[0060] Preferably, the thickener is an inorganic thickener and / or cellulose ether. For example, it can be fumed white carbon black, sodi...

Embodiment 2

[0068] Embodiment 2 of the present invention provides a method for making ink, see figure 1 shown, including steps:

[0069] Step S110: Dissolving 30%-40% phenolphthalein in 5%-10% edible alcohol and stirring for 10-30 minutes.

[0070] Wherein the specific mass ratio of phenolphthalein and edible alcohol can be adjusted according to actual needs by those skilled in the art, and should be continuously stirred as much as possible during stirring, so that each solution component is fully mixed and dissolved, and the stirring time can also be adjusted by those skilled in the art according to actual needs The specific adjustment is not limited in the present invention.

[0071] Step S111: Add 14%-20% white oil, 12%-15% glycerin and 10%-20% water, and stir for another 1-2 hours.

[0072] The specific mass ratio of white oil, glycerin and water and the stirring time can also be adjusted by those skilled in the art according to actual needs, and the present invention does not enume...

Embodiment 3

[0077] Embodiment 3 of the present invention also provides a method for making ink, comprising the steps of:

[0078] Step S210: Dissolve 40% phenolphthalein in 5% edible alcohol, and stir for 20 minutes with a disperser.

[0079] Step S211: Add 14% white oil, 12% glycerin and 10% water, then disperse and stir for 1 hour.

[0080] Step S212: Add 8% silicon dioxide, and carry out dispersing and stirring for 30 minutes.

[0081] Step S213: Add 10% thickener, disperse and stir for 10 minutes, then add 1% sodium hydroxide and continue stirring.

[0082] In general, first dissolve 40% phenolphthalein by weight in 5% edible alcohol, stir continuously for 20 minutes with a disperser, add 14% white oil, 12% glycerin, and 10% water, and then disperse and stir for 1 hour , then add 8% silicon dioxide, then disperse and stir for 30 minutes, then add 10% thickener, then disperse and stir for 10 minutes, then add 1% sodium hydroxide and stir. In this way, qualified ink products are prod...

Abstract

The invention provides ink, which comprises the following components in weight percent: 30-40% of phenolphthalein, 8-15% of thickening agent, 14-20% of white oil, 12-15% of glycerin, 10-20% of water, 8-10% of silicon dioxide, 5-10% of edible alcohol, and 0.5-1.5% of sodium hydroxide. The invention further provides a preparation method for the ink. The method is realized through the following steps (in weight percent): dissolving the 30-40% of phenolphthalein in the 5-10% of edible alcohol, and stirring for 10-30 minutes; adding the 14-20% of white oil, the 12-15% of glycerin and the 10-20% of water, and stirring again for 1-2 hours; adding the 8-10% of silicon dioxide, and stirring for 20-40 minutes; and moreover, adding the 8-15% of thickening agent, stirring for 5-15 minutes, adding the 1% sodium hydroxide and stirring again. The ink and the preparation method have the advantages that the ink is suitable for writing on the blackboard, prevents dust from flying about, and is easy to wipe.

Description

technical field [0001] The invention relates to the technical field of office supplies, in particular to an ink and a manufacturing method thereof. Background technique [0002] Ink appears with the correction of writing instruments, such as the use of fountain pens. From the chemical properties of its raw materials, it can be divided into blue-black ink and color ink. [0003] Blue black ink, also known as tannin iron ink, is composed of blackening and lasting ingredients, pigment ingredients, stabilizers, resists, wetting agents and preservatives. [0004] The long-lasting blackening ingredients are mainly tannic acid (C 4 h 10 o 9 ), gallic acid (C 7 h 6 o 5 ·H 2 O) and ferrous sulfate (FeSO 4 ) and other components are combined with each other to form ferrous tannate and ferrous gallate, which will become insoluble high-valent iron after oxidation, namely iron tannate and ferric gallate. The former enhances water resistance, and the latter enhances blackening. T...
