Description

Technical Field

[0001] This application relates to the field of edge-sealed glass technology, and in particular to an edge-sealed glass assembly and its preparation method. Background Technology

[0002] With the increasing trend and fashionable design of new energy vehicles, people have higher and higher requirements for the overall styling of automobiles, including new demands on the appearance of the automotive window cladding assembly. People want the exterior color of the window cladding assembly to match the overall color of the car, especially the body paint color. For example, when the car's body paint is green, the cladding color of the window cladding assembly should also be green, ensuring a match between the two.

[0003] However, the currently produced edge-sealed glass assemblies are made of PVC (Polyvinyl Chloride) or TPE (Thermoplastic Elastomer) materials, which are injection molded to form a black edge on the glass. The color is monotonous and lacks distinctive features, failing to meet market demands.

[0004] In addition, the edge glass assembly on a vehicle is exposed to the natural environment for a long time, and the edge of the edge glass assembly may experience problems such as color change, loss of gloss, and aging. In order to ensure that the edge glass assembly can maintain a good appearance after long-term exposure to the natural environment, the edge needs to have good aging resistance.

[0028] The present invention also provides a method for preparing the above-mentioned edge-sealed glass assembly, the method comprising the following steps:

[0029] 1) Mixing: First, grind and stir 5-25 parts by weight of pigment, 5-15 parts by weight of lubricant and 5-15 parts by weight of filler for 15-30 minutes. Then add 40-100 parts by weight of resin, 0.2-1 parts by weight of stabilizer and 0-1.5 parts by weight of additives and stir and mix evenly. Then stir at 100-120℃ for 45-60 minutes. Finally, cool to room temperature while stirring to obtain the mixture.

[0030] 2) Granulation: The well-stirred mixture is granulated at a temperature of 160℃-220℃ to obtain granules;

[0031] 3) Melting and plasticizing: The granules are melted and plasticized into a viscous melt at 180℃-230℃.

[0032] 4) Injection: Set the injection pressure and holding pressure of the injection molding machine to inject the viscous melt into the mold cavity;

[0033] 5) Preparation of edge-sealed glass assembly: After the viscous melt is cooled and solidified in the cavity of the mold, the mold is opened to obtain the edge-sealed glass assembly.

[0034] In one possible implementation, the injection pressure range of the injection molding machine in step 4) is 0 to 120 bar, the holding pressure range is 0 to 30 bar, and the temperature of the mold is 10°C to 60°C.

[0035] The present invention, by adopting the above-described technical solution, has the following beneficial effects:

[0036] 1) The edge-sealing material used in the preparation of the edge-sealed glass assembly of the present invention comprises 57 to 85 parts of resin, 5 to 25 parts of pigment, 0.2 to 1 part of stabilizer, 5 to 15 parts of lubricant, 5 to 15 parts of filler, and 0 to 1.5 parts of additives. The edge-sealing material contains stabilizer, lubricant, and filler. The stabilizer can be used to improve the aging resistance and other properties of the edge-sealed glass assembly. The lubricant is used to reduce friction between the edge-sealed glass assemblies and to improve the lubricity of the edge-sealed glass assembly. The filler is used to improve the strength and other mechanical properties of the edge-sealed glass assembly, making the internal structure of the injection-molded edge very stable for long-term use.

[0037] 2) The pigments in the edging material of the present invention include red pigment, yellow pigment and blue pigment. The pigments are mixed according to the principle of three primary color mixing, that is, the three primary colors of red pigment, yellow pigment and blue pigment are mixed in different proportions to mix the colored edging required for the edging glass assembly product. The red pigment includes one or more of anthraquinone red PR.168, quinacridone red PR.122, dipyrrole (DPP) red PR.254, PR.255, and PR.264; the yellow pigment includes one or more of isoindolinone yellow PY.109, PY.110, and PY.139, benzimidazolone yellow PY.151, PY.154, PY.180, and PY.181, and quinoline yellow PY.138, PY.168, PY.183, and PY.191; and the blue pigment includes one or more of phthalocyanine blue PB15:4, phthalocyanine blue PB15:3, phthalocyanine blue PB15:1, and phthalocyanine blue PB15:0.

