Abstract

The invention belongs to the field of stationery commodities, and particularly relates to a magnetic writable crayon which comprises the following components in parts by mass: 10-15 parts of stearamide, 1-2 parts of stearic acid, 3-5 parts of glycerol, 2-5 parts of polyethylene glycol, 30-35 parts of solid paraffin, 5-10 parts of polyethylene wax, 5-10 parts of metal magnetic powder, 5-10 parts of polyvinyl alcohol and 5-8 parts of pigment. The problem that the crayon is single in function is solved, the crayon is endowed with magnetism through the metal magnetic powder, writing and drawing of the crayon are kept, the crayon has magnetism, and it is convenient for teachers and children to arrange and temporarily place the crayon.

Description

technical field [0001] The invention belongs to the field of stationery, in particular to a magnetically writable crayon. Background technique [0002] Crayon is a tool commonly used by children when painting. It has rich colors and is loved by children. Children can use their imaginations to create creative works while painting. Crayon drawing is an art form widely used in the painting of teenagers and children. It can be used to draw still lifes, landscapes, and figures. It is very popular among students because of its convenience, speed, simple tools and artistic appeal. The production process of crayons is also relatively simple. Generally, the main components of crayons are paraffin wax and pigments. Most of the pens that mix pigments in wax are cast. The current crayons have single functionality, and although they have a certain drawing effect, the actual use experience is relatively poor. Therefore, the market needs multifunctional crayons badly. Contents of the i...
