Embodiment 1

[0047] A self-cleaning curtain wall decorative panel in this embodiment, combined with figure 1 , consisting of substrate layer 1, passivation layer one 2, passivation layer two 3, primer layer 4, topcoat layer 5, self-cleaning layer 6 and back paint layer 7, passivation layer one 2, passivation layer two 3 Located on the lower surface and the upper surface of the substrate layer 1 respectively, the back paint layer 7 is located below the passivation layer 1 2, the primer layer 4 is located on the passivation layer 2 3, the primer layer 4, the top coat layer 5 and the self-cleaning layer 6 Arranged sequentially from bottom to top; the self-cleaning layer 6 is a film-like fluoropolymer 61 formed by a water-soluble fluoropolymer, wherein nanoscale titanium dioxide or titanium dioxide / silicon dioxide are prepared by sol-gel method to form titanium dioxide (or Titanium dioxide / silica composite) gel 62. Specifically in this embodiment, the titanium dioxide (or titanium dioxide / sil...

Embodiment 2

[0057] The setting and working principle of this embodiment are the same as that of Embodiment 1, the difference lies in: combining figure 2 , the fluoropolymer 61 is provided with multiple layers, in the fluoropolymer 61, the titanium dioxide (or titanium dioxide / silica composite) gel 62 is granular, and the titanium dioxide (or titanium dioxide / silica composite) gel 62 is embedded in The titanium dioxide (or titanium dioxide / silica composite) gel 62 between the top layer and the bottom layer of the fluoropolymer 61 and the multilayer fluoropolymer 61 form a self-cleaning layer 6 .

Embodiment 3

[0059] The setting and working principle of this embodiment are the same as that of Embodiment 1, the difference lies in: combining image 3 , titanium dioxide (or titanium dioxide / silica composite) gel 61 is a layered structure, the titanium dioxide (or titanium dioxide / silica composite) gel 62 is a strip or layered structure, which is located in the fluoropolymer 61 , titanium dioxide (or titanium dioxide / silicon dioxide composite) gel 62 and fluoropolymer 61 form a self-cleaning layer 6 .

Abstract

The invention relates to a self-cleaning curtain wall decorative sheet and a manufacturing technique thereof and belongs to the technical field of building materials. The self-cleaning curtain wall decorative sheet is composed of a substrate layer, a first passivation layer, a second passivation layer, a backing paint layer, a primer layer, a finish paint layer and a self-cleaning layer. The first passivation layer and the second passivation layer are located on the lower surface and the upper surface of the substrate layer correspondingly. The backing paint layer is located under the first passivation layer. The primer layer is located on the second passivation layer. The primer layer, the finish paint layer and the self-cleaning layer are sequentially arranged from bottom to top. The self-cleaning layer is a titanium dioxide / silicon dioxide composite layer, and fluoropolymer formed by water-soluble fluorine-containing polymer is arranged in the self-cleaning layer. The self-cleaning curtain wall decorative sheet is applied to the building decoration field such as high-rise building outer walls and large exhibition halls and has the advantages of weather resistance, corrosion resistance, self-cleaning and the like.

Description

technical field [0001] The invention relates to a self-cleaning curtain wall decorative board and a processing technology thereof, belonging to the technical field of building materials. Background technique [0002] With the upgrading of material manufacturing technology and equipment, people's aesthetics and quality requirements, fluorocarbon aluminum veneer itself has light weight, high rigidity, high strength, high flame retardancy, high weather resistance, acid and alkali resistance, and color options. Wide, can be processed into various complex shapes, good decoration; high recycling value, factory production, convenient construction and other advantages, making it the main building material for various high-end buildings such as high-speed rail stations, exhibition halls, gymnasiums, and high-end residential buildings. The application and development of curtain wall decoration materials and fluorocarbon aluminum veneer has been rapidly improved. [0003] With the dev...
