The present invention relates to a glass composition for fibers. Long glass fibers are produced by melting raw materials for glass preparation, pulling out the resulting molten glass from a bushing, and stretching it. The difficulty of melting and spinning operations and the quality of the obtained glass fibers are mainly determined by the glass composition. Glass compositions have been proposed, one of which is E-glass, which is widely used. Although it is desired that the glass composition has the following properties, it is difficult to satisfy all of these properties. (1) The glass raw materials must be easily melted and homogenized, (2) The melting temperature must be as low as possible, (3) The working temperature must be as low as possible. , homogenization takes time, productivity decreases, fuel consumption increases, and glass melting furnaces tend to deteriorate. (4) The viscosity near the working temperature is within the appropriate range; (5) The liquid phase temperature is low and solid phase precipitation is difficult. If the above two conditions are not met, thread breakage is likely to occur. (6) The obtained glass fibers have high tensile strength, water resistance, and weather resistance, and are not colored. (7) The raw materials are easy to obtain and the volatilization of the raw materials during melting is small. The present invention minimizes the B 2 O 3 component, which is difficult to obtain raw materials and is easily volatilized and dissipated, and satisfies the above conditions, and particularly reduces the incidence of yarn breakage during spinning. It is an object of the present invention to provide a glass composition for fibers which has a low pull (product weight that can be manufactured in one hour with a given equipment) and an improved pull. The present invention uses SiO 2 , B 2 O 3 ,
Contains Al 2 O 3 , CaO, and R 2 O, and the proportions of these components are SiO 2 53 to 57 wt%, B 2 O 3 3.0 to 5.8 wt%,
Al2O3 13 ~17wt%, CaO25.3~27wt%, R2O0.2 ~
The present invention relates to a fiber glass composition characterized in that the glass composition contains 1 wt%. Although not essential, TiO 2 , BaO,
MgO, F, Fe2O3 , ZrO2 , TiO2 ≦2wt% ,
BaO≦1wt%, MgO≦2wt%, F≦0.6wt%,
It may be contained within the range of Fe 2 O 3 ≦0.6wt% and ZrO 2 ≦0.5wt%. Next, the present invention will be explained in more detail. In the present invention, as essential components, SiO 2 ,
It contains B 2 O 3 , Al 2 O 3 , CaO, and R 2 O. Then, the ratio of each component is determined within the above range. Increasing the amount of CaO, R 2 O, B 2 O 3 improves meltability but decreases water resistance. On the contrary, CaO,
When the amounts of R 2 O and B 2 O 3 are reduced, water resistance improves, but meltability decreases. Increasing the amount of Al 2 O 3 improves water resistance but reduces meltability. Conversely, reducing the amount of Al 2 O 3 improves meltability but reduces water resistance. The amount of SiO 2 is determined in relation to the amounts of each of the above components, but in general, increasing the amount of SiO 2 tends to lower the meltability and increase the viscosity at a given temperature. By controlling the amounts of each of the above components within the above-mentioned ranges, it was possible to obtain glass that satisfies the above-mentioned conditions and is suitable for industrial production of long glass fibers. The physical properties of the glass having the composition of the present invention are comparable to those of conventional E-glass, and what is noteworthy is that the incidence of yarn breakage during spinning is low;
It is possible to improve the pull. In addition, in the glass composition of the present invention, the following subcomponents can be added to the above-mentioned essential components. For example, 0.5 wt% or less of ZrO 2 can be added as a subcomponent to improve the alkali resistance (if the amount of ZrO 2 is too large, the meltability will decrease). Furthermore, by adding 2 wt% or less of TiO 2 as a subcomponent, the meltability can be improved (if the amount of TiO 2 is too large, the glass will become colored). In addition, BaO can be added within a range not exceeding 1wt%, which reduces the amount of B 2 O 3 and
Water resistance can be improved. Furthermore, MgO
2wt% or less, Fe 2 O 3 0.6wt% or less, F 0.6wt
It is also possible to add less than %. Note that Fe 2 O 3 is likely to be mixed as an impurity in glass raw materials, and ZrO 2 is likely to be dissolved from refractories and present in glass. All of these are impurities and are not essential components of the composition of the present invention. In addition, as mentioned above, BaO, TiO 2 and MgO have a
It can be expected to have the effect of improving water resistance and corrosion resistance, and may be added as a glass component within the above range, but is not an essential component. Next, examples of the present invention will be shown. Glass having the following composition was melted and yarn was taken.
