Open the glass jar, stir and mix with a glass rod for 30 minutes to obtain modified straw gluten ash; mix and soak the rice husk with water at a mass ratio of 1:30 for 4 hours, filter to obtain the filter residue, freeze the obtained filter residue, and then crush it The latter filter residue is moved into an oven and dried to a constant weight at a temperature of 110°C to obtain dried rice husk powder. Then the dried rice husk powder is transferred to the carbonization furnace, and the temperature is programmed at a rate of 15°C/min under nitrogen protection. To 600℃, heat preservation and carbonization for 5h, and discharging to obtain carbonized rice husk; in parts by weight, take 10 parts corn starch, 10 parts carbonized rice husk, 30 parts modified straw gluten ash, 40 parts humic acid, 50 parts Part of the water, first pour the corn starch and water into the beaker, stir and mix with a glass rod for 15 minutes, then let stand for 4 hours to swell, and then add the carbonized rice husk, modified straw gluten ash and humic acid to the beaker in turn, continue to stir and mix 30min, get the biomass binder; in parts by weight, add 50 parts of bauxite, 20 parts of kyanite, and 100 parts of water glass to the ball milling tank, and the ball-to-material mass ratio is 20:1. Add zirconia ball milling beads to the tank, mix for 6 hours by ball milling, and discharge the material to obtain the ball abrasive, which is the inorganic binder; in parts by weight, take 50 parts of polymer binder and 60 parts of biomass binder in turn, 30 parts of inorganic binder are mixed with a mixer at a high speed of 1500r/min for 60 minutes, and the material is discharged to obtain a composite coal binder. The thermosetting phenolic resin is phenolic resin 2123. The curing agent is benzenesulfonic acid. The organosilicon is phenyltrichlorosilane. The petroleum resin is C5 petroleum resin. The humic acid is coal humic acid. The modulus of the water glass is 2.5.

[0028] In parts by weight, take 20 parts of thermosetting phenolic resin, 0.8 parts of curing agent, 40 parts of organic silicon, and 20 parts of petroleum resin in sequence, add them to the mixer, stir and mix for 45 minutes at a speed of 600r/min, and discharge , Get a polymer binder; cut the straw into short straw stalks with a length of 5cm with a guillotine, and lay the short straw stalks on the bottom of the glass jar, control the laying thickness of the short straw stalks to 5cm, and then lay a layer of quicklime on the surface of the short straw stalks , Such a layer of short straw stalks and a layer of quicklime are laid layer by layer, and then water is added to the glass jar along the wall of the glass jar until the water surface submerges the material laid in the glass jar, and then the glass jar is sealed and left to soak and rot for 30 days. Open the glass jar, stir and mix with a glass rod for 30 minutes to obtain modified straw gluten ash; mix and soak the rice husk with water at a mass ratio of 1:30 for 4 hours, filter to obtain the filter residue, freeze the obtained filter residue, and then crush it The latter filter residue is moved into an oven and dried to a constant weight at a temperature of 110°C to obtain dried rice husk powder. Then the dried rice husk powder is transferred to the carbonization furnace, and the temperature is programmed at a rate of 15°C/min under nitrogen protection. To 600℃, heat preservation and carbonization for 5h, discharge the material to obtain carbonized rice husk; in parts by weight, add 50 parts bauxite, 20 parts kyanite, and 100 parts water glass to the ball milling tank according to the mass of the ball. With a ratio of 20:1, add zirconia ball milling beads to the ball mill tank, mix the ball mill for 6 hours, and discharge the material to obtain the ball abrasive, which is the inorganic binder; in parts by weight, take 50 parts of the polymer binder in turn, 30 Part of the inorganic binder is mixed with a mixer at a high speed of 1500r/min for 60 minutes and discharged to obtain a composite coal binder.

[0030] Cut the straw into short straw stalks with a length of 5 cm. Lay the short straw stalks on the bottom of the glass jar to control the laying thickness of the short straw stalks to 5 cm. Then lay a layer of quicklime on the surface of the short straw stalks. Lay layers of quicklime layer by layer, then add water to the glass jar along the wall of the glass jar until the water surface submerge the material laid in the glass jar, then seal the glass jar, let it stand for 30 days soak and rot, open the glass jar and stir with a glass rod Mix for 30 min to obtain modified rice straw gluten ash; mix rice husk and water at a mass ratio of 1:30 to soak for 4 hours and filter to obtain filter residue. The obtained filter residue is frozen and crushed, and then the crushed filter residue is transferred to the oven. Dry rice husk powder at 110℃ to constant weight to obtain dried rice husk powder, then transfer the dried rice husk powder to a carbonization furnace, program it to 600℃ at a rate of 15℃/min under nitrogen protection, and keep carbonizing for 5 hours. Discharge the material to obtain carbonized rice husk; take 10 parts of corn starch, 10 parts of carbonized rice husk, 30 parts of modified straw gluten ash, 40 parts of humic acid, and 50 parts of water in order in parts by weight.
