Dry.
Wherein, a small amount of formaldehyde can play the effect of stabilizer to ink, meanwhile, if adding more than one coloring agent
Words, formaldehyde can make this two or more coloring agent crosslink reaction so as to color is more stable, and plays certain hyperchromic work
With.Formaldehyde amount due to using is less, there is not the free state that human body can be produced with harm in therefore stable ink
Formaldehyde.Likewise, the use of a small amount of methanol can play hyperchromic effect, simultaneously and non-hazardous.Stearic acid, sodium alginate, shallow lake
Powder improves the stability of this ink, it is to avoid situations such as precipitation occurs.The addition of alkylphenol polyoxyethylene, can make this ink have one
Fixed penetrating power, writes on paper dry fast.The addition of BIT, can be to various former in this ink
Material plays certain antisepsises.Glycerol and propylene glycol can make nib when exposed to air, improve its anti-dry time, with
When, other raw materials are also acted as with the effect of hydrotropy.
When this ink uses, it is exposed to the dry resistance energy of in the air for improving nib further, this second component also includes
Sorbitol and ethyl cyclohexane.Simultaneously as more by improving the raw material that added of performance, this second component is also added into β-hydroxyl
Base ethyl urea and diethanolamine, play certain solubilization-aid effect to each raw material.
Second aspect, the invention provides the preparation method of the colored hydrolysis ink of above-mentioned erasable disappearance of fading, including
Following steps：
S11：Sodium hydroxide is dissolved in part distilled water, adds ethanol, stirring obtains alkali liquor；
S12：Add at least one in red stain and blue colorant in alkali liquor, and ultrasonic stirring is carried out to solution
Mix 1h；
S13：Fill into remaining distilled water, be mix homogeneously under 0.092MPa～0.08MPa in vacuum, standing degassing,
It is filtrated to get the colored hydrolysis ink of erasable disappearance of fading.
By stirring under vacuum, can effectively reduce the bubble producing in preparation process, shorten standing degassing
Time, improve yield, thus reducing production cost.
Further, since this colour hydrolysis ink can make multiple color, therefore, can pass through in above-mentioned steps S12
To obtain the ink of required color, this S12 specifically may include S121, S122, S123 or S124 to the coloring agent being added.Wherein
S121：Add red stain in alkali liquor, and ultrasonic agitation 1h is carried out to solution, obtain red ink the most at last.S122:To
Add blue colorant in alkali liquor, and ultrasonic agitation 1h is carried out to solution, obtain blue ink the most at last.S123:To in alkali liquor
Add red stain and blue colorant, and ultrasonic agitation 1h carried out to solution, obtain the most at last purple ink or red-blue-
Chromatic ink between purple.S124：At least one and the yellow colorants in red stain and blue colorant are added in alkali liquor, and
Ultrasonic agitation 1h is carried out to solution, finally can obtain orange, green, black or other chromatic inks.
The third aspect, present invention also offers the preparation of the colored hydrolysis ink of another above-mentioned erasable disappearance of fading
Method, comprises the steps：
S21：Prepare each raw material by default proportioning, and distilled water is divided into three parts, ethanol is divided into two parts, in order to incite somebody to action
The various variety classeses and different raw material of dissolving situation dissolves respectively, wherein, the tripartite ratio of distilled water is 3:(2～
3):(3～5), it is 1 that ethanol is divided into two-part ratio:(2～3), concentration of alcohol is 95%.
S22：Sodium hydroxide is dissolved in Part I ethanol, and adds Part I distilled water, mix homogeneously obtains alkali
Liquid.
S23：Add at least one in red stain and blue colorant in S22 resulting solution, and solution is entered
Row ultrasonic agitation 1h.Because this colour hydrolysis ink can make multiple color, therefore, in this step, can be by being added
Plus the ink to obtain required color for the coloring agent, this S23 specifically may include S231, S232, S233 or S234.Wherein, S,
231：Add red stain in alkali liquor, and ultrasonic agitation 1h is carried out to solution, obtain red ink the most at last.S232:To
Add blue colorant in alkali liquor, and ultrasonic agitation 1h is carried out to solution, obtain blue ink the most at last.S233:To in alkali liquor
Add red stain and blue colorant, and ultrasonic agitation 1h carried out to solution, obtain the most at last purple ink or red-blue-
Chromatic ink between purple.S234：At least one and the yellow colorants in red stain and blue colorant are added in alkali liquor, and
Ultrasonic agitation 1h is carried out to solution, finally can obtain orange, green, black or other chromatic inks.
S24：Add formaldehyde in S23 resulting solution, and stir 2h at 40-60 DEG C.A small amount of formaldehyde can be to ink
Play the effect of stabilizer, meanwhile, if in S23 step, if adding more than one coloring agent, formaldehyde can make this two kinds with
On coloring agent crosslink reaction so as to color is more stable, and play certain hyperchromic effect.Due to the formaldehyde amount using
Less, there is not the formaldehyde of the free state that human body can be produced with harm in therefore stable ink.But due to formaldehyde tool
There is certain toxicity, therefore this step needs in confined conditions.
S25：Starch is positioned in Part II distilled water, so that starch is completely dissolved, because starch is higher in temperature
In the case of be dissolved in water after will become bulk it is difficult to be completely dissolved, therefore, at normal temperatures it need to be stirred with 20min, then again plus
Enter sodium alginate, glycerol, propylene glycol, temperature be 40-60 DEG C, vacuum be 0.092MPa～0.08MPa under conditions of ultrasonic
Stirring 6h, temperature raises and quickly dissolves beneficial to each raw material, meanwhile, is stirred effectively reducing preparing under vacuum condition
The bubble producing in journey, shortening the time of later stage standing degassing, improving yield, thus reducing production cost.In this step, each former
The addition of material, will increase denseness and the stability of ink, meanwhile, glycerol, propylene glycol play the effect of hydrotropy to sodium alginate.
S26：S25 gained mixed liquor is added in S24 gained mixed liquor with the speed of 50ml/min, stirs while adding,
Until mix homogeneously.
S27：Part II ethanol is dissolved in obtain ethanol solution in Part III distilled water, then by methanol, Hard Fat
Acid, BIT, alkylphenol polyoxyethylene and essence dissolve in ethanol solution, and are 50-70 in temperature
DEG C, vacuum be 0.092MPa～0.08MPa under conditions of ultrasonic agitation 8h.Or Part II ethanol is dissolved in Part III steaming
