Description

Technical Field

[0001] This invention belongs to the field of glass manufacturing. Background Technology

[0002] The edge sealing performance of insulated glass directly determines its service life and heat insulation effect. Currently, the mainstream structure adopts a double sealing structure, specifically a first layer of butyl hot melt sealant and a second layer of polysulfide sealant or silicone structural sealant.

[0003] In production, two glass panes are typically joined together using a spacer and butyl rubber. Structural sealant is then injected manually or mechanically into a filling groove formed on the outside of the spacer. The sealant surface is then smoothed with a scraper until it is flush with the glass edge. After the sealant has cured, a protective tape or film is applied separately. This traditional process requires highly skilled operators for smoothing the sealant surface, which can easily result in depressions, ripples, or uneven thickness, affecting sealing and appearance. Furthermore, the structural sealant is exposed to air for extended periods, subjecting it to long-term UV radiation and moisture erosion. Summary of the Invention

[0004] Purpose of the invention: In order to overcome the shortcomings of the existing technology, the present invention provides an insulating glass and its manufacturing process, which isolates the structural adhesive from external ultraviolet rays, moisture and corrosive media, thereby extending the life of the sealing system.

[0005] Technical solution: To achieve the above objectives, the present invention provides an insulating glass unit comprising a parallel inner glass sheet, an outer glass sheet, and a spacer frame; the spacer frame is sandwiched between the inner and outer glass sheets at their edges, and the area enclosed by the spacer frame is a hollow layer filled with inert gas;

[0006] The inner and outer surfaces of the glass inner sheet and the glass outer sheet are sealed and bonded to each other along the contour surface by a sealant layer on both sides of the spacer frame. The outer contour of the spacer frame forms a consistent indentation relative to the outer contour of the glass inner sheet / glass outer sheet, thereby forming a frame-shaped filling groove outside the spacer frame. The frame-shaped filling groove is uniformly filled with structural sealant, forming a frame-shaped structural adhesive layer.

[0007] Furthermore, the cavities within the spacer frame are filled with molecular sieve desiccant.

[0008] Furthermore, the inner side of the outer glass sheet has a LOW-E film.

[0009] A manufacturing process for insulating glass includes the following steps:

[0010] Step 1: Trim the edges of the inner glass sheet and the outer glass sheet, clean the surface, and dry them in sequence;

[0011] Step 2: The aluminum spacer is formed into a rectangular spacer frame that matches the size of the glass. Then, molecular sieve desiccant is filled into the cavity of the spacer frame. Butyl adhesive is then continuously applied to the two glass bonding surfaces of the spacer frame to form a sealing adhesive layer on both sides of the spacer frame.

[0012] Step 3: Position the spacer frame on the inner surface of the inner glass sheet, ensuring uniform spacing around the edges. Then cover the outer glass sheet and align the four sides. At this point, a frame-like filling groove is formed around the spacer frame. The glass is then fed into a roller press for pressing, allowing the butyl rubber to adhere tightly to the two glass sheets under pressure, forming a semi-finished insulated glass assembly with a closed hollow layer.

[0013] Step 4: Inject structural sealant along the contour path into the frame-shaped filling groove around the edge of the insulated glass semi-finished component to form a frame-shaped structural sealant layer.

[0014] Step 5: Allow the glass to stand and cure under preset environmental conditions to obtain the finished two-piece slotted aluminum insulated glass.

[0015] Furthermore, in step two, the butyl rubber is preheated and melted to 130~140℃ before coating, and the coating pressure is controlled at 0.6~0.8MPa; the coated butyl rubber is continuous without breaks or bubbles, and the corners of the spacer frame, splicing interfaces and molecular sieve filling holes are treated with glue to ensure dense filling.

[0016] In step three, the pressing pressure of the roller pressing equipment after the two glass sheets are joined is 0.2~0.3MPa. After pressing, the butyl rubber is evenly extruded along the entire circle of the spacer frame without any gaps or breaks. During the joining process, inert gas is injected into the hollow cavity through the pre-set air inlet on the spacer frame. The concentration of inert gas in the cavity is ≥85%. After the air inlet is completed, the air inlet is sealed.

[0017] Furthermore, the outer ring surfaces of the inner glass sheet and the outer glass sheet are respectively the circumferential contour surface of the inner glass outer ring and the circumferential contour surface of the outer glass outer ring; the outer ring of the frame-shaped structural adhesive layer is wrapped with a wrapping tape, and the two sides of the contour edge of the wrapping tape are bonded to the circumferential contour surface of the inner glass outer ring and the circumferential contour surface of the outer glass outer ring by pressure-sensitive adhesive.

