Preparation method of alcohol-soluble acrylic rosin resin

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...

Problems solved by technology

[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 environment and damage the local water resource environment; and , In the process of packaging printed matter, some toxic and harmful substances of organic solvent-based ink will remain in the printed matter, causing pollution and harm, especially in packaging with strict hygienic requirements such as tobacco, alcohol, food, medicine, beverages, and children's toys. If this type of ink is used in printing, the consequences will be more serious
