Scientific domain.
Background technology
Pigment is main coloring material in nature, develop in recent years it is particularly rapid, although pigment have fastness to light,
The features such as fastness to weathering and solvent resistance are high, and lovely luster is bright, and in weaving, papermaking, building, food, plastics, gold
Belong to the fields such as spraying to be widely used, still, commercialization pigment is mainly with shapes such as aggregation, condensate or floccule bodys
State exists, and particle is thicker and unevenly distributed, causes pigmenting power relatively low, it is impossible to play its pigmentation, therefore, face well
The refinement of material and stably dispersing are its widely applied premises.By adsorbing unimolecule or polymolecular substance such as in surface of pigments
It is current face that the derivative of surfactant, modifying agent, pigment in itself etc., which improves dispersion stabilization of the pigment in medium is used,
Expect one of most common means of fine, but the stably dispersing performance of the dispersion is because of weak intermolecular interaction, easily with
External condition to change and disadvantageous changes occur.
At present, it is more popular grind to improve dispersion stabilization of the pigment in medium is used using chemical grafting method
Study carefully, because of the stability of chemical bond, the dispersion stabilization of dispersion can be improved, so as to effectively prevent the influence of external condition.Tradition
Sol-gel method the inorganic pigment for containing special groups such as-OH primarily directed to surface coated to pigment changed
Property processing, such as pass through the-OH on Si-OH and the inorganic pigment surface of the hydrolysis generation of silanes presoma and generate the side of chemical bond
Nano-inorganic substance is coated on surface of pigments by formula, then utilizes the active group on nano-inorganic substance surface such as-OH, carbon-carbon double bond
Further grafting water group such as-SO3Na ,-COONa.From this, presoma is this technology to the cladding of pigment
It is crucial.Forefathers have successfully coated nano-inorganic substance, such as patent on surfaces such as carbon black, aluminium pigments through the above way
CN104226252A describes the preparation method of a kind of carbon black and composite titania material, i.e., is utilized by sol-gel method
The functional group that carbon black (HCB) surface of surface treatment is formed is combined together with nano-titanium dioxide in the form of chemical bond, most
Afterwards by being prepared into composite material after heat-treatment furnace calcination processing；Patent CN106752121A is prepared for using sol-gel method
Silicon dioxide coating type aluminium pigment etc..But most organic pigment chemical inertia is higher, surface polarity is relatively low, using with nothing
The identical method of machine pigment can not reach good effect.
Forefathers also attempt its surface to be made to become positively charged lotus by way of depositing polyelectrolyte on organic pigment surface, then
The silica that silanes presoma generates under alkaline condition is negatively charged, in this way, using the mode of electrostatic attraction by nanometer
Coated with silica is in surface of pigments, but this mode early period, processing was too cumbersome, need to deposit polyelectrolyte, and organic pigment repeatedly
Stable dispersion is difficult to keep in alcohol solution, nonionic surfactant need to be added in.
