れるなどの諸傾向も見られる状況にある。Chlorine-containing polymeric materials such as vinyl chloride or chloroprene rubber have excellent flame retardant properties.
It is used in large quantities in coating materials for various electric wires and cables, electrical parts, panel materials, sealing materials, etc., and in recent years there have been trends such as the use of such flame-retardant materials becoming mandatory from a disaster prevention perspective. It is in.

ガスによる周辺機器の腐蝕など経済的損失のみならず、
最悪の場合には有害な塩化水素ガスによる人身への事故
等の発生の恐れもあるなど重大な問題があった。However, on the other hand, such chlorine-containing polymer materials release a large amount of hydrogen chloride gas when burned, and when a disaster occurs, the hydrogen chloride gas not only causes economic losses such as corrosion of peripheral equipment, but also causes
In the worst case scenario, there was a serious problem such as the risk of personal injury due to harmful hydrogen chloride gas.

In addition, examples of oxides, hydroxides, and carbonates of Group 0 metals of the periodic table include calcium oxide, calcium hydroxide, calcium carbonate, magnesium oxide, magnesium hydroxide, magnesium carbonate, sodium hydrogen carbonate, and potassium hydrogen carbonate. Calcium carbonate and magnesium carbonate are particularly preferred because they generally have excellent miscibility with resins. The amount to be added to 1.00 parts by weight of the polymeric substance depends on the chlorine content in the polymeric substance used, but it is required to be at least 50 parts by weight.
