Abstract

The invention relates to the technical field of imaging display, in particular to a projection screen coating paint, a preparation method and a coating forming method so as to achieve the technical purposes that the preparation process is simple and mature, the forming mode is convenient to implement and good optical performance is achieved. According to the technical scheme adopted for achieving the technical purposes, the projection screen coating paint is prepared from, by mass, 65%-75% of self-crosslinking water-soluble resin, 3%-5% of a solvent, 8%-10% of a coalescing agent, 0.3%-0.5% of a defoaming agent, 0.3%-0.5% of a flatting agent, 0.3%-0.5% of thickening agent, 0.1%-0.3% of a dulling agent, 0.1%-0.3% of a preservative, 5%-8% of filler and 1%-3% of a coloring agent. The projection screen coating paint, the preparation method and the coating forming method are especially applied to projection screen production.

Description

technical field [0001] The invention relates to the technical field of imaging and display, in particular to a projection screen coating, a manufacturing method and a coating forming 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 projected picture, but also promotes color reproduction and contrast. The quality of the screen directly determines the perfection of the projected picture. As a complete projection display system is an essential component, the current common projection modes include front projection and rear projection. [0003] According to different optical characteristics, the projection screens on the market are mainly classified into: 1. Scattering screens - common varieties are relatively cheap white plastic screens, gray plastic screens and metal screens are improved products that improve ...
