Abstract

The invention discloses a composite acrylic transparent film comprising, from top to bottom, a transparent protective film, a low-viscosity movable sensitive adhesive, a composite acrylic transparent film, a metal deposited layer, a high-temperature-resistant pressure-sensitive adhesive, and a PET release film. Also, the invention discloses a preparation method of the composite acrylic transparent film, and an application thereof in three-dimensional vacuum forming. The composite acrylic transparent film provided by the invention has good outdoor weatherability, high-temperature forming performance, and high light transmittance under backlight.

Description

technical field [0001] The invention relates to a film coated with pressure-sensitive adhesive, especially a composite acrylic transparent film. The film can be used to make various light-transmitting metal appearance signs. The film is a self-adhesive film that can be used for vacuum suction film with bright silver effect. In addition, the present invention also relates to the preparation method and application of the film. Background technique [0002] Many clear films are back-laminated for a bright silver effect. Selecting the appropriate coating thickness can achieve excellent light reflection and better light transmittance; selecting the appropriate film can provide excellent outdoor weather resistance and good high-temperature plastic absorption performance. Such a film can be suitable for the application of a three-dimensional blister backlit light box. The blister logo made of this bright silver film has the texture of stainless steel during the day, but at night...
