Problems solved by technology

[0002] Generally, the pencil uses a wooden pen holder, and its material consumes a lot of wood, which is not conducive to environmental protection.
The manufacturing process of wooden pencils is more complicated, polluting, costly, quality control is difficult, the appearance is less changed, the refill is toxic, and it is easy to break
In order to overcome the shortcomings of wooden pencils, there are now plastic pencils, but the ingredients of the pen holder and the refill are unreasonable, the elasticity is poor, children are easy to break when using or playing, the refill is laborious to write, the coloring is poor, and the product higher cost

example 1

[0008] A colored drawing pencil, the pen core is a tough pen core, basically composed of the following components by weight ratio, graphite powder 50, polystyrene (PS) 20, chlorinated polyethylene (CPE) 3, calcium stearate 3. It is basically composed of the following components by weight ratio, thermoplastic elastomer (JEP) 30, polystyrene (PS) 9, talcum powder 80, filler 3.5, crosslinking agent 0.6. The surface of the pen holder is provided with a skin layer, which is mainly composed of thermoplastic elastomer (JEP) with a weight ratio of 4:6. Some additives, such as titanium dioxide, can also be added to improve stability. In addition, industrial toners, such as Lisol Scarlet, can be added to make the surface colorful and beautiful.

Abstract

The invention relates to a drawing color pencil, which comprises a pencil rod and a pencil lead. The pencil is characterized in that the pencil lead is a tough pencil lead, and comprises the following components in parts by weight: 50 to 60 parts of graphite powder, 20 to 30 parts of PS (polystyrene), 3 parts of CPE (chlorinated polyethylene), and 3 to 5 parts of calcium stearate; the pencil rod comprises the following raw materials in parts by weight: 30 to 40 parts of thermoplastic elastomer (JEP), 9 parts of PS, 80 parts of talcum powder, 3.5 parts of fillers and 0.6 part of cross-linking agent. The pencil has the advantages that the elasticity of the pencil rod is good, the breaking is avoided even if the pencil is bent, and the pencil can bounce when falling onto the ground; the pencil lead is tough, so the easiness in breaking is avoided, the writing is fluent, and the coloring performance is good.

Description

technical field [0001] The invention relates to a pencil, in particular to a colored drawing pencil. Background technique [0002] General pencil adopts wooden penholder, and its material consumption wood is big, is unfavorable for environmental protection. The manufacturing process of wooden pencils is relatively complicated, with high pollution, high cost, difficult quality control, little change in appearance, and the pen core is toxic and easy to break. In order to overcome the shortcomings of wooden pencils, there are now plastic pencils, but the ingredients of the pen holder and the refill are unreasonable, the elasticity is poor, children are easy to break when using or playing, the refill is laborious to write, the coloring is poor, and the product The cost is higher. Contents of the invention [0003] The object of the present invention is to aim at the defects of the prior art and provide a colored drawing pencil which is convenient for drawing various colors. ...
