| Summary: | 碩士 === 長榮大學 === 職業安全與衛生學系碩士班 === 97 === A systematic study of the influence of the non-halogen phosphorus flame retardant, triphenyl phosphate (TPP), on the physical properties of the Polycarbonate (PC)/ Acrylonitrile-Butadiene-Styrene polymer (ABS) 80%/20% PC/ABS blend was conducted to be proved a better quality.
PC/ABS blend mixing with TPP and other additives were to extrude as grains which were injected as test specimens for further testing on mechanical property, thermal property and flame-resistance nature. Test results then were used to compare with other commercial similar materials.
PC/ABS added more than 13phr of TPP comply with UL94 V-0 grades in this research. As the amount of TPP was increased, melting index (MI) increased, but the impact strength (IZOD), the vicat softening point temperature (SP), the heat distortion temperature (HDT), the tensile strength (TS) and flexural strength (FS) decreased.
Compared to other commercial products on the market, flame-retarded PC/ABS blends have worse heat properties (vicat softening point temperature and heat distortion temperature), but their melting index, tensile strength, and flexural strength are as good as other products on the market. However, their impact strength is higher than other products on the market.
