High-performance glass fiber ingredient and glass fibers prepared from same

Abstract

The invention discloses a high-performance glass fiber ingredient which comprises the following components in percentage by mass: 50-65wt% of SiO2, 10-18wt% of TiO2, 10-16wt% of CaO + MgO, 6-11wt% ofLi2O + Na2O + K2O, 0.1-2 wt% of Al2O3, 0-2wt% of ZrO2, 0.5-2 wt% of Y2O3 + La2O3 + CeO2, 0-2wt% of B2O3 and 0.1-1 wt% of Fe2O3. In the ingredients of the glass fiber, the high-performance glass fibercan be prepared with low cost and high efficiency by using the extremely low content of Al2O3 and ZrO2 while using the high content of TiO2. Specifically, the raw materials are put into a melting device, glass fiber ingredients are melted in advance, then molten glass is subjected to wiredrawing forming through a pore plate, and the high-performance glass fiber can be obtained.

Description

technical field [0001] The invention relates to the field of glass fiber, in particular to a high-performance glass fiber ingredient and the glass fiber prepared therefrom. Background technique [0002] The main component of glass fiber is silica. According to the performance of the specific use of glass fiber, the most commonly used glass fiber mainly includes SiO 2 -Al 2 o 3 -ZrO 2 , SiO 2 -Al 2 o 3 -B 2 o 3 , SiO 2 -Al 2 o 3 -RO (R is Mg, Ca), SiO 2 -Al 2 o 3 -R 1 2 O(R 1 Na, K, Li) and other systems, and then add various modification components, such as Fe 2 o 3 , ZnO, P 2 o 5 , F, SO 3 , Y 2 o 3 , La 2 o 3 , CeO 2 、Gd 2 o 3 、Sm 2 o 3 、TiO 2 , CuO, Nb 2 o 5 、WO 3 Wait. [0003] For the preparation of glass fibers, manufacturers usually need to make a compromise between performance and the ease of operation and cost of the preparation process. As we all know, in the process of glass fiber preparation, the glass fiber ingredients need t...

AI Technical Summary

Problems solved by technology

There are some components used in glass fiber ingredients, such as Y 2 o 3 , La 2 o 3 , CeO 2 etc., can effectively improve the modulus properties of glass fibers, but the price of its rare earth oxides is relatively high, and a large amount of rare earth oxides will increase the cost of glass fibers

[0004] Due to the problems that high-performance glass fibers are difficult to prepare and high production costs always exist in the production process of existing glass fibers, the purpose of the present invention is to provide high-performance glass fiber ingredients, and the glass fiber ingredients are easy to produce glass Fiber, so as to obtain high-performance glass fiber with good production operability and low cost
