The invention discloses
machine-spraying light-weight plastering
mortar and a preparation method thereof. The
machine-spraying light-weight plastering
mortar is prepared from the following componentsin parts by
mass: 130 to 200 parts of ordinary
silicate cement, 60 to 150 parts of hydrophobic lightweight aggregate, 2 to 5 parts of hydrophobic re-dispersible latex
powder, 1 to 2 parts of hydrophobic agent, 0.5 to 1 part of HPMC (hydroxypropyl
methyl cellulose), 2 to 5 parts of
polyvinyl alcohol, 0.5 to 1 part of
xanthan gum, 1 to 2 parts of
hydrate aluminum-
magnesium silicate, 3 to 5 parts ofbentonite, 0.5 to 1 part of PP (
polypropylene) fibers, 5 to 6 parts of expanded
vermiculite, 10 to 50 parts of slaked
lime, 600 to 700 parts of yellow sand, and 0.5 to 1 part of
starch ether. The
machine-spraying light-weight plastering
mortar can be sprayed by a machine, so that the working efficiency of the wall plastering can be greatly increased and is five times or above of the manual construction speed, and the construction period is shortened. The problems that the traditional manual plastering construction efficiency is low, the consumption of materials is vast,
dust pollution exists in the field, and the labor cost is increased can be solved; and the machine spraying construction quality is good, the safety performance is high, and no bubble or dropping can be produced.
