Embodiment 1

[0013] (1) Al(OH) 3 Add the fine powder and NaOH fine powder to the pyrophyllite powder, add 250ml of water after mixing, knead evenly, dry, put it in a muffle furnace and heat up to 780°C for 3 hours, take it out, cool it, and grind it to make mature soil.

[0014] (2) Using water glass and high-alkali sodium metaaluminate solution as raw materials, the molar composition of Na 2 O: Al 2 o 3 :SiO2 2 :H 2 O=14:16:14:300 Feeding, slowly mix the two under stirring at 80°C, continue to stir for about 20 minutes after mixing, and then place it in a water bath at 30°C for static aging to obtain the guiding agent .

[0015] (3) Put 3g of mellow soil and 250ml of distilled water into a beaker in a water bath at 65°C and gel for 2 hours, then add 10ml of directing agent, continue to stir for 30 minutes, and transfer it to a crystallization bottle Shake intermittently in a boiling water bath, crystallize for 2 hours, fully rinse with deionized water to pH<10.5 during suction filtr...

Embodiment 2

[0018] (1) Al(OH) 3 Add the fine powder and NaOH fine powder to the pyrophyllite powder, add 270ml of water after mixing, knead evenly, dry it, put it in a muffle furnace and heat it up to 750°C for 3 hours, take it out, cool it, and grind it to make mature soil.

[0019] (2) Using water glass and high-alkali sodium metaaluminate solution as raw materials, the molar composition of Na 2 O: Al 2 o 3 :SiO2 2 :H 2 O=15:7:10:320 Feed, slowly mix the two under stirring at 70°C, continue to stir for 25 minutes after mixing, and then put them in a water bath at a certain temperature for static aging to prepare the guiding agent.

Abstract

The invention discloses a preparation method of a mesoporous composition material wood fire retarding agent. The preparation method comprises the following steps of:(1) adding watering in Al(OH) 3, NaOH and pyrophyllite powder, mixing and uniformly kneading, and drying, roasting and grinding to manufacture mellow soil; (2) mixing and stirring water glass and a high alkali sodium metaaluminate solution, and placing in a water bath to manufacture a guiding agent after aging; (3) mixing and gluing the mellow soil and water, adding the guiding agent, shifting in a crystallization bottle to crystallize in a boiling water bath, and filtering after crystallization and drying; and (4) mixing and grinding ammonium polyphosphate and melamine to manufacture a mouldboard agent solution, dissolving the product obtained in the step (3) in the mouldboard agent solution, adding Fe (NO3)3 and heating, and finally carrying out PH value washing and drying so as to obtain the mesoporous composite material wood fire retarding agent. The preparation method provided by the invention has the advantages that the flame retardant smoke repressing effect is good, the process is simple, the industrialization is easy to realize, the cleaning and pollution are free and the like, the mesoporous composite material solution is injected in solid wood, wood single plates, wood fiber or woodwool by a vacuum-pressure method, and the high efficiency flame retardant solid wood or flame retardant artificial plate is manufactured.

Description

Technical field [0001] The present invention involves the preparation method of wood retardant, which is specifically for a prepared method for a medium composite material as a wood flame retardant. Background technique [0002] The fire is a common catastrophic issue facing people in the world. It has caused huge life and property losses to human society.With the gradual improvement of people's living standards, the consumption of polymer materials and wooden materials for architecture and interior decoration increased year by year.However, the polymer materials and wooden materials are flammable and combustible materials, which can easily lead to the spread of fire. When burning, a large amount of thermal energy exacerbates the fire hazards. A large amount of smoke and gas released can cause poisoning and casualties.Therefore, flame retardant and smoke suppression treatment of polymer materials, wooden materials, etc. are related to the needs of life safety and property. [000...
