Problems solved by technology

[0002] With the rapid development of the global economy and the improvement of people's material living standards, ideas and concepts are constantly changing, and the requirements for stationery are constantly seeking new ideas and changes. Today's pencils have always followed the original old tradition. For hundreds of years, There has not been much change, especially in developing countries like our country, which has continued to use the old tradition of black lead core wrapped wood skin rods. There has not been much change in appearance and shape, and it cannot meet the diverse needs of people. Sometimes it is necessary to use some fluorescence to mark in the dark, and some add fluorescent powder to the pencil lead to make the pencil lead brittle and easy to break

Abstract

The invention discloses a fluorescent pencil lead, which comprises, by weight part, 10-15 parts of clay, 40-50 parts of graphite, 10-15 parts of pigment powder, 2-4 parts of sodium carboxymethylcellulose, 8-12 parts of a colourant, 5-10 parts of an adhesive, and 10-20 parts of photoinduced energy storage noctilucent powder. The written handwriting emits fluorescence in the dark. The manufactured pencil lead writes smoothly, is not prone to generate slag, is high in adhesive force, and is not likely to be broken.