[0038] 3) In the preparation method of the edge-sealed glass assembly of the present invention, during the mixing of raw materials, the pigment is first mixed with lubricant and filler, and then resin, stabilizer and additives are added and mixed. Specifically, mixing the pigment with lubricant and filler first serves two purposes: firstly, the lubricant coats the pigment surface, isolating pigment particles and preventing them from agglomerating and increasing in size after heating; secondly, the filler acts as a grinding agent, and the friction between the filler and pigment refines the pigment particles. The present invention not only produces the desired appearance color of the edge-sealed glass assembly, but also ensures a more uniform appearance color.

[0039] 4) The preparation process of this invention is simple and easy to implement, which is conducive to industrial production. Attached Figure Description

Obviously, the drawings described below are only some embodiments of this application. For those skilled in the art, other drawings can be obtained based on these drawings without creative effort.

[0041] Figure 1 This is a schematic diagram of the edge-sealed glass assembly provided in this application embodiment applied to a vehicle.

[0042] Figure 2 for Figure 1 A schematic diagram of the edge-mounted glass assembly in the vehicle shown.

[0043] Figure 3 for Figure 1 Another structural schematic diagram of the edge-mounted glass assembly in the vehicle shown. Detailed Implementation

[0044] The technical solutions of the embodiments of this application will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of this application, and not all embodiments. Based on the embodiments of this application, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of this application.

[0045] Please see Figure 1 and Figure 2 , Figure 1 This is a schematic diagram of the edge-sealing glass assembly 1200 provided in this application embodiment applied to a vehicle 1000. Figure 2 for Figure 1 The diagram shows the structure of the edge-mounted glass assembly 1200 in vehicle 1000.

[0046] Vehicle 1000 includes a body 1100 and a side window assembly 1200. The side window assembly 1200 is mounted on the body 1100. The side window assembly 1200 can be a windshield assembly or a corner window assembly. This application embodiment uses a corner window assembly as an example.

[0047] The edge-sealed glass assembly 1200 includes a glass 100 and an edge 200, the edge 200 being installed on the edge of the glass 100. When the edge-sealed glass assembly 1200 is installed in a vehicle body, the edge 200 seals the gap between the glass 100 and the vehicle body. In this embodiment, the edge-sealed glass assembly 1200 has a single-color edge 200, and the glass 100 and the edge 200 are integrally injection molded.

[0048] The following details the formula of the edge-wrapping 200 in the edge-wrapping glass assembly 1200 and the preparation method of the edge-wrapping glass assembly 1200.

[0049] This embodiment also provides a edging glass assembly 1200, including glass 100 and edging 200 fixed on glass 100. The edging 200 includes the following raw materials in parts by weight: 40 to 100 parts of resin, 5 to 25 parts of pigment, 0.2 to 1 part of stabilizer, 5 to 15 parts of lubricant, 5 to 15 parts of filler and 0 to 1.5 parts of additives.

[0050] The edge-sealed glass assembly 1200 provided in this embodiment contains stabilizers, lubricants, and fillers in the material of the edge-sealing 200. The stabilizers can be used to improve the aging resistance and other properties of the edge-sealed glass assembly 1200. The lubricants are used to reduce friction between the edge-sealed glass assemblies 1200 and improve the lubricity of the edge-sealed glass assembly 1200. The fillers are used to improve the strength and other mechanical properties of the edge-sealed glass assembly 1200, making the internal structure of the injection-molded edge-sealing 200 very stable for long-term use.

[0051] In one possible implementation, the edge banding 200 comprises the following raw materials in parts by weight: 42 to 85 parts of resin, 5 to 25 parts of pigment, 0.2 to 1 part of stabilizer, 5 to 15 parts of lubricant, 5 to 15 parts of filler, and 0 to 1.5 parts of additives.

