Description
Technical field
The present invention relates to a kind of pigment dyestuff preparation method, be specifically related to the modification technology of the organic yellow PY74 of high covering power.
Background technology
At present; Be applied to the organic yellow PY74 in the self-drying paint, in approaching panchromatic scope, have good fast light, weathering resistance, because this pigment good fluidity; So being used for the high density pigment concentrate slurry can not exert an influence to gloss; Be fit to very much substitute chrome yellow as lead-free pigment, improved the dispersing property in aromatic series or polar solvent system, anti-recrystallization performance.Be organic yellow PY74 in the market, its opacifying power is not strong.
Summary of the invention
The object of the present invention is to provide the modification technology of the organic yellow PY74 of high covering power, the organic yellow PY74 of the inventive method preparation has good fast light, weathering resistance, has high covering power simultaneously.
For reaching above-mentioned purpose, the present invention provides the modification technology of the organic yellow PY74 of high covering power, and concrete steps are:
A. diazotization
Fast Red B base, a spot of purplish red color base GP are poured in an amount of water, under 30 ℃ of temperature, pull an oar beating time 60min;
Add hydrochloric acid then, stir 60min; Generate hydrochloride, be cooled to 10 ℃;
Continue on the rocksly to be cooled to 0-5 ℃, add the good sodium nitrite solution of dissolving simultaneously, stir 90min; After the stirring, add thionamic acid, zeyssatite, filter;
B. change material
Water, liquid caustic soda, ethanoyl acetyl ORTHO ANISIDINE are mixed, be heated to 40-45 ℃, making beating 60min dissolves to complete;
Lower the temperature then, reduce to 30-35 ℃; After the cooling, good Glacial acetic acid min. 99.5 carries out acid out to add dilution, time 30min, acid out to PH be 7.5-8;
Behind the acid out, add sodium-acetate, a small amount of AS, stir, churning time 15min, temperature is controlled at 35-40 ℃;
C. coupling
Diazonium salt is added down in liquid level; Period, temperature was 35 ℃ at 40-50 minute;
Through adding an amount of liquid caustic soda, keeping PH is 5.5～6.5;
Coupling finishes, the no coupling reaction of H acid, and PH is more than 5.5, stirs 30 minutes;
D. resinifying
After the coupling, add rosined soap and resin, and be warming up to 95 ℃;
After the intensification, add an amount of water, liquid caustic soda, hyper-dispersant material, stir, churning time 40 minutes;
After the stirring, temperature is controlled at 80-85 ℃, is incubated 10-15 minute;
E. press filtration, oven dry
Cool the temperature to 60 ℃, carry out press filtration;
Be washed with water to ph=7 then, carry out discharging;
Discharging gained material under temperature 60-75 ℃, is promptly got the organic yellow PY74 of high covering power behind the baking 20-25h.
Beneficial effect: the modification technology of the organic yellow PY74 of high covering power provided by the invention, the organic yellow PY74 of preparation have good fast light, weathering resistance, have high covering power simultaneously.
