Abstract:

The thermodynamic parameters of FRW fire-retardant plywood at different temperatures were measured by dynamic mechanical analysis (DMA) equipment such as storage modulus, loss modulus and loss angle tangent. The influences on the thermodynamic properties of FRW fire-retardant plywood by the FRW fire retardant were analyzed between the FRW fire-retardant plywood and the untreated plywood. The results showed that the transition temperature of FRW fire-retardant plywood's storage modulus was delayed than the untreated plywood. Its value was also higher than the untreated plywood. Meanwhile the glass transition temperature of plywood treated by FRW fire retardant was raised. FRW fire-retardant plywood could keep the better mechanical performances and ability of deformation-resistance at higher temperature and during longer period than the untreated plywood.

Key words: dynamic mechanical analysis (DMA), FRW fire-retardant plywood, FRW fire retardant, thermodynamic performance, glass transition temperature
