Problems solved by technology

[0006] On the other hand, in order to achieve high-grade screens, although there are attempts to apply coatings using adhesive sheets, paints, and optical materials, they actually cause high prices and cause release of dangerous VOC substances and fires during coating. Wait
In addition, in order to manufacture screens on large glass, when coating the coating liquid, a large amount of VOC substances are used for disposal, causing environmental pollution and accidents

preparation example Construction

[0042] 1. The preparation method of coating liquid composition (comparative example, embodiment same, common)

[0043] Put the resin and liquid raw materials into the cylindrical paint production container, use a dissolver capable of high-speed dispersion to stir evenly at 500-1000RPM for 30 minutes, then put silicon oxide and hollow nano-titanium oxide in sequence , and disperse and stir at a high speed of 1200-1700 RPM for 2 hours, thereby preparing a VOC-free coating liquid composition for image formation.

[0044] 2. Substrate: glass plate Size: 450mm*600mm, thickness 3mm

[0045] 3. Coating method for projector screen

[0046] (1) Coating tool used: planetary roller (used to make the thickness of 100% water-soluble paint or coating film thinner)

[0047] (2) Thickness of dry coating film: 30-40μm (coating twice, the second coating after 60 minutes after the first coating)

[0048] (3) Drying time (24 hours at 25°C)

Abstract

Provided is a VOC-free coating liquid composition for image formation, which is used in a rear projection beam projector screen. The coating liquid composition comprises a water-soluble acrylic polymer, hydrophilic ethylene glycol with a hydrophilic chain segment, a nonionic emulsifier, hollow nano titanium oxide, wet-process non-spherical porous silicon oxide and water.

Description

technical field [0001] The present invention relates to a VOC-free coating liquid composition for image formation which is used in a rear projection type beam projector screen and makes volatile organic compounds (VOC) close to zero. Background technique [0002] In the rear projection type beam projector screen, after applying a translucent coating material to a transparent substrate, various random reflections and low reflections are produced according to the particle structure and refractive index, and the coating film is applied when projecting a beam. A technique for composing images for image formation. On a screen coated with a special coating material instead of conventional high-priced LCD or LED displays, images for image formation can be displayed in various places. [0003] With the applicability of projector screens, there is an urgent need to provide for the mobility of the screen, the variety of sizes, the ease of disposal, and the ease of forming a screen co...
