The present invention relates to a support having an insulation, and more particularly, a support that can be used as a roadbed that requires insulation such as telephone poles, traffic lights, street lights, traffic signs, control boxes, etc., the surface energy is low, the construction is easy It is easy to improve the physical properties such as weather resistance, scratch resistance, chemical resistance, impact resistance, etc. of the surface, and also reduces the insulation effect by blocking the adsorption of air dust and water on the surface due to the uneven structure formed by the beads. And to prevent the illegal advertisements, such as various stickers and posters are bonded to the adhesive, glue, etc. relates to a strut with insulation that can prevent damaging the appearance of the strut.

The roadbed is equipped with a large number of various roadside facilities such as telephone poles, street lights, traffic lights, traffic signboards, control boxes, etc., and these facilities consist of metal pipes, metal pillars, and concrete pillars. The device is installed in the post and powered through the interior. 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 landslides that are installed without grounding in the ground while installing the landslides are irregular, and the wires or circuit breakers installed in the landslides have been used for a long time. And, replacing these aging wires and breakers has a disadvantage that requires 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 post that is a roadbed facility requiring insulation, including telephone poles, traffic lights, street lights, traffic guide signs, control boxes, etc., low surface energy, construction It is easy to improve the physical properties such as weather resistance, scratch resistance, chemical resistance, and impact resistance of the surface, and the insulation effect by blocking the adsorption of dust, moisture and moisture in the air on the surface due to the uneven structure formed by the beads. The purpose of the present invention is to provide a prop that can prevent the reduction of advertises and prevent advertisements such as various stickers and posters from being damaged by the adhesive, glue, or the like.

In order to achieve the above object,

Hollow struts;

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

An object of the present invention is to provide an insulating column comprising a bead layer comprising a plurality of beads which are bonded to an upper 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 column of the present invention is coupled to the upper surface of the hollow insulating support 40, the first insulating resin layer 20 made of a first insulating resin applied to the outer surface of the support 40, the coated first insulating resin And a bead layer 10 formed of a plurality of beads which are made to be protruded to the outside, and in addition, a second insulating water made of a second insulating resin applied to the inner surface of the support 40. It may be configured to further include a layer 30. Through this, the insulation effect can be further increased, and an example of the remedy for this is shown in FIG. 1.

In addition, the upper surface of the coated second insulating resin layer may be configured to further include a bead layer consisting of a plurality of beads coupled to the upper surface of the coated second insulating resin layer and protruding outward from the inside of the support. It may be.

The strut 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 a certain shape, and may have a shape such as a telephone pole, a traffic light, a street lamp, a traffic sign, a control box, etc. The material is not only a conductive material such as metal, but also a concrete material such as concrete or moisture. Because of this possibility of a short circuit accident is included.

The first insulating resin or the second insulating resin used in the present invention is a part that acts as an insulating material of the insulating column, and can be mainly used resins used for exteriors, in particular acrylic resin, ceramic resin, or urethane resin It is preferable to use an acrylic resin, a fluorine resin or an epoxy resin, and more preferably, the first insulating resin uses an acrylic or fluorine resin having weather resistance, and the second insulating resin uses an epoxy resin having good economical efficiency. Use is good considering weatherability and economics.

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.

The first insulating resin layer is formed by applying the first insulating resin on the outer surface of the support, 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 support, the coating method may operate a variety of known methods as described above, specific examples thereof may be painted with a brush, spray , Immersion, etc. may be applied.

In addition, the upper surface of the coated first insulating resin is provided with a concave-convex surface to be bonded to the first insulating resin layer and protrudes to the outside, which makes it difficult to adhere to moisture or water as well as other advertisements and adhesives. It has a bead layer consisting of a plurality of beads.

In the method of forming the bead layer, the first insulating resin as described above is applied to an adhered surface, which is an outer surface of a support, which is a roadbed facility, and the beads are sprayed and cured on top of the insulating resin before the insulating resin is cured. It is possible to form a bead projection through this.

The beads used in the present invention may be spherical, elliptical, or any shape similar thereto, and preferably, spherical beads are formed in a spherical shape by forming bead protrusions on top of the resin binder. It serves to reduce the contact surface between the adhesive and the adhesive. In addition, when air or water enters the unevenness between the bead protrusions formed on the resin binder, air or water spreads to the upper part of the bead, thereby forming an air film or water film, thereby lowering the surface tension of the object. Acts to prevent.

