Abstract

Belonging to the technical field of preparation of waterborne astigmatic screen paint, the invention specifically discloses a preparation method of a waterborne astigmatic screen paint. The preparation method of the waterborne astigmatic screen paint specifically includes the steps of: S1: activating a polyurethane resin emulsion: adding the polyurethane resin emulsion into the stirring tank of adispersion machine, starting the dispersion machine, and setting the rotating speed of the dispersion machine at 500r / min to activate the molecules of the polyurethane resin emulsion; S2: performing secondary feeding and dispersion; S3: adding tailings and performing mixing further; S4: conducting sampling and detection; and S5: preparing a finished product. The prepared waterborne astigmatic screen paint has evenly distributed light diffusion agent, after the paint forms a film, the light diffusion agent is balanced, the phenomenon of gathering in the screen coating does not occur easily andleak holes do not appear easily; the image is clear and lifelike, and the imaging coefficient is high; and the paint can be applied to rear projection screens, and the imaging definition is consistentwith that of an orthographic projection screen.

Description

technical field [0001] The invention relates to the technical field of water-based astigmatism screen coating preparation, in particular to a water-based astigmatism screen coating. Background technique [0002] Screen paint walks on hard and soft substrates, and when the projector is projected onto the screen, the screen presents an image. [0003] Cavity screen paint is widely used on soft screens and hard screens. Soft substrates include screens, inflatable PVC splicing balls, and hard substrates include walls, ceilings, projections inside and outside the sphere, and can achieve certain imaging effects. [0004] In the existing method of preparing screen coatings, the astigmatizing agent is not uniformly distributed during use, resulting in holes and clusters during use, and the screen imaging is not clear enough. Contents of the invention [0005] The object of the present invention is to provide a water-based astigmatism screen coating to solve the problem that the a...
