Abstract
The present invention relates to novel inorganic Mo-W yellow dye. The chemical formula of the inorganic Mo-W yellow dye is Bi [1-(x+y)/3]M0xWyV[1-(X+Y)]O4 in the production process of the inorganic Mo-W yellow dye, wherein (x+y) is more than or equal to 0.1 and is less than or equal to 0.35; hot water at the temperature of 30 to 70 DGE C is used as the solvent of a precipitant, concentrated ammonia liquor is used for adjusting the reaction acidity of which the pH is more than or equal to 1.5 and is less than or equal to 3.5 so as to shorten the synthesis period; meanwhile, titanium dioxide containing less than 0.1 part of Fe2O3 is used as a bulking agent, not only the cost is reduced, but also the hiding power is obviously improved under the condition that the color saturation of the dye is influenced.
Description
The invention belongs to the manufacturing technology field of mineral dye.
The nontoxic inorganic yellow pigment that with the pucherite is matrix is a noticeable regeneration product in the world today, it is the yellow pigment of matrix with the pucherite that United States Patent (USP) (US-4316746) has proposed two kinds, but technology more complicated, mainly show following 2 points: first, because the solvent of dilute alkaline soln (pH=8～14) as precipitation agent adopted in this invention, for avoiding because Bi
3+Ionic hydrolysis and have influence on reaction uniformity, the adding of precipitation agent must be to drip mode slowly in the reaction process.The second, sodium salt and caustic soda have been adopted in this invention, must make Na
+Ion enters in the throw out.Because Na
+Ionic is residual to be deleterious to pigment performance, so must be through repetitive scrubbing to remove Na after solid-liquid separation
+The ionic step.On the other hand, this invention pigment is with BaSO
4As weighting agent, be a kind of simple blending, only play diluting effect, and pigment performance is not had help.
The objective of the invention is to propose a kind of new be the inorganic molybdenum tungsten yellow pigment of matrix with the pucherite so that adopt fairly simple rational production method; Optimize simultaneously pigment performance, particularly hide the weighting agent that performance has good influence.
Inorganic molybdenum tungsten yellow pigment proposed by the invention has following composition:
Bi〔
1-（x+y）/3〕Mo
xW
yV〔
1-（x+y）〕O

Wherein, 0.1≤x+y≤0.35.
The method for making of this yellow pigment is as follows:
Solubility trivalent bismuth salt is dissolved in (molten intact back pH≤1.25) in the salpeter solution, is made into reaction solution.Ammonium meta-vanadate, ammonium molybdate can be dissolved in then in 30～70 ℃ the hot water, and mix mutually, be made into precipitation agent with the ammonium tungstate solution that obtains behind the ammonia decompose tunstite.This precipitation agent is added in the reaction solution, following reaction mainly takes place:
Because these reactions all produce hydrogen ion, the adding of precipitation agent can not cause Bi
3+Local hydrolysis, so can under well-beaten prerequisite, directly precipitation agent be poured in the reaction solution.After this, continue to stir 15～30 minutes, at this moment pH≤0.6.Can acidity be transferred to 1.5≤pH≤3.5 with strong aqua, restir 15～30 minutes, but stopped reaction then.Place suction filtration after 1 hour, in 90～120 ℃ of oven dry down.Then, calcine more than half an hour down, be cooled to room temperature, grind and then obtain molybdenum tungsten yellow pigment product at 450～700 ℃.
Experiment shows that above-mentioned synthesis reaction temperature can be chosen in 5～95 ℃ of scopes, its optimum temps is 25～60 ℃.
Calcination process must carry out in irreducibility atmosphere.Therefore, must keep calcining under the condition of secluding air not, to finish.
For the opacifying power that improves pigment and reduce cost, can in above-mentioned reaction solution, add and contain 1%(weight) following Fe
2O
3Titanium dioxide.After reaction is finished, calcine more than half an hour down at 550 ℃.The add-on of this kind titanium dioxide can be chosen below (weight) in 4 times of amounts of pigment.
The present invention is owing to adopt hot water to make the solvent of precipitation agent, and adjusts reaction solution acidity with strong aqua, not only can be with in the direct impouring reaction solution of precipitation agent, and saved the remaining NH of flush away
4NO
3Step (NH
4NO
3The time can decompose and influence the performance of product in calcining) thus the synthetic cycle shortened.
The present invention is because the titanium dioxide of introducing contains a small amount of ferric iron, can reduce cost simultaneously and to have significantly improved the opacifying power of pigment under to the very little situation of the influence of paint color saturation ratio.
Inorganic its predominant wavelength of molybdenum tungsten yellow pigment of making according to aforesaid method can be made by lemon yellow tandem product to middle Huang under the condition that changes x, y value etc. between 573～590nm.The colorimetric purity of these pigment series product can reach 83.96%; Producing the primrose yellow pigmenting power with Japan is 100%, and its tinting strength is 60～80g/m

Molybdenum tungsten yellow pigment so that aforesaid method is made is applicable to coloring plastics such as polyolefins.Its color, light fastness are good.This pigment is applicable to that also preparation various coating and paraffin wax product are painted.
