Abstract: A first composition is disclosed that includes a fire-resistant thermoplastic resin. The fire-resistant thermoplastic resin includes 1-20 wt % of an aryl phosphate, includes 1-20 wt % of a phosphate polymer, and 60%-98% of a (meth)acrylic polymer, including units from at least one monomer, wherein the monomer is chosen from methyl methacrylate, acrylic acid, methacrylic acid, acrylic acid esters, methacrylic acid esters, acrylonitrile and maleic anhydride. The first composition may further include a fabric or a composite material that is embedded with the fire-resistant thermoplastic resin. In some instances, the aryl-phosphate and the phosphonate polymer synergistically reduce an effective heat of combustion, a peak heat release, or a flame time as compared to a second composition that contains only one of the aryl phosphate or the phosphonate polymer.

Abstract: The present disclosure provides a flame retardant and antistatic regenerated polyester wig fiber and a preparation method thereof, and relates to the field of simulated wig technology. A composite flame retardant composed of poly(sulfonyldiphenylene phenylphosphonate) (PSPPP), a derivative of 9,10-dihydro-9-oxa-10-phosphaphenanthrene-10-oxide (DOPO-FT), and 9,10-dihydro-9-oxa-10-phosphaphenanthrene-10-oxide triphosphonitrile (DOPO-TPN), and biomass-derived graphene are subjected to a re-polymerization reaction with an alcoholysis product BHET of a waste PET bottle flake, respectively to obtain an in-situ modified flame retardant regenerated masterbatch and an antistatic regenerated polyester masterbatch. The masterbatches are blended and melt-spun with regenerated polyester, so that the obtained wig fiber has good flame retardant property, better flame retardant coefficient and antistatic property, and a significant antibacterial effect, thereby increasing the safety of the wig. The recycled and regenerated polyester from the PET bottle is utilized, effectively reducing environmental pollution caused by waste polyester, and contributing to resource conservation and sustainable development.
