Abstract

The invention relates to the field of projection curtains, and in particular relates to a diffuse reflection environment-friendly projection curtain coating and a manufacturing method thereof. The diffuse reflection environment-friendly projection curtain coating is prepared from the following raw materials: water-based resin, an additive, filler, a cross-linking agent, a leveling agent, an antifoaming agent and the balance of deionized water. In the diffuse reflection environment-friendly projection curtain coating and the preparation method thereof, the prepared water-based coating has excellent metal texture and metallic luster, excellent gloss and color retention, good impact resistance and wear resistance and scratch resistance, and has excellent acid resistance, alkali resistance, resistance to various chemicals and salt spray resistance, high hardness and good adhesion; the water-based resin is environmentally friendly, does not contain toxic chemical substances, is opposite to solvent type products in flammability, is a water-based product that is nonflammable and resistant to fire, and thus fire disasters are effectively reduced; polytetrafluoroethylene is resistant to high temperature and corrosion, has excellent electrical insulating property, aging resistance, low water absorption, excellent self-lubricating property and extremely high diffuse reflection, and the highest diffuse reflection rate can reach 99%.

Description

technical field [0001] The invention relates to the field of projection screens, in particular to a diffuse reflection environmental protection projection screen coating and a manufacturing method thereof. Background technique [0002] At present, projection technology is used in mobile small business presentations, multimedia conference rooms, classrooms, stadiums, churches, commercial venues, large auditoriums, virtual displays, and even large screens as large as movie theaters. Simply put, projection technology is the The light emitted by the projector is projected onto the projection screen, forming an image on the projection screen, and then the light is reflected to the human eyes. If the projection screen is properly matched with the projector, high-quality projection effects can be obtained. The projection screen can generally be divided into two types: Reflective type and transmissive type; reflective type is used for front projection, and transmissive type is used ...
