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. In the stirring state, put the refined rosin obtained in step A into the reaction kettle, and add 0.0001kg of tetraethyl orthosilicate, 5kg of hydroquinone, 15kg of glycerin and 0.02kg of sodium acetate in sequence, and then Under pressure, heated to 220°C, stirred at constant temperature, and reacted for 2 hours;

[0022] C. Put the material obtained in step B into the distillation tower, and put 0.0001kg of anthraquinone and 0.001kg of 4,4`-thiobis(6-tert-butyl-3-methylphenol), and then Distillation is carried out under the conditions of 0 MPa and temperature of 280°C to obtain rosin glyceride.

[0023] The softening point of the rosin glyceride prepared in this example is as high as 120° C., 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. In a stirring state, put the refined rosin obtained in step A into the reactor, and add 0.00016 kg of tetraethyl orthosilicate, 6 kg of hydroquinone, 25 kg of glycerin and 0.017 kg of sodium acetate in sequence, and then Under the pressure of MPa, heat to 200°C, stir at constant temperature, and react for 4 hours;

[0028] C. Put the material obtained in step B into the distillation tower, and put 0.00016kg of anthraquinone and 0.0015kg of 4,4`-thiobis(6-tert-butyl-3-methylphenol), and then Distillation is carried out under the conditions of 0.01MPa and 270°C to obtain rosin glyceride.

[0029] The softening point of the rosin glyceride prepared in this example is as high as 125° C., 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. In the stirring state, put the refined rosin obtained in step A into the reaction kettle, and add 0.0002kg of tetraethyl orthosilicate, 8kg of hydroquinone, 20kg of glycerin and 0.01kg of sodium acetate in sequence, and then Under the pressure of MPa, heat to 205°C, stir at constant temperature, and react for 3 hours;

[0034] C. Put the material obtained in step B into the distillation tower, and put 0.0002kg of anthraquinone and 0.002kg of 4,4`-thiobis(6-tert-butyl-3-methylphenol), and then Distillation is carried out under the conditions of 0.005MPa and 205°C to obtain rosin glyceride. .

[0035] The softening point of the rosin glyceride prepared in this example is as high as 120° C., and the purity is as high as 99.5%.

Abstract

The invention belongs to the technical field of deep processing or rosin and discloses a rosin glycerin ester production method.Rosin glycerin ester is prepared from, by weight, 100 parts of rosin, 0.0001-0.0002 part of anthraquinone, 0.0001-0.0002 part of tetraethoxysilane, 5-8 parts of hydroquinone, 0.001-0.002 part of 4,4'- thio-bis(6-tert-butyl-3-methyl phenol), 15-25 parts of glycerin and 0.01-0.02 part of sodium acetate.The rosin glycerin ester production method includes: refining the rosin, adding the tetraethoxysilane, the hydroquinone, the glycerin and the sodium acetate under the condition of stirring, and reacting under a specific pressure and at a specific temperature; adding the anthraquinone and the 4,4'- thio-bis(6-tert-butyl-3-methyl phenol), and distilling under a specific pressure and at a specific temperature.The rosin glycerin ester produced according to the method has the advantages of high softening point and high purity.

Description

technical field [0001] The invention belongs to the technical field of rosin deep processing, and in particular relates to a production method of 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...
