    Abstract: A polymeric dispersion in aqueous phase for use as a polymeric binder for paper and other nonwoven articles is described utilizing a polyisocyanate in combination with said polymeric binder to increase the ratio wet tensile/dry tensile strength. The polyisocyanate seems to be functioning by increasing the fiber to binder interaction rather than by simply increasing the strength/crosslink density of the binder. The polyisocyanate can be blocked isocyanate(s) or water dispersible isocyanate(s). The binder may or may not have isocyanate reactive species along the backbone.

    Abstract translation: 使用聚异氰酸酯与所述聚合物粘合剂组合来描述用作纸和其它非织造制品的聚合物粘合剂的用于水相的聚合物分散体,以增加湿拉伸/干拉伸强度比。 通过将纤维增加到粘合剂相互作用而不是简单地增加粘合剂的强度/交联密度,多异氰酸酯似乎起作用。 多异氰酸酯可以是封端的异氰酸酯或水分散性异氰酸酯。 粘合剂可以具有或不具有沿主链的异氰酸酯反应性物质。

    Abstract: Provided is a photo-curable type of orthopedic fixing material which can achieve a required strength by a visible light in a short time. A photo-curable resin which comprises a urethane (meth)acrylate oligomer having a structure represented by the formula (I), wherein A represents a diisocyante residue, and each of X and Y represents a (meth)acrylate residue having a hydroxyl group, and a photopolymerization initiator absorbing a light having a wave length of 400 to 700 nm is provided. The photo-curable resin (4) is held on a base material (3), to form a support material(5). The inside of the support material (5) is covered by a cushioning material (6) and the outside thereof is covered by a covering material (2), to prepare a splinting material (1) as an orthopedic fixing material. The cushioning material (6) side is applied to an affected part, a bandage is wound thereon, and the resulting package is subjected to molding with the irradiation of a visible light thereto. As a curing reaction proceeds, a splint is formed and the affected part can be fixed.

    Abstract translation: 提供一种能够在短时间内通过可见光获得所需强度的光固化型矫形固定材料。 一种光固化树脂,其包含具有式(I)所示结构的氨基甲酸酯(甲基)丙烯酸酯低聚物,其中A表示二异氰酸酯残基,X和Y各自表示具有羟基的(甲基)丙烯酸酯残基, 并提供吸收波长为400〜700nm的光的光聚合引发剂。 光固化树脂(4)保持在基材(3)上,形成支撑材料(5)。 支撑材料(5)的内部被缓冲材料(6)覆盖,并且其外部被覆盖材料(2)覆盖,以制备作为整形外科固定材料的夹板材料(1)。 将缓冲材料(6)侧施加到受影响部位,将绷带缠绕在其上,并将所得包装经受可见光照射而成型。 随着固化反应的进行,形成夹板并使受影响的部件固定。
