摘要： PROBLEM TO BE SOLVED: To obtain a rubber molded product exhibiting excellent antimicrobial property without producing sliminess even if used for a long period. SOLUTION: This rubber molded product is obtained by uniformly dispersing water-soluble glass powder containing silver ion in a ration of 0.1-20% expressed in terms of silver oxide into a substrate rubber and particle diameter of the powder is 0.05-100 μm and a weight ratio of glass powder: substrate rubber is (0.1-20):100. In this time, SiO2 -Na2 O or SiO2 -B2 O3 -Na2 O is preferable as a glass composition for glass powder and a thermoplastic elastomer is preferable as the substrate rubber. Rubber molded product having excellent antimicrobial property and antifungal property are obtained by elution of silver ion from a silver-containing water-soluble gas powder and the rubber molded product is suitable as a disk-like cover 1 of discharge port for kitchen sinks, packing for glass fixing of window sash and door packing for refrigerators.

摘要： PURPOSE:To obtain a sheetlike antimicrobial agent composed only of glass fiber with hardly any problems in deterioration of yield in production without any chemical problems caused by a binder due to no use thereof. CONSTITUTION:This sheetlike antimicrobial treating agent is composed of a binder-free nonwoven fabric obtained by blending and forming a sheet of paper from Ag-containing glass fiber containing monovalent silver ions and ultrafine Ag-free glass fiber without containing the silver ions using no binder. Thereby, the sheetlike antimicrobial treating agent can be produced with a high productivity by blending and forming the sheet of paper from the Ag- containing glass fiber with the Ag-free glass fiber. A sufficient sheet strength can be obtained by bonding effects of the ultrafine Ag-free glass fiber.

摘要： PURPOSE:To make it possible to obtain the title material which, even when it is used in a relatively lower effective concentration, can exhibit its excellent antifouling action for a long time without polluting marine environments and is capable of being controlled in its antifouling power by incorporating monovalent Ag-containing water-soluble glass particles in a coating material. CONSTITUTION:This antifouling resin coating material is prepared by mixing a synthetic resin coating material with a powder obtained by adding 0.1-20 pts.wt. (in terms of Ag2O) monovalent Ag to 100 pts.wt. water-soluble glass (e.g., a mixture of 40.0mol% SiO2, 50.0mol% B2O3 and 10.0wt.% Na2O), melting the resulting mixture by heating and quenching the melt. This material is used to prevent vessels, marine and submarine structures, apparatuses related to cooling water of a thermal power plant, fishnets, etc., from being fouled by the deposition of marine animals and plants.

摘要： PURPOSE:To obtain an easily handleable, safe and low-cost resin material having bacteriostatic, deodorizing and highly water-absorbing properties, by mixing a powder, granule and/or block of a water-soluble glass containing univalent silver ion in the composition to a highly water-absorbing resin carrier and supporting the glass powder, etc., in the carrier. CONSTITUTION:(A) A highly water-absorbing resin, e.g. a crosslinked sodium polyacrylate produced from acrylic acid obtained by the vapor-phase oxidation of propylene is uniformly mixed with (B) a water-soluble glass containing Ag in the composition, e.g. containing 0.1-2.5pts.wt. of Ag (in terms of Ag2O) in 100pts.wt. of a mixture of SiO2, B2O3 and Na2O. The mixture is melted at 1,100-1,300 deg.C for 60min and quenched to obtain the component A supporting the powder, granule or block of the component B or their mixture. The highly water-absorbing resin material produced by the above process slowly releases bacteriostatic Ag at a constant rate when the component B is while contacted with and dissolved in the liquid absorbed in the component A.

