Description
Technical field
The invention discloses a kind of bamboo wood preparation method of anti-current mistake type mould inhibitor, belong to mould inhibitor technology of preparing neck
Domain.
Background technology
As the rapid growth and the people of China's economy are pursued the stratification high lived, demand and day of the society to timber
It is all to increase.But China's timber resources is poor, but bamboo resource relative abundance, second forest reserves are described as, its area and yield
Occupy first place in the world, however, because bamboo growth is fast, cause that the content of its fibrocyte is few, parenchymal tissue is more.Secondly, bamboo wood
It is hydrophilic material, thus bamboo wood is in wet environment, during storage, transport and use, it is easy to which generation is gone mouldy, becomes
Color, damage by worms and the rotten processing that have impact on bamboo wood with utilize.Therefore, bamboo wood fungus-proof antisepsis are treated as bamboo wood industrialized utilization not
Can missing link, the sustainable use for bamboo timber resource is most important.
The going mouldy of bamboo wood and timber, worm stays substantially similar with rotten biological mechanism and Biochemical processes, and bamboo
Material and wood chemical compositions also have similitude with infringement bacterium.Therefore, bamboo wood can be referred from traditional wood preservation with anti-agent suddenly
Agent.But bamboo mould-proof agent can not mechanically apply mechanically wood preservation medicament, traditional timber preservative is continued to use completely can be brought
A series of problems, such as environmental problem, adaptability of medicament.Current bamboo wood is often generally divided into fumigant type antifoggant, oils with mould inhibitor
Anti- clouds agent, oil soluble（Carry）Mould inhibitor and water-soluble（Carry）Mould inhibitor.But existing fumigant type antifoggant, the anti-clouds agent of oils, oil soluble
（Carry）Mould inhibitor and water-soluble（Carry）Mould inhibitor is poor to the anchorage of bamboo wood, is easy to run off, and storage time is short, and easily by microorganism point
Solution, it is impossible to long term, causes bamboo wood mildew resistance to be lost in serious, it is impossible to long duration of action, so preparing a kind of bamboo wood anti-current
Mistake type mould inhibitor is necessary.
The content of the invention
Present invention mainly solves technical problem：It is poor in the presence of the anchorage to bamboo wood for existing bamboo mould-proof agent, easily
It is lost in, storage time is short, and is easily decomposed by the microorganisms, it is impossible to the problem of long term, there is provided a kind of carboxymethyl-modification ring
Dextrin wraps up lysozyme, is infiltrated into inside bamboo wood by the cyclodextrin of carboxymethyl-modification, while lysozyme effectively decomposes attachment
In the fungal cell film of bamboo material surface, prevent it from growth and breeding, the method for improving bamboo wood fungicidal properties, the present invention is pasted by ring
Smart and chloroacetate reaction is simultaneously grafted carboxymethyl group, improves the affine performance of cyclodextrin and bamboo wood, while lysozyme is dispersed to
In phosphate buffer, lysozyme is wrapped up by cyclodextrin and coagulant liquid is compounded to form with Ludox, after enhancing mould inhibitor solidification with
The fixation performance of bamboo wood, the effectively fungicidal properties of enhancing bamboo wood, with wide prospect of the application.
In order to solve the above-mentioned technical problem, the technical solution adopted in the present invention is：
（1）Choose 9~10g beta-schardinger dextrins to be placed in beaker, add the ammonia spirit of 25~30mL mass fractions 10%, stirring mixing

L chloroacetic acid solutions, control time for adding for 65~70min, after being added dropwise to complete, 3~5h of insulation reaction；
（2）After the completion for the treatment of insulation reaction, pH to 9.5 is adjusted with glacial acetic acid solution, stands 25~30min, collect mixed liquor simultaneously
Mix with the stirring of 1000mL methyl alcohol, filtered after still aging 6~8h and collect filter cake, 2~3h is vacuum dried at room temperature, mill
Modified beta-schardinger dextrin powder is prepared into, it is standby；
（3）25~30mg lysozymes, 10~15g sodium dihydrogen phosphates, 5~8g disodium hydrogen phosphates is chosen to be placed in 1L volumetric flasks, plus
After water is settled to 1000mL, then 25~30min is stood at room temperature, be prepared into lysozyme dispersion liquid；
（4）Choose 0.2~0.5g steps（2）The modified beta-schardinger dextrin powder for preparing is placed in 200~300mL0.03~0.05mol/
In L calcium chloride solutions, after 1~2h of stirring mixing, ion chelating liquid is prepared into, then by volume 1:1, by the molten of above-mentioned preparation
Bacterium enzyme dispersion liquid mixes with the stirring of ion chelating liquid, and 2~3h of mixing is stirred at room temperature；
（5）After the completion of mixing to be mixed, collect mixed liquor and be placed in the bag filter of interception 3500,10~12h of dialysis treatment,
Dialyzate is collected to obtain, then is counted by weight, 10~15 parts of dialyzates, 25~30 parts of tetraethyl orthosilicates and 65~80 are weighed respectively
Part ethanol solution of mass fraction 65% is placed in beaker, 10~15min of ultrasonic disperse under 200~300W, you can be prepared into one kind
Bamboo wood anti-current mistake type mould inhibitor.
Application process of the invention：Choose the above-mentioned preparation anti-current mistake type mould inhibitors of 100~200g and 500~600mL water is mixed
Merging is placed in spray gun, and mould proof bamboo material surface needed for being sprayed under 5~10MPa, control anti-current mistake type mould inhibitor makes
Consumption is 100~150g/m2, it is to be sprayed after the completion of, stand and make it to dry naturally, you can complete bamboo wood material mould proof place
Reason.
