Problems solved by technology

However, TMP has two major defects: (1) poor weather resistance, easy to turn yellow due to high temperature during use: (2) strong hygroscopicity, the fluidity of the treated titanium dioxide is poor, and the particles are extruded. It is easy to agglomerate, which makes it inconvenient for customers to add when using

Abstract

The invention discloses a coating treatment agent capable of improving weather resistance of titanium dioxide and a preparation method thereof, and relates to the technical field of organic materials. When the coating treating agent capable of improving the weather resistance of the titanium dioxide is prepared, 2-fluoro-5-hydroxyisophthalic acid and 2-fluoro-5-hydroxym-phenylenediamine are polymerized and then react with hydroxymethyl trimethoxy silane to prepare modified polybenzamide, ferric nitrate and terephthalic acid react to prepare a metal organic framework, and the metal organic framework is added into the modified polybenzamide to prepare the coating treating agent capable of improving the weather resistance of the titanium dioxide. The preparation method comprises the following steps: carbonizing a metal organic framework, oxidizing, reacting with monochloroacetic acid to prepare modified carbon quantum dots, reacting modified polybenzamide with the modified carbon quantum dots, and uniformly mixing with acetone to prepare the coating treating agent capable of improving the weather resistance of titanium dioxide. After titanium dioxide is treated by the coating treating agent capable of improving the weather resistance of the titanium dioxide, the titanium dioxide has excellent weather resistance and flowability.

Description

technical field [0001] The invention relates to the technical field of organic materials, in particular to a coating treatment agent capable of improving the weather resistance of titanium dioxide and a preparation method thereof. Background technique [0002] Titanium dioxide, commonly known as titanium dioxide. It is an important chemical raw material and is closely related to the national economy. Worldwide, 90% of ilmenite is used in the production of titanium dioxide. my country is extremely rich in titanium resources, and its reserves account for 25% of the world's total titanium ore resources. It is the country with the richest titanium resources in the world, which is very conducive to the development of my country's titanium dioxide industry. Due to the lattice defects of titanium dioxide itself, there are many photoactivation points on its surface. When absorbing energy from ultraviolet rays, the oxygen atoms on the titanium dioxide lattice will lose two electron...
