Abstract

A method for preparing particle-reinforced foam glass. First, waste glass powder, silicon nitride, carbon powder, sodium nitrate, titanium dioxide and zirconium dioxide are added to a ball mill pot to obtain batch materials; then the batch materials are added to a mold, And move the mold into the foaming furnace for firing. The density of the foamed glass obtained according to the preparation method of the invention is 0.2-1.2g / cm3, the aperture is 0.3-5.0mm, and the pores are evenly distributed, and the specific strength can reach 5-20.0MPa / (g.cm-3). The foam glass prepared by the invention has high specific strength, high mechanical strength, wider application range and longer service life than ordinary foam glass. The foam glass can be combined with cement, steel or other high-strength building materials and has the advantage of a rigid structure capable of absorbing a major part of the blast energy when faced with a shock wave.

Description

technical field [0001] The invention relates to a method for manufacturing foam glass, in particular to particle-reinforced foam glass and a preparation method thereof. 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 ...
