摘　　要：利用双酚芴(BPFL)与苯基磷酰二氯(BPOD)合成的磷基阻燃剂(FHPLC)接枝水性聚氨酯(WPU)制成磷基-WPU阻燃剂(FHWPU)阻燃剂,对棉织物进行阻燃涂层,探讨FHWPU对棉织物阻燃涂层的可行性。测试表明:有机磷可有效接枝至FHWPU阻燃剂上,且FHWPU阻燃剂的黏度随BPFL质量占比增加而增加,其涂层可使棉织物表面形成致密FHWPU层,并改善织物力学性能与阻燃性能,且织物力学性能与阻燃性能增幅随BPFL质量占比而减缓。当BPFL质量占比为2.5%左右时,涂层织物已达难燃级别。分析认为:利用BPFL与BPOD合成的FHPLC接枝WPU制成FHWPU对棉织物阻燃涂层具有可行性。Phosphorus-based flame retardant(FHPLC)was synthesized by using bisphenol fluorene(BPFL)and phenylphosphoyl dichloride(BPOD)as raw materials and then grafted onto waterborne polyurethane(WPU)to form a type of phosphate-based waterborne polyurethane(FHWPU)flame retardant.The resultant flame retardant was used for the flame-retardant coating of cotton fabrics.The feasibility of FHWPU on the flame retardancy of the flame-retar-dant coating of cotton fabrics was investigated.The results indicated that organophosphorus could be effectively grafted onto the FHWPU flame retardant,and the viscosity and particle size of the FHWPU flame retardant increased with an in-crease in the mass proportion of BPFL.The flame-retardant coating formed a dense FHWPU layer on the surface of cot-ton fabrics,resulting in an improvement in the mechanical and flame-retardant properties of cotton fabrics.The incre-ments of the mechanical and flame-retardant properties were depressed with a decrease in the mass proportion of BPFL.The coated cotton fabrics reached a non-flammable level at a BPFL mass proportion of about 2.5 wt%.The results indi-cated that the FHWPU flame retardant was feasible for the flame retardancy of the coating of cotton fabrics.
