Description
Technical field
The present invention relates to drawing pigment additive agent field, more particularly to a kind of peach colloidal solution and preparation method thereof.
Background technology
Peach gum is the colloid vitrina that the rosaceous plants such as peach or mountain peach trunk is secreted out of by machinery wound or after causing a disease.
It is air-dried on trunk or use other dewaterings and the solid matter that is formed is former peach gum, former peach gum is pink or faint yellow
Translucent solid block, smooth in appearance can only generally soak and rise, it is not easy to be completely dissolved, aqueous solution is tacky, belongs to polysaccharide object
Matter.Former peach gum obtains commodity solid peach gum after the processing such as removal impurity, hydrolysis or modification, drying.
The lysigenous peach colloidal solution of solid peach gum can be used in drawing pigment, can improve the colour retention and bonding of pigment
Property.But since peach colloidal solution has color more, color is more than No. 10 colorimeters, therefore has seriously affected the colour rendering of drawing pigment
Energy.And peach gum fluid solid content is less than 20%, reduces the caking property of drawing pigment.
Invention content

Specific implementation mode
For a further understanding of the present invention, the preferred embodiment of the invention is described with reference to embodiment, still
It should be appreciated that these descriptions are only the feature and advantage further illustrated the present invention, rather than to the claims in the present invention
Limitation.
Embodiment of the invention discloses that a kind of preparation method of peach colloidal solution, includes the following steps, referring specifically to Fig. 1：
Step (A)：Solid peach gum after crushing is soaked in water, and pH value is adjusted to 9~10 using triethanolamine；
Step (B)：Addition hydrogenperoxide steam generator is 6~7 up to pH value, is then heated up, until solid peach gum is completely dissolved,
Obtain the first treatment fluid；
Step (C)：Calcium hydroxide is added in first treatment fluid, obtains second processing liquid；
Step (D)：The pH value of the second processing liquid is adjusted to 9~10, hydrogenperoxide steam generator is added and is stirred,
Then by precipitating and removing impurity, peach colloidal solution is obtained.
In the present invention, by controlling the condition of condition and bleaching that solid peach gum dissolves in water, solid content is obtained
Peach colloidal solution high, coloration is low.
According to the present invention, step (A)：Solid peach gum after crushing is soaked in water, and pH value is adjusted to 9 using triethanolamine
~10.
In the step (A), using the solid peach gum after crushing, the solid peach gum after the crushing is preferably less than 5
Centimetre bulk, in order to its water swelling.
Solid peach gum after crushing is soaked in water, by water swelling, is dispersed into smaller particle.The soaking time
Preferably 50~60 minutes, soaking temperature was preferably 60~70 DEG C.The mass ratio of the solid peach gum and water is preferably 1:1.5~
2。
After solid peach gum is dispersed into smaller particle, pH value is adjusted to 9~10 using triethanolamine.The triethanolamine
Make solution alkaline, protect the peach gum polysaccharide molecule of macromolecule, avoids peach gum polysaccharide molecule excessive during sequential hydrolysis
Fracture.
Preferably, further include stirring 30~40 minutes, to ensure three second after using triethanolamine adjusting pH value to 9~10
Around the evenly dispersed solid peach gum particle of hydramine.
Step (B)：Addition hydrogenperoxide steam generator is 6~7 up to pH value, is then heated up, until solid peach gum is completely dissolved,
Obtain the first treatment fluid.
In the step (B), since hydrogen peroxide has oxidisability, and there is extremely weak acidity, therefore utilized
Hydrogen peroxide solution promotes the dissolving of solid peach gum；Meanwhile the part peach gum polysaccharide in solid peach gum is in the work of hydrogenperoxide steam generator
With lower hydrolytic cleavage, it is converted to the smaller peach gum polysaccharide of molecular weight, and be dissolved in the water.The smaller peach gum polysaccharide of molecular weight is got over
More, the viscosity of solution is lower, and viscosity is too low will to influence its final solid content, it is therefore desirable to the viscosity of suitable control solution.Institute
The mass percentage concentration for stating hydrogenperoxide steam generator is preferably 20~30%.
It is stirring while adding during hydrogenperoxide steam generator is added, until pH value is 6~7, more preferably 6.5.Opposite
In neutral environment, hydrogenperoxide steam generator had both promoted the dissolving and hydrolysis of solid peach gum particle, and avoided peach gum point
The excessive fracture of son.
If the solid peach gum dissolving is too fast, solution ph is less than 6, then preferably adjusts pH value extremely by adding triethanolamine
6~7；If the solid peach gum dissolved slowly, solution ph is higher than 10, then preferably adjusts pH value by adding hydrogenperoxide steam generator
It adjusts to 6~7.
After adjusting pH value, then heat up, it is preferable that it is described to be warming up to 75~80 DEG C, and the temperature is maintained until solid peach
Glue is completely dissolved.Temperature is maintained 80 DEG C or less and being completely dissolved for solid peach gum can be completed by the present invention, is less than the prior art
In peach gum dissolving solution temperature, and solute effect is preferable.
The first treatment fluid obtained, viscosity is preferably 3000~3200CPS.
Step (C)：Calcium hydroxide is added in first treatment fluid, obtains second processing liquid.
The effect of the calcium hydroxide is combined with the impurity in solid peach gum, and in the form of being formed and be precipitated, amount impurity is gone
It removes.The additive amount of the calcium hydroxide is preferably the 0.2~0.3% of solid peach gum quality.The second processing liquid of acquisition can be used for
Bleaching.
Step (D)：The pH value of the second processing liquid is adjusted to 9~10 under 65~75 DEG C of temperature condition, is added
Hydrogenperoxide steam generator is simultaneously stirred, and then by precipitating and removing impurity, obtains peach colloidal solution.
In the step (D), first the pH value of second processing liquid is adjusted to 9~10, it is preferable that by the way that three ethyl alcohol are added
Amine adjusts the pH value of second processing liquid to 9~10；
Then the oxidisability for utilizing hydrogenperoxide steam generator, makes pigment by oxidation decoloration.Preferably, hydrogenperoxide steam generator is added
After, pH value gradually will be down to 7~8, close to neutrality by 9~10.
In this step, the second processing liquid reuses the side of hydrogen peroxide bleaching by way of first promoting pH value
Formula protects the peach gum polysaccharide molecule of macromolecule therein, maintains the solid content of peach colloidal solution.
In order to fully carry out blanching effect, the mixing time is preferably 20~30 minutes.Then, it goes to clean by precipitation
Matter obtains peach colloidal solution.The time of the precipitation is preferably greater than 20 hours, more preferably 20~30 hours.
