Abstract

The invention relates to the field of sizing agents in the papermaking industry, in particular to an alkenyl succinic anhydride sizing agent emulsion, which contains white mud waste residue, alkenyl succinic anhydride and water, and the mass ratio of alkenyl succinic anhydride to water is 1:1~4 ; The mass ratio of white mud waste residue to alkenyl succinic anhydride is 1:20~1000. The preparation method is to disperse the white mud waste residue into alkenyl succinic anhydride, and then add water to mix evenly; or disperse white mud waste residue into water, and then mix evenly with alkenyl succinic anhydride to prepare a stable O / W type ASA emulsion . Realize the recycling of industrial waste residues, and realize a virtuous economic cycle; the amount of emulsifier used when white mud is used as an emulsifier is lower than that of inorganic nanomaterials, and it can achieve good results at a lower amount of emulsifier. sizing effect, so the cost of emulsification is lower, and it also has the advantages of simple emulsification process and high concentration of the prepared emulsion. After diluting and emulsifying with water, it is added to the paper material for in-pulp sizing, 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. [0003] Background technique [0004] 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 ...
