以聚氨酯(PU)为囊材,以聚磷酸铵(APP)和三聚氰胺焦磷酸盐(MPP)为芯材,制备出了共微胶囊化阻燃剂(M(A&M)),通过红外光谱等对M(A&M)的核壳结构进行表征,证明阻燃荆被PU完全包覆了。将M(A&M)与聚丙烯(PP)熔融共混,制备了阻燃聚丙烯复合材料,并对复合材料的阻燃性、耐水性和热稳定性进行了研究。结果表明:当APP/MPP为3/1时,复合材料的阻燃性能最佳,且经过水处理后PP/M(A&M)样条的阻燃性基本不变,通过SEM观察到,PP/M(A&M)体系在燃烧后能生成更加连续和致密的炭层。 Microcapsule flame retardant (M (A & M)) was prepared with polyurethane (PU) as the core material and ammonium polyphosphate (APP) and melamine pyrophosphate (MPP) as the core material. M (A & M) core-shell structure was characterized to prove that flame retardant Jing PU completely coated. The flame-retardant polypropylene composite was prepared by melt blending M (A & M) and polypropylene (PP), and the flame retardancy, water resistance and thermal stability of the composite were studied. The results showed that the flame retardancy of the composites was the best when the APP / MPP was 3/1, and the flame retardancy of PP / M spunbonds remained unchanged after water treatment. The SEM results showed that the PP / The M (A & M) system produces a more continuous and dense layer of carbon upon combustion.
