Methods to improve adhesion of rubber products during vulcanization process

In the production process of rubber products, vulcanization is a key step. Improving the adhesion between rubber and substrate not only improves the quality of the product, but also significantly extends its service life.

Adjust vulcanization conditions

During the vulcanization process, the adhesion of rubber products can be effectively improved by adjusting conditions such as temperature, pressure, and time. Experimental data shows that the temperature is optimal in the range of 150-170 degrees Celsius, the pressure is controlled at 1-2 MPa, and the vulcanization time is 20-30 minutes.

Use optimized vulcanization formulas

Choosing the right vulcanization formula is also key. Adding appropriate amounts of ingredients such as accelerators, cross-linking agents and fillers to the formula can enhance adhesion. For example, a formula that adds 5% accelerator A and 2% filler B has the best effect.

Add surface treatment steps

Proper treatment of the rubber surface before vulcanization, such as sanding, cleaning and priming, can significantly improve adhesion. An actual application case shows that by sanding and applying primer, the adhesion of rubber products is increased by 30%.

Through the above methods, manufacturers and engineers can greatly improve the adhesion of rubber products, thereby improving product quality and meeting market demand. We sincerely invite experts and researchers in related fields to have in-depth discussions and share more experiences and insights.