[0018] The specific process for step four is as follows:

[0019] S1, glass robotic arm, glue injection unit, and rolling roller; the glass robotic arm can hold the geometric center of the insulated glass semi-finished component. The vertical and horizontal directions of the plane where the insulated glass semi-finished component is located are denoted as the x-direction and y-direction, respectively. The axis perpendicular to the geometric center of the insulated glass semi-finished component is denoted as the z-axis; the glass robotic arm can drive the insulated glass semi-finished component to move in the xy plane, and the glass robotic arm can also drive the insulated glass semi-finished component to rotate around the z-axis.

[0020] S2. The glass robotic arm drives the semi-finished insulating glass assembly to rotate around the z-axis until any one of the apex corners of the semi-finished insulating glass assembly is vertically downward. The adhesive side of the pressure-sensitive sealing tape led out from the tape storage roller is taut and crosses the rolling roller. A section of the end of the led-out pressure-sensitive sealing tape adheres to the lower contour surface of the vertically downward apex corner of the semi-finished insulating glass assembly along a right-angle contour, forming a right-angled V-shaped initial wrapping section. At this time, the adhesive side of the right-angled V-shaped initial wrapping section seals and adheres to the inner glass outer ring circumferential contour surface and the outer glass outer ring circumferential contour surface at the vertically downward apex corner of the semi-finished insulating glass assembly. The rolling roller presses the connection between the right-angled V-shaped initial wrapping section and the led-out pressure-sensitive sealing tape tightly and with constant pressure on the outer circumferential surface of the semi-finished insulating glass assembly. At this time, an initial right-angled V-shaped injection cavity is formed on the upper side of the right-angled V-shaped initial wrapping section. At the same time, the dispensing end of the injection unit extends into one end of the injection cavity in the initial state.

[0021] S3. The dispensing end of the dispensing unit injects structural sealant into the dispensing cavity in the initial state, thereby filling the dispensing cavity in the initial state with structural sealant and forming a structural sealant filler adapted to the dispensing cavity.

[0022] S4. Under the action of the glass robotic arm, by controlling the movement of the insulated glass semi-finished component in the xy plane and rotating around the z-axis, the fixed-position rolling roller performs a rolling action along the outer contour of the insulated glass semi-finished component clockwise. This causes the pressure-sensitive sealing tape to gradually roll along the path onto the outer circumference of the insulated glass semi-finished component, thereby causing the injection cavity to gradually extend and lengthen along the clockwise path of the frame-shaped filling groove. At the same time, as the injection cavity gradually extends and lengthens along the clockwise path of the frame-shaped filling groove, the dispensing end of the injection unit continuously and adaptively injects structural sealant into the extension end of the injection cavity. This allows the structural sealant filler to be sealed and constrained by the pressure-sensitive sealing tape in real time as the extension path of the injection cavity gradually lengthens. When the rolling roller has rolled a complete circle along the outer contour of the insulated glass semi-finished component clockwise, the entire frame-shaped filling groove is uniformly filled with structural sealant, forming a frame-shaped structural sealant layer.

[0023] Beneficial effects: The wrapping tape of the present invention has a dual function. During the manufacturing process, it serves as an external constraint mold for adhesive injection, allowing the structural sealant to be filled and molded within the closed cavity, naturally forming a full and dense adhesive layer flush with the glass edge. During the service life of the finished product, it serves as a permanent protective layer, completely isolating the structural sealant from external ultraviolet rays, moisture, and corrosive media, thus extending the life of the sealing system.

[0024] In terms of process, wrapping and sealant injection are integrated into a single step. A glass robotic arm controls the semi-finished insulating glass unit so that one corner faces downwards. Pressure-sensitive sealing tape, drawn from a rolling roller, is applied at this corner to form a right-angled V-shaped initial wrapping section, creating an initial sealant injection cavity with its opening facing upwards. Subsequently, under the coordinated translation and rotation of the glass driven by the robotic arm, a fixed rolling roller rolls clockwise relative to the outer contour of the glass, causing the tape to continuously wrap and extend outwards into the sealant injection cavity. Meanwhile, the dispensing end of the sealant injection unit injects a measured amount of structural sealant into the continuously extending cavity. Throughout the process, motion control ensures that the extended end of the sealant injection cavity remains in an upward or slightly angled spatial posture, utilizing the sealant's own weight and injection pressure to achieve leak-free filling. When the rolling roller completes a full circle, the structural sealant precisely fills the entire frame-shaped filling groove and is sealed and constrained by the tape, achieving simultaneous wrapping and injection in one step. This eliminates the separate smoothing, trimming, and protective film application processes required in traditional methods. Attached Figure Description

[0031] The invention will now be further described with reference to the accompanying drawings.

