Problems solved by technology

[0009] Although these disclosed technical schemes have obviously improved the refractive index of the glass fiber, all of the above-mentioned technical schemes mention adding a certain amount of BaO and ZrO in the glass components. 2 , which will increase the density of the glass, thereby increasing the unit weight of the final product, and weakening the advantages of light weight and high strength of the composite material
At the same time, if the amount of BaO introduced is too high, it will affect the strength of the glass fiber, while ZrO 2 If the amount introduced is too high, it will increase the tendency of glass devitrification and increase the difficulty of glass fiber forming

preparation example Construction

[0070] The preparation method of the glass fiber is not particularly limited in the present invention, and it can be prepared according to the tank kiln method well known to those skilled in the art.

[0071] The tank kiln method is as follows: calculate the required raw material addition ratio according to the actual glass formula; transport various raw materials quantitatively to the mixing bin according to the ratio, and mix them thoroughly to obtain qualified batch materials; transfer the batch materials to the tank. The kiln head hopper of the kiln is delivered to the pool kiln at a uniform speed by the feeder; the batch material is heated, melted, clarified and homogenized in the pool kiln at a high temperature of 1300-1500°C to form qualified molten glass; the molten glass passes through the working channel Cool to the molding temperature, and then flow out through the platinum bushing to form glass filaments; the glass filaments are quickly drawn into glass fibers with ...

[0075] The glass fiber was prepared by the tank kiln method. Table 1 shows the chemical composition of the glass composition of each embodiment and comparative example, and the unit is mass percentage.

[0076] Calculate the required raw material addition ratio according to the actual glass formula; according to the ratio, various raw materials are quantitatively transported to the mixing bin, fully mixed evenly, and qualified batch materials are obtained;

[0077] Convey the batch material to the kiln head silo of the tank kiln, and deliver it to the tank kiln at a uniform speed by the feeder;

[0078] After the batch materials are heated, melted, clarified and homogenized at a high temperature of 1300-1500 ℃ in the tank kiln, qualified glass liquid is formed;

[0079] The molten glass is cooled to the molding temperature through the working channel, and then flows out through the platinum bushing to form glass filaments; the glass filaments are quickly drawn into glass fiber...

Abstract

The invention provides a glass fiber, which comprises the following components: 58 to 63 percent by weight of SiO2 (silicon dioxide); 9 to 13 percent by weight of Al2O3 (aluminum oxide); 18 to 24 percent by weight of CaO (calcium oxide); 1 to 4 percent by weight of MgO (magnesium oxide); 2 to 4 percent by weight of TiO2 (titanium dioxide), 2 to 4 percent by weight of ZnO (zinc oxide), 0.05 to 0.3 percent by weight of Fe2O3 (iron oxide) and 0.2 to 1 percent by weight of Li2O (lithium oxide), Na2O (sodium oxide) and K2O (potassium oxide); and the mass percentage sum of the TiO2 and ZnO is 5 to 7 percent. The refraction index of the glass fiber is 1.581 to 1.587 and can be well matched with the refraction index of the polycarbonate resin. Secondly, the density of the glass fiber is moderate and ordinary alkali-free glass, when the glass fiber is used for substituting the ordinary alkali-free glass to enhance the PC resin, the light weight and convenience of a composite material can be guaranteed. In addition, the mechanical performance and chemical stability are good.

Description

technical field [0001] The invention relates to the field of glass fibers, in particular to glass fibers. Background technique [0002] As an excellent inorganic non-metallic material, glass fiber has high tensile strength, high specific strength, good temperature resistance, corrosion resistance, heat insulation, sound insulation, and non-combustibility. It is widely used in electronics, electricity, automobiles, aviation, and ships. , environmental protection, chemical industry, construction and other fields of the national economy. According to the glass composition, glass fiber can be divided into alkali-free glass fiber, chemical-resistant glass fiber, high-alkali glass fiber, medium-alkali glass fiber, high-strength glass fiber, etc. Among them, alkali-free glass fiber (lower part of E glass) is the most widely used glass fiber. [0003] Glass fibers are often used as reinforcing agents in composite materials to improve the performance of composite materials. For gl...
