Tar resin

Tar resin, as an important chemical raw material, plays an indispensable role in multiple industries. The definition and source are as follows:

1. Definition

Tar resin is an important derivative of tar, which is a high molecular weight compound extracted from organic compounds such as coal and petroleum. It is a complex mixture obtained from raw materials such as coal, wood, and petroleum through physical or chemical methods such as dry distillation, distillation, and extraction, and has excellent properties such as adhesion, heat resistance, and chemical resistance.

2. Source

According to the different sources of raw materials, tar resin can be divided into various types:
1. Coal tar resin: mainly derived from the dry distillation process of coal. During the coal dry distillation process, coal tar is produced, which can be further distilled and separated to obtain tar resin. Coal tar resin has good heat resistance and chemical resistance, and is suitable for high temperature and high pressure environments. According to statistics, each ton of coal can produce about 150-200 kilograms of coal tar.
2. Wood tar resin: derived from the dry distillation process of wood. During the dry distillation process of wood, the organic components in the wood are pyrolyzed to form wood tar, which is then processed to obtain wood tar resin. Wood tar resin has a low softening point and good biodegradability, making it suitable for environmentally friendly products.
3. Petroleum tar resin: derived from the distillation process of petroleum. In the process of petroleum processing, petroleum tar can be obtained through distillation and other techniques. Further processing of petroleum tar can yield petroleum tar resin. Petroleum tar resin has high adhesion and oil resistance, and is widely used in industries such as coatings and adhesives.
In addition, tar resins can be classified into phenolic resins, naphthol resins, lignin resins, and other types based on their processing methods and characteristics. These different types of tar resins have their own characteristics in terms of performance and application, and can be selected according to specific needs.
In summary, tar resin, as an important chemical raw material, plays an indispensable role in multiple industries. Understanding its definition and origin can help to better comprehend and apply this material.