[0032] like Figures 1 to 6 The hollow glass shown includes parallel inner glass sheet 1a, outer glass sheet 1b, and spacer frame 5; the spacer frame 5 is sandwiched between the inner glass sheet 1a and the outer glass sheet 1b, and the area enclosed by the spacer frame 5 is a hollow layer 2 filled with inert gas; the inert gas filled inside the hollow layer 2 is argon, and the thermal conductivity of argon is only 0.016 W / (m·K), which is much lower than that of air, and can effectively suppress convective heat transfer and conductive heat transfer in the hollow layer.

[0033] The inner side of the outer glass pane 1b is a LOW-E film. The LOW-E film is an offline silver-based low-emissivity film that can efficiently reflect far-infrared heat radiation from the indoor side back, reduce the loss of indoor heat to the outside in winter, and block outdoor heat from entering in summer, significantly reducing the heat transfer coefficient U value of the insulating glass. At the same time, the LOW-E film is set on both sides of the insulating layer 2 to avoid direct corrosion from the external environment and ensure the long-term stability of the film layer.

[0034] The inner surfaces of the inner glass sheet 1a and the outer glass sheet 1b are sealed along the contour surface by the sealant layer 5 on both sides of the spacer frame 5; the cavity inside the spacer frame 5 is filled with molecular sieve desiccant; the sealant layer 5 is made of butyl hot melt sealant, which has extremely low moisture permeability and can prevent external moisture from penetrating into the insulating layer 2 during long-term service of the insulating glass; the molecular sieve desiccant is a type 3A molecular sieve with an effective pore size of about 0.3 nm, which can preferentially adsorb infiltrated residual water molecules and volatile organic components without adsorbing inert gas molecules.

[0035] The outer contour of the spacer frame 5 is recessed in a consistent manner relative to the outer contour of the inner glass pane 1a / outer glass pane 1b, thus forming a frame-shaped filling groove 10 around the spacer frame 5. This recess is typically 8mm. The resulting frame-shaped filling groove 10 provides a defined filling cavity for the structural sealant, ensuring uniform sealant thickness and sufficient bonding area, thereby guaranteeing subsequent structural strength and sealing continuity. The frame-shaped filling groove 10 is uniformly filled with structural sealant, forming a frame-shaped structural sealant layer 6. This frame-shaped structural sealant layer 6 bonds the two glass panes and the spacer frame 5 into a unified load-bearing unit, bearing wind loads, self-weight, and shear stress caused by temperature deformation. It is the core force-transmitting layer ensuring the structural safety of the insulated glass unit.

[0036] The outer surfaces of the inner glass sheet 1a and the outer glass sheet 1b are the circumferential profile surface 8a of the inner glass outer ring and the circumferential profile surface 8b of the outer glass outer ring, respectively.

[0037] A manufacturing process for insulating glass includes the following steps:

[0038] Step 1: Trim the cut edges of the inner glass sheet 1a and the outer glass sheet 1b, then clean and remove impurities from the glass surface and dry them. The cut edges of the glass often have micro-cracks and residual stress. Trimming can eliminate stress concentration sources, significantly reduce the risk of spontaneous breakage during subsequent tempering or use, and at the same time ensure the cleanliness and adhesion of the subsequent sealant bonding interface.

[0039] Step two: The aluminum spacer is formed into a rectangular spacer frame 5 that matches the size of the glass. Then, molecular sieve desiccant is filled into the cavity of the spacer frame 5. Butyl adhesive is then continuously applied to the two glass bonding surfaces of the spacer frame 5, thereby forming a sealing layer 5 on both sides of the spacer frame 5. The aluminum spacer is made of thin-walled aluminum alloy profile, which is formed by bending or interlocking, and has good dimensional stability and corrosion resistance. The filling rate of the molecular sieve desiccant is not less than 70% of the cavity volume of the spacer frame to ensure that there is a sufficient amount of desiccant to maintain the dryness of the hollow layer for a long time.

