The present invention has been completed by finding a component system and a composition range of a soluble glass that does not cause discoloration of a synthetic resin or the like so as not to cause the above phenomenon as much as possible.

Phosphate-based glass was good, but the cause is estimated as follows. Due to the glass structure, the bond of -Si-O-Ag has a weak acidity, and thus Ag 0 is easily formed. −
The P-O-Ag bond has a strong acidity and tends to remain in the Ag + state. When the amount of R 2 O component is large, non-crosslinking oxygen ions are present and Ag 0 is easily formed. Therefore, the glass described in the means for solving the above problems is used.

すべきである。The reason for limiting the composition of the fusible glass is as follows.
It is as below. When P 2 O 5 is 45% or less, the melting property of glass becomes difficult, and the devitrification tendency of glass is increased. On the other hand, if it is 75% or more, the volatilization of P 2 O 5 at the time of melting is large, which causes composition instability, and when it is added to a resin or the like, causes discoloration to yellowish brown and increases hygroscopicity. Does not give the desired soluble glass. Ca
O + MgO is in 35% or less, it is necessary to use a large amount of P 2 O 5, has the same drawbacks as in the case of P 2 O 5 75% or more, when it more than 55%, the amount of P 2 O 5 It has the same drawbacks as the case of P 2 O 5 45% or less. N

明を明らかにする。When SiO 2 + Al 2 O 3 is 5% or less,
It becomes difficult to control the melting rate of glass, and when it is added to resin, the tendency of discoloration increases, and it is 20%.
This is because the meltability is deteriorated and the discoloration tendency is increased when the resin is added to the resin or the like. Ag 2 O is
This is because if it is 0.1 wt% or less, it is necessary to increase the amount of glass added in order to impart antibacterial and antifungal properties to the resin and the like, which is not economical and deteriorates the characteristics of the resin and the like to be added. . On the other hand, if it is 5 wt% or more, silver metal may be precipitated during melting, causing local erosion of the refractory and discoloring the resin to be added. Next, examples will be described to clarify the present invention.

The raw materials for O were mixed, and further the raw materials for P 2 O 5 were kneaded to carry out. The melting was carried out by previously evaporating the water content in the batch at 500 ° C. and solidifying, then heating to 1300 to 1350 ° C., and melting for 1 to 6 hours. The molding was performed by pouring out the glass substrate, cooling it with water, and making a granulated product. In this case, it was carried out so as to avoid contact between the glass and the metal material. Then, this glass was crushed to 20 μm or less, and a discoloration test of the glass itself was performed. The contents of the test are as follows. (1) Effect test of organic matter and heat Liquid paraffin and glass powder were mixed at a ratio of 1: 1,
Heat at 200 ° C. for 20 minutes and check the color change. (2) Effect test with ultraviolet rays and water Put glass powder in a container containing water so that it does not come in contact with water, seal it, and illuminate it with an ultraviolet lamp (450 W) for 1 hour,
I saw a color change. Table 1 shows the relationship between the glass composition and the test results.
