Asphalt plays an important role in the field of chemical production raw materials, and its upstream and downstream related products are numerous. This article will detail the upstream and downstream related products of asphalt, including the main raw materials, auxiliary raw materials, by-products and derivative products. The main raw material of

1. asphalt
the main raw material of
asphalt is petroleum. After petroleum is processed by distillation, cracking and other processes, a variety of hydrocarbon mixtures with different boiling points can be obtained, including asphalt. The nature and composition of asphalt are related to the origin and nature of crude oil, so the performance of asphalt from different origins may vary.

of auxiliary raw materials for

2. asphalt In the production process, in order to make the asphalt meet specific performance indicators, it is also necessary to add some auxiliary raw materials, such as:

1. modifier: used to improve the high temperature stability of asphalt, Low temperature cracking resistance, aging resistance and other properties. Common modifiers are polymers, rubber, etc.
2. Additives: such as antioxidants, anti-stripping agents, etc., used to improve the durability and service life of asphalt.

3. asphalt by-product

asphalt production process will produce some by-products, such as:

1. oil residue: asphalt production process residue, can be used for the preparation of road construction materials.
2. Petroleum gas: combustible gas produced in the production process, which can be used for combustion to provide heat energy or as chemical raw materials.

4. asphalt derivative products

asphalt as a chemical raw material, can also be further processed derived from many other products, such as:

1. waterproof material: the use of asphalt made of waterproof membrane, waterproof coating, etc., for building waterproof engineering.
2. Road construction materials: asphalt, aggregate and mineral powder are mixed into asphalt concrete for road paving.
3. Carbon materials: Pitch can be used as raw materials for the preparation of carbon materials, such as electrodes, activated carbon, etc.

In short, there are many upstream and downstream related products of asphalt in the field of chemical production raw materials, involving a wide range of applications. Understanding these related products will help to better understand the nature and role of asphalt, as well as its important position in chemical production.