[0040] Step 3: Position the spacer frame 5 on the inner surface of the inner glass sheet 1a, making the perimeter spacing uniform. Then cover the outer glass sheet 1b and align the four sides. At this time, a frame-shaped filling groove 10 is formed around the spacer frame 5. Then, it is sent into the roller pressing equipment for pressing, so that the butyl rubber is tightly bonded to the two glass sheets after being pressed, forming a semi-finished insulated glass component 7a with a closed hollow layer 2.

[0041] Step 4: Inject structural sealant along the contour path into a frame-shaped filling groove 10 around the edge of the insulated glass semi-finished component 7a, and form a frame-shaped structural sealant layer 6.

[0042] Step 5: Allow the glass to stand and solidify under preset environmental conditions to obtain the finished two-piece slotted aluminum insulated glass product 7.

[0043] In step one, the edge trimming process specifically involves grinding and chamfering the cut edges of the glass to remove sharp edges and micro-cracks. The chamfer angle is 45°, and the chamfer size is 0.5~1mm. Cleaning is performed by sequentially brushing and spraying with deionized water, followed by air drying.

[0044] In step two, the butyl rubber is preheated and melted to 130~140℃ before coating, and the coating pressure is controlled at 0.6~0.8MPa. The coated butyl rubber is continuous without any breaks or bubbles. The corners of the spacer frame, the splicing interfaces and the molecular sieve filling holes are treated with glue to ensure that the filling is dense.

[0045] In step three, the pressing pressure of the roller pressing equipment after the two glass sheets are joined is 0.2~0.3MPa. After pressing, the butyl rubber is evenly extruded along the whole circle of the spacer frame without any gaps or breaks. During the joining process, inert gas is injected into the hollow cavity through the pre-set air inlet on the spacer frame. The concentration of inert gas in the cavity is ≥85%. After the air inlet is completed, the air inlet is sealed.

[0046] The structural sealant used in step four is a two-component polysulfide sealant or a two-component silicone structural sealant, with the sealant surface flush with the glass edge.

[0047] In the optimized structure, a wrapping tape 13a surrounds the outer ring of the frame-shaped structural adhesive layer 6. The two contour edges of the wrapping tape 13a are bonded to the inner glass outer ring circumferential contour surface 8a and the outer glass outer ring circumferential contour surface 8b respectively using pressure-sensitive adhesive. The central portion of the wrapping tape 13a adhering to the frame-shaped structural adhesive layer 6 has an easily peelable release coating. In practice, the wrapping tape 13a can be removed before window installation or left on.

[0048] The wrapping tape 13a is a composite tape with PET film as the base material and weather-resistant acrylic pressure-sensitive adhesive coated on one side. The peel strength of the pressure-sensitive adhesive is ≥10N / 25mm, and the peel strength retention rate is greater than 80% after 1000h of ultraviolet aging. This wrapping tape serves as an external constraint layer before the structural sealant cures, ensuring that the surface of the adhesive layer is flat and flush with the edge of the glass. It also plays a protective role before curing. Under conditions such as handling vibration and accidental contact, the uncured frame-shaped structural adhesive layer 6 will not be affected. After curing, it will protect the structural sealant from direct corrosion by ultraviolet rays and moisture for a long time and give the glass edge a clean and beautiful appearance.

[0049] The optimized process for "Step Four" is as follows:

[0050] S1. Prepare a glass robotic arm, an adhesive injection unit 12, and a rolling roller 16. The glass robotic arm can hold the geometric center of the insulated glass semi-finished component 7a. The vertical and horizontal directions of the plane where the insulated glass semi-finished component 7a is located are denoted as the x-direction and y-direction, respectively. The axis perpendicularly passing through the geometric center of the insulated glass semi-finished component 7a is denoted as the z-axis. The glass robotic arm can drive the insulated glass semi-finished component 7a to move in the xy-plane, and the glass robotic arm can also drive the insulated glass semi-finished component 7a to rotate around the z-axis.

[0051] S2. The glass robotic arm drives the semi-finished insulating glass component 7a to rotate around the z-axis until any one of the apex corners of the semi-finished insulating glass component 7a is vertically downward, such as... Figure 4As shown, the adhesive side of the pressure-sensitive encapsulating tape 13 drawn from the tape storage roller is taut and passes over the rolling roller 16. A section of the end of the drawn pressure-sensitive encapsulating tape 13 is bonded along a right-angle contour to the lower contour surface of the vertically downward-facing corner of the insulated glass semi-finished assembly 7a, forming a right-angled V-shaped initial wrapping section 13aa. At this time, the adhesive side of the right-angled V-shaped initial wrapping section 13aa is sealed and bonded to the inner glass outer surface at the vertically downward-facing corner of the insulated glass semi-finished assembly 7a. The outer circumferential contour surface 8a and the outer circumferential contour surface 8b of the outer glass ring; the rolling roller 16 tightly and constantly rolls the connection between the right-angled V-shaped initial wrapping section 13aa and the pressure-sensitive encapsulating tape 13 onto the outer circumferential surface of the insulated glass semi-finished component 7a; at this time, an initial right-angled V-shaped injection cavity 10a is formed on the upper side of the right-angled V-shaped initial wrapping section 13aa, and at the same time, the glue outlet end of the glue injection unit 12 extends into one end of the initial injection cavity 10a; as Figure 4 As shown.

