Description

Technical Field

[0001] The utility model relates to the field of construction, and more specifically to a thermal transfer membrane surface paving structure. Background Art

[0002] Pictures and texts need to be displayed in building exterior walls, beams, balconies, terminals, car buildings, conference halls, opera houses, stadiums, reception halls, characteristic blocks and other places. Among them, characteristic blocks adopt the design concept of culture into the street, industry into the market, water into the city, and beautiful scenery into the heart. Characteristic blocks rely on national culture, improve the tourism chain, enrich consumption scenes, integrate multiple elements of "food, accommodation, transportation, travel, shopping, and entertainment", and create an open, low-density style street and a city of lights.

[0003] In addition, in order to meet customer needs, building materials also need to be developed according to customer preferences.

[0004] The existing method is to spray a layer of fluorocarbon paint on the surface of building materials. Although it has the advantages of bright colors and the ability to freely mix various colors, it has the disadvantages of high cost, easy to fall off, and difficult to install.

[0005] Thermal transfer is a new printing process that has been introduced from abroad for only more than 10 years. The printing method of this process is divided into two parts: transfer film printing and transfer processing. Transfer film printing adopts dot printing (resolution up to 300dpi), and the pattern is pre-printed on the surface of the film. The printed pattern is rich in layers, bright in color, ever-changing, with small color difference and good reproducibility, which can meet the requirements of the designer and is suitable for mass production; transfer processing uses a thermal transfer machine to process (heating and pressurizing) to transfer the exquisite pattern on the transfer film to the surface of the product. After forming, the ink layer is integrated with the surface of the product, which is realistic and beautiful, greatly improving the grade of the product. Utility Model Content
