We know, zinc oxide as a vulcanization system will be used as an auxiliary, its filling volume is higher, usually about 5, because zinc oxide ratio is serious, filling volume is large, its impact on the density of rubber material is very big. And the dynamic use of finished products such as tires, the greater the weight, the greater the heating, rolling resistance, the service life of finished products and energy consumption are adverse, especially in modern society, people have put forward a high demand for commodity safety and environmental protection. The recent well-known foreign tire analysis material marked: its zinc oxide dosage is far below the general level of the domestic, usually about 2-3 around. However, due to the backward materials in China, we could not complete this point. According to material records, yunnan institute of chemical and metallurgical industry can completely reduce the amount of externally active zinc oxide to this level, which completely fills the gap. In addition, reduce the use of the formula cost of the impact is also large, so that after reducing the use of reduced cost into a practical.

After the application of active zinc oxide with a reduction of 30%-70%, the application of active zinc oxide has little change in such aspects as strong extension function, heat generation and aging, etc., which are much better than ordinary zinc oxide. In terms of the reduction of abrasion loss, it is much better than the active zinc oxide without reduction, and much better than the general zinc oxide without reduction, the mechanism of which needs to be discussed. Dose in terms of density, the activity of zinc oxide density decreased significantly, the falling on capital and reduce all the component products, improve the function has a great help, therefore in the use of the active zinc oxide, recommend use, reducing use of general zinc oxide 30% 70% at the mercy of concrete depends on GeChang formula system, the use is not only reducing capital requirements, more should be a function of demand.

The preparation skills of active zinc oxide have been broken and several industrial manufacturers have been formed in China. However, the appearance modification skills and application skills of active zinc oxide are not thoroughly sophisticated, and the development of its application field is greatly restricted, which restricts the structure and development of the industry. Although we have made great progress in the application of reactive zinc oxide, there is still much work to be done compared with the developed application level and the potential application prospect of reactive zinc oxide. How to overcome the bottleneck of active zinc oxide treatment skills, accelerate its extensive use in various fields, become a lot of active zinc oxide manufacturers face to be dealt with.
