Description

A double junction glass using bathroom having support frame and manufacturing method thereof

The present invention relates to laminated glass installed in a bathroom of a home or accommodation, and in particular, by shielding the side of the laminated glass with a reinforcing frame including a straight frame and a curved frame to increase the mechanical properties and stability of the laminated glass and damage it It relates to a laminated glass for bathroom provided with a reinforcing frame with a low risk of and a manufacturing method thereof.

In general, a bathroom equipped with a washbasin and a toilet and bathtub is used in a general home or lodging facility. As described above, since the washing facilities, the toilet, and the bathtub are installed together in the bathroom, when a person uses the bathtub for a long time, there is a great inconvenience that other people cannot use the washroom and the bathtub. In addition, when the size of the bathroom at home or accommodation is small, only a washbasin and a toilet are installed, and a shower facility for showering is installed at a predetermined position on the wall of the bathroom. Similarly in this case, when taking a shower in the bathroom, other people cannot use the washbasin or toilet, and when taking a shower in a narrow bathroom, water scatters everywhere, making the entire bathroom wet.

In order to solve the above inconvenience, in modern apartments or accommodations, a bathroom or shower is installed independently of a washbasin or toilet. In this way, when a bathroom or shower facility is installed independently, if the area of a home or accommodation is large, a bathroom or shower facility can be installed in a separate space, but in most cases, a shower booth for a simple shower is provided in the bathroom. made and used

Most of the shower booths currently in use are made of glass materials in consideration of aesthetics. The glass used for the shower booth uses one layer of tempered glass or laminated glass laminated with two or more layers of tempered glass, and by connecting the tempered glass using a predetermined connecting device, the shower booth is in the form of a square box in the corner of the bathroom. will be completed In addition, a door made of tempered glass is installed using a predetermined hinge means.

However, in the case of the glass plate that makes up the door or shower made of tempered glass, the strength is very good and there is no risk of breakage. damage may occur. In addition, due to the characteristics of laminated glass, when an external force is applied to the side part, the glass laminated by the external force may fall apart or cause a scratch, and the glass may be easily damaged around this scratch. Not only is it not good for the user, but the edges formed on the side are quite sharp, so if you make a mistake, it may give the user a cut.

In addition, when the tempered glass is broken and falls, if it falls on the foot of a person, it can cause great damage, and also can cause great damage to a person when the tempered glass scatters through various manipulations.

In order to solve such a drawback, sheet paper is sometimes attached to one side of tempered glass, but when the tempered glass is broken, the sheet paper does not properly hold all of the glass pieces, so that the glass pieces are scattered.

A method for manufacturing laminated glass for bathroom provided with a reinforcing frame according to the present invention,

a) forming on the inside along the longitudinal direction, preparing a side frame having a guide groove composed of a body portion and a pair of extension portions;

b) painting the surface of the side frame;

c) Inserting the laminated glass into the side frame, bending or cutting a certain part to abut both ends of the side frame to shield all of the side surfaces and parts of the front and rear surfaces of the laminated glass to do; and

d) coupling a connection frame to a portion where both ends of the side frame meet to shield a portion of the outer surface of the side frame;

may include

In the present invention, step a) is a step of preparing a reinforcing frame, and the reinforcing frame may include a side frame.

In the present invention, in more detail in step a),

a1) extruding aluminum to form a plate material having a guide groove having a 'U'-shaped cross section perpendicular to the longitudinal direction;

a2) cutting the extruded plate material to a predetermined size; and

a3) bending a certain portion of the cut plate material so that the opened side of the guide groove is inside, and forming the shape of the surface in contact with the front and rear surfaces of the laminated glass into an arc shape;

may include

In the present invention, step a1) is a step of extruding aluminum to form a plate having a 'C'-shaped cross-section and a rectangular (bar) shape as shown in FIG. 3(a).

That is, in step a1), one body portion 130 and a pair of extension portions 140 formed at opposite ends of the body portion are formed by injecting a liquid aluminum molding liquid in the longitudinal direction of the extrusion mold and processing it integrally. ) may be provided to form a guide groove 120 having one surface opened by the body portion and the extension portion. This increases the rigidity of the side frame while forming the body portion, the extension portion and the guide groove at the same time, and allows the side frame to have a certain shape and size.

In the present invention, the size and thickness of the side frame are not limited, but in the case of thickness, it is preferable to be molded to a thickness of 1 to 3 mm in consideration of assembling and compatibility with laminated glass, the purpose of protecting the laminated glass, and the like. In addition, in the case of the size, the length in the width direction may be 20 to 40 mm, and the length in the longitudinal direction may be 500 to 5,000 mm, but the present invention is not limited thereto.

In addition, the size of the body portion and the extension portion, and the depth of the guide groove may all be determined according to the thickness of the laminated glass and the formation position of the width and length of the plate material. In the present invention, the length of the body portion is preferably formed to be 0.2 mm or less larger than the thickness of the laminated glass, preferably 8 to 10 mm. In addition, maintaining the size of the extension part 15 to 20 mm based on the sum of the thicknesses of the body part can secure adhesion with the laminated glass, and the bending, breakage, etc. of the extension part according to the mass of the laminated glass can be prevented. It's good to be able to prevent it.

As described above, a guide groove having a 'C' shape in cross section is formed through the body and the extension, so that when the laminated glass is inserted into the guide groove, the body and the extension include all side surfaces of the laminated glass, the front and A part of the back surface is covered to protect the laminated glass from impact and to make installation easier.

In the present invention, the step a2) is a step of cutting the side frame extruded through step a1) to a certain size, in accordance with the size of the laminated glass to be combined with the aluminum side frame extruded in a straight line along the longitudinal direction. The length can be set, and the side frame can be cut according to the length to proceed.

