This invention relates to a composite of a melamine derivative, particularly a liquid melamine derivative, and carbon black. A representative melamine derivative is, for example, comprised of an alkoxymethylmelamine such as hexamethoxymethylmelamine. The invention further relates to a rubber composition containing such composite of a melamine derivative and carbon black and to a rubber composition containing such composite as a methylene donor in combination with a methylene acceptor and the reaction product thereof in situ within said rubber composition. Such rubber composition may be a component of an article of manufacture, which may contain or be exclusive of, wire reinforcement, such as for example a component of a tire, vehicular track or industrial belt or hose.

A method of making a tire mold segment with a porous metal tread surface for a tire mold wherein an annular segmental tire model of refractory material is formed with tire model segments which are used to shape and form each tire mold segment from powdered metal by applying heat and pressure to sinter the powdered metal as it is shaped by the tire model segment. Blades may be mounted in the tire model segments for transfer to the tire mold segments for molding slits a tire tread.

Method of making a porous tire tread mold

Making a tire mold having a plurality of complete tire mold segments ( ) of epoxy resin mold material formed in the chambers ( ) of segmental shoes ( ) and having reinforced stand alone ribs ( ) formed in recesses in the tread models mounted in the shoes. The shoes ( ) and models ( ) are reusable and have standard shoe split diameters and chord lengths to reduce the time necessary to make the molds. The models ( ) are of resilient material and are also reusable.

Tire mold reinforcement

A method for securing splices in uncured rubber articles prior to vulcanization and secured splices resulting therefrom. The method includes covering a splice and two ends of uncured rubber with syndiotactic 1,2-polybutadiene, adhering the syndiotactic 1,2-polybutadiene to the uncured rubber adjacent to the splice, and curing the rubber. The rubber compound to which the syndiotactic 1,2-polybutadiene is adhered does not have to contain syndiotactic 1,2-polybutadiene. In addition, because the syndiotactic 1,2-polybutadiene is preferably melted into the rubber compound, there are no uniformity problems caused by the additional layer over the splice.
