阻燃PP纺粘无纺布的性能研究

研究了阻燃母粒法和整理法制得的阻燃PP纺粘无纺布的力学性能、热性能和阻燃性能。结果表明:阻燃母粒法制得的阻燃PP纺粘无纺布的断裂强力与PP纺粘无纺布的接近,但断裂伸长率要低,后整理法制得的纺粘无纺布的力学性能与PP纺粘无纺布的接近;两种方法制得的阻燃PP纺粘无纺布的热性能均优于PP纺粘无纺布,在1000℃左右时,有24.0%～33.2%的炭残渣,成炭性较好;两种方法制得的阻燃PP纺粘无纺布的阻燃性能良好,其中用阻燃剂B整理后的PP纺粘无纺布其阻燃效果优于阻燃剂A整理的PP纺粘无纺布。     

Preparation and Characterization of Flame-Retardant Viscose Fiber Treated with TAECTP

In this paper, hexachlorocyclotriphosphazene (HCCTP) was used as a raw material to synthesize triaminoethyloxy cyclotriphosphazene (TAECTP). After-finishing method was applied to the preparation of flame-retardant viscose fibers. LOI results showed that TAECTP was intrinsically flame retardant. After burning, inflated carbonized coat was found on the fiber surface. Thermogravimetric analysis (TG) indicated that primary decomposition temperature of the fiber moved up about 30°C, as compared with untreated viscose fiber. Loss on mechanical properties of fibers was insignificant. The introduction of TAECTP was compatible and the flame retardancy of viscose fiber was greatly improved with limited negative impact.     

含磷聚硅氧烷涂覆涤纶织物的结构与性能研究

以甲基三乙氧基硅烷、硅溶胶为成膜剂,磷酸酯M102B为阻燃剂,采用溶胶-凝胶方法制备含磷聚硅氧烷阻燃涂层剂,用于涤纶织物的表面涂覆处理,并对阻燃涤纶织物的结构与性能进行表征。结果表明:随着涂层剂涂覆量的增加,织物的阻燃性能提高,但织物的柔软性能和手感下降;当涂覆量为50.79 g/m2时,涤纶织物的续燃时间为3.7 s,损毁长度为3.5 cm,达到一级阻燃效果;经涂层剂整理的涤纶织物耐水洗性优良,洗涤20次后仍具有一级阻燃效果;涂层剂对涤纶的化学结构、热稳定性及力学性能影响不大。
