Abstract

The invention relates to a method for preparing fiber reinforced foam glass, comprising the following steps: washing, drying and grinding waste glass into glass powders, then putting glass powders, calcium carbonate, potassium permanganate, ferric oxide, boric acid and sodium nitrate into a mixer for uniformly mixing, adding aluminum silicate fiber into the mixer, adding polyvinyl alcohol, n-amyl acetate, alcohol, distilled water and polyethylene glycol 2000 based on the above mixture in the mixture and fibers as the reference, mixing uniformly and pouring slurry into a mould; then pushing the mould filled with the slurry into a foaming kiln, heating for drying, volatilizing organic compounds, foaming, cooling and annealing to obtain fiber reinforced foam glass. As the invention adopts a slurry suspension method to prepare the fiber reinforced foam glass, fibers are distributed uniformly in foam glass, and the mechanical strength of samples is high; and the fiber reinforced foam glass has wider use range than the common foam glass and long service life, and can absorb main parts of explosion energy when facing shock waves.

Description

technical field [0001] The invention relates to a method for manufacturing foam glass, in particular to a method for preparing fiber-reinforced foam glass. Background technique [0002] In the past few decades, there have been many terrorist attacks on government buildings in some countries in the world. For example, in 1993, terrorists detonated a car bomb in the garage of the World Trade Center in New York City, causing significant loss of life and property. In 1995, extremists blew up a truck outside a federal building in Oklahoma City, causing significant loss of life and property. In 1998, the U.S. embassies in Nairobi and Dar es Salaam were also attacked by terrorist car bombs, causing heavy loss of life and property respectively. The 2002 disasters at the World Trade Center in New York City and the Pentagon in Virginia further underscored the urgent need to develop and manufacture building materials that can withstand the shock waves of car bomb blasts and other sim...
