Abstract
The invention discloses a deinking agent and a preparation method thereof. The deinking agent is prepared from the following components in parts by weight: 10-15 parts of talcum powder, 15-20 parts of anhydrous sodium sulfate, 10-15 parts of powdered soap, 8-12 parts of sodium silicate, 8-12 parts of surfactant, 37-40 parts of sodium carbonate and 0.5-1.5 parts of lauryl sodium sulfate. The deinking agent has the advantages of simple components, simple preparation method and favorable use effect, and has the effects of moistening, permeation, resin swelling, emulsification and dispersion.
Description
Technical field
The present invention relates to a kind of deinking agent, specifically a kind of deinking agent and preparation method thereof, belongs to waste paper deinking agent field.
Background technology
Waste paper is that process is used and discarded recyclable regenerative resource in productive life, along with the development of economic society, and paper usage quantity fast rise, waste paper produces in a large number.China is as the country of consumption of second-biggest-in-the-world paper and cardboard, and within 2003, paper consumption is 4,806 ten thousand tons, and the conservative estimation of waste paper yield is 1,400 ten thousand tons.
Owing to utilizing traditional papermaking of log pulping to consume a large amount of timber, destroy ecology, and cause serious pollution.Therefore, " the city papermaking " that utilizes waste paper, together with afforestation, papermaking integrated " woods slurry paper is integrated ", becomes two developing directions of modern paper industry.The effect of the municipal wastes of dissolving is also played in city papermaking simultaneously, embodies the spirit of " city produces, and dissolves in city ".There is waste paper regenerated base, supporting city in some cities, developed regions.
After ink in the printed matters such as book paper, magazine paper is removed, can obtain a kind of higher pulpwood of value for producing again.Its deinking ultimate principle is: soak paper pulp, after paper pulp fiber is loose, with deinking agent, destroy the adhesive power between waste paper fibre and ink and colored pigment, reduce the surface tension of job lot paper ink, oil content in emulsified ink, thereby the carbon ion on interleaving paper fiber or other colored ion, and form colloid with carbon ion or other colored particle, then adopt flotation and washing methods to make it depart from paper fiber.In this process, often can use deinking agent, deinking agent can make waste paper fibre separated with ink, destroys the bonding strength of ink to paper fiber, makes ink peel off and be scattered in water from fiber.
Summary of the invention
In order to address the above problem, the present invention has designed a kind of deinking agent and preparation method thereof, and this deinking agent composition is simple, and preparation method is simple, and result of use is good, has the effect of moistening, infiltration, swelling resin, emulsification, dispersion.
Technical scheme of the present invention is: a kind of deinking agent, described deinking agent is grouped into by the one-tenth of following weight part: talcum powder 10-15 part, anhydrous sodium sulphate 15-20 part, soap powder 10-15 part, water glass 8-12 part, tensio-active agent 8-12 part, sodium carbonate 37-40 part, sodium lauryl sulphate 0.5-1.5 part.
Preferably, 12 parts of talcum powder, 16 parts of anhydrous sodium sulphate, 12 parts of soap powder, 10 parts of water glass, 10 parts, tensio-active agent, 39 parts, sodium carbonate, 1 part of sodium lauryl sulphate.
The compound method of above-mentioned deinking agent is: by the above-mentioned medicine that adds said ratio to weigh of putting in order, often add a kind of medicine and all stir 5 minutes.
Acting as of each composition:
Tensio-active agent:
The effect of tensio-active agent has three kinds: wetting, infiltration, emulsion foam.These three kinds of effects may be interpreted as when adding after tensio-active agent in paper waste, because the absorption of tensio-active agent on interface has reduced the liquid-solid surface tension of waste paper and water, result water just can be sprawled at paper fiber surface, by nonwetting, become wettingly, be conducive to destroy adhesive power between ink and fiber and the cohesive force between ink; Oleophilic group one end that its emulsifying effect principle is tensio-active agent is adsorbed on ink pellet surface, and hydrophilic group one end is goed deep in water, and align and form one deck hydrophilic molecule film in ink pellet surface, oil water interfacial tension is reduced, reduce the interionic power of attracting each other of ink, prevent that ink ion from again condensing and restoring to the original state; And the hydrophilic molecule film that aligns that tensio-active agent around forms at ink is again the protective membrane that one deck is firm, prevent ink ion impact cohesion, by emulsifying effect ink, be emulsified into oil droplet, these oil droplets just leave paper fiber dispersion in water; In addition, when foaming, the foam that tensio-active agent produces has stronger adsorption to ink, and after ink is adsorbed, the surface that rises to slurries with regard to no longer condensing is conducive to remove.Tensio-active agent, except above three kinds of effects, also has and disperses and solublization.The preferred T-80 of tensio-active agent of the present invention.
Water glass:
In deinking, except making, waste paper fibre is wetting swells water glass, outside resin saponification in ink, carbon ion disperse, also to preventing that paper pulp absorption stain and stable SYNTHETIC OPTICAL WHITNER from having good effect, and the colloid of the water-soluble rear formation of water glass can effectively adsorb ink particle and is unlikely and makes it be deposited in fiber surface.
During use, select the method for flotation-washing: first the waste paper of wanting deinking is soaked after 180-240 hour at normal temperatures, add deinking chemicals, stir at normal temperatures again pulping 2 hours, make its paper fiber and ink loose separated, be attached to again on bubble, then add hydrogen peroxide 10mL, concentration of slurry 6-8%, temperature is normal temperature, finally blasts bubble flotation washing 1 hour.Both can reach good deinking efficiency with this understanding, and reduce again the consumption of the energy, for relatively large waste paper regenerated industry, its cost is low, and chemical superiority is brought into play fully in deinking process.
Wherein the inventor finds through experiment: when paper: most pronounced effects when deinking agent is 20: 1.Experimental results show that, deinking efficiency does not strengthen with the consumption of deinking agent, for excessive this behavior explains of Deinking Effect that can suppress of deinking agent, be: with the increase of deinking agent consumption, may by one deck deinking agent molecule, be surrounded by a part of color development ion, and in the hydrophobic group Surface Contact process of this layer of deinking agent and separated solid substance, arrange with together with the water chain hydrophobic group of other tensio-active agent again.This arrangement causes (1) solublization to become large, and part chromonic material is dissolved in water; (2) too much deinking agent and chromonic material are fought for the position (excessively wetting) on bubble surface mutually, thereby deinking efficiency is affected.
Beneficial effect of the present invention is: deinking agent composition is simple, and preparation method is simple, and result of use is good, has the effect of moistening, infiltration, swelling resin, emulsification, dispersion.
