Description

A kind of gel compound membrane administered for ancient wall fungus damage

Technical field

The utility model relates to a kind of gel compound membranes administered for ancient wall fungus damage.

Background technique

Ancient wall is that traditional drawing art spreads historical relic remnants so far, is the important cultural heritage of the mankind, has pole High historical cultural environment, artistic value and learning value.However, due to the characteristic of ancient wall itself making material, in addition There is different degrees of disease in of the remote past and many factors influences, the ancient wall saved so far, microbial attack is made At fungus damage be wherein more serious and be difficult to the one kind administered.Similarly, wooden cultural relic, paper relics and cortex historical relic etc. Organic matter type historical relic is by then even more serious the problem of fungus damage.For a long time, germ is killed, prevention and treatment fungus damage is historical relic's protection The problem that reparation personnel face.For microorganism disease on ancient wall ontology control method mainly have at present it is physical Mechanical removal method and chemical agent agent for killing method two major classes type.It is clear using physical mechanical method such as scalpel, hairbrush, vacuum pump etc. Degerming plaque silk is easy to cause secondary damage to ancient wall, and fungus damage microbial spore body can be caused to spread, operator Special Training need to be passed through and workload is huge；And there is also many deficiencies for traditional method for inhibiting or sterilizing using chemical agent Place: (1) a large amount of organic solvent or moisture need to be introduced, for dissolving agent for killing；(2) single when being administered using watering can or hairbrush Plane product formulation rate is difficult to control, and is often resulted in uneven application, is caused the mottled formation color difference of wall painting surface, its aesthstic valence is reduced Value.(3) uncontrollability when watering can is spraying, can pollute mural painting environmental effect, and to mural painting repair operator by Neurotoxic injury；Most traditional chemical fungicide, bacteriostatic agent itself have toxicity, pollute the environment, action potency is short-term Inefficient, there is also the risks utilized by disease bacterium.

Summary of the invention

In view of the above problems, the purpose of the utility model is to provide it is a kind of for ancient wall fungus damage administer Gel compound membrane.

The purpose of this utility model is achieved through the following technical solutions:

A kind of gel compound membrane administered for ancient wall fungus damage, is by contact layer, gel layer, three layer function of waterproof layer Film layer is folded to be constituted, wherein contact layer is long fibre mulberry paper, directly with ancient wall body contacts；Gel layer main body is by chitosan Gel layer is constituted, and is attached to above contact layer；It is 1%-3%'s that liquid phase germicide constituent in chitosan gel rubber layer, which contains mass ratio, Nano-Ag particles, partial size 10-100nm, mass ratio be 0.5%-3% titanium dioxide nanoparticle, partial size be 25-100nm and Mass ratio is 1%-5%, partial size is based on the antibacterial agent for killing of 10-50nm nano granular of zinc oxide, and adds antiphen and benzene pricks chlorine Amine, concentration 0.1%-0.5%；Waterproof layer is made of polyethylene film, and polyethylene film is covered with acrylic based emulsion on one side, is placed in gel Layer is above.

The utility model has the advantages that:

(1) for microorganism disease on mural painting ontology, the utility model is according to different microorganism fungus damage types, in gel The sterilization different with benzalkonium chloride of nano silver, nano-titanium dioxide, nano zine oxide, addition antiphen is selectively configured in layer Medicament.Bactericidal agent permeability is strong, can kill the microorganisms such as most of bacteriums, fungi, mould, spore, bactericidal property is good, nothing Poison is effectively protected mural painting.

(2) gel layer has slow release to sterilization, realizes that medicament is slowly permeated to mural painting, extends the bactericidal effect time, add Strong sterilization effect.

(3) gel mould release bactericidal agent speed is relative constant, for mural painting fungus damage degree, adjusts gel mould in mural painting table The application time at face fungus damage position can play the role of controlling formulation rate.

(4) fungicide is uniformly dispersed in gel layer, when diffusing into mural painting disease position by gel mould, the zone of action The relatively uniform unification of concentration of sterilant.

(5) gel compound membrane can be cut out, by mural painting protect in commonly use the fixation of support top technique and be closely pasted on mural painting table Face realizes contact surface without dead angle.

(6) agent for killing selects green, environment-friendly novel material, and no pollution to the environment meets environmental requirement, it is ensured that repairs operation Personnel safety.

(7) it is widely used.It can be with expanded application in other types historical relics such as wooden cultural relic, cortex historical relic and stone cultural artifacts Fungus damage prevention and treatment.

Detailed description of the invention

FIG. 1 is a schematic structural view of the utility model.

Specific embodiment

In the following, being described further again in conjunction with attached drawing to technical solutions of the utility model:

A kind of gel compound membrane administered for ancient wall fungus damage as shown in Figure 1: is by contact layer 1, gel layer 2, prevents 3 three layer function film layer of water layer is folded to be constituted.First layer is contact layer 1.Contact layer 1 is the long fibre mulberry paper of 1mm thickness, can directly be sticked 4 surface of mural painting ontology in ancient times.It is not damaged to 1 pair of wall painting surface coat of colo(u)r of contact, while there is good water imbibition and permeable Property, the liquid phase fungicide being can absorb through contact layer 1 in gel layer；The second layer is the gel layer 2 of 7mm thickness.Gel layer 2 is attached to Above contact layer 1.2 main body of gel layer is made of chitosan gel rubber.Liquid phase germicide constituent in chitosan gel rubber layer contains Based on the antibacterial agent for killing of nano silver, nano-titanium dioxide, nano zine oxide, mass ratio is added during making chitosan gel rubber For 2% nano-Ag particles, partial size 50nm, the titanium dioxide nanoparticle that mass ratio is 1.5%, partial size is 55nm and mass ratio It is to suppress based on the antibacterial agent for killing of 50nm nano granular of zinc oxide for 3%, partial size, can be also added as needed in fungicide The fungicide such as antiphen and benzalkonium chloride, concentration can be controlled in 0.3%；Third layer is the waterproof layer 3 of 2mm thickness.Waterproof layer 3 is by gathering Vinyl film is constituted, and polyethylene film is covered with acrylic based emulsion on one side.Waterproof layer 3 is attached to above gel layer 2, can prevent gel The outside Environmental diffusion of liquid phase in layer 2 guarantees the liquid phase fungicide in gel layer 2 to mural painting direction uni-directional diffusion.

In wall painting surface in use, can cut the gel mould made according to wall painting surface disease region, make Gel mould is consistent with disease region.Then the alignment of gel layer contact surface 1 mural painting fungus damage region is sticked, the fungicide in gel mould It is slowly penetrated by diffusion to contact layer 1 and wall painting surface, kills the germ in mural painting.Gel mould application time is before Phase experiment and disease severity general control are within 10-30 minutes.After, gel mould is removed, operation is completed.
