Colorful high-elastoplastic pen and making method thereof

Abstract

The invention discloses a colorful high-elastoplastic pen and a making method thereof. In the making method, 20-40% of polymer is used as a main body, 20-38% of white or colorless solid powder is used as a color carrying body, 2-20% of pigment is used as a dyeing body, and 2-20% of regulating agent is assisted properly; and after evenly mixing, the product disclosed by the invention is obtained by extrusion molding, cooling, solidifying and cutting at the temperature of 120-250 DEG C. The making process of the method is simple and environment-friendly, equipment is compact and convenient for use; the colorful high-elastoplastic pen does not adhere hands, is not broken off, is not faded and is not dyed, and color is clear when the colorful high-elastoplastic pen performs writing; and the colorful high-elastoplastic pen is convenient for carrying and storage, and has wide applicability and reliable safety. Because the pen disclosed by the invention has high elasticity and plasticity, the pen disclosed by the invention does not cause hard damage to a human body when in use; and simultaneously, in the pen, natural compounds or green chemical raw materials are adopted, thus the pen is safe to the human body, does not pollute environment, and is an environment-friendly and safe product.

Description

technical field

[0001] The invention relates to a composition and a preparation method of a novel pen, in particular to a composition and a preparation method of a colored high elastic-plastic pen. Background technique

[0002] A pen 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. At all times and in all over the world, solid pens are not strong enough and easy to break (such as chalk, crayons and oil pastels, etc.), so people usually use a multi-layer combination of "pen holder" and "pen core" to make pencils for use; liquid pens, It is generally used by dipping and writing intermittently (such as brushes, dipping pens), and later made fountain pens and ballpoint pens using capillary tension. All these pens have a series of problems such as making more complicated, inconvenient to use, inconvenient to carry and no...
