Description of the Related Art Phosphates, alkali silicates, silica sols and the like are known as binder components of conventional inorganic adhesives, and inorganic fillers and hardeners have been blended with these to be used as adhesives. An adhesive using a phosphate as a binder has high adhesive strength, has heat resistance of 1500 ° C. or higher, and has low reactivity with glass, and thus is often used for filling and bonding of lamps.

It is disclosed in JP-B-56-51467 to use as an adhesive for bonding a glass material and a base material constituting a glass bulb.

昭５５−１４８２０を参照。However, when such an alkali silicate-based adhesive is used for bonding glass products, there is a disadvantage that the glass is eroded by the alkali component, the strength of the glass is significantly reduced, and the glass is easily broken. For example, see Japanese Patent Publication No. 55-14820.

求される自動充填には不向きである。The drawback of this composition is that the action of the curing agent is too strong, and after it is prepared into a paste with water, it gels within a few hours. Therefore, it is necessary to prepare an adhesive each time, which is a very complicated operation. Becomes In addition, the viscosity changes over time even within several hours until gelation occurs, and thus is not suitable for automatic filling requiring stable viscosity.

Further, since fluorine ions are eluted by washing or the like, the cost of wastewater treatment is large.
