    摘要： The present invention relates to an inorganic antibacterial agent comprising a thermoplastic resin and inorganic antibacterial particles dispersed in the resin, and a shape factor SF2 defined by the following formula: SF2=100πL2/(4A) (Wherein L represents a perimeter of a plane image of a particle which is obtained from observation of a slice for inorganic antibacterial agent using a transmission electron microscope, and A represents the area of the plane image.) is not more than 200, and the existing ratio defined by the following formula: Existing ratio (%)=100×(number of inorganic antibacterial particles having SF2 of not more than 200)/(number of particles used for calculation of SF2) is not less than 80%. According to the present invention, when the inorganic antibacterial agent is dispersed in the antibacterial molded resin product, the dispersion of inorganic antibacterial agent is improved since inorganic antibacterial particles are dispersed in the thermoplastic resin. Moreover, inorganic antibacterial particles are dispersed homogeneously in the base resin since the occurrence of agglomeration and localization are well prevented in the thermoplastic resin.

    摘要翻译： 本发明涉及包含分散在树脂中的热塑性树脂和无机抗菌颗粒的无机抗菌剂和由下式定义的形状因子SF2：SF2 = 100piL2 /（4A）（其中L表示 使用透射电子显微镜从无机抗菌剂的切片观察得到的粒子的平面图像，A表示平面图像的面积）不大于200，并且由下式定义的现有比例 ：现有比例（％）= 100×（SF2为200以下的无机抗菌颗粒数）/（SF2的计算用颗粒数）不小于80％。 根据本发明，当无机抗菌剂分散在抗菌树脂制品中时，由于无机抗菌颗粒分散在热塑性树脂中，无机抗菌剂的分散性得到改善。 此外，无机抗菌颗粒均匀地分散在基础树脂中，因为在热塑性树脂中很好地防止了聚集和定位的发生。

    摘要： Anti-bacterial composite particles which comprise a polymer base material comprising a thermal melting polymer, such as a polyolefine, exhibiting good dispersibility in a basic material resin and having a lower molecular weight or a lower softening point than that of the basic material resin, and inorganic fine particles comprising a metal having anti-bacterial activity carried thereon. An antibacterial resin composition can be prepared by melting and kneading a synthetic resin composition as the basic material resin together with the anti-bacterial composite particles and forming by known molding methods such as extrusion molding and injection molding, and can be used for producing various synthetic resin moldings which have an inorganic anti-bacterial agent uniformly dispersed in a synthetic resin composition and thus exhibits good anti-bacterial effect.
