Description of the Related Art Artificial marble in which a glass filler is dispersed in a polyester resin has been widely known, and a glass filler for this purpose is usually one having the following composition, for example.

Even though the glass filler itself is transparent, I was left with the problem that I could not get enough transparency when I did.

As a result of pursuing the cause of problems in conventional products in order to solve this problem, the present inventor reduced the hot water resistance of B 2 O 3 and R 2 O components contained in a large amount in the composition of the glass filler. I knew this was the cause.

SiO 2 − Al 2 O 3 − containing almost no O 3 and R 2 O components
The composition is a three-component system of CaO. The reason why B 2 O 3 is 0.1% or less and R 2 O is 3% or less is to significantly improve the hot water resistance, and the artificial marble in which the glass filler having such a special composition is dispersed is Previously unknown.

In order to match the refractive index with the polyester resin in the three-component glass composition of 2 O 3 —CaO, in the present invention, SiO 2 50 to 65%, Al 2 O 3 10 to 20% shown in FIG. CaO
A composition range of 20-30% was selected. Where SiO 2 is 50-60%
The reason is that if it is less than 50%, the refractive index of the glass filler does not match the refractive index of the polyester resin (1.54 to 1.55), and if it exceeds 65%, it is difficult to melt in this component system. The reason why Al 2 O 3 is set to 10 to 20% is that when the content is less than 10%, the refractive index of the glass filler still does not match that of the polyester resin, and when it exceeds 20%, it becomes difficult to melt. Further, CaO is set to 20 to 30% because if it is less than 20%, the refractive index of the glass filler does not match, and if it exceeds 30%, crystals may easily occur in the glass filler and the transparency may be lost. is there.
