Embodiment 1

[0013] The preparation method of this anti-crystallization disproportionation rosin is:

[0014] First put 0.8kg of disproportionated rosin into the reactor, heat and melt, then add 0.0001kg of trisodium phosphate into the reactor, and stir at a temperature of 210°C; when the dissolution of the trisodium phosphate is complete, stop Stir, let stand for 15 minutes, discharge.

Embodiment 2

[0016] The preparation method of this anti-crystallization disproportionation rosin is:

[0017] First put 0.9kg of disproportionated rosin into the reactor, heat and melt, then add 0.0002kg of trisodium phosphate into the reactor, and stir at a temperature of 220°C; when the trisodium phosphate dissolves completely, stop Stir, let stand for 20 minutes, discharge.

Embodiment 3

[0019] The preparation method of this anti-crystallization disproportionation rosin is:

[0020] First put 0.1kg of disproportionated rosin into the reactor, heat and melt, then add 0.0003kg of trisodium phosphate into the reactor, and stir at a temperature of 230°C; when the dissolution of the trisodium phosphate is complete, stop Stir, let stand for 25 minutes, discharge.

Abstract

The invention discloses a preparation method of anti-crystallization disproportionated rosin and belongs to the technical field of rosin deep processing. The method comprises the following steps: heating to melt disproportionated rosin, then adding trisodium phosphate and stirring at a temperature of 210-230 DEG C; and when the trisodium phosphate is fully dissolved, stopping stirring, standing for 15-25 minutes and discharging. The anti-crystallization disproportionated rosin prepared by the method disclosed by the invention has a good anti-crystallization effect, so that the rosin does not form crystals during solidification.

Description

technical field [0001] The invention belongs to the technical field of rosin deep processing, and in particular relates to a preparation method of crystallization-resistant disproportionation rosin. Background technique [0002] Disproportionated rosin is a product obtained by a disproportionation reaction in the presence of a catalyst, through the action of inorganic acid and heat to oxidize a part of the rosin and reduce the other part. Disproportionated rosin is often made into potassium soap, which is used as an emulsifier for high molecular polymerization such as styrene-butadiene rubber, neoprene rubber, nitrile rubber and its latex, ABS, etc., to improve and enhance rubber properties; it is also widely used in the manufacture of water-soluble pressure-sensitive Adhesives can also be used as ingredients, plasticizers, and binders for rubber components; as tackifiers for adhesives; they are also important raw materials for the manufacture of chewing gum, advanced paper ...
