Abstract
The invention discloses the preparation method of a kind of inorganic wheat straw flakeboard in sheet material field, comprise the steps: 8 parts of polyvinyl alcohol and 92 parts of water mix homogeneously, put into heating 1h in reactor；In reactor, add 4 parts of magnesium chlorides, 6 parts of magnesium oxide, 3 parts of sodium silicate, 7 parts of sodium phosphates and 5 parts of ferrous sulfate again, stir 30-40min by homogenizer, obtain the thick inorganic adhesive of milky；Inorganic adhesive and wheat straw particle in mass ratio 3: 1 are inserted in periodic blender and is sufficiently stirred for 4-9min, after mating formation into the slab that thickness is 50-70mm, send into cold press locked mode, pressurize 48h, demoulding maintenance 7 days；It is 10-30% by the drying baker of the slab feeding 80 DEG C after maintenance is dried to moisture content, obtains inorganic wheat straw flakeboard.The inorganic wheat straw flakeboard that the present invention prepares, production cost is low, it is achieved that the utilization to straw, saves timber resources.
Description
Technical field
The invention belongs to sheet material field, be specifically related to a kind of inorganic wheat straw flakeboard.
Background technology
Inorganic wheat straw flakeboard be with wheat straw particle for strengthen phase, inorganic adhesive as matrix material and auxiliary it
In a small amount of additive, through the inorganic artificial board of straw of one prepared by cold moudling, have fire prevention, high-strength,
The many merits such as insect protected, prosthetic free formaldehyde release, alternative wood-base fibre and particle panel material is widely used in furniture
The fields such as manufacture, interior/exterior decoration.China is large agricultural country, and agricultural crop straw annual production reaches more than 700,000,000 ton,
Wherein most is incinerated or discarded, does not embody its proper value, but also pollutes the mankind and depend on for existence
Ecological environment.The agricultural crop straw such as Caulis et Folium Oryzae, wheat straw also has abundant cellulose, can serve as artificial former
Material.At present, utilize straw-based panel to produce the expensive isocyanates of main employing etc. to have
Machine adhesive, production cost is high, and therefore development is seriously restricted.Nervous big of current timber resources
Under background, agricultural wastes can be turned waste into wealth by development straw-based panel industry, saves timber money
Source, economic and social benefit is notable.
Summary of the invention
It is an object of the invention to provide the preparation method of a kind of inorganic wheat straw flakeboard, reduce production cost,
Achieve the utilization to straw, save timber resources.
The object of the present invention is achieved like this: the preparation method of a kind of inorganic wheat straw flakeboard, including such as
Lower step:
1) by 8 parts of polyvinyl alcohol and 92 parts of water mix homogeneously, heating 1h in reactor is put into；
2) in reactor, 4 parts of magnesium chlorides, 6 parts of magnesium oxide, 3 parts of sodium silicate, 7 parts of sodium phosphates and 5 are added again
Part ferrous sulfate, stirs 30-40min by homogenizer, obtains the thick inorganic adhesive of milky；
3) inorganic adhesive and wheat straw particle in mass ratio 3: 1 are inserted in periodic blender it is sufficiently stirred for
4-9min, sends into cold press locked mode, pressurize 48h, the demoulding after mating formation into the slab that thickness is 50-70mm
Maintenance 7 days；
4) slab after maintenance is sent into that to be dried to moisture content in the drying baker of 80 DEG C be 10-30%, obtain inorganic
Wheat straw flakeboard.
As a further improvement on the present invention, described step 3) in the specification of wheat straw particle be distributed as 1mm
Hereinafter account for 10.7%, 1-3mm accounts for 35.4%, 3-5mm accounts for 43.1%, 5-10mm accounts for 8.3%, more than 10mm
Account for 1.5%.
As a further improvement on the present invention, periodic blender mixing time is 6-7min, slab thickness
Mat formation for 60mm.
As a further improvement on the present invention, described step 4) in slab be dried to moisture content be 20%.
Compared with prior art, the beneficial effects of the present invention is: by using inorganic adhesive, reduce
The production cost of wood-based plate, it is to avoid use the organic adhesion agents such as expensive isocyanates so that profit
It is possibly realized with straw making artificial plate.The inorganic wheat straw flakeboard that the present invention prepares, wheat straw particle is at plate
Distributing homogeneity in material increases, and interface performance is good, and interface friction resistance is big, sheet material mechanical property
Improving, heat stability increases；Inorganic wheat straw flakeboard density increases, between inorganic adhesive each crystalline phase granule
Interaction enhanced.Inorganic wheat straw flakeboard has fire prevention, high-strength, insect protected, prosthetic free formaldehyde
The many merits such as release, alternative wood-base fibre and particle panel material is widely used in the neck such as Furniture manufacture, interior/exterior decoration
Territory.
