Abstract

The invention discloses a wipeable colored plastic crayon material and an application thereof. The wipeable colored plastic crayon material comprises the following components in parts by weight: 30-60parts of paraffin, 5-10 parts of stearic acid; 3-15 parts of polypropylene; 1-5 parts of a polyolefin elastomer; 1-5 parts of a wipeable polymer; 20 to 40 parts of filler; 3-10 parts of a pigment; and 1-5 parts of a pigment dispersant. According to the invention, the polypropylene, the polyolefin elastomer and the wipeable polymer are compounded, so that the material is endowed with excellent wipeable performance under the condition that the overall material does not influence other properties after being combined with stearic acid and paraffin; the addition of the resin raw material components does not affect the writing performance and coloring performance of the crayon material, but also contributes to the drawing performance of a crayon product, so that the crayon product is very smooth in writing and excellent in coloring performance; meanwhile, the tedious step that in the prior art, color paste needs to be independently ground and dispersed and then can be mixed with other components to manufacture the crayon is avoided, the preparation process is simplified, and the production and manufacturing cost is reduced.

Description

technical field [0001] The invention relates to the field of lead materials, in particular to an erasable color plastic crayon material and its application. Background technique [0002] As a painting tool, crayons have been widely used at present, and they can have dozens of colors. Crayons have no permeability and are fixed on the screen by adhesion. Get composite colors. It is an ideal tool for children to learn color painting, and some painters also use it for sketching and color recording. At present, ordinary crayons are made of paraffin and toner. Due to the low softening point of paraffin crayons, the texture of ordinary crayons is soft, with a sticky feel, easy to break when used, and accompanied by a lot of debris. , can not be wiped, not smooth when drawing, poor coloring, and when preparing crayon materials, many preparation processes must be passed through, the process is quite complicated and the production cost is very high. [0003] At present, the fractur...
