Embodiment 1-7

[0037] Table 1 shows the specific components and corresponding properties of Examples 1-7 listed in the present invention. Wherein, No.1-No.3, No.5-No.6 are preferred embodiments of the present invention, and No.4 and No.7 are comparative examples for comparison. In the performance test, the liquidus temperature, elastic modulus, alkali resistance and water resistance of the glass fiber composition and the glass fiber prepared by it were mainly tested, as well as the set suitable spinning temperature and the corresponding spinning temperature The temperature difference from the liquidus temperature.

[0038] Table 1

[0039]

[0040] It can be seen from Table 1 that in the present invention, YSZ is used to replace zirconia, which can effectively reduce the liquidus temperature of the glass fiber composition, thereby reducing the required suitable spinning temperature. At the same time, the substitution between YSZ and zirconia did not affect the alkali resistance of glass...

Abstract

The invention provides a high-modulus glass fiber with excellent alkali resistance and a preparation method thereof. The raw material of the glass fiber is 55-60% SiO 2 , 15‑20% Al 2 o 3 , 12-18% of YSZ, 0.5-2% of Y 2 o 3 +Nd 2 o 3 +CeO 2 , 5‑8% CaO+MgO, ≤2% Li 2 O+Na 2 O+K 2 O, ≤1%Fe 3 o 4 , ≤1%TiO 2 . By replacing traditional zirconia with YSZ and combining a small amount of rare earth oxide and other components, high modulus glass fibers with excellent alkali resistance can be prepared at lower spinning temperatures.

Description

technical field [0001] The invention relates to the field of glass fiber manufacturing, in particular to a high-modulus glass fiber with excellent alkali resistance and a manufacturing method thereof. Background technique [0002] High-modulus glass fiber is a composite inorganic fiber material with excellent performance, which is widely used in various fields such as aerospace, automobile manufacturing, and electronic equipment. [0003] SiO 2 -Al 2 o 3 -ZrO 2 Fiberglass is the most commonly used high modulus glass fiber. Among such high modulus glass fibers, SiO 2 As the main body of the skeleton structure, with Al 2 o 3 Al in 3+ The tetrahedral and octahedral coordination structures of SiO 2 The skeleton structure is connected, which increases the high-temperature viscosity and chemical stability of the glass. ZrO 2 It is an essential ingredient to improve the alkali resistance of glass fiber and ensure high modulus, hardness, viscosity and other properties. ...
