Abstract
The invention discloses the synthetic method of a kind of attapulgite/dihydroxyphenyl propane hybrid pigment, the method puts in reactor by the weight such as attapulgite and deionized water, add the dihydroxyphenyl propane of the 70-80% being equivalent to attapulgite hygroscopicity value again, stir, open cold condenser and agitator, and be warming up to 70-80 DEG C, start intercalation, positively charged ion composite catalyst is added after 5-6h, make system PH=7-9, then at 80-90 DEG C, fixation reaction and color reaction is carried out, heating is stopped when the aberration of color reaches standard aberration, after reaction terminates, material is sent in spray-dryer and is carried out drying treatment by direct vacuum pump, when the water content of material is 0.2-0.3%, by mesh-of-grind in the pigment of drying feeding Raymond mill to 1000-1500 order.This pigment acid-and base-resisting and organic solvent, good stability, inexpensive, be widely used in ink, the fields such as colo(u)r coating.
Description
Technical field
The present invention relates to the synthetic method of a kind of attapulgite/dihydroxyphenyl propane hybrid pigment, belong to pigment dyestuff technical field.
Background technology
Pigment dyestuff is in bright gay color, strong coloring force, and density is little, good dispersity, not easily precipitates, and is widely used in the fields such as ink, coating, rubber item, plastics, school supply and stationery and material of construction.But weather-proof, the acid-and base-resisting of existing pigment dyestuff and organic solvent-borne are not as mineral dye, poor stability, fade fast, cost is high.
Summary of the invention
The object of the invention is to for the deficiencies in the prior art, the synthetic method of a kind of attapulgite/dihydroxyphenyl propane hybrid pigment is provided, the method is that carrier is reacted into pigment with the organic compound dihydroxyphenyl propane hydridization that can provide-OH chromophoric group with attapulgite, obtained hybrid pigment good endurance, the life-span is long-range.
The technical solution used in the present invention is as follows:
The synthetic method of a kind of attapulgite/dihydroxyphenyl propane hybrid pigment, it is characterized in that, the weight such as attapulgite and deionized water is put in reactor, add the dihydroxyphenyl propane of the 70-80% being equivalent to attapulgite hygroscopicity value again, stir, open cold condenser and agitator, and be warming up to 70-80 DEG C, start intercalation, positively charged ion composite catalyst is added after 5-6h, make system PH=7-9, then at 80-90 DEG C, fixation reaction and color reaction is carried out, heating is stopped when the aberration of color reaches standard aberration, after reaction terminates, material is sent in spray-dryer and is carried out drying treatment by direct vacuum pump, when the water content of material is 0.2-0.3%, the pigment of drying to be sent in Raymond mill mesh-of-grind to 1000-1500 order or press pigment standard fineness.
Described positively charged ion composite catalyst is by NaOH, Ba (OH)
2, MgO and Zn (OH)
22-3:3-4:1:0.4-0.8 mixes in molar ratio.
Beneficial effect of the present invention:
Montmorillonite in attapulgite composition of the present invention, there are exchange and intercalation two kinds of importance, utilize intercalation compounding the chromophoric group (-OH) of organic compound dihydroxyphenyl propane can be introduced into the sheet interlayer of montmorillonite, make the iron ion (Fe in oh group and montmorillonite or attapulgite
3+) or iron protoxide (Fe
2o), under the effect of catalyzer, there is color reaction, thus obtain inorganic-organic hybridization pigment.The color of this pigment is determined by metal ion in the active group in organic compound and attapulgite composition.Make carrier organic compound with attapulgite and make hybrid and the red pigment of synthesizing is durable pigments, its not only resistance to biological degradation, and acid-and base-resisting and organic solvent, good stability.It is a kind of weather resistance artificial material be encapsulated in by pigment dyestuff in attapulgite, and inexpensive, therefore wide market, is widely used in ink, the fields such as colo(u)r coating.
Embodiment
200kg attapulgite and 200kg deionized water are put in reactor, add again be equivalent to attapulgite hygroscopicity value 80% dihydroxyphenyl propane, stir, open cold condenser and agitator, and be warming up to 80 DEG C, start intercalation, positively charged ion composite catalyst is added after 6h, make system PH=7-9, then at 85 DEG C, fixation reaction and color reaction is carried out, heating is stopped when the aberration of color reaches standard aberration, after reaction terminates, material is sent in spray-dryer and is carried out drying treatment by direct vacuum pump, when the water content of material is 0.3%, the pigment of drying to be sent in Raymond mill mesh-of-grind to 1500 order or press pigment standard fineness.
Described positively charged ion composite catalyst is by NaOH, Ba (OH)
2, MgO and Zn (OH)
22:3:1:0.5 mixes in molar ratio.
The red pigment of above-mentioned synthesis is used as the pigment in ink, add-on 15%, flexible convex printing ink made after sand mill grinding is after printing, and the dispersiveness of its pigment in low-melting ink vehicle, the color saturation of institute's impression literary composition and brightness all meet the requirement of ink industry.
