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: The present invention relates to a brass-plated high carbon steel wire having applied thereto an aqueous zinc phosphate solution having a pH of from about 2 to about 3 and containing (1) a total of from about 28 to 32 grams per liter of phosphoric acid, (2) from about 8 to 11 grams per liter of free phosphoric acid, (3) from about 8 to 12 grams per liter of Zn.sup.+2 which may be derived from the group consisting of zinc oxide, zinc phosphate or mixtures thereof, and (4) wherein the mole ratio of total phosphoric acid to free phosphoric acid ranges from 2.5:1 to 04.0:1. In accordance with the present invention, the zinc phosphate coating on the brass-plated steel cord inhibits corrosion and adhesion of the wire to rubber after vulcanization is improved.

Abstract: The present invention relates to a process for treating a brass-plated steel wire comprising applying to the wire an aqueous zinc phosphate solution having a pH of from about 2 to about 3 and containing (1) a total of from about 28 to 32 grams per liter of phosphoric acid, (2) from about 8 to 11 grams per liter of free phosphoric acid, (3) from about 8 to 11 grams per liter of Zn.sup.+2 which may be derived from the group consisting of zinc oxide, zinc phosphate or mixtures thereof, and (4) wherein the mole ratio of total phosphoric acid to free phosphoric acid ranges from 2.5:1 to 4.0:1. In accordance with the present invention, the zinc phosphate coating on the brass-plated steel cord inhibits corrosion and adhesion of the wire to rubber after vulcanization is improved.

Abstract: Copper plating cells which utilize soluble copper anodes which replenish the electrolyte with copper ions are normally used for applying copper layers to steel filaments. The amount of copper in such soluble anodes is diminished throughout the plating procedure and ultimately such soluble copper anodes need to be replaced. It has been discovered that insoluble anodes can be utilized in such plating cells.

Abstract: This invention reveals a steel wire element useful in the reinforcement of rubber articles in which the steel wire is provided with an adhesive coating comprising a ternary brass alloy containing about 55 percent to about 75 percent by weight copper, about 15 to about 45 percent by weight zinc, and about 0.1 to about 10 percent by weight iron. Preferably this ternary brass alloy will contain about 1 to 5 percent by weight iron. The ternary alloy may be formed by sequentially electroplating layers of copper, iron and zinc followed by heating to promote the diffusion of the copper, iron and zinc layers. The steel wire elements of this invention are useful in the reinforcement of vehicle tires, power transmission belts, conveyor belts, hoses, and the like.

Abstract: An aqueous acidic plating bath for the electrodeposition of a bright zinc deposit on a substrate is disclosed and comprises zinc ions, and an amount sufficient to provide a level and bright zinc electrodeposit, of a polymeric sulfur-containing compound having the general formulaRS(R'O--.sub.n H, or (I)(S[(R').sub.n H].sub.2 (II)wherein R is an alkyl group containing up to about 24 carbon atoms, each R' is independently an alkylene group containing 2 or 3 carbon atoms and each n is independently an integer of from 1 to about 100.Additionally, the plating baths of the invention may contain at least one aromatic carbonyl-containing compound and particularly aromatic aldehydes and aromatic carboxylic acids. Aromatic sulfonic acids and ethylene oxide condensates of such sulfonic acids also are useful in the plating baths of the invention. Other ethylene oxide condensates can be included in the baths including those derived from carboxylic acids, amides, amines, alcohols, phenols and naphthols.

Abstract: Nitrogen and sulfur compositions are described which are useful in aqueous acidic plating baths and processes for electrodepositing bright and level copper coatings. The compositions are prepared by reacting a mixture of(a) a disulfide having the formula[RR'NCS.sub.2 ].sub.2 (Formula I)wherein R and R' are each independently hydrogen, alkyl or aryl groups, and(b) a halo hydroxy sulfonic acid having the formulaX(CH.sub.2).sub.n CHOH--CH.sub.2 SO.sub.3 M (Formula II)wherein X is a halogen, n is one or two and M is hydrogen or an alkali metal, in(c) an aqueous alkaline medium.Particularly bright and level deposits are obtained when the reaction mixture used to form the composition also contains an aliphatic aldehyde containing up to three carbon atoms. The presence of the above-described brightening and leveling agents in acid copper plating baths produces a lustrous, smooth and level deposit of copper over a wide range of current densities, particularly when wetting agents are included in the plating baths.
