Abstract

The invention provides a method for preparing a TiO2 / powdered quartz composite powder material. In the invention, the used powdered quartz is a nucleated substrate, crystalline TiO2 is a coating material, the surface of the nucleated substrate is coated and modified with TiO2 by reaction in a mechanical and chemical modifying mode in a wet-process superfine grinding system, and thus, the TiO2 / powdered quartz composite powder material is prepared. In the composite powder material disclosed by the invention, the TiO2 is uniformly coated on the surface of the powdered quartz particles and is stably bonded with the surface of the powdered quartz particles. The powder material has high covering performance, dye performance such as high compatibility with an application system and high acid and alkali resistance. The TiO2 / powdered quartz composite powder material can be used in place of natural titanium white.

Description

Technical field

[0001] The present invention relates to a kind of TiO 2 The invention discloses a method for preparing a powder quartz composite powder material, which belongs to the field of non-metallic mineral processing and the field of environment-friendly materials. Background technique

[0002] Titanium dioxide (pigment grade titanium dioxide), as the best inorganic white pigment ever produced, is widely used in many fields. In recent years, with the rapid development of my country's construction and coating industries and various materials, the demand for various types of titanium dioxide is increasing day by day, but the serious environmental pollution problems such as waste water, waste gas, and waste residues in the production process of titanium dioxide have been difficult to solve. And the consumption of titanium products such as titanium dioxide has led to an increasing shortage of titanium resources. All these factors have led to an increase in the production...