That is, in step a2), the length of the side frame may be determined by the side length of the laminated glass. In this case, if the side length of the laminated glass is A, the overall length of the side frame is adjusted to about 0.9A to 0.99A during bonding. It is preferable because the position of the side frame can be flexibly adjusted.

Next, step a3) is a step of bending a certain part of the side frame according to the side of the laminated glass when the side of the laminated glass is curved in some cases. After arbitrarily setting the part to be combined with the curved side part, the part may be bent and processed in a curved shape in the same way as laminated glass.

That is, step a3) bends the portion including both ends at a predetermined angle in the same direction to manufacture a curved frame so as to completely cover the remaining side portions that are not covered by the side frame in the laminated glass, As shown in FIG. 1 , both ends of the frame having the guide groove formed thereon in the longitudinal direction may be bent in a direction facing each other so that the opened side of the guide groove is inside.

In step a3), all methods used for bending processing of general metal materials such as the side frame of the present invention, such as cold working and heat forming, can be applied, preferably at room temperature as in Korean Patent Registration No. 10-0299766. It is recommended to apply a cold working method that causes plastic deformation in the material by applying mechanical force using a draw bending device including a bending roller and a hydraulic press.

3 and 4 will be described in more detail, the first prepared side frame 110 is fixed to the guide groove and the rotational bending portion 310 is formed with irregularities that can accommodate the extension. At this time, the side frame is fixed so that the opened portion of the guide groove faces the center of the rotation bending part. And the pressure die 330 on the outer surface of the side frame and the clamp die 320 spaced apart from the pressure die by a predetermined distance are positioned to press the outer surface of the side frame.

The pressure die receives the force through the pressing member 340 and presses the side frame in the direction of the arrow A in FIG. Press the side frame with And when the clamp die and the rotation bending part are rotated in the direction of arrow B with the center of the rotation bending part as an axis, the side frame is pulled in the direction of arrow B according to the rotation of the rotation bending part and the clamp die while supported by the pressure die The shape of the surface in contact with the front and rear surfaces of the laminated glass may be formed in an arc shape while being formed.

In this case, since curved bending is possible with a single mold, the manufacturing process is simple, the mass productivity and reproducibility are excellent, and above all, the body so that the unevenness formed in the rotating bending part does not deform the width of the guide groove. By holding the part and the extension part, it is possible to maintain a constant distance from each other on all sides of the extension part which are opposed to each other.

In addition, the reinforcing frame may further include one or a plurality of adhesive receiving grooves 150 on the inner surface of the guide groove.

In the adhesive receiving groove, the adhesive used when inserting and fixing the laminated glass into the reinforcing frame is used excessively or when the laminated glass is applied by applying excessive pressure toward the body of the reinforcing frame, the adhesive is pushed out of the reinforcing frame by the pressure. In order to prevent the case from coming out, as shown in FIG. 5 , one or more may be provided on the inner surface of the guide groove, more specifically, on the inner surface of the extension 140 .

When the adhesive receiving groove is provided as described above, the adhesive is positioned between the laminated glass and the reinforcing frame as shown in FIG. Since there is more than the part, the adhesive force between the laminated glass and the reinforcing frame can be further increased. The original purpose here is to prevent the applied adhesive from escaping out of the reinforcing frame or, more precisely, out of the guide groove, thereby improving the aesthetics and improving workability.

After preparing the reinforcing frame as described above, the surface of the reinforcing frame may be painted (step b)).

In the present invention, step b) does not limit the coating method and the coating material used during coating. For example, the coating method may include liquid coating, powder coating, baking coating, etc., which are general painting methods, and in addition, plating, case hardening, and chemical treatment rather than painting. All surface treatment methods including coating), anodizing, lining, etc. may be applied, but the present invention is not limited thereto.

Among these, the general coating method is described in more detail, after preparing a liquid composition by mixing a paint and a solvent, directly painting it or spraying it with liquid painting, placing the paint powder on the frame surface, and then applying heat to the frame. Powder coating to naturally melt the paint on the frame surface to form a coating layer, and baking coating in which heat is applied once more to the frame on which the coating layer is formed as described above to dry it. Among these, powder coating It is preferable because it is possible to increase the corrosion resistance of the frame and the adhesion and durability of the coating layer, and to obtain a coating layer having a uniform thickness.

In the present invention, the painting method may proceed with the painting operation twice or more if necessary. That is, two coats of the undercoat and the top coat or three coats of the undercoat, the middle coat and the top coat can be carried out.

In the present invention, in the coating operation, the composition (primary coating composition) used for undercoating and the composition (secondary coating composition) used for intermediate or topcoating may be different from each other.

The primary coating composition is formed between the conductive material and the secondary coating composition and blocks the moisture remaining inside the conductive material from reacting with the secondary coating composition, thereby further enhancing the weather resistance of the coating film, urethane resin, epoxy resin and any one or two or more selected from acrylic resins.

An example of the urethane resin may include one or a plurality of mixtures selected from polycarbonate polyol, ester polyol, acrylic polyol, ether polyol, and caprolactone.

The polycarbonate polyol may be prepared by a known method, and the polycarbonate polyol may include a reaction between an aliphatic or aromatic polyol and phosgene and a transesterification reaction of a carbonic ester. The production method of aliphatic polycarbonate polyol is generally produced by transesterification of carbonic ester. In addition, Belgian Patent Publication No. 630,530 (1963) discloses a method for preparing a high molecular weight polycarbonate polyol having a narrow molecular weight distribution from a cyclic carbonate. For example, it can be obtained by a substitution reaction of ethylene glycol carbonate with a diol having various structures. The polycarbonate diol is commercially available, and preferably, Carb 100 manufactured by Ube, Japan may be used.

