Description

Technical Field

[0001] The utility model relates to the technical field of high softening point resin production, in particular to a distillation device for high softening point resin production. Background Art

[0002] Terpene resin is a general term for polymers obtained by cationic polymerization using terpene compounds as raw materials. It is a type of yellow to light yellow, transparent or translucent solid. Generally, the terpene resin includes terpene resin, α-pinene resin, β-pinene resin, dipentene resin, etc.

[0003] It is very difficult to obtain high softening point resin at present. This is because only by increasing the vacuum degree can low molecules on the surface of the material be extracted, and low molecules at the bottom of the material are difficult to distill out.

[0004] As disclosed in Chinese patent CN213285708U, a distillation device for producing high softening point resin includes a distillation kettle, a steam generator, a condenser, a receiving cylinder and a vacuum unit. The distillation kettle includes a kettle body and a top cover arranged on the kettle body. The bottom of the kettle body is provided with an annular steam pipeline, and a plurality of through holes are provided on the annular steam pipeline. The steam generator is connected with the annular steam pipeline through a longitudinal steam pipeline. A low molecular weight material discharge port is provided on the top cover, and the low molecular weight material discharge port is connected with the receiving cylinder through the condenser. The receiving cylinder is also connected with a vacuum unit. The utility model introduces high temperature and high pressure steam into the annular steam pipeline, and the high temperature and high pressure steam evaporates rapidly in the distillation kettle and is discharged upward from the through hole of the annular steam pipeline. On the one hand, it replaces the stirring paddle in the traditional distillation kettle; on the other hand, it enables the low molecular weight material below the kettle to be distilled out with the high pressure steam to obtain a resin product with a high softening point.

[0005] However, the distillation device for producing high softening point resin does not directly evacuate the distillation kettle, which affects the distillation effect. In addition, when stirring in the distillation kettle, raw materials will adhere to the inner wall of the kettle, which will be troublesome to clean if not removed in time.

[0006] Therefore, we proposed a distillation device for high softening point resin production to solve the above problems. Utility Model Content
