Abstract

The invention relates to the field of sizing agents in the papermaking industry, in particular to alkenyl succinic anhydride sizing agent emulsion, which comprises white mud waste residue, alkenyl succinic anhydride and water, wherein a mass ratio of the alkenyl succinic anhydride to the water is 1:(1-4), and a mass ratio of the white mud waste residue to the alkenyl succinic anhydride is 1:(20-1,000). The preparation method comprises the following steps of: dispersing the white mud waste residue into the alkenyl succinic anhydride, adding the water, and mixing uniformly; or dispersing the white mud waste residue into the water, and uniformly mixing with the alkenyl succinic anhydride to prepare the stable oil-in-water (O / W) alkenyl succinic anhydride (ASA) emulsion. The industrial waste residue is recycled, and virtuous economic cycle is realized; the white mud serving as an emulsifier is lower in consumption compared with an inorganic nano-material serving as an emulsifier; under the condition of low consumption of the emulsifier, a good sizing effect can be achieved, so that the emulsification cost is lower; the alkenyl succinic anhydride sizing agent emulsion has the advantages of simple emulsification process and high concentration of the prepared emulsion; and after the alkenyl succinic anhydride sizing agent emulsion is diluted with water and added into a paper stock for sizing in pulp, and the sizing efficiency is high.

Description

[0001] technical field [0002] The invention relates to the field of sizing agents in the papermaking industry, in particular to an alkenyl succinic anhydride sizing agent emulsion, and also relates to a preparation method of the alkenyl succinic anhydride sizing agent emulsion. Background technique [0003] According to a report by China Industry News in 2008, the world's soda ash production capacity is mainly distributed in China, North America and Europe, accounting for 85% of the global total production capacity. By the end of 2006, China's soda ash production capacity reached 17.2 million tons, accounting for 34% of the world's total production capacity, ranking first in the world, while Europe and North America accounted for 29% and 23% respectively. About 0.3~0.6t of soda slag is discharged per 1t of soda ash produced, commonly known as "soda white mud". According to this calculation, the "white mud" produced by the soda making industry in my country is as high a...
