It is green and environmentally friendly, and is conducive to ecology The virtuous cycle of the chain; and the new rubber-plastic insulation pipe obtained through the manufacturing process of the present invention has excellent performance and can be widely used in construction and other fields.

The invention discloses a method for producing pigment-level iron oxide red by using titanium dioxide waste residue ferrous sulfate and belongs to the technical field of chemical industry. The pigment-level iron oxide red with excellent performance can be prepared by the method. The method comprises the following steps of: a, removing impurities from the titanium dioxide waste residue ferrous sulfate to prepare a ferrous sulfate solution; b, oxidizing the ferrous sulfate in the solution obtained in the step a to obtain an iron oxide black sediment, and filtering to obtain a filter cake and a filtrate; and c, washing, drying and crushing the filter cake obtained in the step b, and calcining the crushed filter cake to obtain the pigment-level iron oxide red, preferentially, the crushed filter cake is calcined under an aerobic condition, wherein the calcining temperature is 600 to 750 DEG C, and the calcining time is 45 to 60 minutes. The method is low in raw material cost and low in environment pollution; the prepared product has the advantages of bright color and luster, and high tinting strength, oil absorption and dispersibility; and the yield reaches the top standard of an iron oxide red pigment stated by GB 1863-89.

The invention discloses a method for rapidly preparing black iron oxide from ferrous sulfate as a titanium dioxide waste residue and belongs to the technical field of chemical engineering. The method comprises the following steps: a, removing impurities from ferrous sulfate to obtain a ferrous sulfate solution; b, taking a part of ferrous sulfate solution, diluting until the concentration is 10-15%, then introducing air or oxygen, controlling the pH value of the solution at 3-6, controlling the reaction temperature at 20-30 DEG C, and reacting until the color of the solution becomes earthy yellow, so as to obtain a crystal seed liquid; simultaneously and continuously adding the residue ferrous sulfate solution and ammonia to the crystal seed liquid, stirring and heating, controlling the pH value of the solution at 3.0-9.5, controlling the temperature at 70-90 DEG C, while continuously introducing air or oxygen, reacting for 5 to 6 hours, and filtering to a black iron precipitate; c, washing the iron black precipitate, filtering and drying to obtain the black iron oxide product. Since the process for preparing the black iron oxide disclosed by the invention requires only 5-6 hours and has the advantages of short time and low cost, and the method has relatively high economical and social benefits.
