The invention provides a water erasable fading artistic oil painting stick and a preparation method thereof. The water erasable fading artistic oil painting stick comprises the following components by weight: 23-51 parts of organic wax substrate, 12-30 parts of inorganic mineral filler, and 5-15 parts of environmentally friendly degradable pigment, wherein the organic wax substrate comprises wax, oil, grease, and a conditioning agent, the filler comprises a basic filler and a functional filler, and the environmentally friendly degradable pigment comprises a color former and a color developing agent. The water erasable fading artistic oil painting stick overcomes the defects that the water erasable fading crayon for children is high in hardness, is not smooth to write with, and is not favorable for use by the children, has the characteristics of high coloring power and excellent smoothness, is safe and environmentally friendly, does not contain heavy metals, and fades without traces after being erased with water; meanwhile, the artistic oil painting stick fades without traces after being erased with water, does not cause dust pollution, can be used for scribbling by the children, and can also be used writing in whiteboard teaching. The production process is simple, and the water erasable fading artistic oil painting stick is easy to produce in batches.
Description
technical field [0001] The invention relates to writing and painting utensils, in particular to a water-rubbing and fading color oil painting stick and a preparation method thereof. Background technique [0002] The main components of traditional children's crayons are paraffin, talcum powder and pigments. Generally, the pigments used are non-degradable inorganic mineral pigments. These pigments mostly contain arsenic (As), barium (Ba), lead (Pb), mercury (Hg) , antimony (Sb), chromium (Cr), cadmium (Cd) and other heavy metal elements, long-term use will cause harm to the human body. At the same time, when such products are painted on the surface of clothes, bed sheets, walls, and furniture, it is difficult to erase, which brings great troubles to young mothers. Invention patents "A blue solid writing pen (CN102964925B, authorized announcement date: 2014.04.09)" and "environmentally friendly and degradable children's colored crayons and their preparation method (CN102964926...
