Effect of Flame Retardant on Combustion and Mechanical Properties of Bamboo-Fiber Based Composites
Abstract:
Bamboo fibrosis veneers were impregnated with diammonium hydrogen phosphate, and the content of diammonium hydrogen phosphate was 8%, 13% and 17%, respectively. Then bamboo-fiber based composites were prepared with PF resin adhesive. Combustion and mechanical properties of these fire retardant bamboo-fiber based composite were measured. The result showed that: 1) with the increase of diammonium hydrogen phosphate content, combustion properties increased while mechanical properties fell down, 2) when the diammonium hydrogen phosphate content reached 17%, the heat release rate, total heat release, effective heat of combustion, mass loss rate and ignition time went down by 70.1%, 68.8%, 68.5%, 32.0% and 27.1%, compared with the untreated bamboo-fiber based composites, meanwhile, 3) the MOR was 159.5MPa, MOE was 21241.5MPa and IB was 3.51MPa.
