Polyester bitumen is a polymer compound that is composed of a variety of chemical components. Among them, the main components include polyester resin, asphalt and filler. These components are mixed together in a certain proportion, and after high-temperature melting, stirring, curing and other processes, they finally form a polyester asphalt material with excellent properties.
Polyester resin is one of the most important components of polyester asphalt, it is a polymer made from polyols and acids through esterification reaction. Polyester resin has high corrosion resistance, wear resistance and weather resistance, which can effectively improve the hardness and durability of polyester asphalt.
Bitumen is another important component in polyester bitumen, which is a natural organic polymer compound composed of a variety of hydrocarbons. Asphalt has good high temperature resistance and cohesion, which can effectively improve the toughness and crack resistance of polyester asphalt.
Filler is another important component in polyester asphalt, which is usually some inorganic minerals such as silicate, carbonate, sulfate, etc. Fillers can improve the physical and chemical properties of polyester asphalt, increase its hardness and durability, and also reduce production costs.
In addition to the above three main components, some auxiliary components such as modifiers, catalysts, and antioxidants may also be added to polyester asphalt to further improve its performance and processability. In the production process of polyester asphalt, these components are mixed, melted, cured and other processes according to a certain formula and process, and finally form a polyester asphalt material with excellent performance.
In short, polyester asphalt is a high-performance pavement material, and its excellent physical and chemical properties are mainly due to the ratio and processing technology of its main components polyester resin, asphalt and filler. Understanding the main components of polyester asphalt and its role will help to better apply this material and play an important role in road construction, waterproofing engineering and other fields.
