A kind of imvite modified waterproof flame-retardant type biomass board and preparation method thereof, it is characterised in that by following step
Suddenly carry out：
A. the fragment of 10-20mm is cut to after rice straw is dried with pulverizer, be soaked in water 2-4d at room temperature,
Mechanical grinding adds sulfate wood pulp into fibre length 1-5mm, is well mixed, and injects beater, and wire-dividing broom purification makes beating
Degree is in 25-350SR, is slowly stirred addition Carboxyl Modified Polydimethylsiloxane, and tune pH is 4-5；
B. gelatin, nano imvite are mixed with distilled water, 40-50 DEG C of water-bath, stirring and dissolving obtains A liquid；Will
Emulsifier op-10, atoleine mix with rosin, and stirring and emulsifying 1-2h obtains B liquid；A, B liquid are mixed, is stirred, plus
Enter ethanol, continue to stir 1-2h, tune pH value of solution is 8-9, and 1-2h is solidified in ice-water bath, through vacuum drying, crushes to obtain microcapsule powder
End；
C. in polyacrylic acid 1:3-5 adds distilled water, is heated to 70-90 DEG C, and stirring is lower to add melamine phosphate, boric acid,
Ultrasonic disperse, reacts 3-4h, and cooling, suction filtration are washed 3-5 times, dried to constant weight in 80-90 DEG C of baking oven, then mixed with hydrotalcite
Grinding is closed, composite flame-retardant agent is obtained；
D. a, b, c resulting material are mixed, adds pine tar, stir 1-2h, obtain uniform sizing material, filling in a mold, uses hot press
2-4h shapings are compressed at 2-8MPa, 110-160 DEG C, that is, obtains a kind of imvite modified waterproof flame-retardant type biomass board.
Reaction mechanism of the invention is as follows：
（1）Strengthened by adding sulfate wood pulp wire-dividing broom purification, addition reinforcing agent Carboxyl Modified Polydimethylsiloxane in rice straw
Modification, adds foaming agent pine tar, and a kind of imvite modified waterproof flame-retardant type biomass board is obtained.
（2）Rosin powder contributes to the compacting of sheet material as filler, it is ensured that the consistency of sheet material；Rosin high temperature melting
Can be used as adhesive；Rosin has water insoluble characteristic, and addition can improve the water resistance of sheet material；Rosin molecule have double bond and
Carboxyl-reactive group, can participate in high temperature polymerization as monomer, form firm chemical bond, whole process environmental protection, low energy consumption, and system
Sheet material good mechanical properties, water-resistant type it is excellent.
It is nano montmorillonite modified to process the mechanical property and dimensional stability for being remarkably improved sheet material, montmorillonite and biomass
In mixed process, reaction is crosslinked, increased interaction, the water imbibition of the montmorillonite-composite biomass board after treatment
Can reduce, its dimensional stability is improved.
It is core with the atoleine for emulsifying, the gelatin with abundant dissolving is wall material, coagulant ethanol is added, using Dan Ning
Poly- method prepares microcapsules waterproofing agent；
（3）Melamine phosphate-polypropylene salt-borate fire retardant is prepared for, with hydrotalcite synergy, flame retardant effect is more
It is good；Phosphorous, nitrogen, not halogen in melamine phosphate molecule, and P- N cooperative effects can occur, and flame retarding efficiency is high, and heat endurance is good；
Boron is a kind of environment-friendly type raw material, there is flame retardant synergistic effect between boron-phosphorus-nitrogen；Intermediary water, carbonate are lost when hydrotalcite is heated
And hydroxyl, a large amount of heat absorptions, fire retardation is played, sour gas and smog can be absorbed, play a part of suppression cigarette, eliminate smoke.
