ングと呼ばれる如く、その低下が著しい。In recent years, there has been a great demand for flame retardancy in building materials and interior materials made of synthetic resins, electric wires and the like. Although halogen compounds and antimony compounds are frequently used as flame retardants, zinc borate has recently been attracting attention as a flame retardant that also prevents molten dripping of synthetic resins during flame retardation. However, when zinc borate is blended with a synthetic resin, it causes a decrease in thermal stability during the molding process, and particularly in a resin containing a halogen such as a vinyl chloride resin, such a decrease is caused as called zinc burning. Remarkable.

た。The inventors of the present invention use zinc borate as a measure for preventing a decrease in thermal stability while maintaining the flame retardancy of zinc borate, by using hydrotalcite compounds, polyhydric alcohols or polyhydric alcohol partial esters, epoxy compounds. It has already been found that each of these compounds can be treated alone, but this time, it was found that the combined use of two or more of these compounds is effective in further improving the thermal stability, and the present invention has been completed.
