Example Embodiment

[0031] The present invention has no particular limitation to the preparation method of the glass fiber, which can be a method well known to those skilled in the art, preferably produced by a kiln method, and specifically can be prepared according to the following method:

[0032] Mix all kinds of raw materials evenly and put them into the kiln. After melting, clarifying and homogenizing, the glass liquid is obtained;

[0033] The glass fiber is obtained by cooling, flowing out and drawing the molten glass.

[0034] In the present invention, various raw materials are first mixed in a mixing tank, and after the mixing is uniform, they are transported to the kiln silo; then the kiln silo puts the mixed materials into the kiln, and melts, Clarify and homogenize to obtain glass liquid;

[0035] Cooling the glass liquid to 1200-1300° C., flowing out through a platinum leakage plate, and drawing into a glass wire with a diameter of 3-25 μm under the pulling of a wire drawing machine...

Example Embodiment

[0039] Example 1

[0040] The raw materials are transported to the mixing tank, and after mixing evenly, the mixture is transported to the kiln silo, and the content of the raw materials is shown in Table 1;

[0041] The mixture in the silo of the pool kiln is put into the pool kiln. In the pool kiln, the mixture is gradually melted into molten glass at a high temperature above 1400 °C. After clarification and homogenization, the stable and high-quality molten glass enters the wire drawing operation channel. ;

[0042] After cooling the glass liquid in the wire drawing operation channel to a suitable temperature, it flows out through the platinum bushing, and is quickly drawn by the wire drawing machine into glass filaments with a diameter of 3-25 μm. silk cake;

[0043] After all the silk cakes are dried, wound or chopped, various types of glass fiber products are obtained.

[0044] The performance test of the glass fiber is carried out, and the results are shown in Table ...

Abstract

The invention provides a high-performance glass fiber composition and glass fiber easy for scale production. The composition is prepared from the following components: 58.2-60.4 percent by weight of SiO2, 16.5-19.8 percent by weight of Al2O3, the total content of SiO2 and Al2O3 being 76-79 percent by weight, and the mass fraction ratio of Al2O3/SiO2 being 0.27-0.34; 9-10.5 percent by weight of CaO, 10.1-11.6 percent by weight of MgO, the total content of CaO and MgO being 20.1-21.5 percent by weight, and the mass fraction ratio of MgO/CaO being 1.01-1.27; 0-3.0 percent by weight of B2O3, and the total content of B2O3 and SiO2 being 58.5-62.2 percent by weight; 0.2-1.5 percent by weight of TiO2; 0.1-0.5 percent by weight of Fe2O3; the total content of Na2O, K2O, and Li2O being 0.2-1.0 percent by weight; and the total content of remaining impurity components being not more than 1 percent by weight. The components of the glass composition and the specific relationship between the components are precisely defined, and high-performance glass fiber easy for scale production is obtained, has excellent mechanical properties and low production difficulty, and can implement scale productionat a lower cost under the condition of the prior art.

Description

technical field [0001] The invention relates to the technical field of inorganic non-metallic materials, in particular to a high-performance glass fiber. Background technique [0002] Glass fiber belongs to inorganic non-metallic materials. It has many advantages such as high mechanical strength, good electrical insulation, strong heat resistance, stable physical and chemical properties, etc. It is widely used in aerospace, automobiles, ships, petrochemicals, energy, electric power, construction, etc. It is currently the most widely used inorganic fiber reinforced material in many fields. Because it is mainly used as a reinforcing base material, the mechanical properties of glass fibers are particularly important. Therefore, it is the constant pursuit of technicians in the industry to develop glass fiber compositions with increasingly excellent mechanical properties and easy to achieve large-scale production. [0003] Based on the basic theory of silicate glass, glass fiber...
