Description
Technical Field
The invention relates to the technical field of high polymer materials, and particularly relates to preparation of a coated iron oxide yellow color master batch.
Background
With the development of society, the application of plastic products has penetrated into various fields of society. By using inorganic pigments of different colors, a plastic product can be given a rich and colorful appearance. However, the plastics as the high molecular organic material have poor compatibility with inorganic pigments, and if the inorganic pigments are not pretreated, the inorganic pigments are difficult to be uniformly dispersed in the plastics, thereby affecting the appearance quality and the service life of the product.
Yellow iron oxide, also known as iron oxyhydroxide, having hydroxyl functional groups on its surface, is not useful as a colorant in two ways: poor heat resistance and poor dispersibility. At present, the easily dispersible iron oxide yellow on the market is mainly obtained by physical method (mechanical grinding), but during grinding production, dust is easily generated, the environment is polluted, and the health of workers is harmed. The easily dispersible iron oxide yellow can also be obtained by chemical treatment. The invention discloses a method for preparing easily-dispersible iron oxide yellow by modifying the surface of ammonia process iron oxide yellow (CN 201410440986.4). The invention uses water as a medium, and adopts a stirring and beating mode to pretreat an ammonia process iron oxide yellow filter cake to obtain slurry with uniformly dispersed water phase, and then adds a super dispersant emulsion, and utilizes the hydroxyl group of the iron oxide yellow and the anchor group of the amino group of the super dispersant to form a hydrogen bond under a certain pH condition, and the solvation chain of the super dispersant coats the iron oxide yellow to modify the surface of the iron oxide yellow to obtain the easily-dispersible iron oxide yellow dispersed particles. Chinese application patent (CN 201710310972.4) discloses a heat-resistant easily-dispersible iron oxide yellow pigment and a preparation method thereof. Soluble calcium salt, sodium hexametaphosphate and sodium hydroxide are used as reaction raw materials, an ultrasonic dispersion technology is introduced in the coating process, calcium phosphate is coated on the surface of the iron oxide yellow pigment through reaction, and then organic treatment and modification are carried out on the surface of the iron oxide yellow pigment, so that the formed composite material improves the heat resistance and the dispersibility of the iron oxide yellow and can be used as a coloring agent in plastic processing and powder coating application. The Chinese application patent (CN 201810194542.5) adopts a high-temperature high-pressure powder depolymerization dispersion technology, the heat resistance of the iron oxide yellow is improved by a composite material formed by coating the iron oxide yellow with aluminum oxide and zinc oxide, the composite material can be used as a coloring agent and a preservative when being applied to plastic processing and powder coating, and the zinc oxide can inhibit the generation of a later-stage iron oxide yellow red phase to a certain extent so as to ensure that the color is purer.
From patent analysis, many existing patents are directed to improving the heat resistance and poor dispersion of iron oxide yellow by coating the iron oxide yellow with an inorganic material. The application of iron oxide yellow coated with organic materials in color masterbatches is rarely reported.

③ putting the emulsifier, the ferric oxide yellow grafted with silane and ultrapure water into a flask, heating to 65-75 ℃, starting stirring, controlling the rotating speed at 800-900 r/min, and stirring for at least 30 minutes to uniformly mix the priming materials;
adding an initiator into a reaction bottle, and after the temperature is stable;
dripping the acrylate compound into the reaction system by using a constant-pressure dropping funnel;
controlling the dripping time to be 1 hour, and preserving the heat for 1 hour after the dripping is finished;
after the reaction time is over, cooling to 45 ℃, and filtering to obtain coated iron oxide yellow;
④ mixing ABS resin, heat-resistant agent and toughening agent in a high-speed mixer for 3-5 minutes, adding antioxidant, light stabilizer, lubricant and coated iron oxide yellow into the high-speed mixer for 3-5 minutes, adding the mixed particles into a double-screw extruder for melt extrusion, granulation, drying, cooling and packaging, wherein the rotation speed of the high-speed mixer is 200-600 r/min, and the rotation speed of the high-speed mixer is 700-1000 r/min.
