The present invention relates to a structure having insulation, and more particularly, a structure that can be used as a roadbed facility requiring insulation including an electric device inside a prop, a telephone pole, a traffic light, a street lamp, a traffic sign, a control box, and the like. As a result, the surface energy is low, the construction is easy, and the physical properties such as weather resistance, scratch resistance, chemical resistance, impact resistance, and abrasion resistance of the surface can be improved, and the uneven structure formed by the glass beads causes the surface to be exposed in the air. The present invention relates to a structure having insulation that prevents the adsorption of dust and moisture and prevents the reduction of the insulation effect, and prevents advertisements such as stickers and posters from adhering to the adhesive and paste to damage the appearance of the structure. .

The use conditions of electric facilities on the road are harsher than indoors, and the damage of insulation coating is easily caused by temperature change and physical shock.

When the insulating film is damaged, it acts as a passage of electrical leakage, so the electrical insulating layer must have abrasion resistance along with strength not to be damaged by adhesion and impact and water absorption, and thus have insulating properties.

The roadbed is equipped with a large number of roadbed facilities such as props, telephone poles, street lights, traffic lights, traffic signs, and control boxes.These facilities have various shapes such as metal pipes, metal props, concrete props, metal polyhedrons, and concrete polyhedrons. The strut and the like are generally provided with a device such as a ballast and the like, and a power is supplied through the strut. Therefore, when a short circuit occurs in the power supplied to the support, there is a problem that such a short circuit is connected to a safety accident, especially on rainy or high humidity days.

In order to solve this problem, the ground fault or leakage current flows to ground through ground installed in the ground, and a circuit breaker for blocking the ground fault is installed. However, the installation of the props, etc., without installing the ground in the ground is not inconsistent, and the existing wires or breakers installed in the support, such as those that have been used for a long time to cause the short-circuit caused by the short-circuit or proper leakage function Not doing so, replacing these aging wires and breakers has the disadvantage of requiring a lot of cost and effort.

In order to solve the above problems, Utility Model Registration No. 200474 discloses a strut formed with an insulating coating layer made of an insulating material or a non-combustible insulating material on the inner surface of an iron plate or a rolled steel sheet, but the insulating coating layer is easily damaged. Since leakage current flows to the damaged part, there is always a risk of electric shock for pedestrians walking through the sidewalk, and the effect of insulation by only applying an insulating material inside the prop is very small.

In addition, Patent Application No. 10-2002-0013363 installs an attachment panel coated with an insulating material layer is installed in the support, the insulating material layer includes an adhesive layer, an asbestos layer, and an insulating coating layer coated with an adhesive Although it is disclosed, it is difficult to construct, and still difficult to expect the effect of insulation for the parts other than the attachment panel, in particular, there is a problem that still contains the risk that the current leaked from the inside of the prop as it is delivered to the outside.

Accordingly, various methods have been attempted to manufacture an insulated post, but an effective prevention means with economical efficiency has not been proposed.

In order to solve the problems of the prior art as described above, the present invention can be used as a structure that is a roadbed structure that requires insulation, including props, telephone poles, traffic lights, street lights, traffic guide signs, control boxes, and the like, low surface energy, It is easy to install, and it can improve the physical properties such as weather resistance, scratch resistance, chemical resistance, impact resistance, and abrasion resistance of the surface, and adsorption of air dust, moisture, and moisture on the surface due to the uneven structure formed by glass beads. The purpose of the present invention is to provide an insulating structure that prevents reduction of the insulation effect and prevents advertisements such as various stickers and posters from being adhered to the adhesive, glue, or the like, thereby damaging the appearance of the structure.

In order to achieve the above object, the present invention

Hollow structure;

A first insulating resin layer made of a first insulating resin applied to an outer surface of the structure; And

An object of the present invention is to provide an insulating structure comprising a glass bead layer comprising a plurality of glass beads which are bonded to the top surface of the coated first insulating resin and protrude outwardly.

Hereinafter, the present invention will be described in detail with reference to the drawings.

The insulating structure of the present invention is a hollow structure 40, a first insulating resin layer 20 made of a first insulating resin applied to the outer surface of the structure 40, the upper surface of the first insulating resin applied It is characterized in that it comprises a glass bead layer 10 consisting of a plurality of glass beads to be bonded and protruded to the outside.

 The structure may include a structure used as an outer structure having various shapes including an electric device such as a pillar, a telephone pole, a street lamp, a traffic light, a traffic guide sign, a control box, and the like, including an insulation function. Among them, props, telegraph poles, street lights, traffic lights, etc. can be classified into posts in the form of hollow pillars, and traffic signs and control boxes can be classified into control boxes as hollow polyhedrons. That is, the structure of the present invention has a structure including an electrical installation therein as a hollow having a predetermined space therein. The hollow part is not limited to any specific shape, and may have an outer shape such as props, telephone poles, traffic lights, street lamps, traffic signage, control boxes, and the like. It is included because it is possible to cause a short circuit accident.

In addition, it may be configured to further include a second insulating resin layer 30 made of a second insulating resin applied to the inner surface of the structure 40. In this case, the insulation effect can be further increased, and the case of applying it to the prop as an example of the relief is as shown in FIG. 1.

