Problems solved by technology

[0009] However, when the adhesive-coated screen is rolled up in a roll, the rolled-up part may stick to the adhesive
[0010] Therefore, there may be a problem that it is difficult to unroll after being rolled up in the shape of a roll
[0011] In addition, due to repeated bonding and peeling, not only does the adhesive layer stick to foreign matter, thereby reducing the adhesive force, but also when it is used in a screen panel, foreign matter gradually adheres to the screen, thereby reducing the image quality.

preparation example Construction

[0045] As a preparation example of nano-silica microparticles, add acid to silicic acid to form a silica sol, and continuously add acid to the silica sol, so that the silanol groups (Si- OH), promote the sharp dehydration condensation reaction caused by acid, form Si-O-Si network and form silica gel with three-dimensional network structure.

[0046] Afterwards, water washing and drying processes are carried out to control the physical properties, and finally micro-differentiation is carried out, so that nano-silica particles can be prepared.

[0047] The nano-silica particles prepared by the above method are in the form of powder, and when mixed with a peeling binder, the stability can be ensured, thereby maintaining the internal stability of the paint.

[0048] Furthermore, the nano-silica particles prepared by the above method not only transmit the light of the beam projector 3 according to the light diffusion, thereby providing a clear image, but also disperse the light in ...

Abstract

The invention relates to a light beam projector display screen for illuminating by using easily removable coating, especially relates to a display screen of an illumination beam projector, the above light beam projector display screen for illuminating comprises: a plate-shaped component (1a); a removable coating which coats the above plate-shaped component (1a) that is solified, so that a non-transparent or translucent coating film layer (2) is formed, the removable coating can be removed after set time after solidifying or by contacting with water after solidifying, thus the removable coating is removable and comprises silica fine particles.

Description

technical field [0001] The present invention relates to a display screen for beam projector illumination using an easily removable paint. Background technique [0002] The present invention proposes to use the image of the beam projector not to simply watch movies, but to improve the effect of advertising and publicity. [0003] As an example, "High Brightness Image Screen Panel Utilizing Transparent Glass" (Korea Registered Utility Model Publication No. 20-0273709, Patent Document 1) discloses a translucent fine particle sheet paper and Transparent glass, and the image of the beam projector shines on the thin paper, thereby utilizing the technology of the image screen panel. [0004] However, in order to illuminate the light of the beam projector to form an image frame on the screen panel, the screen panel should be an opaque or minimally translucent screen panel. [0005] At this time, when the object of the screen board is located at the boundary between the inside and ...
