Abstract

The invention discloses a novel foam glass which is prepared from the following raw materials in parts by weight: 12 to 27 parts of blast furnace slag, 5 to 22 parts of silica raw material, 20 to 40 parts of modified waste glass, 10 to 25 ceramic polishing waste, 8 to 13 parts of calcite, 9 to 21 perlite, 1.3 to 2.8 parts of aluminum oxide, 2 to 4 parts of sodium carbonate, 3 to 12 parts of borax, 0.8 to 1.4 parts of manganese dioxide, 0.7 to 1.3 parts of ferric oxide, 0.05 to 0.16 part of sodium hexametaphosphate, 1 to 5 parts of refractory fiber, 0.9 to 1.7 parts of nano medical stone powder, 0.3 to 0.7 part of nano zinc oxide, 1.1 to 2.2 parts of acetylated di-sodium starch and 0.8 to 2.4 parts of calcium carbonate. According to the novel foam glass, the blast furnace slag, the silica raw material, the modified waste glass and the ceramic polishing waste are utilized as raw materials, waste is turned into wealth, raw material source is wide, and cost is reduced; meanwhile, the refractory fiber and the nano zinc dioxide are added to serve as additives, so that performance of the foam glass is effectively improved, and strength of the foam glass is improved.

Description

technical field [0001] The invention belongs to the technical field of foam glass, and in particular relates to a novel foam glass and a preparation method thereof. Background technique [0002] Foam glass is made of waste flat glass, bottle glass as the main raw material, adding foaming agent, modifier, flux, etc., uniformly mixed by ball milling to form batch materials, and then placed in a specific abrasive tool for foaming, annealing, etc. A porous glass material filled with countless uniform bubbles formed by the process. In addition to the inherent permanence, safety, chemical corrosion resistance and protection from insects, ants and mice, foam glass also has the characteristics of light bulk density, small thermal conductivity, moisture impermeability, small water absorption, non-combustibility, and non-toxicity. Mildew, stable performance, both cold insulation material and thermal insulation material, can adapt to deep cold to higher temperature range and so on. A...
