Boron and fluorine-free glass fiber composites

摘要

This invention discloses a kind of boron and fluorine-free fiberglass composite with its characteristic that it has the following compounds under particular mix ratio: SiO2, Al2O3, SiO2+Al2O3, CaO, MgO, TiO2, ZnO, Na2O+K2O and Fe2O3. The preferential process of this invention is: selection of mineral→grinding of mineral→compounding as per ratio→melting in furnace→outflow from platinum bushing→fiberizing→coating of infiltrating liquid→protofilament drying. Compared with the traditional E fiberglass, the composite of this invention has better mechanical performance (tensile strength increased by over 15% and elastic modulus increased by over 5%) and better corrosion resistance (resistance of acid and alkali increased by 20 times); its forming temperature (<1280° C.) and forming range (>80° C.) are proper with good fiberizing performance, which can be produced in large scale.
