methods for inhibiting strength loss in cellulosic material and providing flame retardant composition, liquid flame retardant composition and strength loss inhibitor for cellulosic material and cellulosic material

摘要

A liquid flame retardant composition is in the form of a mixture comprising a phosphate, ammonium hydroxide and zinc borate flame retardant. The invention extends to a method of providing a phosphate-based liquid flame retardant composition, the use of a phosphate-based flame retardant, ammonium hydroxide and a zinc borate in the manufacture of a flame-retardant liquid composition. to a cellulosic material treated with the flame retardant liquid composition and a method of inhibiting loss of strength in cellulosic material when the cellulosic material is exposed to heat.