[0052] In one possible implementation, the edging 200 comprises the following raw materials in parts by weight: 57 to 85 parts by weight of resin, 5 to 25 parts by weight of pigment, 0.2 to 1 part by weight of stabilizer, 5 to 15 parts by weight of lubricant, 5 to 15 parts by weight of filler, and 0 to 1.5 parts by weight of additives.

[0053] In this embodiment, more preferably, the raw materials of the edging 200, by mass fraction, include 42.5% to 84.8% resin, 5% to 25% pigment, 0.2% to 1% stabilizer, 5% to 15% lubricant, 5% to 15% filler and 0% to 1.5% additives.

[0054] The resin includes one or more of polyvinyl chloride (PVC), styrene-butadiene block copolymer (SEBS), polypropylene (PP), and rubber. For example, the resin is polyvinyl chloride (PVC). For example, the resin is a mixture of SEBS and PP. Alternatively, the resin is a mixture of rubber and PP. For example, the rubber is ethylene propylene diene monomer (EPDM).

[0055] Based on their light transmittance, materials can be categorized as follows: Transparent materials: transmittance of visible light (400nm-800nm) above 80%; Semi-transparent materials: transmittance of visible light (400nm-800nm) between 50% and 80%; Opaque materials: refractive index of visible light (400nm-800nm) below 50%. According to this classification, resins are divided into transparent resins and non-transparent resins. Non-transparent resins include semi-transparent and opaque resins. For example, transparent resins can be PVC resin, a mixture of SEBS and PP, or a mixture of EPDM and PP. Non-transparent resins can be PVC resin, a mixture of SEBS and PP, or a mixture of EPDM and PP. It is important to understand that the transparency of a resin is related to its molecular weight and crystallinity. Since the same resin exhibits different transparency at different molecular weights, the same type of resin can be used for both transparent and non-transparent resins. Furthermore, crystallinity includes the degree of crystallinity and the size of the crystal particles. Higher degrees of crystallinity and larger crystal particle sizes make it less transparent.

[0056] Furthermore, the color of the edging compound 200 is also affected by other additives in its raw materials and the transparency of the resin itself. Therefore, the pigment ratio needs to be adjusted according to the actual appearance color required by the product. When the resin is transparent, the amount of pigment added does not need to be excessive. For example, if the content of transparent resin in the raw materials of the edging compound 200 is 57 to 85 parts by weight, the amount of pigment added is 5 to 10 parts by weight. When the resin is non-transparent, the amount of pigment added needs to be increased. For example, if the content of non-transparent resin in the raw materials of the edging compound 200 is 42 to 75 parts by weight, the amount of pigment added is 15 to 25 parts by weight.

[0057] In this embodiment, the pigments in the raw materials of the edging 200 include red, yellow, and blue pigments. The pigment mixing in this embodiment is based on the fundamental principle of tri-primary color mixing, that is, red, yellow, and blue pigments are mixed in different proportions to create the desired colored edging 200, thereby forming the colored edging glass assembly 1200 product.

[0058] It is important to understand that when the edge-mounted glass assembly 1200 is applied to the vehicle 1000, the vehicle 1000's requirements for the aging resistance of the edge-mounted glass assembly 1200 must also be considered, especially the aging resistance of the edge-mounted glass 200. Because the pigments in the raw materials of the edge-mounted glass 200 have a certain impact on its aging resistance, this application requires that the pigments in the raw materials of the edge-mounted glass 200 possess certain aging resistance properties. In this application, considering the requirements for pigment aging resistance, there are special requirements for pigment selection. Unlike other industries where different pigments can be added arbitrarily according to color requirements, this approach, while satisfying color requirements, ultimately fails to meet the vehicle's requirements for the aging resistance of the edge-mounted glass assembly.

