Description
Technical field
The invention belongs to wood preservation technical field, and in particular to a kind of method of Calophyllum preservative treatment.
Background technology
Calophyllum, which becomes a useful person, needs more than 150-200, the expensive hardwood of generic name, is commonly called as the red wingceltis in Southeast Asia, and Calophyllum drying property is good
Good, not easy to crack and warpage, is the sound wood for making solid wood furniture, Calophyllum is high-end furniture woods, due to its texture
Color also referred to as small redwood close with rosewood class color and luster.Therefore the preservative treatment of Calophyllum is particularly important, it is necessary to anti-
Rotten agent meets permanent effective anti-corrosion effect.In the prior art, to the preservation of timber against decay, organic anti-corrosive agent is used mostly, although its
Permeance property in timber is excellent, but the anti-corrosion term of validity is shorter, it is impossible to meets the long-term corrosion-resistant needs of Calophyllum.
The content of the invention
In order to solve the above technical problem, the present invention provides a kind of method of Calophyllum preservative treatment.
The present invention is achieved by the following technical solutions.
A kind of method of Calophyllum preservative treatment, including following operating procedure:
(1)By weight, 15-22 parts of silver nitrates, 28-32 parts of sodium tungstates are added into 150-200 parts of deionized water, so
Afterwards thereto add 17-20 part monocrystalline silica flours, after being heated to 220-250 DEG C, when isothermal holding 2-3 is small after, centrifuge precipitated,
After precipitation is cleaned, Calophyllum preservative is made;
(2)By step(1)Obtained Calophyllum preservative is added into 90-95 times of water weighed of its weight, mix uniformly after, then to its
Middle addition Polyethylenimine, continues after stirring evenly, and maceration extract is made, and then using vacuum pressure impregnating method, Calophyllum is carried out
Impregnation;
(3)Step will be passed through(2)After the Calophyllum drying of processing, anti-corrosion Calophyllum is made.
Specifically, above-mentioned steps(1)In, the Average Particle Diameters of monocrystalline silica flour are 300 mesh.
Specifically, above-mentioned steps(1)In, precipitation cleaning way is:After being cleaned 2 times using deionized water, then using volume
The ethanol solution that fraction is 75% cleans 3 times, is finally cleaned 2 times using deionized water again.
Specifically, above-mentioned steps(2)In, the addition of Polyethylenimine is the 0.5-0.7% of water weight.
Specifically, above-mentioned steps(2)In, in vacuum pressure impregnating method, the vacuum of impregnating autoclave is 0.045MPa, impregnates and adds
The pressure of pressure is 0.74MPa.
Specifically, above-mentioned steps(3)In, the temperature of drying is 65-70 DEG C, when the time of drying is 10-12 small.
From the above technical scheme, it can be seen that the beneficial effects of the invention are as follows:
The method of Calophyllum preservative treatment provided by the invention, it is easy to operate, it is of low cost, in processing procedure, do not interfere with sea
The excellent properties of of Chinese bush cherry wood itself, but the antiseptic property of Calophyllum can be greatly lifted, and the anti-corrosion term of validity is grown, and is at least
10 years.The present invention uses inorganic corrosion inhibitor, its anti-corrosion term of validity is significantly higher than organic anti-corrosive agent, but in the prior art,
There is the defects of inorganic corrosion inhibitor poor permeability, therefore the present invention uses carrier of the monocrystalline silica flour as inorganic corrosion inhibitor, into
And the permeability of inorganic corrosion inhibitor is effectively lifted, improve the antiseptic property of Calophyllum;Wherein, the addition of Polyethylenimine, can
Further to lift adhesive rate of the inorganic corrosion inhibitor inside Calophyllum, and then improve corrosion-resistant effect;The present invention is made
Wolframic acid silver preservative, there is extremely excellent bactericidal property, and the phenomenon for being not susceptible to degrade or failing.
