Description
Technical field
The present invention relates to aqueous color paste field, and in particular to a kind of preparation method of environment-friendly nano water-based mill base.
Background technology
With the increasingly raising of people's quality of the life, the requirement to daily necessities, the appearance color of living environment is also continuous
Rising, so the research and development of the visual effect and chromaticity to product is more and more deep.It is well known that pigment is one
Kind coloring material, pigment have higher fastness to light, fastness to weathering and solvent resistance, and the lovely luster of pigment becomes clear,
It is widely used in fields such as weaving, papermaking, building, food, plastics, metal sprayings.Pigment as a kind of colouring agent,
Want uniform, be dispersed stably in medium, be configured to mill base, to ensure that mill base particle diameter reach minimum as far as possible in process for preparation
Value, and particle diameter distribution is uniform, so can just make the amalgamation of mill base and stability more preferable, it is wider in key, key areas
Using simultaneously because the environmental consciousness of people constantly strengthens, and aqueous color paste is more prominent in the effect of field of Environment Protection, so water
Property mill base research and application also increasingly favored, then there is an urgent need for a kind of ring that can be widely applied to high-end field
Guarantor's type mill base.
Also there is the product of some nano color pastes in the market, such as Publication No. CN101629038A invention
Patent, in " a kind of production method of water nano mill base for digital ink-jet and the container with ultrasonic generator ", carry
Go out a kind of nano color paste of material particular diameter fineness in 150-250nm, Publication No. CN101760088A patent of invention,
In " color paste for nanometer modified environmentally-friendly ferric oxide machine and preparation method ", it is proposed that a kind of particle diameter distribution reaches D99 less than 1um's
Mill base, Publication No. CN101747687A patent of invention, " sub-nano golden yellow water-based color paste for hydrophilic coating and its preparation
In method ", it is proposed that a kind of D99 is less than 1.2um mill base, in other similar patents, particle diameter that mill base can reach also base
This is in equivalents, from above-mentioned patent, it will be seen that the particle diameter of these " nano color pastes " or " sub- nano color paste "
Actual other all in a Subnano-class, not real nano color paste, these mill base particle diameters are larger, skewness, in reality
Not only it is difficult to show good visual effect during the use of border, chromaticity, while the water of these mill bases can not be ensured again
Property degree is not high, environmental protection standard is unable to reach, so these mill bases still can not widely be applied.
The content of the invention
It is an object of the present invention to be directed to above-mentioned the deficiencies in the prior art, a kind of environment-friendly nano water-based mill base is proposed
Preparation method.Mill base particle diameter made of this kind of preparation method is small, the uniformity is high, while Water-borne modification degree is high, possesses good ring
Guarantor property, application is more extensively and high-end, also ensure that the quality and value of ink-jet produced print.
A kind of preparation method of environment-friendly nano water-based mill base, comprises the following steps：
1）, pigment, surfactant, solvent be well mixed, obtain mixed liquor A；
2）, abrasive media is added into mixed liquor A, obtain blend, and carry out scattered grinding；
3）, the blend by scattered grinding will be ground medium separating and filtering, obtain mixed liquid B；
4）, by mixed liquid B carry out particle diameter screening and filtering, obtain final products.
Preferably, the mixed liquor A, blend and the mixed liquid B temperature in preparation process are respectively less than or equal to 40 DEG C, by
Clustering phenomena can be caused in temperature is too high, so in mill base preparation process, to keep certain temperature range, make color obtained by preparation
The uniformity of slurry can be ensured preferably.
Preferably, the preparation method step 1）Described in pigment there is transparent characteristic, preferably Hua Yinghuang 150.
Preferably, the preparation method step 1）Described in surfactant originate from a gram Lay benefactor department model DIP, the type
Number surfactant has stronger surface-active compared to the surfactant of other models, while also there is stronger wetting to make
With can more fully make the compatibility in mill base between each component stronger.
Preferably, the preparation method step 1）Described in solvent be aqueous solvent, preferably glycerine and deionized water, because of water
Property nontoxic solvent it is harmless, production and using when injury to operator greatly reduces, while select glycerine and deionization
Water is on the one hand both at non-toxic solvent, on the other hand adding glycerine can make ink-jet effect have more light as solvent
Pool property.
Preferably, the preparation method step 2）Described in mixed liquor and abrasive media mass ratio be 1:2.5, it is described to grind
Grinding media is 95 zirconium pearls, and Mohs' hardness is not less than 9 grades, and the ratio of abrasive media and hardness are to grinding effect in process of lapping
Have considerable influence, thus the selection of mixed proportion and hardness of abrasive media be that comparison is crucial.
Preferably, the preparation method step 2）Described in disperse grinding rate of dispersion be 4300r/min~4700r/
Min, the zirconium pearl under the rate of dispersion can obtain very high kinetic energy, in scattered grinding abrasive media and with mixed liquor
The mutual shock of grain is more violent, and jitter time is 7~9h, can more effectively improve the uniformity of the granularity of mill base.
Preferably, the preparation method step 3）Described in abrasive media separating and filtering using being less than or equal to 150 purposes
Steel net.
Preferably, the preparation method step 4）Described in particle diameter screening and filtering use vacuum pump using circulatory water filtered off with suction device
Filtered by filter membrane, traditional filtering is substituted using vacuum filtration, makes filter effect more preferable, is not easily introduced impurity, while can
Save the plenty of time.
Preferably, the filter membrane specification is less than or equal to 0.45 μm, and material is glass fibre.
Compared with prior art, the invention has the advantages that and beneficial effect：
By preparation method of the present invention, it can obtain that a kind of mill base particle diameter is small, and particle diameter distribution is uniform, while environmentally friendly rank
High, in stable condition aqueous color paste.Because the mill base particle diameter is smaller, nano-scale is reached, and particle diameter distribution is uniform, institute
It is very strong with the applicability of the mill base, it can be widely used in each crucial, high-end field；The mill base has many good stabilizations
Property, in long-term storage, product is not easy to be layered, is denatured；The environment-friendly type solvent of mill base selection simultaneously, in the production and use process
Higher environmentally friendly rank is can reach, more expands its use range, is especially suitable for users under present society environment
Active demand.
