Description

Technical Field

[0001] This invention relates to the field of surface finishing technology for hyperboloid glass, and more particularly to a film application process for hyperboloid glass. Background Technology

[0002] To reduce the light transmittance of glass, or to protect it and provide functions such as heat insulation, UV blocking, glare reduction, decoration, privacy protection, and explosion protection, a film is often applied to the glass surface. The quality of the film application directly affects the performance and lifespan of the glass, and the application process is the key factor influencing the quality of the film. Therefore, finding a suitable application process is particularly important.

[0003] With the development of the automotive industry and the continuous improvement of automotive manufacturing technology, there is an increasing variety of high-tech, complex, and aesthetically pleasing window films for both interior and exterior car windows. These films can be installed not only directly inside the car but also in supporting charging and energy storage systems. The market demand for uniquely designed window films has surged, leading to increasingly higher requirements for their application processes. However, current methods for applying films to curved glass often involve manual application. This involves applying a pressure-sensitive adhesive or a pre-adhesive heat-sensitive adhesive film to a localized area on the inner and / or outer side of the curved glass, and then using a heat gun or other auxiliary tools to heat the film and gradually expel air bubbles to achieve the desired effect. This method is inefficient, has a low yield rate, and requires a high level of skill from the installer, making mass production difficult.

[0004] For example, Chinese invention patent application number 202111301496.2 discloses a glass surface coating film application process. This involves spraying a uniformly distributed layer of sterile water onto the surface of a glass sheet, then bonding a prepared film to the surface of the glass sheet fixed to a clamp, ensuring accurate adhesion between the film and the glass sheet. The coated glass sheet is then left to stand, and a hot air blower is used to heat and bake it to set its shape. However, this process has low production efficiency, is prone to air bubbles, affecting the film application quality. Furthermore, the adhesion strength between the glass and the film is insufficient, leading to film separation after prolonged use.

[0005] It is evident that developing a film-applying process that is highly efficient and of high quality, can perfectly bond the film texture to hyperboloid glass, has a high yield rate, and enables mass production of coated hyperboloid glass meets market demands. This process has broad market value and application prospects, and is of great significance for promoting the development of the hyperboloid glass surface finishing industry. Summary of the Invention

[0006] The main objective of this invention is to provide a film application process that is highly efficient and of good quality, can perfectly bond the textured surface of the film to the glass, has a high yield, and can enable mass production of hyperboloid glass.

[0007] To achieve the above objectives, the present invention provides a film application process for hyperboloid glass, comprising the following steps:

[0008] Step S1, Selection of membrane: Select a membrane with a surface texture depth of 5-20µm;

[0009] Step S2, coating the membrane surface with adhesive: apply adhesive to the textured surface of the membrane by scraping, with a coating thickness of 25µm-50µm, and bake at 60-80℃ for 10-15min;

[0010] Step S3, Installing the film and hyperboloid glass: Place the hyperboloid glass to be filmed on the fixture table of the lower chamber of the TOM equipment, then place the film with glue applied to the textured side on the film frame plate between the upper and lower frames. After closing the upper and lower chambers, evacuate to 0.02KPa-0.2KPa, and then heat the film.

[0011] Step S4, Diaphragm Application: Maintain the pressure inside the lower chamber between 0.02 kPa and 0.2 kPa, pressurize the upper chamber to a certain pressure, and simultaneously lift the fixture platform; then, after maintaining the pressure in both the upper and lower chambers for a certain period of time, first depressurize the upper chamber at a rate of 1-10 kPa / s. When the pressure display of the upper chamber shows 100-103 kPa, depressurize the lower chamber at a rate of 1-10 kPa / s. When the pressure display of the lower chamber shows 100-103 kPa, the diaphragm application on the hyperboloid glass is complete.

[0012] Preferably, the adhesive in step S2 is prepared by uniformly mixing the following components in parts by weight: 18-35 parts of isooctyl acrylate, 5-10 parts of methyl methacrylate, 1-3 parts of methyl 5-allyl-3-methoxysalicylate, 1-3 parts of N-vinyloxazolidinone, 0.8-1.2 parts of 2-methyl-N-[2-(2-oxo-1-imidazolyl)ethyl]-2-acrylamide, 0.6-1 part of acrylic acid, 0.8-1.2 parts of N-acryloyl(tris(hydroxymethyl)aminomethane), 1-3 parts of other monomers, 0.5-2 parts of hexamethylene diisocyanate, 0.1-0.2 parts of initiator, and 48-62 parts of solvent.

