The invention discloses an environment-friendly degradable mesoporous nanofiber non-woven fabric which is prepared from the following raw material in parts by weight: mesoporous fibers, hemp fibers, aluminum hydroxide, magnesium hydroxide, anionic polyacrylamide, tetrabutyl titanate, isopropanol and ethene diamine. The invention discloses a preparation method of the environment-friendly degradablemesoporous nanofiber non-woven fabric, which comprises the following steps: immersing China hemp fibers in a sodium hydroxide solution, carrying out dissociation and separation by using a separator,and carrying out ball milling to obtain primary fibers; uniformly stirring aluminum hydroxide, magnesium hydroxide and water, adding the primary fibers under the stirring state, adding the anionic polyacrylamide, continuously stirring, filtering, and drying to obtain secondary fibers; and dropwise adding tetrabutyl titanate into isopropanol under the stirring state, adjusting a systematic pH value, adding the secondary fibers, continuously stirring, adding the ethene diamine under the stirring state, continuously stirring, filtering, washing, drying, and carrying out airflow stretching, cooling curing, paving and reinforcing to obtain the environment-friendly degradable mesoporous nanofiber non-woven fabric.
