The invention discloses an anti-
sedimentation agent added into building
coating and a preparation technology. According to the anti-
sedimentation agent added into the building
coating and the preparation technology, the anti-
sedimentation agent is prepared from the following raw materials in parts by
mass: 20 to 25 parts of de-ionized water, 0.4 to 0.6 part of a dispersant, 4 to 6 parts of an anti-sedimentation agent, 0.7 to 1.1 parts of a
preservative, 0.3 to 0.5 part of a pH (Potential of
Hydrogen) stabilizing agent, 0.2 to 0.5 part of a de-
foaming agent, 14 to 20 parts of
pigment and filler, 65 to 75 parts of waterborne hydroxyl dispersion, 45 to 55 parts of resin, 2 to 4 parts of a curing agent, 45 to 55 parts of hydrophilic modified polyisocyanate, 55 to 65 parts of
methyltrimethoxysilane, 18 to 24 parts of silica
sol and 75 to 85 parts of elastic
emulsion. The
coating disclosed by the invention has the beneficial effects that the coating has the advantages of environment protection, no ignition under fire, no expansion, no emission of
smoke and long quality guarantee period at
room temperature; the building coating has stable components and a good
adhesion force and is convenient to construct; the anti-sedimentation agent is directly added into the coating through a special
processing manner, so that the coating has a better
wetting and dispersion function; and the leveling property and the anti-sedimentation effect are more obvious.
