Abstract
In order to solve the problems that solid flame retardant buoyancy materials used in oil products storage and transportation generate environmental pollution and have unsatisfactory flame retardancy,a novel environmentally friendly and non-toxic biomass flame retardant buoyancy material is synthesized by using hollow glass beads,microcrystalline cellulose,phytic acid solution as matrix,carbon source,acid source and air source,respectively.The material's morphology,limited oxygen index,density,volume electrical resistivity,mechanical strength,thermal insulation and inhibition to oil products volatilization are characterized.Results show that the limited oxygen index is 53%,the minimum density can reach 0.469 g·cm-3,the volume electrical resistivity is 2.178 × 107 Ω·m,the maximum compressive strength is 512 kPa,and the inhibition rate to oil products volatilization exceeds 97%.This biomass material has an excellent flame retardancy,high mechanical strength,good inhibition to oil products volatilization,degradability,etc.,and can meet the requirements for flame retardancy material used in the oil products storage and transportation process.
