ある。(Function) To explain the function and effect of this invention, firstly, the silica gel contained as the main component of this flame retardant paper is
It thermally decomposes at a temperature of 34.2% (by weight) of water, which is theoretically reduced. Therefore, the flame retardant property is much better than the conventionally used hydroxide ariminilum which releases 23% (weight ratio) of water at high temperatures of 150°C to 300°C. Therefore, it exhibits flame retardant properties for a longer period of time at lower temperatures than aluminum hydroxide. It also has strong paper strength and can be handled in the same way as regular paper. As a filler, silica gel exhibits flame retardant properties with good dispersion and a uniform composition, and also has the effect of reducing aggregation due to electric charge.
