Abstract
The invention discloses a preparation method of a printing ink thickening agent. The method comprises the following steps: (1) mixing 1 part by mass of aluminum isopropoxide and 0.7 part by mass of 2-ethylhexanoic acid-1-methylethyl ester, heating to a temperature of 140 DEG C, stirring for two hours; (2) dropwise adding 3 to 6 parts by mass of 2-ethylhexoic acid within 35 minutes to carry out replacement reactions; (3) after the replacement reactions, heating to a temperature of 200 DEG C, adding 3 parts by mass of alcohol water solution to carry out hydrolysis reactions; (4) after the hydrolysis reactions, adding 0.3 part by mass of sodium pyrophosphate, 0.2 part by mass of lignosulfonate, and 1 part by mass of mineral oil, rapidly cooling; (5) filtering when the system is cooled to a temperature of 40 DEG C to remove the insoluble substances in the reaction system so as to obtain the printing ink thickening agent. The printing ink thickening agent prepared by the method provided by the invention has the advantages of prominent thickening effect, environment-friendliness, no pollution, and no generation of alcoholic organic substances during the using process.
Description
Technical field
The present invention relates to the preparation method of ink thickening material.
Background technology
Thickening material is very important auxiliary agent during flexographic ink is produced, and is the key component that ink is manufactured binder, improves the rheological of ink by changing the viscosity of binder, and then improves the ability that ink adapts to high speed printing.The thickening material that at present flexographic ink is used is generally organo-aluminium compound, in binder preparation process, add, under certain temperature condition with wherein resin, vegetables oil in hydroxyl or carboxyl generation crosslinking reaction, thereby increase viscosity.But existing thickening material in use needs to dilute in advance with solvent, and can not at high temperature carry out, system temperature need to be down to 150 ℃ adds thickening material to be uniformly dispersed below, and then be warming up to more than 170 ℃, otherwise directly add membership in the time of 170 ℃, to produce local thickening excessive, and silly line particle affects ink performance.Produce and consuming timely waste energy again, in addition, the alcohol type organic producing in thickening reaction process pollutes the environment.
Summary of the invention
The object of the present invention is to provide a kind of preparation method of ink thickening material, the thickening effectiveness of its ink thickening material of preparing is obvious and environment friendly and pollution-free.
For achieving the above object, technical scheme of the present invention is the preparation method of a kind of ink thickening material of design, comprises the steps:
1) 1 mass parts aluminum isopropylate and 0.7 mass parts 2 ethyl hexanoic acid-1-methyl ethyl ester are mixed, be warming up to 140 ℃, stir 2 hours;
2) in 35 minutes, drip 3-6 mass parts 2 ethyl hexanoic acid, carry out replacement(metathesis)reaction;
3) after replacement(metathesis)reaction finishes, be warming up to 200 ℃, add the reaction that is hydrolyzed of 3 mass parts alcohol water;
4), after hydrolysis reaction finishes, add 0.3 mass parts trisodium phosphate, 0.2 mass parts sulfonated lignin, 1 mass parts mineral oil fast cooling;
5) while being cooled to 40 ℃, filter, remove by filter the insolubles in reaction system, obtain ink thickening material.
Advantage of the present invention and beneficial effect are: a kind of preparation method of ink thickening material is provided, and the thickening effectiveness of its ink thickening material of preparing is obvious and environment friendly and pollution-free, and product in use produces without alcohol type organic.
