Abstract

The invention discloses a functional layer coating of a projection curtain. The functional layer coating comprises the following components in parts by weight: 50-60 parts of polyester modified silicon resin, 20-28 parts of absolute ethyl alcohol, 10-12 parts of glass beads, 2-5 parts of a flame retardant and 1-2 parts of a thickening agent. The invention also discloses a projection curtain, whichcomprises a substrate layer, and a protective layer and a functional layer which are arranged on one side of the substrate layer. According to the functional layer coating for the projection curtain,the brightness and the contrast ratio of the projection curtain can be obviously improved, the projection curtain shows bright projection colors, and the gain can reach 1.03. Meanwhile, the projection curtain is not easy to damage and has excellent corrosion resistance and wrinkle resistance. The manufacturing method of the projection curtain is simple and suitable for industrial production.

Description

technical field [0001] The application belongs to the field of projection, and in particular relates to a functional layer coating of a projection screen, a projection screen and a manufacturing method. Background technique [0002] The exquisite picture perceived by the human eye is intuitively displayed on the projection screen. A high-quality screen not only needs to realize the complete reproduction of the projection screen, but also promotes color reproduction, brightness, and contrast. The quality of the screen directly determines the perfection of the projection screen. degree. Existing projection screens have problems such as unclear projected content, uneven brightness of projected content, and low brightness gain, which cannot satisfy the audience's desire for intuitive quality effects. [0003] Existing projection screens still have problems such as low brightness, low contrast, low resolution, and narrow viewing angle. The screen is easily affected by ambient li...
