The invention provides a flame-retardant carpet base material layer and a flame-retardant carpet, the flame-retardant carpet base material layer at least comprises a flame-retardant PET fiber material and a low-melting-point PET fiber material, the flame-retardant PET fiber material adopts phosphorus flame retardant, the mass ratio of the flame-retardant PET fiber material is 60%-80%, and the mass ratio of the low-melting-point PET fiber material is 20%-30%. According to the flame-retardant carpet base material layer provided by the invention, the flame-retardant PET fiber material adopts a phosphorus-based flame retardant and meets the requirements of laws and regulations under two working conditions of flight and land walking, the flame-retardant PET fiber material provides a certain flame-retardant effect, and the low-melting-point PET fiber material plays a role in forming, so that the flame-retardant carpet base material layer has a good flame-retardant effect under the condition that the flame-retardant carpet base material layer meets the aviation high-standard flame-retardant requirement. And the composite material still has good formability and can be suitable for air-ground amphibious manned aircrafts.
本申请提供一种阻燃地毯基材层以及阻燃地毯,该阻燃地毯基材层至少包括阻燃PET纤维材料和低熔点PET纤维材料,阻燃PET纤维材料采用磷系阻燃,且阻燃PET纤维材料的质量占比为60%‑80%,低熔点PET纤维材料的质量占比为20%‑30%。本申请提供的阻燃地毯基材层,阻燃PET纤维材料采用磷系阻燃,满足飞行和陆行两种工况下的法规要求,且通过阻燃PET纤维材料提供一定的阻燃作用,低熔点PET纤维材料起到成型作用,使得阻燃地毯基材层在满足航空高标准阻燃要求的情况下,依然具有良好的成型性,能够适用于陆空两栖载人飞行器。
