JP2008168275A - Surface coating by which underlying coating omnidirectionally reflects omnidirectional incident light - Google Patents

Abstract

<P>PROBLEM TO BE SOLVED: To provide surface coating by which an underlying coating omnidirectionally reflects omnidirectional incident light, which improves a difficulty in seeing a coated surface due to directions of night lighting for road signs or the intensity of illumination caused by a diffuse reflection of transparent and colorless crystal powders mixed in transparent and colorless paint, or a difficulty in seeing a coated surface due to the reflection from a water surface upon rainfall. <P>SOLUTION: Provided are shining coating surface paint prepared by mixing the transparent and colorless crystal powders 8 such as glass or acrylic in a transparent and colorless coating agent, and the surface coating 5 using the same. The use of a diffuse reflection characteristic of the crystal powder facilitates the visualization of the underlying coating. <P>COPYRIGHT: (C)2008,JPO&INPIT

Description

Omni-directional reflective paint

None.

Problems to be Solved by the Invention

Road sign painting etc. (1) Direction of night illumination, difficulty in viewing the painted surface due to the intensity of illumination, (2) difficulty in viewing the painted surface due to reflection of the water surface during rainfall.

Steps to solve the problem

In the case of (1) above, most of the reflected light from the road sign painted surface of the car lighting flows forward, the reflected light is limited to the unevenness of the painted surface, and the amount of light reflected on the driver's seat is extremely high Few. (See FIG. 1).
In the case of the above (2), since the surface of water accumulated on the coating surface directly reflects most of the light from the outside, there is little light reaching the coating surface and there is almost no reflected light. (See FIG. 2).
In order to improve these problems, a powder obtained by pulverizing a colorless and transparent crystal is applied to the coating surface, and the reflected light of the ground coating surface entering the field of view is diffused and dramatically increased (see FIG. 3).

The invention's effect

It will greatly improve the visibility of road signs, etc. at night, and the visibility during rainfall.
This special paint is omnidirectional, unlike fluorescent paint, so it may be used instead of fluorescent paint.

BEST MODE FOR CARRYING OUT THE INVENTION

  Surface coating of signs such as lanes and pedestrian crossings on the road

(1) A paint obtained by mixing a colorless and transparent coating solvent with a powder (100 mesh-2 mm diameter) obtained by pulverizing colorless and transparent crystals is applied to the surface of the road sign coating.
(2) Apply a colorless and transparent coating solvent to the road sign painted surface. A powder (0.5-2 millimeter diameter) obtained by pulverizing colorless and transparent crystals is sprayed on the surface as thinly as possible. Further, the surface is coated with a colorless and transparent coating solvent to finish the surface.

It may be used in places and areas where an omnidirectional coating is required.

It shows that most of the headlights of automobiles flow forward. It shows that most of the headlights of automobiles are reflected on the water surface and flow forward. The lighting of the headlight of a car shows that it is diffusely reflected by the colorless and transparent crystalline powder applied to the road sign surface and partially reflected in the driver's field of view.
