  • Patent number: 12006388
    Abstract: A composite material is provided. In some aspects, the composite material may include a combination of a thermoplastic resin mixed with a polypropylene-graft-maleic anhydride (PPgMA). Carbon particles may be mixed in the combination. In this way, the composite material may include between 80 wt. % and 90 wt. % of the thermoplastic resin, between 0.5 wt. % and 15 wt. % of PPgMA, and between 0.1 wt. % to 7 wt. % of carbon particles. Carbon particles may have exposed carbon surfaces with carbon atoms bonded to molecular sites on adjacent PPgMA molecules. At least some carbon atoms may be oxidized with one or more of oxygen-containing groups. Oxidation of carbon atoms may be associated with an increase in at least some PPgMA molecules chemically bonding with adjacent carbon atoms per unit volume. In this way, interaction between carbon atoms and PPgMA molecules may maintain composite material density within +/?3% of thermoplastic resin density.

  • Patent number: 11958955
    Abstract: Hybrid spray foams utilize a urethane reactant, a crosslinker, and an (optional) epoxy and/or acrylic resin along with a blowing agent and rheology modifier to produce a quick-setting foam that remains in place until the foam forms and cures. The urethane reactant may be formed as an adduct with or without the use of isocyanate chemistry. In some embodiments, the polyurethane oligomer is made by reacting cyclocarbonates and di- or polyamines, while in other embodiments the polyurethane backbone employs the use of commercially available capped or blocked urethane oligomers made by any method. The oligomers contain reactive groups, typically at the oligomer ends, that crosslink with crosslinkers or with acrylic or epoxy resins to form hybrid polyurethane foams. Foams may also contain a plasticizer, and/or a surfactant as well as other optional additives. Methods of making such foams are also provided.
