Reinforced flame-retardation PBT/PA6 composite material and preparation method thereof

A disclosed reinforced flame-retardation PBT/PA6 composite material comprises the following compositions in parts by mass: 28.2-35.3 parts by mass of PBT, 10-15 parts by mass of PA6 , 10-15 parts by mass of modified TPU, 0.5-2 parts by mass of amino-modified silicone oil, 0.6-1.2 parts by mass of an amino silane coupling agent, 20-30 parts by mass of glass fiber, 17-18 parts by mass of a composite fire retardant, and 0.3-0.6 parts by mass of an anti-oxidant. The invention also discloses a preparation method for the above reinforced flame-retardation PBT/PA6 composite material. According to the technical scheme, the compatibility of PBT with PA6, and PBT and PA6 with glass fiber is improved, and the composite material with relatively high mechanical properties and good flame retardation performance and processing property is obtained, is applied to automobile electrical appliance connectors, and is adaptable to relatively severer driving environment.
