摘要： PURPOSE:To provide a zeolite-based inorganic antibacterial agent having excellent light-resistance and heat-resistance, its production process and an antibacterial resin composition. CONSTITUTION:The inorganic antibacterial agent of the present invention is composed of fine antibacterial metallic silver powder pressed and supported on a zeolite carrier. The inorganic antibacterial agent is produced by mechanically crushing a mixture of zeolite powder and antibacterial metal powder to effect the homogeneous mixing of the components and to support the fine antibacterial metal powder on the zeolite carrier. An antibacterial resin composition can be produced by compounding 0.05-50 pts.wt. of the inorganic antibacterial agent to 100 pts.wt. of a synthetic resin.

摘要： PURPOSE:To obtain a lightweight foam having a uniform particle diameter in a desired color without corners with an excellent granulation efficiency by granulating an expandable coating material consisting of a core material, SiO2, Al2O3 and an alkali which are principal components at a specific ratio and thermally expanding the resultant granulated material. CONSTITUTION:A coating material consisting of an expandable inorganic substance containing a core material, SiO2 and Al2O3 and an alkali as principal components at 3.0-6.0 molar ratio of the [(SiO2+Al2O3)/M2O] (M is alkaline metal) is used as a raw material. The obtained raw material is granulated to provide a granulated substance in which the periphery of the core material is coated with the coating material. The granulated substance is subsequently heated and expanded at a temperature without melting the core material to afford an inorganic foam. The core material is lightweight and has bubbles or is an expandable material with preferably >=100mu particle diameter. The coating material is obtained by suitably combining expandable powder with an alkaline agent, a foaming agent and other inorganic substances, etc., and preferably has a smaller particle diameter than that of the core material.
