Abstract

The invention relates to a biodegradable solid particle emulsifier and a papermaking sizing agent, belonging to the technical field of papermaking sizing agents and related industrial emulsification. The biodegradable solid particle emulsifier (hereinafter referred to as "CPs") of the present invention is prepared from cellulose nanocrystals and poly(lactic-co-glycolic acid) copolymer. The ASA emulsion prepared by using the "CPs" of the present invention is a Pickering emulsion, the droplet size is about 3.4 μm; it has high stability, and the emulsion will not produce particle aggregation, precipitation or precipitation of the water phase after being placed for 24 hours; the emulsion Good internal sizing performance of papermaking pulp can still be maintained after being placed for 3 hours; the preparation process is simple, the amount of emulsifier used is small, the cost of emulsification is low, the method is biodegradable, and has low environmental pollution.

Description

technical field

[0001] The invention relates to a biodegradable solid particle emulsifier and a papermaking sizing agent, belonging to the technical field of papermaking sizing agents and related industrial emulsification. Background technique

[0002] Water-insoluble papermaking sizing agents need to be emulsified into oil-in-water emulsions to be compatible with papermaking systems that use water as the medium. In recent years, ASA sizing agent has been widely used in high-grade paper and cardboard internal sizing due to its high reactivity, low sizing material cost and fast aging rate, especially for large high-speed paper machines with in-machine coating. . However, ASA is a highly reactive paper-making neutral sizing agent, and its hydrolysis speed is very fast. After its emulsion is stored at room temperature for more than 1 hour, the sizing effect will decrease, and the hydrolyzate will cause obstacles to papermaking and reduce sizing efficiency. Therefore, when usi...
