Method for preparing nanometer high reaction interface activated zinc oxide

Abstract

A method for preparing nanometer high reaction interface activated zinc oxide takes secondary zinc powder which contains over 80 percent of zinc oxide as a primary raw material, and comprises the steps of acid dipping, restoration with zinc powder, secondary oxidation, neutralization, washing, drying, calcining, packaging and ammonium sulphate preparation. The zinc oxide has the advantages of high reaction interface, high activity, large specific surface area, easy dispersion and the like, effectively reduces the consumption of zinc by sizing materials and the contact surface of rubber, increases the utilization ratio of zinc oxide, and serves as a substitute product for ordinary 99.7% zinc oxide. More importantly, the invention can achieve the effects of improving the qualities of products, reducing the cost of products, saving a great amount of resources for the state, and reducing environmental pollution.

Description

A kind of preparation method of nanometer highly reactive interface active zinc oxide Technical field: The invention relates to a preparation method of zinc oxide, in particular to a preparation method of nanometer high-reaction interface active zinc oxide. Background technique: At present, there are many methods for producing active zinc oxide in the prior art. Usually, there are improved ammonium bicarbonate full wet method to produce high active zinc oxide, ammonium bicarbonate precipitation method, zinc ore full wet method, and ammonium water circulation complexation method to produce high active zinc oxide. Active zinc oxide, ammonia-ammonium liquid complexation method, etc., the preparation methods are as follows: (1) COIG9 / 02 This method uses smithsonite or zinc calcined sand as raw material, and uses the principle of complexation with ammonia-ammonium liquid to prepare active zinc oxide. The cost of zinc oxide produced by this process is high, does not meet the c...

Problems solved by technology

This method is complex in process and high in purity of zinc oxide. In the application, residual zinc remains in the rubber, which will pollute the environment for a long time and fail to save zinc resources.
