Abstract
MgFeGa-layered triple hydroxides (MgFeGa-LTH) were synthesized by co-precipitation method. On the basis of molded polyurethane (PU), the composites (PU)/MgFeGa-LTH were prepared, the effect of particle size of MgFeGa-LTH on flame retardancy and mechanical characteristics of composites was investigated. It has been determined that the introduction of MgFeGa-LTH particles 3.5 μm in size results in a more substantial improvement of fireproof and mechanical characteristics of the composites than the introduction of particles 0.06 μm in size.
