The invention provides loofah
sponge charcoal powder. A preparation method of the loofah
sponge charcoal powder comprises the steps of treating loofah
sponge treatment residues to obtain loofah sponge
powder; activating loofah sponge powder by adopting a
molten salt activating agent consisting of ZnCl2 and AlCl3, and carrying out high-temperature
carbonization treatment on the activated loofah sponge powder; and cooling to
room temperature, cleaning the loofah sponge
charcoal powder, carrying out vacuum suction
filtration, washing the loofah sponge charcoal powder to be neutral, and
drying. The invention further provides a loofah sponge charcoal-based foam material which is obtained by mixing and foaming the loofah sponge charcoal powder and a foaming preparation, and the material can be used as a pillow inner. The invention also provides a loofah sponge charcoal memory sponge pillow. The adopted loofah sponge is loofah sponge treatment residues, and the
utilization rate of the loofah sponge can be effectively increased; moreover, the loofah sponge is activated by adopting the
molten salt activating agent, so that the foaming effect of loofah sponge charcoal and the foaming preparation can be improved, and the
memory foam sponge material and the pillow which are antibacterial, sleep-aiding and good in
moisture dissipation property and have the effects of
tear resistance and yellowing resistance are further obtained.
