Zinc Oxide is the active agent of natural latex. Sometimes it is also used as a reinforcing agent and a colorant. According to the different methods of production, it can be divided into three kinds: indirect Zinc Oxide, direct method Zinc Oxide, and active Zinc Oxide. It is the most important inorganic active agent in the rubber industry. Adding glue can not only speed up the curing rate, but also improve the degree of crosslinking. It has an activation effect on thiazole, sub sulfonamide, guanidine, and autumn lamb. It is widely used in all kinds of rubber products, especially for transparent rubber products and food products. Industrial production of Zinc Oxide has 50% flow to the rubber industry. As one of the important reactions of rubber vulcanization, Zinc Oxide and stearic acid are one of the raw materials for rubber manufacturing.
The mixture of Zinc Oxide and stearic acid strengthens the hardness of the rubber. Zinc Oxide is also an important additive for automobile tires. In addition to the vulcanization, Zinc Oxide can greatly improve the thermal conductivity of the rubber, which helps the heat dissipation of the tire, and ensures the safety of the driving. Zinc Oxide additives also prevent the erosion of mould organisms or ultraviolet light on rubber.
The role of Zinc Oxide. In the rubber tire industry (Senior black and dark rubber tire, radial tire): improve the thermal conductivity, wear resistance, tear resistance, tensile strength and other indexes, and can save about 30% amount of Zinc Oxide.
The role of Zinc Oxide in rubber products:
(1) the active Zinc Oxide is mainly used as a reinforcing agent for rubber, so that the rubber has good corrosion resistance, tearing resistance, elasticity and elongation.
2. Accelerator used for rubber vulcanization process is a multifunctional rubber compounding agent, which is mainly used for vulcanizing activator and reinforcing agent of natural rubber, synthetic rubber and latex.
(3) when used as vulcanizing activator, it is evenly distributed in the rubber, and has large contact area with hydrogen sulfide. It has great opportunity for interfacial reaction. Moreover, with the catalytic activity of active Zinc Oxide products, the conversion rate of Zinc Oxide to zinc sulfide is high.
As a vulcanizing oxidizer, its function is to improve the activity of accelerant, reduce the dosage of accelerant and shorten the vulcanization cycle.
Can speed up the vulcanization, improve the thermal conductivity of the vulcanizate, and make the vulcanization more thorough.
In the rubber industry, especially the production of rubber products, Zinc Oxide is the activity of vulcanizing agent excellent.
The role of Zinc Oxide. In synthetic rubber: as activating agent, accelerator and reinforcing agent, and a coloring function. It can promote vulcanization, activation and reinforcement and anti aging effect of rubber. It can strengthen the vulcanization process and improve the tearing resistance and wear resistance of rubber products.
The role of Zinc Oxide. In natural rubber, vulcanized rubber vulcanization activator, promoting, activation and reinforcing, anti-aging effect, can strengthen the vulcanization process, improve the tear resistance and abrasion resistance of rubber products.
The role of Zinc Oxide in natural latex. The activation, promoting rubber vulcanization, activation and reinforcement, anti-aging effect, can strengthen the vulcanization process, improve the tear resistance and abrasion resistance of rubber products.
6. The role of Zinc Oxide in the white latex as coloring agents and fillers.
7. Role of Zinc Oxide in the chloroprene rubber, vulcanizing agent and increase the thermal conductivity with the agent.
8. Zinc Oxide footwear (shoes, rubber boots, rubber gloves and other protective products) in the role of (rubber shoes, boots,
Rubber gloves and other labor protection products): improve wear resistance and anti aging, prolong the service life.
90. Zinc Oxide rubber products in transparent rubber and inorganic active agent essential food.
30. Role of Zinc Oxide in a transparent and translucent rubber, vulcanizing agent.
2. Role of Zinc Oxide in transparent or colored rubber products: a carbon black traditional active agent irreplaceable role.
