Abstract

The invention discloses a method for preparing ferrozirconium red stain, which is characterized by comprising the following steps in turn: (1) liquid-phase reaction, which is to perform liquid-phase reaction on zirconium oxychloride, ferrous sulfate and sodium metasilicate pentahydrate in water; (2) separation and drying, which is to separate and dry solid-liquid suspended substances generated by liquid-phase reaction; (3) precalcination, which is to crush dried substances and calcine the crushed substance for 2 to 3 hours at a temperature of between 750 and 850 DEG C; (4) mixing, which is to mix products of precalcination uniformly with lithium fluoride, sodium fluorosilicate and sodium fluoride; (5) calcination, which is to calcine the mixture in the four step for 2 to 5 hours at a temperature of between 900 and 1,000 DEG C; and (6) post processing, which is to treat sintered solid substances by grinding, acid washing, water scrubbing, drying and sieving. The method for combination of liquid-phase reaction and solid-phase reaction improves the encapsulation rate of high-temperature solid-phase reaction, and synthesizes ferrozirconium red stain products which have beautiful chromogenic colors and strong chromogenic force and are stable at high temperature.

Description

technical field [0001] The invention relates to a preparation method of iron-zirconium red material. Background technique [0002] Iron zirconium red material belongs to the encased zircon pigment, in which the colored iron oxide is wrapped by ZrSiO4 crystals and appears red. [0003] The production technology of the previous iron-zirconium red material mainly adopts the synthesis process of traditional ceramic color materials, mainly including weighing and mixing, calcining, washing and pickling, crushing and other processes. The specific process is as follows: [0004] Mixing: Mix the raw materials zirconia, silicon dioxide, red iron oxide and mineralizer together evenly. [0005] Calcination: The mixed material is calcined in a high-temperature kiln, and the material undergoes a high-temperature solid-phase reaction in the kiln to synthesize a color product. [0006] Washing and pickling: After washing and pickling, the insufficiently synthesized raw materials are washe...
