preparation example Construction

[0030] The present invention does not have special limitation to the preparation method of described glass fiber, can be the method well-known to those skilled in the art, preferably is the tank kiln method production, specifically can be prepared according to the following method:

[0031] Mix all kinds of raw materials evenly and put them into the tank kiln. After melting, clarification and homogenization, the glass liquid is obtained;

[0032] The glass fiber is obtained after the glass liquid is cooled, flowed out and drawn.

[0033] In the present invention, various raw materials are firstly mixed in a mixing tank, and after mixing evenly, they are transported to the tank kiln silo; then the tank kiln silo puts the mixed material into the tank kiln for melting, clarification and homogenization to obtain molten glass;

[0034] Cool the glass liquid to 1250-1350°C, flow out through the platinum bushing, and draw it into glass filaments with a diameter of 3-25 μm under the ...

Embodiment 1

[0040] Each raw material is transported to the mixing tank, and after mixing evenly, the mixed material is transported to the tank kiln silo, and the content of each raw material is as shown in Table 1;

[0041] Put the mixed material in the kiln silo into the kiln. In the kiln, the mixed material is gradually melted into molten glass at a high temperature above 1400°C. After clarification and homogenization, the stable and high-quality molten glass enters the wire drawing operation channel ;

[0042] After the glass liquid in the wire drawing operation channel is cooled to a suitable temperature, it flows out through the platinum bushing plate, and is quickly drawn into glass filaments with a diameter of 3-25 μm by the wire drawing machine. into silk cake;

[0043] After all the silk cakes are dried, wound or chopped, various types of glass fiber products are obtained.

[0044] Performance tests were performed on the glass fibers, and the results are shown in Table 1. Table...

Embodiment 2～15

[0046] The preparation method is the same as in the examples, except that the content of various raw materials has changed, as shown in Table 1 for details.

[0047] Performance tests were performed on the glass fibers, and the results are shown in Table 1. Table 1 is the formula and performance data table of the glass fibers provided in the examples and comparative examples of the present invention.

Abstract

The invention provides a novel high modulus glass fiber composition, comprising the following components: SiO 2 53wt%~55.9wt%; Al 2 o 3 21.1wt%~23.9wt%; SiO 2 with Al 2 o 3 The total content of 76.5wt% ~ 79wt%; Al 2 o 3 / SiO 2 Mass fraction ratio 0.38~0.45; TiO 2 0.3wt%~1.5wt%; Fe 2 o 3 0.1wt%~0.5wt%; CaO 8.2wt%~9.9wt%; MgO 9.9wt%~11.8wt%; CaO and MgO total content 18.8wt%~21.6wt%; MgO / CaO mass fraction ratio 1.01~1.41; Na 2 O and K 2 The total content of O is 0.2wt%-1.0wt%; the total content of other impurity components is not more than 1wt%. In the present invention, by controlling the specific percentage content of the above-mentioned components, the finally obtained high-modulus glass fiber has extremely high tensile modulus, low molding temperature and good molding performance.

Description

technical field [0001] The invention relates to the technical field of inorganic non-metallic materials, in particular to a novel high modulus glass fiber composition and glass fiber. Background technique [0002] Glass fiber belongs to inorganic non-metallic materials. It has many advantages such as high mechanical strength, good electrical insulation, strong heat resistance, stable physical and chemical properties, etc. It is widely used in aerospace, automobiles, ships, petrochemicals, energy, electric power, construction, etc. It is currently the most widely used inorganic fiber reinforced material in many fields. Because it is mainly used as a reinforced base material, the mechanical properties of glass fibers are particularly important, and with the development trend of increasing size and weight of glass fiber composites, people have more and more questions about the mechanical properties of glass fibers, especially the tensile modulus. higher requirements.