In addition to the above, the upper surface of the coated second insulating resin layer further comprises a glass bead layer comprising a plurality of glass beads coupled to the upper surface of the coated second insulating resin layer and protruding outwardly into the structure. It can also be configured.

The first insulating resin or the second insulating resin used in the present invention serves as an insulating material of the insulating structure, and can be mainly used for resins, which are usually used for exteriors, in particular acrylic resins, ceramic resins, or urethane resins. It is preferable to use acrylic resin or fluorine resin, and more preferably, the first insulating resin uses acrylic or fluorine resin having high weather resistance, and the second insulating resin uses epoxy resin having good economical efficiency. It is good.                     

The acrylic resin may be a solvent-type acrylic urethane, an aqueous acrylic hydrosol, an emulsion-free solvent-based acrylic silane, or an ultraviolet curable acryl based on methacrylic acid or an acrylic acid derivative.

The urethane-based resin may be used as a general urethane-based resin used in the art, of course, generally known from organic compounds and organic polyisocyanates containing active hydrogen atoms found in the hydroxyl and amino portions, for example. Thermosetting resin.

The ceramic resin may be a silicate ester, a hydrolysis product thereof, a water dispersion silica sol, an alcohol dispersion silica sol, or the like.

In addition, it is preferable that the viscosity of the insulating resin is in the range of 100,000 to 200,000 cPs, more preferably around 150,000 cPs for ease of application.

The first insulating resin layer is formed by applying the first insulating resin on the outer surface of the structure, the coating method may operate a variety of known methods, specific examples thereof, such as painting with a brush, spray, dipping Can be applied.

The second insulating resin layer is formed by coating the second insulating resin on the inner surface of the structure, the coating method may operate a variety of known methods as described above, specific examples thereof, such as painting, spraying, dipping And the like can be applied.

In addition, the upper surface of the coated first insulating resin is provided with a concave-convex surface of the glass surface to be bonded to the first insulating resin layer, which not only makes the adhesion of moisture or moisture difficult, but also difficult to adhere to other advertisements, adhesives and protrudes to the outside. It has a glass bead layer which consists of many glass beads.

In the method of forming the glass bead layer, the first insulating resin as described above is applied to an adhered surface, which is an outer surface of a structure which is a roadbed facility, and the glass beads are sprayed and cured on top of the insulating resin before the insulating resin is cured. It can be attached to, and through this can be formed glass bead projections, it can be applied in a similar manner in the case of forming inside the insulating structure.

The glass bead used in the present invention has a spherical shape, and the glass beads of the spherical shape form a glass bead protrusion on the upper portion of the insulating resin, thereby increasing the insulation function of the structure due to the insulating glass bead, and also being deposited. By reducing the contact surface between the surface and the adhesive to reduce the damage caused by the short circuit, in addition, if the air or water in the unevenness between the glass bead projections formed on the insulating resin, the air or water to the top of the glass bead While spreading, an air film or water film is formed to lower the surface tension of the object, thereby acting to prevent adhesion or adhesion of the adhesive.

After the glass beads are sprayed and cured on the upper part of the insulating resin, the glass beads may be fixed by the insulating resin and protrude from the upper part of the insulating resin to form protrusions. It is obtained by processing the glass powder obtained by grinding | pulverizing a cullet, glass fiber, or a glass curette, and a glass composition will not be specifically limited if it is compatible with insulating resins, such as A, C, E, and alkali-resistant glass powder composition.

The glass beads may be spherical, elliptical, or glass beads of any shape equivalent thereto, and may be used, from those in which various sizes are distributed to those of only a predetermined size.

The particle diameter of the glass beads may be appropriately selected and used according to the material, use, and the like of the structure-adhered surface of the hearth facility in which the insulating structure of the present invention is formed, and preferably 0.01 μm to 3 mm, more preferably It is preferable that it is 0.1-1.5 mm. They can also exhibit a variety of shapes and properties by the combination of beads having a small particle size of several μm and a large particle size of several mm. However, when the particle diameter of the glass beads exceeds 3 mm, there is a problem that the contact surface and the contact surface of the adhesive is increased, the dispersibility may be lowered.

Glass beads as described above can be used by adjusting the appropriate amount according to the anti-sticking, adhered surface required, in particular, it is preferably included in 50 to 150 parts by weight based on 100 parts by weight of the insulating resin solids, more preferably 70 To 90 parts by weight. If the content is less than 50 parts by weight, the amount is so small that the effect of preventing the penetration of moisture or water and the adhesion of the adhesive is insignificant. If it exceeds 150 parts by weight, the content is relatively higher than that of the insulating resin. There is a problem that the glass beads may be dropped after the insulating structure is hardened.

As described above, the glass beads sprayed on the upper portion of the insulating resin before the insulating resin is cured and fixed by the insulating resin applied to the outer surface of the structure as shown in FIG. 1 protrude from the upper portion of the first insulating resin layer 20. The glass bead layer 10 made of the glass bead protrusions is formed.

