▎ 摘  要

NOVELTY - Manufacture of composite involves (a) charging a mixer with at least one solid elastomer, a wet filler comprising a filler and a liquid present in an amount of at least 15 wt.% based on the total weight of the wet filler, and a resin, (b) mixing the at least one 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 at least 20 phr filler dispersed in the elastomer. The composite has a liquid content of not more than 10 wt.% based on the total weight of said composite. USE - Manufacture of composite used for vulcanizate for article (all claimed). Uses include but are not limited to vehicle tire treads including tread and base, sidewalls, undertread, inner liners, metal binder course components, tire casings, engine mounts, bearing bushings, conveyor belts, anti-vibration devices, weather stripping, windshield wipers, automotive components, seals, gaskets, hoses, liners, cushions, housings, and wheel or track components. ADVANTAGE - The prepared composite has excellent abrasion resistance and/or increased dynamic properties. DETAILED DESCRIPTION - An INDEPENDENT CLAIM is included for manufacture of vulcanizate, which involves curing the composite in the presence of at least one curing agent.
