Advantages and features of the present invention, and methods for achieving them will be clarified with reference to embodiments described below in detail together with the accompanying drawings.

In the following, the proposed high-efficiency reflective coating and its construction method will be described using drawings and examples.

The reflective coatings of the present invention include glass beads, urethane resins, and pigments.

The glass bead is a material having a retroreflective ability, and the glass beads of the round lens function as a lens to concentrate the focus on the light coming from the outside to make the retroreflection due to the refractive index more strongly and clearly diffuse reflection, thereby ensuring clear visibility. As possible.

The urethane resin serves as a base for the paint.

The pigment is used to express the color by purpose to the user, and various design changes are possible.

Hereinafter, the method for manufacturing the reflective coating will be described in detail.

1 is a flow chart showing a method of manufacturing a reflective coating according to an embodiment of the present invention.

First, in the first step A1 (A1), the glass beads are homogenized. More specifically, the size of the glass beads is uniformized, and impurities are removed.

When the particle size of the glass beads is non-uniform, it is important to make the size uniform since the desired refractive value does not come out, such as the large size interfering with the refraction of the small size to cause diffuse reflection.

It is preferable that the particles of the glass bead are 80-100 µm during the homogenization. When the glass bead particles are less than 80 μm, it is difficult to construct, use, and store, and when 100 μm, uniform mixing with the paint may be difficult.

In addition, it is preferable to use the high-refractive beads having a refractive index of 1.92.

Next, in the second step A2 (A2), a mixture is prepared by mixing the glass beads and a urethane resin. Specifically, the glass beads and the urethane resin are mixed in order to prepare in the form of a paint.

The urethane resin is mixed with a suitable base coating capable of smooth mixing with the glass beads. The urethane resin is generally white color.

In addition, the mixing ratio of the glass beads and urethane resin is preferably mixed with 0.8 to 1 part by weight of urethane resin with respect to 1 part by weight of glass beads. When the urethane resin is mixed in an amount of less than 0.8 parts by weight with respect to 1 part by weight of the glass beads, a problem such as deterioration of paint spreadability occurs, and when it exceeds 1 part by weight, sufficient reflection effect by the glass beads may not be exhibited. have.

Next, in step A3 (A3), a pigment is added to the mixture and mixed to prepare a reflective coating. Specifically, the pigment is added to the mixture of the glass beads and the urethane resin according to the user's purpose to complete the preparation of the reflective coating.

Hereinafter, the reflective coating method will be described in detail.

The urethane resin is white, and it is preferable to apply the urethane layer resin so that a thickness of 20 μm is formed from the surface of the object to be coated.

In addition, the urethane resin can be replaced with a white-based paint.

In addition, a curing agent may be included when the urethane resin is applied. The curing agent is preferably mixed with 1 part by weight of the curing agent with respect to 6 parts by weight of the urethane resin in consideration of strength and bonding degree.

Next, in step B2 (B2), a primary heat treatment is performed on the object to which the urethane resin is applied. Specifically, the primer urethane layer 2, which is the object to which the urethane resin is applied, is heat treated at 100° C. for 1 hour.

The silver coating layer 3 is preferably applied so that a thickness of 20㎛ is formed.

In addition, when applying the silver (silver) color coating, a silver coating may include a curing agent. It is preferable to mix 1 part by weight of the curing agent with respect to 3 parts by weight of the silver coating in consideration of the strength and the degree of bonding.

Next, in step B4 (B4), secondary heat treatment is performed on the object to which the silver coating is applied. Specifically, the silver coating layer 3, which is the object to which the silver coating is applied, is heat-treated at 100° C. for 1 hour.

Next, in step B5 (B5), a reflective coating is applied to the object to which the secondary heat treatment has been performed. Specifically, a reflective coating prepared by mixing a glass bead, a urethane resin, and a dye is coated on the upper surface of the silver coating layer 3, which is the coating object subjected to the second heat treatment, to constitute the reflective coating layer 4.

The reflective coating layer 4 is preferably applied so that a thickness of 30㎛ is formed.

In addition, a curing agent may be included when the reflective coating is applied. It is preferable to mix 1 part by weight of the curing agent with respect to 3 parts by weight of the reflective coating in consideration of the strength and the degree of bonding.

Next, in step B6 (B6), a third heat treatment is performed on the object to which the reflective coating is applied. Specifically, the reflective coating layer 4, which is the object to which the reflective coating is applied, is heat treated at 100° C. for 1 hour.

Next, in step B7 (B7), a coating is applied to the object to which the third heat treatment is applied using a coating agent. Specifically, the coating layer 5 is formed by performing a transparent coating using a coating agent on the upper surface of the reflective coating layer 4, which is an object to be subjected to the third heat treatment.

Unlike the application by the existing construction method, the use period of the glass beads can be increased by flattening the construction surface as shown in FIGS. 3 to 4 and protecting the glass beads through the coating layer 5.

The coating layer 5 is preferably applied to form a 10㎛ thickness.

In addition, when applying the coating agent may include a curing agent. It is preferable to mix 1 part by weight of the curing agent with respect to 2 parts by weight of the coating agent in consideration of strength and bonding degree.
