Abstract
The present invention discloses composite solid deinking agent and its preparation process. The composite solid deinking agent is prepared with bentonite 45-55 wt%, attapulgite 18-22 wt%, native soda 8-12 wt%, EDTA 0.8-1.2 wt%, and soap base aliphatic sodium or alkyl polyoxyethylene ether disodium sulfo succinate 18-22 wt%. The preparation process includes the steps of mixing the components, smelting at 75-85 deg.c, stirring, regulate pH value to 9-10 with NaOH or triethanolamine, stilling, drying, crushing, etc. Owing to its bentonite and attapulgite with double surface activity and the high molecular surfactant, the composite solid deinking agent has excellent effects of trapping, emulsifying and washing off ink. In addition, it has less environmental pollution.
Description
Technical field
The invention belongs to chemical technology field, relate to needed deinking agent of a kind of waste paper utilization and preparation thereof, be specially a kind of composite solid deinking agent and preparation method thereof.
Background technology
Waste paper is recycled has become China's paper and paper pulp one important materials source.China's paper in 2004 and cardboard ultimate production reach 4,580 ten thousand t, and total quantity consumed 4,932 ten thousand t increased by 18.13% and 17.62% respectively than 2003.State Statistics Bureau's data shows that its speedup reached 13.76% and 10.94% again respectively in 2005, accounted for 10% and 14% of world's total amount respectively, occupied the second in the world, was only second to the U.S..The waste paper recovery utilization rate of China is near 40% in recent years.
Compare with several technologies by timber production paper pulp, the environmental improvement expense and the production cost of recycled writing paper all will hang down.It is reported, use the recycled writing paper that 1t is made by 100% waste paper, can save 24 trees nearly.According to the Thompson report, the regenerated paper pulp energy needed after deinking and the bleaching lacks 60% than the energy of being produced kraft paper by the wood pulp of bleaching.The another one benefit of using recycled writing paper is, the expense of production, packing, energy consumption, chemical agent is low, and BOD (biochemical oxygen demand), ejecta, smell and carbon dioxide releasing amount will lack.
The key of waste paper utilization is a Deinking Technology, the existing waste paper deinking agent of China mainly biases toward the composite of small molecules tensio-active agent, formulation also mostly is liquid, the deinking agent kind is single, outmoded, the level that is equivalent to the external eighties in 20th century, the deinking equipment of domestic large-scale paper plant and deinking agent are mainly from external import.Therefore, should develop new and effective waste paper deinking agent energetically, to satisfy the demand of domestic market.
The tensio-active agent that is used for deinking now mainly contains 2 kinds of anionic and non-ionic types, and aniorfic surfactant has good detergency ability, and its foaminess is good, and foam is thin and stable; Nonionogenic tenside has good dispersion and emulsion effect, and micelle-forming concentration is lower, can obtain good deinking efficiency under lower concentration, but the foam of its generation is less, and unstable.Respectively have tangible advantage though 2 types tensio-active agent is used for deinking,, utilize more and more difficult that the real good deinking efficiency of tensio-active agent of single component become along with the appearance of different quality printing ink.Therefore, the invention provides a kind of polycomponent, many effects, oligosaprobic compound deinking agent, have the performance more excellent than traditional deinking agent.
Summary of the invention
The present invention is a raw material with the wilkinite and the attapulgite of high absorbability, and and tensio-active agent carry out compositely, make the solid dosage deinking agent, make it to be convenient to store, transportation and using.Deinking efficiency is good, low price, non-secondary pollution, energy-conservation and environmental protection.
The preparation solid deinking agent at first should be considered the selection of solid skeletal material, and when forming solid deinking agent, framework material itself preferably also has certain or stronger deinking efficiency.The present invention adopts several solid skeletal materials such as wilkinite, attapulgite and soap base sodium soap, and from aspects such as outward appearance, hardness, the soap base sodium soap is optimum as the framework material of solid deinking agent.
The system component of composite solid deinking agent of the present invention is by weight: wilkinite 45～55%, attapulgite 18～22%, bubble flower alkali (water glass) 8～12%, EDTA0.8～1.2%, soap base sodium soap or alkyl (phenol) polyoxyethylene ether sulfosuccinic acid monoester disodium salt its one or both be mixed into 18～22% arbitrarily, surplus is a water.
The preparation method of above-mentioned composite solid deinking agent is: above-mentioned system component mixes the back 75～85 ℃ of fusions, stirs fast 15～20 minutes, makes it to merge equably, regulate PH to 9～10 with NaOH or trolamine one, the back normal temperature that stirs leaves standstill, dry cooling, oven dry, pulverizing.
The present invention program has adopted copolymerization tensio-active agent (alkyl (phenol) polyoxyethylene ether sulfosuccinic acid monoester disodium salt) and modified surface promoting agent (soap base sodium soap (calcium oleate, sodium lauryl sulphate)), adds EDTA, bubble flower alkali (water glass), wilkinite, attapulgite again.It is a kind of solid deinking agent.

For the result of use of checking deinking agent of the present invention is carried out following application test:
The deinking process parameter: waste paper is mixed waste paper, pulping mass concentration 60g/L, and 60 ℃ of pulping temperature, pulping time 30min, soaking time 1h, 60 ℃ of holding temperatures are washed 3 times, are diluted to 15g/L.60 ℃ of warm water of deinking flow process → add deinking agent → add waste paper → pulping → insulation → dilution → concentrate (sieve with 65 order copper and wash altogether 3 times) → ZBT handshcet former to copy sheet → oven dry → detection.Result such as following table:
Annotate: A, B, C, D, E, F are respectively embodiment of the invention formulation product, and be blank for not adding the contrast of deinking agent.
Compound surfactant is better than the deinking efficiency that is used alone tensio-active agent.According to Ke's grace empirical rule, in oil-in-water-type (O/W) dispersion system, because the effect of nonionogenic tenside can make colloidal particle electronegative, meanwhile, some printing ink meeting adsorpting anion tensio-active agents, also make colloidal particle electronegative, like this, when negatively charged ion and nonionogenic tenside are used, all make micelle electronegative, repel each other with electricity, can form more stable dispersion system, help printing ink and fiber separation and remove.
Because wilkinite and the composite duplex surface performance that has possessed nonionic and anion surfactant of attapulgite, have good emulsifying, washing and soil removability, with the composite back of polymeric surface active agent synergy, capture better, emulsification, clean printing ink, thus ink particle separates flush away from fiber.The environmental protection advantage that the present invention has more is: use be the not chemical pollution for the second time of inorganic natural clay mineral, thereby the organic contamination composition that the absorption property of wilkinite and attapulgite can wrap up in the printing ink has reduced the pollution of discharging waste water.
