Abstract
Disclosed herein are methods of preparing a composite, comprising mixing a solid elastomer, a wet filler, and a resin. Single-stage or multi-stage mixing methods can be used. Also disclosed are composite comprising the filler dispersed in the elastomer at a loading of at least 20 phr, wherein the composite has a liquid content of no more than 10% by weight based on total weight of said composite.
Claims34
A method of preparing a composite, comprising:
- (a) charging a mixer with at least a solid elastomer, a wet filler comprising a filler and a liquid present in an amount of at least 15% by weight based on total weight of the wet filler, and a resin;
- (b) in one or more mixing steps, mixing the at least the solid elastomer, the wet filler, and the resin to form a mixture, and removing at least a portion of the liquid from the mixture by evaporation;
- and
- (c) discharging, from the mixer, the composite comprising the filler dispersed in the elastomer at a loading of at least 20 phr, wherein the composite has a liquid content of no more than 10% by weight based on total weight of said composite.

A method of preparing a composite, comprising:
- (a) charging a first mixer with at least a solid elastomer and a wet filler comprising a filler and a liquid present in an amount of at least 20% by weight based on total weight of wet filler;
- (b) in one or more mixing steps, mixing the at least the solid elastomer and the wet filler to form a mixture, and removing at least a portion of the liquid from the mixture by evaporation;
- (c) discharging, from the first mixer, the mixture comprising the filler dispersed in the elastomer at a loading of at least 20 phr, wherein the mixture has a liquid content that is reduced to an amount less than the liquid content at the beginning of step (b), and wherein the mixture has a material temperature ranging from 100° C. to 180° C.;
- (d) mixing the mixture from (c) in a second mixer to obtain the composite;
- and
- (e) discharging, from the second mixer, the composite having a liquid content of less than 3% by weight based on total weight of said composite,
- wherein a resin is charged to the first mixer, the second mixer, or both the first and second mixers.