The beads may be sprayed and cured on top of the resin binder, fixed by the resin binder, and protruded from the top of the resin binder to form protrusions.

Various known transparent, translucent, or opaque colorless or colored beads may be used in the form of the beads. Preferably, the beads are transparent beads, which are good for external aesthetic characteristics, and the material may be ceramic beads, resin beads, or the like. Various known beads such as mixtures can be used, preferably glass beads, PMMA beads, zirconia beads or mixtures thereof. This can increase the strength and anti-sticking properties. More preferably, the glass beads are preferably used in consideration of the strength and discoloration of the bead layer, prevention of discoloration, electrostatic properties with the resin binder, and the like.

In particular, the glass beads are obtained by treating glass powder obtained by pulverizing glass, cullet, glass fiber, or glass curet, and the like. The glass composition is compatible with resin binders such as A, C, E, and alkali-resistant glass powder compositions. If it exists, it is not specifically limited.

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 bead may be appropriately selected and used according to the material, use, and the like of the post-attachment surface of the roadbed facility in which the insulating column of the present invention is formed, preferably 0.2 to 3 mm, more preferably 0.3 to It is good that it is 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, if the particle diameter of the beads exceeds 3 mm, the contact surface of the adhered surface and the adhesive is increased, there is a problem that the dispersibility may be lowered.

The bead 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 It is included in 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 are many problems that the beads can be dropped after the insulating column is cured.

Before the insulating resin is cured, the beads sprayed on the insulating resin are cured and fixed by the insulating resin applied to the outer surface of the support as shown in FIG. 1 to protrude from the upper part of the first insulating resin layer 20. A bead layer 10 made of bead protrusions is formed.

In addition, when forming the insulating column of the present invention may be further mixed with the glass powder (glass powder) to 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 beads and the insulating resin so that the beads do not fall off or fall off, and thus the surface to be adhered to the outer wall of the strut, which is a roadbed facility. In addition to moisture and moisture on the surface of the ad can be more effectively prevent the attachment of advertisements and adhesives, such as posters, stickers. In addition, the glass powder suppresses interfacial separation and absorbs and transmits an impact applied from the outside, thereby forming an insulating column 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 that the effect of improving the bonding strength between the bead and the insulating resin is insignificant. If the glass powder is too large, the glass powder cannot be uniformly mixed with the insulating resin, and the strength of the insulating column is reduced or the shrinkage and expansion are increased. The problem is that it can be done.

The glass powder is preferably contained in 20 to 50 parts by weight based on 100 parts by weight of the insulating resin solids. 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 bead and the insulating resin is insufficient, and if the content exceeds 50 parts by weight, the content of the insulating resin is relatively reduced, the insulating paper of the present invention on the adhered surface There is a problem that the adhesion may be reduced.

In addition, when forming the insulating column 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 column.

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 column of the present invention, it is also possible to use a mixture of chopped fiber and 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 column do not occur.

In addition, the insulating column 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.

Insulation support of the present invention having the configuration as described above includes roadbeds, such as telephone poles, traffic lights, street lights, traffic signs, control boxes to which advertising materials or adhesives are attached.

Formation of the insulating column of the present invention is applied directly to the surface of the posts, such as the roadbed facilities, the insulating resin and a mixture of glass powder, glass fiber, or additives as needed, and the mixture containing the coated insulating resin is cured There is a method of adhering and curing the beads on the upper part of the insulating resin by spraying the beads before the process, alternatively directly coating the mixture of the insulating resin and the glass powder, glass fiber, or additives as necessary on the nonwoven fabric, and Before the mixture containing the coated insulating resin is cured, the beads are sprayed, the beads are attached and cured on top of the resin binder, and the non-woven fabric coated with the above components is adhered to the posts of the substructure such as a sticker or sheet type. Method is also possible.

The formation of the insulating column as described above may be formed on the outer wall of the pillars, such as the roadbed facilities already installed, or may be directly formed on the surface thereof while manufacturing the pillars, such as a new roadbed 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 column formed by the above method can adjust the thickness in consideration of the material or performance of the to-be-adhered surface to be formed, and in particular, the thickness is preferably coated with a thickness of 0.05 to 20 mm with respect to the to-be-adhered surface.
