Description
Technical field
The invention belongs to timber fields, and in particular to a kind of preparation method of insect prevention timber.
Background technique
The high molecular material that timber is made of cellulose, hemicellulose and lignin, and there is beautiful texture, color day
So, the advantages that texture is comfortable, plasticity is good, easy to process, thus by the ideal material as construction and decoration and Furniture manufacture.Its
Interior is the natural place of pest oviposition and breeding containing nutriments and moisture such as soluble sugar point, starch, but timber is due to length
Phase contacts with oxygen, light, moisture, is easy to be eaten by entomogenous fungi and lose, this will significantly limit the application effect and application field of timber.Cause
This, timber before use, appropriate insect-proof agent is often selected to carry out protective treatment, will play the good foxiness, mould of delaying
Change and other effects.However, most of traditional wood preservation from decay agent makes environment and the mankind containing harmful components such as heavy metal, formaldehyde
With great potential hazard will be caused.
Currently, the method for wood preservation from decay processing mainly has infusion process, diffusion method, hot and cold bath method and fumigating system, wherein impregnating
Method is most widely used, it, which refers to, is immersed directly in timber in insect prevention solvent, and insect-proof agent penetrates into wood internal.This method
The advantages of be that timber integrally can rapidly absorb mould proof solvent, but subsequent also need to be dried and will lead to a part of medicament
Loss, cause insect resistant effect poor, and pollute the environment.
Summary of the invention
The technical problems to be solved by the invention: being lost for medicament is easily led to during current wood preservation from decay, reduces anti-
Worm effect, and the problem of pollute the environment, the present invention provides a kind of preparation methods of insect prevention timber.
In order to solve the above technical problems, the present invention is using technical solution as described below:
A kind of preparation method of insect prevention timber, this method comprises the following steps:
(1) it takes timber to be immersed in ammonium bicarbonate soln, and is stood at 20~25 DEG C, take out the timber after impregnating, put
Enter dry at 60~65 DEG C timber after collection is dry, the timber after drying is put into coagulation liquid and is impregnated, carries out level-one
Handle 1~3h；
(2) after coagulation, timber is taken out, and natural drying obtains coagulation timber, and coagulation timber is complete
For complete immersion in two stage treatment liquid, the pH value for adjusting two stage treatment liquid is 8.5~9.0, and oscillation second level is carried out at 70~75 DEG C
Handle 1~2h；
(3) timber is taken out after vibrating two stage treatment, then be fully immersed in tertiary treatment liquid, adjust the pH for the treatment of fluid
Value 4.5~5.0 is warming up to 80~90 DEG C, 1~2h of isothermal holding, Geniposide is being added, additional amount is timber in tertiary treatment liquid
The 0.2~0.4% of quality is warming up to 100~105 DEG C, keeps the temperature 2~4h of tertiary treatment；
(4) it after keeping the temperature tertiary treatment, is cooled to room temperature, timber is taken out, be placed under ultraviolet lamp and be irradiated
30~50min, then natural drying can obtain insect prevention timber.
In the step (1) coagulation liquid be formulated as by medical PVA, water and fatty alcohol polyoxyethylene ether by
Mass ratio 3:8~9:0.6 is heated at 95~98 DEG C, collects heating mixture, and heating mixture is stored in 96 DEG C
In to get coagulation liquid.
Two stage treatment liquid is formulated as mixing different rosemary glycoside, acetone 1:3 in mass ratio in the step (2)
It closes to get two stage treatment liquid.
Tertiary treatment liquid is formulated as furfural, 2 hydroxy ethylamine and water 2~4:0.3 in mass ratio in the step (3)
~0.5:9 is uniformly mixed to get tertiary treatment liquid.
The present invention is compared with other methods, and advantageous effects are:
The present invention, first by the way that timber to be immersed in ammonium bicarbonate soln, makes carbon during preparing insect prevention timber
Sour hydrogen ammonium is adequately infiltrated to wood internal, then is heated, and ammonium hydrogen carbonate is decomposed during heating, is expanded in timber
The gap in portion increases subsequent raw material to the wetting property of timber, while what is generated can carry out sterilization and micro- to wood internal
The effect for measuring bleaching, is then handled timber using coagulation liquid, passes through fatty alcohol polyoxy second in coagulation liquid
Alkene ether improves medical PVA to the wellability of timber, while the processing of early period also improves leaching of the polyvinyl alcohol to timber
Profit, wraps up polyvinyl alcohol more fully to wood internal, then contact of the timber with air recycles second level
It is sufficiently diffused to wood internal, and wood internal absorbed portion acetone by the different rosemary glycoside of acetone solution in treatment fluid,
The insect resistant effect of timber is improved, then by the processing of tertiary treatment, one side furfural is infiltrated to wood internal, with therein third
Ketone is contacted, while carrying 2 hydroxy ethylamine entrance, improves insect resistant effect, the effect on the other hand adjusted in the catalysis of soda acid
Under, promote furfural react forming furfural acetone resin with acetone, forms protective layer, and the Geniposide pair being added in wood surface
Wood internal is crosslinked, and further increases the insect resistant effect of wooden, insect prevention wood preservation from decay effect prepared by the present invention is good, to ring
Border pollution is small.
