Abstract：

First,　Layered　double　hydroxide　(LDH)　was　modified　by　toluene　diisocyanate　(TDI),　2-hydroxyethyl　acrylate　(HEA),　and　LDH-TDI-HEA　was　prepared.　Then　LDH-TDI-HEA　was　modified　by　vinyl　triethoxysilane　(VTES),　and　LDH-TDI-HEA-VTES　composites　were　obtained.　Finally,　acrylate　was　modified　by　LDH-TDI-HEA-VTES,　and　flame　retarded　LDH-TDI-HEA-VTES-Acrylate　composites　were　successfully　synthesized　by　in　situ　polymerization.　The　structures　of　LDH,　LDH-TDI-HEA,　LDH-TDI-HEA-VTES　and　LDH-TDI-HEA-VTES-Acrylate　composites　were　characterized　by　Fourier　transform　infrared　spectra,　X-ray　diffraction,　X-ray　photoelectron　spectroscopy　and　Scanning　electron　microscopic.　The　effect　of　LDH-TDI-HEA-VTES　content　on　the　thermal　stability,　mechanical　properties,　adhesion　properties　and　flame　retardant　properties　of　LDH-TDI-HEA-VTES-Acrylate　composites　was　studied.　At　the　same　time,　the　thermal　stability,　mechanical　properties,　adhesion　properties　and　flame　retardant　properties　of　LDH-Acrylate　composites　and　LDH-TDI-HEA-VTES-Acrylate　composites　were　also　studied.　The　experimental　results　showed　that　with　the　increasing　of　LDH-TDI-HEA-VTES　content,　the　thermal　stability,　mechanical　properties,　flame　retardant　properties,　and　shear　resistance　of　LDH-TDI-HEA-VTES-Acrylate　composites　were　improved,　while　the　tack　and　180°　peel　strength　decreased.　When　the　content　of　LDH-TDI-HEA-VTES　was　7　wt%,　the　LOI,　after-flame　time　and　the　UL　94　grade　of　LDH-TDI-HEA-VTES-Acrylate　composites　were　27%,　0　s,　and　V-0,　respectively.　LDH-TDI-HEA-VTES-Acrylate　Composites　have　good　flame　retardant　properties.　At　the　same　time,　the　flame　retardant　mechanism　of　LDH-TDI-HEA-VTES　composites　was　also　analyzed.　©　2019