[0052] S3. The dispensing end of the injection unit 12 injects structural sealant into the injection cavity 10a in the initial state, thereby filling the injection cavity 10a in the initial state with structural sealant and forming a structural sealant filler 6a adapted to the injection cavity 10a, such as... Figure 5 As shown.

[0053] S4. Under the action of the glass robotic arm, by controlling the movement of the hollow glass semi-finished component 7a in the xy plane and its rotation around the z-axis, the fixed-position rolling roller 16 performs a rolling action along the outer contour of the hollow glass semi-finished component 7a clockwise. This causes the pressure-sensitive encapsulating tape 13 to gradually roll along the path onto the outer circumference of the hollow glass semi-finished component 7a, thereby causing the injection cavity 10a to gradually extend and lengthen along the clockwise path of the frame-shaped filling groove 10. During this step, through the control of the glass robotic arm, the extended end of the injection cavity 10a is always in an oblique or upward state to avoid glue leakage during the injection process. At the same time, as the injection cavity 10a gradually extends and lengthens along the clockwise path of the frame-shaped filling groove 10, the glue outlet of the injection unit 12 continuously... Structural sealant is injected into the extension end of the injection cavity 10a in an adaptive manner, so that the structural sealant filler 6a is sealed and constrained by the pressure-sensitive encapsulation tape 13 in real time as it gradually lengthens along the extension path of the injection cavity 10a; when the rolling roller 16 rolls a complete circle clockwise along the outer contour of the insulated glass semi-finished component 7a, the entire frame-shaped filling groove 10 is uniformly filled with structural sealant, forming a frame-shaped structural sealant layer 6. At the same time, the outer ring of the frame-shaped structural sealant layer 6 is simultaneously wrapped with a wrapping tape 13a. The two contour edges of the wrapping tape 13a are bonded to the inner glass outer ring circumferential contour surface 8a and the outer glass outer ring circumferential contour surface 8b respectively by pressure-sensitive adhesive; finally, the root of the wrapping tape 13a is cut off, and at this time, the two-piece slotted aluminum profile insulated glass finished product 7 is obtained; Figure 6 This step achieves the process characteristics of simultaneous packaging and injection, and one-step forming: the pressure-sensitive encapsulating tape instantly establishes a closed injection cavity during the continuous wrapping process of the rolling roller, and the structural sealant is simultaneously filled and constrained and shaped by the outer wall of the tape during the extension of the cavity, eliminating the independent processes of first injecting glue and then scraping, trimming and pasting protective film in the traditional process; the spatial posture control of the extension end of the injection cavity 10a always facing upward, using the combined action of the glue's own weight and injection pressure, makes the glue liquid fill smoothly and automatically compact, and finally forms a frame-shaped structural adhesive layer 6 with a surface flush with the glass edge and a precise shape.

[0054] S5. The residual pressure-sensitive sealing tape 13 on the tape storage roller is retracted first. Under the action of the glass robotic arm, the movement of the two-piece slotted aluminum insulated glass product 7 in the xy plane displacement and rotation around the z axis is controlled to make the fixed-position rolling roller 16 continue to perform a clockwise rolling action along the outer contour of the two-piece slotted aluminum insulated glass product 7. This results in the formed wrapping tape 13a being more tightly bonded to the outer circumferential surface of the outer contour of the two-piece slotted aluminum insulated glass product 7. This re-pressing and rolling process effectively eliminates any micro-bubbles and uneven bonding areas that may remain between the wrapping tape and the circumferential contour surface of the glass, further improving the peel strength and sealing protection effect of the wrapping tape, ensuring that it does not curl or fall off during subsequent transportation, installation and long-term service.

[0055] The above description is only a preferred embodiment of the present invention. It should be noted that for those skilled in the art, several improvements and modifications can be made without departing from the principle of the present invention, and these improvements and modifications should also be considered within the scope of protection of the present invention.
