Rubber protective wax is an additive added during rubber mixing. After the tire is formed and vulcanized, the protective wax will dissolve in the rubber and gradually move to the tire surface due to the saturation of the internal concentration of the rubber to form a protective wax layer. Mainly prevent the ozone in the air from causing damage to the tire surface.

When adding modified ingredients in rubber production, the planning of the addition method should not only ensure the expected effect of the test machine, but also pay attention to the control of production costs. For this reason, attention should be paid to the addition control technology of rubber protective wax:

1. Granular is easy to weigh and mix. To ensure uniform dispersion, it is recommended to add it in the early stage of mixing.

2. It is recommended to use it on an internal mixer. The mixing temperature of the open mixer should be higher than its melting point.

3. Tire 1-4phr, conveyor belt 2-6phr, other rubber products are determined according to different types of rubber, the conventional dosage is 10phr.

4. The temperature of the ozone laboratory is 45~50℃, and the experimental specifications are adjusted carefully.

5. The amount of rubber protective wax added is equivalent to 1% to 1.5% of the amount of rubber.

Our protective wax products and rubber compounds have rapid dispersibility, uniform and reasonable carbon number distribution, strong adaptability to temperature, balanced migration, strong airtightness and adhesion, and can form a uniform and airtight seal on the surface of rubber products. , Tough protective film to protect rubber products from aging caused by ozone and climate.

Since the performance of rubber protective wax is affected by many factors, we will continue to develop various specifications of rubber protective wax to meet the requirements of different use conditions.