[0059] According to the requirements for pigment aging resistance in the embodiments of this application, the red pigment, exemplarily, includes one or more of anthraquinone red PR.168, quinacridone red PR.122, dipyrrole (DPP) red PR.254, PR.255, and PR.264; the yellow pigment includes one or more of isoindolinone yellow PY.109, PY.110, and PY.139, benzimidazolone yellow PY.151, PY.154, PY.180, and PY.181, and quinoline yellow PY.138, PY.168, PY.183, and PY.191; the blue pigment can be phthalocyanine blue, specifically varieties such as PB15:4, PB15:3, PB15:1, and PB15:0. Preferably, PB15:3.

[0060] The aforementioned pigments not only possess certain aging resistance properties but also exhibit synergistic effects when combined with each other. Furthermore, they are beneficial for the preparation of the 1200 edge-sealed glass assembly.

[0061] When the edge-sealed glass assembly 1200 requires a dark-colored edge-sealing appearance (such as gray, black, etc.), since the resin, stabilizer, lubricant, filler, toughening agent, and flame retardant in the raw materials of the edge-sealing 200 may be opaque, it is necessary to add black pigment to neutralize the influence of the resin and / or other additives on the edge-sealing appearance color. In the embodiments of this application, the black pigment is preferably carbon black, more preferably carbon black PB7.

[0062] Meanwhile, considering the requirements of the 1200 edge-sealed glass assembly for color brightness and hue, and the vibrancy and diversity of the colors of the 1200 edge-sealed glass assembly, other colored pigments, such as quinacrine violet PV.19, permanent violet PV.23, orange PO.3, and DPP orange PO.73, can be added to the raw materials of the edge-sealed glass assembly 200.

[0063] Furthermore, the particle size of the pigment has a certain impact on the aging resistance of the edging 200. In this application, the pigment particle size is between 60 and 80 micrometers, which not only has better color strength and hiding power, but also fully utilizes the pigment's aging resistance in the edging. In some embodiments, the pigment particle size is between 65 and 70 micrometers.

[0064] In addition to the pigment itself needing to resist oxidation and aging such as ultraviolet light, this embodiment of the application adds a certain amount of stabilizer to the formulation of the edging 200 to further improve the aging resistance and other properties of the edging 200, thereby further improving the aging resistance and other properties of the edging glass assembly 1200. For example, the stabilizer includes one or more combinations of benzophenone compounds and benzotriazole compounds.

[0065] The lubricant serves two purposes: firstly, it coats the pigment surface, isolating pigment particles and preventing them from agglomerating and increasing in size after heating; secondly, it reduces friction between the raw materials of the edging 200 and improves the lubricity of the edging glass assembly 1200. For example, the lubricant may be one or a combination of butyl stearate, pentaerythritol stearate, paraffin wax, and dimethylsilane.

[0066] The filler is used to improve the strength and other mechanical properties of the 1200-inch edge-sealed glass assembly. For example, the filler may be one or a combination of ultrafine talc powder, mica powder, nano-calcium carbonate, wollastonite, etc.

[0067] The additives include toughening agents and flame retardants. For example, chlorinated polyethylene is selected as the toughening agent, and the toughening agent accounts for 0 to 0.5 parts by weight in the raw material of the 200mm edge banding. Tributyl phosphate is selected as the flame retardant, and the flame retardant accounts for 0 to 1 part by weight in the raw material of the 200mm edge banding.

[0068] This application embodiment also provides a method for preparing the above-mentioned edge-sealed glass assembly 1200, including the following steps:

[0069] 1) Mixing: First, put 5-25 parts by weight of pigment, 5-15 parts by weight of lubricant and 5-15 parts by weight of filler into a storage tank and grind and stir for 15-30 minutes. Then, put 40-100 parts by weight of resin, 0.2-1 parts by weight of stabilizer and 0-1.5 parts by weight of additives into the storage tank and stir and mix evenly. Then, stir at 100℃-120℃ for 45-60 minutes. Finally, cool to room temperature while stirring to obtain the mixture.

