Description
Technical field
The invention belongs to timber treatment technology field, and in particular to one kind improves wood preservation using cinnamylaldehyde derivatives
The handling process of energy.
Background technology
Woodwork especially wood artwork is applied more and more extensive in daily life, and timber is a kind of natural organic
Material, there is obvious biological nature, easily by biological attacks such as bacterium, worm, the raw drilling worms in sea.How the preservation of timber against decay performance is improved
It is required technical problems to be solved in the prior art, the processing of the raising to the preservation of timber against decay performance is most in the prior art
Handled using bacteriostatic agent, wood preservation performance is improved to reach, still, existing bacteriostatic agent the application prevents in raising timber
While rotten performance, the threat of health can be also produced to contactee, does not meet friendly process, meanwhile, its antiseptic effect is being handled
Initial stage is more high, but with the extension of time, it is quick to reduce.
The better performances such as the antibacterial of cinnamic acid, anti-corrosion, thus its application is very extensive, still, the antibacterial duration is shorter,
It is higher to the fungistatic effect turnover rate after treating of wood.
The content of the invention
The purpose of the present invention is to be directed to the problem of existing, there is provided one kind improves wood preservation using cinnamylaldehyde derivatives
The handling process of energy.
The present invention is achieved by the following technical solutions：
A kind of handling process that wood preservation performance is improved using cinnamylaldehyde derivatives, cinnamylaldehyde derivatives and deionized water are mixed
The cinnamylaldehyde derivatives solution for being configured to that mass fraction is 3.5-4.5% is closed, its matter is then added into cinnamylaldehyde derivatives solution
0.12-0.16% nano zinc oxide particles are measured, then using ultrasonication 3-5min, premixed liquid is obtained, timber is dipped into
In premixed liquid, at normal temperatures, 5-10min is soaked, the dinaphthol that then dropwise addition mass fraction is 10-15% into premixed liquid again is molten
Liquid, the dinaphthalene phenol solution dripping quantity is the 20-30% of premixed liquid volume, and after being added dropwise, then premixed liquid moves into true with timber
In empty reactor, at 75-80 DEG C, vacuum impregnation processing 10-15min is carried out, is then taken out, surface is carried out using deionized water
Cleaning, is then drained naturally, you can.
Further, the cinnamylaldehyde derivatives preparation method is：
（1）0.0035mol threonines and 0.0035mol sodium hydroxides are dissolved in 30mL absolute methanol at 80 DEG C, with 550r/
Min rotating speeds stir 2 hours, then naturally cool to room temperature, filter, and remove solids, obtain solution A；
（2）By step（1）Obtained solution A is incubated 20min at 60 DEG C, and the surface that its quality 2% is then added into solution A is lived
Property agent, after stirring, obtains solution B；
（3）By step（2）Obtained solution B is added in reactor, is passed through nitrogen, excludes air, 40 DEG C is preheated to, to solution
0.0030mol cinnamic acid is added dropwise in B, is dripped off in 30min, then proceedes to insulation 2 hours, then is filtered, use is anhydrous
Ethanol is washed, and is dried, and is crushed, and is crossed 120 mesh, is produced.
Further, the surfactant is neopelex.
Further, the nano zinc oxide particles granularity is 70-80nm.
Further, the ultrasonic power is 1000W, frequency 30kHz.
Further, in the vacuum impregnation, vacuum is -0.03MPa.
The present invention has advantages below compared with prior art：After present invention process processing timber, have with mould to fungi
There is significant inhibition, be configured to cinnamylaldehyde derivatives solution by using cinnamylaldehyde derivatives, cooperate with the nano oxygen of addition
Change zinc particles are made premixed liquid and carry out immersion treatment to timber, and cinnamylaldehyde derivatives particle can effectively penetrate into wood internal
In tissue, meanwhile, by the activity of nano zinc oxide particles, it can effectively carry cinnamylaldehyde derivatives particle and attach to timber
Surface is effectively combined, and the bacteriostasis property tool of wood surface tissue is increased significantly, meanwhile, using premixed liquid pair
After timber immersion, by the way that dinaphthalene phenol solution is added dropwise into premixed liquid, by the active function of dinaphthol molecule, can effectively with
Cinnamylaldehyde derivatives particle is combined, and under conditions of vacuum impregnation, is permeated to wood internal, passed through the bridge of dinaphthol
Effect, the effective cinnamylaldehyde derivatives particle for causing wood internal is combined with wood internal histocyte, so as to greatly
The phenomenon that cinnamylaldehyde derivatives are lost in the extension of time is reduced, and then not only effectively raises the preservation of timber against decay
Can, meanwhile, extend the wood preservation time.
