Abstract: Steel cables are utilized for reinforcing a wide variety of rubber articles. For instance, pneumatic tires are normally reinforced with steel tire cords. It is important for such reinforcing cables to exhibit good fatigue and corrosion resistance. It has been unexpectedly found that the fatigue and corrosion resistance of such cables can be improved by incorporating syndiotactic-1,2-polybutadiene into the interstices between the steel filaments in such cables. This invention more specifically relates to a cable for reinforcing rubber articles having improved fatigue and corrosion resistance which is comprised of a plurality of steel filaments and syndiotactic-1,2-polybutadiene, wherein the syndiotactic-1,2-polybutadiene is dispersed within interstices between said steel filaments.

Abstract: This invention reveals steel alloys which are particularly suitable for use in manufacturing reinforcing wires for rubber products, such as tires. The steel filaments made by this process have an outstanding combination of strength and ductility. Additionally, the steel alloys of this invention can be patented in a low cost process due to their having a very fast rate of isothermal transformation. This allows the steel in the steel wire being patented to transform from a face centered cubic microstructure to an essentially body centered cubic microstructure within a very short period. This invention more specifically discloses a steel alloy composition which is particularly suitable for use in manufacturing reinforcing wire for rubber products which consists essentially of (a) about 92.8 to about 99.18 weight percent iron, (b) about 0.4 to about 1.5 weight percent carbon, (c) about 0.05 to about 1 weight percent silicon, (d) about 0.05 to about 1.2 weight percent manganese, (e) about 0.01 to about 1.

Abstract: A method for making a knotless bead bundle, a bead bundle made according to the method, and a tire made using the knotless bead bundle are provided. In the method a bead ring is made using a plurality of annular turns of wire as is conventional in the art, and the annular turns of wire are wrapped with cord, tape, or other conventional wrapping material which is held on the bead ring without using knots. The wrap is held on the bead ring by using a tie down area that is made by forming a loop in the wrapping material, holding the loop in place by a number of close turns of wrap on the bead ring while leaving a first end of the wrapping material free, wrapping the bead ring 360.degree. around the ring, passing a second end of the wrapping material through the loop, closing the loop by pulling the first end of the wrapping material whereby closing the loop pulls the second end of the wrapping material under the close turns of wrapping material.

Abstract: The vulcanized, aged, adhesion of rubber to brass-coated steel cord is improved by the use of benzotriazole (BTA) and cyclohexylamineborate (CHAB). The BTA and CHAB are used alone or in combination. They are added directly to the surface of the cord or to the rubber immediately adjacent to the cord. BTA treatment will reduce surface contamination of the cord. CHAB will aid in improving aged adhesion.

Abstract: The vulcanized aged adhesion of rubber to clean brass coated steel cord is improved by the use of benzotriazole (BTA) and/or a precipitation compound such as cyclohexylamine borate and/or an oxidation compound such as zinc chromate. These agents are added directly to the surface of the cord or to the rubber immediately adjacent to the cord. BTA treatment reduces surface degradation of the cord and the precipitation compound and oxidation compound aid in improving aged adhesion. Preferably the cord is cleaned in an acid dip, which can be used to deposit desired anions on the cord surface, prior to treatment.
