Abstract

The invention relates to an efficient deinking agent for mixed waste paper, and mainly solves the problems of poor deinking effect and serious environmental pollution in the prior art. The efficient deinking agent for the mixed waste paper comprises the following components in parts by weight: 15-25 parts of polyoxyethylene fatty alcohol sodium sulfate, 15-25 parts of alkylphenol polyoxyethylene, 10-15 parts of Twain-80, 25-30 parts of sodium dodecyl benzene sulfonate, 10-15 parts of attapulgite, 5-10 parts of anhydrous sodium metasilicate, 5-10 parts of ethylenediamine tetraacetic acid. By adopting the technical scheme, the problems are well solved, and the efficient deinking agent can be used for waste paper recycling.

Description

technical field [0001] The invention relates to a high-efficiency deinking agent for mixed waste paper. Background technique [0002] At present, the demand for fiber raw materials in the world is increasing day by day, and the demand for energy conservation is obvious. Recycling waste paper to make paper and cardboard has attracted the attention of the paper industry at home and abroad. Waste paper recycling can not only save energy, save plant fiber raw materials, reduce product costs, but also reduce environmental pollution, so the use of waste paper is expanding worldwide. Compared with primary resources, waste paper recycling can save water by 50%, energy by 65%, COD in sewage by 40%, and solid waste by 70%. [0003] The key to waste paper recycling is deinking, that is, under the action of physics and chemistry, the ink particles are separated from the fibers. The whole process can be divided into three stages: waste paper is shredded and separated into fibers; ink pa...