The caprolactone polyol is a polyester polyol obtained by ring-opening polymerization of ε-caprolactone using a polyol initiator or polyamine initiator, and the polyol initiator includes, for example, ethylene glycol, propylene glycol, 1,4-butylene glycol, 1, diols such as 3-butylene glycol, 1,6-hexanediol, neopentyl glycol, bisphenol A and resorcin; triols such as glycerin, 1,2,6-hexanetriol, and 1,1,1-tris(hydroxymethyl)propane; For example, tetraols, such as pentaerythritol, erythritol, and methylglucoxide; For example, hexaol, such as sorbitol and dipentaerythritol; For example, octanol, such as sucrose, etc. are mentioned.

The polyester polyol may be a polyester polyol prepared by reacting a polyol with an acid. In a preferred embodiment of the present invention, the polyester polyol is obtained by reacting a polyol such as ethylene glycol, neopentyl glycol, or hexanediol with an acid such as isophthalic acid, adipic acid, or azelic acid to provide peel resistance to the metal deposition layer. It can be prepared using an ester polyol prepared by

The acrylic polyol is a monomer having a hydroxyl group in the form of vinyl, for example, a compound selected from 2-hydroxyethyl acrylate, 2-hydroxyethyl methacrylate, 2-hydroxybutyl acrylate, hydroxypropyl methacrylate, etc. It is a polyol produced using The method for preparing the acrylic polyol is known in Korean Patent Application No. 10-199-18863 and the like, and is commercially available. Preferably, an acrylic polyol having a molecular weight of 800 to 6,000, more preferably 1,000 to 3,000, manufactured by Soko Chemical of Japan may be used.

Examples of the epoxy resin include bisphenol A, bisphenol F, bisphenol S, novolak-based glycidyl ether type, glycidyl ester type, glycidyl amine type, dicyclopentadiene skeleton type, biphenol type, etc. can be heard Bisphenol A, bisphenol F, and novolac-based resins are suitably used as these resins in the balance between economy and performance.

The epoxy resin suitably has a softening point of 30 to 160 ℃, preferably 50 to 150 ℃, particularly preferably 60 to 150 ℃ from the viewpoint of workability and handleability. If the softening point of the epoxy resin is less than 30° C., it is difficult to maintain the object at room temperature, and it is not preferable for use in powder coatings. On the other hand, when the softening point exceeds 160° C., the reaction temperature in the kneader in melt-kneading is higher than the reaction temperature, which seriously affects the coating film performance, so it is not preferable.

Moreover, as an equivalent of an epoxy resin, it is generally 600-2000 g/equivalent, Preferably, it is suitable that it is 600-1500 g/equivalent. In addition, it is suitable that the phase transition temperature of an epoxy resin is 20 degreeC or more, Preferably it is 30 degreeC or more, Especially preferably, it is 40 degreeC or more. When the phase transition temperature is less than 20 ° C., when stored at room temperature, it is not preferable because the composition deteriorates such as blocking.

An example of the acrylic resin is a glycidyl group-containing acrylic copolymer, more specifically glycidyl acrylate, glycidyl methacrylate, methyl glycidyl methacrylate, methyl glycidyl acrylate, 3, Any one or a plurality of glycidyl group-containing monomers selected from 4-epoxycyclohexylmethyl (meth) acrylate and acryl glycidyl ether;

The primary coating composition or the secondary coating composition may be added by changing a crosslinking agent, a catalyst, etc. according to the included resin. For example, in the case of a urethane resin or an acrylic resin, it can be coated in a one-component manner without a separate crosslinking agent to form a coating film, and if necessary, a metal catalyst such as zinc can be further added to increase the curing speed.

In the case of the secondary coating composition, polypropylene resin and polar group-containing resin may be added in addition to the above resins in order to easily control the thickness of the coating film. Examples of the polypropylene resin include homopolypropylene and a copolymer of propylene and α-olefin having 2 or 4 to 10 carbon atoms.

The polar group-containing resin is added to improve adhesion to a base material such as a metal, and examples of the resin include a resin containing an amide group, a hydroxyl group, a carboxyl group, and the like in a branched chain. Examples of these include acid-modified polypropylene, ethylene acrylic acid copolymer, and ethylene methacrylic acid copolymer.

Further, the modifier may include a thermoplastic resin such as petroleum resin, urea aldehyde resin, terpene, polyolefin, and the like. In addition, the type of resin used in the secondary coating composition may vary depending on the performance required. For example, when weather resistance is required, an acrylic resin or a fluorinated acrylic resin, mainly isophthalic acid and neopentyl glycol A hydroxyl-terminated polyester resin composed of a condensate, a resin such as a fluororesin containing a hydroxyl group, etc. can be further added, and when flexibility is required, the hydroxyl-terminal composed mainly of a condensate of terephthalic acid and ethylene glycol A polyester resin, a polyisocyanate compound, an epoxy resin, and a phenol curing agent having 1.5 or more phenolic hydroxyl groups per molecule may be further added.

The primary coating composition may include 0.1 to 50 parts by weight of a curing agent, 0 to 100 parts by weight of a pigment, and 0.1 to 10 parts by weight of an additive based on 100 parts by weight of the total resin.

In addition, the primary coating composition or the secondary coating composition may have a different manufacturing method depending on the application form. First, when a liquid composition is applied to the surface of an object, such as the primary paint composition, it can be used immediately after mixing the composition and the solvent at room temperature. It is preferable to knead the composition using a single screw or twin screw extruder, prepare it in pellet form, and then pulverize it to an appropriate particle size using a pulverizer such as a pin mill. In this case, the particle size of the powder coating is preferably 10 to 200 μm.

