Colored high-elasticity antibacterial and environment-friendly crayon

Abstract

The invention relates to a colored high-elasticity antibacterial and environment-friendly crayon. The crayon contains the following materials in percentage by weight: 35%-45% of a high-molecular polymer, 5%-10% of emulsifying wax, 25%-35% of white or colorless solid powder, 5%-10% of a traditional Chinese medicine extract, 7%-14% of a color developing agent, 1%-10% of a colorant, 1%-10% of stearic acid and 1%-10% of an adhesive, wherein the traditional Chinese medicine extract contains common threewingnut root, liquorice, honeysuckles, flos genkwa, mother chrysanthemum and vanilla in a weight ratio of 1 to (1.2-1.5) to (0.8-1.2) to (1-1.5) to (1.7-1.9) to (0.7-0.9). By adding a thermoplastic high-molecular material, the crayon has very good elasticity and is unlikely to be bent; by adding the traditional Chinese medicine extract, the crayon has an antibacterial function; the components of the crayon are non-toxic and harmless, so that the crayon is suitable for being used by children.

Description

technical field [0001] The invention relates to the technical field of chemical materials, in particular to a colored high-elastic antibacterial and environment-friendly crayon. Background technique [0002] A crayon is a tool for writing calligraphy and painting. It disperses the pigment in a solid or (and) liquid medium, and adheres to the surface of the solid material evenly and meticulously with the help of the medium. It can have dozens of colors; but the crayon does not have Permeability is fixed on the screen by adhesion; crayons are mainly used by children, so their main defect is that the carcinogens such as aromatic hydrocarbons produced by raw materials exceed the standard, which is harmful to children's health; Once bent during use, it will be broken, which is not conducive to children's use; in order to overcome the above defects, some water-soluble crayons have been released on the market, such as the Chinese invention patent document (application number: 20091...
