preparation example Construction

[0028] The preparation method of deinking agent comprises the following steps (each component is in volume percent):

[0029] a. Mix ethanol (30%~50%) and water (20%~40%) and heat to 50~70°C, add sodium dodecylbenzenesulfonate (0.1%~1%), sodium perborate (0.1 %~1%), sodium carbonate (0.1%~1%), after stirring, the solid is completely dissolved;

[0030] b. After the solid is completely dissolved, add cyclohexanone (10%-30%) and ethylene glycol butyl ether (5%-10%), and stir with a stirrer for 30 minutes at 50-70°C at a stirring speed of 800 ~1000 rpm to make it evenly mixed;

[0031] c. Add Span-80 (2% to 5%), continue to stir, and stop stirring and heating after 30 minutes;

[0032] d. Finally, the reaction product is cooled to room temperature to obtain the deinking agent.

Abstract

The invention discloses a deinking agent and a preparation method thereof; the deinking agent comprises the components (counted in volume percentage) as follows: 10 to 30 percent of cyclohexanone, 30 to 50 percent of ethanol, 5 to 10 percent of ethylene glycol monobutyl ether, 2 to 5 percent of span-80, 0. 1 to 1 percent of sodium perborate, 0.1 to 1 percent of sodium carbonate, 0.1 to 1 percent of sodium dodecyl benzene sulfonate and water as the rest. The invention can remove the ink marks of oil ink, marker pen, spray paint and the like flexibly; besides, the deinking agent and the preparation method have the advantages of stable performance, lower cost, innocuity and no pollution to environment.

Description

technical field [0001] The invention relates to a deinking agent capable of removing ink marks, marking pens and spray paint ink marks and a preparation method thereof. Background technique [0002] The existing deinking agent is a high-tech product, which can quickly dissolve ink, marker pen, spray paint, etc., has stable quality, is non-toxic and harmless, and has no pollution to the environment. However, due to high cost, the price is not competitive. Therefore fail to popularize and use on the market. Contents of the invention [0003] The technical problem to be solved by the present invention is to provide a low-cost deinking agent capable of removing ink marks, marking pens and spray paint ink marks and a preparation method thereof. [0004] The technical scheme adopted in the present invention: a kind of deinking agent, is made up of following components (each component is in volume percentage): [0005] Cyclohexanone 10%~30% [0006] Ethanol 30%~50% [0007] E...
