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 a stirring state, put the refined rosin obtained in step A into the reactor, and add 0.0001kg of hydrogen peroxide, 5kg of cetyltrimethylammonium bromide, 15kg of glycerin and 0.02kg of cobalt acetate in turn, and then heat to 200°C, and react at constant temperature for 4 hours under ultrasonic conditions with a power of 1200 watts;

[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 at a pressure below the phase point to obtain rosin glycerides.

[0023] The Garner color number of the rosin glyceride prepared in this embodiment is No. 2, 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;

In a stirring state, put the refined rosin obtained in step A into the reactor, and add 0.00016 kg of hydrogen peroxide, 6 kg of cetyltrimethylammonium bromide, 25 kg of glycerin and 0.017 kg of cobalt acetate, and then heat to 250°C, and under the condition of ultrasonic power of 1100 watts, constant temperature reaction for 3 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 at a pressure below the phase point to obtain rosin glycerides.

[0029] The Ghana color number of the rosin glyceride prepared in this embodiment is No. 1, 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 a stirring state, put the refined rosin prepared in step A into the reactor, and add 0.0002 kg of hydrogen peroxide, 8 kg of cetyltrimethylammonium bromide, 20 kg of glycerin and 0.01 kg of cobalt acetate, and then heat to 220°C, and react at constant temperature for 1 hour under ultrasonic conditions with a power of 1100 watts;

[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 at a pressure below the phase point to obtain rosin glycerides. .

[0035] The Garner 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 producing rosin glycerin ester, and belongs to the technical field of rosin deep processing.Rosin glycerin ester is prepared from rosin, anthraquinone, hydrogen peroxide, cetyl trimethyl ammonium bromide, 4,4'-sulfobis(6-tertiary butyl-3-methylphenol), 15-12 parts of glycerin and cobaltous acetate.The method includes the steps that rosin is refined, and hydrogen peroxide, cetyl trimethyl ammonium bromide, glycerin and cobaltous acetate are added and heated to 200-250 DEG C and react for 3-4 h at the constant temperature under the ultrasonic wave of 1100-1200 W power; anthraquinone and 4,4'-sulfobis(6-tertiary butyl-3-methylphenol) are added, then distillation is conducted at the pressure below the triple point.The produced rosin glycerin ester 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 producing 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...
