Embodiment Construction

[0031] In order to better understand the present invention, the content of the present invention is further illustrated below in conjunction with the examples, but the content of the present invention is not limited to the following examples.

[0032] Embodiments of the present invention are shown in the following table:

[0033]

[0034] Calculate the required amount of various raw materials according to the chemical composition of the formulas listed in the above table, and mix them evenly to make batches after accurate weighing, mix them by air force and transport them to the feeding port of the kiln, and use an automatic feeding machine to feed them. At about 1620°C, a clarified and homogenized molten glass is obtained by melting in a furnace combined with electric melting or thermal power. The melted glass liquid can be prepared into glass balls (or use a one-step kiln for direct yarn production), and then the melted glass balls can be remelted at 1560°C in a platinum-...

Abstract

The invention discloses a high-performance glass fibre, which comprises the following components in parts by weight: 55-67 parts of SiO2, 20-27 parts of Al2O3, 8-15 parts of MgO, 0-1.0 part of Li2O, 0-1 part of CeO2, 0-1 part of Na2SO4, 0-2.5 parts of SnO2, 0-2.5 parts of TiO2, 0.1-2 parts of ZrO2, and 0-4 parts of B2O3, wherein the contents of CeO2, Na2SO4 and SnO2 are not zero at the same time; and the contents of TiO2, ZrO2 and B2O3 are not zero at the same time. By means of the synergistic effect of various raw materials, the high-temperature clarification effect and the melting quality of molten glass are increased; the forming technical performance of the high-performance glass fibre is improved; and the high-performance glass fibre has the characteristics of being light in weight, high-temperature resistant, acid-resistant, high in strength and the like.

Description

technical field [0001] The invention belongs to the field of composite materials, and in particular relates to a high-performance glass fiber. Background technique [0002] High-performance glass fiber was developed gradually with the needs of the aerospace industry in the 1960s. Compared with ordinary alkali-free glass fiber, the tensile strength of the original fiber is more than 40% higher, and it has high wave permeability and corrosion resistance. , high temperature resistance, good mechanical properties, good impact resistance, good chemical stability and good fatigue resistance and other excellent comprehensive properties, mainly used in aviation, aerospace, and high-end sports equipment and other fields. [0003] High-performance glass fiber is more difficult to produce than traditional glass fiber. In a kiln with the same parameters, it requires a higher melting temperature, and the output is low and the cost is high. However, the manufacturing process of high-stre...
