Abstract

The invention discloses a functional layer coating material of a projection curtain. The functional layer coating material comprises the ingredients in parts by weight: 70-80 parts of PVC resin, 40-50parts of ethyl acetate, 15-22 parts of impregnating compound, 5-8 parts of citrate plasticizer, 4-8 parts of ultraviolet absorbent, 1-2 parts of delustrant and the balance of auxiliaries. The invention further discloses the projection curtain. The projection curtain comprises a basal layer, a water vapor barrier layer and a functional layer, wherein the water vapor barrier layer and the functional layer are arranged at one side of the basal layer. According to the functional layer coating material of the projection curtain, disclosed by the invention, the brightness and contrast of the projection curtain can be obviously improved, and thus, the projection curtain can show bright projection colors. Meanwhile, the projection curtain has a water vapor barrier layer for blocking water vapor,thereby having good humidity resistance. The production method of the projection curtain, disclosed by the invention, is simple and is applicable to 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 preparation method thereof. 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 ambi...
