摘要： To effectively impart sizing performance to paper, while reducing the amounts of an internal sizing agent and aluminum sulfate, the invention provides as a papermaking additive a mixture of a cationic copolymer having a hydrophobic group whose quarterization ratio is 40% by mole or more, or an amphoteric copolymer having a hydrophobic group which has the same quarterization ratio as above, and in which the ratio of the anion equivalent to the cation equivalent is 0.1 to 90%, and a filler (a pretreated filler). The pretreated filler is one in which suitable water repellency is imparted to the filler. Hence, by adding this to pulp slurry, followed by a wet papermaking, the pretreated filler is efficiently adsorbed onto pulp fibers having anionic property, so that effective sizing performance can be imparted to the paper by using a smaller amount thereof than the internal sizing agent, while reducing the amounts of the internal sizing agent and the aluminum sulfate.
摘要翻译：为了有效地赋予纸张施胶性能，同时减少内部施胶剂和硫酸铝的量，本发明提供了具有疏水性基团的阳离子共聚物的混合物，该疏水基团的四分子化比例为40摩尔％以上，或者具有与上述相同的季铵化比例的疏水性基团，阴离子当量与阳离子当量的比例为0.1〜90％的两性共聚物和填料（预处理填料）。预处理的填料是赋予填料适当的防水性的填料。因此，通过将其添加到纸浆中，然后进行湿法造纸，将预处理的填料有效地吸附到具有阴离子性质的纸浆纤维上，从而通过使用比内部施胶剂更少量的纸赋予纸张有效的施胶性能同时减少内部施胶剂和硫酸铝的量。

摘要： To effectively impart sizing performance to paper, while reducing the amounts of an internal sizing agent and aluminum sulfate, a papermaking additive comprises a mixture of an amphoteric copolymer having a hydrophobic group whose quaternization ratio is 40% by mole or more, and in which the ratio of the anion equivalent to the cation equivalent is 0.1 to 90%, and a calcium carbonate filler. The filler is one in which suitable water repellency is imparted to the filler. Hence, by adding this to pulp slurry, followed by a wet papermaking, the filler is efficiently adsorbed onto pulp fibers having anionic property, so that effective sizing performance can be imparted to the paper by using a smaller amount thereof than the internal sizing agent, while reducing the amounts of the internal sizing agent and the aluminum sulfate.

摘要： To provide a papermaking internal sizing agent capable of efficiently imparting sizing performance even in neutral papermaking which uses calcium carbonate as filler, and uses no aluminum sulfate or uses a small amount of aluminum sulfate, and also provide a paper or a paperboard obtained by using the papermaking internal sizing agent. The papermaking internal sizing agent comprises as an effective ingredient an amphoteric copolymer having hydrophobic groups and cationic groups, at least a part of the cationic groups being quaternized. Preferably, the amphoteric copolymer is obtained by polymerizing monomer ingredients that it essentially contain a hydrophobic monomer (A), a cationic monomer (B), and an anionic monomer (C) and that an anion equivalent of the monomer (C) is 0.1 to 90% of a cation equivalent of the monomer (B), in which a rate of quaternizing of the cationic groups is not less than 40% by mole. The paper or the paperboard contains the above papermaking internal sizing agent.
