Description
Technical field
The invention belongs to historical relic's protection fields, and in particular to a kind of waterlogged wooden culture relics composite consolidation material and its preparation side
Method and application.
Background technology
The mankind are with a long history using timber, and the development course for the wooden cultural relic that is unearthed is reflected from different aspect built at that time
The state of development of industry, handicraft and the tool of production and industrial art, carrier of the ancient times timber as human civilization are research ancient times
The valuable geological material of culture, art, science and technology has very high historical value.Wooden cultural relic buries the ring in rich groundwater
When in border, the effect of the chemical compositions such as acid, alkali, salt and the erosion of domestomycetes make cellulose and hemicellulose decompose, cell wall
It is destroyed, gradually rotten to lose support, soft frangible, to waterlogged wooden culture relics progress, timely dehydration shaping is particularly significant.
Current main waterlogged wooden culture relics reinforcing mode is chemosmosis displacement method, i.e., is displaced with the solute in reinforcement material solution
Moisture in wooden cultural relic plays the effect that filling is reinforced.Meanwhile still there is a strong possibility the property of the wooden cultural relic after reinforcing is by fungi
Based on microorganism infringement, although can reach fungistatic effect using preservative, preservative itself has injury to wooden cultural relic.
The dosage of preservative can be reduced using the reinforcement material with certain antibiotic property, reduce the secondary injury to historical relic.Therefore, it reinforces
The raising of material antibiotic property is one of urgent problem to be solved during waterlogged wooden culture relics are protected.
Invention content
The present invention provides a kind of waterlogged wooden culture relics composite consolidation materials and preparation method thereof, and composite consolidation material is being protected
While card is to wooden cultural relic consolidation effect, outstanding antibiotic property is provided.
A kind of compound of waterlogged wooden culture relics composite consolidation material and chitosan oligosaccharide, reinforcement material is preferably xylitol, sea
Algae sugar, lactitol, ethylene glycol, PEG (molecular weight 800-3000), chitosan oligosaccharide molecular weight are 300-3200.Preferably, reinforcement material
Concentration, xylitol be 40-60% (w/w), trehalose be 40-60% (w/w), lactitol be 40-60% (w/w), ethylene glycol
For 20-40% (w/w), PEG 40-70%.Chitosan oligosaccharide is 0.1-10%.
The mixed solution achievees the effect that reinforce in such a way that water timber is satisfied in immersion shapes, and wherein reinforcement material increases full
The fastening strength of water wooden cultural relic, chitosan oligosaccharide provide antibiotic property.
Secondly, the present invention also provides a kind of preparation methods of waterlogged wooden culture relics composite consolidation material, including：
(1) compound concentration is the xylitol solution of 10-80%；
(2) 0.1-10% chitosan oligosaccharides are added in the xylitol solution of a concentration of 10-80%.
Consolidation time is 1-8 weeks.
In addition, the answering in full water wood reinforcing the present invention also provides a kind of waterlogged wooden culture relics composite consolidation material
With.The waterlogged wooden culture relics composite consolidation material of the present invention is for reinforcing by the Medical tongue blade of chemical degradation, the pressure after reinforcing
Hyoplastron, which has, preferably resists swollen rate and antibiotic property.
Description of the drawings
Fig. 1 be using undegraded spatula, unguyed chemical degradation spatula and composite consolidation it is material reinforced after change
Learn form comparison of the degradation spatula after over dry, it can be seen that the chemical degradation spatula form after reinforcing is more stable, curling
It is substantially reduced compared with unguyed sample with the degree of tilting.
Fig. 2 is the anti-swollen rate of each group chemical degradation spatula after embodiment 1 is reinforced, it can be seen that each group sample resists swollen rate
It is in higher level, and adds chitosan oligosaccharide in composite consolidation material and resists swollen rate to have no significant effect in sample.
Fig. 3 is the mass loss rate of each group chemical degradation spatula after 2 mycocriny of embodiment, it can be seen that few with shell is not added with
The control sample of sugar is compared, and the mass loss rate for adding the material reinforced rear sample of composite consolidation of 0.5% and 1% chitosan oligosaccharide is aobvious
It writes and reduces.
Specific implementation mode
The material reinforced chemical degradation spatula of 1 waterlogged wooden culture relics composite consolidation of experimental example
1. the preparation of chemical degradation spatula
(1) Medical tongue blade is immersed in the sodium hydroxide solution of a concentration of 10% (w/v), chemical degradation 1 week；
(2) spatula after chemical degradation is immersed in distilled water, periodically changes water daily until aqueous solution is in neutrality.
2. the preparation of waterlogged wooden culture relics composite consolidation material
(1) six groups a concentration of 50% of xylitol solution is prepared；
(2) six groups a concentration of 50% xylitol solution respectively in addition concentration 0%, 0.05%, 0.1%, 0.25%,
0.5%, 1% chitosan oligosaccharide, as waterlogged wooden culture relics composite consolidation material.
3. the material reinforced chemical degradation spatula of waterlogged wooden culture relics composite consolidation
(1) chemical degradation spatula is separately immersed in six groups of waterlogged wooden culture relics composite consolidation materials, is reinforced 6 weeks；
(2) spatula is taken out, the volume of the front and back spatula of drying is measured, calculates and resist swollen rate.As a result such as Fig. 2, each group are compound
Chemical degradation spatula after reinforcement material is reinforced has higher anti-swollen rate, illustrates that consolidation effect is preferable.
2 resistance to mycocriny of experimental example is tested
1. culture experiment strain
(1) river sand sawdust culture medium is prepared：Dry river sand (20-30 mesh) 150g, the horse hair cleaned in the triangular flask of 500ml
Slack list material sawdust (20-30 mesh) 7.5g, corn flour 8.5g, brown sugar 1g.Stir it is smooth after put on surface and raise wood (3cm*1.5cm*
1.5mm) 3 pieces, 100ml malt liquid glucoses are added, bottleneck and packet waterproof paper are clogged with rubber stopper, it is for use after sterilizing；
(2) experimental strain gloeophyllum trabeum (Gloeophyllum terbium) is inoculated into river sand sawdust culture medium, is trained
It supports 1 week；
2. mycocriny sample
(1) sample, is put into the river of inoculation gloeophyllum trabeum by the absolute dry mass for weighing chemical degradation spatula sample after reinforcing
On feeding wood in sand sawdust culture medium, mycocriny 12 weeks；
(2) spatula sample is taken out, the absolute dry mass of sample after mycocriny is weighed, calculates mass loss rate.As a result such as Fig. 3,
Compared with the control sample for being not added with chitosan oligosaccharide, the material reinforced rear sample matter of composite consolidation of 0.5% and 1% chitosan oligosaccharide is added
Amount loss rate is substantially reduced, and illustrates that the chitosan oligosaccharide of 0.5% or more addition can be such that the antibiotic property of composite consolidation material significantly improves.
