Abstract
The invention discloses a lanthanum-doped iron phosphate alkali-resistant glass fiber and a preparation method thereof, and belongs to the technical field of rare earth doped phosphate glass. The ironphosphate glass fiber is prepared by adopting a melting-wire drawing cooling method. The glass fiber is prepared from, by mass in terms of oxides, P2O5 45-55%, Fe2O3 37-50%, CaO 2-7% and La2O3 0.5-6%. According to the glass fiber, through optimization of glass components on the basis of P2O5 Fe2O3 CaO La2O3 system components, high temperature viscosity of glass and alkali resistance of fiber areimproved to obtain the fluorine-free alkali-resistant glass fiber of which the alkali resistance is comparable to that of a conventional alkali-free glass fiber (E glass fiber), and the fluorine-freealkali-resistant glass fiber has good practicability in the field of alkali corrosion resistant materials such as glass fiber reinforced cement (GRC), battery separators and the like.
Description
technical field [0001] The invention belongs to the technical field of rare earth-doped phosphate glass, and specifically relates to a kind of lanthanum-doped iron phosphate glass that can be used as a reinforcing material in glass fiber reinforced concrete, battery separators and other materials that require corrosion resistance. Alkali glass fiber and its preparation method. Background technique [0002] Alkali-resistant glass fiber is a new type of inorganic non-metallic material with excellent properties, such as good heat resistance, corrosion resistance, high mechanical strength and other properties. Alkali-resistant glass fiber is added to the cement paste or cement mortar matrix as a reinforcing material to form a composite material with good toughness and high impact resistance - glass fiber reinforced concrete (GRC), which can be used in roads, Structural complex stress areas, bridge and tunnel engineering, etc. The price of glass fiber reinforced concrete is rel...
