The role of national standard modified asphalt in graphite products
With the continuous progress of science and technology, graphite products have been widely used in many fields. As one of the main raw materials of graphite products, the role of national standard modified asphalt in graphite products is becoming more and more important. This article will detail the role of national standard modified asphalt in graphite products, as well as its differences from other asphalt. 
1. Introduction to the national standard modified asphalt.
The national standard modified asphalt is a kind of petroleum asphalt processed by a special process, and its performance is better than that of ordinary asphalt. Through high temperature, high pressure, catalyst and other means, the components in the national standard modified asphalt have been rearranged and combined to form a more stable structure. This stable structure makes the national standard modified asphalt have higher heat resistance, oxidation resistance and cohesion.
Second, the role of national standard modified asphalt in graphite products.
1.binders.
In the manufacturing process of graphite products, graphite powder needs to be mixed with other materials. As a binder, the national standard modified asphalt can effectively bond graphite powder together to form a complete graphite product. Its strong adhesion and good heat resistance can ensure that graphite products are not easy to crack and fall off when used for a long time in a high-temperature environment. 
2.Antioxidant.
When graphite products are used in a high-temperature environment, oxidation reactions are prone to occur, resulting in a decrease in performance. The antioxidant components in the national standard modified asphalt can effectively delay the oxidation process of graphite products and improve their service life.
3.Plasticizer.
In the manufacturing process of graphite products, adding national standard modified asphalt can play the role of plasticizer and improve the flexibility, processing performance and mechanical strength of graphite products. This makes graphite products easier to process and shape, while also improving their reliability during use. 
4.Preservative.
Due to the good chemical stability of graphite products, they can still maintain good performance in some corrosive environments. The preservative components in the national standard modified asphalt can further enhance the anti-corrosion performance of graphite products, so that they can still maintain good use effect in harsh environments.
3. The difference between national standard modified asphalt and other asphalt.
Compared with ordinary asphalt, the national standard modified asphalt has higher heat resistance, oxidation resistance and adhesion. This enables it to better meet the production requirements in the manufacturing process of graphite products and improve the performance and service life of graphite products. In addition, the national standard modified asphalt also has better environmental performance, and its production process produces fewer harmful substances, which is in line with the current development trend of green environmental protection.
IV. Conclusions. To sum up, the national standard modified asphalt plays an important role in graphite products. It acts as a binder, antioxidant, plasticizer and preservative, which can improve the performance and service life of graphite products. Compared with ordinary asphalt, the national standard modified asphalt has more superior physical and chemical properties and environmental protection properties. In the future, with the continuous progress of science and technology and the expansion of application fields, the role of national standard modified asphalt in graphite products will become more prominent. At the same time, with the continuous improvement of environmental awareness, the application prospect of national standard modified asphalt as a green and environmentally friendly petroleum product will also be broader.
