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
The present invention relates to a kind of pencil, particularly a kind of polychrome painting pencil.
Background technology
General pencil adopts wood pen holder, and its material consumption timber is large, is unfavorable for environmental protection.Wood pencil processing and manufacturing process is more complicated, pollutes greatly, and cost is high, quality control difficulty, and the less variation of outward appearance, pen core is toxic, is easy to fracture.In order to overcome the shortcoming of Wood pencil, had now plastic pencil, but the batching of its penholder and pen core is also unreasonable, elasticity is poor, and children easily broke when using or playing, and pen core is write difficultly, and coloring is poor, and the cost of product is higher.
Summary of the invention
The object of the invention is the defect for prior art, provides for the deficiencies in the prior art, a kind of polychrome painting pencil, convenient drawing shades of colour.
The present invention is achieved through the following technical solutions, develop a kind of polychrome painting pencil, comprise penholder and pen core, it is characterized by: pen core is tough matter pen core, substantially the one-tenth of counting ratio by following weight is grouped into, graphite powder 50-60, polystyrene (PS) 20-30, haloflex (CPE) 3 calcium stearate 3-5, substantially count ratio by following weight one-tenth be grouped into, thermoplastic elastomer (TPE) (JEP) 30-40, polystyrene (PS) 9, talcum powder 80, filler 3.5, crosslinking agent 0.6.
The surface of described penholder is provided with epidermal area, the thermoplastic elastomer (TPE) (JEP) that is mainly 4:6 by weight ratio.
Advantage of the present invention: penholder elasticity very good, bending also there will not be fracture, falls on ground and also can rebound, pen core is tough matter, also easy fracture not, fluent writing, coloring is very strong.
Specific embodiment:
Example 1:
A kind of polychrome painting pencil, pen core is tough matter pen core, substantially the one-tenth of counting ratio by following weight is grouped into, graphite powder 50, polystyrene (PS) 20, haloflex (CPE) 3,, calcium stearate 3, substantially count ratio by following weight one-tenth be grouped into, thermoplastic elastomer (TPE) (JEP) 30, polystyrene (PS) 9, talcum powder 80, filler 3.5, crosslinking agent 0.6.The surface of described penholder is provided with epidermal area, the thermoplastic elastomer (TPE) (JEP) that is mainly 4:6 by weight ratio.Also can add some auxiliary agents, as titanium dioxide, improve stability, can add in addition industrial toner, as Lithol Red, can make surface color colorful attractive in appearance.
Example 2:
A kind of polychrome painting pencil, pen core is tough matter pen core, substantially the one-tenth of counting ratio by following weight is grouped into, graphite powder 50, polystyrene (PS) 30, haloflex (CPE) 3,, calcium stearate 3, substantially count ratio by following weight one-tenth be grouped into, thermoplastic elastomer (TPE) (JEP) 30, polystyrene (PS) 8, talcum powder 80, filler 3.6, crosslinking agent 0.6.The surface of described penholder is provided with epidermal area, the thermoplastic elastomer (TPE) (JEP) that is mainly 4:6 by weight ratio.Also can add some auxiliary agents, as titanium dioxide, improve stability, can add in addition industrial toner, as Lithol Red, can make surface color colorful attractive in appearance.
Claims (2)
1. a polychrome painting pencil, comprise penholder and pen core, it is characterized by: pen core is tough matter pen core, substantially the one-tenth of counting ratio by following weight is grouped into, graphite powder 50-60, polystyrene (PS) 20-30, haloflex (CPE) 3 calcium stearate 3-5, substantially count ratio by following weight one-tenth be grouped into, thermoplastic elastomer (TPE) (JEP) 30-40, polystyrene (PS) 9, talcum powder 80, filler 3.5, crosslinking agent 0.6.
