Description
Technical field
The invention belongs to Wood Science and Technology field, and in particular to a kind of preparation method of fire-retardant oriented wood chipboard.
Background technology
With increasingly being highlighted the problem of global warming, exceedingly odious weather takes place frequently, with " low emission, low stain, low energy
The low-carbon economy that consumption " is the theme increasingly is approved and praised highly by people.Under such background condition, wood industry is all with life using it
" green ", " environmental protection ", the characteristic of " cleaning " come, in development low-carbon economy, reply climate change, just playing and becoming more and more important
Effect.Timber and woodwork have good carbon sequestration effect.As long as without putrefaction, not burning, the carbon sequestration function of timber and woodwork
Will for a long time, stably it continue.Some carbon sequestration times are up to decades, centuries.Therefore, increase timber to use, and to the greatest extent
The service life of prolonging wood and woodwork is measured, it is significant to reduction energy consumption, increase emission reduction.According to measuring and calculating, forest often gives birth to
1 ton of timber is produced, can averagely fix carbon dioxide 1470kg, release oxygen 1070kg.
Oriented wood chipboard is to be set with fresh path woods, a deforestation, reel etc. for raw material by special in existing sheet material
It is standby to be processed into the wood shavings that 40-100mm is long, 5-20mm is wide, 0.3-0.7mm is thick, through drying, applying glue, orienting spreading, continuous hot-press into
A kind of oriented structure sheet material made of the techniques such as type.It has extremely strong anti-folding bending strength, high dimensional stability, green
Environmental protection, stablize it is indeformable, thus be widely used in house construction, building template, interior/exterior decoration, timber manufacturing industry, packaging,
The industries such as floor base material, finished product Furniture manufacture, facilities for transport and communication.
After " 911 " event, the development and application of applied fireproofing is more paid attention in countries in the world, to tackle anti-probably fire prevention peace
Full demand.At present, Japanese fire-retardation artificial board manufacturing enterprise accounts for more than the 15% of industry and enterprise sum more than 30；The U.S. is fire-retardant
Wood-based plate annual production reaches 100 ten thousand steres, is mainly used in industrial building, commercial building, utilities building and family's Folk House Construction
In.It is due to the developed country such as Europe, North America, Japan caused by cigarette and toxic gas suffocate to have 80% in fire fatality accident
In recent years research, selection, evaluation fire retardant fire resistance when, focus more on the smoke-suppressing of fire retardant and fire proofing and low
Toxicity.The compound containing elements such as molybdenum, iron, copper, zinc is added in fire retardant, flue gas is reduced and produces.Lost from Chinese Central Television (CCTV) new address
After fire and Chengdu bus combustion incident, China more payes attention to the safety problem of fire safety and public place, newly revises
《Fire service law》Mandatory provision has been done using the flame retardant rating of material to public place with national standard GB20286.China hinders at present
The trend of combustion technology development is developed from the fire retardant of single component to Recompounded multielement fire retardant, from single flame retardant efficiency to one
Multiple-effect, there is environmental protection, low toxicity, the multifunctional efficient flame-retarded technology direction of low cost to develop.Therefore in order to meet people to sheet material
Demand for security, the present invention provides a kind of oriented wood chipboard with fire resistance.
The content of the invention
It is an object of the invention to provide a kind of preparation method of fire-retardant oriented wood chipboard.
To reach above-mentioned purpose, the present invention uses following technical scheme：
A kind of preparation method of fire-retardant oriented wood chipboard, comprises the following steps：
1) oriented wood chipboard is put into high-pressure impregnation tank, high-pressure impregnation tank is then evacuated to 650-700mm mercury column,
Keep 25-35min；
2) retardant solution is added in the high-pressure impregnation tank, is then slowly forced into 1.0-1.2MPa, keep 8-
10min；
3) pressure in step 2) is released, discharges retardant solution；Take out the oriented wood chipboard in impregnating autoclave and dry, will
The oriented wood chipboard dried obtains fire-retardant oriented wood chipboard in 60-80 DEG C of drying.
Further, the retardant solution refers to the aqueous solution of fire retardant, and the concentration of the retardant solution is 0.18-
0.24kg/L.Retardant solution concentration of the present invention is too low not to reach flame retardant effect, and excessive concentration not only increases cost, and can drop
Low oriented wood chipboard internal bond strength.
Further, fire retardant is nitrogen phosphorus series compound or borate family compound.
Further, in step 3), not only energy consumption is excessive for the oriented wood chipboard after convection drying dipping, and easily causes plate
Material deforms；Therefore simultaneously naturally dry to moisture content is 30-50% to the oriented wood chipboard in present invention taking-up impregnating autoclave.
The moisture content of the fire-retardant oriented wood chipboard is 6-8%.
Further, in order that oriented wood chipboard can be completely infused in retardant solution, therefore using the fire-retardant of excess
Agent solution；Preferably, the mass ratio of the oriented wood chipboard and fire retardant is 1：2.0-3.0.
Fire retardant of the present invention can also use composition form, in the composition of fire retardant add flame retardant zinc oxide with
Permeability of the fire retardant in oriented wood chipboard is improved, so as to effectively improve the fire resistance of oriented wood chipboard；The present invention is hindering
Fire and crosslinking agent is added in the composition of agent, promote the gumminess of adhesive in oriented wood chipboard, so as to improve fire-retardant oriented shaving
The internal bond strength of plate, avoid the gumminess destroyed in dipping process in oriented wood chipboard.
Further, count in parts by weight, fire retardant includes following component：Borate family compound 1-5 parts, it is sub- to gather carbonization two
Amine crosslinker 3-4 parts, zinc oxide 3-6 parts.
Further, count in parts by weight, fire retardant includes following component：Nitrogen phosphorus series compound 2-4 parts, polycarbodiimide
Crosslinking agent 3-4 parts, zinc oxide 1-2 parts.
Further, in step 2), the slowly pressurization refers to be pressurizeed with 100-200Pa/min speed, so not
Only retardant solution is equably penetrated into oriented wood chipboard, and the delamination splitting of oriented wood chipboard will not be caused.
Further, the borate family compound is one kind in Firebrake ZB, ammonium pentaborate, kodalk and barium metaborate
It is or a variety of.
Further, the nitrogen phosphorus series compound is one kind in polyphosphoric acid melamine, ammonium polyphosphate and diammonium hydrogen phosphate
It is or a variety of.
It is further noted that if not otherwise specified, any scope described in the present invention includes end value and end value
Between any subrange for being formed of any numerical value and any number between end value or end value.
Beneficial effects of the present invention are as follows：
1st, it can realize that fire retardant quickly and evenly penetrates into the sandwich layer of oriented wood chipboard using the preparation method of the present invention,
So as to reach fire-retardant effect.
2nd, fire-retardant oriented wood chipboard is prepared using the method for the present invention, will not only changes this body structure of oriented wood chipboard
And characteristic, nor the adhesive dosage of oriented wood chipboard can be increased.
3rd, preparation method of the invention is simple, small investment, is not limited by region and place, it is possible to achieve industrialized production.
