Carpet Backing Adhesives Patents (Class 524/915)
  • Patent number: 8466205
    Abstract: The present invention pertains to carpet and methods of making and recycling carpet. In one aspect, the carpet includes: a primary backing which has a face and a back surface; a plurality of fibers attached to the primary backing and extending from the face of the primary backing and exposed at the back surface of the primary backing; an adhesive composition backing; and an optional secondary backing adjacent to the adhesive backing. The method of making carpet includes extrusion coating the adhesive composition onto the back surface of a primary backing to form the adhesive composition backing. The method of recycling carpet can recover one or more polymeric carpet components.

  • Patent number: 5565511
    Abstract: A method of producing a high solids adhesive is provided wherein a buffered latex emulsion, such as, for example, styrene butadiene latex emulsion buffered to a pH of 11.0 using caustic agents, is combined with a non-emulsified mixture of dissolving process oils and tackifying resins and mineral fillers. The resultant adhesive has a solids content greater than previously achieved in the industry and has exceptional adhesive characteristics such as increased bond strength, improved durability, better aging, faster drying, improved water resistance and improved freeze resistance. High solids content is achieved by taking advantage of the excess emulsifiers in the latex emulsion and adding the remaining constituent components directly to the stabilized latex emulsion.
