Abstract

The invention discloses a water-base environment-friendly crayon which contains the following components in parts by weight: 50-100 parts of oxidized paraffin, 10-20 parts of paraffin, 100-150 parts of titanium dioxide, 50-70 parts of stearic acid, 20-30 parts of modified phenolic resin, 10-20 parts of polyethylene glycol, 5-10 parts of glycerinum, 20-30 parts of natural pigment and 5-10 parts ofcyclodextrin. The water-base environment-friendly crayon provided by the invention has a basic function of scrubbing with water and is capable of enhancing the plasticity and strength of the substrate; the softening point of stearic acid is increased through the reaction between polyethylene glycol, hydroxide radicals of glycerinum and modified phenolic resin and the interpenetration with stearicacid; the crayon disclosed by the invention writing on a rubber material is smooth and easy, is in bright color, is stable after solidification and is high in hardness.

Description

technical field [0001] The invention relates to the technical field of stationery products, in particular to a water-based environment-friendly crayon. Background technique [0002] Crayon is a pen-like material that can be used for painting, writing, marking and other purposes obtained by uniform mixing and casting of waxy base material and pigment. The crayons on the current market are generally paraffin wax, pigments, calcium carbonate, vaseline etc. with regard to their raw materials, wherein the paraffin wax component accounts for about 70%, the pigment accounts for 5-10%, calcium carbonate 10%, and vaseline 10%. After mixing, heat and stir, pour into the mold and shape. Although this kind of crayon is easy to prepare, it is not easy to adhere when writing on rubber and tires, and because most of the tires are dark black, the color rendering effect is not obvious. After a few days, it will become unstable and become soft and loose, and it will be troublesome to clean ...
