frame;

A resin binder layer made of a resin binder applied to all or part of the outer surface of the frame; And

It provides an exterior frame comprising a glass bead layer consisting of a plurality of glass beads are bonded to the top surface of the coated resin binder layer and protruded to the outside.

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

The exterior frame of the present invention is composed of a frame, a resin binder layer made of a resin binder applied to all or part of the outer surface of the frame, and a plurality of glass beads bonded to the top surface of the coated resin binder layer and protruding to the outside. It comprises a glass bead layer, this configuration is applied to the resin binder on the frame and the surface of the frame and the glass bead projection by spraying and curing the glass beads on the resin binder before the resin binder is cured It can be configured to form a glass bead layer is formed.

The exterior frame of the present invention includes all frames used as frames of various known exterior frames. Specific examples thereof include an exterior frame of a building, an electronic product, a machine, and the like. Examples include interior and exterior chassis, interior and exterior finishing members, exterior frames of electronic devices, and exterior frames of mechanical devices. More specifically, various examples include a PVC / aluminum / steel chassis of a building, a computer monitor exterior frame, and a vehicle exterior molding. Can be.

The resin binder used on the frame surface of the exterior frame of the present invention is a component that acts as a binder, and can be mainly used for exterior packaging. For the convenience of use, the resin binder is preferably a water-soluble resin binder. As a specific example, it is preferable to use resin selected from the group consisting of acrylic resin, ceramic resin, fluorine resin and urethane resin.

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, the resin binder preferably has a viscosity in the range of 1,000 to 10,000 cPs, more preferably around 5,000 cPs for ease of application. In addition, various methods known in the art may be applied as the method of applying the resin binder layer, and specific examples thereof may include methods such as painting with a brush, spraying, and dipping.

The resin binder as described above is applied to the surface of the frame, and the glass beads are sprayed and adhered to the upper portion of the resin binder and cured before the resin binder is cured.

In addition, as the curing method of the resin binder, a variety of known curing methods may be applied thereto. Particularly, the curing method may include natural drying, baking drying, cooling solidification, catalytic curing, ultraviolet curing, and electron beam curing, depending on the type of resin binder (paint). One or more selected from the group can be selected and applied, and this can be applied in various configurations depending on the type of resin binder selected according to the appropriateness of each application and construction method.

The glass bead (glass bead) used in the present invention has a function of reducing the contact surface between the adhered surface and the contaminants by forming a glass bead protrusion on the top of the resin binder in the form of a spherical glass beads. In addition, when air or water enters the unevenness between the glass bead protrusions formed on the resin binder, air or water spreads to the upper glass bead, forming an air film or water film, thereby lowering the surface tension of the object. It acts to prevent adhesion or adhesion of contaminants.

After the glass beads are sprayed and cured on the resin binder, the glass beads may be fixed by the resin binder and protrude from the resin binder to form protrusions. It is obtained by processing the glass powder obtained by grind | pulverizing a cullet, glass fiber, or a glass curette, etc., A glass composition will not be specifically limited if it is compatible with resin binders, 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 bead may be appropriately selected and used according to the material, use, and the like of the frame surface of the exterior frame of the present invention, preferably 0.01 μm to 0.1 mm, and more preferably 0.05 to 1 μm. good. 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 0.1 mm, there are problems such as excessive unevenness or excessively thick coating and dispersibility due to the characteristics of the finish of the product surface.

Glass beads as described above can be used by adjusting the appropriate amount according to the anti-adhesion of the contaminants required, the material of the adhered surface, in particular 10 to 150 parts by weight based on 100 parts by weight of the resin binder solids, more preferably Preferably it is included in 20 to 90 parts by weight. If the content is less than 10 parts by weight, the amount is so small that the effect of preventing pollutants due to contaminants is insignificant. If it exceeds 150 parts by weight, the glass beads after curing because the content is relatively high compared to the resin binder There is a problem that can be eliminated.

As described above, the glass beads sprayed onto the resin binder before curing the resin binder are cured and fixed by the resin binder 2 applied to the adhered surface (frame) 1 as shown in FIG. 2. 2) A glass bead protrusion 3 protruding from the top is formed.

In addition, when the coating surface is formed on the surface of the frame, the resin binder may be further mixed with glass powder and applied to the adhered surface.

The glass powder has a thermal expansion coefficient similar to that of the resin binder, and thus does not cause gaps due to thermal contraction and expansion, thereby improving the bonding force between the glass beads and the resin binder so that the glass beads do not fall off or fall off, thereby contaminating or adhering to the surface of the exterior frame. The adhesion of water can be prevented more effectively. In addition, the glass powder suppresses interfacial separation and absorbs and transmits an impact applied from the outside, thereby forming a coated surface 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 resin binders, such as a glass powder composition, Especially, glass powder of an E-glass composition is more preferable at the adhesiveness with respect to various raw materials.

Although the particle diameter of the said glass powder is not specifically limited, It is preferable that it is especially 0.01 micrometer-1 mm, More preferably, it is 0.05 micrometer-0.7 micrometer. 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 glass bead and the resin binder is insignificant. If too large, the glass powder cannot be uniformly mixed with the resin binder, and the strength of the coating layer is reduced or the shrinkage and expansion properties There is a problem that it can increase.

The glass powder is preferably contained in 20 to 150 parts by weight based on 100 parts by weight of the resin binder solid content. If the content is less than 20 parts by weight, there is a problem in that the binding force between the glass bead and the resin binder is insufficient, and if the content exceeds 150 parts by weight, the content of the resin binder is relatively reduced, so that the adhesion of the coating layer to the adhered surface. There is a problem that this can be degraded.

In addition, when forming the coating surface, the resin binder may further include glass fibers as necessary. The glass fiber acts to increase the tensile strength and crack resistance of the cured adhesion preventer.

