Recently, there have been frequent application innovations of silicone oil emulsion in the rubber industry, bringing significant changes to the industry. In the rubber processing link, silicone oil emulsion, as a processing aid, has greatly improved the process performance of rubber. A large rubber products enterprise in Guangdong added a silicone oil emulsion with a specific formula when producing rubber sealing strips. After that, the viscosity during rubber mixing decreased by 20%, and the fluidity was significantly enhanced, which greatly improved the production efficiency, with the output per unit time increasing by 15%. Moreover, in the vulcanization molding stage, silicone oil emulsion helps optimize the cross-linking structure of rubber molecules, making the dimensional accuracy of the sealing strips more stable, and the product defect rate dropped from 8% to 3%. In terms of improving product performance, silicone oil emulsion also performs excellently. A tire manufacturing enterprise in Zhejiang introduced silicone oil emulsion into tire rubber compounds. The wear resistance of the produced tires was improved by 18%. This is because the silicone oil emulsion forms a lubricating microstructure inside the rubber, reducing the frictional loss between rubber molecules and prolonging the service life of the tires. Furthermore, rubber products treated with silicone oil emulsion have better surface gloss and a more delicate touch, making them more attractive in the market. However, traditional silicone oil emulsion has problems with compatibility with some special rubbers, which can lead to uneven local performance. To solve this problem, many enterprises have carried out cooperation with universities. For example, a chemical research institute in Jiangsu, together with local rubber enterprises, developed a new type of modified silicone oil emulsion based on Pickering particles. By regulating the particle size, surface hydrophobicity and hydrophilicity, and optimizing the emulsification process, a high-stability silicone oil emulsion was prepared. This emulsion does not yellow, does not bleed oil, does not stick to the roller, will not form silicone oil spots on the fabric, and has good compatibility. It has been applied in industrialization demonstration in some enterprises, effectively improving the quality of silicone oil emulsion and promoting the rubber industry to develop in the direction of high quality. With the continuous innovation of technology, silicone oil emulsion is expected to bring more surprises to the rubber industry and help the industry continue to upgrade.
