Problems solved by technology

This glass fiber does obtain good mechanical properties, but it can be seen from its practical examples that due to the reduction of Li 2 O dosage, in order to balance its production difficulty, it added more than 1% Na 2 O, and this may have more side effects

preparation example Construction

[0038] The present invention has no special restrictions on the preparation method of the glass fiber, and it can be a method well known to those skilled in the art, preferably a tank kiln method, which can be prepared according to the following method:

[0039] According to the formula, the various raw materials are mixed uniformly and put into the kiln. After melting, clarification and homogenization, the glass liquid is obtained;

[0040] The glass fiber is obtained after temperature adjustment, flow out and wire drawing treatment of the molten glass.

[0041] The invention first mixes various raw materials in a mixing tank according to formula calculations, and after they are evenly mixed, they are transported to the tank kiln silo; then the tank kiln silo automatically puts the batch materials into the tank kiln in a quantitative manner at a temperature of 1400-1800°C Melt, clarify and homogenize under conditions to obtain qualified molten glass;

[0042] Cool the liquid glass to...

Embodiment 1

[0048] Transport the raw materials to the mixing tank according to the calculated formula, and after they are evenly mixed, they are transported to the kiln silo through the batching system. The formula is shown in Table 1

[0049] The batch materials in the silo of the tank kiln are automatically put into the tank kiln in a quantitative amount. In the tank kiln, the batch materials are gradually melted into molten glass at a high temperature above 1400 ℃. After clarification and homogenization, the stable and high-quality molten glass enters the drawing operation aisle;

[0050] After the glass liquid is cooled to a suitable temperature in the wire drawing channel, it flows out through the platinum drain plate, and is quickly drawn by the wire drawing machine into a glass wire with a diameter of 3-25μm. After the glass wire is spray-cooled, coated with a sizing agent, and bundled, it is wound into Silk cake

[0051] All silk cakes can be produced into various glass fiber products t...

Embodiment 2～6

[0054] The preparation method is the same as in Example 1, except that the glass formula content has changed, as shown in Table 1.

[0055] The performance test of the glass fiber was performed, and the results are shown in Table 1. Table 1 is a formula and performance data table of the glass fiber provided in the embodiment and the comparative example of the present invention.

Abstract

The invention relates to a high-performance fiberglass composition and fiberglass. The high-performance fiberglass composition provided by the invention is prepared from the following components in percentage by weight: 50 to 55.9 weight percent of SiO2, 20.1 to 24 weight percent of Al2O3, 70.5 to 79.5 weight percent of total content of SiO2 and Al2O3, 0.2 to 1.5 weight percent of TiO2, 0 to 2.0 weight percent of ZnO, 0 to 2.0 weight percent of ZrO2, 0.1 to 0.6 weight percent of Fe2O3, 4 to 8 weight percent of CaO, 12.1 to 17 weight percent of MgO, 16.5 to 24.5 weight percent of total contentof CaO and MgO, 3.5 to 6 weight percent of B2O3 and 0.2 to 1.0 weight percent of total content of Li2O, Na2O and K2O, wherein the total content of the components is 100 percent. By controlling specific percentage contents of all components, the high-performance fiberglass composition which is finally obtained has high modulus, low production difficulty and good comprehensive performance.

Description

Technical field [0001] The invention relates to the technical field of inorganic non-metallic materials, in particular to a high-performance glass fiber composition and glass fiber. Background technique [0002] Glass fiber is an inorganic non-metallic material. It has many advantages such as high mechanical strength, good electrical insulation, strong heat resistance, and stable physical and chemical properties. It is widely used in aerospace, automobiles, ships, petrochemicals, energy, electricity, construction, etc. In many fields, it is currently the most widely used inorganic fiber reinforced material. Because it is mainly used as a reinforcing substrate, the mechanical properties of glass fibers are particularly important. With the development trend of glass fiber composite materials becoming larger and lighter, people are concerned about the mechanical properties of glass fibers, especially the specific strength and specific modulus. The modulus puts forward higher and hi...
