Abstract

The invention relates to a deinking agent, in particular to an environment-friendly mixed waste paper deinking agent. The prior waste paper deinking agent can only deink one class of waste paper in general. The invention provides the environment-friendly mixed waste paper deinking agent with wider application range, which is characterized in that the weight percentage of every component is: 5 to 10 percent of polyoxyethylene nonyl phenyl ether, 25 to 30 percent of fatty alcohol polyoxyethylene ether sodium sulfide, 5 to 10 percent of fatty alcohol polyoxyethylene ether, 10 to 20 percent of sulfonic acid, 4 to 10 percent of ethanol and the balance being water. Compared with the prior deinking agent, the deinking agent of the invention has the advantages of wide application range, good deinking effect and the like, and is few in components and simple in method.

Description

technical field [0001] The invention relates to a deinking agent, in particular to an environment-friendly mixed waste paper deinking agent. Background technique [0002] At present, the society pays more and more attention to the environment and energy, and advocates the recycling of resources. Waste paper recycling has become the development trend of today's society, but the commonly used waste paper deinking agents can only deink one type of waste paper, and the waste paper produced now is generally office waste paper, water-based ink, etc. When waste paper and various mixed waste papers are mixed together, all kinds of waste papers should be separated and then deinked separately. However, it is very difficult to separate all kinds of waste papers. [0003] Certainly also have some novel deinking agents at present, but all are not very ideal. For example, Chinese patent application number 200710013251.3 discloses a compound deinking agent for mixed office waste paper an...
