Description

Technical Field

[0001] This invention relates to the field of architectural decorative glass materials and deep processing technology, specifically to a glass-ceramic composite glass that is tempered and simultaneously painted, multifunctional integrated tempered glass-ceramic glass, and its preparation process. Background Technology

[0002] Architectural decorative glass, stained glass, and ceramic decorative panels are currently the mainstream decorative materials for interior and exterior curtain walls, feature walls, and door and window partitions. Existing conventional products are mainly divided into categories such as ceramic tiles, ordinary tempered glass, post-painted art glass, mosaic finishes, and untempered ceramic art glass.

[0003] Currently, the industry standard process is to temper the glass first and then apply the colored paint. The colored paint layer is mostly applied using low-temperature inks and paints, which has problems such as poor adhesion, easy fading and aging, poor weather resistance, and insufficient safety. Glass and ceramic materials cannot be fused together at high temperatures simultaneously, and there are currently no glass-ceramic integrated composite tempered decorative glass products.

[0004] Traditional tempered glass lacks diverse optical decorative functions, and single-color stained glass lacks functions such as heat insulation, polarization and diffusion, light softening and emulsification, and anti-glare. The step-by-step processing technology is complicated, energy-intensive, and has a low yield rate, which limits mass production. It is difficult to simultaneously achieve high safety, long-lasting aesthetics, multi-functional decoration, and energy-saving and environmental protection characteristics, and cannot meet the diversified, high-quality, and long-lifespan requirements of high-end architectural decoration. Summary of the Invention

[0005] (a) Purpose of the invention This invention aims to provide an integrated tempered glass with stained glass and ceramic material and its preparation method. By using a high-temperature bonding layer structure of glass micropowder with a matching coefficient of expansion, combined with high-temperature inorganic ceramic ink and special functional optical materials, the pattern painting and curing, ceramic layer fusion and adhesion, and multi-functional layer shaping are completed simultaneously during the glass tempering process, realizing the high-temperature integrated combination of glass and ceramic materials.

[0006] To address the shortcomings of existing art glass, such as easy fading, weak adhesion, limited functionality, cumbersome processes, high energy consumption, and insufficient safety, a new type of glass-ceramic composite decorative glass is prepared, which combines high aesthetics, multiple optical functions, high-strength safety tempering, ultra-long weather resistance, and low carbon and energy saving, filling the market gap in integrated tempered decorative materials for building glass and ceramics.

[0007] (II) Technical Solution A method for preparing integrated glass-ceramic tempered stained glass includes the following steps: glass substrate pretreatment, preparation of a glass micropowder bonding protective layer, ceramic stained pattern forming, preparation of a functional optical layer, and high-temperature synchronous tempering and curing. The details are as follows: 1. Pre-treatment of substrate cutting High-quality float glass is selected as the base raw material, and it is precisely cut and shaped according to the specifications for architectural decoration. The glass edges are ground to remove burrs, flaws, and chipped edges, ensuring the flatness, dimensional accuracy, and edge smoothness of the glass.

[0008] 2. Preparation of High-Temperature Resistant Matching Glass Micropowder Slurry Prepare a glass micropowder solution with a melting temperature of 550℃~700℃. The coefficient of thermal expansion of the glass micropowder is perfectly matched with that of the float glass substrate. The particle size and specific gravity of the slurry are consistent with the parameters of ceramic inkjet ink. The spraying amount per unit area is 5~100mL / ㎡.

[0009] Glass micropowder was mixed with carboxymethyl cellulose suspending agent to form a stable suspension slurry, which served as a high-temperature bottom bonding transition layer and a top protective and anti-fouling layer.

[0010] 3. Double-layer coating molding process Method 1: Direct inkjet coating process A high-pressure spray gun or a modified ceramic inkjet machine is used to first spray a base layer of glass micro powder slurry onto the surface of the glass substrate. After drying and curing, a high-temperature transition bonding layer between glass and ceramic is formed. Above the adhesive layer, high-temperature ceramic inorganic color ink is sprayed using a ceramic-specific inkjet printer to print various decorative colored patterns such as marble texture, jade texture, landscape pattern, and figure pattern; simultaneously, functional inks such as emulsified soft light material, polarized optical material, and spectral light-absorbing heat insulation material are sprayed to give the glass emulsified diffusion, anti-glare polarization, energy-saving light-blocking and other multi-functional properties. After the painted and functional layers are formed, a surface glass micro powder slurry is sprayed on again to form a pattern protective layer and a stain-resistant protective layer.

[0011] Method 2: Transfer sticker lamination process Glass micro powder slurry, ceramic colored ink, and various optical functional inks are simultaneously inkjet printed onto organic transfer paper, and after being fully dried, they are precisely cut to the size of the glass. In the pre-glass tempering process, the transfer sticker is applied to the surface of the glass substrate, forming the adhesive underlayer, the painted pattern layer, and the functional optical layer simultaneously in one step.

