METHOD FOR IMPROVING SIZING EFFICIENCY OF ASA EMULSION EMULSIFIED BY A POLYMER EMULSIFIER

摘要

The present invention relates to a method for improving sizing efficiency of an ASA sizing agent in a paper-making process. In particular, the invention comprises: sizing a pulp slurry by using the polymer emulsifier emulsified ASA emulsion as sizing agent, and adding, as a paper-making filler, paper-making filler particles modified by a hydroxyl-containing hydrocarbon natural polymer polysaccharide compound to the pulp slurry.
