物に関するものである。FIELD OF THE INVENTION The present invention relates to a glass composition,
In particular, the present invention relates to a glass composition which can be composited with a polycarbonate resin (hereinafter referred to as PC resin) in a fibrous, powdery or beaded form and can be strengthened without impairing the transparency of the resin.

全カバー、計器カバー等の材料として最適である。2. Description of the Related Art PC resin refers to carbonic acid ester formed by the reaction of bisphenol A and phosgene. Since it is superior in heat resistance and impact resistance to other thermoplastic resins, it is a versatile engineering plastic. Since it is used for various purposes and has excellent transparency, it is ideal as a material for safety covers, instrument covers, etc.
【０００３】従来より樹脂の強化には、Ｅガラスと呼ば
れるガラス繊維が主に使用されているが、このＥガラス
繊維でＰＣ樹脂を強化すると、樹脂の透明性が低下し、
望ましくない外観を呈するという問題が生じる。Conventionally, glass fibers called E glass have been mainly used for strengthening resins, but if PC resin is reinforced with this E glass fiber, the transparency of the resin decreases,
The problem arises of exhibiting an undesirable appearance.

ラス繊維との界面で光線が散乱し、ガラス繊維が白色に
光って樹脂の透明性が損なわれるからである。This is because the refractive index of PC resin is about 1.585.
On the other hand, since the E glass fiber has a refractive index of about 1.560, and the refractive indices of the two are significantly different, light rays are scattered at the interface between the PC resin and the glass fiber, and the glass fiber shines white and becomes a resin. This impairs the transparency of.

されている。Therefore, in order to maintain the transparency of the PC resin, a glass having a refractive index close to or substantially equal to the refractive index of the PC resin has been proposed.
No. 1338 discloses a glass fiber composition having a refractive index of 1.570 to 1.600 and not impairing the original transparency of the resin even when mixed in a PC resin in the form of a fiber. ing.

The glass fiber composition disclosed in 2-1338 discloses Ti
For containing O 2 5.3 wt% or more, the glass fiber itself is colored brown and this placed in PC resin, it has the disadvantage that resin is seen colored. In particular, when the content of the glass fiber is increased for the purpose of improving the impact resistance of the resin, coloring becomes severe, which is not preferable.

し、成形工程に悪影響を及ぼす。Further, the glass fiber composition contains alkali metal oxides of Na 2 O, K 2 O and Li 2 O in an amount of 3 to 3, respectively.
Since it contains a large amount of 8%, 3-8%, 0-5%,
When it is placed in the resin, the hydrolysis of the resin occurs due to the alkali ions eluted from the glass, and the molecular weight of the resin decreases. When the molecular weight of the resin decreases, the shrinkage rate of the resin changes, which adversely affects the molding process.

O 2, containing BaO and ZnO in specific proportions, thereby being adjusted refractive index 1.5700 to 1.6000. In particular, ZrO 2 and TiO 2 have a large effect of increasing the refractive index, but as described above, when a large amount of TiO 2 is contained, the glass is colored, and when a large amount of ZrO 2 is contained, the liquidus temperature rises. However, the difference from the spinning temperature becomes large, and as a result, it becomes difficult to fiberize the glass, so that one component is not contained alone in a large amount, but both components are allowed to coexist at optimum values.