If the particle size of the powder coating is less than 10 μm, the smoothness of the coating may decrease, and the thickness of the coating film may decrease significantly, resulting in a significant decrease in physical properties.

In the present invention, step c) is a step of shielding all of the side surfaces and a portion of the front and rear surfaces of the laminated glass by inserting the laminated glass into the guide groove formed in the side frame, and is set to abut both ends of the side frame. It can be carried out by bending (切曲) or cutting (切斷) parts.

In the present invention, step c) may be performed differently depending on whether the side frame is bent or cut. First, in the case of bending the side frame, as shown in FIG. 5, a portion of the extension part constituting the guide groove of the side frame is cut in a 'V' shape from the opened side of the guide groove toward the body to form a bent groove. After that, it can proceed by bending so that the cut surfaces of the bending grooves abut each other.

In this case, in the method of bending the side frame, the prepared side frame is first placed on a fixing jig, and an arbitrary bending line composed of a pair is set on the bending surface so as to be parallel to the longitudinal direction. In this case, the bending lines may be configured to be spaced apart from each other by a predetermined distance. Next, as shown in FIG. 5 (b), the bending grooves 113 are formed at both ends of the plate in the same direction along the bending line. That is, to form a bent groove cut in a pair of 'V' shape parallel to the longitudinal direction on one surface of the frame.

In general, when a bending moment acts on both ends of a member in the same direction, a proof force is generated in the member to resist the bending moment, which is referred to as a bending stress. The bending stress is again based on the direction in which the bending moment is applied, and a compressive stress is generated on the surface facing the same direction as the direction, and a tensile stress is generated on the opposite surface.

The problem is that when a compressive or tensile stress is generated in a member having the same mass and volume, deformation may occur in the member. In particular, compared to tensile stress, compressive stress gives a greater deformation to the member than tensile stress due to the characteristic of a solid that is difficult to generate density deformation in the same volume. can

The bending groove minimizes the deformation of the plate material due to the compressive stress, thereby preventing damage to the plate material itself due to the deformation and preventing damage to the laminated glass to be inserted later.

As shown in FIG. 5 , the bending groove 113 first sets an arbitrary bending line (not shown) parallel to the longitudinal direction at a distance spaced apart from the edge in the longitudinal direction on one surface of the plate. In this case, the bending lines may be configured to have the same size and to be spaced apart from each other by a predetermined distance. And along the bending line, a pair of bending grooves are formed in a 'V' shape as shown in the drawing.

When the bending groove is bent, the inner surfaces of both sides of the bending groove are closely coupled to each other, thereby maintaining the upwardly bent state. In this case, the inner surfaces of both sides of the bending groove may be bonded by applying an adhesive in advance, or may be coupled by an adhesive applied when the laminated glass is inserted later.

In the present invention, the bent groove is not limited in size, depth, angle, and the like. However, if the thickness of the bent part is thick, the remaining body part may be broken when the part is bent, and if the bent part is thin, there is a risk of tearing the part when bending. It is important to set appropriately considering the ductility, compressive stress, bending strength, etc.

In addition, even in the case of the angle (inner angle, DEG in FIG. 5) formed by the inner surface of the bending groove, it is preferable that the body portion and the extension portion do not interfere with the laminated glass when the laminated glass is inserted. The bending angle of the frame can form a right angle or a fine obtuse angle, so that the laminated glass can be easily inserted and completely wrapped. The adhesive used when bonding the laminated glass moves between the inner surfaces, so that adhesion can be achieved naturally.

As a portion of the side frame is upwardly bent using the bending groove in the arrow direction of FIG. 5 , the side frame may increase adhesion to the laminated glass at a portion where the side portion of the laminated glass forms a right angle. Through this, the side frame holds the laminated glass more firmly in the corresponding part, thereby increasing the mechanical strength, and even when the laminated glass is damaged, it is possible to prevent the generation of scattered fragments, thereby protecting the safety of the user.

In addition, when the side frame is completely cut, it can be cut in a shape similar to that of the bent groove of FIG. 5 . That is, by completely cutting the extension part and the body part constituting the guide groove of the frame in a 'V' shape in the direction of the body part from the opened side of the guide groove, two straight frames 111 and one curved frame ( 112), the cut surfaces of the straight frame and the curved frame may be joined to each other.

That is, in this case, the frame is divided into three as shown in FIG. 2 , and the straight frame is composed of two and wraps one side of the laminated glass and is coupled to a position opposite to the fixing target, and the curved frame is the laminated glass. It may be provided so as to surround the other side of the side to which the straight frame is not coupled.

In this case, the straight frame and the curved frame formed by cutting the side frame may be cut so that both ends in the longitudinal direction have an oblique shape.

7 and the like, the straight frame and the curved frame are characterized in that both end surfaces in the longitudinal direction in contact with each other are butt jointed in an oblique shape. That is, since both ends of the straight frame and the curved frame have slanted junction surfaces cut at an angle of a certain angle, especially in the case of a straight frame, the straight frame may be configured in a long trapezoidal shape as a whole.

As for the inclined joint surface, all the reinforcement frames are inclined in the same direction, and in detail, the inclined joint surface where the straight frame 111 and the curved frame 112 contact each other as shown in FIGS. 7 and 8 is when viewed from the front. In the plane to the bottom direction (from the inner opening of the frame to the outer body), an oblique surface is formed, and at this time, the outer body and the inclined joint surface are formed to be inclined at an angle of 45°, so that each straight frame and a curved surface are formed. When the inclined joint surfaces of the frame are in contact with each other, they fit exactly without interference, so that a strong connection can be made without structural weakness.

When the side frame is cut into three pieces and combined with the laminated glass as described above, the process of bonding the portion where the straight frame and the curved frame meet may be further performed.

