Description
Technical Field
The invention relates to the field of pigments, in particular to color paste for ink of a water-based pen.
Background
The water pen is made of water ink, and is characterized by that it possesses ball-point pen point and the characteristic of no need of sucking ink, and is convenient for use, so that it is a good writing pen variety, and the water pen ink can be dissolved in water, and the water notes written on the non-paper product can be easily erased by using water, and is convenient for use. China is a great pen-making country, but the core technical ink used at present, particularly pigment type ink, basically depends on import, so that the development of color paste for water-based pen ink is very important, and a precursor is provided for the development of water-based pen ink in the later period.
The color paste for the ink of the water-based pen in the prior art is generally characterized by insufficient storage stability, and can generate agglomeration and precipitation after being stored for a certain time, and the state is more obvious after being heated and frozen and thawed, so that the application range of the color paste is limited.
For example, the application number is CN201810658172.6, the red color paste is composed of an organic red pigment, resin, a hyper-dispersant, a wetting agent, an antifoaming agent, a preservative, a pH regulator, a water-soluble organic solvent and deionized water, wherein the particle size of pigment particles is D50-80 nm, D100-250 nm, the red color paste system is stable, does not agglomerate or precipitate and delaminate, has good thermal stability, can be stored for a long time, and is suitable for preparing subsequent gel-ink pens and water-ink pens, but the proportion of pigment components in the formula is small, so the color paste has poor vividness.
Disclosure of Invention
The invention provides the color paste for the water-based pen ink to overcome the defects that the color paste for the water-based pen ink in the prior art has poor storage property, is easy to generate agglomeration and precipitation, and has small pigment component proportion and poor brightness.
In order to realize the purpose of the invention, the invention is realized by the following technical scheme:
color paste for water-based pen ink comprises 50 parts of water, 45-60 parts of toner, 15-25 parts of water-soluble hyperbranched dispersion resin, 10-15 parts of humectant, 5-10 parts of first rheology modifier, 1-5 parts of second rheology modifier, 1-5 parts of pH regulator and 0-5 parts of functional additive;
wherein, the end of the water-soluble hyperbranched dispersion resin has a sulfonic acid group structure;
the first rheology modifier and the second rheology modifier can form unstable cross-linked interpenetrating networks through hydrogen bonds.
The color paste for the water-based pen ink comprises water-soluble hyperbranched dispersion resin, and has a hyperbranched structure, so that the water-soluble hyperbranched dispersion resin has more functional end groups, and the functional end groups are sulfonic structures, so that the water-based pen ink has good clear water property, and can be compatible with groups carried in various toner powders, so that pigment toner can be uniformly dispersed in water, and the stability of the color paste is improved. Meanwhile, the hyperbranched structure can enable toner to enter the inner space of the hyperbranched resin, so that agglomeration and precipitation among the toner are prevented. Meanwhile, the content of the toner in the color paste is higher, so that the color paste prepared by the formula is more vivid in color.
Meanwhile, two different rheology modifiers are added, and an unstable cross-linking interpenetrating structure can be formed between the two rheology modifiers through hydrogen bonds, when the color paste disclosed by the invention is stored, the color paste can lock the color powder so as to prevent the color powder from precipitating and agglomerating, and when the color paste is applied under the action of external stress, for example, in the stirring and writing processes, the unstable hydrogen bonds can be destroyed, so that the viscosity of the color paste can be temporarily reduced, the color paste can be easily and uniformly mixed during stirring and mixing, the fluency of the color paste is not influenced during writing, and after the stress is removed, the hydrogen bonds can be formed again to prevent the precipitation and agglomeration phenomena again.
Preferably, the chemical formula of the water-soluble hyperbranched dispersion resin is represented by the following formula (1):
formula (1)
The inner core of the water-soluble hyperbranched dispersion resin is boron atoms, and the organic silicon structure is grafted outside the boron atoms, and the organic silicon structure has good flexibility, so that the viscosity of the water-soluble hyperbranched dispersion resin is lower than that of linear resin in the prior art by combining the hyperbranched structure of the water-soluble hyperbranched dispersion resin, and the components are more conveniently and uniformly mixed. Meanwhile, the organic silicon structure also has the characteristic of high and low temperature resistance, so that the organic silicon structure can keep the characteristics of the organic silicon structure in the high-temperature and repeated freeze-thaw process in the actual use process, and the problem of dispersion failure is prevented.
Preferably, the preparation method of the water-soluble hyperbranched dispersion resin is as follows:
(S.1) under the protection of nitrogen, dissolving boric acid and triethylamine in an organic solvent, adding the organic solvent into a reaction kettle, dropwise adding diethylchlorosilane into the reaction kettle, and stirring the mixture to react for a certain time to obtain a compound A, wherein the reaction formula is shown as the following formula (2):

The water-soluble hyperbranched dispersion resin is constructed sequentially from inside to outside, so that the structural regularity of the water-soluble hyperbranched dispersion resin can be ensured, the water-soluble hyperbranched dispersion resin has the advantage of regular and controllable structure, the performance of the water-soluble hyperbranched dispersion resin can be kept consistent all the time, and the stability of color pastes in various batches is improved.
Preferably, the toner is one or a combination of several of titanium white, carbon black, ultramarine, iron oxide, monoazo, disazo, condensed azo, phthalocyanine blue, phthalocyanine green, heterocyclic ring and condensed ring ketone pigments.
Wherein: the green pigment includes phthalocyanine pigment, azo pigment or heterocyclic pigment; the yellow pigment includes azo type pigment, azo condensed type pigment and heterocyclic type pigment; the red pigment is selected from PR224, PR254, PR264, PR122, PR123, PR177, PR179, PR190, etc.; the blue pigment is selected from PB1, PB2, PB15:3, PB15:4, PB15:6, PB16, PB22, PB60, etc.

The organic polymer-based rheology modifier can realize the anti-settling stability and the low sagging property through the entanglement of polymer chains, but can possibly cause compatibility problems, for example, the first rheology modifier in the invention takes silica as a base and is organically modified, and a polyacrylamide chain segment is grafted outside the silica-based rheology modifier, so that the silica part can be suspended and dispersed in the color paste, and the polyacrylamide chain segment is dissolved in water and mutually entangled through the chain segment to keep the stability of the color paste.

And the cross-linking network formed by the unstable hydrogen bonds can momentarily break the hydrogen bonds under the shearing condition (such as in the process of coating a roller or brushing), so that the viscosity is reduced, the leveling of the color paste is facilitated, the hydrogen bonds can be formed again under the condition of removing the shearing force, the viscosity is increased again, the anti-sagging performance and the stability of the anti-sagging performance can be ensured, the pigment can be prevented from settling, and the consistency of the final product is ensured.
