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
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
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.
