Embodiment 1

[0022] The weight ratio of the raw material formula of this example: the sludge of aluminum profile factory is 65wt%, TiO 2 is 35wt%. The two raw materials were weighed according to the formula, placed in a ball mill for wet grinding for 24 hours, the ground slurry was filtered and dehydrated, dried at 100°C for 24 hours, and crushed to obtain a total material of less than 100 mesh. Adding 7% water to the ground material for mixing, the mixing is uniform, and the mixed material is semi-dry pressed. The formed billet was dried at 100°C for 24 hours, and the dry billet was placed in a kiln for reaction sintering. The reaction sintering temperature was 1400°C, and the reaction sintering holding time was 3 hours. The reaction product was quenched with water to room temperature to obtain the prepared aluminum titanate material.

[0023] The water quenching method is: the product formed by high temperature sintering reaction, the temperature of the product should be higher than 130...

Abstract

The invention provides an aluminum titanate material which is prepared by utilizing sludge of aluminum profile factories and a prepration method thereof, and raw materials of the aluminum titanate material consists of the sludge of the aluminum profile factories and TiO2; the prepration method comprises the following steps: the sludge of the aluminum profile factories and the TiO2 are taken as the raw materials, the raw materials are mixed, the press forming and the high-temperature reaction are carried out, and a reactant is quenched by water, thereby preparing the aluminum titanate material. The preparation method is conducive to the utilization of wastes, the prepared material is high-quality refractory material with high added value and no pollution, the raw materials are easy to obtain, the preparation method has environmental protection and low cost, and the preparation process has strong operationality, thereby having significant economic benefits and social benefits.

Description

technical field [0001] The invention relates to an ecological environment material, that is, the comprehensive utilization of solid waste, and more specifically relates to an aluminum titanate material prepared from sludge from an aluminum profile factory and a preparation method thereof. technical background [0002] Aluminum profile factories will produce a large amount of milky white colloidal waste liquid during the surface treatment of aluminum profiles. The particles in this waste liquid are ultra-fine and highly dispersed. Once discharged directly, it will inevitably cause serious pollution to the environment and river waters, and destroy the ecological environment. . Therefore, a large amount of sludge in the waste liquid must be precipitated and filtered, and the remaining clarified filtrate should be discharged. A large aluminum profile factory can recycle more than 10,000 tons of sludge per year. There are hundreds of domestic aluminum profile companies, which ge...
