Problems solved by technology
[0004] At present, there are three main types of colored clay on the market: the first one uses flour as the main material to add pigments and additives. This kind of colored clay has poor wettability, easy pulverization, and poor repeatability.
The second type uses rubber and filler as the main material, adding binders, additives, etc. This kind of colored clay is too viscous and easy to stick to hands
These color muds have problems such as poor temperature adaptation, easy pulverization, poor repeatability, poor safety, and poor hand feeling.

Abstract
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.
Description
technical field [0001] The invention belongs to the technical field of colored clay, and in particular relates to a macromolecular polymer colored clay and a preparation method thereof. Background technique [0002] Color clay is a kind of educational toy used by teenagers to make creative shapes, but its craftsmanship and material are much improved compared to plasticine, and it is soft and not sticky. Adding an appropriate amount of water after the color clay dries can restore its softness, which has an environmental protection effect and is suitable for kneading creative works. It is of great help to children's thinking and creativity. [0003] Generally speaking, colored clay needs to meet the following requirements: First, it can be used repeatedly. After each child finishes the handwork, he can use water to restore its softness, which is convenient for the next use. Second, it is safe and non-toxic. Since the colored mud is mainly for children to play with and has di...