[0070] 2) Granulation: The well-mixed material is granulated using a twin-screw extruder at a temperature of 160℃-220℃ to obtain granules;

[0071] 3) Melting and plasticizing: Under conditions of 180℃-230℃, the granules are melted and plasticized into a viscous melt in the barrel of the injection molding machine;

[0072] 4) Injection: Set the injection pressure and holding pressure of the injection molding machine, and inject the viscous melt into the cavity of the mold containing the glass 100 and fill the cavity of the mold.

[0073] 5) Preparation of the edge-sealed glass assembly 1200: After the viscous melt cools and solidifies in the mold cavity, the mold is opened to obtain the edge-sealed glass assembly 1200. The viscous melt, after cooling and solidification, forms the edge 200.

[0074] In the process of mixing the above raw materials, considering the influence of pigment particle fineness on the aging resistance of the edge-sealing, in order to ensure that the pigment particle fineness meets the weather resistance requirements of the edge-sealing glass assembly product 1200, this application embodiment, in the process of preparing the edge-sealing glass assembly 1200, first mixes the pigment with lubricant and filler during the mixing of raw materials, and then adds resin, stabilizer, and additives for mixing. Specifically, mixing the pigment with lubricant and filler first allows the lubricant to coat the surface of the pigment, isolating the pigment particles and preventing them from agglomerating and increasing in size after heating. On the other hand, the filler has a certain grinding effect; the friction between the filler and pigment refines the pigment particles, thereby meeting the requirements of the plastic's aging resistance for pigment particle fineness. This invention not only produces the desired appearance color for the edge-sealing glass assembly 1200 product, but also ensures that the product has a relatively uniform appearance color.

[0075] In step 4), the molten material can be molded by injecting the viscous melt into a mold at a temperature of 10°C to 60°C under an injection pressure of 0–120 bar, and then holding and cooling it under a pressure of 0–30 bar. In some embodiments, the injection pressure is 70 bar to 110 bar. In some embodiments, the mold temperature is 25°C to 45°C. In some embodiments, the holding and cooling pressure is 10 bar to 25 bar.

[0076] The performance of the edge-sealed glass assembly 1200 is described below with reference to specific embodiments.

After 2500 hours of testing, the color difference value of the sample was ≥5 and the gloss loss rate was 25%-35%. The appearance color of the 200 edge-sealed glass assembly was gray, but it was impossible to achieve uniform color mixing, resulting in uneven stripes on the edge-sealed surface.

[0158] Examples 1, 2, 3, 4, Comparative Examples 1, 2, 3, 4, and 5 (Comparative Examples 1 and 5) simulated outdoor conditions such as ultraviolet radiation, high temperature, and high humidity in a xenon lamp aging test chamber to conduct accelerated aging tests on the edge-sealed glass assembly 1200 samples to evaluate their aging resistance. Specifically, xenon lamp aging tests were conducted on the edge-sealed glass assembly 1200 samples from Examples 1, 2, 3, 4, Comparative Examples 1, 2, 3, 4, and 5. The xenon lamp aging tests were performed according to the SAE J2527 standard, and the test conditions are shown in Table 1. After 2500 hours of xenon lamp aging testing, the surface gloss and color change of the edge-sealed glass assembly 1200 samples were measured using a gloss meter and a colorimeter. The gloss loss rate and color difference value of the samples after the xenon lamp aging test were recorded as evaluation criteria for aging resistance. The surface gloss and color change standards of the 1200 sample of the edging glass assembly after the xenon lamp aging test are shown in Table 2.

