Embodiment 1
[0044] refer to figure 1 , in this embodiment, a mixed film for the wall of the soft film display is proposed, including the water-based wall solution 2, the A-side hydrosol 3, the support member 4, the B-side non-aqueous sol 5 and the non-aqueous wall solution 6 .
[0045]The water-based wall lotion 2 is used to smear on the object. The water-based wall lotion 2 can include 70 parts of the first solvent, 10 parts of the second solvent, 20 parts of the first polymer binder, and 20 parts of the second polymer 10 parts of binder, 0.2 part of first thermosetting agent, 0.1 part of first dispersant and 0.1 part of first defoamer, but not limited thereto. The object to be pasted can be wall surface 1, glass wall, billboard, billboard, acrylic board, steel plate, etc., without limitation.
[0046] The first solvent can dissolve the water-based polymer binder, and the water-based polymer binder is also a hydrosol. The first solvent may be pure water or ultrapure water, but not lim...
Embodiment 2
[0068] refer to Figure 2 ~ Figure 3 , the installation steps of the soft film display screen 7 can be:
[0069] S1. On the pasting surface of the soft film display screen 7, lay the non-aqueous upper wall potion 6, the B-side non-aqueous sol 5 and the support 4 in sequence, and finally cover the A-side water sol 3. The pasting surface is the display unit surface for the soft film display screen 7 .
[0070] S2. Use lamination, lamination, and autoclave methods, vacuumize (negative atmospheric pressure), and heat at a temperature of 90°C to 150°C for 10-240 minutes to make non-aqueous wall potion 6. Surface B is non-aqueous The layers of the sol 5 and the support 4 are combined.
[0071] S3. Use the water-based wall potion 2 to cover the side A with the water sol 3 on the adhesive-attached support 4 and stick it to the wall 1 .
[0072] The installation steps of the soft film display screen 7 can also be:
[0073] S1. Apply the water-based wall lotion 2 on the object to be...
Embodiment 3
[0080] In this embodiment, a method for installing the water-based wall lotion 2 in the wall mixing film for soft film display screens is proposed, including the following steps:
[0081] Stir the first solvent, and slowly add the first polymer binder so that it does not agglomerate or accumulate to accelerate dissolution; after the first polymer binder is swollen; slowly add the second solvent to dissolve it; Heating, stirring and slowly adding the second polymer binder to make it dissolve. At this time, the dissolution time can be shortened by raising the temperature; using this dissolution method, the formation of Lump PVB can be avoided (because the dissolution time will be several times stronger after the Lump PVB is formed), and thus the dissolution rate can be accelerated. The ratio of aromatic solvents to alcohol solvents is 60 / 40-40 / 60 (weight ratio), and PVB solutions with lower viscosity can be formulated. The solvent composition contains 2-3 wt% of water, which ca...
