Paper papermaking surface sizing agent and made by coating the sizing

摘要

The invention aims to provide a surface gluing agent for paper making. The surface gluing agent for paper making has excellent mechanical stability relative to a high-shear-force coating method (through gate rollers or gluing pressing, etc.) and has little foaming during a coating process. Meanwhile, the gluing effects are good. The surface gluing agent for paper making contains aqueous polymer emulsion which is acquired by using specific starch, unsaturated monomer compounds with specific compositions, specific polymerization initiators and using the starch with a certain amount for emulsification and polymerization.