The method of bonding the part where the straight frame and the curved frame meet is not limited in the present invention, and for example, an adhesive is applied to the inclined joint surface where the frame and the frame are joined, and then cured after bonding, or the inclined joint surface Adhesive can also be inserted and cured in the gap between them. When an adhesive is not used, the inclined joint surface may be welded to be physically completely combined.

In the present invention, as a joining method for joining the straight frame and the curved frame, in more detail, a method of welding an inclined joint surface may be mentioned. However, in this case, the reinforcing frame to be joined may further include a welding groove 114 on the inclined joint surface in order to more firmly join the straight frame and the curved frame.

7 and 8, the inclined joint surface of the straight frame and the curved frame, that is, the butt joint surface, may further include a welding groove having a structure in which the outer edge is cut to a predetermined size when joined. . At this time, the welding groove is cut in a direction perpendicular to the body portion in the drawing, but it is not necessarily cut vertically, and the angle between the welding groove and the body portion may be an acute angle or an obtuse angle. In addition, the size of the welding groove is not limited, and as an example, as shown in FIG. 7 , cut to a size of 0.1 to 5 mm based on the edge in direct contact with the fixing target among the edges of the butt joint surface to form the thickness of each frame and It is preferable that the cut surface is formed so as to be parallel.

As the welding groove 114 is provided on both the inclined joint surfaces of the straight frame and the curved frame as described above, the straight frame and the curved frame do not directly contact each other but are spaced apart from each other by a certain distance. Thereafter, when butt welding is performed between the welding grooves as shown in FIG. 8 , a welding portion W is formed so that the straight frame and the curved frame can be joined to each other.

That is, in the straight frame and the curved frame, since the welding grooves are positioned side by side at the same height with respect to the ground, it is possible to prevent the molten metal from flowing down during single-sided welding or the welding surface from being uneven. In addition, since the welding groove is directly welded as described above, the straight frame and the curved frame can be perfectly fixed even though the welding range is minimized, so it is possible to suppress the increase in cost due to the addition of the process, and the fatigue strength after welding is lowered can prevent

In the present invention, the welding is performed while the welding grooves are positioned side by side at the same height as described above, and the welding method is not limited, but gas metal arc welding (GMAW) and flux-cored arc welding are performed. It is recommended to proceed with welding (Flux Cored Arc Welding, FCAW).

In addition, in step c), the side frame inserts the laminated glass into a guide groove provided in the frame to bond with the laminated glass, and after applying an adhesive to the inside of the guide groove, the laminated glass can be inserted there is.

In the present invention, the type of the adhesive used in step c) is not limited, and may preferably be silicone, epoxy, or a mixture thereof.

The silicone-based adhesive may use any resin used to adhere an inorganic material while including a silicon (Si) component, and in detail, may be prepared by reacting a monomer having a functional group with a silicone monomer.

The siloxane-based monomer having the functional group includes hexamethylcyclotrisiloxane, octamethylcyclotetrasiloxane, decamethylcyclopentasiloxane and dodecanemethylcyclohexasiloxane, and the functional group-containing monomer is polyglycidyl epoxide, Aliphatic glycidyl ether, aromatic isocyanate, aliphatic isocyanate, dimethylaminoethyl methacrylate, acrylamide, N-aminohexyl acrylate, heptyl acrylate, hydroxyethyl acrylate, hydroxylpropyl methacrylate, Acrylic acid, glycidyl methacrylate, monoethanolamine, diethanolamine, etc. are mentioned.

In addition, the silicone-based adhesive may further include an acrylic monomer having a vinyl group in order to further improve adhesive strength during the preparation of the composition. Examples of the acrylic monomer include dimethylaminoethyl methacrylate, heptyl methacrylate, N-hexyl acrylate, heptyl acrylate, hydroxyethyl acrylate, hydroxylpropyl methacrylate, and glycidyl methacrylate. can be heard

In addition, the silicone-based adhesive is dibenzoyl peroxide, di(4-tert-butyl peroxide), dicumyl hydroperoxide, 2,2-azodi(isobutyronitrile), dilauroyl peroxide, di(4 A polymerization initiator such as -tert-butyl cyclohexyl) peroxydicarbonate, dicumyl peroxide, and di(2-ethylhexyl) peroxydicarbonate may be further included.

The epoxy-based adhesive may be any resin exhibiting an adhesive action upon curing, particularly a bifunctional resin having a weight average molecular weight of 5,000 or less, preferably 3,000 or less. In order to improve the fluidity during lamination, a bisphenol A or bisphenol F liquid epoxy resin having a weight average molecular weight of 500 or less is particularly preferred.

A curing agent commonly used as a curing agent for the epoxy resin may be used as a curing agent for an epoxy resin in the present invention, and examples of the curing agent include amines, polyamides, acid anhydrides, polysulfides, boron trifluoride, and two or more per molecule. There are compounds having a phenolic hydroxyl group, such as bisphenol A, bisphenol F and bisphenol S. Phenolic novolac resins, bisphenol novolac resins and cresol novolac resins are particularly preferable because of their excellent corrosion resistance upon water absorption. These resins preferably have a weight average molecular weight of 500 to 2,000, specifically 700 to 1,400.

In addition, the adhesive may further include a coupling agent for moisture curing in addition to the above components. The coupling agent is focused on the fact that the place of use of the laminated glass according to the present invention is a bathroom with a lot of moisture. A much better adhesive strength can be provided between the and reinforcing guides.

