The invention discloses amacromolecular
polymer colored clay and a preparation method thereof, and relates to the technical field of
colored clay. The macromolecular
polymer colored clay is prepared from the following components in percentage by weight: 1 to 35 percent of a macromolecular dihydric
alcohol, 15 to 50 percent of diisocyanate, 1.5 to 15 percent of a chain
extender, 0.1 to 2 percent ofa colored micromolecular dihydric
alcohol, 0.1 to 5 percent of a cross-linking agent, 0.1 to 1 percent of a
wetting agent and 1 to 20 percent of water. The macromolecular
polymer colored clay prepared by the invention belongs to a
high polymer material, and has the properties of safety, no
toxicity, high
ductility, high elasticity, low
viscosity and the like. Meanwhile, the micromolecular structures are grafted to the polymer, so that the macromolecular polymer colored clay has the characteristics of rich colors, good permeability and the like. As the
wetting agent is added into the macromolecular polymer colored clay, the
water retention effect is good, and the macromolecular polymer colored clay can be repeatedly used.
