外線による劣化を防止するための塗料ないし表面保護膜
に混入するのに適した紫外線吸収フレーク状ガラスに間
する。[Detailed Description of the Invention] [Field of Application of the Invention] The present invention is applicable to cosmetics for preventing sunburn, plastic films with an insect damage prevention effect used in greenhouse horticulture, and paints or surfaces for preventing deterioration caused by ultraviolet rays. A UV-absorbing glass flake suitable for inclusion in a protective film is used.
［従来技術］
近年、酸化チタンが表面にコーティングされた微細な薄
片状雲母を含む乳液は、酸化チタンによる紫外線防止効
果の外に、真珠光沢と様々な干渉色を有するため、日焼
は防止のための化粧品として用いられるようになった。[Prior art] In recent years, emulsion containing fine flaky mica whose surface is coated with titanium oxide has not only the effect of preventing ultraviolet rays due to the titanium oxide, but also has pearlescent luster and various interference colors, making it difficult to prevent sunburn. It began to be used as a cosmetic product.
上記化粧品に於て、乳剤ないしはクリーム状物質に混入
された、表面に酸化チタンがコーティングされた薄片状
の雲母微粒によって、紫外線防止効果が得られる。In the above-mentioned cosmetics, ultraviolet rays can be prevented by the flaky mica particles whose surfaces are coated with titanium oxide, which are mixed into the emulsion or cream-like substance.
しかし、これらの酸化チタンの結晶形がアナターゼであ
る場合は、光触媒効果による皮膚に対する強力な酸化作
用があり、安全衛生上の問題点が指撞されるようになっ
た。However, when the crystal form of titanium oxide is anatase, it has a strong oxidizing effect on the skin due to the photocatalytic effect, and safety and health problems have been raised.
また、酸化チタンにスズ化合物を添加して、通常は６５
０’Ｃ以上、通常は、９００°Ｃ以上の高温で焼成を行
うことにより、上記酸化チタンの結晶形を比較的光触媒
作用の小さいルチルに転移させることができる。この場

然として存在していることの外に、雲母が５００°Ｃ以
上の高温では水を少しずつ放出して分解することのため
に、扉片状の形態がくずれ、製品の光沢ないしは滑らか
さが損なわれるという不都合があった。In addition, a tin compound is added to titanium oxide, usually 65
By performing the firing at a high temperature of 0'C or higher, usually 900C or higher, the crystal form of the titanium oxide can be transferred to rutile, which has a relatively low photocatalytic effect. In this case, in addition to the fact that there are still doubts about the long-term safety of tin on the skin, mica decomposes at high temperatures above 500°C, slowly releasing water, so This has the disadvantage that the shape of the product is distorted and the gloss or smoothness of the product is impaired.
また、この様な化粧品に、赤、青、黄等の色調を与えよ
うとするとき、有機質着色料を上記の雲母表面に均一に
コーティングすることが困難でありた。Furthermore, when attempting to impart red, blue, yellow, or other color tones to such cosmetics, it has been difficult to uniformly coat the mica surface with an organic coloring agent.
更に、上記着色料の皮膚に対する安全性も問題になる。Furthermore, the safety of the above-mentioned colorants on the skin is also a problem.
また、施設園芸においては、害虫の行動性が近紫外光が

の不都合があった。また、ベンゾフェノン系、ヘンシト
リアゾール系、サリチル酸エステル系およびアクリロニ
トリル系の紫外線吸収剤をフィルム中に添加している。Furthermore, in greenhouse horticulture, plastic films that block ultraviolet light have come to be used, taking advantage of the fact that the behavior of pests is significantly reduced when near-ultraviolet light is blocked. In this case, an ultraviolet absorbing substance such as ZnO is usually mixed into the plastic film, but it is difficult to mix uniformly and there are disadvantages such as a decrease in the strength of the film. Additionally, benzophenone-based, hensitriazole-based, salicylic acid ester-based, and acrylonitrile-based ultraviolet absorbers are added to the film.
この場合、透明性は保たれるが、紫外線の吸収と共に上
記吸収剤が分解して行くため、長期間の耐光性に問題が
ある。In this case, although transparency is maintained, there is a problem in long-term light resistance because the absorbent decomposes as the ultraviolet rays are absorbed.
［発明が解決しようとする問題点］
本発明は、従来の日焼は防止化粧品での雲母チタンの上
述の問題点、即ち、アナターゼによる光酸化作用、ある
いはルチル化におけるスズの使用による安全性の疑問、

