Problems solved by technology

[0005] The purpose of the present invention is to overcome the problem that most of the elastic particles in the coated reflective film in the prior art will be wrapped by the adhesive, which affects the scratch resistance and anti-adsorption performance, and provides a layered coating type scratch-resistant coated reflective film and the preparation method thereof, the mixed adhesive and elastic particles are layered and coated on the surface of the reflective base film, and the viscosity difference between the two layers of coating liquid can make the coated elastic particles semi-exposed on the coating surface, thereby improving the reflective film. Scratch resistance can prevent elastic particles from falling off

Abstract

The invention discloses a layered coating type scratch-resistant coating reflecting film and a preparation method thereof. The scratch-resistant coating reflecting film comprises a reflecting base film, a mixed adhesive layer arranged on the reflecting base film and an elastic particle layer positioned on the surface of the mixed adhesive layer, the mixed adhesive layer coating liquid comprises the following components in percentage by mass: 10-15% of a polyacrylate adhesive, 20-30% of an organic silicon resin adhesive, 0.5-1% of a curing agent, 1-1.5% of a silane coupling agent and the balance of a solvent; the elastic particle layer coating liquid comprises the following components: 20-30% of elastic particles, 15-20% of a polyacrylate adhesive, 1-2% of a curing agent and the balance of a solvent. According to the invention, the mixed adhesive and the elastic particles are coated on the surface of the reflective base film in a layered manner, and the coated elastic particles can be half exposed on the surface of the coating through the viscosity difference of the two layers of coating liquid, so that the scraping resistance of the reflective film is improved, and the elastic particles are prevented from falling off at the same time.

Description

technical field [0001] The invention relates to the technical field of optical reflective films, in particular to a layered coating type scratch-resistant coating reflective film and a preparation method thereof. Background technique [0002] The backlight module is the provider of the light source of the liquid crystal display. It is mainly composed of a light source, a light guide plate, an optical film, a plastic frame, etc. The optical films used mainly include reflective film, brightness enhancement film and diffusion film. At present, there are mainly three types of backlight modules: EL, CCFL and LED, which are classified into side-lighting and direct-lighting (bottom-lighting) according to the distribution position of the light source. In the application of the edge-type backlight module, since the reflective film is close to the light guide plate, there is the possibility of attracting the light guide plate, and the direct contact between the light guide plate and t...
