Detailed Description of the Invention

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a resin composition for preserving a buried object and a method for preserving the same. More specifically, it relates to an ancient dwelling site containing an organic polysiloxane-polyoxyalkylene copolymer as an essential component. The present invention relates to a resin composition for preserving buried objects in the soil such as a sunken ship, in mud and / or underwater, and a method for preserving the buried object using the composition.

[0002]

2. Description of the Related Art When a soil containing water, mud and / or a buried object in water is exposed to air, it will be contracted and destroyed by evaporation of water, and it is difficult to maintain its form. . Therefore, store these at room temperature on the ground,
When exhibiting, etc., it is necessary to perform precise management such as preventing water from draining or constantly supplying water, and in order to maintain the storage condition, use a solid hydrophilic resin at room temperature. It has been common practice to replace the water with some high molecular weight polyethylene glycol. However, in the method using polyethylene glycol, since permeability and internal diffusion transfer are slow, it takes a very long time. Usually, polyethylene glycol is replaced with an aqueous solution by gradually increasing its concentration. The concentration can only be increased to about%, and even in that case it is about 3
There has been a problem that after spending more than a year, only about 50% of the water content can be replaced with polyethylene glycol, and eventually the above-mentioned management is required. Furthermore, in the method using polyethylene glycol, the target buried object must be once taken out and transported, and the temperature is controlled so that all or part of the target buried object is immersed in the polyethylene glycol aqueous solution. The size of the target buried object was also limited because it required special equipment such as a swimming pool.

Organopolysiloxanes and organosilicon compounds are compounded in organic resins due to their unique interface characteristics,
It is widely applied to the application of water repellency, low friction property, mold release property to building materials such as mortar and concrete, stone materials, fibers and resins by forming a coating film by curing. In addition, Japanese Examined Japanese Patent Publication 62-24
Japanese Patent Laid-Open No. 017 discloses a coating composition in which a silicone-based graft copolymer is dissolved in an organic solvent for a coating-forming resin to give a coating having water repellency and low friction on the coating surface. . However, this coating composition does not have sufficient penetrability and adhesiveness to the substrate, and there is a problem that the strength and the durability are insufficient. Further, due to the water repellency, there are problems that static electricity is easily generated, stains are easily caused, and washability with water is poor. Moreover, no consideration was given to mold resistance and easy washability. Furthermore, when a film is formed and stored on the state where a part of the target buried object remains buried, in soil,
There has been a problem that moisture penetrating from mud and / or water is accumulated in the above-mentioned buried object by this film.

BEST MODE FOR CARRYING OUT THE INVENTION A specific organic polysiloxane-polyoxyalkylene copolymer of the present invention or a storage resin composition containing this and polyoxyalkylene as essential components is excellent in water substitution property and shape retention property, It was possible to replace the water content of soil, mud and / or underwater buried matter in a short period of time without damaging the buried matter. In addition, the replacement rate of water is about 10 without using special equipment or partially buried.
It was possible to set it to 0%. As a result, for example, a buried object that is partially submerged in soil, mud and / or water such as a wetland and contains water, or submerged in mud or water such as the seabed and contains water. In the case of storing the buried product in the state of being, it is also possible to carry out a water replacement operation by first exposing this buried product to the air and then immersing it in a stock solution or an aqueous solution of the resin composition for water replacement of the present invention,
Alternatively, excavate only the upper part and surround it with concrete, iron plate, etc. to pour this liquid, repeatedly apply it, or wrap it with a fibrous or sponge-like retainer impregnated to perform the water replacement work. It becomes possible. Therefore, the number of buried objects is increased, and even large ones can be excellently preserved. For example, if you want to save the remains of ancient forests, dwellings, etc., you can save each buried thing at the place where it was found, as it was before it was buried like roots and pillars in the soil. However, it can also be suitably used for huge buried objects such as buried or sunken ships.

In the present invention, a thermosetting resin and / or a thermoplastic resin composition which is a resin composition for coating after water substitution, particularly a specific non-reactive organic polysiloxane-polyoxyalkylene copolymer is used as an essential component. The composition containing an isocyanate resin or a resin obtained from ethyl silicate and / or a condensate of ethyl silicate has excellent permeability and diffusibility into a base material, and the details of a buried matter in soil, mud and / or underwater It penetrates deep into the interior and, after curing, has excellent waterproofness, breathability, strength, and durability, as well as elasticity, adhesiveness, and void filling. In addition, it is easy to wash and can prevent the formation of mold and moss. Therefore, in addition to the waterproofing effect, the salt damage preventing effect, and the frost damage preventing effect, it is possible to impart an aesthetic maintaining effect to soil, mud and / or underwater buried objects. In addition, if you store a part of the target buried object in a buried state, because it has excellent breathability,
Water that penetrates from soil, mud and / or water is less likely to accumulate in the target buried object. Further, since the antistatic effect is excellent, stains are hard to occur, and since the coating surface is wet without forming water drops into spherical shapes, not only is it possible to wash with water, but also the washing action by wind and rain and the self-cleaning action are excellent. In addition, the recoating property and the replenishment of a specific non-reactive organic polysiloxane-polyoxyalkylene copolymer can extend the cleaning action and the self-cleaning action. In addition, it has excellent heat resistance, cold resistance, weather resistance, and chemical resistance. Furthermore, when the coating resin composition contains a reducing agent, the oxidizing substances and dirt in the buried product are removed, and it is possible to impart excellent preservability while restoring the color tone at the time of burial.

At this time, when a substrate not coated with the film-forming resin composition sample was placed side by side on the test piece as a blank, it was confirmed that mold grows on the entire surface after 3 months. ◎: No mold is generated on the coated surface ○: Mold is formed on less than 50% of the coated surface area △: Mold is formed on 50% or more of the coated surface area ×: Mold is formed on the entire coated surface

4) Easy-Washability Test A line was drawn on the cured coating film obtained by the mildew resistance test with an oil-based black pen, left at room temperature for 24 hours, and then wiped off with a wet rag to determine how dirty the coating film was. Was evaluated according to the following criteria. ◯: No stain at all Δ: 50% or more stain can be removed, but black marks remain ×: Stain remains considerably

5) Breathability test For the base material after water substitution obtained in the shape retention test,
A sample of the resin composition for forming a coating film was applied at 0.2 g / cm ² and left at room temperature for 3 days for curing to prepare a test piece. Place this test piece on a 100 cc glass beaker containing 80 cc of water so that the test piece is covered for 2 weeks.
The sample was allowed to stand under the conditions of 5 ° C. and a humidity of 60%, and the change in the volume of water was measured.
