Abstract

The invention discloses a cationic soap-free starch based styrene-acrylic-rosin emulsion for sizing the surface of corrugated paper. The emulsion has wide raw material source since home-made cationicstyrene-acrylic emulsion and natural rosin are used as raw materials; starch and rosin are added into the raw materials, cost for the styrene-acrylic emulsion can be greatly reduced, and the problemsof high production cost, and environmental pollution and the like of existing styrene-acrylic emulsion can be solved; the cationic emulsion can be independently adsorbed to the surface of fibers carrying negative charges, sizing can be performed under a near-neutral condition by adding a small amount of alumina or not adding alumina. The cationic soap-free starch based styrene-acrylic-rosin emulsion accords with the concept of circular economy development, and has excellent market prospect and economic value.

Description

technical field [0001] The invention relates to a cationic non-soap starch-based styrene-acrylic-rosin emulsion for corrugated paper surface sizing. [0002] The invention belongs to a cationic soap-free starch-based styrene-acrylic-rosin emulsion product used for corrugated paper surface sizing. Solve the problems of poor water resistance and pollution of packaging cartons in the current express delivery process. Background technique [0003] At present, the surface sizing process is usually used in the paper industry, which is the process of mixing the surface sizing agent with the boiled surface sizing starch, and sizing the paper surface through a sizing machine. [0004] Styrene-acrylic emulsion surface sizing agent has good water resistance, and has good film-forming and latex film properties. It is tightly combined with paper fibers and has good surface sizing performance. However, its cost is high, and it is necessary to add additives such as aluminum sulfate in th...
