摘要： The invention relates to a sulfur-crosslinkable rubberization mixture for metallic or textile strength members containing at least one novolac resin comprising alkyl urethane units and produced by reaction of a phenolic compound, an aldehyde and a carbamate resin, wherein the carbamate resin is produced by reaction of alkyl urethane with an aldehyde, and at least one etherified melamine resin. The invention further relates to a pneumatic vehicle tire which comprises at least one such sulfur-crosslinked rubberization mixture.
For improved durability of the rubberized strength members, the rubberization mixture contains
less than 2.5 phr (parts by weight, based on 100 parts by weight of the total rubbers in the mixture) of at least one novolac resin comprising alkyl urethane units and produced by reaction of a phenolic compound, an aldehyde and a carbamate resin, wherein the carbamate resin is produced by reaction of alkyl urethane with an aldehyde, and
less than 2.5 phr of at least one etherified melamine resin.-

摘要： Modified thermoplastic hydrocarbon thermoplastic resins are provided, as well as methods of their manufacture and uses thereof in rubber compositions. The modified thermoplastic resins are modified by decreasing the relative quantity of the dimer, trimer, tetramer, and pentamer oligomers as compared to the corresponding unmodified thermoplastic resin polymers, resulting in a product that exhibits a greater shift in the glass transition temperature of the elastomer(s) used in tire formulations. This translates to better viscoelastic predictors of tire tread performance, such as wet grip and rolling resistance. The modified thermoplastic resins impart remarkable properties on various rubber compositions, such as tires, belts, hoses, brakes, and the like. Automobile tires incorporating the modified thermoplastic resins are shown to possess excellent results in balancing the properties of rolling resistance, tire wear, snow performance, and wet braking performance.

摘要： A sulfur-crosslinkable rubberizing mixture for strengthening elements in motor vehicle pneumatic tires comprises 70 to 100 phr (parts by weight, based on 100 parts by weight of total rubbers in the mixture) of natural rubber, up to 30 phr of at least one polybutadiene, up to 15 phr of at least one carbon black, 20 to 100 phr of at least one high-dispersibility silica, at least one silane coupling agent and a bonding system. The invention further relates to motor vehicle pneumatic tires comprising the sulfur-crosslinked rubberizing mixture. For improved resistance to cracking and growth of cracks with good adhesion and good mechanical and dynamic properties, the high-dispersibility silica has a CTAB number to ASTM D 3765 of more than 130 m2/g.

摘要： A sulfur-crosslinkable rubberizing mixture for strengthening elements in motor vehicle pneumatic tires comprises 70 to 100 phr (parts by weight, based on 100 parts by weight of total rubbers in the mixture) of natural rubber, up to 30 phr of at least one polybutadiene, 40 to 70 phr of at least one carbon black and a bonding system. Further, motor vehicle pneumatic tires are disclosed that comprise the sulfur-crosslinked rubberizing mixture. The key conflict between tear propagation resistance, stiffness and heat build-up is solved by virtue of the carbon black being a nanostructured carbon black with a rough surface.
