Description

Technical Field

[0001] This invention relates to the field of tempered glass appearance processing technology, specifically to a glass production process based on ordinary screen printing. Background Technology

[0002] The glass industry is constantly evolving, and glass processing techniques have largely settled into traditional methods such as standard colored crystal, KMI, HTMI (screen printing type UV), TMI, and high-temperature printing. However, with the increasing number of product models, the demand for glass is also constantly growing, while the cost of glass surface processing is continuously rising. Traditional high-temperature processes require color matching of untempered glass, and the color changes significantly after tempering in a furnace, resulting in poor consistency and difficulty in color control. Furthermore, due to the large amount of filler in the ink, traditional high-temperature processes often lead to low yield, low production efficiency, and screen damage during printing.

[0003] Therefore, this solution provides a glass production process based on ordinary screen printing to achieve the same effect as some high-temperature processes and some HTMI processes. Summary of the Invention

[0004] The purpose of this invention is to provide a glass production process based on ordinary screen printing, which solves the technical problem of how to achieve the same technical effect as some high-temperature processes and some HTMI processes in glass appearance processing in a low-cost and high-efficiency manner. This results in thin glass layers, simple operation, high output, and no screen damage during printing. Compared with the existing technology, this is a major breakthrough and innovation in glass appearance processing.

[0005] A glass manufacturing process based on conventional screen printing includes the following steps; Step 1: Apply a gold or gray base seal to the non-tempered glass; Step 2: Process the product obtained in Step 1 using a tempering process; Step 3: Apply a single-layer base coat to the tin surface of the product from Step 2. Specifically, apply UV varnish to the glass tin surface and bake at 180 degrees Celsius to apply the base coat to the HTMI layer. Step 4: Apply a thin-layer HTMI texture to the tin surface of the product from Step 3; Step 1 specifically includes the following steps: Step 1.1: Use general-purpose abrasion-resistant protective primer ink and general-purpose platinum ink, mix them to a metallic color, and print on the air surface of the glass; Step 1.2: For the air surface of the product obtained in Step 1.1, perform a baking and curing process at 180℃.

[0006] Step 3 specifically includes the following steps: Step 3.1: Apply UV varnish to the tin surface of the product obtained in Step 2 for printing processing. Step 3.2: The tin surface of the product obtained in Step 3.1 is subjected to a baking and curing process at 180℃.

[0007] Step 4 specifically includes the following steps: Step 4.1: Using UV ink, print the tin side of the product obtained in Step 3.2 onto the surface of the UV varnish; Step 4.2: Perform screen printing to create patterns and textures that can only be obtained through traditional high-temperature processes; Step 4.3: Use a UV curing machine to perform a UV curing process on the screen-printed pattern texture.

[0008] The UV varnish used in step 3 contains a curing accelerator.

[0009] In step 4, rare earth luminescent materials are added to the UV ink.

[0010] In step 3, the UV varnish has 2-3 layers.

[0011] In step 4, the UV ink has 2-3 layers.

[0012] The positive effects of this invention are as follows: (1) The thin-layer HTMI process in this scheme is a low-temperature product. Compared with some high-temperature and some HTMI products, it has the same appearance effect, and has advantages such as strong operability, high product yield, high work efficiency and low cost. It can replace some high-temperature processes and HTMI processes.

[0013] (2) Use general wear-resistant protective primer ink and general platinum ink to make a metallic color and print it on the air surface of the glass. After baking at 180 degrees, the glass has a metallic feel, protects the glass, prevents the glass from being scratched, and can also be used as a foaming adhesive for products such as refrigerators and air conditioners.

[0014] (3) Since all appearance operations and parameter control are carried out after tempering, there will be no inconsistency between the appearance before and after tempering in the traditional high temperature process, thus the product stability is superior to that of the traditional high temperature process.

[0015] (4) Because the UV ink is printed on the last layer in the thin-layer HTMI process of this application, subsequent production changes and derivative product production will be much more convenient. Attached Figure Description
