Embodiment 1

[0025] Embodiment 1 A novel water-based luminescent coating, the preparation method is as follows:

[0026] (1) Add acrylic acid emulsion, styrene-butadiene emulsion, anti-sedimentation agent, and wetting and dispersing agent into the stainless steel high-speed stirrer according to the proportioning in Table 1, and stir it evenly with a rotating speed of 300 rpm;

[0027] (2) Slowly add luminescent powder into the agitator at a stirring rate of 300 rpm, and stir at a rotating speed of 2000 rpm for 30 minutes to make it evenly stirred;

[0028] (3) Then reduce the rotation speed to 300 rpm, add defoamer, film-forming aid and filler in turn, after adding, continue to stir for 30 minutes until completely mixed, and finally add deionized water.

[0029] Examples 2-4 According to the method of Example 1, combined with the ratio of raw materials in Table 1, the corresponding water-based luminescent paint was prepared.

[0030] The luminescent powder used in Examples 1-4 was purchas...

Abstract

The invention discloses a novel waterborne luminescent coating and a preparation method thereof. The coating comprises acrylic emulsion, styrene-butadiene emulsion, an anti-settling agent, a wetting dispersant, a defoaming agent, a coalescing agent, deionized water, luminescent powder and a filler. The preparation process comprises the following steps of: firstly, adding the acrylic emulsion, styrene-butadiene emulsion, anti-settling agent and wetting dispersant into a container, and uniformly stirring the materials at a rotating speed of 300 revolutions per minute; then, slowly adding the luminescent powder at the same stirring rate, and carrying out stirring at a rotating speed of 2000rpm until the materials are uniformly mixed; and finally, reducing the rotating speed to 300rpm, addingthe defoaming agent, coalescing agent and filler in sequence, then fully stirring the materials until the materials are completely and uniformly mixed, and finally adjusting the viscosity and the solid content with deionized water. According to the novel waterborne luminescent coating provided by the invention, solid glass micro-spheres are used as a filler, so that the luminous efficiency and afterglow time of the coating are greatly improved, and the service time of the paint film of the coating is prolonged.

Description

technical field [0001] The invention relates to the field of coatings, in particular to a novel water-based luminous coating and a preparation method thereof. Background technique [0002] Luminescent paint refers to a type of paint that can absorb and store light energy under visible light such as sunlight or lamplight, and then slowly release the absorbed energy in the form of visible light in a dark place. Due to its continuous luminous time of more than 8 hours and the characteristics of no radiation, it is expected to be used in low-level lighting of park roads at night, urban road turning signs, and community escape stairs, etc., which can improve night driving safety and beautify the urban environment. [0003] At present, there are two main types of energy storage luminescent materials used in the coating industry, one is copper-activated zinc sulfide-based luminescent materials; the other is rare earth-activated alkaline earth metal aluminate luminescent materials. ...