The coupling agent is an epoxy group, an amino group, an imino group, an isocyanate group, a vinyl group, a styryl group, a methacryloxy group, an acryloxy group, a ureido group, a chloropropyl group, What has a functional group such as a mercapto group and a sulfido group, for example, γ-glycidoxypropyltrimethoxysilane, γ-glycidoxypropyltriethane Epoxysilane compounds, such as oxysilane, γ-glycidoxypropylmethyldimethoxysilane, β-(3,4-epoxycyclohexyl)ethyltrimethoxysilane, and γ-glycidoxypropylmethyldiethoxysilane; γ-urethane; Ureidosilane compounds such as idopropyltrimethoxysilane; γ-aminopropyltrimethoxysilane, γ-aminopropyltriethoxysilane, γ-aminopropylmethyldimethoxysilane, γ-aminopropylethyldiethoxysilane, bis Trimethoxysilylpropylamine, bistriethoxysilylpropylamine, bismethoxydimethoxysilylpropylamine, bisethoxydiethoxysilylpropylamine, N-β(aminoethyl)γ-aminopropyltrimethoxysilane, N -β(aminoethyl)γ-aminopropylmethyldimethoxysilane, N-β(aminoethyl)γ-aminopropyltriethoxysilane, N-β(aminoethyl)γ-aminopropylethyldiethoxysilane, 3, 3 -Aminosilane compounds, such as dimethyl-4-aminobutyltrimethoxysilane and 3,3-dimethyl-4-aminobutylmethyldimethoxysilane; (N-cyclohexylaminomethyl)methyldiethoxysilane, (N-cyclohexyl and aminomethyl)triethoxysilane, (N-phenylaminomethyl)methyldimethoxysilane, and (N-phenylaminomethyl)trimethyloxysilane, and these may be used alone or in combination of two or more.

When the coupling agent is used with an adhesive having a reactive group that reacts with a functional group, the effect is doubled. Such an adhesive is an adhesive having an epoxy group, an amino group, an imino group, an isocyanate group, a vinyl group, a styryl group, a methacryloxy group, an acryloxy group, a ureido group, a chloropropyl group, a mercapto group, a sulfido group, etc. It is preferable to use the vinyl group by mixing it with a silicone adhesive or an epoxy adhesive in which the monomer is mixed.

As shown in FIG. 6, the adhesive used in step c) may be put into the guide groove in the form of a liquid or a solid having moldability, and then the adhesive is pressed in the insertion direction while the laminated glass is inserted, through which the adhesive is Naturally, curing is performed while filling the space between the guide groove and the laminated glass.

Step c) differs depending on the components of the adhesive, but may be cured by irradiating heat or UV for curing, and the present invention is not limited thereto.

In the present invention, the laminated glass is made by bonding two or more glass plates, and if necessary, a polymer resin including a polyvinylbutyral film or other adhesive having a high modulus of elasticity is placed between the glass plates and adhered with heat and pressure. It refers to safety glass manufactured so that fragments do not scatter even when broken.

In the present invention, the laminated glass basically laminates two sheets of glass (a first glass and a second glass) as shown in FIGS. 9 and 10, but a mesh layer ( 230) and an adhesive layer 240 for bonding the mesh layer and the first glass or the second glass is further provided.

In the present invention, the first glass 210 or the second glass 220 constitutes the outermost layer of the laminated glass, that is, the uppermost layer and the lowermost layer, and general glass may be applied to each, but of the laminated glass. In order to improve stability by improving mechanical strength and thermal durability, it is preferable to use tempered glass having superior mechanical strength and thermal durability compared to general glass.

The adhesive layer 240 may be positioned between the first glass and the second glass, and is provided for bonding the mesh layer and the mesh layer, the mesh layer and the first glass, or the mesh layer and the second glass. .

There may be various resins used for the adhesive layer, but polyvinyl butyral (PVB) is the most commonly used in terms of physical properties, performance, or manufacturing, and in addition, ethylenevinyl acetate (Ethylenevinyl Acatate, EVA) ) or a thermoplastic polyurethane resin (Thermoplastic Polyurethane, TPU).

The polyvinyl butyral (PVB) resin is manufactured by butylation of polyvinyl alcohol, and may enable a required level of adhesion by controlling the degree of butylation when bonding to glass. However, PVB resin is very tough and has high hardness, so it is not easy to use when manufacturing laminated glass even if it is manufactured in a plate shape. becomes difficult to obtain. For this, it is necessary to add an appropriate level of plasticizer to form a flexible film, and various additives are included depending on the field of application, required performance, and laminated glass manufacturing method. Accordingly, thickness, adhesion, color, and surface roughness etc. are different.

In addition, the ethylene vinyl acetate (Ethylenevinyl Acatate, EVA) has a strong characteristic to humidity, and is weak to moisture, which is a disadvantage of the PVB film. can solve Since the EVA film is relatively resistant to humidity, higher safety can be ensured even when used in an environment with high humidity, such as a shower booth. In addition, since it is relatively inexpensive in terms of price, the range of application can be further expanded.

More preferably, ethylene vinyl acetate is used as the composition for forming the adhesive layer. This is because the use of the laminated glass according to the present invention is a bathroom with high humidity, so it is preferable in terms of safety to use ethylene vinyl acetate, which has higher humidity resistance than polyvinyl butyral.

In addition, the composition for forming the adhesive layer may further include one or a plurality of phase change materials in order to secure thermal insulation and dimensional stability with respect to temperature.

The phase change material refers to a material that stores or emits heat while changing the shape of the material from solid to liquid, from gas to liquid, from liquid to gas as the temperature changes, and if it is commonly used in the art, it is a type Not limited to, liquid and solid, as well as organic and inorganic materials can be used.

The organic phase change material may include, for example, polyethylene glycol, polyethylene oxide, polyvinyl alcohol, paraffin, vinyl stearate, and the like, and it is preferable to use paraffin. However, in the case of paraffin, the phase change temperature is around 30° C. and most of it exists in a liquid phase, so it is preferable to encapsulate the solid organic material as a shell and include it.

