Abstract
The invention discloses a kind of clean pencil-lead of self raising flour dirt, it is made up of the raw material of following components：45 65 parts of graphite, 10 30 parts of clay, 2 18 parts of animal fat, 5 15 parts of plant virgin rubber, 5 10 parts of sodium thiosulfate, 5 12 parts of developer, 5 20 parts of wax.Animal fat is one or any several any component combination thing in sheep oil, lard, butter.A kind of dust of the clean pencil-lead of self raising flour dirt of the present invention is less, user of service is played a protective role, suitable pupil uses；Meanwhile, the present invention with the addition of modified synthesis wax, add the resistance to elevated temperatures of dispensing.
Description
Technical field
The invention belongs to pencil technical field, and in particular to a kind of clean pencil-lead of self raising flour dirt.
Background technology
Pencil, be for carrying out the main apparatus that art painting is sketched the contours, while be also one of schooling apparatus that student commonly uses,
Pencil is mainly what is be made up of pencil shaft and pencil-lead, and the main component of pencil-lead is all graphite.The pen core of pencil is to use in fact
What graphite and clay were mixed by a certain percentage.Such as the prefix of " h " i.e. English " hard " (hard), clay is represented, is used
To represent the hardness of pencil-lead.Digital bigger (such as 6h) of " h " above, pencil-lead is harder, namely in pen core with graphite
The clay ratios of mixing are bigger, and the word write out substantially, is not commonly used to manifolding." b " is the word of English " black " (black)
Head, represents graphite, to the obvious degree for representing the soft situation of pencil-lead matter He writing.It is most soft with " 6b ", writing is most black,
It is conventional that to paint, common pencil label is then generally " hb ", " 2b " is generally for applying the pencil label of answering card during examination,
But the pencil-lead of existing market is more dried due to it, daily in use, substantial amounts of dust can be produced, although dust sheet
Body toxicity less, if but dust be inhaled by the user in vivo, certain harm is will result in, especially for just going to school not
Pupil just is dangerous bigger.
The content of the invention
In view of the above-mentioned deficiencies in the prior art, it is an object of the present invention to now provide a kind of self raising flour dirt clean pencil-lead.
In order to solve the above technical problems, the technical solution adopted by the present invention is：A kind of clean pencil-lead of self raising flour dirt, it is innovated
Point is：It is made up of the raw material of following components：45-65 parts of graphite, 10-30 parts of clay, 2-18 parts of animal fat, plant
5-15 parts of virgin rubber, 5-10 parts of sodium thiosulfate, 5-12 parts of developer, 5-20 parts of wax.
Further, a kind of clean pencil-lead of self raising flour dirt, is made up of the raw material of following components：50-60 parts of graphite, clay
15-25 parts, 5-15 parts of animal fat, 8-12 parts of plant virgin rubber, 5-8 parts of sodium thiosulfate, 6-10 parts of developer,
8-15 parts of wax.
Further, a kind of clean pencil-lead of self raising flour dirt, is made up of the raw material of following components：55 parts of graphite, clay 20
Part, 10 parts of animal fat, 10 parts of plant virgin rubber, 7 parts of sodium thiosulfate, 8 parts of developer, 12 parts of wax.
Further, described animal fat is one or any several any component in sheep oil, lard, butter
Composition.
Beneficial effects of the present invention are as follows：A kind of dust of the clean pencil-lead of self raising flour dirt of the present invention is less, to user of service
Play a protective role, suitable pupil uses；Meanwhile, the present invention with the addition of modified synthesis wax, add the heat-resisting quantity of dispensing
Energy.
