Embodiment 1

[0019] This rosin glyceride comprises the following preparation steps:

[0020] A, raw material 100kg rosin is evacuated and decompressed and distilled to obtain refined rosin;

[0021] B. Under stirring, put the refined rosin prepared in step A into the reactor, and add 0.0001 kg of tetraethyl orthosilicate, 5 kg of hydrogen peroxide, 0.001 kg of cetyltrimethylammonium bromide, glycerin 15kg and 0.02kg of sodium acetate, then stirred at a constant temperature and reacted for 1 hour under the pressure below the triple point;

[0022] C. Put the material obtained in step B into a distillation tower, and carry out distillation at a pressure of 0 MPa and a temperature of 200° C. to obtain rosin glycerides.

[0023] The Garner color number of the rosin glyceride prepared in this embodiment is No. 1, and the purity is as high as 99%.

Embodiment 2

[0025] This rosin glyceride comprises the following preparation steps:

[0026] A, raw material 100kg rosin is evacuated and decompressed and distilled to obtain refined rosin;

[0027] B. Under stirring, put the refined rosin obtained in step A into the reactor, and add tetraethyl orthosilicate 0.00016kg, hydrogen peroxide 6kg, cetyltrimethylammonium bromide 0.0015kg, glycerin 25kg and sodium acetate 0.017kg, then stirred at constant temperature and reacted for 2 hours under the pressure below the triple point;

[0028] C. Put the material obtained in step B into a distillation tower, and carry out distillation under the conditions of a pressure of -0.1 MPa and a temperature of 180° C. to obtain rosin glycerides.

[0029] The Garner color number of the rosin glyceride prepared in this embodiment is No. 2, and the purity is as high as 99.1%.

Embodiment 3

[0031] This rosin glyceride comprises the following preparation steps:

[0032] A, raw material 100kg rosin is evacuated and decompressed and distilled to obtain refined rosin;

[0033] B. Under stirring, put the refined rosin obtained in step A into the reactor, and add 0.0002 kg tetraethyl orthosilicate, 8 kg hydrogen peroxide, 0.002 kg cetyltrimethylammonium bromide, glycerin 20kg and sodium acetate 0.01kg, then stirred at constant temperature and reacted for 4 hours under the pressure below the triple point;

[0034] C. Put the material obtained in step B into a distillation tower, and carry out distillation at a pressure of -0.005 MPa and a temperature of 200° C. to obtain rosin glycerides.

[0035] The Ghana color number of the rosin glyceride prepared in this embodiment is No. 1, and the purity is as high as 99.5%.

Abstract

The invention discloses a method for preparing rosin glycerin ester and belongs to the technical field of rosin deep processing.The rosin glycerin ester is prepared from, by weight, 100 parts of rosin, 0.0001-0.0002 part of tetraethyl orthosilicate, 5-8 parts of hydrogen peroxide, 0.001-0.002 part of cetyl trimethyl ammonium bromide, 15-25 parts of glycerin and 0.01-0.02 part of sodium acetate.The method comprises the steps that rosin is refined, tetraethyl orthosilicate, hydroquinone, glycerin and sodium acetate are added, and then stirring and reacting are carried out at constant temperature and the pressure below the triple point for 2-4 hours; anthraquinone and 4,4'-sulfo-di(6-tert-butyl-3-methylphenol) are added, and then distillation is carried out at the pressure ranging from -0.1 MPa to 0 and the temperature ranging from 180 DEG C to 200 DEG C.The prepared rosin glycerin ester product has the advantages of being high in purity and light in color.

Description

technical field [0001] The invention belongs to the technical field of rosin deep processing, and in particular relates to a method for preparing rosin glyceride. Background technique [0002] Rosin glyceride is an irregular transparent block, flake or granular solid, which has good oxidation resistance and thermal stability, aging resistance, and good compatibility with polymer materials (NR, CR, SBR, SIS, EVA, etc.) , Good initial adhesion, can be used in yellow glue to improve initial adhesion, and can also be used as hot-melt pressure-sensitive adhesive, oil-soluble pressure-sensitive adhesive, self-adhesive, laminating adhesive, EVA hot-melt adhesive, polyamide hot-melt adhesive Tackifying resins for melt adhesives, sealants, varnishes, bookbinding adhesives, pipe adhesives, laminating adhesives, decorative adhesives, label adhesives, tape adhesives, etc. [0003] The traditional preparation method of rosin glyceride is that rosin or light-colored rosin is modified and...