摘要： PURPOSE:To prevent a cutting oil from decomposing or emitting an offensive odor for a long period of time at a low cost, by immersing a mass of water-soluble glass contg. Ag and wrapped in a water-permeable fiber cloth in a cutting oil or the like diluted with water to elute Ag ions while dissolving the glass through gelation of the glass. CONSTITUTION:Solid matter comprising water-soluble glass in the form of a mass, particle, a powder, or any combination thereof and composed of 100pts.wt. glass compsn. contg. at least one of SiO2, B2O3, and P2O5, at least one of Na2O, K2O, CaO, MgO, BaO, and ZnO, and at least one of Al2O3 and TiO2 and 0.1-2.5pts.wt. Ag2O is wrapped in a water-permeable fiber cloth comprising a (non)woven fabric or a synthetic resin sheet in such an amt. as will provide a solid concentration of 300-1,000g/m . The wrapped solid matter is immersed in a cutting oil or a grinding oil diluted with about 10-100-folds as much water. This not only prevents a suspendible substance and suspended matter contained in the oil from penetrating into the inside of the cloth through the mesh of the fiber cloth and, at the same time, causes Ag ions to be gradually eluted outside the fiber cloth through a gelation of the glass, thereby preventing the oil from decomposing and emitting an offensive odor.

摘要： PURPOSE:To preserve a medicated bath by preventing the generation of a putrid smell and slime by the sterilizing and bactericidal action of an eluted Ag ion by immersing water-soluble glass containing monovalent Ag in its composition in the medicated bath as a water treatment agent. CONSTITUTION:A water treatment agent composed of water-soluble glass containing monovalent Ag in its composition is immersed in a medicated bath (e.g. hot bath water having a natural herb, a herb for a herb medicine, citrus fruits and a synthetic bathing agent dissolved therein) and an Ag ion is eluted from said glass to treat and preserve the medicated bath. The water-soluble glass is prepared by containing, for example, Ag2O in a composition containing mesh forming oxide composed of one or more kind of SiO2, B2O3 and P2O5, mesh modifying oxide composed of one or more kind of Na2O, K2O or CaO and intermediate oxide such as Al2O3 or TiO2 as monovalent Ag. A pref. composition consists of SiO2 15-80, B2O3 30-70, Na2O 7-20 and Ag2O 0.1-2.5 on a basis of pts.wt. In use, said composition is immersed as it is or wrapped in water permeable cloth.

摘要： PURPOSE:To prevent the malodor caused by the decomposition due to the reproduction of microbes by eluting silver ions into a water-soluble oil solution from a woven fabric or a nonwoven fabric containing soluble silver ion-containing glass. CONSTITUTION:This floor mat is made of a porous sheet containing granular or fiber-like silver ion-containing galss. The content of the silver ions must be 0.1wt.% or above as converted into Ag2O for showing an antibacterial action, and 5 wt.& is sufficient. The average particle diameter is set to 500mum or below, normally to 5mum or above in view of the adjusting work of the particle diameter. In the case of fibers, the average fiber diameter is set to 100mum or below for the antibacterial performance, normally to 0.5mum or above in view of the fiber spinning work efficiency. The porosity of the porous sheet is set to the range of 390-vol.%, and the thickness is normally set to the range of 0.3-5mm. When the thickness is thinner than 0.3mm, the antibacterial performance is inferior, and the antibacterial performance is not improved even if the thickness is made thicker than 5mm. The sliver ion-containing glass is stuck on the surface of a woven fabric with an organic or inorganic binder.

摘要： PURPOSE:To make it possible for a synthetic resin molding to destroy bacteria by Ag ions released from it and to exhibit a mildewproof and deodorizing effect by allowing a synthetic resin molding to carry a water-soluble glass particles containing Ag ions. CONSTITUTION:A synthetic resin molding (e.g., a flexible vinyl chloride resin sheet product such as a vinyl cloth, a synthetic leather, a building and construction material, furniture or a bathtub) is allowed to carry water-soluble glass containing Ag ions (silver glass) particles. The obtained molding can be rendered antibacterial and can be endowded with a mildewproof and deodorizing effect because it can release Ag ions from the water-soluble glass which is dissolved by contact with a liquid or a gas.
