INVESTIGATION ON PROPERTIES OF RECYCLED GLASS FIBER REINFORCED FLAME RETARD ANT PBT
Due to its excellent comprehensive properties, glass fiber reinforced flame retardant PBT was widely applied in electrical accessory. In this paper, the glass fiber reinforced flame retardant PBT with five times mold-injection effect on its carboxyl content, characteristic viscosity of PBT and microscopic appearance were studied. The properties of recycled glass fiber reinforced flame retardant PBT including mechanical, electrical and frame retardant properties were well investigated. The results demonstrated that when the recycled glass fiber reinforced flame retardant PBT were multiple processed, its carboxyl content increased while the characteristic viscosity of PBT and the length of glass fiber decreased. After five times mold-injection, all its physical properties decreased, especially the notched impact strength, tensile strength, flexural strength drastically decreased from 75 J/m to 33 J/m, 115.6 MPa to 54.9 MPa, 161.1 MPa to 95.2 MPa, respectively.
