Description
Technical Field
The invention belongs to the technical field of glass fiber, and particularly relates to a continuous high-strength glass fiber component and a manufacturing method thereof.
Background
The high-strength glass fiber is glass fiber drawn by glass of a silicon-aluminum-magnesium-calcium system, and has a series of excellent performances of high tensile strength, high elastic modulus, good impact resistance, fatigue resistance, high temperature resistance and the like compared with alkali-free glass fiber. The method is widely applied to the fields of aerospace, aviation, national defense and military industry, wind energy, bulletproof and the like.
With the development of times and the technological progress, various glass fiber companies develop high-strength glass fibers. Such as U.S. Pat. No. 3402055, having a composition of 65 wt% SiO2、25wt％Al2O310 wt% of MgO, the glass fiber has the advantages of high tensile strength, but the crystallization upper limit temperature of the glass fiber is 1471 ℃, the wire drawing bushing temperature is 1570 ℃, the production difficulty is high, the glass liquid has serious erosion to the refractory material of the kiln, the service life of the wire drawing bushing is short, and the production cost is high.
The domestic HS glass fiber is a high-strength glass fiber; mainly comprises oxides of silicon, aluminum, calcium and magnesium, and the components of the oxides are 52-66 wt% of SiO2、16～26wt％CaO、12～16wt％Al2O3、5～10wt％H3BO3、0～5wt％MgO、0～2wt％Na2O+K2O、0-0.8wt％TiO2、0～5wt％Fe2O30 to 1.0 wt% of F. The melting temperature is 1465 ℃, and the wire drawing temperature is 1350 ℃; although the melting temperature and the wire drawing temperature are greatly reduced; but the ecological strength is only 3600-4000 MPa.
The French R-glass fiber mainly comprises 58-60 wt% of SiO2、23.5～25,5wt％Al2O35-6 wt% of MgO and 9-11 wt% of CaO; the melting temperature is 1450 ℃, and the wire drawing temperature is 1280 ℃; but the ecological strength is 3200-3400 MPa.
The glass fiber produced by the prior art has the advantages that the nascent state strength can reach about 3400MPa or even higher, but the production technology has some defects, such as high bubble index and high wire drawing temperature, and the production is not ideal in wire breaking times, water resistance and acid and alkali resistance; large-scale industrial production cannot be realized; the introduction of the F element in the component can reduce the high-temperature viscosity of the glass, is beneficial to forming operation, but causes pollution to the environment in production. To meet the requirements of high-end fields, further improvements in the above characteristics are required.
Disclosure of Invention
Aiming at the defects in the prior art, the invention provides the high-strength glass fiber which has high tensile strength, high elastic modulus, good chemical stability and high temperature resistance.
The second object of the present invention is to provide a method for preparing the above high strength glass fiber.
The purpose of the invention can be realized by the following technical scheme:
a high strength glass fiber comprising the following components:
the technical scheme adopted by the invention is that the high-strength glass fiber system is as follows:
SiO2-Al2O3-CaO-MgO-BaO-Bi2O3-ZrO2-CeO2and contains no boride or fluoride.
In the present invention, the proportions of the glass components are mainly as follows:
SiO2is the most main network former in silicate glass and plays a main skeleton role in a glass system; the content of silicon dioxide is increased, the viscosity of the glass liquid is increased at the same melting temperature, the clarifying temperature is increased, and the wire drawing performance is deteriorated. Therefore, the silica is preferably controlled to 55 to 62 wt%.
Al2O3Belongs to intermediate oxide, can not form glass independently, but can improve the crystallization tendency of the glass, improve the chemical stability of the glass, and Al2O3The content of the lead-free glass is high, so that the liquidus of the glass is increased, the melting temperature of the glass is high, and the drawing difficulty is high; the low content is not favorable for the fiber strength and the water resistance of the glass. . Therefore, the alumina is preferably controlled to 15 to 22 wt%.
CaO belongs to network exo-ions, the high-temperature viscosity of the glass can be adjusted, the water resistance of the glass is improved, and the high content of CaO can shorten the glass frit property, increase the brittleness and increase the crystallization tendency. Therefore, the content is controlled to be 5-12 wt%
The middle action of MgO in the glass is similar to that of calcium oxide, and if MgO is used for replacing part of CaO, the crystallization capacity of the glass can be reduced and the material property of the glass can be adjusted; too high a dosage is not favorable for water resistance and reduces chemical stability. Therefore, the content is controlled to be 5 to 10 wt%.
