Abstract

The present invention belongs to the field of nanometer material producing technology. Modified nanometer and subnanometer class superfine zinc oxide powder is produced with zinc oxide in the ammonia distillation process through adding surface modifier, or superdispersing polymer, or amphoteric structure coupling agent or other modifying solvent, and using the proper modifying process specification and method. The present invention utilizes the space steric effect to control the particles size and obtain the modified superfine zinc oxide with high dispersivity and powerful functions. The modified superfine zinc oxide powder may be used widely in rubber, ceramic, textile and daily-use chemical industries.

Description

1. Technical field

[0001] Nanoscale and submicron-scale modified ultrafine zinc oxide and its preparation method disclosed by the present invention belong to the technical field of nanomaterial production, and its technical gist is to use some modified solvents to modify ultrafine zinc oxide to obtain High-performance, highly dispersed modified ultra-fine zinc oxide, and also introduced the preparation method of this modified ultra-fine zinc oxide. 2. Background technology

[0002] Ultrafine zinc oxide powder refers to the powder with a particle size of less than 1 μm, which can be widely used in industries such as rubber, ceramics, textiles, and daily chemicals. As the particle size decreases, the specific surface area gradually increases, gradually showing the active effect that conventional powders do not have, especially when the particle size is less than 100nm, that is, when nanoparticles are formed, due to the quantum size effect, surface effect and small size Effect...
