The oleophilic white pigment is aluminum oxide coated metal oxide pigment and/or organic coated metal oxide pigment, and the metal oxide is at least one selected from titanium dioxide, zinc oxide and zirconium oxide.
By subjecting the white pigment to the coating treatment, a white pigment stably dispersed in the dyne liquid oily solvent and the dyne liquid aqueous solvent can be obtained.

dispersing rutile type titanium dioxide in deionized water, adding sodium hexametaphosphate, and preparing into a titanium dioxide aqueous solution with the mass concentration of 150-250 g/L; regulating the pH value to 8.5-9, and heating to 80-85 ℃; and (3) dropwise adding a sodium silicate solution with the concentration of 0.3-0.4mol/L into the titanium dioxide aqueous solution, simultaneously dropwise adding a sulfuric acid solution with the concentration of 0.1-0.2mol/L, keeping the pH below 10, curing the slurry at 80-85 ℃ for 1-2 hours after the dropwise adding, washing with deionized water, and performing heat treatment at 170-180 ℃ for 8-10 hours to obtain the silicon-coated titanium dioxide pigment.
Illustratively, the aluminum coated titanium dioxide pigment may be obtained by the following preparation method:

It is within the scope of the present invention that only one of the above ways to obtain silicon-coated titanium dioxide pigments and aluminum-coated titanium dioxide pigments may be obtained by other means.
In an embodiment of the present invention, the aqueous solvent of the dyne liquid is selected from at least one of water, N-methylpyrrolidone, N-ethylpyrrolidone, diethylene glycol, triethylene glycol, tetraethylene glycol, glycerol, isopentyl glycol, ethylene glycol, 1, 2-pentanediol, 1, 2-propanediol, butanediol, 2-methyl-1, 3-propanediol, 1, 2-hexanediol, benzyl alcohol, polyethylene glycol 200, dipropylene glycol, 1, 3-propanediol, sodium pyrrolidone carboxylate, 2-methyl-2, 4-pentanediol, formamide, triethanolamine, diethylene glycol diethyl ether, diethylene glycol butyl ether, diethylene glycol monoethyl ether, propylene glycol monomethyl ether, propylene glycol methyl ether, dipropylene glycol monomethyl ether, ethylene glycol diethyl ether or phenoxyethanol.
The aqueous solvent of the dyne solution contains at least one of water, N-methyl pyrrolidone and N-ethyl pyrrolidone.
Optionally, the aqueous solvent of the dyne liquid contains at least one of N-methyl pyrrolidone or N-ethyl pyrrolidone, and at least one of 1, 2-propylene glycol carbonate, ethyl lactate, ethylene glycol diacetate, 2-phenethyl alcohol, propylene glycol diacetate, dimethyl oxalate or dodecanol carbonate is added to the aqueous solvent of the dyne liquid. The solvents have better compatibility with N-methyl pyrrolidone or N-ethyl pyrrolidone.
Diethylene glycol diethyl ether, diethylene glycol butyl ether, diethylene glycol monoethyl ether, propylene glycol monomethyl ether, propylene glycol methyl ether, dipropylene glycol monomethyl ether, ethylene glycol diethyl ether, phenoxyethanol, 1, 2-propylene glycol carbonate, ethyl lactate, ethylene glycol diacetate, 2-phenethyl alcohol, propylene glycol diacetate, dimethyl oxalate or dodecanol carbonate have less affinity for hydrophilic titanium dioxide than other listed aqueous solvents.
N-methylpyrrolidone or N-ethylpyrrolidone has a super affinity for hydrophilic titanium dioxide, next to the affinity of water for hydrophilic titanium dioxide. At the same time, N-methylpyrrolidone has a higher affinity for esters and ethers than water, so that when hydrophilic titanium dioxide is mixed into esters and ethers, N-methylpyrrolidone is used as a linking agent, and the dissolution and suspension effects are completely different before and after mixing. In conclusion, N-methyl pyrrolidone or N-ethyl pyrrolidone can be coupled with hydrophilic titanium dioxide and certain solvents such as ether esters and the like with poor affinity for the hydrophilic titanium dioxide. After N-methyl pyrrolidone or N-ethyl pyrrolidone is added, the obtained dissolution effect is very good, and the effect similar to that of water in the mixed solution of hydrophilic alcohols and hydrophilic titanium dioxide is achieved.
In a preferred embodiment of the invention, the aqueous solvent of the dyne solution contains at least 1,2 pentanediol. In the prior art, the solvent is formed by mixing MPD and diethylene glycol, and although the diethylene glycol is a hydrophilic raw material and can be mixed with hydrophilic titanium dioxide, the MPD has poor affinity to both hydrophilic titanium dioxide and lipophilic titanium dioxide. Therefore, the invention adopts 1,2 pentanediol as the aqueous solvent of the dyne liquid. The 1,2 pentanediol has very good hydrophilicity, and after being mixed with the hydrophilic titanium dioxide, the suspending property of the hydrophilic titanium dioxide is very good, and the suspending state is maintained for a long time, so that the actual use requirement can be completely met. The content of water in the dyne aqueous solvent is the equilibrium water content of the dyne aqueous solvent at 23 ℃ and 50% RH. For example, the content of water in 1,2 pentanediol is the equilibrium water content of 1,2 pentanediol at 23℃and 50% RH. In this case, 1,2 pentanediol is advantageous in that it does not absorb moisture or evaporate moisture, and thus the stability of the dyne solution is improved. The performance change caused by the water content change is avoided.
