Abstract
The invention provides a deinking agent adopting drainage oil as a main raw material and a preparation method of the deinking agent. The preparation method of the deinking agent comprises the steps such as pretreatment, saponification, mixing and forming of the drainage oil. The post-processed drainage oil is mixed and dissolved with stearic acid, oleic acid and hexadecanoic acid to perform saponification reaction, then penetrating agent or emulsifier and inorganic mineral clay are added, and the mixture is extruded, formed and cooled to obtain the deinkinge agent. Due to the adoption of the method, the environmental pollution caused by the drainage oil can be reduced, and harm on the health of people caused by secondary eating of the drainage oil can be avoided; and at the same time, the method is low in production cost, the product has a good deinking effect, has an obvious effect on the secondary fibers with high ink content such as old news paper (ONP), old books and old magazines, and has a good application prospect.
Description
Technical field
The present invention relates to the papermaking chemical product deinking agent, particularly relating to the sewer oil is deinking agent of main raw material and preparation method thereof.
Background technology
Sewer oil, all kinds of poor quality oils that general reference exists in life like the edible oil that reclaims, the frying oil that uses repeatedly etc., also are called " discarded edible oil " perhaps " hogwash fat ".
The basic chemical structure of edible oil is a triglyceride level, has connected three fatty acid molecules on a glycerol molecule that is:; Lipid acid is divided into sfas and unsaturated fatty acids.Contain undersaturated chemical bond in the unsaturated fatty acids, change easily, especially by airborne dioxygen oxidation.Temperature is high more, and this oxidation rate is just high more.Grease all can be heated to very high temperature in cooking process, so the edible oil of frying is long duration of service, the content of oxidation products will increase greatly.Oxidation products can make oil produce niff, and main is that oxidation products can have adverse influence to person health.On the other hand, the depleted edible oil is normally poured swill into, and nutriment is sufficient in the swill, and bacterium breeds in a large number, and the material majority that bacterial metabolism produces is to toxic elements in human body, harmful.Therefore, sewer oil can not remake into the edible oil secondary edible.
From the angle of chemistry, though lipid acid is oxidized, the substruction of sewer oil still is triglyceride level.Triglyceride level is the important source material of making the soap class.As everyone knows, the fatty acid soaps class is good printing ink supplementary set agent in the secondary stock deinking process, and sewer oil through suitably handling after saponification, is added other tensio-active agents and forming agent, can compositely obtain deinking agent.
Summary of the invention
Handle and the deficiency of using to sewer oil, for reducing the harm of sewer oil to environment and human body, reduce the production cost of deinking agent simultaneously, it is deinking agent of main raw material and preparation method thereof that the present invention provides with the sewer oil.
This preparation method comprises pre-treatment, saponification, composite, the moulding of sewer oil.Pretreated sewer oil mixes the back fusion with Triple Pressed Stearic Acid, oleic acid, palmitinic acid, carry out saponification reaction, adds permeate agent or emulsifying agent, inorganic mineral clay then, obtains deinking agent after extrusion moulding, the cooling.
Provided by the invention is the deinking agent and the preparation thereof of main raw material with the sewer oil, specifically is achieved through following technical scheme:
(1) with sewer oil and heating while stirring after water mixes, and then add inorganic salt and fully stir and leave standstill after making the inorganic salt dissolving, the upper strata oil reservoir is got in the profit layering, is rough sewer oil;
(2) with adding gac again after the rough sewer oil heating, fully carry out suction filtration behind the stirring and dissolving gac, behind the removal solid matter, last filtrating is refining sewer oil;
(3) will make with extra care sewer oil, Triple Pressed Stearic Acid, oleic acid, the fusion of palmitinic acid mixing post-heating; Obtain the mixture of sewer oil and lipid acid, add entry then, splash into inorganic alkali solution again and carry out saponification reaction; Rate of addition is 5ml/min～20ml/min; Dropwise the back and be incubated 0.5h～1h down for 60 ℃～90 ℃, add permeate agent or emulsifying agent, inorganic mineral clay then, stir in temperature;
(4) product that step (3) is obtained is transferred in the former while hot, and extrusion moulding, cut-out obtain neat soap shape deinking agent after the cooling.
Further, the heating of step (1), stirring are under 50 ℃～80 ℃, to carry out.
Further, the heating of step (2), stirring are under 80 ℃～100 ℃ conditions, to carry out.
As preferably, the mass ratio of said sewer oil of step (1) and water is 1: 0.5～1; Said inorganic salt are NaCl, CaCl
2, Na
2SO
4The inorganic salt consumption is 5%～10% of a sewer oil quality.
As preferably, the said amount of activated of step (2) is 0.5～5% of a rough sewer oil quality.
The said refining sewer oil of step (3), Triple Pressed Stearic Acid, oleic acid, palmitinic acid mass ratio are 10: 0.5～1: 1～2: 2～3; The quality that adds entry be sewer oil and lipid acid mixture quality 30%～60%.
The said inorganic alkali solution of step (3) is NaOH solution, KOH solution or Na
2CO
3Solution.The inorganic alkali solution consumption be sewer oil and lipid acid mixture quality 15%～20%.
The said permeate agent of step (3) is the fatty alcohol polyethenoxy ether class material, like AEO-9; Emulsifying agent is a TX10 class material, like OP-10; Said permeate agent or emulsifying agent consumption be sewer oil and lipid acid mixture quality 5%～15%.
The said inorganic mineral clay of step (3) is zeyssatite, wilkinite or polygorskite; Inorganic mineral clay consumption be sewer oil and lipid acid mixture quality 20%～40%.
Compared with prior art, the present invention has the following advantages:
What 1, the present invention was prepared is the deinking agent of main raw material with the sewer oil, can be used for useless book paper, the old newsprint higher secondary stock deinking process of printing ink content such as (ONP), remarkable to ink detachment and removal effect; Use deinking agent provided by the invention and carry out finding after the secondary stock deinking, whiteness increases 7%ISO～10%ISO after the flotation, and further the whiteness increment of washing back reaches 9%ISO～10%ISO; Flotation residual ink clearance is all more than 50%, and washing back residual ink clearance can reach 60%～70%.
2, the preparation method of deinking agent provided by the invention is a main raw material with the sewer oil, has reduced the harm of sewer oil to environment and human body, has reduced the production cost of deinking agent; Preparation technology is simple simultaneously, and production efficiency is high.
3, the present invention provides concrete direction for the recycling of sewer oil, can also create certain economic benefits simultaneously.
