ることのできる脱墨剤に関する。DETAILED DESCRIPTION OF THE INVENTION [Field of Industrial Application] The present invention relates to a deinking agent used when recycling used paper such as newspapers and magazines. More specifically, the present invention relates to a deinking agent capable of producing deinked pulp with high whiteness and a small number of residual ink when deinking newspapers, magazines, etc. by a rough 0-chillion method or a 70-chillion/washing mixed method.

紙資源の有効利用は重要性を増して来ておシ、更に脱墨
パルプの用途も高度利用への要請が高まって来ている。Recycling of newspapers, magazines, etc. has been practiced for a long time, but recently, the effective use of waste paper resources has become increasingly important due to the shortage of pulp resources and the soaring prices. There is also an increasing demand for advanced use of carbon fibers.

足できうるものではない。These are metal ion sequestering agents such as DTPA, NTA, and 5TPP, and conventionally known chemical substances used as deinking agents for waste paper recycling along with these are alkylbenzene sulfonates, alkyl sulfates, α-olefin sulfonates, dialkyl sulfosuccinates, Anionic surfactants such as higher fatty acid salts, higher alcohol ethylene oxide adducts, alkylphenol ethylene oxide adducts, fatty acid ethylene oxide adducts, fatty acid amide ethylene oxide adducts, polyglobylene glycol ethylene oxide adducts, ethylene in fats and oils Examples include nonionic surfactants such as oxide adducts, higher alcohol ethylene oxide propylene oxide (block or random) adducts, and amphoteric ionic surfactants such as amine oxides and alkyl betaines. It is also a known fact that the effects can be increased by using these chemical substances in combination with specific organic/inorganic builders, organic solvents, etc. However, these chemical substances and their combinations do not necessarily have a high cleavage efficiency in the flotation process, and do not necessarily satisfy the requirements for obtaining recycled paper with high whiteness and a low number of residual inks. It's not something that can be done.

、く方法とは言えない。For example, fats and their salts that have excellent ink-collecting acidity in the flotation process have a drawback that their foaming properties are very low at about 70 degrees, and the removal of coagulated and floated ink is not sufficient. ing. In addition, although the conventionally known deinking surfactants described above have sufficient ink removal properties from paper in the waste paper disintegration process and foaming properties in the 70-station process, they have weak ink collection properties, and do not form on the foam layer. This method has the disadvantage that the amount of ink present in the foam layer is small and that it is difficult to remove the ink floating in the valve suspension from the system together with the foam layer. In this way, no chemical substance has been found that has all of the properties of removing ink from paper in the waste paper disintegration process, high foaming property and high ink collection property in the flotation process, and certain chemical substances A common method is to use a formulation of However, although a deinking method using this compound has some effect, it is not necessarily a satisfactory method.
