Definitions

  • Known transmission belt coatings typically contain fluoropolymers, which may potentially include minor amounts of per/polyfluoroalkyl substances (PFAS).
  • PFAS per/polyfluoroalkyl substances
  • the fluoropolymer regulatory landscape has become increasingly concerned about PFAS as a constituent of substances and/or mixtures, so it would be desirable to provide a coating composition for flexible substrates, for example, power transmission belts, which are substantially free of PFAS.
  • a coating composition for flexible substrates including a binder resin, a lubricating component in the form of lubricating filler particles of a hydrocarbon wax and/or polyethylene, and a solvent.
  • the coating composition is wear resistant and is substantially free of fluoropolymers.
  • the present disclosure provides a coating composition for flexible substrates, comprising: a binder resin, a solvent, and a lubricating component comprising at least one of: lubricating filler particles comprising a hydrocarbon wax having a melting point from 80 o C to 150 o C, as determined by ASTM D87; polyethylene having a melting point from 80 o C to 150 o C, as determined by ASTM D87.
  • FIG. 1 is a sectional view of a power transmission belt including a toothed elastomeric body with a coated fabric substrate adhered to the toothed surface;
  • FIG. 2a illustrates a fabric substrate coated with the coating composition within the scope of examples 1-10 described in the present disclosure;
  • FIG. 2b illustrates a fabric substrate coated with a known coating composition similar to comparative coatings 1-11 described in the present disclosure;
  • FIG. 3 is a sectional view of a portion of a coated fabric substrate according to Example 7.
  • Corresponding reference characters indicate corresponding parts throughout the several views.
  • any numerical range recited herein is intended to include all sub-ranges subsumed therein.
  • a range of "1 to 10" is intended to include all sub-ranges from (and including) the recited minimum value of 1 to the recited maximum value of 10, that is, having a minimum value equal to or greater than 1 and a maximum value of equal to or less than 10.
  • “Wax” is used herein to describe a material formed of a mixture of alkanes of various chain lengths and/or a modified alkane which also includes other functional groups such as esters and/or amines in the chains, and which may demonstrate phase change characteristics, wherein the waxes tend to be solid at room temperature (20 o C), have a melting point above about 40 o C, and are able to absorb heat while showing little volume change during melting.
  • PFAS per- and polyfluorinated substances, including synthetic organofluorine chemical compounds that have multiple fluorine atoms attached to an alkyl chain, for example perfluorinated monomers and oligomers such as perfluorooctanoic acid.
  • Wet coating composition is used herein to describe a liquid coating composition before it is cured.
  • “Dry” coating composition is used herein to describe a coating composition after it is cured.
  • Transport belt or “timing belt” is used herein to describe a mechanical element comprising a loop of flexible materials used to mechanically connect several rotating shafts.
  • “Flexible” as used in connection a substrate which may be coated, means capable of being bent or disposed to yielding.
  • “Non-continuous” as used in connection with a coating means that the coating is not necessarily a continuous film, but may have interruptions, voids, or gaps therein.
  • II. Composition of Coating [0027] The present disclosure provides a PFAS free coating for power transmission belts. The coating composition increases wear resistance and lubrication of a coated transmission belt.
  • the coating composition may comprise of a binder resin, a lubricating component, and a solvent. [0028] A.
  • Binder resins provide adhesion to a substrate and improve the mechanical properties, such as elongation, and may be self-curable or cure with the aid of a curing agent.
  • the binder resin may allow the coating to follow the elongation of a coated belt during operation without cracking or disbanding or suffering thermo-mechanical fatigue.
  • a binder resin is referred to herein interchangeably as a ‘binder’, ‘resin binder’ or ‘binder resin’, ‘base’, or ‘binder system’ and, depending on the amount of lubricating component desired, may provide the bulk of the present coatings when applied to a substrate.
  • the binder resin of the present disclosure may be a polymer binder that includes hydroxyl functional polyester reactive with an isocyanate and polyurethane reactive with a carbodiimide.
  • Water-based polycarbonate PUDs cross-linked with carbodiimide may produce a coating film with a higher melting point than water-based polyester that is closer to the melting point of solvent-based polyurethane.
  • Binders of the present disclosure may be supplied as solvent borne or water borne systems.
  • solvent-free aliphatic polyester polyurethane dispersions aliphatic polycarbonate waterborne polyurethane dispersions, polycarbonate ester polyurethane dispersions, hydroxyl-bearing polyesters, acrylic polyols, aliphatic polyisocyanate resins, aliphatic polyisocyanates, VOC-free polycarbodiimides, and water dilutable, activated, multi-functional poly carbodiimides may be used.
  • the coating composition provided by the present disclosure can comprise a weight percentage of binder resin, for example, from 20 wt. %, 25 wt. %, 30 wt.
  • Binder resin may be present in the cured coating composition, in an amount from 30 wt.%, 35 wt.%, 40 wt.%, 50 wt.% to 60 wt.%, 70 wt.%, 80 wt.%, 90 wt. %, or any range including any two of these values as endpoints, such as 30 wt.% to 90 wt.%, 35 wt.% to 80 wt.%, 40 wt.% to 70 wt.%, or 50 wt.% to 60 wt.%, wherein the weight percent is based on the total weight of the “dry” coating composition.
