Abstract

The invention discloses an outdoor projection film and a preparation method therefor. The outdoor projection film comprises a plastic film layer, wherein a primer coating is arranged on the surface ofthe plastic film layer, and a semi-transparent resin layer is arranged on the surface of the primer coating; and a pressure-sensitive adhesive layer is arranged on the other surface of the plastic film layer, and a release film layer is arranged on the surface of the pressure-sensitive adhesive layer. The semi-transparent resin layer is prepared from the following raw materials: 100 parts of resin, 50-70 parts of solvent, 3-8 parts of cosolvent, 1-5 parts of curing agent, 5-15 parts of silica particles and 5-15 parts of titania particles. According to the outdoor projection film and the preparation method therefor, through additionally arranging the primer coating between the plastic film and the semi-transparent resin layer and can be used for improving the adhesive power of the semi-transparent resin layer to the plastic film, so that the outdoor projection film is not prone to aging spalling when the outdoor projection film is used in outdoor environments; and the pressure-sensitive adhesive layer is arranged at the other side of the plastic film, so that the end product can be stuck onto a sheet glass or polymethyl methacrylate (PMMA) sheet and forms a projection screen with the sheet glass or PMMA sheet, and the projection screen is more stable than the traditional movie screen and can be applied to outdoor advertisement projection.

Description

technical field [0001] The invention belongs to the field of film material preparation, and in particular relates to an outdoor projection film and a preparation method thereof. Background technique [0002] Existing projection screens for projectors are mostly used in indoor environments. If they are used in outdoor open-air environments, the existing screen materials in the market, such as PVC screens and glass fiber screens, all have problems. [0003] PVC screens age and turn yellow when exposed to sunlight, and long-term use affects the purity of projection colors; while glass fiber screens are only suitable for indoor use, and outdoor use also suffers from rain erosion, and the adhered dirt is difficult to remove, affecting the projection effect. Contents of the invention [0004] In order to solve the above technical problems, the present invention provides an outdoor projection film, which can meet the requirements for use in outdoor open-air environments. [0005...