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 coated surface, and may be used by mixing the chopped fiber and the pulverized fiber.

The glass fiber is preferably contained in 1 to 100 parts by weight based on 100 parts by weight of the resin binder 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 coating surface do not occur.

In addition, the resin binder may further include additives such as conventional fillers, conductive fillers, pigments, reaction catalysts, thickeners, flow control agents, wetting agents, UV stabilizers, or anti-settling agents, as necessary. In particular, the conductive filler includes a conductive powder and the like, which is included in the resin layer, thereby adding conductivity to thereby suppress static electricity and further increase pollution resistance.

Formation of the coating surface consisting of the above components can be applied to the surface of the various exterior frame in a conventional manner.

That is, the coating surface formation on the exterior frame surface of the present invention is applied directly to the surface of the resin binder and a mixture of glass powder, glass fiber, or additives as needed, and the mixture containing the applied resin binder is cured. Before the process, the glass beads may be sprayed to attach and harden the glass beads on the resin binder.

In addition, such a coating surface may be formed for all or part of the outer surface of the frame.

In addition, the formation of the coating surface as described above may be formed on the surface of the already installed exterior frame, it may be formed directly on the surface while manufacturing the exterior frame.

The resin binder and a mixture of glass powder, glass fiber, or additives as necessary may be selectively used by 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 coating surface (surface combined with the resin binder layer and glass bead layer) formed by the above method can be adjusted in consideration of the material or performance of the surface to be formed to be formed, and in particular, 0.05 to 2.0 for the surface to be deposited. It is preferable to coat to a thickness of mm.

According to the exterior frame of the present invention as described above, the protrusion formed by the glass beads on the surface of the coated exterior frame is formed in an irregular shape, thereby reducing the contact surface between the contaminants, dirt, etc. and the surface surface and the surface tension than the contaminant It can be lowered to prevent their attachment, minimizing contact surface even once attached, and can be easily cleaned or removed even during cleaning or removal. In addition, when contaminants such as dust are formed in the irregularities formed by the glass bead protrusions, contaminants can be easily removed by washing with natural water or wind, such as rain or snow, and thus have excellent pollution resistance. In addition, in the exterior frame of the present invention, the coating surface can be easily constructed, and there is an advantage in that physical properties such as weather resistance, stain resistance, scratch resistance, chemical resistance, and impact resistance of the adhered surface can be improved.

Hereinafter, preferred examples are provided to help understanding of the present invention, but the following examples are merely illustrative of the present invention and the scope of the present invention is not limited to the following examples.

The exterior frame which attached the glass bead protrusion to the urethane resin surface was produced. In addition, the aluminum frame undergoing the coating process as described above with respect to the actual aluminum frame is shown in Figure 2, the aluminum frame is completed as shown in FIG.

As a result of adhering the tape on which the adhesive is formed on one surface of the steel, aluminum and resin exterior frames having the coated surface as described above, the tape did not adhere to the respective steel, aluminum and resin. In addition, the contamination of the steel, aluminum and resin exterior frame having the coating surface formed with graphite and then washed with water was confirmed that the contamination is easily removed.

From this, the exterior frame formed according to the present invention was confirmed that the adhesion prevention function is excellent, and also excellent pollution resistance.

Example 3

In Example 1, 1 kg of urethane resin was uniformly mixed with 1 kg of glass powder having an average particle size of 200 mesh and specific gravity of 2.54, and applied to steel, aluminum, and a resin frame, respectively, followed by the same method as in Example 1. To form a coating surface, and to test whether the contamination resistance with graphite showed a pollution resistance effect equivalent to Example 1 above.

In addition, as a result of observing whether glass beads were dropped by applying external pressure to the coating surfaces formed in Examples 1 and 3, the glass powder was used in Example 3 compared to Example 1, which did not use glass powder. It could be seen that the coated surface exhibits more excellent glass bead binding force.

Example 4

In Example 1, 100 g of pulverized glass fibers having an average fiber thickness of 13.5 μm and an average fiber length of 300 μm were uniformly mixed with 1 kg of a urethane resin, and applied to steel, aluminum, and a resin frame, respectively, the same as in Example 1 above. It was carried out by the method to form a coating surface, and tested whether or not fouling resistance showed a degree of fouling resistance equivalent to Example 1 above.

After coating, the coating was performed in the same manner as in Example 1 to form a coating surface, and tested for contamination resistance, and showed the same degree of adhesion prevention and fouling resistance as that of Example 1.

According to the exterior frame of the present invention as described above, the protrusion formed by the glass beads on the surface of the coated exterior frame is formed in an irregular shape, thereby reducing the contact surface between the contaminants, dirt, etc. and the surface surface and the surface tension than the contaminant It can be lowered to prevent their attachment and, once attached, minimizes contact surface and can be easily cleaned even during cleaning.

In addition, it prevents charging of dust particles due to static electricity by preventing charging on the surface of the exterior frame, and natural rainwater or wind flowing into the micro pores formed by irregularities formed by the glass bead protrusions prevents the surface of the exterior frame surface. When contaminants are generated by pushing contaminants while forming a water film or an air film on the surface, contaminants can be easily removed by washing with rain or snow, and thus have excellent pollution resistance. In addition, in the exterior frame of the present invention, the coating surface can be easily constructed, and can improve the physical properties such as weather resistance, stain resistance, scratch resistance, chemical resistance, impact resistance, etc. of the adherend surface, Blocking corrosion, etc. improves the corrosion resistance and improves the strength of the frame itself has the effect of improving the durability through increased life.

In addition, since the light incident on the surface of the exterior frame is diffusely reflected by the inside of the glass bead or powder, there is an advantage that can give a matte and beautiful exterior surface and design effect when viewed from the outside.
