Embodiment 1

[0059] The raw material of the present invention can be prepared into glass or glass fiber, and the standard for judging whether it can be drawn is the analysis of the thermal properties of the glass. The method of preparing glass is to cast and anneal the molten glass formed by melting raw materials; the method of preparing glass fiber is to draw the molten glass formed by melting raw materials at the drawing temperature according to the conventional process. The present invention tests the relevant technical parameters of the glass fiber, which has nothing to do with the mechanical properties, so it only needs to be made into a glass sample for testing.

[0060] Weigh the raw materials according to the raw material formula in Table 2 below, and prepare them into glass samples. In the lifting crucible electric furnace, melt at 1500°C for 3 hours and pour it into the graphite mold, and then send it into the lifting crucible electric furnace for annealing (cast the glass liquid...

Abstract

The invention discloses a boron-free high-performance glass fiber and a preparation method thereof and belongs to the technical field of materials. The boron-free high-performance glass fiber is prepared from the following raw materials in percentage by weight: 30-55% of blast furnace slag, 1-15% of fly ash, 42-50% of quartz sand, 0-15% of zinc oxide, 0-2% of magnesium oxide and 0-3.5% of calcium oxide. According to the boron-free high-performance glass fiber, the adversely effects of the volatilization of boron on a kiln, the environment and the production cost are avoided, and the boron-free high-performance glass fiber has the advantages of excellent performance, reasonable process parameters, low production cost and environmental friendliness and furthermore, the raw materials can directly adopt industrial-grade raw materials and the effect is not affected.

Description

technical field [0001] The invention relates to the technical field of materials and prepares boron-free high-performance glass fibers containing zinc oxide, which can be used as reinforcing materials for composite materials. Background technique [0002] Calcium-aluminum-silicate glass is mainly used in the fields of glass-ceramic and glass fiber. The commonly used E-glass fiber is developed on the basis of calcium-aluminum-silicate system. Calcium-aluminum-silicon system glass fiber has good mechanical properties, good chemical stability and thermal stability, etc., and is the basic material for industrial development. It is mainly used in the electronics industry and the field of composite materials, such as printed circuit boards and other composite materials products. However, with the development of science and technology, higher requirements are put forward for the performance of materials. Therefore, it is essential to study high-performance glass fibers-calcium-alu...