[0012] 4. High-temperature integrated tempering molding After the layers are laminated and the stickers are applied, the glass to be processed is sent into a roller conveyor continuous glass tempering furnace, where it undergoes tempering heat treatment using conventional tempering temperatures and roller conveyor technology.

[0013] Under tempered high-temperature conditions, glass micropowder melts and tightly bonds with the substrate glass, achieving integrated glass-ceramic composite sintering; simultaneously, ceramic painting ink and functional optical materials are cured at high temperatures, completing glass tempering and strengthening, pattern painting and shaping, ceramic layer bonding, and permanent curing of the multi-functional layer in a single process.

[0014] (III) Beneficial Effects 1. Super weather-resistant and long-lasting color retention It uses high-temperature inorganic ceramic ink combined with glass micro powder for high-temperature fusion and curing, so the pattern will not peel off, oxidize, or fade. It is resistant to aging, ultraviolet rays, and acid and alkali corrosion for long-term use both indoors and outdoors, and its service life far exceeds that of traditional painted glass.

[0015] 2. Multifunctional optical decorative properties It can integrate multiple functions such as emulsified soft light, polarized anti-glare, light absorption and heat insulation, and diffused light transmission as needed, taking into account both decorative aesthetics and building lighting and energy saving, and is suitable for use in various scenarios such as curtain walls, floor-to-ceiling windows, background walls, and partitions.

[0016] 3. High-strength safety tempered performance The substrate undergoes complete tempering treatment, and after breaking, it forms obtuse-angled granules, making it explosion-proof and impact-resistant. Its safety performance meets the safety standards for architectural glass and is widely applicable to the exterior walls of high-rise buildings and high-end interior decorative finishes.

[0017] 4. Low-carbon, energy-saving, and streamlined processes Tempering, color curing, ceramic bonding, and functional layer shaping are all completed simultaneously in one step, reducing multiple heating stages and repeated processing steps, significantly reducing heat consumption and labor costs, and meeting the requirements of green building energy conservation and environmental protection development.

[0018] 5. Large-scale, efficient mass production It is compatible with tunnel-type continuous roller tempering furnace production lines, allows for diverse customizable patterns, ensures good batch consistency, has high production efficiency and low overall cost, and can be mass-produced on a large scale.

[0019] 6. Super strong adhesion between glass and ceramic. The glass micropowder has the same coefficient of thermal expansion as the substrate glass, and the high-temperature fusion eutectic bonding makes the ceramic painted layer less prone to peeling, cracking, and falling off. Its structural stability and interlayer bonding strength are significantly better than traditional post-filming and post-spraying processes. Attached Figure Description

[0023] 3. Use a high-pressure spray gun to evenly spray the bottom layer of glass micro powder slurry at a dosage of 5~100mL / ㎡, and let it air dry at room temperature or dry on a low-temperature roller to form a uniform high-temperature bonding transition layer.

[0024] 4. Using specialized ceramic inkjet equipment, paint a colored pattern with a jade texture on the surface of the adhesive layer, and simultaneously spray polarizing and anti-glare ink.

[0025] 5. Spray the glass micro powder surface layer slurry again to cover and protect the painted pattern, and after drying, send it into the roller tempering furnace.

[0026] 6. The glass is processed at high temperature according to the standard tempering parameters for float glass. During the tempering process, the glass micropowder melts and combines with the base glass, and the ceramic pattern and functional layer are simultaneously cured at high temperature. After cooling, tempered glass ceramic painted functional glass is obtained.

[0027] Example 2 1. The pretreatment of float glass cutting, grinding, and cleaning is the same as in Example 1.

[0028] 2. The glass micro powder paste, ceramic color pattern ink, and emulsified soft light functional ink are uniformly inkjet printed onto organic transfer paper and then fully dried and set.

[0029] 3. Cut the transfer sticker precisely according to the shape of the glass and adhere it tightly to the surface of the glass to be tempered.

[0030] 4. The glass is fed into a roller conveyor tempering furnace for high-temperature tempering, which completes the tempering and strengthening of glass, glass-ceramic fusion bonding, curing of painted patterns, and soft-light functional molding in one go, producing integrated glass-ceramic tempered decorative glass.

[0031] Example 3 A modified ceramic inkjet printer is used, with dedicated printheads added before and after the color ink channel. The front printhead sprays the glass micropowder base layer bonding ink, the middle printhead sprays the color painting and functional inks, and the rear printhead sprays the glass micropowder protective top layer ink. The unit area consumption is 5-100mL / ㎡. After drying, it is directly sent to the tempering furnace for integrated processing. The finished product has uniform layer sequence, excellent adhesion, and stable function.
