Description
Technical field
The present invention relates to wood processing technique fields, and in particular to a kind of system of nanofiber enhancing wood composite battenboard
Preparation Method.
Background technique
The main problem that the aspect of China's timber processing at present faces is exactly sharply reducing and the market demand for timber resources
It dramatically increases.China's afforestation rate is 18.21% now, occupies the 130th, the world, just corresponds to world average level
61.53%, national 1.75 hundred million hm2 of area of woods, per capita area are 0.132hm2, occupy the 134th, the world, per capita
Forest reserves is 9.048m3, only the world per capita accumulation 1/8.China's Forest Resources poor structure is felled using not
Just.Since ratio is very few in the existing forest reserves in China for coniferous forest, to make processing and utilization and the forest of timber
The sustainable development of resource is more difficult.In the age-area structure of the current Timber stands in China, young growth age is bigger than normal, so that in the recent period may be used
On the low side for felling the forest reserves that utilize, in addition to this, the huge population of quick economic development and China increases, and will all make me
State will all face the resource close quarters situation that supply falls short of demand in the long term.
In order to alleviate this imbalance between supply and demand, the forest reserves are saved, unnecessary waste is reduced, develop fast growing wood, rationally benefit
It is the key that solve the above problems with brush wood, small dimension wood.Poplar is important one of the fast-growing reproducting tree species in China.In recent years,
It is all cultivating extensively in many places.Since people lack comprehensive and systematic understanding to poplar, so that developing and utilizing poplar money
While source, and poplar resource is made to be seriously damaged and waste.Therefore first for active development and scientific utilization poplar resource
First will be from the characteristics of poplar resource, i.e., according to the property of poplar wood, the purpose utilized is established poplar comprehensive utilization, is opened
The multi-level processing of exhibition and the development and utilization policy based on practical technique.Poplar not corrosion resistant, dry easy to crack, the tension wood in poplar
Veneer can be made warp, bending and cracking occur, be difficult to replace naturally being directly used in wood structures through the high-quality timber of grade greatly, it is difficult
To meet the intensity requirement of structure material.
Summary of the invention
It is an object of the present invention in view of the above shortcomings of the prior art, propose a kind of nanofiber enhancing wood composite
High-intensitive composite laminboard can be made up in the preparation method of battenboard, this kind of method of poplar.
A kind of preparation method of nanofiber enhancing wood composite battenboard proposed by the present invention, including following preparation step
It is rapid:

S2, nanofiber implantation: using industrial sewing machine by the Wooden veneer after nanofiber implantation drying, Nanowire is obtained
Tie up veneer；
S3, plasma surface treatment: the nanofiber veneer is placed in the cold plasma handling system feeding web of normal pressure
On, two electrode Kun spacing are adjusted, nanofiber veneer surface and electrode spacing are 0.4-0.6mm, open power supply, regulation power,
So that plasma forms one layer of plasma curtain, nanofiber veneer is made to pass through electric discharge with the speed of 10-12m/min
Electrode carries out two-sided cold plasma processing to nanofiber veneer；
S4, dipping gluing: the nanofiber veneer after plasma treatment is immersed in 10-15min in melamine resin；
S5, room temperature are dried: the nanofiber veneer after dipping being carried out hang airing, the suspension time is 10-20min；
S6, drying: the nanofiber veneer that room temperature is dried is put into baking oven and is dried；
S7, assembly: 4-6 block nanofiber veneer is stacked as one group as core plate, core plate stacks Wooden veneer in two sides up and down again
Carry out assembly；
S8, hot pressing: the good plate of assembly is put into a press and carries out hot pressing to get a kind of nanofiber enhancing wood composite folder is arrived
Core plate.
The present invention provides a kind of nanofibers to enhance wood composite battenboard, mainly uses nanofiber and board using poplar board
It is compound, by being implanted into fiber line on board using poplar board surface, the physical and mechanical property of plate is improved, board using poplar board structure list is strengthened
Member, by laminar composite principle of compositionality combination chopped strand application of mixture theory, to the physical mechanics property of poplar laminated veneer lumber
It can be carried out enhancing, widen the use scope of poplar, to save timber resources, alleviate the contradiction of timber supply and demand anxiety.
Further, nanofiber described in S2 is glass fibre, carbon fiber, basalt fibre, aramid fiber and height
One or more of modules polyethylene fibre.
Further, the distance between nanofiber being implanted in S2 is 5-7mm.
Further, the plasma treatment in S3 using glow discharge plasma, dielectric barrier discharge plasma and
One of corona discharge plasma.
Further, the plasma treatment power in S3 is 4.0-4.5kw, handles time 25-45s.
Further, the plasma treatment gas in S3 is NH3, N2, O3.
Further, the melamine resin in S4 is melamine-urea-formaldehyde resin, phenol-melamine
One of amine-formaldehyde resin, phenol-urea-melamine formaldehyde resin, urea-phenol-melamine formaldehyde resin or
Person is a variety of.
Further, the dipping spread in S4 is 360-400g/m2.
Further, the drying temperature in S6 is 103-105 DEG C, time 10-15min.
Further, the hot pressing temperature in S8 is 127-130 DEG C, hot pressing time 10-15min.
A kind of preparation method of nanofiber enhancing wood composite battenboard of the invention, this method pass through in board using poplar board
Surface be implanted into glass wire, using veneer glass implantation and densification composite strengthening technology, improve the physical mechanics of plate
Performance strengthens board using poplar board structural unit, by laminar composite principle of compositionality combination chopped strand application of mixture theory, to poplar
The physical mechanics property of laminated veneer lumber can be carried out enhancing, widen the use scope of poplar, to save timber resources, alleviate timber
The contradiction of supply and demand anxiety；Can be structurally-modified to the progress of veneer surface by Surface Treatment with Plasma, and then in later period hot pressing,
It can make more abundant, the whole mechanical strength and bending resistance after further reinforcing pressing of bonding pressing between each veneer.
