Description

technical field [0001] The invention relates to a waste paper deinking agent, in particular to a waste paper deinking agent and a preparation method thereof, belonging to the field of waste paper deinking agents. Background technique [0002] Waste paper is a recyclable resource that is discarded after being used in production and life. With the development of economy and society, the amount of paper used is rising rapidly, and a large amount of waste paper is produced. As the world's second largest consumer of paper and cardboard, China's paper consumption in 2003 was 48.06 million tons, and the waste paper recycling volume was conservatively estimated at 14 million tons. [0003] Because the traditional papermaking using logs to make pulp consumes a lot of wood, destroys ecology, and causes serious pollution. Therefore, the "urban papermaking" using waste paper has become the two major development trends of the modern papermaking industry together with the "integration of...
