Problems solved by technology

Special attention should be paid to the preservation of the pencil lead, and the more common pen holders on the market are still made of wood or paper. If the pen is accidentally dropped into water during use or the pen is placed in a humid environment, the pencil lead will easily melt. It will be a phenomenon that the pencil lead is melted and damaged while the pen barrel is intact, which is a great waste of natural resources

Abstract

The invention relates to the technical field of stationery, in particular to a colored pencil refill, the raw materials of which are calculated in parts by weight: 30-50 parts of sodium thiosulfate, 10-20 parts of talcum powder, 3-6 parts of carboxymethyl cellulose, 8-16 parts of plant pigment, 2-4 parts of food-grade paraffin, 5-15 parts of medical stone powder, 5-12 parts of polyethylene glycol, and 1-3 parts of clove oil. It is green and environmentally friendly and will not cause harm to the human body. It has bright colors, smooth and clear writing, no dross, can be cleaned effectively after being wiped with water, has a fragrant smell, and has good antibacterial functions.

Description

technical field [0001] The invention relates to the technical field of stationery, in particular to a colored pencil refill. Background technique [0002] In the prior art, ordinary pencil refills used for writing, drawing and painting are basically composed of graphite powder, which has disadvantages such as incomplete erasing, unsanitary, and difficult cleaning when it gets on hands, which is not good for the health of users; The raw materials and processes of the existing colored pencil cores are complicated, and the raw materials pollute the environment, and the written handwriting cannot automatically fade, so it is not suitable for occasions that do not need long-term storage such as temporary marks and calligraphy and painting exercises. [0003] In addition, colored pencil cores are mostly water-soluble substances. Special attention should be paid to the preservation of the pencil lead, and the more common pen holders on the market are still made of wood or paper. I...
