Abstract
A process is disclosed for manufacturing corrosion resistant cable. In the process, a corrosion resistant, organic based, alkyl silicate-zinc coating solution is applied to wire as the wire is twisted into cable. The solution dries on the wire in air, leaving an inorganic silicate-zinc coating on the wire. The cable is then coated with a plastic. The process is particularly useful for manufacturing brake cables.
Claims15
A process for manufacturing corrosion resistant wire cable comprising:
- completely coating every wire for comprising the cable with a corrosion resistant coating solution comprising an alkyl silicate-zinc mixture in an organic base as the wire is twisted to form the cable;
- allowing said coating on said wire comprising said cable to dry by allowing said organic base to evaporate and said alkyl silicate to hydrolyze and polymerize to form a film of inorganic silicate and zinc on said wire;
- and
- coating said cable with plastic.
A process for manufacturing an automobile brake cable comprising:
- providing galvanized strands of metal wire, free of oil, grease and similar contaminants, for comprising the cable;
- completely coating said strands with an organic based alkyl silicate-zinc solution just as the strands are beginning to be twisted into cable;
- completely twisting said strands into cable;
- allowing said coating on said strands comprising the cable to dry;
- and
- coating said cable with plastic.
A corrosion resistant wire cable comprising wire completely coated with inorganic silicate and zinc, wherein said zinc comprised about 80% to about 90% of said coating, and further comprising an outside coating of plastic.
A corrosive resistant wire cable essentially comprising galvanized wire individually coated completely with inorganic silicate and zinc wherein said zinc comprises about 80% to about 90% of said coating.
An automobile brake cable comprising:
- galvanized wires, each completely coated with inorganic silicate and zinc wherein said zinc comprised about 80% to about 90% of said coating on said wires and wherein said coating is obtained by controllably and evenly applying an organic-based alkyl silicate-zinc solution to the wires as the wires are being twisted to comprise the cable and allowing the solution to dry on the wires comprising the cable;
- and
- an exterior coating of plastic.
