Abstract

The invention discloses an outdoor projection film and a preparation method thereof. There is a pressure-sensitive adhesive layer, and the surface of the pressure-sensitive adhesive layer is provided with a release film layer. The semipermeable resin layer is made of the following raw materials: 100 parts of resin, 50-70 parts of solvent, 3-8 parts of co-solvent, 1-5 parts of curing agent, 5-15 parts of silica particles and 5-15 parts of titanium dioxide particles . In the present invention, by adding an undercoat layer between the plastic film and the semipermeable resin layer, the undercoat layer can improve the adhesion of the semipermeable resin layer to the plastic film, making it difficult to age and fall off when used in an outdoor environment; A pressure-sensitive adhesive layer is set on the other side so that the final product can be attached to a glass plate or a polymethyl methacrylate (PMMA) plate to form a projection screen with the glass plate or PMMA plate, which is more stable than a traditional movie screen. Can be used for outdoor advertising 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...
