    摘要： An elastomeric composition is described which comprises at least one elastomeric component, at least one reinforcing filler, and at least one wet skid enhancing filler, for improving the wet skid resistance of the resultant composition. The wet skid enhancing filler is defined by a high Moh's hardness and large particle size. The resulting composition exhibits improved wet skid resistance compared to the same composition having no wet skid enhancing filler. Articles made from the elastomeric compositions are also described as well as methods of improving wet skid resistance and methods of making wet skid resistant materials.

    摘要： A method of making an aggregate having a carbon phase and a silicon-containing species phase is described and includes introducing a carbon black-yielding feedstock and a silicon-containing compound feedstock into different stages of a multi-stage reactor. The reactor operates at a sufficient temperature to decompose the silicon-containing compound and to form a carbon black phase from the carbon black-yielding feedstock. At least one of the feedstocks may include a diluent, such as an alcohol, water, and aqueous based solution, and mixtures thereof.

    摘要： Disclosed are elastomeric compounds including an elastomer and a silicon-treated carbon black, and optionally including a coupling agent. The elastomeric compound exhibits poorer abrasion resistance in the absence of a coupling agent, lower hysteresis at high temperature and comparable or increased hysteresis at low temperature compared to an elastomer containing an untreated carbon black. A variety of elastomers and formulations employing such elastomers are contemplated and disclosed. Elastomeric compounds incorporating an elastomer and an oxidized, silicon-treated carbon black are also disclosed. Also disclosed are methods for preparing elastomers compounded with the treated carbon black.

    摘要： A method of making an aggregate comprising at least a carbon phase and a silicon-containing species phase is disclosed. The method involves introducing a first feedstock into a first stage of a multi-stage reactor, and introducing a second feedstock into the reactor at a location downstream of the first stage. The first and second feedstock comprise a carbon black-yielding feedstock, and at least one feedstock also comprises a silicon-containing compound. The reactor is operated at a sufficient temperature to decompose the silicon-containing compound and to pyrolize the carbon black-yielding feedstock. An additional method is disclosed which involves making an aggregate comprising a carbon phase and a silicon-containing species phase using multi-stage reactor having at least three stages for introducing a feedstock, wherein at least one of the feedstocks comprises a carbon black-yielding feedstock and wherein at least one of the feedstock comprises a silicon-containing compound. Besides producing the aggregate comprising a carbon phase and a silicon-containing species phase, silica and/or carbon black may also result from the processes of the present invention. A further method is disclosed which involves making an aggregate comprising a carbon phase and a metal-containing species phase using a multi-stage reactor having at least two stages for introducing feedstocks, wherein at least one of the feedstocks comprises a carbon black-yielding feedstock and where at least one of the feedstocks comprises a metal-containing compound. The aggregates of the present invention when incorporated into elastomeric compositions preferably lead to improved wet skid resistance properties.
