And fiberboard preparation etc..
Wang Cheng is far away from its master thesis《The preparation and water resistance research of coal ash fiberboard》In, using wet method system
Plate technology utilization coal ash fiber prepares sheet material, and coal ash fiber is loosened except Slag treatment by water conservancy stirring means, ground
The factors such as adhesive polyethylene alcohol, coal ash fiber slurry agitation jitter time, coal ash fiber concentration, additive have been studied carefully to powder
The influence of coal ash fiberboard mechanical property, improved by modified coal ash fiber, modified adhesive and using waterproof coating
The water resistance of coal ash fiberboard.But combination property, water resistance deficiency be present.
The content of the invention
The present invention solves the technical problem of provide a kind of polyvinyl alcohol-paraffin wax emulsions composite modified water proof type powder
Coal ash fiberboard and preparation method thereof, the fiberboard prepared according to the technique possess good combination property and water resistance.
The technical problems to be solved by the invention are realized using following technical scheme：
A kind of preparation method of the based Wood Adhesives based on esterification modification tapioca, it is characterised in that carry out according to the following steps：
A. 4-7 parts by weight esterifying agents maleic anhydride, 1-2 parts by weight oxygen sodium oxide molybdena are mixed, 1:5-10 is dissolved in distilled water
In, obtain A liquid；20-30 parts by weight tapiocas are put into pulverizer and crushed, spraying treatment are carried out to it with A liquid, mixing is equal
Even, it is 5-10% to be put into 40-50 DEG C of baking oven and be dried to moisture, is warming up to 90-110 DEG C of reaction time 3-4h, is down to room temperature,
Filtering, alcohol are washed 3-5 times, are dried in 50-60 DEG C of baking oven, are crossed 80-100 mesh sieves, are obtained esterification modification tapioca；
B. by poly-vinyl alcohol solution heating water bath to 70-80 DEG C, lower addition 6-9 parts by weight borax solns are stirred, constant temperature stirring is anti-
After answering 1-2h, mix, stir with 3-5 parts by weight of urea, 1-2 parts by weight hydrogen peroxide, it is 5- to adjust pH with 1-2mol/L HCl
6, add 1-3 parts by weight of ferrous sulfate, be incubated 50-60 DEG C of stirring reaction 30-50min, 1-2 parts by weight of phosphoric acid tributyls are added dropwise, stir
Mix uniformly, be cooled to room temperature, adjust pH to obtain hydrophobically modified polyvinyl alcohol glue for neutrality；
C. by 6-10 parts by weight paraffin, heating water bath, stirring fusing are slow to add 2-3 parts by weight polysorbate60,1-2 at 85-95 DEG C
Parts by weight sorbester p18, stirs, and 1:3-5 adds distilled water, continues constant temperature stirring 1-2h, adds 5-8 weight parts of methacrylic acid first
Ester, 0.1-0.2 parts by weight potassium peroxydisulfates, 3-4h is reacted in 70-80 DEG C of stirring and emulsifying, room temperature is cooled to, with 100-200 eye mesh screens
Filtering and discharging, obtain complex emulsions waterproofing agent；
D. resulting material in a, b, c is mixed with 6-11 parts by weight styrene-acrylic emulsion, 1-2 parts by weight initiator potassium persulfates, room temperature
Under be sufficiently stirred, standing and defoaming, obtain a kind of based Wood Adhesives.
Wherein, poly-vinyl alcohol solution described in step b is to add distilled water into 50-60 weight account polyethylene alcohol, heating
1-2h is stirred to 90-100 DEG C of heating water bath, obtains the solution that mass fraction is 8-10%；Borax soln concentration is 3-5%.In step c
The emulsion reaction mixing speed is 1000-1100rpm.Styrene-acrylic emulsion solid content described in step d is 40-45%.
The present invention reaction mechanism and have the beneficial effect that：
With tapioca esterification occurs for maleic anhydride, tapioca particle is diminished, specific surface area increases, hydrophobicity
It can improve；With polyvinyl alcohol (PVA) for adhesive, nonhazardous, but its poor water resistance, first polyvinyl alcohol is changed with borax
Property, reaction is crosslinked between the two, improves PVA water resistance；Again with oxidant hydrogen peroxide, catalyst sulfuric acid ferrous iron, urea
Oxidative degradation and hydrophobically modified are carried out to it, to reduce the viscosity of glue, its solid content and water resistance is improved, it is good to obtain hydrophobic performance
And the PVA glues of good combination property, it is good to the hydrophobically modified effect of timber；Using sorbester p18 as emulsifying agent, using potassium peroxydisulfate to draw
Agent is sent out, using methyl methacrylate as monomer, emulsion polymerization is carried out with paraffin wax emulsions, obtains complex emulsions waterproofing agent, use it for
Improve the water imbibition and dimensional stability of timber.By modified PVA glue and modified starch, complex emulsions waterproofing agent, styrene-acrylic emulsion, draw
Hair agent potassium peroxydisulfate blending compounding obtains based Wood Adhesives.
