Problems solved by technology

Especially in transparent and translucent rubber, it can be used as anti-aging agent, but as a kind of rubber additive, the extensive use of zinc oxide also brings environmental pollution problems: when zinc is released into the environment, it enters streams, ocean currents or oceans Some zinc alloys can be toxic to microorganisms and aquatic organisms
However, although the method in this invention improves the dispersion and agglomeration of nano zinc oxide, in the actual application process, there are still problems of large average particle size and relatively small specific surface area, and the improvement effect is not significant enough.

Abstract

The invention relates to the field of preparation of nano zinc oxide, in particular to a preparation method of loaded nano zinc oxide. Stir and mix the inorganic powder according to a certain ratio to obtain an inorganic powder mixture for later use, disperse the zinc oxide powder in water to form a suspension, and add it to the mixed electrolyte solution formed by dissolving sodium carbonate and sodium chloride in water according to a certain ratio To obtain a zinc oxide suspension with an electrolyte solution, add the above-mentioned inorganic powder mixture to the zinc oxide suspension, stir and mix evenly to form a mixed suspension, then grind, filter, dry, and calcinate to obtain a supported zinc oxide Powder. The process of this method is easy to operate, and the obtained nano-zinc oxide is evenly loaded on the surface of the inorganic powder to form a coating structure, which maximizes the activity of the zinc oxide and achieves the purpose of reducing zinc, and is easy to realize industrial production.

Description

technical field [0001] The invention belongs to the field of preparation of nano zinc oxide, in particular to a preparation method of loaded nano zinc oxide. Background technique [0002] As a rubber inorganic active agent and vulcanization accelerator, nano-zinc oxide has the characteristics of fast vulcanization speed, wide reaction temperature range, high conversion rate into zinc sulfide, etc. It can also improve the smoothness, mechanical strength, heat resistance and anti-aging of rubber products , especially wear resistance. It is a high-quality raw material for manufacturing high-speed wear-resistant rubber, such as aircraft tires and radial tires for high-end cars. Compared with ordinary zinc oxide, it is more suitable for soft rubber products and latex products. Especially in transparent and translucent rubber, it can be used as anti-aging agent, but as a kind of rubber additive, the extensive use of zinc oxide also brings environmental pollution problems: when zi...