As the inorganic phase change material, for example, alumina, silica, titania, zirconia, chromite, zircon oxide, magnesium oxide, magnesium hydroxide, aluminum hydroxide Silicon carbide, titanium carbide, silicon nitride, aluminum nitride, boron nitride, ceria, MgCl ₂ 6H ₂ O, Al ₂ (SO ₄ ) ₃ 10H ₂ O, NH ₄ Al(SO ₄ ) ₂ ·12H ₂ O, KAl(SO ₄ ) ₂ ·12H ₂ O, Mg(SO ₃ ) ₂ ·6H ₂ O, SrBr ₂ ·8H ₂ O, Sr(OH) ₂ ·8H ₂ O, Ba(OH) ₂ ·8H ₂ O, Al(NO ₃ ) ₂ ·9H ₂ O, Fe(NO ₃ ) ₂ ·6H ₂ O, NaCH ₂ S ₂ O ₂ ·5H ₂ O, Ni (NO ₃ ) ₂ ·6H ₂ O, Na ₂ S ₂ O ₂ ·5H ₂ O, ZnSO ₄ ·7H ₂ O, CaBr ₂ ·6H ₂ O, Zn(NO ₃ ) ₂ ·6H ₂ O, Na ₂ HPO ₄ ·12H ₂ O, Na ₂ CO ₃ ·10H ₂ O, LiNO ₂ ·3H ₂ O, and CaCl ₂ ·6H ₂ O may be included, among which MgCl ₂ ·6H ₂ O is particularly preferred.

The inorganic phase change material as described above has advantages in that it has a higher density than the organic phase change material, and has a large amount of latent heat and thus has better heat absorption performance. In addition, it has excellent corrosion resistance, which contributes to prolonging product life. On the other hand, the latent heat capacity is inevitably smaller because the organic phase change material must be used in microencapsulation due to its nature, but since the inorganic phase change material can be directly mixed with the resin and used, there is a limitation in using the organic phase change material will be able to overcome The inorganic phase change material may be in powder form other than the above-listed hydrate form.

The mesh layer 230 is a mesh-shaped mesh bonded between the first glass and the second glass, and while improving aesthetics and mechanical strength of the laminated glass, the first glass and the second glass Prevents glass fragments from scattering when glass is broken. That is, when an impact is applied to the laminated glass by natural disasters such as earthquake, typhoon, tsunami, or artificial force of a person, the laminated glass is prevented from being easily damaged, and even if broken, glass fragments are prevented from scattering in all directions can do.

In the present invention, the mesh layer may be a metal mesh, more specifically, a mesh layer made of aluminum, and the metal mesh layer made of aluminum as described above is relatively light compared to other metals while ensuring a certain mechanical strength, and corrosion Structural stability is excellent, and it is not significantly affected by the characteristics of a humid bathroom.

In addition, the mesh layer may further include a decorative layer 250 of general fibers, particularly natural fibers or synthetic fibers, knitted fabrics, and non-woven fabrics as shown in FIG. 10 . This has the effect of protecting the privacy of the user by giving an aesthetic feeling and opacity such as a pattern to the laminated glass separately from the metal mesh layer.

The fibers constituting the decorative layer may be more preferably kenaf fibers. The kenaf fiber ( Kenaf, Hibiscus cannabinus L. ) is an annual herbaceous fiber crop native to West Africa and has a fast growth characteristic. The kenaf fiber has high rigidity and light weight, and above all, has very high dimensional stability against moisture, so that it does not affect the mechanical properties of laminated glass even in a bathroom with high humidity.

However, since kenaf fiber has a higher content of components such as pectin, hemicellulose and lignin (hereinafter referred to as “non-cellulose”) compared to other bast fibers, the strength and durability must be removed by removing the non-cellulose component. This reinforced cellulose raw material can be secured.

In order to remove the non-cellulosic component, the kenaf fiber may be reacted with an alkali solution to obtain an alkali-treated kenaf fiber. By treating the kenaf fibers with alkali, non-cellulosic components contained in the kenaf fibers can be removed, thereby obtaining kenaf fibers with enhanced strength and durability. In addition, since the non-cellulosic component contained in the kenaf fiber is removed, the amorphous region through which moisture can penetrate increases, thereby improving the hygroscopicity of the kenaf.

In the case of alkali treatment, the type of the alkali solution is not particularly limited, but, for example, at least one selected from the group consisting of alkali sodium hydroxide (NaOH), potassium hydroxide (KOH) and calcium hydroxide (Ca(OH) ₂ ) is preferable.

In addition, the concentration of the alkali solution is preferably 1 to 50% by weight. If the concentration is less than 1% by weight, the removal efficiency of hemicellulose, lignin and sugar contained in the kenaf fiber decreases, and if it exceeds 50% by weight, the alkalinity is too high, and the non-cellulose as well as the cellulose-based fiber structure may be destroyed.

The mesh layer including the decorative layer is not limited in its pattern, and may have a pattern such as a rhombus (diamond type), a quadrangle or a honeycomb, among which the structure is preferably a rectangle or a honeycomb type. It is good to be able to secure the internal stability.

In addition, the laminated glass may further include a film layer of various colors in addition to the mesh layer or the adhesive layer as described above. In addition, when forming the adhesive layer, a dye or pigment such as blue or yellow may be further mixed with the adhesive layer composition to improve decorativeness and aesthetics, and to double the visual effect.

Next, as in step d), the connection frame 160 may be coupled to a portion where both ends of the side frame meet to shield a portion of the outer surface of the side frame. At this time, as long as the cross section has a 'C' shape opened in the direction in which the side frame is inserted, to explain this in more detail, as long as the connection part 161 and both ends of the connection part are extended and then bent to face them A pair of frame fixing units 162 may be included.

