Embodiment Construction

[0016] Below in conjunction with example, the present invention is described in further detail:

[0017] A kind of preparation method of alcohol-soluble acrylic rosin resin comprises the following steps:

[0018] A. First put 210Kg of rosin into the reactor for heating, when the temperature of the rosin material reaches 150°C to 160°C, start the stirrer of the reactor, and then add 0.21Kg of 4,4`-thio Two (6-tert-butyl-3-methylphenol) reacted and continued heating;

[0019] B. When the temperature of the material in the reactor reaches 195°C to 200°C, add 15.8Kg of acrylic acid into the reactor, and seal the reactor, then react 2 at the pressure of the reactor at 0.1 MPa to 0.3 MPa Hour;

[0020] C. After the reaction described in step B is completed, the reactor is depressurized and emptied, 8.8Kg of glycerin is added, and heated to 250° C. to 255° C. for esterification for 1 hour;

[0021] D. After the reaction in step C is over, turn on the vacuum pump to evacuate the re...

Abstract

The invention discloses a preparation method of alcohol soluble acrylic rosin resin and belongs to the technical field of rosin processing. The preparation method comprises the following steps: by taking rosin as a raw material, modifying by using acrylic acid; then, carrying out esterification reaction with glycerinum to obtain the alcohol soluble acrylic rosin resin. The prepared product alcohol soluble acrylic rosin resin has excellent performances of light color, high softening point, rapid dryness and good alcohol solubility, can satisfy the using requirement of environment-friendly water-based printing ink and alcohol soluble plate printing ink and is suitable for alcohol soluble and water-based products such as water-based coatings, oil polish and the like, and use of toxic organic solvents such as methylbenzene, dimethylbenzene, ethyl acetate and the like can be avoided.

Description

technical field [0001] The invention belongs to the technical field of rosin processing, in particular to a preparation method of alcohol-soluble acrylic rosin resin. Background technique [0002] Traditional oil-based inks use organic solvents such as toluene, xylene, ethyl acetate, ethers, ketones, etc. as additives. The prepared inks contain as much as 40% to 60% of organic solvents, and they are dried by volatilization during use. , leading to high printing costs. Organic solvents such as toluene, xylene, ethyl acetate and alcohols, ethers, and ketones are generally volatile and flammable, and can easily cause fire and explosion hazards during use; in addition, because these organic solvents are It is toxic and volatile, so it will pollute the ink manufacturing and printing environment, endanger the health of workshop workers, and at the same time, the exhaust gas or waste water discharged during the ink manufacturing and printing process will also pollute the air envir...
