Hydroxyl terminated poly(dimethylsiloxane) crosslinked by expanded vermiculite and its flame retardant performance optimization

  • Received Date: 2015-10-27
  • Expanded vermiculite (EV) doped poly(dimethylsiloxane) (PDMS) (EV-PDMS) was prepared through two steps of condensation reactions, in which hydroxyl terminated poly(dimethylsiloxane) was as main part, high temperature EV was as additive, and tetraethoxy-silicane (TEOS) was as coupling agent.And the flame reatardant performance of EV-PDMS was studied.Detections of attenuated total reflectance infrared spectrum (ATR-IR), water contact angle, and scanning electron microscope (SEM) revealed that, EV flakes homogeneously dispersed into PDMS, and crosslinked with PDMS through Si-O-Si covalent bonds; the resultant EV-PDMS elastomer maintained a highly hydrophobic surface.Mechanical properties revealed that, after addition of 60 copies EV, tensile strengths, Young's moduli, and Shao's hardness respectively increase to 4.50, 1.97 and 2.17.Combustion tests revealed that, after addition of 5 copies of decabromodiphenyl oxide (DeDBE) and 5 copies of aluminum hydroxide, flame retardant properties of EV-PDMS reached to FV-0 class, and their limited oxygen indexes (LOI) reached to 69.5%.