In addition, when forming the insulating structure of the present invention, glass powder (glass power) may be further mixed with the insulating resin and applied to the adhered surface.

The glass powder has a thermal expansion coefficient similar to that of an insulating resin, and thus does not cause gaps due to thermal contraction and expansion, thereby improving the bonding force between the glass beads and the insulating resin so that the glass beads do not fall off or fall off. As well as moisture and moisture on the surface of the adhered surface, it is possible to more effectively prevent the attachment of advertisements or adhesives such as posters and stickers. In addition, the glass powder inhibits interfacial separation and absorbs and transmits an impact applied from the outside to form an insulating structure coating structure in which damage is significantly reduced.

The glass powder may be used in a variety of particle shapes and particle sizes, the particles of the glass powder is obtained by pulverizing glass, cullet, glass fiber, or glass curette, glass composition is A, C, E, alkali resistance It will not specifically limit, if it is compatible with insulating resins, such as a glass powder composition, Especially, glass powder of an E-glass composition is more preferable at the adhesiveness with respect to various materials.

Although the particle diameter of the said glass powder is not specifically limited, It is preferable that it is 10 micrometers-1 mm especially, More preferably, it is 5 micrometers-1 mm. If the particle diameter of the glass powder is too small, there is a problem in that the bonding force improvement effect between the glass bead and the insulating resin is insignificant. If the glass powder is too large, the glass powder may not be uniformly mixed with the insulating resin, and the strength of the insulating structure may be lowered or the shrinkage and expansion may be reduced. There is a problem that this may increase.

The glass powder is preferably contained in 20 to 150 parts by weight based on 100 parts by weight of the insulating resin solid content. If the content is less than 20 parts by weight, there is a problem in that the effect of imparting a bonding force between the glass beads and the insulating resin is insufficient, and if the content exceeds 150 parts by weight, the content of the insulating resin is relatively reduced, the insulation of the present invention on the adhered surface There is a problem that the adhesion of the structure may be lowered.

In addition, when forming the insulating structure of the present invention, the insulating resin may further include a glass fiber (glass fiber) as necessary. The glass fiber acts to increase the tensile strength and crack resistance of the cured insulating structure.

The glass fiber may be a long glass fiber of the E composition or a fiber of an alkali resistance composition, specifically, a chopped fiber cut into glass or carbon fibers having a fiber diameter of 10 to 20 ㎛ in a uniform strand length (chopped fiber) ) Or milled fibers prepared by milling to an average fiber length can be used. In particular, the chopped fibers are preferably cut to a fiber length of about 2 to 12 mm, and the pulverized fibers preferably have an average fiber length of 100 to 300 m. In particular, the pulverized fiber is preferable when considering the tensile strength reinforcement and dispersibility of the insulating structure of the present invention, it is also possible to use a mixture of the chopped fiber and the pulverized fiber.

The glass fiber is preferably included 1 to 100 parts by weight based on 100 parts by weight of the insulating resin solids. When the content of the glass fiber is within the above range, there is an advantage that cracking, shrinkage, and expansion of the cured insulating structure do not occur.

In addition, the insulating structure of the present invention may further include additives such as conventional fillers, pigments, reaction catalysts, thickeners, flow control agents, wetting agents, UV stabilizers, or anti-settling agents, or mixtures thereof.

Specific examples of the insulating structure of the present invention having the above configuration corresponds to roadbed facilities such as props, telephone poles, traffic lights, street lights, traffic guide signs, and control boxes as described above.

The formation of the insulating structure as described above may be formed on the outer wall of a structure such as a hearth facility already installed, or may be formed directly on the surface thereof while producing a structure such as a new hearth facility.

The mixture of the insulating resin and glass powder, glass fiber, or additives as necessary may be selectively used using a conventional coating method used in the art according to the material, requirement, area, etc. of the surface to be coated. Of course, it can be applied to a nonwoven fabric, and in particular, if the components are likely to be scattered when applied in an outward direction of gravity, it is preferable to prevent them from scattering by using a roller or a brush, and the components may not be scattered. In this case, it is preferable to use a spray coating.

The insulating structure formed by the above method can adjust the thickness in consideration of the material, performance, etc. of the structure to be formed, in particular, it is preferable to be coated with a thickness of 0.05 to 20 mm with respect to the surface of the structure.

According to the method for forming an insulating structure of the present invention as described above, the protrusion formed by the insulating resin and glass beads on the structure of the road facilities such as coated posts, telephone poles, traffic lights, street lights, traffic signs, control boxes, etc. This can completely prevent the leakage current leakage to the outside due to this, and can prevent the leakage of current due to the aging of the insulating resin due to the high hardness, high weather resistance and high durability of the glass beads. In addition, when contamination such as dust occurs in the unevenness formed by the glass bead protrusions, contaminants can be easily removed by washing with water such as rain or snow, thereby having an excellent effect in fouling resistance. In addition, the insulating structure of the present invention can be easily constructed, has the advantage of improving the physical properties such as weather resistance, stain resistance, scratch resistance, chemical resistance, impact resistance, abrasion resistance of the adhered surface, due to stickers and attachments Contamination can be prevented.
