Adhere K to the glass tube and the fluorescent lamp, M and the fluorescent lamp using this composition. At the time of manufacture, the fluorescent lamp is manufactured by suspending the fluorescent skull in a solution of a nitrate ore binder dissolved in an organic solvent such as butyl acetate, in order to attach the phosphor to the solid On the inner surface of the glass tube, add divalent auronic acid borate with a composition of B a 0 · C a 0 • Bϊ〇3, and mix it thoroughly to form a phosphor coating solution, which is applied to the inner wall of the glass tube and then dried , Use baking to decompose and remove the adhesive to form a fluorescent film.

320624 A7. B7 V. Description of the invention (2) After the fluorescent film is formed * The ring-shaped fluorescent lamp with a golden tube has a problem that the fluorescent film is more easily peeled off. In addition, when low-melting-point glass is used as the adhesive, the fluorescent film is adhered to the glass tube due to fusion. • Although it has sufficient adhesion, it has poor water resistance. Therefore, another binder is proposed, which is a borate of at least one divalent metal in Mg, Ca, Sr, Ba, Zn, at least one of AI2〇3, Si02 and Sb 2 〇3, and Y and Burmese The vaporization of at least one element in the element (Ln) is intended to make the low-melting point glass of the binder difficult to dissolve in water (refer to No. 3-1 7 7 8). However, even in this method, the water resistance is not sufficient, and if crushed into fine particles and suspended in water, the fine particles have a problem of dissolution in water. Therefore, there is an urgent need to develop a binder, when the phosphor coating liquid is applied to the glass tube, the adhesion of the fluorescent film to the glass tube is very large, without hindering the decomposition of the cobalt mixture. The present invention provides a composition for phosphor bonding (hereinafter referred to as "glass composition") to solve the above problem, so that the fluorescent film has sufficient adhesion and can be adhered to the glass tube without hindering the decomposition of the adhesive, becoming Effective adhesive, K and fluorescent lamp using this composition.

Description of the invention (4) The low-melting point glass with excellent optical body adhesion and no carbon residue, can obtain a fluorescent lamp with a good fluorescent film. Brief description of the stub form Figure 1 is the DTA curve of the glass composition obtained in Example 1 of the present invention. The example of the condyle of Ming Xiling and the condyle of Jiao Shitai Chain is described below. Generally speaking, the glass composition of the adhesive used when forming the fluorescent film of the fluorescent lamp must be operated at the baking temperature (5 00 ~ 60〇t!) And the ring fluorescent lamp during the manufacture of the fluorescent lamp. Between temperatures (700 ~ 800t!), Namely 600t: ~ 700¾ temperature range softens (first condition). The reason is that after applying the phosphor coating liquid to the inner wall of the glass tube, in order to remove the adhesive in the fluorescent film, it must be baked at 5001-60010, but in this baking step, the glass composition of the adhesive will soften , The adhesive in the fluorescent film is rolled, and the fluorescent film becomes black. To avoid this, the glass softening temperature must be set higher than the baking temperature. Therefore, the glass composition used as the binder must be insoluble in the solvent (second condition). For the aqueous phosphor coating liquid, the solvent refers to water. The reason is that if the glass composition dissolves, when the fluorescent film dries, the once-dissolved substances will re-precipitate, surrounding the organic binder, which hinders the decomposition of the organic binder during baking, and carbon remains. Therefore, the present inventors combined various metal oxides of glass constituents, changed their mixing ratio, and tested and analyzed a variety of glass compositions. The results show that Fukun has a softening point and excellent water solubility, and is suitable for fluorescent lamps.

In addition, the fluorescent lamp of the present invention is coated with 0.1 to 10% by weight, preferably 0.5 to 5,000, of the most heavy fluorescent coating solution on the wall of the glass tube. In the glass composition of the present invention, although glass-forming gasification (KVF) has B203, the water resistance and softening point are too low, which is not practical. Therefore, there must be oxides of other elements as modified oxides (NWM). The modified oxides in the glass compound of the present invention adopt the predetermined amount of divalent gold oxide (M is Hg, At least one of Ca, Sr, Ba and Zri). The addition of this divalent gold oxide oxide * can improve the glass forming performance.

Description of invention (8) Adhesion is insufficient, otherwise, if it exceeds 10% of the weight, the result is a wild light lamp Luminous brightness will decrease. Therefore, the amount of Mg added to the phosphor in the phosphor coating liquid is preferably 0.1 to 10% by weight, and preferably 0.5 to 5.0% by weight. In addition, whether the glass composition is an excellent binder can be determined according to the carbon residual state in the fluorescent film after the baking step. In the fluorescent lamp manufacturing step, is the fluorescent film peeled from the glass tube wall, Μ and coated phosphor coating The processing state of the fluorescent film surface after the liquid distribution is judged. The residual carbon in the fluorescent film can be judged by the whiteness of the body color of the glass tube after the fluorescent film formed on the meat wall of the glass tube is baked. The smaller the amount of carbon remaining, the fluorescent film will become the body color of the glass tube The whiter, the higher the reflectivity of the glass tube. The fluorescent lamp using the glass composition of the present invention as a binder can obtain a lamp tube with high reflectivity. In addition, if the bonding strength of the fluorescent screen is insufficient, the step of evacuating the tube after forming the fluorescent film on the inner wall of the glass tube, that is, when the tube is evacuated, or when argon gas is quickly introduced into the tube, is placed at the end of the tube Found that there is a flick chirp. When the glass composition of the present invention is used as a binder, no flake flakes are seen when the film is used in a predetermined amount, and no abnormality is seen on the film surface.

Print A7 B7 5. Description of invention (9) The temperature at point A of the medium (see Garden 1) is the softening point. When the softening point is in the range of 600 ~ 700t: it can be concluded that the glass composition is a good adhesive for the fluorescent film for ring fluorescent lamps. When the water solubility of the glass composition is regulated, the glass composition is subjected to dissolution treatment according to the test method for glassware for chemical analysis specified in JIS R 3502. First, crush the sample, select 250-420i / m, remove the powder, wash it with K ethyl yeast and dry it, weigh the specific gravity M (the same gram in the same specific gravity value), and load it with deionized water 100g In a 250-liter-capacity tank, after rolling at a speed of ΙΟΟγρμ for 20 hours, titrate the conductivity of the dissolution treatment liquid. This value is the number of water solubility. The lower the conductivity value, the better the water solubility. When the value is below about 200 i / S / c®, it is better than the water solubility of the conventional fluorescent glass bonding glass composition. This value is 1 5 0 w S / cm K, the water resistance will be better, so it can be seen that in the present invention, when the conductivity of the glass composition elution treatment liquid obtained by the above treatment is less than 20〇S / cm, it can be kept practical as a phosphor binder The water-based Ο Window Example 1 Take the raw material compounds shown in Table 1 and mix CaO, B203, A 1 2 0 3, and Ta 2 05 in a 20: 60: 15: 5 molar ratio, mix thoroughly, and put in The platinum crucible was heated and melted in a 1 400 10 electric furnace for 120 minutes.
