  • Patent number: 4236564
    Abstract: A rubber-free heat reactable phenol-formaldehyde resin adhesive is used to bond bright steel tire cords to the tire rubber.
    Type: Grant
    Filed: May 10, 1979
    Date of Patent: December 2, 1980
    Assignee: The General Tire & Rubber Company
    Inventors: Edward F. Kalafus, Satish C. Sharma
  • Patent number: 4134869
    Abstract: An alkaline aqueous emulsion of a rubbery vinyl pyridine copolymer is stabilized by the presence of a minor amount by weight of a resorcinol-formaldehyde novolak wherein said emulsion is free of soaps added after the polymerization of the copolymer. High H-adhesions are obtained with cord dips made using the stabilized emulsion.

  • Patent number: 4070318
    Abstract: 2,6-Bis(2,4-dihydroxy phenylmethyl)-4-chlorophenol is made by a low catalyst level process which eliminates the need to isolate the 2,6-bis hydroxymethyl-4-chlorophenol intermediate or the 2,6-bis(2,4-dihydroxy phenylmethyl)-4-chlorophenol from the reaction mixture. The 2,6-bis(2,4-dihydroxy phenylmethyl)-4-chlorophenol blended with a vinyl pyridine latex is used as a polyester cord dip. The dipped cord is used as reinforcement in rubber tires.
    Type: Grant

  • Patent number: 4051281
    Abstract: An aqueous alkaline dispersion of a rubbery vinyl pyridine copolymer, trimethylol phenol, and a resorcinol compound, in certain amounts, is useful in forming an adhesive for bonding glass fiber reinforcing elements or cords to rubber compounds or stocks. After dipping the glass fiber cord in the one-step adhesive dip, the coated cord is heated to dry it and heat cure or heat set the adhesive on the cord. Thereafter, the adhesive containing glass fiber cord is combined or laminated (calendered) with a curable rubber compound and the resulting assembly is cured to form a composite in which the glass fiber cord is bonded to the rubber by means of said adhesive.

  • Patent number: 3991027
    Abstract: An aqueous alkaline dispersion of a rubbery vinyl pyridine copolymer, trimethylol phenol, and a resorcinol compound, in certain amounts is useful in forming an adhesive for bonding polyamide or nylon cords to rubber compounds or stocks. After dipping the cord in the adhesive dip, the coated cord is heated to dry it and heat cure or heat set the adhesive on the cord. Thereafter, the adhesive containing cord is combined or laminated (calendered) with a curable rubber compound and the resulting assembly is cured. High H-adhesions are obtained with this one-step or single treatment coating dip. It is particularly useful for bonding crystalline polyamides having a large number of aromatic groups in the polymeric structure, e.g., "Fiber B.

  • Patent number: 3947394
    Abstract: Rubber compounds are readily bonded to polyester reinforcing elements, particularly tire cords of polyester fibers, using a one-step dip process in which the dip consists essentially of an alkaline aqueous emulsion of a minor amount by weight of a mixture of a major amount by weight of a rubbery vinyl pyridine copolymer and a minor amount by weight of a heat reactable 2,6-bis(2,4-dihydroxy phenylmethyl)-4-chlorophenol composition, wherein said emulsion is essentially free of alkali metal materials and wherein the emulsifier used in the emulsion is an ammonium salt or soap. High aged H-adhesions are obtained with this process.
