Description
Technical Field
The invention relates to the field of coatings, in particular to a reflective coating and a preparation method and application thereof.
Background
The reflecting material can utilize the irradiation of the car lamp and the reflection of light rays to 'light' the front according to a retro-reflection principle, so that the distance of a driver for finding a front object is increased, and the driver can take corresponding safety measures within more sufficient time. Compared with other various road traffic safety measures and various cost for reducing the damage of road traffic accidents, the application of the retro-reflection technology is undoubtedly a low-cost and effective solution. In a certain sense, the application of the retroreflective material is a more active safety precaution measure, and compared with measures aiming at reducing the damage degree after an accident, such as guardrail protection, the retroreflective material has higher safety value and can reflect the care of life.
The reflective materials are all prepared from a core raw material, namely reflective powder, wherein the reflective powder is prepared from a glass microsphere powder material, namely: ND is more than or equal to 1.90, ND is more than or equal to 1.93, ND is more than or equal to 2.2, the specification can be provided from 100 meshes to 800 meshes in a grading way, and the color is selected from gray and white. FIG. 1 is a schematic view of the reflection principle of reflective glass beads; as can be seen from fig. 1, the principle of light reflection of the light reflecting glass beads is that when light is irradiated on the surface of the beads, the light is condensed on a special reflecting layer at the focal point of the beads due to the high refractive action of the beads, and the reflecting layer re-reflects the light to the vicinity of the light source through the transparent beads, so that very bright reflected light can be seen at the light source. According to the calculation of a complex optical formula, when the refractive index of the micro-bead is more than 1.9, a good retro-reflection effect can be formed.
At present, two main ways for achieving the reflecting effect are reflective coating and reflective film, the reflective film is mainly applied to a road traffic sign and a motor vehicle, and the reflective coating is mainly applied to cast-in-place concrete or asphalt pavement. Fig. 2 is a schematic view of the reflection principle of the reflective paint. Fig. 3 is a schematic view of the reflection principle of the reflective film. As can be seen from fig. 2 and 3, the reflective film mainly uses an adhesive layer to bond the reflective film and the object, so that the object is required to have a smooth and flat surface, and as the outdoor service life increases, the reflective film in the outdoor environment may also be at risk of degumming, and the production technology of the reflective film is relatively complex. The production technology of the reflective coating is simpler than that of a reflective film, and the existing reflective coating is composed of reflective glass beads, pavement bonding resin, an anti-settling agent, an anti-aging agent and a solvent. Because the reflective powder has coarse particle size and large specific gravity, the surface of a prepared paint film is very rough, has gray or white color and cannot present beautiful color, the existing reflective paint is generally applied to the field with low requirements on the appearance and touch of the paint film, and the construction mode is mostly brush coating and powder scattering mode, such as road signs and traffic warning boards.
However, with the increasing outdoor sports of people, the frequency of use of outdoor intelligent sports electronic products is also increasing, for example, intelligent products such as sports watch bracelets, head-wearing sports bluetooth headsets and balance cars are more and more important, because most young people who are in the city at present have the habit of doing sports and building up bodies at night, and therefore it is important that the intelligent electronic products have a light reflection effect to ensure the safety of the consumer during the night sports. Most of traditional reflective paints are coated singly, and the reflective powder is half exposed on the surface of a paint film by adopting a brushing or powder scattering construction mode, so that the paint film has single color, extremely rough and uneven hand feeling and appearance, and cannot be used on outdoor electronic products.
Therefore, there is a need for a reflective coating that has beautiful metal color and silky skin-friendly hand.

The aluminum powder primer disclosed by the invention can further enhance the light reflecting effect, and can present various colors by matching with metal primers with different colors. The refractive index of the reflective powder for the reflective layer is 1.93, light just focuses on the bottom interface of the reflective powder, and the retro-reflection of the light at the interface is further enhanced due to the aluminum powder contained in the metallic colored paint, so that the improvement of the reflective effect is enhanced. And the reflecting powder used by the product is white, so the covering property to the color is not obvious to the gray, and color paste can be added into the primer layer to present different colors. Skin-friendly smooth feeling and permanent hydrophobic, oleophobic and dirt-resistant effect; the main resin of the hand feeling finish paint layer is polycarbonate diol, the hydroxy acrylic resin is auxiliary resin, the molecular weight of the polycarbonate diol is 1000-3000, both ends of the polycarbonate diol are provided with OH hydroxyl, and the polycarbonate diol reacts with an isocyanate curing agent to generate polyurethane under the action of high-temperature baking and a catalyst. The polycarbonate diol may form a soft part of the final polyurethane coating, thus providing the product with a skin-friendly hand. The hand feeling finish paint layer is also added with the organosilicon surface auxiliary agent containing hydroxyl, and because of the modification of the auxiliary agent siloxane, a paint film has the performance of easy cleaning, the hydrophobicity and the oil increasing performance of the paint are also increased, and the smoothness of the surface of the paint is improved; in addition, the strong interfacial activity of the auxiliary agent can cause the auxiliary agent to spontaneously migrate to the surface of the coating, and in addition, the auxiliary agent also contains OH functional groups which can be subjected to a crosslinking reaction with an isocyanate curing agent, and the functional groups after the reaction are fixed on the surface, so that the hydrophobic and oleophobic performances brought by the auxiliary agent have long-term performance. The special flatting mode feeling finish paint effect does not use the conventional matte powder, and uses polyethylene wax slurry and organic silicon resin powder, so that the silky feeling of the paint film surface is further enhanced. The polyethylene wax slurry is small in particle size and high in light transmittance, the organic silicon resin powder is spherical particles, the polymethyl semi-siloxane is used as the component, the organic silicon resin powder has a three-dimensional network structure, and the organic silicon resin powder is suspended on a paint film, so that the extinction effect is achieved, and the paint film is endowed with a silky hand feeling. Compared with the conventional matte powder extinction, the extinction mode has much smaller influence on the reflection of light.
