Abstract
The present invention provides a method for manufacturing nanometer level calcium carbonate particle for ink. A proper crystal nucleus promoter is added in the initial period of reaction, while the growth rate of the crystal nucleation and every crystal face are conveniently regulated by controlling the gas flow of the carbon dioxide kiln and the initial concentration and temperature of the calcium hydroxide lime cream, a dispersant is added when the carbonization rate reaches over 80% to regulate the calcium carbonate particle surface charge and prevent agglomeration between calcium carbonate particles, thereby the particle size and the appearance are easy to be controlled, and the dispersion properties of the final product can be improved considerably through proper surface treatment. In the invention, the temperature rises naturally by heat release of the carbonization reaction, as a result, the energy consumption for reaching cladding needed temperature and equipment, operating cost are reduced greatly. Obtained cube nanometer level calcium carbonate grows under higher temperature, has lower surface energy density, so it has characteristics of superior brilliance and dispersivity in applications.

Require transparent application scenario as flexographic ink, UV light-curable ink and four-colour chromatography printing ink etc., not only require the calcium carbonate granule divided by maximum granularity less than 40nm, and when being used for ink formulations, have the dispersive of being easy to characteristics.And translucent printing ink calcium is the kind of the most generally using in the resin type printing ink, has to be easy to disperse and good printability, is used to improve the flowability and the levelling property of printing ink.The preparation method commonly used of nano-calcium carbonate has continuous multistage spray carbonation method, hypergravity carborization, stirring tank carborization at present.Multistage spray carbonation method and hypergravity carborization all are to carry out the gas-liquid mass transfer reaction with liquid as disperse phase continuously, increase the gas-to-liquid contact area greatly, strengthened carbonization process microcosmic mix and the microcosmic mass transfer process, easily form a large amount of nucleus in initial reaction stage, can under comparatively high temps, produce nano-calcium carbonate; But continuously multistage spray carbonation method production efficiency is low, and energy consumption is big, and nozzle stops up easily, is difficult to guarantee the uniform distribution of droplet.The facility investment of hypergravity carborization is big, operation easier is bigger, and how this technology keeps in the lab scale process factor such as former strong field distribution to await further further investigation after amplifying.
The stirring tank carborization is the domestic and international at present extensively method of the production nano-calcium carbonate of employing, this method needs strict control carbonization temperature at 10～30 ℃ at whole carbonization process, and the generative process of lime carbonate is thermopositive reaction, therefore needs to adopt huge pressure cooling heat transferring system.The open CN1330039A of Chinese patent application has announced a kind of method that adopts mechanical stirring blended mode synthesis of nano lime carbonate at a lower temperature, then low temperature synthetic calcium carbonate suspension is heated to 45～95 ℃, add surface-modifying agent and handle, make the treated carbonates of 20～90nm; The open CN1332207A of Chinese patent application announced a kind of in 5～35 ℃ of carbonization temperature scopes the synthesis of nano calcium carbonate granule, the pattern that in carbonization process, adds crystalline form conditioning agent control calcium carbonate granule, add dispersion agent and regulate the calcium carbonate granule surface charge, then carburizing reagent synthetic calcium carbonate nano particulate suspension is warmed up between 60～90 ℃, carry out the surface with resinous acids such as rosin and coat processing, obtain between 15～40nm, specific surface area is greater than 35m
2/ g, oil-absorption(number) 40gDOP/100g CaCO
3The printing ink transparent nanometer calcium carbonate.
Because the nano-calcium carbonate that generates is easy to reunite, the calcium carbonate suspension that generally needs to generate is heated to 60～95 ℃, adds corresponding surface treatment agent again and coats processing, just can make the good luster of meeting the need of market, the product good with resin compatible.This shows that prior art is containing significant wastage to energy preparing the method for printing ink with transparent nanometer calcium carbonate and translucent lime carbonate.
