Abstract
The invention belongs to the technical field of de-inking and in particular discloses a preparation method of an efficient waste paper de-inking agent. The preparation method comprises the following steps: putting the beef tallow serving as a raw material into a reaction kettle; adding water and sodium hydroxide; performing steam heating until boiling; continuously stirring until saponification is finished to obtain transparent liquid soap; precipitating and cooling the liquid soap in the reaction kettle; after soap and water are separated, putting separated soap into an agitation tank; adding a surfactant and auxiliary materials into the agitation tank; and after evenly stirring, pelleting and drying to obtain the de-inking agent. The product disclosed by the invention has good compatibility with other chemical additives, is energy-efficient and environmentally-friendly and completely meets the waste paper de-inking requirements of Europe, America, Japan and the like; and the whiteness of the finished product paper can be improved by 2-5%, and the ink removal rate can be improved by 10-15%.
Description
(1) technical field
The invention belongs to Deinking Technology field, particularly a kind of preparation method of efficient waste paper de-inking.
(2) background technology
At present, Chinese large-sized paper plant waste paper deinking agent adopts the external product of import more, external deinking agent consumption is few, steady quality, domestic deinking agent effect is poor, and reason is that the Surfactant Industry of China is started late, and product is relatively backward, the deinking agent formula of China lacks the compatibleness theoretical direction of various tensio-active agents besides, and compatibleness is poor.
China's waste paper deinking agent composition is the earliest industrial soap hydro-oxidation sodium, adds rare, flower bulb alkali, hydrogen peroxide.On market, deinking agent composition adopts Sodium dodecylbenzene sulfonate and alcohol ethers or phenolic ether class tensio-active agent more now.At present, the deinking agent cost in China market is higher, and deinking efficiency is poor.
(3) summary of the invention
The present invention is in order to make up the deficiencies in the prior art, a kind of reasonable ratio is provided, prepared the preparation method of simple efficient waste paper de-inking.
The present invention is achieved through the following technical solutions:
A preparation method for efficient waste paper de-inking, take butter as raw material, mainly comprises the steps:
(1) butter are placed in to reactor, add water and sodium hydroxide, be steam heated to boiling, and constantly stir, until saponification is complete, obtain transparent liquid soap;
(2) liquid soaps is precipitated in reactor cooling, after the separation of soap water, isolated soap is put into stirred pot;
(3) in stirred pot, add tensio-active agent and auxiliary material, after stirring, put into tablets press granulation;
(4) particulate state soap being put into drying baker dries.
Described tensio-active agent is sulfonic acid, fatty alcohol-polyoxyethylene ether, alkylphenol polyoxyethylene, polyoxyethylene-sorbitan mono-oleate Soxylat A 25-7, ethylenediamine tetraacetic acid (EDTA) and lauric acid atactic polyether.
Described auxiliary material is sodium sulfate, carboxymethyl cellulose and stripper.
The present invention has adopted industrial soap, and added the state-of-the-art tensio-active agent of current home and overseas, through scientific appraisal, obtained the most rational proportioning of each composition, through special process exquisiteness, form, there is very strong wetting, infiltration, emulsification, dispersion, solubilising, trapping and flocculation ability, there is the destructiveness of multiple inks link agent, particularly water-based ink being had to good removal effect, is the substitute of traditional deinking agent.
In stirred pot, the weight proportion of soap, tensio-active agent and auxiliary material is soap 50 ~ 60%, sulfonic acid 4 ~ 5%, fatty alcohol-polyoxyethylene ether 2 ~ 3%, alkylphenol polyoxyethylene 1 ~ 2%, polyoxyethylene-sorbitan mono-oleate Soxylat A 25-7 1 ~ 2%, ethylenediamine tetraacetic acid (EDTA) 1%, lauric acid atactic polyether 1 ~ 2%, Sodium sulfate anhydrous.min(99) 30 ~ 40%, carboxymethyl cellulose 0.3 ~ 0.5%, stripper 0.2 ~ 0.5%.
The weight ratio of described water, sodium hydroxide and butter is 1:1:3.
Described fatty alcohol-polyoxyethylene ether is MOA-9, and alkylphenol polyoxyethylene is TX-10.
Fatty alcohol-polyoxyethylene ether MOA series MOA-9 and alkylphenol polyoxyethylene TX-10 are soluble in water, there is good emulsification, washing, wettability, can be used as important component part and the emulsifying agent of liquid washing agent, mineral oil and animal and plant grease are all had to fabulous emulsification, dispersion, wettability.
The present invention can well be applicable to the alkaline environment of pH7 ~ 11, harmless to fiber, can make the ink ion that is adsorbed in fiber surface fully expand, come off, disperse, flocculate, trap, washing, flotation or washing add flotation and remove, without the original deinking equipment of change and technique.
Product of the present invention and other auxiliary chemicals compatiblenesies are good, and the deinking requirement of Europe, the United States ,Deng state is used in energy-conserving and environment-protective completely, finished paper whiteness can improve 2 ~ 5%, ink clearance can improve 10 ~ 15%, COD index can reduce by 300 ~ 500 units, and slurry yield improves 0.5 ~ 1%.