[0013] Preferably, the solvent is at least one of ethyl acetate, acetone, and toluene.

[0014] Preferably, the initiator is at least one selected from benzoyl peroxide, azobisisobutyronitrile, and dicumyl peroxide.

[0015] Preferably, the other monomers are at least one of tricyclo[5.2.1.02,6]dec-8-yl methacrylate, allyl succinimide carbonate, and 3-(1,1-difluoro-2-propen-1-yl)-2(1H)-quinoxalone.

[0016] Preferably, the heating temperature in step S3 is 100-130°C and the heating time is 90-110 seconds.

[0017] Preferably, the TOM device mentioned in step S3 is a TOM small device 548-348, provided by Zhejiang Shirui Qitan Technology Co., Ltd.

[0018] Preferably, the pressure mentioned in step S4 is 50-150 kPa.

[0019] Preferably, the certain time in step S4 is 10-15 seconds.

[0020] Due to the application of the above technical solution, the present invention has the following beneficial effects:

[0021] The film-applying process for hyperboloid glass disclosed in this invention uses the pressure difference between the upper and lower chambers to bond the film to the hyperboloid glass. The pressure used is 50Kpa-150Kpa, which will not cause the glass to break due to excessive force. At the same time, the pressure in the lower chamber is maintained at 0.02KPa-0.2Kpa for a certain period of time, which is conducive to the expulsion of air between the film and the glass, so that the film and the glass surface can be perfectly bonded.

[0022] The film-applying process for hyperboloid glass disclosed in this invention uses overall film baking, which allows for multiple production from a single film, resulting in high forming efficiency and enabling mass production. It eliminates the reliance on manual experience and techniques, and the main parameters are set by the equipment, ensuring consistency. The high temperature only heats the film separately, without affecting the strength of the glass.

[0023] The film-coating process for hyperboloid glass disclosed in this invention involves pre-coating the film surface with adhesive, allowing the adhesive to fully penetrate the texture of the film, facilitating a tight bond between the film and the hyperboloid glass, effectively reducing the generation of air bubbles, and thus improving the stability of the product and making it less prone to detachment. The adhesive is prepared by uniformly mixing the following components in parts by weight: 18-35 parts isooctyl acrylate, 5-10 parts methyl methacrylate, 1-3 parts methyl 5-allyl-3-methoxysalicylic acid, 1-3 parts N-vinyloxazolidinone, 0.8-1.2 parts 2-methyl-N-[2-(2-oxo-1-imidazolyl)ethyl]-2-acrylamide, 0.6-1 part acrylic acid, 0.8-1.2 parts N-acryloyl(tris(hydroxymethyl)aminomethane), 1-3 parts other monomers, 0.5-2 parts hexamethylene diisocyanate, 0.1-0.2 parts initiator, and 48-62 parts solvent. Through the synergistic effect of the various components and the orderly arrangement of the film application process steps, the bonding quality between the film and the hyperboloid glass is improved, resulting in a high degree of adhesion between the film and the hyperboloid glass.

[0024] The film-applying process for hyperboloid glass disclosed in this invention, through the rational selection of adhesive formulation, simultaneously introduces ester groups, salicylic acid, oxazolidinone, amide, imidazolidinyl, hydroxyl, tricyclic [5.2.1.02,6]dec-8-yl ester, succinimide carbonate, and fluoroquinoxalone structures into the molecular structure of the adhesive. The synergistic effect of these structures not only significantly changes the distance and morphology between adhesive molecules, resulting in a significant improvement in its thermal stability, but also effectively improves the overall aging resistance of the product, making the adhesion between the glass and the film stronger, thereby extending the service life of the product.

[0025] The film application process for hyperboloid glass disclosed in this invention, combined with the selection of a specific adhesive formula, enables the film to remain intact for more than 1 hour under boiling conditions at 100°C without peeling off, without bubbles, and without edge shrinkage. Furthermore, the film does not peel off after a 3*3mm cross-cut test following boiling, demonstrating excellent product durability. Detailed Implementation
