Effect Of Multidimensional Filler Network On Rubber Materials And Vulcanization Simulation Study

Natural rubber has poor thermal conductivity,which can lead to slow heat transfer,uneven temperature distribution,and long curing time during the vulcanization process of thick rubber products.This not only affects the performance and lifespan of the rubber products,but also reduces the vulcanization efficiency and increases energy consumption.By improving the thermal conductivity of the mixing rubber,the transfer of heat during the vulcanization process can be accelerated,heating time can be shortened,and vulcanization efficiency can be improved,thereby eliminating the problem of uneven vulcanization to some extent.Through the numerical simulation study of vulcanization,the influence of post-vulcanization effect on the vulcanization degree of thick rubber products is explored,the internal vulcanization of products during natural cooling is analyzed,and the vulcanization process is further optimized,which is of great guidance to the actual production.The topic of this study is natural rubber base formulation,by studying the construction of filler networks in rubber matrix with trace carbon fibers(CF),carbon nanotubes(CNT),graphene oxide(GO)and CF/CNT hybrid fillers and their effects on the performance of rubber composites,the formulation system is optimized for energysaving vulcanization on the based of the comprehensive performance of rubber composites.Through the numerical simulation of vulcanization,the effect of postvulcanization effect on the vulcanization degree of thick rubber products is analyzed,and the optimization of vulcanization process is realized to provide theoretical and technological reference for energy-saving vulcanization of thick rubber products.The main experiments in this paper are as follows:1.Establish the filler network model of different fillers in rubber matrix,explore the formation process of synergy between different particles,and analyze the effect of synergy on filler dispersion and filler network.2.Experiments were done by adding different fillers in the base formulation to observe the morphology and dispersion of fillers inside the rubber matrix,also analyze the effect of filler content on the properties of rubber composites,validate the filler network model by the observed results and the changes of properties,and select the optimal formulation system that is conducive to energy-saving vulcanization.3.The performance of the optimal formulation model and the base formulation model were compared in the numerical simulation of vulcanization,and verify the contribution of the hybrid filler network model in reducing the vulcanization time.The post-vulcanization effect is analyzed in terms of its contribution to the uniform vulcanization of thick rubber products,and the practical role of numerical simulation of vulcanization in the vulcanization process is demonstrated by optimizing the process parameters.In summary,different fillers establish different filler networks in the rubber matrix,which have different effects on the material properties and show different effects in improving the vulcanization efficiency.The CF/CNT hybrid fillers establish the most complete filler networks and have the most obvious effects in improving the vulcanization efficiency.By optimizing the process parameters through numerical simulation of vulcanization,the vulcanization time can be shortened while ensuring the product performance.The experimental results have a certain reference value for the energy-saving vulcanization of rubber products in actual production,also have a guiding significance for the determination of vulcanization time of thick products.
