Abstract

The invention discloses a composite coal binder, and belongs to the technical field of solid fuel binders. The composite coal binder provided by the invention consists of the following raw materials in parts by weight: 30-50 parts of a polymer binder, 40-60 parts of a biomass binder and 10-30 parts of an inorganic binder, wherein the polymer binder is prepared by mixing thermosetting phenolic resin, a curing agent, organic silicon and petroleum resin; the biomass binder is prepared by mixing corn starch, carbonized rice husk, modified straw strip mixed lime mortar, humic acid and water; and the inorganic binder is prepared by mixing bauxite, kyanite and water glass. The composite coal binder provided by the invention has good bonding performance at different combustion temperatures, size stability performance of briquette coal at different combustion temperatures can be effectively guaranteed, and the briquette coal can be prevented from being disintegrated in a combustion process. Thebinder provided by the adhesive disclosed by the invention is used to solve the problem that the size stability of coal prepared by using a conventional binder is poor, and solve the problem that disintegration easily occurs in the combustion process.

[0025] Example 1
[0026] 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, 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.
