Problems solved by technology

[0002] With the rapid development of LED momentum, many companies are investing more in the R&D and manufacturing of LEDs. The necessary material to replace traditional lighting LED products is the lampshade. Because LEDs are gathered from multiple electric light sources, they need to disperse the light. To achieve the lighting effect, most of the current LED lighting products, especially bulb lamps and T8 straight tube lamp shells, are often used for LED products by applying a layer of traditional water-based paint on the bulb or glass, but now Some water-based paints have a light transmittance of about 90%, which often sacrifices a lot of useful light, and the greater the light transmittance of the coating, the worse its yellowing resistance, and yellowing will occur after a long time of use. Affect the ornamental value of lamps and lanterns

Abstract

The invention provides water paint with high light transmission. The water paint is prepared from, by mass, 35-45% of acrylic resin / polyurethane, 35-40% of powder filler, 0.9-1.5% of an additive and the balance water; the powder filler contains spherical organosilicon, and the dosage of the spherical organosilicon accounts for 5-15% of the total mass of the water paint. According to the water paint with the high light transmission, the powder filler contains the spherical organosilicon, under the action of a dispersing agent / polyurethane, the powder filler is well dispersed among all components of the water paint, and the light transmittance is integrally improved and reaches 93% or above.
