Description
Technical field
The present invention relates to a kind of making of particulate oxidation iron oxide red pigment, relate to specifically improve particulate oxidation iron oxide red faceThe method of material form and aspect, belongs to chemical color field.
Background technology
Common ferric oxide red colorant is Powdered, has certain difficulty at aspects such as transport, metering, packaging, dust, thanAs transport and packaging aspect, common iron oxide red proportion is less, relative volume is larger, cost of transportation is higher. In meteringAspect, common ferric oxide red colorant is owing to being Powdered, mobility is poor, has larger difficulty in metering process. SeparatelyExternal dust and environmental protection aspect, ordinary powder iron oxide red easily causes dust pollution to environment, and operating personnel are had to phaseWhen large harm, easily cause occupational disease, so being made into granular iron oxide red, pulverous iron oxide red just can changeBe apt to the problem at aspects such as transport, metering, packaging, environmental protection, but after the iron work of particulate oxidation, pigment also can exist certainShortcoming, such as the dispersed variation of pigment, form and aspect variation, the problems such as tinting strength, tinting power variation, at present You Hen many enterprises on the marketCan produce voluntarily particulate oxidation iron oxide red pigment, and the intensity of particulate oxidation iron and circularity can both reach use standard,But due to pigment has been used to binding agent, cause pigment particles to be reunited comparatively violent, so in particulate oxidation iron manufacturing processIn often all can exist pigment-dispersing to decline problem, dispersed decline easily causes pigment colour mutually poor, the most at lastCause use amount to increase.
Although a lot of enterprises can add sodium carboxymethylcellulose, lignin salt in the process of producing particulate oxidation iron oxide redEtc. the dispersant of type, the Chinese patent application that application number is 200510062400.6 provides with calgon as dispersionThe technology of agent, only has 103% but result is tinting strength, tinting power, does not reach the object of our expection. Finding one can be largerThe dispersant that degree improves pigment-dispersing is also equipped with suitable pigment colour phase modifier, make the form and aspect of pigment and granulation itFront constant or better before than granulation, become one of most important link in particulate oxidation iron oxide red pigment production process.
Summary of the invention
The object of the invention is to overcome the deficiency that prior art exists, and provide a kind of manufacture craft simple, cost is low,Tinting strength, tinting power is greatly improved, and has reduced the use amount of pigment, the raising particulate oxidation iron that client's production cost is reducedThe method of red form and aspect.
The object of the invention is to complete by following technical solution, described one improves particulate oxidation iron oxide red pigmentThe method of form and aspect, the method is: utilize the aqueous solution of dispersant, binding agent and form and aspect conditioning agent to mix, even after mixingBe sprayed on the particle of ferric oxide red colorant, make mixed solution be penetrated into the granule interior of each ferric oxide red colorant.
As preferably: described dispersant comprises in the poly-naphthaldehyde sulfonate sodium of sulfonate and sodium metnylene bis-naphthalene sulfonateOne, preferably poly-naphthaldehyde sulfonate sodium; The consumption of this dispersant is controlled at the 0.08%-of ferric oxide red colorant mass fraction0.16％；
Described binding agent is selected sodium metasilicate, and the consumption of this binding agent is controlled at ferric oxide red colorant mass fraction0.4％-0.8％；
Described form and aspect conditioning agent is selected urea, and the consumption of this form and aspect conditioning agent is controlled at ferric oxide red colorant mass fraction0.008%-0.016%.
As preferably: described method comprises the steps:
A) sodium metasilicate that takes ferric oxide red colorant mass fraction 0.4%-0.8%, as binding agent, is dissolved in sodium metasilicateTemperature is that in the water of 40-50 degree Celsius, dissolution time is 2.5-3.5 hour, is mixed with the sodium silicate aqueous solution of 70-90kg;
B) add ferric oxide red colorant mass fraction 0.08%-0.16% to gather naphthaldehyde sulfonate sodium, Asia after having dissolvedOne in methyl sodium dinaphthalenesulfonate is as dispersant and the conduct of ferric oxide red colorant mass fraction 0.008%-0.016% ureaForm and aspect conditioning agent dissolves jointly, and dissolution time is controlled at 10-20 minute;
C) in granulating disc with under 35-50kg/min rotary speed, add iron oxide red particle and simultaneously spray configurationGood auxiliary agent, makes it balling-up; Rotary speed when balling-up is controlled at 20-25 turn/min, the balling-up time is controlled at 25-35 minute;
D) moisture of final particle is 8.0%, then sieves the 110-130 degree Celsius of oven dry of rolling.
Common dispersant is easy and sodium metasilicate interaction reduction is dispersed, thereby then reduces again the caking property of sodium metasilicateReduce adhesion strength; And a lot of dispersant solutions have certain viscosity and cause shower nozzle atomizing effect poor, and granulation process is pastToward there being good atomizing effect, so the bad meeting of atomizing effect causes particle balling preparation poor, the present invention uses poly-naphthaleneA kind of dispersant in formaldehyde sulfonate sodium, sodium metnylene bis-naphthalene sulfonate and the mixed aqueous solution of urea, fully penetrate into pigmentParticle surface can reduce the surface of pigment particles, makes it in medium, under the effect of mechanical force, more easily disperse, and thisTwo kinds of dispersant solutions itself do not have viscosity, and very easily dissolve.
It is simple that the present invention has manufacture craft, and cost is low, and manufacture craft is simple, and cost is low, and tinting strength, tinting power is significantly carriedHeight, has reduced the use amount of pigment, and client's production cost is reduced, and can significantly improve the spies such as particulate oxidation iron oxide red pigment form and aspectPoint.
