Description

Technical Field

[0001] The invention relates to the technical field of polymerized rosin resin preparation, and in particular to a method for preparing light-colored and highly stable polymerized rosin resin. Background Art

[0002] Rosin resin is a light-colored, highly polymerized (dimerized) high softening point, high viscosity, and better oxidation resistance, and completely resistant to crystallization in liquid state or in solution. Rosin resin is a tricyclic diterpene compound with a melting point of 172-175°C and an optical rotation of -102° (anhydrous ethanol). Rosin resin solubility: insoluble in water, soluble in ethanol, benzene, chloroform, ether, acetone, carbon disulfide and dilute sodium hydroxide aqueous solution;

[0003] In the existing rosin resin evaporation process, after being soaked in anhydrous ethanol, it needs to be precipitated and left to stand for three to four days before filtering, which takes a long time. After precipitation and filtration, the essential oil obtained by the soaking still contains a small amount of particulate impurities. At the same time, a small amount of dust will enter during the precipitation process, so the polymerized rosin resin produced by the evaporation process is not high in purity and the preparation efficiency is low.

[0014] Preferably, a method for preparing a light-colored, high-stability polymerized rosin resin further comprises the following specific steps:

[0015] S1: The resin to be treated is mixed with anhydrous ethanol and allowed to stand for five minutes, and then introduced into the conical heating tube through the second solenoid valve. At the same time, the electric heating wire is energized to heat the resin and anhydrous ethanol inside the conical heating tube. At this time, the resin is completely dissolved in the anhydrous ethanol, and the anhydrous ethanol can completely extract the semen in the resin;

[0016] S2: by opening the electromagnetic valve 1, the resin essential oil, anhydrous ethanol and resin impurities in the conical heated tube are discharged into the feed pipe at the same time, and then fall into the top of the bottom plate through the feed pipe. At this time, the servo motor is driven to make its output shaft drive the rotating shaft to rotate, thereby driving the receiving drum fixed to it to rotate. Under the action of centrifugal force, the resin essential oil, anhydrous ethanol and resin impurities on the top of the bottom plate are discharged to the spiral channel plate through the solid discharge hole. At this time, liquids such as resin essential oil and anhydrous ethanol fall into the bottom of the inner cylinder shell through the gap between the spiral channel plate and the inner cylinder shell. At the same time, the resin impurities and the remaining small amount of liquid move upward through the guiding effect of the spiral channel plate. In the process of transporting materials, the liquid re-enters the inside of the receiving drum through the screen, and then falls into the bottom plate through the liquid guide hole on the baffle plate, and then is discharged from the solid discharge hole again and falls into the bottom of the inner cylinder shell. The remaining resin impurities are transported to the top of the receiving drum through the guiding effect of the spiral channel plate, and then fall into the solid storage area under the action of centrifugal force, and then are discharged from the solid discharge port on the side wall of the outer cylinder shell;

[0017] S3: When the resin essential oil and anhydrous ethanol completely fall into the bottom of the outer cylinder shell, the resin essential oil and anhydrous ethanol at the bottom of the outer cylinder shell are discharged into the separation tube through the liquid inlet pipe by driving the gear pump. At this time, the liquid level in the separation tube completely covers the liquid level observation tube, and boiling water is injected into the boiling water bath area at the same time, so that the liquid in the separation tube is in the boiling water bath. At this time, the resin essential oil and anhydrous ethanol in the separation tube will evaporate, and the evaporated resin essential oil and anhydrous ethanol gas will enter the square cooling shell through the separation tube;

[0018] S4: coolant is introduced into the three groups of cooling blocks through a water tank, so that the coolant circulates in the cooling grooves in the cooling blocks. At this time, the resin essential oil and the anhydrous ethanol gas are cooled and liquefied after contacting the cooling blocks. Since the boiling point of the resin essential oil is greater than that of anhydrous ethanol, the liquefied resin essential oil will flow back into the separation tube through the cooling groove wall, and the anhydrous ethanol gas will be discharged from the exhaust slit and then collected by the ethanol collection box;

[0019] S5: Since only a few sets of exhaust slits are provided on the top of the water bath shell, resistance can be provided for the overflow of resin essential oil and anhydrous ethanol gas, allowing the square cooling shell to leave the boiling water bath, providing some condensation opportunities for the resin essential oil vapor. The exhaust slits are provided so that the square cooling shell is not in a sealed state, which can increase the internal pressure of the square cooling shell to provide condensation reflux conditions for the resin essential oil, and allow the ethanol vapor to gradually dissipate from the exhaust slits. When the liquid level in the liquid level observation tube no longer changes, it means that the anhydrous ethanol in the separation tube is completely evaporated. At this time, the boiling water bath is stopped and the discharge pipe is opened, so that the resin essential oil in the separation tube can be completely discharged and collected.

