Rubber wet mixing technology significantly reduces product production energy consumption

recently, Hunan Zhuzhou anbaolinfeng new materials Co., Ltd. blended silica with natural latex through the wet mixing process to prepare wet mixed rubber, which significantly improved the dispersion of silica in rubber, shortened the mixing cycle by 1/3, and reduced the mixing energy consumption of rubber, which is of great significance in China, which is short of wood resources by nearly 50%

according to Mai Qianli, the general manager of the company, they took the lead in realizing the wet mixing of silica and rubber in China, that is, adding fillers such as carbon black and silica when the rubber is still in the state of latex (natural latex or synthetic latex), mixing and dispersing them fully through mixing, and then manufacturing mixed rubber through flocculation (co sedimentation). The experimental results show that the wet mixing process reduces the number of mixing sections and mixing time, significantly reduces the mixing energy consumption and cost of rubber, greatly improves the dispersion of various reinforcing fillers in rubber, reduces dust pollution, and is conducive to the realization of continuous mixing process. In addition, the wet silica compound has improved in tensile strength, tear strength, resilience and other aspects to varying degrees. The rolling resistance of the compound is reduced by nearly 30% and the constant load rolling temperature rise is reduced by 20% compared with the dry compound

mixing is the key process of rubber processing, and has always been the process with the largest energy consumption in the rubber processing process, which accounts for more than half of the energy consumption of the whole rubber processing. The difference between each batch of rubber mixed by ordinary dry method mainly includes the following: improving the purity of MoSi2; Improve the density of materials; The addition of elements with stronger affinity for Si and o has greater anisotropy, which often has a great impact on the quality of subsequent processes, and also produces a large amount of dust, which is the largest dust pollution source for rubber products manufacturers such as tires. Silica reinforcing material can improve the wet road grip of the tire and reduce the rolling resistance, but due to the poor dispersion when using the traditional dry mixing method, it has an adverse impact on many physical and mechanical properties of the compound. Therefore, the rubber industry has been exploring ways to save more energy than the existing dry mixing process according to the idea of independent innovation and breakthrough, so that the compounding agent can be better and more evenly dispersed in rubber

it is understood that the wet mixing method is not only applicable to natural rubber latex, but also to styrene butadiene latex or nitrile latex after appropriate adjustment. This process has recently won the national invention company's "leading technology patent.
