Description
Technical field
The present invention relates to the application fields of regenerated paper pulp, and in particular to a kind of neutral flux type for Mixed Office WasteMOW
Deinking agent and preparation method thereof.
Background technology
Mixed Office WasteMOW (MOW) has become one of four major class waste paper, wherein electro-photographic paper, laser stamping paper occupation rate
More than 90% ratio.Mixed Office WasteMOW is a kind of contactless job lot paper, and ink used is all by styrene and acrylic acid
The thermoplastic resin and color pigment of esters form, such as polyethylene, polystyrene, acrylic resin and carbon black, have water not
Dissolubility and saponification is not played to alkali, can not make the spies such as this kind of ink adhesive saponification using conventional alkaline de-inking method
Point.Mixed Office WasteMOW regenerated paper pulp long fiber content is more, and original whiteness is higher, and quality is good, and price is relatively low, is a kind of excellent
Fibre resources.As deinking handle it is bad, can only be used for produce toilet paper, wrapping paper and cardboard, affect deinking office waste paper
The high-quality application of slurry, causes the wasting of resources.
Research and application achievements show both at home and abroad：It can energy saving 40% left side with the slurrying of waste paper pulp-making ratio grass fiber
It is right；Digesting technoloy can be saved with de inked pulp, BOD the and CODCr contents in deinking wastewater are relatively low, reduce deinking and give up
The processing cost of water, reduces ambient pollution burden.
In the prior art, Chinese patent literature CN101012344 A disclose a kind of compound deinking of Mixed Office WasteMOW
Agent and preparation method thereof；Chinese patent literature CN102010630 A disclose a kind of deinking agent composition；Chinese patent literature
CN105062190 A disclose a kind of waste paper pulp-making deinking agent and preparation method thereof；Chinese patent literature CN106590140 A are public
A kind of preparation method of environmentally protective high efficient ink-removing agent is opened.These deinking agents only consider deinking efficiency aspect, use life
The substance of object degradation property difference, is not easy to be handled after use, forms long-term residual in the environment, affect ecological environment；Or
Substance containing the biological degradabilities such as alkyl phenol polyoxyethylene ether class difference does not meet contemporary environmentally protective requirement；Although or green
Colour circle guarantor's biological degradability is good, but deinking efficiency is general, reduces the quality of Deinking Pulp.The Wang Shaoguang of South China Science ＆ Engineering University,
Yi Zhiwei, Zhao Yulin, the Miao Qingxian of Shandong Light Ind College, Li Weiqi of Southern Yangtze University et al. is about deinking of MOW
Research report all gives representative opinions and suggestions, but is concentrated mainly in alkaline agent and resin emulsion paint ink scavenger, and
It is few to neutral solvent type deinking agent application report.Neutral flux deinking is a kind of new chemical method Deinking Technology, is being not added with
Deinking is carried out in the case of the conventional alkaline deinkings medicament such as hydrogen oxide and sodium metasilicate.It is de- that it substantially overcomes conventional alkaline
The disadvantage of ink, also has good effect for the Mixed Office WasteMOW of more difficult deinking.Therefore, the neutrality of novel high-efficiency environment friendly is researched and developed
Solvent deinking agent solves the problems, such as deinking of MOW process, has weight to the sustainable development of paper industry
Want meaning.
