骨4・・に/−ト部5を取り付けたものである。FIGS. 1 and 2 are diagrams showing an embodiment of the present invention, and in these figures, reference numeral 1 represents an umbrella. This umbrella 1 has the same structure as a conventionally commonly used Western umbrella (umbrella), and has a handle 3 formed on one side of an umbrella shaft 2, a large number of ribs 4 attached to the other side, and A /-t part 5 is attached to these main ribs 4.

ある。The main ribs 4 are each rotatably attached to one end or the umbrella shaft 2, and a support bone 6 is connected to the intermediate portion thereof. One end of the support rib 6 is rotatably attached to the main rib 4, and the other end is rotatably attached to a potter's wheel 7 which is slidably inserted onto the umbrella shaft 2.

てシート部5を閉じることができるものとなっている。The seat part 5 is approximately circular and is attached to the main rib 4 with a stone 8 formed at the opposite end of the handle 3 of the umbrella shaft 2 as the center, and is made of a sheet of cloth or synthetic resin. It is something. Then, with this configuration, umbrella 1
By sliding the potter's wheel 7 on the umbrella shaft 2, the main ribs 4 and 6 can be erected and the seat part 5 can be opened (and the main ribs 4 and 6 can be opened). ... can be folded to close the seat portion 5.

微粒酸化亜鉛を得るのである。Various methods can be adopted to produce such fine particles of zinc oxide, but for example, it can be produced based on the method for producing ultrafine zinc oxide previously proposed by the applicant (Japanese Patent Application No. 1-130422). be able to. In other words, in this method,
Hydrogen sulfide was passed through a mixed solution of zinc acid salt and ammonium acetate to remove soluble salts from the resulting precipitate, then the precipitate was dispersed in a non-aqueous solvent, and the mixture was heated in an autoclave at 250 to 400'C. The gas is removed by heating, and the resulting dry powder is then heat-treated at 500 to 800°C to obtain ultrafine zinc oxide particles.
なお、本発明では酸化亜鉛の粒径を0.1μπ以下にし
たか、粒子の9割が0005〜0.05μ屑であるのか
より好ましい。In the present invention, it is more preferable that the particle size of the zinc oxide be 0.1 μπ or less, or that 90% of the particles be 0005 to 0.05 μ debris.

ず、塗膜か脆くなってしまうからである。In such a paint made of zinc oxide, a binder, and a solvent, the amount of zinc oxide ultrafine particles is 5 to 9% of the solid content of the paint.
The content is 0% by weight, preferably 40 to 80% by weight. Here, the amount of zinc oxide ultrafine particles is 5% of the paint solids.
The reason why the amount of zinc oxide is less than 5% by weight is that the percentage of light that does not pass through zinc oxide increases and the blocking rate of ultraviolet rays decreases, whereas when the amount of zinc oxide exceeds 90% by weight This is because the amount of binder (binder) becomes relatively small, and the binder cannot fill the spaces between the zinc oxide particles, resulting in a brittle coating film.

It is said that In order to uniformly disperse the fine particles of zinc oxide in the binder, for example, a whole mill, an attritor, a sand grinder, a three-roll mill, a high-speed impeller mill, a jet mill, a paint mill, a homogenizer, an ultrasonic dispersion machine, etc. It is desirable to use sudo alone or in combination.

In this case, the thickness of the absorbent film 9 formed by applying the paint is set to be approximately 20 μm or less when spray coating, dip coating, brush coating, etc. are used, from the viewpoint of workability; In the case of offset printing or the like, the amount is about 1 to 5 μl. The absorbing film 9 formed in this way needs to be sufficiently transparent so that the patterns and designs of the sorting section 5 can be clearly seen, so the haze value of the film 9 is preferably 10 haze or less. , shi< are set to be 1 haze or less.

ことができる。In the umbrella 1 formed with such an ultraviolet absorbing film 9,
Since the ultraviolet absorbing film 9 is formed on the sorting part 5 without damaging the pattern or the tethers of the umbrella 1, the umbrella has no difference in appearance compared to a conventional umbrella. Moreover, since this absorption film 9 absorbs ultraviolet rays well, by applying it, it is possible to easily prevent the human body from being irradiated with ultraviolet rays.

れなかった。When we investigated the ultraviolet absorption rate of sheets for umbrellas, parasols, and beach umbrellas on which ultraviolet-absorbing films were formed, we found that all of them were able to block more than 90% of ultraviolet rays with a wavelength of 400 μl or less. No discoloration of the sheet was observed at all.

The ultraviolet absorbing film does not spoil the pattern or design of the umbrella at all (since it is formed on the sheet, there is no difference in appearance compared to conventional umbrellas). Because it absorbs UV rays well, using this umbrella can easily prevent the human body from being irradiated with ultraviolet rays, thereby easily preventing the development of skin cancer.
