More specifically, the present invention relates to a foamable thermoplastic resin composition for electric wires having antibacterial and antifungal functions, which is characterized by containing a zeolite holding a metal having a bactericidal effect, that is, an inorganic antibacterial zeolite. .

所黴の発育がi認された。Conventionally, plastic foam resins have been believed to be highly resistant to microorganisms such as fungi (mold) and bacteria, but there have been reports of damage to foamed electric wires caused by microorganisms. In addition, stabilizers, fillers, antioxidants, ultraviolet absorbers, lubricants, colorants, etc. are added to foamed wires, but these are also sensitive to minute substances. When a foaming agent was added and molded into an electric wire, the electric wire was subjected to a mold resistance test according to the method of J.R.S. Z-2911, and mold growth was observed.

That is, although organic chlorine and organic sulfur compounds have been used, their antibacterial properties, antifungal properties, and low toxicity are not necessarily satisfactory. In particular, since electric wires are used for more than 10 years, and some are used semi-permanently, their antibacterial and anti-mildew effects need to last for a long time.

に至った。In order to prevent the generation of mold, the present inventors conducted extensive research on antibacterial and antifungal agents for foaming lines, and found that a foamable thermoplastic containing zeolite that retains antibacterial metal ions was developed.

When a part or all of the ion-exchangeable ions are replaced with ammonium ions and antibacterial metal ions, a foamable thermoplastic resin composition that exhibits less discoloration over time after foaming and wire molding can be obtained. The present invention was completed based on these favorable findings.

たNo。For each sample, water was added to 1 kg of zeolite powder that had been heated and dried at 110°C to make a slurry of 1.3 Il, which was then stirred and degassed, and an appropriate amount of 0.5N nitric acid solution and water were added. Adjust pH to 5-7, total volume to 1.8
A slurry of No. 1 was prepared. Next, for ion exchange, a mixed aqueous solution 31 of a specified salt at a specified concentration was added to bring the total volume to 4.8 Il.
This slurry liquid was maintained at 40 to 60°C and heated to 10 to 2
The mixture was stirred for 4 hours and maintained at an equilibrium state. After ion exchange, the zeolite powder was filtered and washed with room temperature water or hot water until there were no excess ions, copper ions, or zinc ions in the zeolite phase.
Six types of samples were obtained by heating and drying at 10°C. Obtained no.
