Description
Technical field
The present invention relates to pencil manufacturing technology fields, more specifically, it relates to which high-quality is sustained odor type color pencil lead.
Background technique
Pencil be it is a kind of be used to write and drawing sketch special pens class, be traditional and widely applied articles for daily use.
So-called lead for retractable pencil is the core of pencil, with the variation of time, season, temperature, humidity, can all influence lead for retractable pencil quality.Colored pencil
It is the pencil of color pencil lead, selects the advanced particulate pigment with high absorption colour rendering to be made, color is varied, is good at showing
The fine and smooth texture of object, have transparency and colorfulness, on all types of paper use when can uniform coloring, smoothness describe,
It is important draw tool.
Disclosed in the Chinese invention patent of Publication No. CN105153815A a kind of nontoxic fragrant pencil-lead and
Preparation method, including following raw material are made: 60~80 parts of magnesium silicate, 20~30 parts of clay, 6~10 parts of animal fat, plant
6~10 parts of virgin rubber, 8~12 parts of color developing agent, 3~5 parts of Ground Cloves, 6~8 parts of wrinkled giant hyssop extracting solution, 10~14 parts of peppermint cerebrol, gold and silver
3~5 parts of pollen.
In above-mentioned patent, make obtained pencil-lead that there is certain fragrance by the way that Ground Cloves and honeysuckle powder is added,
But the particle of Ground Cloves and honeysuckle powder is larger and not of uniform size, can not be uniformly dispersed in pencil-lead, lead to pencil
The fragrance that pen core is distributed in use is uneven, it is, therefore, desirable to provide a kind of new scheme solves the above problems.
Summary of the invention
For causing pencil-lead using because pollen particles cannot be uniformly dispersed in pencil-lead in the prior art
The non-uniform problem of the fragrance distributed in the process, the purpose of the present invention one are to provide high-quality sustained release odor type color pencil lead, lead to
It crosses and high-quality sustained release essence is added in pencil-lead, to solve the above technical problems, high-quality prepared by the present invention is sustained fragrant

The quality and quality of odor type color pencil lead entirety, making it, lasting is lasting in actual use.
The purpose of the present invention two is to provide the preparation process of high-quality sustained release odor type color pencil lead, be prepared using this method
High-quality be sustained odor type color pencil lead, the fragrance distributed is uniform and stable, and lasting is more lasting.
To achieve the above object two, the present invention provides the following technical scheme that
The preparation process of high-quality sustained release odor type color pencil lead, comprising the following steps:
High-quality sustained release essence, reinforcing agent and the dispersing agent of corresponding weight percent are adequately mixed evenly step 1,
Obtain mixed liquor；
Step 2 grinds the magnesium silicate of corresponding weight percent and clay, is stirred mixing, is mixed
Object；
Step 3 obtains mixed powder by said mixture with being sieved；
Above-mentioned mixed powder and mixed liquor are mixed evenly step 4, and pigment and pencil-lead lubricant one are added simultaneously
With being mixed, core material is obtained；
Above-mentioned core material is pressed, and is dried by step 5, and high-quality sustained release odor type color pencil lead can be obtained.
By using above-mentioned technical proposal, be conducive to mix high-quality sustained release essence uniformly with each component, and will mix
It closes object to be sieved, is conducive to remove some biggish particles in magnesium silicate and clay, the presence because of larger particles is avoided to cause
High-quality sustained release essence is unevenly distributed.Meanwhile the particle size distribution of magnesium silicate and clay is relatively uniform, and itself and high-quality
The granular size for being sustained essence is close to each other, is conducive to be uniformly dispersed in high-quality sustained release essence in magnesium silicate and clay,
The total quality for improving high-quality sustained release odor type color pencil lead, distributes it uniform and stable, and lasting is more lasting.Together
When, this processing step facilitates operation, and better effect in practice, has good applicability.
Further preferably, following preparation step is specifically included:
Step 1 by high-quality sustained release essence, reinforcing agent and the dispersing agent of corresponding weight percent, and presses (2~3%): (1.5
~3.8%): the ratio of (0.5~1.2%) is adequately mixed evenly, and mixing time is 10~15min, and mixing speed is
500~800rpm temperature is 20~30 DEG C, obtains mixed liquor；
Step 2, by the magnesium silicate of corresponding weight percent and clay in (60~70%): the ratio of (15~25%) is ground
It is milled broken, mixing is stirred in agitator tank, mixing time is 20~30min, and mixing speed is 300~400rpm, is obtained
Mixture；
Said mixture is sieved with the sieve of 1100~1300 mesh, obtains mixed powder by step 3；
Above-mentioned mixed powder and mixed liquor are mixed evenly step 4, and in (4~6%): the ratio of (3~5%) is simultaneously
Pigment is added and pencil-lead lubricant is mixed together, mixing time is 1~3h, and mixing speed is 1800~2500rpm, temperature
