Embodiment 1

[0012] The preparation method of this anti-crystallization rosin is:

[0013] First put 0.8kg rosin into the reactor, heat and melt, then add 0.0001kg disodium hydrogen phosphate to the reactor, and stir at a temperature of 185°C; when the disodium hydrogen phosphate dissolves completely, Stop stirring, let stand for 10 minutes, discharge.

Embodiment 2

[0015] The preparation method of this anti-crystallization rosin is:

[0016] First put 0.9kg rosin into the reactor, heat and melt, then add 0.0003kg disodium hydrogen phosphate to the reactor, and stir at a temperature of 200°C; when the disodium hydrogen phosphate dissolves completely, Stop stirring, discharging, after standing for 13 minutes, discharging.

Embodiment 3

[0018] The preparation method of this anti-crystallization rosin is:

[0019] First put 0.1kg rosin in the reactor, heat and melt, then add 0.0005kg disodium hydrogen phosphate to the reactor, and stir at a temperature of 215°C; when the disodium hydrogen phosphate dissolves completely, Stop stirring, let stand for 15 minutes, discharge.

Abstract

The invention discloses a method for preparing anti-crystallization rosin, and belongs to the technical field of rosin deep processing. The method comprises the following steps: putting rosin in a reactor; heating to melt; adding disodium hydrogen phosphate, and stirring at a temperature of 185-215 DEG C; stopping stirring when the disodium hydrogen phosphate is completely dissolved; standing for 10-15 minutes; and discharging. The anti-crystallization rosin prepared by the method has a good anti-crystallization effect, and cannot be crystallized when being solidified.

Description

technical field [0001] The invention belongs to the technical field of rosin deep processing, and in particular relates to a preparation method of anti-crystallization rosin. Background technique [0002] Rosin is an important chemical raw material, widely used in soap, paper, paint, rubber and other industries. However, due to the crystallization tendency of rosin, the crystallization of rosin will reduce the transparency and solubility, and the melting point of rosin crystallization can be as high as 110°C to 135°C, and rosin also has a tendency to recrystallize in solvents, which reduces the use value. At this point, the rosin needs to be treated accordingly to prevent its crystallization. [0003] In general, methods to prevent rosin crystallization are to strengthen ventilation and cooling, prevent moisture from entering, and avoid vibration, etc., but these methods are difficult and difficult to achieve stable control, so rosin still crystallizes to varying degrees. ...
