Abstract

The invention discloses a modified nanometer zinc oxide. The nanometer zinc oxide is activated, and then a coupling reagent is used for modifying the surface of the activated nanometer zinc oxide and the nanometer zinc oxide is covered by bismuth oxide. According to the invention, after the nanometer zinc oxide is modified, the nanometer zinc oxide used in the coating can obviously promote the hardness and adhesive force of the coating film.

Description

technical field [0001] The invention belongs to the technical field of inorganic materials, and in particular relates to a modified nanometer zinc oxide. Background technique [0002] Zinc oxide (ZnO), commonly known as zinc white, is an oxide of zinc. Insoluble in water, soluble in acid and strong alkali. Zinc oxide is a commonly used chemical additive, widely used in the production of plastics, silicate products, synthetic rubber, lubricants, paint coatings, ointments, adhesives, food, batteries, flame retardants and other products. Zinc oxide has a large energy band gap and exciton binding energy, high transparency, and excellent room temperature light-emitting performance. It is used in liquid crystal displays, thin-film transistors, and light-emitting diodes in the semiconductor field. [0003] In addition, microparticles of zinc oxide, as a nanomaterial, have also begun to play a role in related fields. Nano-zinc oxide is a multifunctional new inorganic material, an...
