Summary of the invention
The object of the invention is to compare by the preparation technology of mica titanium nacreous material and the production technique of method and preparation method's (gas phase cladding and liquid phase deposition), for maturing and practical method have been opened up in the research and development of pearly pigment.
To achieve these goals, the technical scheme that the present invention takes is specific as follows:
One, preparing product type
1, mica titanium nacreous material base material
Mica titanium nacreous material is to take natural mica thin slice as base material, and on its smooth surface, with special production technique uniform deposition, one or more layers has the TiO of high refractive index to light
2or TiO
2with other oxide compound (as: Fe
2o 3, SiO
2deng) pearly pigment made.Because its oxide membranous layer is different from the specific refractory power of mica substrate, and oxide membranous layer is again transparent, light produces multiple reflections, refraction, transmission on mica titanium particle, produce interference of light effect, form high-quality pearlescent effect and shot effects, thereby present soft brilliant, bright and colourful pearl color and luster, and give a kind of far-reaching three-dimensional space texture of people.
2, mica titanium nacreous material type:
Mica titanium nacreous material type is divided into three major types: silvery white colour pattern, iris (illusion-colour) type, colour pattern.Silvery white colour pattern is the basic model of mica titanium nacreous material, is because light does not have transmission at mica titanium surface reflection, thereby only presents single silvery white form and aspect.Iris type is by controlling and regulating the thickness of oxide membranous layer or level to obtain, superficial film forms fabulous pearlescent effect and vision sparkle effect by multiple reflections, refraction and the transmission generation interference effect of light, and produce, dazzles the eyes bright rainbow effect.
3, the rainbow effect of mica titanium nacreous material
Rainbow Titania-Mica Pearlescent Pigment can produce multicoloured rainbow effect, be mainly because: the first, along with mica sheet surface TiO
2the difference of the geometric thickness of rete, its catoptrical path difference is just different, therefore the light generation constructive interference of some wavelength and strengthening, the light generation destructive interference of other wavelength and weakening, thus just there is different reflection interference light color (its transmitted light is its complementary color).The second, when film thickness one timing, while observing Rainbow Titania-Mica Pearlescent Pigment from different angles, it will be appreciated that different colors.When the reflection angle of visual angle in light, can see the strongest interference color; When departing from reflection angle, can only see pearl white or other color, this phenomenon is called goniochromatic effect.The variation of the color being caused by it, is called look and shifts, and maximum look shifts, and can become from a kind of color its complementary color.
Two, production technique and preparation method
The preparation technology of mica titanium nacreous material mainly contains two kinds, gas phase cladding and liquid phase deposition.
1, gas phase cladding, to take volatilizable metallorganics as thing source, with the mica sheet of gaseous form and fluidized state, there is gas-phase reaction under certain condition in reactant, metallorganics decomposes with atomic form, the atoms metal decompositing is oxidized to metal oxide, is deposited on mica sheet surface, and coating and crystallization are once completed, forming the fine and close transparent metal oxide film uniformly of one deck. the method Technology requires high, does not also reach industrialization degree abroad.
2, liquid phase deposition, in aqeous suspension, through stirring, it fully to be disperseed pretreated mica sheet,, by solution reaction, on mica sheet surface, deposit one deck hydrous oxide film under certain condition, more after filtration, wash the post-order processes such as paint, dry, roasting and process and make.
Normally select 5-50 micron and be the white mica substrate through wet pulverization, be made into certain density slurries, regulate pH value to 2.0 left and right of slurries, be warming up to 70～80 ℃, then with certain speed, to solution, add titanium salt solution, this process must slowly be carried out, and conventional titanium salt is TiCl
4and TiOSO

Coating → filtration → washing → dry → roasting → post-processed → product is starched → heated to mica → mica
Several preparation methods that belong to liquid phase deposition, the difference between them is mainly reflected in coating process.
3.1 add alkali neutralisation
Add alkali neutralisation and be and mica slurry is heated to temperature required, then drip TiCl
4solution, in reaction process, titanium salt hydrolysis can produce acid, therefore need add at any time alkali, to control its pH constant.
In this preparation process, pH value is to affect TiCl
4the key of hydrolysis, directly affects the pearl effect of hydrolysis rate and mica titanium nacreous material.Thereby need at stable pH value and suitable temperature, carry out, generally using NaOH solution as alkali lye.
3.2 sandwich of layers coating methods
Sandwich of layers coating method is that to add alkali neutralisation be basis, and only coated oxide compound is different, is used for producing Rainbow Titania-Mica Pearlescent Pigment.That is: by the heating of mica slurry, wherein alternately coated TiO
2layer and SiO
2layer is until present required interference color.
In order to obtain high-quality product, this preparation process need to slowly be carried out, and requires temperature of reaction stable and suitable, and the addition of titanium salt and pink salt is controlled suitably.