[0020] The beneficial effects of the present invention are:

[0021] 1. Mix the resin to be treated with anhydrous ethanol and let it stand for five minutes, then introduce it into the conical heating tube through the electromagnetic valve 2, and at the same time energize the electric heating wire to heat the resin and anhydrous ethanol inside the conical heating tube. At this time, the resin is completely dissolved in the anhydrous ethanol, and the anhydrous ethanol can completely extract the semen in the resin. By opening the electromagnetic valve 1, the resin essential oil, anhydrous ethanol and resin impurities in the conical heating tube are discharged into the feed pipe at the same time, and then fall to the top of the bottom plate through the feed pipe. At this time, the servo motor is driven to rotate the receiving drum. Under the action of centrifugal force, the resin essential oil, anhydrous ethanol and resin impurities on the top of the bottom plate are Grease impurities are discharged onto the spiral channel plate through the solid discharge holes. At this time, resin essential oil, anhydrous ethanol and other liquids fall into the bottom of the inner cylinder shell through the gap between the spiral channel plate and the inner cylinder shell. At the same time, resin impurities and a small amount of other liquids move upward through the guidance of the spiral channel plate. During the material transportation process, the liquid re-enters the inside of the receiving drum through the screen, and then falls onto the bottom plate through the liquid guide hole on the baffle plate, and then is discharged from the solid discharge holes again and falls into the bottom of the inner cylinder shell. The remaining resin impurities are transported to the top of the receiving drum through the guidance of the spiral channel plate, and then fall into the solid storage area under the action of centrifugal force, and finally discharged from the solid discharge port on the side wall of the outer cylinder shell.

[0022] 2. When the resin essential oil and anhydrous ethanol completely fall into the bottom of the outer cylinder shell, the gear pump is driven to discharge the resin essential oil and anhydrous ethanol at the bottom of the outer cylinder shell into the inside of the separation tube through the liquid inlet pipe. At this time, the liquid level in the separation tube completely covers the liquid level observation tube. At the same time, boiling water is injected into the boiling water bath area to make the liquid in the separation tube in the boiling water bath. At this time, the resin essential oil and anhydrous ethanol in the separation tube will evaporate. The evaporated resin essential oil and anhydrous ethanol gas will enter the square cooling shell through the separation tube, and the coolant is introduced into the three groups of cooling blocks through the water tank to make the cooling The cooling liquid circulates in the cooling tank in the cooling block. At this time, the resin essential oil and the anhydrous ethanol gas will be cooled and liquefied after contacting the cooling block. Since the boiling point of the resin essential oil is greater than that of anhydrous ethanol, the liquefied resin essential oil will flow back into the separation tube through the cooling tank wall. At the same time, the anhydrous ethanol gas will be discharged from the exhaust slit and then collected by the ethanol collection box. When the liquid level in the liquid level observation tube no longer changes, it means that the anhydrous ethanol in the separation tube is completely evaporated. At this time, stop the boiling water bath and open the discharge pipe to completely discharge and collect the resin essential oil in the separation tube. BRIEF DESCRIPTION OF THE DRAWINGS

Due to the introduction of the boiling water bath, water vapor will be generated inside the boiling water bath area 172, and the water vapor will be discharged from the exhaust pipe 175. A water tank 240 is fixedly installed on the top of the exhaust fan 230. Two groups of cooling pipes 189 are fixedly installed on the top of the water tank 240.

The resin essential oil is condensed and refluxed, and the ethanol vapor can be gradually emitted from the exhaust slit 188. Specifically, the coolant is introduced into the three groups of cooling blocks 185 through the water tank 240, so that the coolant circulates in the cooling groove 186 in the cooling block 185. At this time, the resin essential oil and the anhydrous ethanol gas will be cooled and liquefied after contacting the cooling block 185. Since the boiling point of the resin essential oil is greater than that of anhydrous ethanol, the liquefied resin essential oil will flow back into the separation tube 181 through the wall of the cooling groove 186. At the same time, the anhydrous ethanol gas will be discharged from the exhaust slit 188 and then collected by the ethanol collection box 220.

