燃性を維持しながら、熱安定性の低下を防止する難燃剤
として好適なホウ酸亜鉛を見出すに至った。In recent years, there has been a great demand for flame retardancy in synthetic resin building materials, interior materials, and electric wires. Although halogen compounds and antimony compounds are often used as flame retardants, zinc borate has recently attracted attention as a flame retardant that also prevents molten dripping during the burning of synthetic resins. 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. As a result of earnest studies in view of such a situation, the present inventors have found zinc borate suitable as a flame retardant for preventing deterioration of thermal stability while maintaining the flame retardancy of zinc borate.
すなわち本発明は、エポキシ化合物で処理したことを特

ば、平均粒径が20μｍ以下のものが好ましい。The zinc borate used in the present invention is not particularly limited, but in view of dispersibility in a synthetic resin and flame retardancy, an average particle size of 20 μm or less is preferable.

-Epichlorohydrin condensate, cresol novolac type epoxy resin, etc. may be mentioned. These epoxy compounds are preferably used in an amount of 1 to 20% by weight based on zinc borate, and if the amount is less than 1% by weight, the desired thermal stability cannot be obtained.
When it exceeds the weight%, flame retardancy is lowered.

行なわれると、熱安定性の向上が著しい。Although it is a method of treating zinc borate with an epoxy compound, a simple mixing treatment with a V blender, a ribbon blender, or the like is not as effective as when it is individually blended with a synthetic resin, but is a Henschel mixer / super mixer. -When the mixing treatment is carried out by a roller mill, a ball mill or the like under a milling condition that causes a mechanochemical reaction, the thermal stability is remarkably improved.
