Description
Technical field
The invention belongs to timber treatment technology fields, and in particular to a kind of to improve wood preservation using cinnamylaldehyde derivatives
The treatment process of energy.
Background technique
Woodwork especially wood artwork is applied more and more extensive in daily life, and timber is a kind of natural organic
Material has apparent 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
Be in the prior art needed for technical problems to be solved, it is most to the processing of the raising of the preservation of timber against decay performance in the prior art
It is handled using bacteriostatic agent, improves wood preservation performance to reach, still, existing bacteriostatic agent the application is anti-in raising timber
While rotten performance, the threat of health can be also generated to contactee, does not meet friendly process, meanwhile, anti-corrosion effect is being handled
Initial stage is more high, but extension at any time, quickly reduces.
The better performances such as the antibacterial of cinnamic acid, anti-corrosion, thus its is very widely used, still, the antibacterial duration is shorter,
It is higher to the fungistatic effect turnover rate after treating of wood.
Summary of the invention
The purpose of the present invention is being directed to existing problem, provide a kind of using cinnamylaldehyde derivatives raising wood preservation
The treatment process of energy.
The present invention is achieved by the following technical solutions:
A kind for the treatment of process improving wood preservation performance using cinnamylaldehyde derivatives, by cinnamylaldehyde derivatives and deionization
Water is hybridly prepared into the cinnamylaldehyde derivatives solution that mass fraction is 3.5-4.5%, then adds into cinnamylaldehyde derivatives solution
Then the nano zinc oxide particles of its quality 0.12-0.16% use ultrasonication 3-5min, obtain premixed liquid, timber is soaked
It steeps in premixed liquid, at normal temperature, impregnates 5-10min, the dinaphthalene that mass fraction is 10-15% is then added dropwise into premixed liquid again
Phenol solution, the dinaphthalene phenol solution dripping quantity is the 20-30% of premixed liquid volume, and after being added dropwise, then premixed liquid and timber are moved
Enter in vacuum reaction kettle, at 75-80 DEG C, carries out vacuum impregnation and handle 10-15min, then take out, carried out using deionized water
Then surface clean drains naturally.
Further, the cinnamylaldehyde derivatives the preparation method comprises the following steps:
(1) 0.0035mol threonine and 0.0035mol sodium hydroxide are dissolved in the anhydrous methanol of 30mL at 80 DEG C, with
550r/min revolving speed stirs 2 hours, and then cooled to room temperature, filtering remove solids, obtain solution A；
(2) step (1) obtained solution A is kept the temperature at 60 DEG C 20min, the table of its quality 2% is then added into solution A
Face activating agent obtains solution B after mixing evenly；
(3) solution B made from step (2) is added in reaction kettle, is passed through nitrogen, excluded air, be preheated to 40 DEG C, to
The cinnamic acid of 0.0030mol is added dropwise in solution B, is dripped off in 30min, then proceedes to heat preservation 2 hours, then be filtered, uses
Dehydrated alcohol is washed, dry, crush, cross 120 mesh to get.
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 degree is -0.03MPa.
After the present invention has the advantage that present invention process processing timber compared with prior art, have to fungi with mould
There is significant inhibitory effect, is configured to cinnamylaldehyde derivatives solution by using cinnamylaldehyde derivatives, cooperates with the nano oxygen of addition
Change zinc particles and premixed liquid is made to timber progress immersion treatment, 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 is increased significantly to the bacteriostasis property tool of wood surface tissue, meanwhile, using premixed liquid pair
After timber impregnates, 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 combines, and under conditions of vacuum impregnation, permeates to wood internal, passes through the bridge of dinaphthol
Effect, combines the cinnamylaldehyde derivatives particle of wood internal with wood internal histocyte, thus greatly
The phenomenon that reducing cinnamylaldehyde derivatives extension at any time and being lost, and then not only effectively raise the preservation of timber against decay
Can, meanwhile, extend the wood preservation time.