[0159] Table 1 Test conditions for xenon lamp aging test

[0160]

[0161] Table 2 Standards for Surface Gloss and Color Change Grades of Samples

[0162]

[0163]

[0164] As described above, after 2500 hours of xenon lamp aging test, the surface gloss and color difference of the edge-sealing glass assemblies 1200 samples in Examples 1, 2, 3, and 4 showed only slight changes (grade ≤ 1). However, the surface gloss of the edge-sealing glass assemblies 200 in Comparative Examples 3 and 5 was significantly diminished, and the surface gloss of the edge-sealing glass assemblies 200 in Comparative Examples 1, 2, and 4 was severely diminished. Furthermore, the color difference of Comparative Examples 1, 2, 3, 4, and 5 showed significant discoloration (grade ≥ 5). In the present application, by mixing pigments with lubricants and fillers during the preparation of the edge-sealing glass assembly 1200, the prepared edge-sealing glass assemblies 200 maintained good gloss after 2500 hours of xenon lamp aging test, exhibiting almost no color difference compared to the edge-sealing glass before the xenon lamp aging experiment, demonstrating good aging resistance. Experimental results show that in the process of preparing the edge-sealed glass assembly 1200 in this embodiment, mixing the pigment with lubricant and filler first allows the pigment particles to be refined through mutual friction between the filler and pigment, forming pigment particles with a fineness of 65 to 70 micrometers, thereby improving the aging resistance of the edge-sealing 200. Simultaneously, mixing the lubricant with the pigment first allows the lubricant to coat the surface of the pigment, isolating the pigment particles and preventing them from agglomerating and increasing in size after heating, thus further improving the aging resistance of the edge-sealing 200.

[0165] This application has been verified through extensive experiments. By mass fraction, when the resin content in the raw materials of the edge-wrapping 200 is controlled at 42%–84.8%, the pigment content at 5%–25%, the stabilizer content at 0.2%–1%, the lubricant content at 5%–15%, the filler content at 5%–15%, and the additive content at 0%–1.5%, the resulting edge-wrapping glass assembly still maintains good gloss after 2500 hours of xenon lamp aging test. The color of the edge-wrapping glass assembly before the xenon lamp aging test is almost the same, indicating good aging resistance. This meets the aging resistance requirements of the edge-wrapping glass assembly 1200 in Vehicle 1000.

[0166] Specifically, when a transparent resin is used in the raw materials of the edging compound 200, the raw materials of the edging compound 200 may include, by mass fraction, 57.5% to 84.8% transparent resin, 5% to 10% pigment, 0.2% to 1% stabilizer, 5% to 15% lubricant, 5% to 15% filler, and 0% to 1.5% additives. When a non-transparent resin is used in the raw materials of the edging compound 200, the raw materials of the edging compound 200 may include, by mass fraction, 42.5% to 74.8% non-transparent resin, 15% to 25% pigment, 0.2% to 1% stabilizer, 5% to 15% lubricant, 5% to 15% filler, and 0% to 1.5% additives. The aforementioned edge glass assembly 1200 maintained good gloss after undergoing a 2500-hour xenon lamp aging test. Compared to the color of the edge glass assembly 1200 before the xenon lamp aging test, there was almost no color difference, indicating good aging resistance. This meets the requirements of Vehicle 1000 for the aging resistance of the edge glass assembly 1200.

[0167] In this application embodiment, the color of the edge-sealing glass assembly 1200 is based on the principle of three primary color tones. At the same time, the selection and addition amount of pigments are adjusted according to whether the resin in the edge-sealing material 200 is transparent or non-transparent, so as to prepare the edge-sealing glass assembly 1200 with the target color, which in turn facilitates the preparation of plastic parts with the target color.

[0168] It is understood that in other embodiments, the edging 200 includes a first edging 210 and a second edging 230 fixed to the glass 100, wherein the first edging 210 and the second edging 230 are integrally formed by two-material injection molding, such as... Figure 3 As shown. The color of the first edging 210 is different from the color of the second edging 230. For example, the first edging 210 is black, and the second edging 230 is green. Specifically, a two-material injection mold and equipment can be used. First, black material for the first edging 210 is injected to form the first edging 210. Then, the glass product with the first edging 210 is placed into another mold, and green material for the second edging 230 is injected, resulting in a colored edging 200 with a combination of black and green colors.
