Abstract
Description
Technical Field
[0001] The utility model belongs to the technical field of edge sealing of insulating glass for building doors and windows, and particularly relates to a composite warm-edge rigid spacer for insulating glass. Background Art
[0002] The rigid spacers used in existing insulating glass are mainly metal spacers and polymer composite spacers. When the existing rigid spacers are bent to form a frame, the bending stress of the spacers will cause problems such as bending springback of the spacers, squeezing of the corners of the spacer frame, and outward expansion of the bent corners of the spacer frame, which affect the frame forming of the spacers.
[0003] (1) Due to different stretching degrees of the upper and lower surfaces at the bent corner of the spacer frame, under the action of stress springback, presetting an excessive bending angle will also cause the shape of the spacer frame not to meet the standard, and even the joint of the spacer frame may be stretched and broken.
[0004] (2) Under the action of stress, the two vertical sides at the bent corner of the spacer frame will expand outward. This swelling angle at the bent part of the spacer will affect the quality of insulating glass lamination, and even cause glass breakage during lamination.
[0005] (3) Under the combined stress of different stretching degrees of the upper and lower surfaces and the extrusion expansion of the vertical sides at the bent corner of the spacer frame, the spacer at the bent part will be too flat, affecting the coating of the edge sealant and resulting in sealing failure.
[0006] (4) The sealant coated on the edge of the bent frame often shows uneven calendering during pressing, and even flows into the interior of the insulating glass, affecting the aesthetics of the edge of the insulating glass. Content of the Utility Model
[0007] In order to solve the above problems and overcome the problems of springback, swelling angle, flattening, and flowing sealant at the bent corners of the existing composite warm-edge rigid spacers for insulating glass, a composite warm-edge rigid spacer for insulating glass is provided.
[0008] To achieve the above object, the technical solution adopted by the utility model is as follows: a hollow glass composite warm-edge rigid spacer, which includes a polymer material spacer body with a hollow cavity inside. The polymer material spacer body includes an upper end face, a lower end face and two vertical edges. The left and right sides between the upper end face and the lower end face are respectively connected to one vertical edge. The two vertical edges are bent towards the inside of the hollow cavity, and a concave portion is provided on the outer side surface of each vertical edge along the length direction. Inside the joint of the upper end face and the upper ends of the two vertical edges, metal wires are respectively provided along the length direction. At the lower ends of the left and right sides of the upper end face, upper protruding structures are respectively provided downward. The left and right sides of the lower end face are respectively inclined obliquely upward to form inclined surfaces, and lower protruding structures are respectively provided upward along the ends of the inclined surfaces. The upper protruding structures and the lower protruding structures on the same side are both located outside the concave portion on the same side, and the outer end face of the upper protruding structure protrudes outward more than the outer end face of the lower protruding structure;
[0009] On the upper surface of the upper end face, two grooves are provided along the length direction, and a plurality of vent holes are provided at intervals in each groove. A support column extends upward from the upper surface of the lower end face or downward from the lower surface of the upper end face.
[0010] Further, the polymer material spacer body is made of one of epoxy resin, polypropylene, polyethylene terephthalate, glass fiber modified epoxy resin, glass fiber modified polypropylene or glass fiber modified polyethylene terephthalate.
[0011] Further, the metal wire is made of steel or aluminum alloy, and the cross-section of the metal wire is rectangular or "I" shaped or "H" shaped.
[0012] Further, the cross-sectional shape of the concave portion is arc-shaped or wedge-shaped, and the concave portion is symmetrically structured up and down along the transverse center line AB of the vertical edge.
[0013] Further, the distance L by which the outer end face of the upper protruding structure protrudes outward more than the outer end face of the lower protruding structure is 0.2 mm to 0.5 mm.
[0014] Further, the cross-section of the support column is rectangular, and the height of the support column is less than the height of the hollow cavity inside the polymer material spacer body.
[0015] Further, a water vapor isolation protection layer is provided on the outer surface of the part below the transverse center line AB of the vertical edge, the outer surface of the lower protruding structure, the outer surface of the inclined surface and the outer surface of the lower end face.
[0016] Further, the water vapor isolation protection layer is a modified silicone coating or an aluminum-plastic film.
[0017] Further, sealant is coated in the recessed portion. The sealant fills the recessed portion and protrudes outward beyond the upper protruding structure and the lower protruding structure, forming a convex portion with an arc-shaped cross section.
[0018] Further, sealant is coated in the recessed portion. The sealant fills the recessed portion and protrudes outward beyond the upper protruding structure and the lower protruding structure, forming a convex portion with an arc-shaped cross section. Meanwhile, sealant is coated on the outer surface of the lower protruding structure, the outer surface of the inclined surface, and the outer surface of the lower end surface.
[0019] Compared with the prior art, the utility model has the following beneficial effects:
[0020] First, the utility model uses a polymer material spacer body and a metal wire to jointly form a composite rigid spacer. While the metal wire enhances the rigidity of the spacer, it reduces the springback at the bent corners of the spacer, and can reduce the heat conduction at the edge of the insulating glass while enhancing the physical and chemical properties of the spacer.
[0021] Second, there are inwardly concave vertical edges on both sides of the polymer material spacer body. When bending to form a frame, the stress is released into the spacer, preventing the expansion of the corners from affecting the later processing of the insulating glass.
[0022] Third, support columns are arranged inside the hollow cavity of the polymer material spacer body, so that the thickness of the spacer at the bent part meets the requirements, ensuring the sealing performance of the insulating glass.
[0023] Fourth, the polymer material spacer body can be pre-coated with sealant, reducing the later processing steps of the insulating glass, improving the production efficiency, and reducing the energy consumption. The outer end surface of the upper protruding structure on the outer side of the recessed portion of the vertical edge protrudes more outward than the outer end surface of the lower protruding structure, and a protruding structure for restricting the flow of the sealant can be formed, preventing the sealant coated in the groove from overflowing into the insulating glass, which affects the aesthetics of the edge of the insulating glass.
[0024] Fifth, a moisture isolation and protection layer is provided on the polymer material spacer body, which can enhance the adhesion to the coated sealant while preventing the infiltration of moisture.
[0025] In summary, the composite warm-edge rigid spacer for insulating glass of the utility model can solve the problems of springback at the bent corners of the spacer, expansion of the corners, flattening, and flowing sealant, and can reduce the production links, lower the energy consumption, and improve the aesthetics of the edge of the insulating glass.
