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
The invention belongs to rosin deep process technology field, relate in particular to the preparation method of the brilliant rosin of a kind of resistive connection.
Background technology
Rosin is important industrial chemicals, is widely used in the industries such as soap, papermaking, paint, rubber.But because rosin has crystallization tendency, CRYSTALLIZATION OF ROSIN can make transparency, solubleness reduce, CRYSTALLIZATION OF ROSIN fusing point can be up to 110 DEG C~135 DEG C, and rosin also has the trend of recrystallize in solvent, reduce use value.Now, need to carry out corresponding processing to rosin and prevent to the greatest extent its crystallization.
Generally, the method that prevents CRYSTALLIZATION OF ROSIN be generally adopt add forced ventilation cooling, prevent that moisture from entering, avoiding the modes such as vibrations, but these method degree-of-difficulty factors are large, are difficult to the control that reaches stable, so rosin still there will be crystallization in various degree.
Summary of the invention
The technical problem that the present invention solves is to provide a kind of preparation method of the brilliant rosin of resistive connection with anti-crystallization, the method can solve and existingly prevent that the method degree-of-difficulty factor of CRYSTALLIZATION OF ROSIN is large, the problem that is difficult to reach stable control and still there will be crystallization in various degree.
In order to solve the problems of the technologies described above, the technical solution adopted in the present invention is:
The preparation method of the brilliant rosin of a kind of resistive connection is:
First the rosin of 0.8 weight part~0.1 weight part is put into reactor, heating melts, and then, to the Sodium phosphate dibasic that adds 0.0001 weight part~0.0005 weight part in described reactor, at the temperature of 185 DEG C~215 DEG C, stirs; When described Sodium phosphate dibasic dissolves when complete, stop stirring, leave standstill after 10 minutes~15 minutes discharging.
Owing to adopting technique scheme, the beneficial effect that the present invention obtains is:
The present invention adopts and on the aufwuchsplate of rosin crystal, generates one deck molecule different from its lattice arrangement, thereby destroy the growth of follow-up lattice on rosin crystal face, hinder crystal growth, thereby effectively stop and delay CRYSTALLIZATION OF ROSIN, make rosin in the time solidifying, be unlikely formation crystal, thereby reach the object of resistive connection crystalline substance.
