An improved production method for burned rice grain insulating materialwhich comprises the following steps: (a) burn the rice to make the rice become black rice ash; (b) after the black rice ash cools down, mix the black rice ash with the fly ash, in which the black rice ash is 85-92 wt% of the total used amount, the fly ash is 8-15 wt% of the total used amount; the fly ash is a collection during the process of grinding the rice into powder or an accumulation of the dusts in the waste gas of the rice shedder blower; prior to the mixing, the fly ash was added with water and soda (NaOH) to turn the mixture into viscous; the viscous fly ash is used to mix and stick the burned rice ash together; (c) feed the mixed rice ash and fly ash into an extruder to prepare grains; and (d) dry the burned rice grain insulating material.
