Abstract
A process for preparing modified organic pigment includes such steps as mixing nano titanium oxide, nano zinc oxide and organic pigment with low resistance to sun in ball grinder, and then mixing with nano Si-base oxide to obtain coated organic pigment. Its advantages is high resistance to sun light and low cost.
Description
The present invention relates to nano material SiO
2-xProcess for modifying organic pigment is to make pigment dyestuff improve other method of weathering resistance level through modification.
Pigment has beautified people's life for people have built a colorful world, so the application in the modern life is very extensive.Pigment is divided into pigment dyestuff and mineral dye usually.Mineral dye production is simple, low price, physical strength and heat-resistant stability height, be widely used in the painted of glass, pottery, enamel and partial coating and plastics, but mineral dye color and luster dullness, spectral range is narrow, vividness is poor, tinting strength and colour strength is lower and poor chemical stability; Pigment dyestuff then is to be made of organic substance, the history in existing 136 years of synthetic, at present pigment dyestuff is various in style, chromatogram is complete, lovely luster is bright, tinting strength is high, chemical stability is good and nontoxic, its particle easy grinding, easy dispersion in the use, does not precipitate.In recent decades, the kind and the consumption of pigment dyestuff increase day by day, and its importance has substantially exceeded mineral dye.But the main drawback of pigment dyestuff is that weather-proof (light, heat etc.) property is relatively poor.In addition, pertinent data shows: the output of whole world pigment dyestuff 70% is by five major companies controls such as Hirst company (Germany), BASF AG (Germany), vapour crust-Jia Ji company (auspicious soil), ICI company (Britain), big Japanese ink companies, their product is medium-to-high grade, be the accounting for more than 65% of high-weatherability, but they prepare the technology and equipment more complicated of high-grade pigment dyestuff, and cost is higher.China's pigment dyestuff industry also has very big development in recent years, and annual production at present reaches 30,000 tons, but its low-and-medium-grade products accounts for 70%, and middle-grade product accounts for 29%, and expensive goods only accounts for a little less than in the of 1%.
At the problems referred to above, the purpose of this invention is to provide a kind of through nano silicon-based oxide (SiO
2-x) pigment dyestuff is carried out modification and improves the method for modifying of other pigment dyestuff of weather-proof level.
Nano material SiO provided by the invention
2-xProcess for modifying organic pigment mixes less than 5 pigment dyestuff nano-titanium oxide, nano zine oxide and sun-proof rank earlier in ball mill, add the nano silicon-based oxide mixing again.
The objective of the invention is to realize by the following method: utilize nano-titanium oxide (TiO
2), the ultraviolet absorption characteristic of nano zine oxide (ZnO), it is coated on the surface of pigment particles, absorb to pass and be coated on outermost nano silicon-based oxide (SiO
2-x) UV-light, reach the purpose of comprehensive shielding UV-light.Utilize nano silicon-based oxide (SiO
2-x) have huge specific surface area, surperficial hydroxyl and (OH) reach 48%, have the characteristic of reactable, it is carried out the surface molecular design, and then it is coated on the surface of the organic pigment particles that is enclosed with nano-titanium oxide, nano zine oxide.Utilize nano silicon-based oxide (SiO
2-x) particular optical performance---centering, long wave ultraviolet light (UVA, UVB) reflectivity come reflected radiation to arrive the UV-light on pigment particles surface up to more than 85%.The selected nano-grain of this external cause is little, and it is transparent spreading out, so do not influence the tint permanence of pigment.
Nano material SiO provided by the invention
2-xProcess for modifying organic pigment, prescription between each nano material and the pigment dyestuff is: pigment dyestuff accounts for 68.8-95% (weight percent), nano silicon-based oxide accounts for 3-30% (weight percent), nano zine oxide accounts for 0.5-2% (weight percent), and nano-titanium oxide accounts for 0.5-1% (weight percent).Wherein, nano material is nanometer SiO
2-xThe trade mark is MNIP-0220, nano-TiO
2The trade mark is that MN3J-0830, the nano-ZnO trade mark are MN6Z-1020, and is on sale in the city.
Nano material SiO provided by the present invention
2-xProcess for modifying organic pigment, utilize the natural characteristics of nano silicon-based oxide and some other nano material particular optical performance and nano material that organic pigment particles is carried out surface modification, create the high performance pigment dyestuff product of a class and realize industrial application.In general all improve more than 2 grades through organic pigment permanence to light after the modification.More owing to the further refinement of the quilt of organic pigment particles in ball mill, so its dispersiveness all obtains raising with tinctorial yield.Simultaneously, adopt and not really expensive nano material, use simple technology, centering, low-grade pigment dyestuff carry out modification and obtain high-grade pigment dyestuff, compare cost with the high-grade pigment dyestuff of direct preparation and reduce greatly.Make the performance of improving pigment dyestuff by surface treatment become the dominant direction of pigment dyestuff development from now on.
