From, then be dried to moisture content through mechanical crushing, 90-100 DEG C and be 3-5%, cross the screening of 10-60 mesh sizes, pneumatic concentration removal corn
Stalk flesh, obtain maize straw particle, dry storage；
B. waste rubber powder surface modification treatment：
By 20-30 parts by weight junked tires mechanical crushing, 60-80 mesh sieves are crossed, obtain waste rubber powder；
Distilled water is added into ethanol, is made into the solution that alcohol content is 90-95%, it is 4-6 to add second acid for adjusting pH, and stirring is lower to be added
Enter 0.5-1 parts by weight silane couplers, hydrolyze 5-10min, it is uniformly sprayed at rubber powder surface, is sufficiently mixed；In 500-
5-10min is handled under 700W microwaves, is soaked with sodium hydroxide solution, is warming up to 50-60 DEG C of stirring 20-30min；Then in 80-
4-6h is dried in 90 DEG C of baking ovens, produces modified rubber powder；
C. resulting material in a, b is well mixed with 1-2 parts by weight polysiloxanes, 4-8 part by weight of boric acid zinc, obtains premix, thrown
Enter in multi-functional glue mixer, premix is stirred in glue spraying, mated formation uniformly, and a strata is respectively placed on plate two sides
Four fluorine ethylene plastic sheetings；
D. precompressed, hot-pressing processing technique：
At room temperature, the loose slab that gained paves in c is compacted with 50 tons of preformers, reusable heat press is in 140-160 DEG C
Finished product is made in the plate hot pressing 5-10min of pre-molding, by sheet material by after standard clipping, cutting edge as being placed in climatic chamber
1-2d, the gained composite plate.
Wherein, silane coupler described in step b is Si69, concentration of sodium hydroxide solution 40-50%.Described in step c
The resin added of isocyanate adhesive is 6-10%.Preload pressure described in step d is 3-5MPa, time 2-4min, and constant temperature is permanent
30-50 DEG C of wet tank temperature, humidity 30-35%.
The present invention reaction mechanism and have the beneficial effect that：
First waste rubber powder is handled with silane coupler, increases the hydroxy number on its surface, strengthens its polarity, is improved multiple
The mechanical property of condensation material；Microwave modification rubber powder is used again, enhances the activity on rubber powder surface, can be with corn after microwave modification
Crushed straw aggregate forms close combination, and microwave makes rubber powder surface oh group occur, is advantageous to the combination between timber；Most
Sodium hydroxide solution immersion treatment is used to rubber powder afterwards, by alkali process lumber fibre can be promoted preferably to be tied with rubber powder
Close.
Polysiloxanes and Firebrake ZB compositional flame-retardant, polysiloxanes is organic reagent, can improve point of fire retardant in the material
Property is dissipated, improves the mechanical property of material；Crosslinked action between compound flame retardant and matrix be present, suppress the cracking of matrix, during high temperature
Polysiloxanes is cracked to form silica separation layer, plays condensed phase buffer action；Both have synergistic fire retardation.
Embodiment
In order that the technical means, the inventive features, the objects and the advantages of the present invention are easy to understand, tie below
Specific embodiment is closed, the present invention is expanded on further.
