The invention relates to the surface coating liquid for papermaking, which contains an cationic water soluble polymer (A), a water soluble aluminium compound (B) and a starch (C), wherein the cationic water soluble polymer (A) contains: hydrophobic monomer (a1), methyl) propenoic acid dialkyl aminoalkyl ester (a2) and/or dialkyl aminoalkyl (methyl) acrylamide (a3) in a proportion that (a1):[(a2)+(a3)]=15-90:85-10 by weight.
Description
Technical field
The present invention relates to a kind of surface coating liquid for papermaking of paper use and paper that uses this coating fluid to obtain manufactured.
Background technology
By coating machines such as size presser (size press), door roller coating machine (gate roll), calenders (calender), surface coating liquid for papermaking is coated to paper surface, with improve paper sizing efficiency (control paper liquid-absorbent, suppress that China ink oozes out etc.), give paper and write adaptability and printing adaptability etc.Conventionally, Cypres and papermaking paper using power reinforcing agent are mixed, further suitably mix again other additives, can prepare surface coating liquid for papermaking, wherein, described Cypres consists of the various component of polymer that show the sizing efficiency corresponding with paper type and papermaking environment etc., and described paper power reinforcing agent consists of the water-soluble polymer of the raising paper strengths such as starch, polyvinyl alcohol, polyacrylamide.
Therefore, in order to improve the sizability (giving the performance of paper sizing effect, lower same) of surface coating liquid for papermaking, be, mainly using the Cypres adding in this coating fluid as improvement object.For example, in the cation surface sizing agent that contains cationic monomer, known have the ratio of components of the monomer by the hydrophobic monomers such as phenylethylene and (methyl) alkyl acrylate and (methyl) propenoic acid dialkyl aminoalkyl ester etc. are contained to cation group to be set in particular range, thereby improve the technology (patent documentation 1) of sizability; Usining in the aqueous medium of cationic copolymerization compound as emulsifying dispersant, by hydrophobic monomer is carried out to emulsion polymerization, the hydrophobic of reinforcing copolymer, make it become emulsion-type (dispersion) simultaneously, thereby guarantee the sizability of this coating fluid and the technology of stability (patent documentation 2); And under the resinoid existence of rosin, hydrophobic monomer carries out polymerisation with the monomer that contains cation group, thus the technology (patent documentation 3) of raising sizability etc.But, by these surface coating liquid for papermaking during for the low body paper of the sizing efficiencies such as body paper such as not processing with Internal Size, and when being relatively difficult to be penetrated into these coating fluids of coating such as transfer printing mode in paper, the emulsifying agent containing in this coating fluid can not be brought into play expected sizability sometimes, only thinks that the sizing efficiency that improves gained paper by the Cypres component of polymer containing in improvement surface coating liquid for papermaking is limited.
