される。In general, the mechanism of action of phosphorus as a flame retardant is that non-phosphoric acid produced by heating during combustion becomes metaphosphoric acid or polymetaphosphoric acid, and a non-volatile phosphoric acid polymer is formed on the solid or molten phase of the burning plastic. Ammonium phosphate, which is known to form a film and thereby exhibit a flame retardant effect, is further added in the present invention.
It is believed that K promotes the production of the above-mentioned polymetaphosphoric acid, etc., and that K itself releases ammonia upon heating, acting as a dehydration carbonization catalyst. It is assumed that this will have a positive effect.