ことを目的とする。[Problems to be Solved by the Invention] The present invention solves the above-mentioned problems of mica titanium in conventional sunburn prevention cosmetics, namely, the photo-oxidation effect due to anatase or the safety due to the use of tin in rutilization. doubts,
The purpose is to solve problems such as decomposition of mica due to high temperature firing.
更に、紫外線防止フィルムのための均一混合が容易で且

＝０．４−２．２である。従来のフレーク状ガラスでは
３００ｎｍの光に対して厚、７７１μｍ（光通過長さ）
あたり５パーセント以下の吸収率を有するが、本発明の
ものではその吸収率は２０パ一セント以上に達する。Oxides of Ni, Ta, Hf, Zr, and Cr are known, and ultraviolet absorbing glasses containing them are well known. Among these metal oxides, those with a large absorption coefficient for ultraviolet rays and small absorption of visible rays are:
Examples include oxides of Fe, Ce, and Tj. Especially FeM
In the combination of a oxide and a Ce oxide, ultraviolet absorption is performed more effectively because the Ce oxide oxidizes Fe in the Fe@ oxide to form Fe2O3. The preferred ratio of CeO2 and Fe2O3 is expressed by weight: CeO2/Fe2o3
=0.4-2.2. Conventional flake glass has a thickness of 771 μm (light passage length) for 300 nm light.
However, in the case of the present invention, the absorption rate reaches 20 percent or more.

色、灰−色などの着色剤を添加することが出来る。[Function] The ultraviolet absorbing flake glass that meets the present invention has excellent chemical durability such as chemical resistance and water resistance, so it not only does not release harmful ingredients to the skin but also resists sunlight. When exposed, it does not have a photo-oxidation effect like conventional titanium mica, so it can be used as a raw material for sunscreen cosmetics and is safe for the skin. Taking advantage of this feature,
Coloring agents such as red, pink, blue, brown, and gray can be added to the components of the glass flakes.

するとともに、太陽光の差し込む隙間を見つけて逃げ去
ってしまうので、昆虫による被害が激減する。Sunburn is caused by ultraviolet rays with a wavelength of 280-320 nm hitting the skin, so as seen in the examples below, the flaky glass of the present invention absorbs these ultraviolet rays and therefore does not prevent sunburn. effective. In addition, the ultraviolet ray prevention plastic film mixed with glass flakes according to the present invention absorbs near ultraviolet rays of 300-400 nm, so if this plastic film is used as a windshield material for greenhouse horticulture, insects will be
Because they have visibility in the nanometer wavelength range, their activity is significantly reduced, and they find gaps where sunlight can penetrate and escape, dramatically reducing damage caused by insects.

フレーク状ガラスは従来の雲母チタンに比べて、アスペ
クト比が大きいため、乳液などの媒体に添加して皮膚な
どに塗布する場合、比較的小量で被覆効果が得られる。Glass flakes consistent with the present invention have a thickness of 1 to 6 microns, preferably 1 to 3 microns, and a particle size of 24 mesh (710 microns) with preferably less than 20 percent remaining, typically 48 mesh. (29
7 microns) with a penetration rate of 80 percent or more and an average particle size of several tens of microns. Since the ultraviolet absorbing flaky glass of the present invention has a larger aspect ratio than conventional titanium mica, when it is added to a medium such as an emulsion and applied to the skin, a covering effect can be obtained with a relatively small amount.
更に、ガラスの性質から表面の平滑性に優れているため