However, the connection frame may be provided at the part where both ends of the side frame meet, but in some cases, to increase the bonding force with the fixing object, it is also provided in a place where both ends of the side frame do not meet as in FIGS. 1 and 2 can be That is, the connection frame is basically located at the portion where both ends of the side frame meet, but when the size of the laminated glass is large and it is difficult to fix it with one connection frame, the coupling force is provided by having two or more of the same or different sizes. can increase

In addition, the connection frame may be provided on the side frame or the straight frame, but may be provided on the curved frame. In this case, the connection frame connects the curved frame and the fixing target, but the fixing target may be a floor rather than a wall.

As shown in FIG. 11, the connecting frame has a 'c' shape in a cross-section that is the same as a cross-section perpendicular to the longitudinal direction of the side frame, and the size or provided position is not limited. The connection part adjoins the side frame and the fixing means on both sides, respectively, and both ends of the side frame are turned to the outside by the frame fixing part formed by bending the portions extending at both ends of the connection part to face in and out of 90°. It is completely wrapped so as not to be exposed to protect the vulnerable part of the side frame and further increase durability, and at the same time, it is possible to minimize the fixed part with the fixing target through the connection frame, and it is economical because it can be installed quickly and effectively.

To this end, as shown in FIG. 11 , the connection frame may further include one or a plurality of through-holes 164 on the surface positioned in the insertion direction of the laminated glass.

The purpose of the through hole is different depending on the formation position thereof. When the through hole is formed in the frame fixing part, the frame fixing pin is inserted into the through hole as shown in FIG. 11 to fix the body part or the extension part of the side frame. In addition, when the through-hole is formed in the connection part, a protrusion formed on the fixing target of the laminated glass, other through-holes formed at the same height as the ground on the installation surface of the fixing target, and fixing means (bolts, etc.) passing through the through-holes ), the two objects (laminated glass and fixed object) are connected to each other. Through this, the laminated glass according to the present invention can greatly increase the assembling property.

The through-hole may have a screw thread (not shown) formed on the inner surface as needed. The screw thread is useful when the fixing means is in the form of a bolt, and as the fixing means is rotated and fixed with the screw thread, it is tightened to each other, and the screw thread of the fixing means and the thread of the through hole are more closely engaged and fixed It is possible to prevent the means from loosening or the fixing means from being damaged by the weight of the laminated glass.

The through-holes do not limit the formation position, number, diameter of the holes, and the like. For example, the through-holes are formed in a straight frame, and it is preferable to form a distance of 200 to 400 mm apart from the corners of the butt joint surface that directly contact the fixing target. In addition, the diameter of the through hole is preferably in the range of 1 to 20 mm, but is not limited thereto.

The present invention includes a laminated glass for bathroom manufactured as described above. The laminated glass is characterized in that the side is shielded with a reinforcing frame including a side frame to increase the mechanical properties and stability of the laminated glass and to reduce the risk of breakage.

In addition, by further providing a metal mesh layer and a decorative layer separate from the metal mesh layer inside, it is possible to impart aesthetics and opacity such as a pattern to the laminated glass, thereby protecting the privacy of the user.

The laminated glass according to the present invention does not limit the construction method. For example, the laminated glass that has been assembled until the frame can be installed by directly connecting it to the bathroom wall material, but it may be installed by first installing the unassembled laminated glass frame and then inserting the laminated glass here.

If the method of simultaneously proceeding with the installation and assembly as described above is described in more detail,

Forming a perforated portion for fastening the fixing (combination) means to the wall material or other fixing object of the bathroom to be constructed;

after matching the perforated portion with the through hole of the connecting frame, inserting the fixing means into the through hole and the perforated portion to fix the connecting frame to the fixing target;

inserting an adhesive and laminated glass into guide grooves of the side frame in order and curing the adhesive to completely bond the side frame and laminated glass; and

After inserting the frame fixing pin into the through hole formed in the frame fixing part among the through holes of the connection frame, inserting the side frame to which the laminated glass is coupled into the open portion of the connection frame, and then moving the frame fixing pin fixing the side frame to the connecting frame and completing the construction at the same time;

may include

That is, the laminated glass for bathroom according to the present invention can be constructed even before completion according to the construction method, and the laminated glass can be assembled at the same time as construction. Therefore, the finished laminated glass can be directly constructed and installed on the fixed object, but it is also possible to install the unassembled laminated glass frame first, and then insert the laminated glass thereto to be combined.

Therefore, in the case of directly constructing the finished laminated glass, it is difficult to install the perforated part and the through hole exactly in line with each other due to the weight of the laminated glass, and the fixing means is passed through the through hole with the fixing means inserted into the perforated part in advance. Therefore, it is difficult to perform a strong fixation, and it is almost impossible to provide a screw thread in the fastening means.

However, through the process as described above, the laminated glass for bathroom according to the present invention can be quickly and easily installed vertically to the fixed object by using a frame that helps the connection frame to be installed. That is, by first installing the connection frame on the fixing target and fixing it, the installation position of the connection frame can be accurately set, and the fixing means can further include additional fastening auxiliary means such as a screw thread, so that the bonding strength can be increased. there is. In addition, the construction of laminated glass for bathroom is completed only by inserting and coupling the side frame into the open groove of the connection frame in the state in which the connection frame is installed first as described above, can be easily carried out through

Although specific embodiments of the present invention have been described and illustrated as described above, the present invention is not limited to the described embodiments, and it is common in the art that various modifications and variations can be made without departing from the spirit and scope of the present invention. This is obvious to those with knowledge. Accordingly, such modifications or variations should not be individually understood from the technical spirit or point of view of the present invention, and the modified embodiments should belong to the claims of the present invention.