[0041] The use process of the present invention is as follows: a person skilled in the art mixes the resin to be treated with anhydrous ethanol and leaves the mixture to stand for five minutes, then introduces the mixture into the conical heat receiving tube 160 through the electromagnetic valve 210, and simultaneously energizes the electric heating wire 161 to heat the resin and anhydrous ethanol inside the conical heat receiving tube 160. At this time, the resin is completely dissolved in the anhydrous ethanol, and the anhydrous ethanol can completely extract the semen in the resin. By opening the electromagnetic valve 140, the resin essential oil, anhydrous ethanol and resin impurities in the conical heat receiving tube 160 are simultaneously discharged into the feed pipe 126, and then fall into the top of the bottom plate 129 through the feed pipe 126. At this time, the servo motor 130 is driven so that its output shaft drives the rotating shaft 128 to rotate, thereby driving the rotating drum 120 fixed thereto to rotate. Under the action of centrifugal force, the top of the bottom plate 129 The resin essential oil, anhydrous ethanol and resin impurities are discharged onto the spiral channel plate 121 through the solid discharge hole 122. At this time, the resin essential oil, anhydrous ethanol and other liquids fall into the bottom of the inner cylinder shell 112 through the gap between the spiral channel plate 121 and the inner cylinder shell 112. At the same time, the resin impurities and the remaining small amount of liquid move upward through the guiding effect of the spiral channel plate 121. In the process of transporting materials, the liquid re-enters the interior of the receiving drum 120 through the screen 124, and then falls onto the bottom plate 129 through the liquid guide hole 127 on the baffle plate 125, and then is discharged from the solid discharge hole 122 again and falls into the bottom of the inner cylinder shell 112. The remaining resin impurities are transported to the top of the receiving drum 120 through the guiding effect of the spiral channel plate 121, and then fall into the solid storage area 113 under the action of centrifugal force, and then are discharged from the solid discharge port 114 on the side wall of the outer cylinder shell 111;

[0042] After the resin essential oil and anhydrous ethanol fall into the bottom of the outer tube shell 111 completely, the resin essential oil and anhydrous ethanol at the bottom of the outer tube shell 111 are discharged into the inside of the separation tube 181 through the liquid inlet pipe 182 by driving the gear pump 150. At this time, the liquid level in the separation tube 181 completely submerges the liquid level observation tube 183, and boiling water is injected into the boiling water bath area 172 at the same time, so that the liquid in the separation tube 181 is in the boiling water bath. At this time, the resin essential oil and anhydrous ethanol in the separation tube 181 will evaporate, and the evaporated resin essential oil and anhydrous ethanol gas will enter the square cooling shell 180 through the separation tube 181, and coolant is introduced into three groups of cooling blocks 185 through the water tank 240, so that the coolant is circulated in the cooling tank 186 in the cooling block 185. At this time, the resin essential oil and the anhydrous ethanol gas will be cooled and liquefied after contacting the cooling block 185. Since the boiling point of the resin essential oil is greater than that of anhydrous ethanol, the resin essential oil and the anhydrous ethanol gas will be cooled and liquefied after liquefaction. The resin essential oil will flow back into the separation tube 181 through the wall of the cooling groove 186, and the anhydrous ethanol gas will be discharged from the exhaust slit 188 and then collected by the ethanol collection box 220. Since only a few groups of exhaust slits 188 are provided on the top of the water bath shell 171, resistance can be provided for the overflow of the resin essential oil and the anhydrous ethanol gas, so that the square cooling shell 180 can leave the boiling water bath, and some condensation opportunities are provided for the resin essential oil vapor. The exhaust slits 188 are provided to make the square cooling shell 180 not in a sealed state, so that the internal pressure of the square cooling shell 180 can be increased to provide the resin essential oil condensation reflux conditions, and the ethanol vapor can be gradually emitted from the exhaust slit 188. When the liquid level in the liquid level observation tube 183 does not change, it can be indicated that the anhydrous ethanol in the separation tube 181 is completely evaporated. At this time, the boiling water bath is stopped and the discharge pipe 184 is opened, and the resin essential oil in the separation tube 181 can be completely discharged and collected.

Any person skilled in the art may modify the present invention by using the above technical solution or modify it into an equivalent technical solution. Therefore, any simple modification or equivalent replacement made according to the technical solution of the present invention shall fall within the scope of protection claimed by the present invention.
