Problems solved by technology

With the application of laser light source movie projectors, the requirements for the screen have also changed. The brightness coefficient of the screen can be appropriately reduced on the original basis, and it becomes more important to improve the effective scattering angle of the screen. The ratio index and the uniformity of the surface are also very important, and the traditional screen can no longer meet the needs of use

Abstract

The invention relates to low-gain and large-scattering angle metal film screen optical coating material, a preparation method and a spraying method thereof, wherein the components comprise, by mass, 30-35% of a A450 resin, 22-27% of flaky aluminum powder, 3-7% of a leveling agent, 3-4% of polysiloxane, 11-15% of overweight fine calcium carbonate, 5-8% of fumed silica, 1-2% of di-tert-butyl dimethylamino p-cresol, 7-10% of a N75 curing agent, 1-2% of methyl silicone oil, and 2-4% of a halogen-free flame retardant agent. According to the film screen treated through the preparation method and the spraying method, the effective scattering angle of the film screen is improved, the polarization ratio index of the film screen is ensured, the gain is reduced, the uniformity of the film screen surface is ensured, and the service life of the film screen is prolonged.

Description

technical field [0001] The invention relates to a screen optical coating, in particular to a metal screen optical coating with low gain and large scattering angle, a preparation method and a spraying method thereof. Background technique [0002] Screen, which refers to the white screen that displays the projection when playing a movie, is more common in many movie theaters and amusement parks. The viewing effect of movies is also affected by the quality of the screen to a certain extent. For example, the gain of the screen is the reflection ability of the screen to light, which is determined by the surface material of the screen. The main materials used in the market are white plastic, glass beads and metal curtains. Gain ranges from 0.8 to 2.4. With the application of laser light source movie projectors, the requirements for the screen have also changed. The brightness coefficient of the screen can be appropriately reduced on the original basis, and it becomes more import...
