を形成したものである。As a method for dealing with this, a so-called shatterproof type fluorescent lamp is known, in which the outer surface of a glass tube is covered with a transparent tube made of a polymer resin such as polyester resin. This is a method in which a glass tube is covered with a heat-shrinkable polyester resin tube, and then the tube is heat-treated to form a transparent polymer resin coating on the outer surface of the glass tube.
発明が解決しようとする課題
従来の飛散防止形蛍光灯では耐候性、膜強度等を考慮し

不可欠で、そのために飛散防止形蛍光灯は一般蛍光灯に
比べ極めて高価なものになってしまうという問題があっ
た。However, this tube is extremely expensive due to the difficulty of tube processing, and the process of manually covering the completed fluorescent lamp with the tube is extremely difficult to work with.For this reason, shatterproof fluorescent lamps are There was a problem in that they were extremely expensive compared to general fluorescent lamps.
本発明は上記の従来の問題点を解決するためになされた
ものであり、従来に比べ被膜形成が容易で、かつ作業性

る。The present invention has been made in order to solve the above-mentioned conventional problems, and provides a method for manufacturing a shatterproof fluorescent lamp, which makes it easier to form a coating and has better workability than the conventional method.
課題を解決するだめの手段
この目的を達成するために、本発明の飛散防止形蛍光灯
の製造方法は、ガラス管の外面に架橋構造をもつウレタ
ンエラストマーを水に分散させたポリウレタン水分散体
を主成分とする塗布液を用いて透明な被膜を形成する構
成を有している。Means for Solving the Problem In order to achieve this object, the method for manufacturing a shatterproof fluorescent lamp of the present invention uses a polyurethane water dispersion in which a urethane elastomer having a crosslinked structure is dispersed in water on the outer surface of a glass tube. It has a structure in which a transparent film is formed using a coating liquid as the main component.

含有しないため、環境汚染や火災の危険性がないうえに
無黄変の強靭な被膜を形成する新規な被膜材料である。According to the present invention, by forming a transparent polyurethane resin coating on the outer surface of a glass tube, a coating device for preventing scattering can be applied efficiently, quickly, and in large quantities to the outer surface of the glass tube. Since the polyurethane aqueous dispersion does not contain organic solvents, it is a new coating material that poses no risk of environmental pollution or fire, and forms a strong coating that does not yellow.

ても被膜は全く破損しなかった。Example Polyurethane aqueous dispersion (manufactured by Dai-Kogyo Seiyaku Co., Ltd.: Superflex-107) A straight tube type 40 watt fluorescent lamp held horizontally was immersed in an IF 500 gr solution.
It was dried with hot air at 5 m/sec at 5 m/sec to form a transparent film made of polyurethane resin on the outer surface of the glass tube. Using the thus obtained fluorescent lamp, the following drop strength test was conducted. First, keep the fluorescent light horizontal,
When this was allowed to fall naturally from a height of 3 m, the glass tube was damaged, but the coating remained intact, and the glass pieces were firmly attached to the coating, so the glass pieces were protected by the coating. There was nothing that could be scattered. Next, as a shock test, 20
Even when a 0gr steel ball was exposed to a fluorescent lamp at an angle of 30 degrees from the vertical line, the coating was not damaged at all.
