Preparation method of lining material for furnace for producing white carbon black

Abstract

The invention provides a preparation method of a lining material for a furnace for producing white carbon black and relates to the field of new materials. The preparation method comprises the steps of dissolving hydrochloric acid in deionized water to obtain an acid liquid; dissolving vanadium (III) acetylacetonate in deionized water to obtain vanadium (III) acetylacetonate solution; mixing basic zirconium carbonate with deionized water to obtain basic zirconium carbonate mixed liquid; adding deionized water to bentonite to obtain bentonite suspension; adding the basic zirconium carbonate mixed liquid into the bentonite suspension, stirring for 2 h, adding the acid liquid during stirring, and regulating pH to 4.8; adding the vanadium (III) acetylacetonate solution, stirring for 1.5 h, and standing and aging for 10 h to obtain a slurry; filtering, washing filter cakes with deionized water until there is no Cl-, and drying; grinding to obtain the lining material for a furnace. The lining material of the invention is suitable for the furnace for producing white carbon black and may act as a lining material for a furnace to avoid the direct contact between production materials for white carbon black and a furnace body, improve product purity, and prolong the life of the furnace.

Description

technical field [0001] The invention relates to the field of new materials, in particular to a method for preparing a furnace lining material used for producing white carbon black. Background technique [0002] In the prior art, the production process of white carbon black is to uniformly mix quartz sand and soda ash, and treat them at high temperature in a furnace. Furnaces used for high-temperature treatment, due to their bulky size, are mostly built with fire protection. In order to produce products with higher purity and improve the service life of the furnace, a lining structure needs to be installed inside the furnace to isolate the material from the furnace body. However, there is currently a lack of a furnace lining material suitable for producing white carbon black. Contents of the invention [0003] The object of the present invention is to provide a kind of preparation method for the lining material of the melting furnace for producing white carbon black, to so...