Alkali metal Na2O and K2O is a good fluxing agent and can reduce the viscosity of the glass, but the content is increased, the free oxygen is increased, the oxygen ions in the bridge are reduced, the structure is loose, the network gap is increased, and the fiber strength is reduced. Therefore, it is preferable to control the amount of the catalyst to 0 to 0.5 wt%.
BaO is between alkali metal ions and belongs to network exo-ions. Plays a good role in fluxing in the glass melting process. Can reduce the viscosity of the glass during the formation, improve the material property of the glass, lead the glass to be easy to melt and improve the wire drawing performance. Because of the corrosiveness of BaO to refractory materials, the content of glass components is not too high, and therefore, the content is controlled to be 0.1-0.5 wt%.
ZrO2Belonging to the network outer body in the glass structure. The strength, viscosity, hardness and chemical stability of the glass can be improved, the water resistance, acid and alkali resistance of the glass are improved, and the thermal expansion coefficient of the glass is reduced; if too much is introduced, aggregation occurs in the glass, causing devitrification and phase separation of the glass, and the viscosity of the molten glass increases, so that ZrO in the present invention2The content is controlled to be 0.5-1.5 wt%.
The viscosity of the glass can be greatly reduced by adding a small amount of bismuth oxide, and the high fluxing property of the bismuth oxide is favorable for improving the melting quality of the glass and obtaining a lower bubble index; however, if the amount of the polymer is too large, the polymer tends to be polarized due to an increase in the ionic radius, and the network structure of the glass tends to be broken. Thus Bi in the present invention2O3The content is controlled to be 0.2-1.0 wt%.
CeO2Can reduce the high-temperature viscosity of the glass, and release O when the glass is melted at high temperature2And can play a good clarification role. Since CeO2Providing free oxygen at high temperature, thereby adding CeO to the glass component2Can increase the bridge oxygen in the glass network structure, make the connection between the silicon-oxygen tetrahedron tighter, improve the mechanical property and acid and alkali resistance of the fiber. However, since the content is too high and causes bubbles, the content is controlled to be 0.2 to 0.5 wt%.
The glass composition described above is designed to be free of boron compounds and fluorine compounds.
In conventional glass composition designs, it is common to includeBoron compounds and or fluorides:
boron compoundThe melting temperature and viscosity of the glass can be reduced at high temperature, and the melting and clarification of the glass can be accelerated. Fluoride can accelerate the reaction of glass formation, reduce the viscosity and surface tension of the glass liquid and promote the clarification and homogenization of the glass liquid.
But in the process of melting the high-strength glass fiber,of boron oxideVolatilization can cause poor glass uniformity, is not beneficial to wire drawing operation and has lower wire drawing yield; due to the non-uniform glass composition, the TEX of the finished yarn is non-uniform and the tensile strength is different.Fluoride compoundsOn one hand, the corrosion of refractory materials of the kiln is increased, on the other hand, the volatilization pollutes the atmosphere, and the TEX of the finished yarn is not uniform due to the volatilization of fluoride; the uneven TEX of the finished yarn can cause unqualified basis weight of glass cloth produced by downstream customers, and customer complaints are caused; borides and fluorides are not used in the glass composition.
The main technical innovation in the system of the invention is throughIntroducing micro-amount of sodium oxide, potassium oxide, barium oxide and cerium oxide Oxide of "three systemsThe content of the organic silicon compound is controlled to be 1.0-1.5 wt% as a clarifying flux; avoidance in the componentIntroduction of boride and fluorine Article of manufacture. Thereby fundamentally improving the melting effect of the glass, reducing the phase splitting and crystallization tendency of the glass, reducing the bubble index of the glass and reducing the temperature of wire drawing operation; and the glass fiber with high tensile strength is obtained, and the better water resistance, acid resistance and other properties are ensured. Because the component does not contain F, the environmental pollution caused by F volatilization in the production process can be avoided.
Further, the invention introduces a trace amountBismuth oxideIn the structural system with [ BiO6]The network exosome form exists in the glass structure, so that the network connection degree of the glass structure is reduced, the high-temperature viscosity of the glass is reduced, the melting speed of the glass is improved, and the bubble index in the glass is effectively reduced.
The preparation method of the high-strength glass fiber comprises the following steps:
