DETAILED DESCRIPTION OF THE INVENTION Field of Industrial Application The invention relates to a two-component fast-curing material for repair and recovery (restoration or restoration) work, mainly used in the civil engineering or architectural fields. Conventional technology In the civil engineering and construction fields, areas that have been repaired or restored are often finished by filling them with hardening inorganic materials (mortar, concrete, asphalt). Instead of these inorganic materials, epoxy resin mixed with sand is often used. For example, when constructing or renovating a manhole on a road or on a property, the relevant area must be dug up and the work carried out, and then a filler is packed between the inserted iron manhole opening and the surrounding concrete or asphalt area. It is necessary to fix the manhole opening by using curable inorganic materials or epoxy resins as mentioned above to fill and fix the manhole opening. In addition to fixing manhole openings, we also work to restore missing parts, cracks, depressions, repaired parts, etc. in concrete structures, construction surfaces, asphalt construction surfaces, etc.
Curable inorganic materials or epoxy resins such as those mentioned above are commonly used. Problems to be solved by the inventionHowever, it is difficult to repair using mortar or concrete●
When performing restoration work, it takes a considerable amount of time for the hardening to reach the specified strength, so if the area to be worked on is a road, sidewalk, platform, or other area where cars and people pass, However, there is the inconvenience of having to restrict traffic for a long time even after the construction is completed, and even having to take measures to prohibit traffic during that time or take final measures to clear traffic. When performing repair/recovery work using epoxy resin, it takes about a day and a night to complete curing, which causes the same problem as above. When performing repair/recovery work using asphalt, it can be cured in a short time, but it requires pressure to hold it down, which is disadvantageous in terms of equipment and labor. Considering today's traffic and labor conditions, construction can be carried out in short order, and the construction can be completed quickly (preferably within 2 days).
It is strongly requested that the road become passable (within 30 minutes). When repairing damaged or cracked parts of steel tower foundations in the mountains, we ensure that the mortar, concrete, or epoxy resin filled in the repaired parts has completely hardened and has achieved the desired strength. The construction work will not be completed until this is done. Therefore, there is a disadvantage that it is necessary to have a worker wait for a long time for confirmation, or to have a worker dispatched another day to confirm. 2 on top
In these specific cases, if complete hardening can be achieved in a very short period of time after repair or restoration work, the above problems will be solved all at once. In addition, when filling and curing with curable inorganic materials among the above, the contact areas between the filling material and existing concrete parts, asphalt parts, and the contact areas between the filling material and steel members will be bonded simply by being in contact. In many cases, this is hardly done, and questions remain about the strength of the interface. In this case, if not only filling and curing but also sufficient adhesion of the interface is achieved, the repair/recovery will be more complete. In view of this situation, the Tai invention was designed to completely cure in a very short time (for example, within 3 to 30 minutes) after repair or recovery work, and to provide sufficient adhesive strength at the interface between the filled part and the surrounding area in the construction area. The purpose of this project is to provide a fast-curing material for repair and restoration work that simultaneously solves the two problems of achieving Means for Solving the Problems The curable material for repair and restoration work of the present invention uses di-cyanoacrylate as the first agent and coarse granular aggregate as the second agent. The present invention will be explained in detail below. Examples of the 2-cyanoacrylate include various 2-cyanoacrylates in which R in the formula CN CH2 =C-COOR is an alkyl group, an alkenyl group, an alkynyl group, a cycloalkyl group, an aryl group, an alkoxyalkyl group, a tetrahydrofurfuryl group, etc. is used. A typical example is an alkyl 2-cyanoacrylate in which R has 1 to 4 carbon atoms. Highly purified 2-cyanoacrylate has the property of curing in seconds, but for the purpose of wood invention, such speed is not required, and workability must also be ensured, so it is necessary to cure in about minutes. It is sufficient as long as it has a certain speed (for example, curing is completed in several minutes to several 10 minutes, especially about 3 to 30 minutes). Therefore, the 2-cyanoacrylate used in the present invention does not necessarily require a high degree of purification, which is also advantageous in terms of cost. Coarse granular aggregates include those conventionally used as aggregates for mortar and concrete, such as sand, gravel,
Crushed stone (of rocks and slag), ply ash, volcanic rubble,
Volcanic sand, hillstone, pearlite}. 11 clay, expanded shale,
Coal debris, expanded slag, bozolan, etc. are used. Crushed glass, crushed concrete, metal particles, crushed ceramics, and other inorganic industrial wastes can also be used. In addition, organic aggregates such as particulate rubber (pulverized waste tires, etc.), particulate plastics, and thick pieces can also be used. If water adheres to coarse granular aggregate, hardening may progress when mixed with 2-cyanoacrylate.
Coarse granular aggregates are required to be dry enough to avoid such problems. Considering the particle size, availability of a certain quality, cost, compatibility with 2-cyanoacrylate, strength after hardening, etc., at least a portion (for example, 20% by weight or more) of the coarse granular aggregate should be silica sand. It is preferable that The fast-curing material for repair and restoration work of Wood Invention is based on the above-mentioned 2-
Cyanoacrylate is used as the first agent, and coarse granular aggregate is used as the second agent. If necessary, various additives such as a coloring agent, a viscosity modifier, a curing rate modifier, and fibers can be added to at least one of the first part and the second part. These additives are prepared separately from the first and second parts, and are prepared separately from the first and second parts.
It can also be added when mixing with the agent. 2- The blending ratio of coarse granular aggregate to cyanoacrylate cannot be clearly defined because it varies greatly depending on the type of both, specific gravity of the latter, shape, degree of bolus, etc.
1 to 1 part of coarse aggregate to 1 part by weight of cyanoacrylate
It is often used in an amount of about 0.00 parts by weight, especially about 2 to 80 parts by weight. When the specific gravity of coarse granular aggregate is high, even if a large amount is added in terms of weight, the volume will not be that large. Even within the above range, there is a blending ratio that exhibits the best strength depending on the combination of the 2-cyanoacrylate and coarse granular aggregate used, so it is preferable to find the optimal ratio through preliminary studies. Mix the first and second agents immediately before use. Since the two can be easily mixed, there is no need to perform full-scale stirring using a rotary stirrer or the like during actual mixing, just by shaking or stirring.
It is sufficient to apply vibrations or simple rotating shifts. The first agent is placed in a suitable capsule or small container made of glass, ceramic, plastic, etc. in advance, and
It is also preferable to place this capsule or small container in a container containing an appropriate amount of the second agent, and to break the capsule or small container immediately before use to mix the two. The curable material for repair and restoration work of the present invention can be used as a material to fill the gap between an installed object and the surrounding concrete or asphalt part, or as a material for filling a gap between an installed object and the surrounding concrete or asphalt part, especially in repair and restoration work in the civil engineering and architectural fields. It is suitable as a material for restoring defects, cracks, depressions, repaired areas, etc. on sprayed concrete slopes, asphalt construction surfaces, etc. Effect 2 - When the first part consisting of cyanoacrylate and the second part consisting of coarse granular aggregate are mixed and filled into the area to be repaired,
2-Cyanoacrylate cures in minutes. When the filling amount is relatively large, heat generation is also observed, but this heat generation actually contributes to improving the curing speed, and when the target material has heat softening properties such as asphalt, the asphalt around the filling material softens and melts. However, it has the advantage of increasing adhesive strength at the interface. It is well known that 2-cyanoacrylate itself cures quickly, but when curing only with 2-cyanoacrylate, the cured product is brittle and has insufficient weather resistance to be applied to the civil engineering and architectural fields. In addition, during curing, a considerable amount of (
(for example, about 10%). However, 2-
In a system that uses a mixture of cyanoacrylate and coarse granular aggregate, the strength of the cured product increases, it also affects weather resistance, and the shrinkage rate is so small that it does not cause any practical problems. , exerts unexpected effects. If the object to which it is applied is highly acidic, the curing speed may be slow; however, in this case, rapid curing can be ensured by taking measures such as pre-priming the object. EXAMPLES Next, the present invention will be further explained with reference to examples. Below, "parts" refer to parts by weight. Example 1 A part of a concrete road was hollowed out in a circular shape, the old manhole opening was removed, and a separate iron manhole opening was fitted into the hollowed out area. After pouring 1 part of ethyl 2-cyanoacrylate into a container containing 6 parts of a mixture of dry No. 5 to 7 silica sand, the container was rocked to mix the two. Since ethyl 2-cyanoacrylate easily penetrated into the gaps between the silica sand particles, this mixing operation could be carried out smoothly and in a short time. After the mixing operation was completed, the mixture was filled into the gap between the manhole opening and the concrete road cutout, and soon a hardening reaction began and heat generation was observed. It took only about 15 minutes to completely cure, and there was no problem even if a car drove through the area immediately after it was completely cured. About 20 minutes after filling, the adhesive strength between the filled material and the manhole mouth, and between the filled material and the concrete part was examined, and the adhesive strength was extremely strong. Furthermore, even after curing was completed, there were no gaps caused by shrinkage in the filling material between the manhole opening and the concrete section. Comparative Example 1 When mortar was used as the filling material for the construction work in Example 1, it took at least one day and night before the road became passable, and during that time, traffic was obstructed. It should be noted that the filled mortar had only hardened itself, and the adhesive strength between it and the manhole opening and the surrounding concrete was small. Comparative Example 2 When epoxy resin mixed with silica sand was used as the filler for the construction work in Example 1, it took at least one day and night before the road became passable, and traffic during that time was obstructed. however,
The adhesive strength between the manhole opening and the surrounding concrete part was the same as in Example 1. Example 2 A manhole opening in an asphalt site was replaced in the same manner as in Example 1, but it completely cured within a few minutes after the filling operation, and there was no problem even if a car passed through it immediately after it was completely cured. did not occur. Example 3 0.5 part of ethyl 2-cya/7 acrylate and 0.0 parts of Improvil 2-cyanoacrylate were placed in a container containing 5 parts of a mixture of dried No. 5 to 7 silica sand and 1 part of crushed waste tire.
.. After pouring the mixture with 5 parts, the container was shaken to mix the two. This mixing operation could be performed smoothly and in a short time. After the mixing operation was completed, the mixture was filled into the depressions created by repairing the concrete platform, and then scratched with a board to make the surface flush with other parts. The curing reaction will begin soon, and approximately 1
Curing was completed in 5 minutes. The adhesion between the filling material and the surrounding concrete area was sufficient, and no dents due to volumetric shrinkage were observed in the filling area, and no abnormalities were observed even after 3 months, despite being exposed to rainwater and direct sunlight. I was not able to admit. Effects of the Invention By using the fast-curing material of the present invention, complete curing can be achieved in a very short time after repair or restoration work, so final inspections can be made on the spot, and roads can be reopened to traffic immediately. Sufficient adhesion is also ensured at the interface between the filled part and the surrounding area at the construction site. In addition, the filler has high strength after curing, is weather resistant, and has a low shrinkage rate. 2
- Although cyanoacrylate is generally expensive, the purpose of the present invention does not require much purity, and since it is used in conjunction with a large amount of coarse granular aggregate, the amount used is not large.
Furthermore, since it has the excellent effects mentioned above, it has great benefits that outweigh the high cost of raw materials.
