Elastic plastic pencil with strong dyeing property

Abstract

The invention relates to an elastic plastic pencil with strong dyeing property. The elastic plastic pencil with strong dyeing property comprises a penholder and a pencil core, and is characterized in that the pencil core is a tough pencil core which is basically composed of the following components in parts by weight: 50 parts of graphite powder, 25 parts of polystyrene (PS), 8 parts of polyethylene (PE), 3 parts of chlorinated polyethylene (CPE), 3.5 parts of calcium stearate and 3 parts of octadecanamide; the penholder is an elastic penholder which is basically composed of the following components in parts by weight: 25-30 parts of thermoplastic elastomer (JEP), 8.5 parts of polystyrene (PS), 60 parts of talcum powder, 2.5 parts of bulking agents, 0.4 parts of cross linking agents and 0.4 parts of foaming agents. According to the elastic plastic pencil with strong dyeing property, the penholder is very good in elasticity, does not break in bending, and even can rebound when being thrown on the ground; the pencil core has toughness, and is not easy to break, fluent in writing and strong in dyeing property.

Description

technical field [0001] The invention relates to a pencil, in particular to an elastic plastic pencil with strong coloring property. 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] Aiming at the deficiencies of the prior art, the invention provides an elastic plastic pencil with strong coloring property. [000...
