Abstract

The invention provides a basalt ferromagnetic glass fiber as well as a preparation method and application thereof. The glass fiber is prepared from the following chemical components in percentage by mass: 29 to 45 percent of SiO2, 4 to 15 percent of Al2O3, 28 to 40 percent of Fe2O3, 1 to 10 percent of B2O3, 5 to 12 percent of CaO, 3 to 8 percent of MgO and 1 to 2 percent of Na2O. Basalt, alumina powder, iron oxide powder, boric acid, calcium carbonate and magnesium oxide are prepared into a uniformly mixed batch; and the batch is subjected to melting, clarifying, homogenizing, cooling, throwing threads and drying to obtain the product. Basalt is used as a main raw material to prepare the ferromagnetic glass fiber with a high additional value, so that the additional value of basalt is greatly improved, and the application field of basalt is broadened. The prepared basalt ferromagnetic glass fiber can be used as a base material to synthesize tubular, flaky, columnar, blocky and other composite materials, and is widely applied to the fields of civil affairs and military affairs.

Description

technical field [0001] The invention relates to a basalt ferromagnetic glass fiber and a preparation method and application thereof, belonging to the technical field of glass fiber production. Background technique [0002] Basalt is a rock with a dense or foamy structure formed by cooling and solidifying magma from volcanic eruptions. It is the most important component of the Earth's oceanic crust and the moon's maria, and is also an important component of the Earth's continental crust and the moon's land. substance. The main component of basalt is SiO 2 、Al 2 o 3 , Fe 2 o 3 , CaO, MgO, Na 2 O etc., where SiO 2 The content is the most, accounting for about 50%. Basalt fiber produced from basalt not only has high strength, but also has various excellent properties such as electrical insulation, corrosion resistance, and high temperature resistance. It is a new type of green inorganic environmental protection high-performance fiber material. The production process of ...
