Description
Technical field
The present invention relates to the pencil-leads and pencil of pencil preparation field more particularly to a kind of clear writing, written cleaning.
Background technique
Pencil is teaching, indispensable tool in drawing course, it has the characteristics that easily to wipe, easily modification, in primary school
It is had a decisive role in raw study and people's Plot Work.Pencil is mainly to be made of pencil shaft and pencil-lead, lead
The main component of pen core is all graphite.Graphite is a kind of Dark grey, matter is soft and has the minerals of soapy feeling.
Graphite is easy to fall off, and the surface of friction pen core or writing notes slightly is easy for being contacted and falls off and seem fuzzy, stone
Ink is also often adhered to the other parts in addition to person's handwriting, so that entirely writing plate face becomes unintelligible, untidy, it is especially small
Child is when operation is write, it is easier to thus fuzzy notes or by graphite be sticked to and make body or clothes dirty.
Summary of the invention
Technical problems based on background technology, the invention proposes a kind of clear writings, the pencil-lead of written cleaning
And pencil.
The present invention provides a kind of clear writing, the pencil-lead of written cleaning, raw material includes: graphite 60- by weight
70 parts, 5-10 parts of talcum powder, 5-10 parts of white mica powder, 5-10 parts of modified grease, 3-8 parts of beeswax, 3-8 parts of acrylic emulsion.
Preferably, pencil-lead is prepared with the following method:
S1, various raw materials are weighed according to the proportion, it is spare；
S2, graphite, talcum powder, white mica powder are mixed, obtains mixed-powder；
S3, modified grease, beeswax, acrylic emulsion are heated to 60-80 DEG C, are uniformly mixed, obtain mixed solution；
S4, mixed solution obtained in S3 is added in mixed-powder obtained in S2, after mixing evenly, mediates 15-20 points
Clock, obtains pencil-lead mixing by 90-100 DEG C of kneading temperature；
S5, by pencil-lead mixing extrusion forming obtained in S4, be dried to obtain pencil-lead.
Preferably, in pencil-lead preparation method S5, dry temperature is 45-50 DEG C, drying time 8-10 hour.
Preferably, modified grease is prepared using following methods: 20-30 parts by weight animal fat being heated to 70-85 DEG C, is added
Enter the sodium hydroxide solution of 5-10 parts by weight, 15%-20% weight ratio, after insulated and stirred 5-10 minutes first time, 1-2 weight is added
Part, the sodium alginate soln of 1%-3% weight ratio and 4-8 parts by weight diethanol amine, second insulated and stirred 50-60 minutes, separation
Water phase is removed, modified grease is obtained.
Preferably, with ultrasonication, ultrasonic frequency 20-25kHz while second of insulated and stirred.
Preferably, animal fat is butter or sheep oil.
The present invention also provides a kind of pencil, including pencil-lead and pencil shaft, the pencil-lead is above-mentioned clear writing, book
Face cleaning pencil-lead.
Clear writing provided by the invention, the pencil-lead of written cleaning and pencil color are dense, fluent writing, and pencil-lead is viscous
Consistency is high, and in slightly friction written handwriting, graphite is not easily to fall off, and writing will not obscure, and writing surface keeps clear, clean and tidy,
It is not easy to make hand and clothing dirty.
Pencil-lead provided by the invention is using graphite as color developing agent, and talcum powder has dispersibility well, and satiny degree is big, so that
Fluent writing；White mica powder is added, increases the hardness of pencil-lead, improves that pencil-lead is resistance to fall performance；Beeswax, acrylic emulsion are viscous
Agent is tied, is acted synergistically with modified grease, under the premise of not influencing normally to write, improves the viscosity of pencil-lead, is avoided light
When micro tribology pencil-lead or written handwriting, graphite falls off.
The preferred preparation method of modified grease of the present invention, improves the ductility, viscosity and antioxygenic property of grease.
