Screen material, sprinkler device, projection screen device and use method thereof

Abstract

The present invention mainly provides a screen material, a sprinkler device, a projection screen device and a method of using the same, and mainly provides an application in which at least one projection device can display an image after projection. The projection screen device comprises a substrate, and at least one screen coating layer which is formed by applying a liquid screen coating to the preset portion of the surface of the substrate. The composition and weight percentage of the screen coating are: water-soluble polyurethane 20%-30%, water-soluble acrylic resin 20%-30%, silica powder 20%-30%, sodium polyacrylate thickener 2%-5%, silicone emulsion defoamer 2%- 5%, water-soluble emulsified wax 2%-5%, acrylic polymer solution 2%-5% and pure water. By using the above-described technique, the screen material having the characteristics of the water-soluble paint is coated on a substrate of any material, the projection screen is formed as a positive projection and a back projection, and the image display has high quality, high-definition and high-resolution effect, so the application is quite extensive.

Description

technical field [0001] The present invention relates to a projection screen technology, in particular to projecting through a projector in a space and displaying images on it, which is suitable for both front projection and rear projection, and is coated with liquid screen paint on any Screen material, sprinkler irrigation device, projection screen device and method of use formed on substrate. Background technique [0002] Image Projection, also known as image projection, mainly uses a light source device and an optical device to project an image or image on a projection screen. The displayed image or image can be displayed on the projection screen for different positions. The image or image can be enlarged and displayed at the same time. Currently, such image projection technologies and devices are widely used in business presentations or conferences, classrooms, exhibition venues, home theaters or games, theaters, entertainment game venues, or multimedia applications. ...

AI Technical Summary

Problems solved by technology

[0012] However, the above-mentioned prior art "paint-type" projection screen technology is limited to the use of front projection, and cannot be applied to the transmissive projection screen of rear projection at the same time, and does not have the dual-use effects of front projection and rear projection; and the existing projection screen is being manufactured. Sometimes it needs to be baked, which needs to be carried out with high-temperature baking equipment, which consumes electricity and costs, and is not environmentally friendly; on the other hand, it needs to be prepared with professional coating equipment and heating or baking equipment. It is impossible to purchase screen paint by yourself and apply it on the existing substrate or the required substrate, or the existing furniture or wall surface, especially the coating operation cannot be completed at room temperature, so the use is limited; and , most of the projection screen coating layers in the prior art are based on oily paint, which is prone to volatilization of poisonous gas. During the screen coating process and coating process, it will cause environmental pollution, and waste gas or waste water treatment devices need to be added, resulting in cost quite high
