Abstract

The invention provides an environment-friendly degradable child colored oiled crayon. The colored oiled crayon comprises the following components the content of which is in mass fraction: 0.3-12% of chromogenic reagent, 6-15% of color-developing agent, 35-53% of emulsifying wax, 15-20% of polyethylene glycol, 12-25% of stearic acid, and 2-15% of talcum powder. The child colored oiled crayon disclosed by the invention overcomes the shortcoming that the existing child crayon is difficult to erase, and has the advantages that after writing, color can be removed by wiping with water, and no trace is left. The colored oiled crayon is dust-pollution-free, environment-friendly, non-toxic and innocuous, and can be not only used as a child crayon, but also used to write on a whiteboard for teaching. The production process is simple and mass production of the crayon is easy to realize.

Description

technical field [0001] The invention relates to writing and drawing utensils, in particular to an environment-friendly and degradable children's colored crayons and a preparation method thereof. The colored crayons can be used not only as children's crayons, but also for whiteboard teaching, can be wiped dry and wet, and can be faded when exposed to water. Background technique [0002] The main components of traditional crayons used by children are paraffin, talcum powder and pigments, and the pigments generally used are non-degradable and harmful to the environment. It is easy to draw on clothes, bed sheets, furniture and other items during children's use, and it is difficult to erase and fade, which may cause the items to be discarded and unsightly. [0003] Due to the above problems, it is urgent to develop an environmentally friendly crayon that can be used for children's daily drawing exercises, is non-toxic and harmless, and can fade with water. Contents of the inve...
