The polymer type organic pigment has no harm to human bodies and no pollution to environment and is easily degradable in natural environment. No organic solvent or harmful substance is used and no volatile organic compound is generated during the production technique process of the pigment. The synthesizing technique of the invention is simple without any special technique equipment and has low cost. The pigment of the invention has good tinctorial strength, color and brightness, thereby being used for fields of printing ink, coating material, paint and so on.
Description
Technical field
The present invention relates to pigment, specifically belong to a kind of polymer type organic pigment and preparation method thereof.
Background technology
Pigment is widely used in every field such as coating, paint, printing ink, and people's life is had very big influence.Traditional pigment is divided into mineral dye and pigment dyestuff.Much contain heavy metal in the mineral dye, bigger to the harm of human body; Pigment dyestuff generally in process of production owing to an organic solvent production environment is produced pollution, causes certain harm to workers'health; Existing inorganic, generally very difficult degraded voluntarily in physical environment of pigment dyestuff causes secondary pollution easily.
The preparation method of Chinese patent application number a kind of polymer-type white pigment dyestuff for ZL200310112156.0 discloses, this method is with vinylbenzene, acrylic monomer or unsaturated monomer, with high acid value, low-molecular-weight acrylic resin is a dispersion resin, the tensio-active agent two-in-one with negatively charged ion and nonionic is emulsifying agent, with the persulphate is initiator, under 60-80 ℃ of condition, carry out 2 step seeded emulsion polymerizations, the synthetic latex grain is " nuclear/shell " double-deck emulsion, under comparatively high temps, make the emulsion particle swelling of emulsion more earlier with the organic solvent of a small amount of higher, make further swelling of emulsion particle and pore-forming with alkaline matter again, by certain optical effect, make polymer particle obtain whiteness preferably.When the polymer-type white pigment dyestuff that this preparation method makes is used for preparing water-borne coatings or water color ink, be easy to disperse, weather resisteant is good, not easy to change, good with other component compatibility in the product, can significantly improve the stability in storage and the viscosity stability of water-borne coatings or printing ink, and not have toxicity substantially.But the used raw material high polymer monomer of this pigment is vinylformic acid, vinylbenzene and other unsaturated monomer, and these monomers have pungency to skin and mucous membrane; This pigment is done initiator initiation reaction preparation, reaction process complexity with persulphate; And product has only single white.
Chinese patent application number is that 03128922.3 to disclose a kind of be the pigment dyestuff and preparation method thereof of nuclear with the hyperbranched polymer.React in organic solvent by hyperbranched polymer and dyestuff and to obtain, the weight ratio of hyperbranched polymer, dye well organic solvent is 1: 0.1-10: 10～100, temperature of reaction is 10-180 ℃, reaction times is 10 minutes-24 hours, through the precipitation agent precipitation, filters again, dry, the gained organic pigment particle is micron or nanoscale particle diameter, and good stability is applicable to fields such as coating, polymer composite, photoelectric functional materials.But this pigment is to react to make in organic solvent, and organic solvent can produce volatile organic matter (VOC), causes polluting; The polymer that is adopted is polyethers, polyester-polyurethane etc., and certain pungency is all arranged; The dyestuff that is adopted is general organic dye, can cause secondary environmental pollution; Used precipitation agent comprises organic solvent, has improved production cost.
Summary of the invention
The purpose of this invention is to provide a kind of polymer type organic pigment and preparation method thereof, this pigment is degraded easily in physical environment, in process of production not with an organic solvent.
The preparation method of a kind of polymer type organic pigment provided by the invention comprises the steps:

(2) reaction product is centrifugal, to filter, be washed to filtrate be colourless, the water-insoluble product;
(3) with water-insoluble product drying, dispersion grinding obtains polymer type organic pigment.
Described water-soluble high-molecular material is selected from polyoxyethylene glycol, polyvinyl alcohol, Zulkovsky starch or carboxymethyl cellulose;
Described reactive dyestuffs are selected from Reactive Light Yellow X-6G, reactive yellow X-R, reactive brilliant yellow X-7G, active gorgeous yellow X-5G, reactive scarlet BES, reactive scarlet B-EF, reactive red-violet X-2R, Reactive blue X-R, reactive yellow K-RN, reactive golden yellow K-2RA, reactive brilliant orange K-R, active purple k-3r, reactive violet KN-4R, reactive brilliant yellow KM-7G, reactive dark blue KM-GR, reactive dark blue K-R, active navy blue BET, activity red engleri K-B 3 R, active green KE-4B, reactive dark green B-4BL, reactive violet B-5RV, reactive black VB, Reactive Black GR X, reactive black BES or reactive black BED.
Described catalyzer is one or more in sodium sulfate, sodium hydroxide, yellow soda ash and the sodium bicarbonate; The mode that adds catalyzer is disposable adding or adds in batches.
Compared with the prior art, advantage of the present invention and effect: the present invention is that main raw material is prepared from water-soluble high-molecular material and environmental protection dyestuff, and is harmless, degraded easily in physical environment, environmentally safe; The pigment production technological process is without organic solvent and objectionable impurities, and the non-volatility organism produces, and belongs to green production process; Synthesis technique of the present invention is easy, does not need special processing unit, and cost is lower; Pigment of the present invention has good tinting strength, color and luster and brightness, can be used for fields such as printing ink, coating, paint.
