In this study, ammonium polyphosphate (APP) was coated on the surface of carbon microspheres (CMSs) to synthesize the CMSs-APP (CA) three-in-one intumescent flame retardant (IFR). Then, CA was coated the surface of polyester fabric (CAP) by flame retardant finishing method to improve the flame retardant of polyester fabric. Morphology, thermal, flame retardant and other properties of CAP was characterized by SEM, TG, LOI, UL94 and CONE. The results show that when two layers of flame retardant (CMSs-APP) coated on polyester fabric (CAP2), the LOI value of CAP2 was 28.1% and the burning rating reached B1 class with no droplet drop during the UL94 test. The residue char has increased by 22.2%. The CA coating significantly reduced the heat release rate (HRR) and total heat release (THR) of the polyester fabric, with the HRR reduced by 51.0%, and produced a more stable and compact carbon layer during combustion. Moreover, the coated polyester fabric has excellent washing durability. Overall, CA flame retardant was coated the surface of polyester fabric endowed the polyester fabric with good flame retardant, broadening its scope of application.

在这项研究中，将聚磷酸铵（APP）涂在碳微球（CMS）的表面上，以合成CMSs-APP（CA）三合一膨胀型阻燃剂（IFR）。然后，通过阻燃整理方法将CA涂覆在聚酯织物（CAP）的表面上，以改善聚酯织物的阻燃性。通过SEM，TG，LOI，UL94和CONE对CAP的形貌，热学，阻燃性和其他性能进行了表征。结果表明，当在聚酯织物（CAP2）上涂覆两层阻燃剂（CMSs-APP）时，CAP2的LOI值为28.1％，燃烧等级达到B1级，在UL94测试期间无液滴滴落。残炭增加了22.2％。CA涂层显着降低了聚酯织物的放热率（HRR）和总放热（THR），HRR降低了51.0％，并在燃烧过程中产生了更稳定，更致密的碳层。此外，该涂覆的聚酯织物具有优异的洗涤耐久性。总的来说，CA阻燃剂被涂覆在聚酯织物的表面，赋予聚酯织物良好的阻燃性，拓宽了其应用范围。
