Abstract

The invention relates to a method for preparing a flame-retardant, smoke-suppressing and fatliquoring agent containing a metal-organic framework UiO-66 composite material. A single castor oil fatliquoring agent is easy to deposit grease during fatliquoring, resulting in poor thermal stability, easy migration, and flammability. The invention introduces the metal organic framework UiO-66 material and the acetone modified hydrotalcite into the castor oil fatliquoring agent, and utilizes the organic-inorganic hybrid structure of the metal organic framework material and the lamellar structure of the hydrotalcite to jointly improve the flame retardant performance. The UiO-66(Zr / Cu) prepared by the present invention contains organic-inorganic components, no organic modification is required, the process is simple, energy saving and time-saving; the prepared A-MgAl-CO 3 ‑ ‑LDH has good biocompatibility with castor oil, which can effectively reduce the agglomeration of hydrotalcite and improve its dispersion in castor oil.

Description

technical field [0001] The invention relates to a method for preparing a flame retardant, in particular to a method for preparing a flame-retardant, smoke-suppressing and fatliquoring agent containing a metal-organic framework UiO-66 composite material. Background technique [0002] Castor oil is a cheap, non-toxic and easily biodegradable renewable resource, which is widely used in the field of leather. The castor oil fatliquoring agent prepared from castor oil has better softness of crust leather after fatliquoring, and can improve physical and mechanical properties to a certain extent. However, castor oil fatliquors tend to deposit oil during fatliquoring, resulting in poor thermal stability, easy migration, and flammability. Therefore, it is particularly important to develop a flame-retardant atomized fatliquoring agent. [0003] Metal-organic framework material MOF is a new type of porous material with high specific surface area, abundant active sites and easy modifica...
