Application of modified asphalt in graphite products.
1. Introduction to modified asphalt.
Modified asphalt is a kind of asphalt obtained by high-temperature cracking and recombination, which has the characteristics of high softening point, low penetration, low viscosity and so on. Compared with ordinary asphalt, modified asphalt has better high temperature resistance, oxidation resistance and stability, so it has a wide range of application prospects in some fields. 
2. Introduction to graphite products.
Graphite products are a new type of material obtained by processing and processing with natural graphite as the main raw material. Graphite products have excellent electrical conductivity, thermal conductivity, high temperature resistance, corrosion resistance and chemical stability, so they are widely used in metallurgy, petrochemical, aerospace and other industries.
3. Application of modified asphalt in graphite products.
Modified asphalt is mainly used as a binder and impregnating agent in graphite products, which can significantly improve the oxidation resistance, high temperature resistance and mechanical strength of graphite products. In the preparation of graphite products, the modified asphalt is mixed with other raw materials, and after high-temperature melting, impregnation, curing and other processes, a new type of graphite product with excellent performance is finally obtained.
Fourth, application examples.
The following is an example of the preparation of a graphite electrode in which modified bitumen is used as a binder:
1.Raw material preparation: Mix natural graphite, modified asphalt, filler and other raw materials in a certain proportion.
2.High-temperature melting: The evenly mixed raw materials are placed in a melting furnace and melted into a flowing liquid at high temperatures.
3.Impregnation treatment: The molten liquid is poured into the mold and put into the graphite block for impregnation treatment, so that the liquid is evenly attached to the surface of the graphite block.
4.Curing molding: After impregnation, the graphite block is placed in the curing oven for heat treatment, so that the liquid gradually solidifies the graphite electrode. 
5.Post-processing: The surface treatment and processing of the formed graphite electrode are carried out to obtain the final graphite electrode product.
Fifth, the application effect.
By adding modified asphalt as a binder and impregnation agent to graphite products, the following effects can be obtained:
1.Improve the oxidation resistance and high temperature resistance of graphite products, so that graphite products can work stably for a long time in a high-temperature environment.
2.Improve the mechanical strength and conductivity of graphite products, so that graphite products can better adapt to various complex working environments.
3.Reduce the production cost of graphite products, improve production efficiency, and bring more economic benefits to the production of graphite products. 
VI. Conclusions. To sum up, modified asphalt has a good application prospect and a wide range of application fields in graphite products. By adding modified asphalt as a binder and impregnation agent, the performance of graphite products can be significantly improved, the production cost can be reduced, and the production efficiency can be improved. In the future, with the continuous improvement and perfection of modified asphalt preparation technology, its application in graphite products will be more extensive and deeper.
