Background technology
Timber is widespread in nature, and it processes simple, is one of material that the mankind use earliest, therefore wooden text
Thing is one of most common historical relic in archaeology.Unearthed wooden cultural relic due to burying in underground, often containing a large amount of water for a long time
Point.Although surface is bright and new when being unearthed, due to being soaked for a long time in underground water, and decomposed by Soil Microorganism, in it
Rot in portion.Therefore, the dehydration shaping of waterlogged wooden culture relics is reinforced where the always heavy difficult point in wooden cultural relic protection field.
Although waterlogged wooden culture relics remain in that intact, its substantial internal polysaccharide component on the surface
(Cellulose and hemicellulose)Seriously degrade, cell wall structure is broken to can't bear, if before it is dried without appropriate dehydration
Consolidation process, will occur serious deformation, cracking and even damages.Traditional waterlogged wooden culture relics dehydration shaping reinforcement means includes
Alum method, sucrose method, resin method, polyethylene glycol method, alcohol ether connect leaching method and glyoxal method etc., but they have suction acid tide respectively
Solve, easily go mouldy, poor permeability, low intensity, strong toxicity the shortcomings of, therefore, still must be to explore better method and effort.
With flourishing for modern polymer science technology, synthesis polymer reactant is applied to historical relic more and more
Protection, specific in terms of waterlogged wooden culture relics protection.The use of synthesis macromolecule most efficient method is that monomer infiltration polymerize
Method, compared with the resin and polyethylene glycol of HMW, the monomer of small-molecular-weight is easier to penetrate into the inside of waterlogged wooden culture relics,
With more preferable penetration depth, processing time can be shortened;Compared with alum, sucrose, the polymer substance after polymerization has more preferable
Water proofing property and antibiotic property;Meanwhile, macromolecule modifiability is strong, can be easily modified as needed.But it is big
Many synthesis polymer reactants have ageing-resistant performance and the relatively poor weakness of water resistance, and reaction condition is relatively violent.Cause
This, is badly in need of finding a kind of method that water resistance is good, ageing-resistant performance is good to carry out being dehydrated anti-corrosion sizing consolidation process to historical relic.
The content of the invention
The technical problems to be solved by the invention:Synthesis height for being conventionally used to wooden cultural relic dehydration shaping consolidation process
There is provided a kind of preparation side of wooden cultural relic dehydration shaping strengthening agent for molecular agents water resistance and the shortcoming of loss of properties on aging
Method.
In order to solve the above technical problems, the technical solution adopted by the present invention is:
(1)The ripe bancoul nuts of 1~3kg are weighed, are placed under the sun after being exposed to the sun to bancoul nuts and splitting, through shelling, picking, wash,
Dry, crush and sieve, obtain sieving, sieving is placed in oil press, being 60~95 DEG C in temperature pushes expressed oil, obtains
To rough Oleum Verniciae fordii;
(2)Rough Oleum Verniciae fordii is filtered, filtrate is obtained, 400~500g filtrates and 300~400g Brazil waxs are steamed
Fry, will steam the material after frying is 1 in mass ratio with absolute ethyl alcohol:1~1:After 2 mixing, stratification obtains subnatant, by under
Layer liquid is distilled, and is removed absolute ethyl alcohol, is obtained wood wax oil;
(3)25~30g HMDOs are weighed to be added in three-necked flask, in temperature be 120~130 DEG C at backflow 40~
After 50min, then 25~30mL mass fractions are added dropwise for 35% phosphoric acid solution, 3~4h of stirring reaction, reaction terminates, and obtains product;
(4)Weigh 6~8g butyl titanates and 8~12g Boratexes are added in 100~200mL absolute ethyl alcohols, stirring and dissolving
Afterwards, mixed liquor is obtained, it is 35% that 15~20g products, 40~50g wood wax oils and 50~60mL mass fractions are added into mixed liquor
Adlerika, 1~2h of stirring reaction, you can obtain wooden cultural relic dehydration shaping consolidation process agent.
Step(2)When described filtrate and Brazil wax steam stir-fry, 20~30g rosin resins can also be added.
Step(2)The temperature that described steaming is fried is 120~130 DEG C, and the steaming stir-fry time is 15~20min.
Step(2)The temperature of described absolute ethyl alcohol is 0~5 DEG C.
Step(2)The temperature of described distillation is 80~85 DEG C, and vapo(u)rizing temperature is 30~40min.
Step(3)The drop rate of described phosphoric acid solution is 1~3mL/min.
The present invention is compared with other method, and advantageous effects are:
(1)The present invention obtains wood wax oil, wood wax oil by the way that Oleum Verniciae fordii, Brazil wax and rosin resin are carried out into steaming stir-fry, purification
In Oleum Verniciae fordii can penetrate into inside wooden cultural relic, historical relic is carried out to moisten maintenance, and can antisepsis and sterilization, the palm wax in wood wax oil
It can be combined with rosin resin with the fibre compact of wooden cultural relic, increase the intensity of historical relic, while waterproof can be played a part of;
(2)The present invention is hydrolyzed by raw material of HMDO, and its hydrolysate is silica dioxide gel, silica
Gel and then can make the form of silica dioxide gel and chemical bond and timber combine closely with the hydroxyl reaction in timber, so that
Strengthen the intensity of wooden cultural relic, and the free hydroxyl group in wooden cultural relic is reduced, water imbibition is reduced, then be equipped with titanium dioxide,
Titanium dioxide can increase the ageing-resistant performance of wooden cultural relic as ultraviolet light screener.
