL;DR: In this paper, an elastomer mixture resulting from the modification of a diene elastic mixture by a coupling agent that inserts an alkoxysilane bearing a tertiary or secondary amine function into the elastic chain is described.
Abstract: The invention relates to an elastomer mixture resulting from the modification of a diene elastomer by a coupling agent that inserts an alkoxysilane bearing a tertiary or secondary amine function into the elastomer chain. The mixture mainly comprises a diene elastomer coupled by the alkoxysilane group bearing a tertiary or secondary amine function bonded to the diene elastomer via the silicon atom. The invention also relates to a reinforced rubber composition which can be used in particular to make tyres and which comprises a reinforcing filler as well as an elastomer matrix including at least said elastomer mixture, and to a method for preparing same. The composition has improved hysteretic and mechanical properties in the vulcanised state and improved processability in the green state.
