Description

DETAILED DESCRIPTION OF THE INVENTION The present invention relates to a light-scattering reflective resin composition which has good stability and is freely moldable. For details, regarding light-diffusing reflective resin, resin base material 100? For H<, 0.1 part of glitter
100 parts to maintain a stable light-diffusing pattern,
This invention relates to a moldable resin composition.

Light-scattering reflective resin compositions have conventionally used glass beads, metal powder, and nocturnal substances as light-reflecting substances, and have been used for traffic-related, architectural-related, etc., signs, markings, etc. at night and in the dark. For example, in a resin composition that uses glass beads such as white lines in road markings, only the glass beads exposed on the surface effectively receive and reflect the opposing light, while the glass beads buried in the resin receive and reflect the light. I don't object. Even if the resin wears out after use and the glass beads come to the surface, the glass beads are coated with an opaque resin and will not reflect light. In this case, the abrasiveness of the glass beads is not a problem, but the abrasiveness of the jM resin as a binder and the ability of the resin to hold the glass beads are problems. In reality, after applying -Ll, a sufficient reflection effect is exhibited, but the glass beads immediately separate from the surface and the light reflection effect disappears with time. Therefore, to maintain the reflective effect,
There is a need for constant maintenance.

When crushed metal powder is used as a reflective material, oxidation of the metal surface becomes a particular problem. υ[JAlso, metal powder uses its metallic luster to reflect light, but when it is oxidized, the metallic luster disappears and it cannot reflect light. Is the nature of metal powder buried? It is easily susceptible to oxidation. Therefore, when metal powder is used as a light-reflecting material, a resin used as a binder must be selected that does not oxidize or alter the quality of the metal powder, and the range of use and molding method are also limited.

In the light-diffuse-reflecting resin composition V according to the present invention, not only the glitter on the surface but also the glitter in the resin exhibits a light-diffuse reflection effect. Valid until exhausted. Therefore, if a resin with excellent %A abrasion resistance is used as a binder, the effective development of the light reflection effect will be dramatically improved.

On the other hand, the glitter used in Kizari 1 uses the same metal powder, but the metal surface is coated with a transparent resin that has excellent heat resistance, chemical resistance, and weather resistance, so it is different from the above-mentioned It is not subject to oxidation or deterioration, is extremely stable even in the air, and exhibits a semi-permanent light-reflecting effect.

7. Comparative study of the glitter of the present invention with other light-diffusing reflectors 7. Noctilucent substances have problems in weather resistance, in particular they are not resistant to ultraviolet rays, and their light-reflecting effects have a relatively short lifespan.

In addition, since nocturnal substances have chemically reactive groups, they do not react easily with resin binders, and if the binder is not selected, it will react with the resin and lose its light reflecting effect. receive.

In addition, light diffuser reflection using glass beads and nocturnal substances is possible.
When a light source is applied to a composition, the reflected light can be seen, but
If you shine light directly at a person, you won't be able to see the reflected light.

The light-diffuse-reflecting resin composition of the present invention has a characteristic that its light reflection property is diffuse reflection. reflects light in all directions. In other words, with conventional compositions, reflected light is only warped in the direction of the light source, but with the resin composite of the present invention, light is reflected by one angle not only in the direction of the light source, but also in the left, right, and opposite directions. emanate.

Conventional light-diffusion-reflecting resin compositions using glass beads, metal powder, and nocturnal substances have been used as a binder (for grease resistance).
In order to be subject to the great restriction of having to choose,
There are restrictions on processing such as molding.

Therefore, its uses are also limited.

The light-scattering reflective resin composition of the present invention is not subject to such limitations, and can be applied on-site and molded into sheets and cast molds. Of course, -C can also be applied as a paint. In other words, there are no restrictions on the usage,
It is characterized by the fact that it can be used in any way and can be shaped freely.

From the original 'JJ's Gritsuta Ichimonoke is already Gritsuta.
It is commercially available as.

(Product name: Glitter (sold by Toyo Metallizing) Products using it include cloth, etc.) There are sheets in the form of sheets, but the manufacturing methods include 70-layer processing or sprinkling on a resin binder. Because it is coated with grit, it has the disadvantage that it has poor holding power when it comes to grit, and it easily peels off. In order to solve this problem, the current situation is to use a resin cope jig from above the four rivers.

Since the light-diffusing reflective resin composition of the present invention has glitter mixed into the resin composition, there is no need to worry about the glitter coming off. It also has the advantage that it can be processed in one process.

Here, the light scattering properties of the present invention! The M fat composition has been described in terms of light reflection and processing, but of course it also has a wonderful aesthetic appearance and a fashionable design.

For example, if you use the light-diffusing reflective 4'iI pilgrimage composition of the present invention for mountain shoes, shoes, belts, bags, etc., it will not only be fashionable, but will also help prevent accidents while walking at night.) .

In other words, when wearing the above-mentioned product, the product emits diffusely reflected light due to the light of cars at night, making it difficult to identify the person. It has the advantage of being able to confirm.

As described above, the light-scattering reflective resin composition of the present invention is not only excellent industrially but also socially significant.

If necessary, dyes and pigments can be added to the IJIJ light-scattering reflective resin composition of the present invention. In this case face 1'l
It is preferable to add dyes since the light reflection effect may be disturbed. The use of teaching agents is also ρ■ ability. Next, the present invention will be explained with reference to Examples. (Hereinafter, "parts" in F unit means parts by weight.) Example 1 Gopasol 5H-108100 Glitter - 5 parts Iron array was heated in a 2500° heating furnace for 15 minutes and immersed in the above formulation for lθ seconds. Afterwards, the iron array was heated to 180C for 2 minutes. In this way, a coated iron array was created using the dipping method.

Example 2 Acryvet MF-001 100 parts Glitter 100 parts MF-001 was heated and melted at about 250°C to make glitter.
Add, mix, and pet again.

The pellets having the above composition were heated and melted at about 250°C to produce an acrylic plate.

Example 3 Epomate 828 100 parts Epomate 00
1 60 parts Glitter - 50 parts A brush holder was produced by casting the above mixture.

Example 4 Sofalex R-CI 100 parts Glitter-0,
5 parts of the formulation described above were applied to an umbrella.

Example 5 Varnish Gain 6040 100 copies Glitter - Part 2 The above formulation was applied to shoes and belts.

One of the effects of the light-diffusing reflective resin composition invented by Kido is that the binder resin is transparent or semi-transparent, and the glitter is stably diffused inside the binder, so separation from the surface due to wear etc. is not a problem. It is effective until the binder resin is used up.

Therefore, if a resin with excellent abrasion resistance is used as a binder, the effective period of the light reflection effect will be dramatically improved.

As in the above-mentioned embodiments, it has the feature of being able to be molded freely.
