METHOD OF MANUFACTURING A FLAME-RETARDANT HEAT INSULATING FORMED PRODUCT
A method of manufacturing a flame-retardant heat insulating formed product in the shape of a mat includes pouring water in used paper or a pulp material to defibrate and obtain defibrated cotton. A flame retardant such as a boric acid is charged into the defibrated cotton. By stirring and heating, a flame-retardant heat insulating defibrated cotton is obtained. Short fibers with a low melting point made of polyester or the like are charged into the flame-retardant heat insulating defibrated cotton. By mixing and stirring, a flame-retardant heat insulating loose material is obtained. A forming die made of corrugated cardboard provided with a lid having air vents is filled with the flame-retardant heat insulating loose material. The flame-retardant heat insulating loose material together with the forming die are heated with a microwave heating apparatus to form. A mat-shaped formed product is removed from the forming die.