In the embodiment of the invention, the white dyne solution further comprises a moisturizing component, and the moisturizing component at least comprises sodium pyrrolidone carboxylate. Because most of the water-based raw materials of the dyne liquid are water-absorbing substances, in the dyne liquid which needs to prepare a large amount of water, the water volatilizes at an undetermined volatilization rate in the use process due to the fact that the water is adsorbed by different water-based raw materials, and finally, the ratio of the dyne liquid is changed, so that the final dyne value is changed, and the use precision is affected. By comparison, the volatilization speed of the moisture in the aqueous solution of the moisturizing component sodium pyrrolidone carboxylate and the aqueous solution of the other water-based raw materials with the same proportion can be found that the volatilization speed of the moisture in the aqueous solution of the sodium pyrrolidone carboxylate is far lower than that of the aqueous solution of the other water-based raw materials with the same proportion. According to the situation, the existing product requires to tightly close the pen cap under the condition of not using the dyne pen, and the pen cap is tightly closed in time after being used, so that the shelf life is generally 6 months after being unsealed under the use requirement. For this situation, the present invention introduces a moisturizing ingredient: sodium pyrrolidone carboxylate (PCA-Na) can increase the stability of the system by about several times, typically three times, at normal temperature and humidity compared to other hygroscopic materials.
In an embodiment of the present invention, the total content of at least one of water, N-methylpyrrolidone or N-ethylpyrrolidone in the aqueous solvent of the dyne liquid is 3% to 99% by mass of the aqueous solvent of the dyne liquid, and more preferably 40%.
In the embodiment of the invention, the dyne liquid oily solvent is selected from any one or a mixture of more than one of ethanol, benzyl alcohol, 1,2,4 butanetriol, 1, 2-propylene carbonate, ethyl acetate, n-hexanol, isoamyl propionate, butyl butyrate, dimethyl oxalate, ethyl caproate, dodecyl carbonate, ethyl lactate, isoamyl butyrate, ethylene glycol diacetate and propylene glycol diethyl ester.
In the embodiment of the invention, the mass of the hydrophilic white pigment accounts for 1-10% of the mass of the aqueous solvent of the dyne liquid. Specifically, the above ratios are 3%, 5%, 8% and 10%, respectively.
In the embodiment of the invention, the mass of the lipophilic white pigment accounts for 1-10% of the mass of the dyne liquid oily solvent. Specifically, the above ratios are 3%, 5%, 8% and 10%, respectively.
For a further understanding of the present invention, preferred embodiments of the invention are described below in conjunction with the examples, but it should be understood that these descriptions are merely intended to illustrate further features and advantages of the invention, and are not limiting of the claims of the invention.
Table 1 shows the aqueous solution of dyne used in each example of the present invention and the ratio of water added to the aqueous solution of dyne, and further hydrophilic titanium dioxide was added to the aqueous solution of dyne. After the preparation is finished, the pigment (hydrophilic titanium dioxide) can slowly precipitate, the upper layer solution can not slowly become clear more and more because of the subsidence of the pigment, the solubility of the solution to the hydrophilic titanium dioxide is judged by observing the precipitation condition of the bottom layer solution, and the higher the precipitation height is, the faster the pigment precipitates in the solution, and the weaker the solubility of the solution to the pigment is.
TABLE 1
As is clear from Table 1, the examples in which 1,3 propylene glycol+25% water, 1,2 propylene glycol+25% water and triethylene glycol+25% water were used as solvents gave the best results in suspending pigments in the dyne liquid, and the pigments could be left to stand for a long period of time while keeping the pigments suspended, and the use was satisfied.
In addition, the present invention can achieve variation in the dyne value by blending between solvents, see tables 2-4. Wherein examples 21-24 employed 1,2 pentanediol and ethanol + hydrophilic titanium dioxide. Examples 25-30 employed 1,2 pentanediol and diethylene glycol + hydrophilic titanium dioxide. Examples 31-34 employed ethanol and 1, 2-propanediol carbonate + hydrophilic/lipophilic white pigment.
TABLE 2
TABLE 3 Table 3
TABLE 4 Table 4
The comparative dissolution suspension effect of MPD on hydrophilic titanium dioxide with 1,2 pentanediol is provided in the examples of table 5. Wherein, the bottom of the test tube used for testing has an outer diameter of about 15mm and a wall thickness of 1mm, is a semicircle with an inner diameter of 13mm, and has a radius of 6.5, and all the sediment depths are subtracted by 1mm after the wall thickness depth of the strip is tested. The deposition volumes of 6.1mm,1.7mm and 0.5mm can be calculated according to the heights, namely, 522mm 3, 54mm 3 and 5mm 3. The volume ratio is 104:11:1.
TABLE 5
As can be seen from Table 5, the entire bottom of 1,2 pentanediol was about 1.7mm deep; the overall bottom of the MPD was on average about 6.1mm deep and the sediment volume was about 4 times that of 1,2 pentanediol.
