Description
Technical field
The present invention relates to a kind of deinking agent and preparation method thereof, specifically a kind of environmentally friendly deinking agent and its preparation side
Method.
Background technology
In recent years, due to the increasingly enhancing of Public environmental attitude and being becoming tight day for paper making raw material, waste paper utilization is in the world
In the range of receive extensive concern, usage amount increases year by year.Waste paper recycling, which has, to be saved protofibre, reduces environmental pollution, letter
Change technological process, reduce energy consumption the advantages that, there is good economic benefit and social benefit, be directly connected to environmental improvement and
The national economy problem of protection of resources.China is a developing country, and the forest reserves are seriously deficient, and straw resource also occurs
Shortage phenomenon, wastepaper as raw material is made full use of to seem more important.
Therefore, China largely uses fibers in grass class as pulping raw material of paper making, although we are long-pending in research and production
Many experiences are tired out and have achieved many achievements, but due to this kind of general scale is smaller of papermaking straw pulp factory, pollution control difficulty is very
Greatly, the environment to surrounding causes huge pollution, and the pollution control carried out with State Bureau of Environmental Protection is rectified, and oneself has suitable enterprise
Industry is forced to stop, closed.For such case, proportion of the waste paper in fibrous raw material is improved, oneself actively adopts as current paper plant
Method.Waste paper recycling have save protofibre resource, reduce environmental pollution, reduce energy consumption the advantages that, particularly at me
In the case of state's plupwood shortage of resources, fully rationally it will seem more important using wastepaper as raw material, oneself turns into China's papermaking
Industry solves a difficult important measures of fibrous raw material.
In recent years, progress of the China in terms of waste paper utilization or faster.From the beginning of the eighties till now, we are own develops
The used paper processing apparatus of domestic flotation washer, high density hydraulic pulper and correlation and serial waste paper deinking agent are produced, is made
Middle small paper mill has broken away from the predicament being forced to stop production, the paper grades produced also from low-grade paper turn to newsprint and white board etc. compared with
High-grade paper kind.But undeniable is our existing deinking technologies compared with advanced country in the world or with certain
Gap, the large-scale paper plant built successively recently, its equipment and deinking agent are mainly from external import.In this case, just more
Adding needs, we constantly summarize, and further investigate deinking technology, develop the novel wastepaper deinking equipment with practical value
And useless deinking agent.
Alternative deinking agent species is various in the market, the deinking agent such as used for washout algorithms technique, supplies
Deinking agent that floatation deinking technique uses and the deinking agent that is used for washing method, floatation mixing deinking process etc.；From de-
It can be divided into chemical deinking agent and enzymatic deinking agent etc. again in the mechanism of action of black agent.What is used at present in deinking process is de-
Black agent is generally anionic and the major class surfactant materials of nonionic two.
The deinking agent of anionic is typically based on fatty acid organic compound.Experimental study and production practices show,
The deinking agent of fatty acid has the advantages such as strong to the trapping ability of ink particle, use cost is low, but its infiltration to ink
Power, emulsibility, washing force seem insufficient, meanwhile, the dosage of such deinking agent is typically relatively more, so in Deinking Pulp production system
In easily produce the impurity containing ink scale problems, this to production be normally carried out and the quality of Deinking Pulp can all produce it is unfavorable
Influence, this problem has caused the attention of some manufacturers.Widely used deinking chemicals is mainly both at home and abroad
Sodium hydroxide, sodium metasilicate, hydrogen peroxide and some surfactants etc..But with new printing technology development and it is various not
With the appearance of quality ink, deinking becomes more and more difficult.Therefore, the compound deinking of multicomponent, more effects, low stain is developed
Agent is the research topic for having very much realistic meaning.The present invention is studied the deinking performance of a variety of surfactants, therefrom
The surfactant for filtering out excellent effect is compounded.
The content of the invention
One of technical problems to be solved by the invention are to provide a kind of environmentally friendly deinking agent, and composition is simple, and using effect is good,
With moistening, infiltration, swellable resins, emulsification, scattered effect.
