Environment-friendly water-based self-luminous coating with good weather fastness

Abstract

The invention discloses an environment-friendly water-based self-luminous paint with good weather resistance, which is composed of the following raw materials: 10-50% of hydroxyl acrylic resin emulsion, 1-20% of light diffusing agent, 10-60% of long afterglow luminous powder, 0.1-5% of modified bentonite, 0.05-1% of water-based silicone defoamer, 0.05-1% of water-based silicone leveling agent, and 5-30% of isocyanate prepolymer. It has good adhesion and is suitable for the surface of metal, plastic, ceramics, wood, walls and other materials. It has the ability to absorb sunlight during the day and emits light naturally at night. It has high light transmittance, high luminous intensity, soft light and long afterglow time. The visual sensory effect is clear; the coating is sprayed on the surface of the material and has good weather resistance, and the service life is increased by more than 5 times.

Description

technical field [0001] The invention relates to a self-luminous material, in particular to an environment-friendly water-based self-luminous paint with good weather resistance. Background technique [0002] At present, self-luminous coatings are widely used in traffic signs, urban landscaping, etc. It sprays self-luminous paint on the surface of metal products, wood products, floors and other materials to form a self-luminous layer. When there is light, the self-luminous layer stores light in a short time to reach light energy saturation. When there is no light, the self-luminous layer stores light. The light can emit light by itself for more than 10 hours. However, the existing self-luminous coatings generally have the following deficiencies: the first is that the sprayed self-luminous logo coating has low light transmittance and weak luminous intensity, and people's nighttime visual sensory effect is not clear; the second is that the self-luminous display device is usuall...

Problems solved by technology

However, the existing self-luminous coatings generally have the following deficiencies: the first is that the sprayed self-luminous logo coating has low light transmittance and weak luminous intensity, and people's nighttime visual sensory effect is not clear; the second is that the self-luminous display device is usually placed outdoors In the harsh climate environment, after long-term wind, sun, rain and snow erosion, the self-luminous coating layer is easily aged, cracked and peeled off, which seriously reduces the service life of the self-luminous display device.
