The invention relates to a method for preparing a
konjac glucomannan composite
humidity conditioning agent. The method comprises the following steps of: (a) weighing
sodium hydroxide, adding the weighed
sodium hydroxide to deionized water for dissolving, adding
acrylic monomers into
sodium hydroxide liquid, and uniformly stirring at the temperature of 65-70 DEG C; (b) weighing
potassium sulfate, activated
halloysite with the particle size of 200 meshes,
konjac glucomannan, nano silver-loaded
antimicrobial powder, N,N'-
methylene-bis-
acrylamide and
urea, sequentially adding the weighed
potassium sulfate, activated
halloysite,
konjac glucomannan, nano silver-loaded
antimicrobial powder, N,N'-
methylene-bis-
acrylamide and
urea into a reactor containing the liquid obtained in the step (a), and carrying out reaction for 20-30 min at the temperature of 65-70 DEG C, thereby obtaining a viscous
solid product; and (c) after the
polymer obtained in the step (b) is cooled to
room temperature,
drying for 4-5 hours at the temperature of 145-150 DEG C, carrying out
decomposition and foaming through the
urea so as to obtain a porous
humidity conditioning material, and crushing the porous
humidity conditioning material for 2-3 min by using a
crusher, thereby obtaining humidity conditioning material
powder with the particle size of 100-200 meshes. According to the method for preparing the konjac
glucomannan composite humidity conditioning agent, the konjac
glucomannan composite humidity conditioning agent has the advantages of large
moisture content / capacity, good
relative humidity stability, simplicity and convenience in preparation, low cost, good effect, environmental friendliness and no
pollution.
