The invention discloses a piece of
moisture-proof highly-breathable non-woven
wallpaper and a preparation method thereof. The method comprises the following steps: respectively placing waste fibers,
plant fibers and chemical fibers into a first stock chest, a second stock chest and a third stock chest; adding a packing, a
sizing agent and a
wet strength agent; forming a non-woven
wallpaper upper layer through the
plant fibers; respectively placing mixed solutions in the three stock chests into fluffers to be defibered, respectively adding a retention aid into the stock chests filled with the mixed stock after defibering, uniformly stirring the mixtures, and then adopting the inclined wire
processing technology to achieve layered stock intake; respectively feeding the three
layers of stock into flow boxes, subjecting the stock to water
filtration and retention on a forming wire to form a wet paper web,
drying to obtain an upper layer of body paper, an intermediate layer of body paper and a lower layer of body paper, which are different from one another,
coating paste
starch among the body paper, adding a
flame retardant, and then
drying to obtain the
moisture-proof highly-breathable non-woven
wallpaper. The non-woven wallpaper has favorable air permeability,
moisture resistance and
fungus resistance, and is good in stability, resistant to
impact, free of deformation and excellent in coverage.
