Preparation method of composite dehumidification adsorbent paper sheet prepared from MOF material and lithium chloride

The invention discloses a preparation method of a composite dehumidification adsorbent paper sheet prepared from an MOF material and lithium chloride. The method comprises the following steps: 1) synthesizing a large amount of the MOF material; 2) dipping fiber paper in a mixed solution formed by the MOF material and silica sol so as to form an MOF layer, taking out the fiber paper after the fiber paper is completely wetted, and airing and drying the fiber paper; and 3) dipping the fiber paper with the MOF layer material in a mixed solution formed by polyvinyl alcohol and lithium chloride again, taking out the fiber paper after the fiber paper is completely wetted, and airing and drying the fiber paper to form a lithium chloride layer, thereby obtaining the composite material dehumidification adsorbent paper sheet. According to the adsorbent paper sheet provided by the invention, the equilibrium adsorption capacity of the adsorbent paper sheet can reach 1.8 g/g, a regeneration temperature is 50-80 DEG C, film
