Description
Technical field
The invention belongs to wood processing technique field, be specifically related to a kind of timber does old processing method.
Background technology
Style of missing old times or old friends at present is as one way of life fashion, the sentiment of a kind of culture, the recurrence of a kind of soul of recovering one's original simplicity,
Being welcome by more and more people, people thirst for household and distribute vicissitudes sense and sense of history, feel heavy cultural deposits, and timber does
It is close true that people are deferred in the exploration of old technology method just, pursues the demand of peaceful life and carries out, has far-reaching reality
Meaning.
Existing timber does the methods such as old master's quick lime to be used immersion, paint and processes, and processes the time long, and technique is multiple
Miscellaneous, relatively costly, and the wood surface after process is dirtier, need to repeatedly wipe and just can carry out late stage process process.Also adopt
Processing timber with potassium permanganate, mainly carry out carbonization process, after it processes, timber black and white contrast is big, and effect is less certainly
So.Additionally, existing do old disposal methods after Wood mechanical property etc. can be subject to bigger infringement, normal environment temperature when using
Difference is relatively big also can be to doing old effect and timber exerts an adverse impact.
Summary of the invention
It is desirable to provide a kind of timber do old processing method, have do old high treating effect, process after timber
The feature of excellent performance.
The present invention is achieved through the following technical solutions:
A kind of timber do old processing method, comprise the steps:
(1) do old treatment fluid to prepare:
1) weigh following material by weight: 1 ~ 2 part of nano-carbon powder, 1 ~ 3 part of nano-cobalt powder, 2 ~ 4 parts of modified urea-formaldehyde resins, 1 ~ 3
Part agar, 2 ~ 4 portions of Bufo siccus grass, 3 ~ 4 portions of Rhizoma Menispermis, 2 ~ 5 portions of Radix Picriae felterrae, 1 ~ 2 portion of Cortex Meliae, 1 ~ 3 portion of Radix Peucedani, 7 ~ 10 portions of vegetations
Ash, 2 ~ 4 parts of calcium chloride, 5 ~ 8 parts of potassium permanganate, 300 ~ 350 parts of water；
2), after being mixed homogeneously by the clear water of Bufo siccus grass, Rhizoma Menispermi, Radix Picriae felterrae, Cortex Meliae and Radix Peucedani with its gross mass 4 times, boiling water is decocted
Boil 30 ~ 40min, filter and concentrate the filtrate to original volume 1/3 after, obtain extracting solution standby；
3) 2 being operated) extracting solution and modified urea-formaldehyde resin, the agar that prepare jointly puts into and weighs in standby water, and heating is protected
Holding solution temperature is 43 ~ 48 DEG C, after being stirred continuously uniformly, then by nano-carbon powder, nano-cobalt powder, plant ash, calcium chloride and Gao Meng
Acid potassium is put into jointly, is finally stirred until homogeneous to do old treatment fluid with the rotating speed of 1800 ~ 2000 revs/min standby；That adds receives
Rice carbon dust and cobalt powder, can well be filled in the lines that board surface etching produces, can not only visually improve do old
Whole structure, can also strengthen plank to worm, mould isolation effect simultaneously, and then improve antibacterial, crack resistence, the wearability of plank
Energy；
(2) the pre-dry-cure of timber:
Timber to be processed is put into hothouse, be dried to water content be after 15 ~ 20% standby；
(3) high temperature coating processing:
Continuing to be placed in hothouse by the timber after step (2) pre-dry-cure, step (1) prepared does the atomization spray of old treatment fluid
Being sprinkled upon on wood surface, keeping the temperature in hothouse is 65 ~ 70 DEG C, when the water content of timber reduces to 10 ~ 15%, further
Secondary will do old treatment fluid atomized spray on wood surface, continuing to keep the temperature in hothouse is 65 ~ 70 DEG C, treats the water of timber
Content reduces after 10 ~ 15% standby；
(4) low temperature coating processing:
By step (3) process after timber take out, will do old treatment fluid atomized spray on wood surface once after, then by wood
Material is put in freezer dryer, is dried after freezing 3 ~ 5min, and being dried to water content is to take out after 3 ~ 5%, will do old again
Timber, on wood surface, is then put in freezer dryer by treatment fluid atomized spray, then does after freezing 4 ~ 6min
Dry, being dried to water content is to take out after 3 ~ 5%, is put under normal temperature condition standing 2 ~ 3h.Coat through high temperature coating and low temperature
After integrated treatment, the combination of the surface etch layer of timber effective ingredient with wood internal itself by doing old treatment fluid more steps up
Close, in the case of the temperature difference is relatively big, remain to keep preferably stability in use, surface layer abrasion-proof, resistance to contraction, the most easy to crack, promote
Do old stability.
Further, the preparation method of the modified urea-formaldehyde resin described in step (1) is: formed sediment with Semen Maydis by Lauxite
After powder, Polyethylene Glycol, glycerol mix according to mass ratio 15:2:2:1, keeping temperature is 60 ~ 70 DEG C, with 2000 ~ 2500 revs/min
The rotating speed of clock i.e. obtains modified urea-formaldehyde resin after being stirred until homogeneous.Modified Lauxite has receipts the most water-fast, ageing-resistant, resistance to
Contracting performance, dipping adhere to board surface fiber after, its surface characteristic can be improved very well, promote its persistency doing old effect and
Stability.
Further, the granular size of the nano-carbon powder described in step (1) is 30 ~ 40nm, and the granule of nano-cobalt powder is big
Little is 50 ~ 60nm.
Further, the temperature being dried described in step (2) is 45 ~ 50 DEG C.
Further, temperature time freezing in the freezer dryer described in step (4) is-8 ~-12 DEG C, pressure when being dried
Power is 10 ~ 15Pa.
There is advantages that
(1) present invention does old treatment fluid and has alkalescence, can have certain corrosiveness to board surface, the Bufo siccus grass of interpolation,
Rhizoma Menispermi, Radix Picriae felterrae, Cortex Meliae, Radix Peucedani medicinal herb components can penetrate into inside plank, strengthen its antibacterial, insect protected performance, interpolation
Modified urea-formaldehyde resin has good shrinkage water-fast, ageing-resistant, resistance to, can nano-carbon powder and nano-cobalt powder be bonded and fixed at
Board surface, the collocation of two kinds of nano-particle uses to improve does old color and luster and effect, can promote again the wearability of plank and do
Old persistency, moreover it is possible to improve slickness and the feel of board surface, improve its anti-cracking performance.
(2) when timber being done old process, having set up high temperature coating separately and low temperature has coated two stages, at high temperature coating
Reason can strengthen does the intensity that old treatment fluid penetrates into and acts on, and the crackle that low temperature coating processing can improve wood shrinkage generation very well is existing
As, strengthen its stability used at low temperatures, under two stage common effect, the treatment effect doing old treatment fluid obtains very
Good lifting, use value and the effect of timber are the most lasting.
(3) each step of the present invention arranges rationally, and under its common mating reaction, the timber after process has simple and unsophisticated outmoded
Vicissitudes sense, condition is the most true to nature, and its smooth surface, wear-resisting, remains to keep excellent doing under the use environment that the temperature difference is bigger
Old condition and use value, great dissemination.
