Problem: Natural rubber compatibility challenges

Natural rubber is favored in various industrial applications due to its excellent elasticity and mechanical properties. However, in practical applications, the compatibility of different materials with natural rubber often affects its performance. In addition, incompatible material combinations may lead to reduced wear resistance, heat resistance and aging resistance of rubber products, which has an adverse effect on product quality and life.

Solution: In-depth study of the compatibility of natural rubber

In order to effectively solve the above problems, systematic compatibility research must be carried out. Through detailed experimental data and actual cases, it can be determined which materials can improve the key properties of natural rubber and which materials may negatively affect the quality of rubber.

Chemical compatibility

Chemical compatibility studies are mainly evaluated by solubility parameters, Fourier transform infrared spectroscopy (FTIR) and thermogravimetric analysis (TGA). For example, experimental data show that when rubber is mixed with certain plasticizers, its wear resistance is enhanced by 20%. However, some plasticizers can cause a decrease in anti-aging performance.

Physical compatibility

Physical compatibility examines the dispersion and mixing uniformity of materials during the mixing process. Through scanning electron microscopy (SEM) analysis, it was found that specific fillers can be evenly dispersed in the rubber matrix to improve the overall performance. However, poor dispersion will cause micro cracks on the surface of the product, affecting its wear resistance and anti-aging ability.

Actual application performance

In order to ensure the application value of the results, it is also necessary to test the performance of rubber products under actual conditions. For example, in a high temperature environment, natural rubber with a certain stabilizer added showed a 30% higher heat resistance than untreated rubber. In addition, through long-term UV aging tests, it was found that with the help of UV stabilizers, the anti-aging performance of rubber was significantly improved.

Summarize

Through detailed chemical and physical compatibility analysis combined with practical application testing, we can provide authoritative guidance for R&D and production, optimize natural rubber formulations, and improve its performance in all aspects. This can not only improve product quality, but also extend product life and enhance competitiveness.
