Abstract

PURPOSE:To provide an artificial marble excellent in hydrothermal resistance and rich in transparent performance. CONSTITUTION:A ternary system glass filler having a composition containing 50-65% SiO2, 10-20% Al2O3, 20-30% CaO, <=0.1% B2O3 and <=3% R2O3 is dispersed into a polyester resin. The artificial marble excellent in transparent performance is obtained since the refractive index of the glass filler coincides with the refractive index of the polyester resin.

2. 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 has, for example, the following composition.

The present invention has been completed in order to solve the above-mentioned conventional problems and provide an artificial marble which is more excellent in hot water resistance and transparency than conventional products. 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 the B 2 O 3 and R 2 O components contained in a large amount in the composition of the glass filler. I knew it was the cause.

As described above, the present invention is characterized by the composition of the glass filler, and unlike the conventional composition, B 2
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 artificial marble in which glass filler having such a special composition is dispersed is Previously unknown.

Further, SiO 2 -Al containing no B 2 O 3 and R 2 O
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 becomes 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 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.
