Problems solved by technology

[0002] With the rapid development of LED momentum, various companies are investing more in the R&D and manufacturing of LEDs. The necessary material for LED products to replace traditional lighting is lampshades. Because LEDs are assembled from multiple electric light sources, they need to disperse light. In order 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 paint on the bulb or glass. A lot of useful light is sacrificed

Embodiment 1

[0017] Mix 22kg of ethanol, 2kg of silicone light diffusing agent, 2kg of water, 2kg of alumina, 37kg of kaolin, and 28kg of acrylic resin in sequence, stir for 30 minutes, then add 0.3kg of HW5000 leveling agent, 0.5kg of HW-241 defoamer, and then grind , filter to obtain water-based paint, and put it in buckets for later use.

[0018] The water-based paint prepared in this embodiment was sprayed onto the surface of the LED bulb shell and the LED lamp tube shell, and then was blown with hot air to make it qualitative, and then baked at a temperature of 150°C for 20 minutes.

[0019] Using the water-based paint prepared in this embodiment, the light transmittance of the LED bulb shell and the LED lamp tube shell is as high as 95%.

Embodiment 2

[0021] Mix 30kg of ethanol, 4kg of silicone light diffusing agent, 6kg of water, 5kg of alumina, 45kg of kaolin, and 35kg of acrylic resin in sequence, stir for 30 minutes, then add 0.6kg of BYK-380N leveling agent, 1kg of SQ701 defoamer, and then grind, Filter to obtain water-based paint, and put it in buckets for later use.

[0022] The water-based paint prepared in this example was suction-coated on the surface of the LED bulb shell and the LED lamp tube shell, and then was blown with hot air to make it qualitative, and then baked at a temperature of 150° C. for 30 minutes.

[0023] Using the water-based paint prepared in this embodiment, the light transmittance of the LED bulb shell and the LED lamp tube shell is as high as 95%.

Embodiment 3

[0025] Mix 22kg of ethanol, 2kg of silicone light diffusing agent, 2kg of water, 2kg of alumina, 37kg of kaolin, and 28kg of acrylic resin in sequence, stir for 30 minutes, then add 0.3kg of HW5000 leveling agent and 0.5kg of SQ821 defoamer, then grind and filter , to obtain the water-based paint, and put it in buckets for later use.

[0026] The water-based paint prepared in this embodiment was sprayed onto the surface of the LED bulb shell and the LED lamp tube shell, and then was blown with hot air to make it qualitative, and then baked at a temperature of 150°C for 20 minutes.

[0027] Using the water-based paint prepared in this embodiment, the light transmittance of the LED bulb shell and the LED lamp tube shell is as high as 95%.

Abstract

The invention discloses water-based paint and a preparation method thereof. The formula of the water-based paint disclosed by the invention comprises the following ingredients in percentage by mass on the basis that the total mass percentage is 100%: 28-35% of acrylic resin, 37-45% of dyeing agent, 2-6% of alumina, 2-4% of light diffusion agent, 22-30% of ethanol, 0.8-1.6% of adjuvant and 2-6% of water. According to the water-based paint disclosed by the invention, LED (Light Emitting Diode) lamp bulbs or LED lamp tubes can achieve a very good light dispersion effect, and the light transmittance is increased and reaches up to 95%, so that the total light efficiency of products is increased; according to the preparation method, the combination of photoelectric technologies and the traditional coating industries is emphasized, so that energy sources are saved effectively; meanwhile, compared with the traditional oil-based paint, the water-based paint disclosed by the invention is more environmental-friendly and safer, is the main force for the development of LED traditional lighting in the future, and has broad application prospects.

Description

Technical field: [0001] The invention relates to a paint, in particular to a water-based paint and a preparation method thereof. Background technique: [0002] With the rapid development of LED momentum, various companies are investing more in the R&D and manufacturing of LEDs. The necessary material for LED products to replace traditional lighting is lampshades. Because LEDs are assembled from multiple electric light sources, they need to disperse light. In order 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 paint on the bulb or glass. A lot of useful light is sacrificed. Invention content: [0003] The object of the present invention is to provide an environmentally friendly, safe and efficient water-based paint and a preparation method thereof that can improve the light transmittance and light diffusion effect of LED bu...
