Medium temperature bitumen is a special chemical substance, which is mainly used in the preparation of inks, adhesives, sealants and insulating materials, etc. Its composition is complex and mainly composed of the following substances:
1.Asphaltene.
Asphaltene is one of the main components in medium-temperature bitumen, it is a dark, viscous liquid with high viscosity and stability. Asphaltenes are mainly composed of elements such as carbon, hydrogen and oxygen, and their molecular structure is complex and contains a variety of functional groups, such as hydroxyl group, carbonyl group, carboxyl group and benzene ring. In the preparation of inks, adhesives and sealants, asphaltenes can thicken, stabilize and adhede.
2.Oil.
Medium-temperature asphalt contains a certain amount of oil, which is mainly composed of fatty acids and fatty acid esters. These oils act as lubricants, reducing friction between mixtures and improving their fluidity. At the same time, the oil content can also improve the flexibility and ductility of medium-temperature asphalt, making it more processable.
3.Resin.
Resin is another important ingredient in medium-temperature bitumen, which is a mixture of various aromatic compounds. The role of resin in asphalt is mainly to improve its hardness and stability, while also increasing its heat resistance and corrosion resistance. The type and content of resin have an important impact on the properties and applications of medium-temperature asphalt.
4.Additive.
In order to further improve the properties and application properties of medium-temperature bitumen, additives such as antioxidants, plasticizers, pigments and fillers are often added. These additives can improve stability, improve processability, enhance wear resistance and improve aesthetics.
To sum up, the main components of medium-temperature asphalt include asphaltenes, oils, resins and additives. The type and content of these components have a significant impact on the properties and applications of medium-temperature bitumen. By adjusting the ratio of these components, medium-temperature asphalt with different properties and uses can be prepared to meet the needs of different fields.
