摘要

通过共沉淀法在聚磷酸铵(APP)表面原位生长MOFs,设计了一种多级MOFs结构膨胀阻燃剂Co-MOF@γ-CD-MOFs@APP(其中CD为环糊精)。通过傅里叶红外光谱和扫描电子显微镜表征了其新结构和形貌。通过垂直燃烧试验仪和氧指数仪对制备的水性聚氨酯涂层进行了燃烧行为的评估。结果表明:当Co-MOF@γ-CD-MOFs@APP的添加量为15%时,垂直燃烧等级通过V-0级,LOI高达36.7%。PP/Co-MOF@γ-CD-MOFs@APP形成更加致密的炭层对烟雾和热量起到较好的抑制作用。引入多级MOFs结构为构建多组分膨胀阻燃体系提供了新思路。

Abstract

A multi-level MOF structure expansion flame retardant Co-MOF@γ-CD-MOFs@APP (where CD denotes cyclodextrin) was designed by in-situ growth of MOFs on the surface of ammonium polyphosphate (APP) using coprecipitation method.The new structure and morphology were characterized by Fourier transform infrared spectroscopy and scanning electron microscopy.The combustion behavior of the prepared waterborne polyurethane coating was evaluated using a vertical combustion tester and an oxygen index meter.The results indicated that when the addition amount of Co-MOF@γ-CD-MOFs@APP was 15%,the vertical combustion level passed through V-0 level,and the LOI was as high as 36.2%.The formation of a denser carbon layer by PP/Co-MOF@γ-CD-MOFs@APP had a better inhibitory effect on smoke and heat.Introducing a multi-level MOF structure provides a new approach for constructing multi-component expansion flame retardant systems.
