Description
Technical field
The present invention relates to pencil preparation fields more particularly to a kind of no wax colored pencil lead and preparation method thereof.
Background technique
Colored pencil lead is to use colorant as a kind of pencil-lead of colorant, by pursuing for student and designer group.
Color pencil lead is mainly using clay as binder, and additive color material, pigment, constitution raw material, water, adhesive, grease and wax etc. are through mixed
Conjunction is ground into the techniques such as sheet stock, stirring, extrusion forming, drying, commonly known as clay color core.
Adhesive selected by traditional colored pencil pen core be generally adragant, Arabic gum, peach gum, cellulose,
Water-soluble dextrine powder etc., and the grease and wax of more amount is added, therefore in subsequent stoving process, temperature cannot be arranged too
Height can only control between 40 DEG C -45 DEG C, need to dry 3-4 days, the moisture in colored pen core could be dried to technique to be reached
Requirement.Moreover, because contain wax material in composition, thus its written trace is not easy to wipe.
Summary of the invention
Technical problems based on background technology, the invention proposes a kind of no wax colored pencil lead and its preparation sides
Method.
The present invention provides a kind of no wax colored pencil lead, raw material includes: 45-55 parts of bentonite, talcum by weight
15-20 parts of powder, 10-20 parts of white mica powder, 10-15 parts of inorganic pigment powder, 10-15 parts of polyethylene glycol (PEG-300), glycerol 3-7
Part, 10-15 parts of water.
Preferably, the raw material of no wax colored pencil lead further includes 0.5-1.5 parts of magnesium chloride.
Preparation method the present invention also provides this kind without wax colored pencil lead, comprising the following steps:
S1, various raw materials are weighed according to the proportion, it is spare；
S2, solid material is mixed, is ground to 2000-3000 mesh, obtains mixed-powder；
S3, polyethylene glycol (PEG-300) and water are mixed, obtains mixed solution；
S4, mixed solution obtained in S3 is added in mixed-powder obtained in S2, after mixing evenly, mediates 15-30 points
Clock after glycerol is added, continues to mediate 30-50 minutes, 90-150 DEG C of kneading temperature, obtains pencil-lead mixing；
S5, by pencil-lead mixing extrusion forming obtained in S4, be dried to obtain no wax colored pencil lead.
Preferably, in S4 glycerol divide 2-3 times addition, the glycerin weight being added every time is equal, it is adjacent twice be added glycerol it
Between, it mediates 5-8 minutes.
Preferably, temperature dry in S5 is 130-150 DEG C, drying time 50-70 minute.
Preferably, kneading temperature is 110-130 DEG C in S4.
No wax colored pencil lead provided by the invention is added white mica powder and is increased the strong of pencil-lead with inorganic pigment coloring
Degree, is not easily broken pencil-lead；Polyethylene glycol (PEG-300), glycerol have dispersibility, lubricity, caking property effect, can make
Various raw materials are combined closely, and obtained pencil-lead is homogeneous, fluent writing.The present invention preferably adds in no wax colored pencil lead
Add magnesium chloride, addition magnesium chloride can make the color of colored pencil lead more gorgeous.
No wax colored pencil lead provided by the invention does not contain grease and wax material, can be using higher dry temperature
Degree, substantially reduces the time of drying process.This can be wiped without wax colored pencil lead fluent writing, beautiful in colour with rubber
Completely, it will not leave behind the cured print of white.
