Background technology
Pigment yellow 17 is a kind of azo pigment, has water-fast feature.Because it is water insoluble, under some aqueous systems, purposes and the space of pigment yellow 17 will be constrained.In order to expand the Application Areas of pigment yellow 17, a lot of people to attempt pigment yellow 17, as microemulsion or emulsion, being become not having of microemulsion at present, because its structure decides to do, to become microemulsion difficulty larger.As emulsion, current research is also less, and the effect obtained is very not remarkable, still there is a lot of shortcomings, constrains its large-scale application.
Summary of the invention
The technical problem solved: yellow 17 emulsion particle diameters of convention pigment are large, the problem of poor stability.
Technical scheme: the preparation method that the invention discloses a kind of pigment yellow 17 emulsion, preparation method comprises the following steps: (1) gets order number be 400 ~ 500 object pigment yellow 17 powder is 10 ~ 12 parts, and pigment yellow 17 is put into container; (2) in container, adding Glycerin, mixed triester with caprylic acid capric acid is 5 ~ 9 parts, is mixed by pigment yellow 17 with Glycerin, mixed triester with caprylic acid capric acid, is A mixture; (3) separately get a container, in container, add polyoxylethylene abietate is 20 ~ 24 parts, then to add petroleum sodium sulfonate be 18 ~ 25 parts, then adds water and be 160 to 170 parts, mixes as B liquid; (4) mixed with B liquid by A mixture, use shears to shear 10 ~ 20min, rotating speed is 6000rpm to 8000rpm; (5) shearing terminates rear preservation.Pigment yellow 17 powder order number is preferably 500 orders.Pigment yellow 17 powder is preferably 12 parts
.glycerin, mixed triester with caprylic acid capric acid is preferably 5 parts.Shears shear time is preferably 20min.
Beneficial effect: it is very little that this preparation method prepares pigment yellow 17 emulsion particle diameter is 10um ~ 16um.There is good thermal stability and dewatering ability simultaneously.Emulsion heats 5 ~ 10h and demixing phenomenon does not occur at 50 DEG C.Under rotating speed is 4000rpm, centrifugal 30min ~ 60min does not have layering and demulsifying phenomenon to produce yet in addition.
Embodiment
Embodiment 1
(1) to get order number be 400 object pigment yellow 17 powder is 10kg, and pigment yellow 17 is put into container; (2) in container, adding Glycerin, mixed triester with caprylic acid capric acid is 9kg, is mixed by pigment yellow 17 with Glycerin, mixed triester with caprylic acid capric acid, is A mixture; (3) separately get a container, in container, add polyoxylethylene abietate is 24kg, then to add petroleum sodium sulfonate be 25kg, then to add water be 160kg, mixes as B liquid; (4) mixed with B liquid by A mixture, use shears to shear 10min, rotating speed is 6000rpm; (5) shearing terminates rear preservation.
Embodiment 2
(1) to get order number be 500 object pigment yellow 17 powder is 11kg, and pigment yellow 17 is put into container; (2) in container, adding Glycerin, mixed triester with caprylic acid capric acid is 5kg, is mixed by pigment yellow 17 with Glycerin, mixed triester with caprylic acid capric acid, is A mixture; (3) separately get a container, in container, add polyoxylethylene abietate is 20kg, then to add petroleum sodium sulfonate be 23kg, then to add water be 170kg, mixes as B liquid; (4) mixed with B liquid by A mixture, use shears to shear 20min, rotating speed is 7000rpm; (5) shearing terminates rear preservation.
Embodiment 3
(1) to get order number be 450 object pigment yellow 17 powder is 12kg, and pigment yellow 17 is put into container; (2) in container, adding Glycerin, mixed triester with caprylic acid capric acid is 7kg, is mixed by pigment yellow 17 with Glycerin, mixed triester with caprylic acid capric acid, is A mixture; (3) separately get a container, in container, add polyoxylethylene abietate is 22kg, then to add petroleum sodium sulfonate be 18kg, then to add water be 165kg, mixes as B liquid; (4) mixed with B liquid by A mixture, use shears to shear 15min, rotating speed is 8000rpm; (5) shearing terminates rear preservation.
Particle diameter, thermostability, dewatering ability mensuration have been carried out to the product of embodiment 1, embodiment 2, embodiment 3.Result is as following table.
The product prepared has possessed good thermostability and dewatering ability.
