specific Embodiment approach
[0016] A kind of alkyd resin for printing ink, it is formulated by following component by weight ratio:
[0017]
[0018] The preparation method of alkyd resin for above-mentioned printing ink is prepared according to the following method:
[0019] (1) Put waste oil fatty acid, linseed oil fatty acid, and pentaerythritol into the reaction kettle, and carry out a heat preservation esterification reaction at 250°C-270°C. During the heat preservation esterification reaction, the resin is sampled and detected. When detecting the viscosity of the resin sample Cool down when it reaches 1-2Pa·s (25℃, 1000rpm);
[0020] (2) After the temperature of the reactor is lowered to room temperature, add isophthalic acid and xylene, then raise the temperature to 250°C-270°C, and feed nitrogen to carry out the esterification reaction of heat preservation, during the esterification reaction of heat preservation The resin is sampled and tested. When the viscosity of the resin sample is 4-6Pa·...
Embodiment 1
[0022] Embodiment 1: a kind of alkyd resin for printing ink, it is formulated by following component by weight ratio:
[0023]
[0024] The preparation method of alkyd resin for above-mentioned printing ink is prepared according to the following method:
[0025] (1) Waste oil fatty acid, linseed oil fatty acid, pentaerythritol are dropped into reaction kettle, carry out insulation esterification at 250 ℃, resin is carried out sampling detection in this insulation esterification reaction process, when the viscosity of detection resin sample reaches 1Pa. s(100rpm), cool down;
[0026] (2) When the temperature of the reactor drops to room temperature, add isophthalic acid and xylene, then raise the temperature to 250 ° C, and feed nitrogen to carry out the esterification reaction of heat preservation, and sample the resin during the esterification reaction of heat preservation For detection, when the viscosity of the detected resin sample reaches 4Pa·s, the acid value is belo...
Embodiment 2
[0027] Embodiment 2: a kind of alkyd resin for printing ink, it is formulated by following component by weight ratio:
[0028]
[0029] The preparation method of alkyd resin for above-mentioned printing ink is prepared according to the following method:
[0030] (1) Put waste oil fatty acid, linseed oil fatty acid, and pentaerythritol into the reaction kettle, carry out heat preservation esterification reaction at 260 ° C, carry out sampling detection to resin during this heat preservation esterification reaction process, when the viscosity of detection resin sample reaches 1.5Pa When s (100rpm), cool down;
[0031] (2) When the temperature of the reactor drops to room temperature, add isophthalic acid and xylene, then raise the temperature to 260 ° C, and feed nitrogen to carry out the esterification reaction of heat preservation, and sample the resin during the esterification reaction of heat preservation For detection, when the viscosity of the detected resin sample rea...
