Glass pumice wall brick and making method thereof

Abstract

The invention discloses a glass pumice wall brick and a making method thereof. The glass pumice wall brick is prepared by sintering a foaming mixture, and the foaming mixture comprises, by weight, 85-93% of glass particles, 3-5% of aluminum hydroxide powder, 2-4% of heavy calcium carbonate powder and 2-4% of light calcium carbonate powder. The glass pumice wall brick contains blind hole foaming micropores, and can effectively obstruct air flowing; the diameter of the foaming micropores is 0.04-3 mm, the water-absorption rate is 0.2%, intensity is 3-8 MPa, and density is 0.5-0.6 g / cm<3>; the specific gravity is small and is only 0.3-0.8; the heat conductivity coefficient is small and smaller than or equal to 0.060 W / m.k (38DEG C). The glass pumice wall brick has the advantages of being light in weight, keeping warm, preventing fire, water and freezing, resisting acid, alkali and ageing, absorbing sound, being easy and convenient to construct, achieving integrated beatification of the appearance and saving engineering cost, will not pollute the environment during producing and using, and also has the advantage of achieving solid waste utilization of renewable resources.

Description

technical field [0001] The invention relates to a glass pumice wall brick and a preparation method thereof. Background technique [0002] At present, the materials used for thermal insulation of external walls in buildings are generally room temperature foaming materials. The thermal insulation effect is not ideal and not durable. After installation, the facade needs to be reshaped. The cost is very high, and at the same time, harmful gases will be emitted during use, which will cause certain pollution to the environment Contents of the invention [0003] The purpose of the present invention is to provide a light weight, good heat insulation effect, acid and alkali resistance, impermeable, fire prevention, antifreeze, anti-aging, sound absorption, integrated beautification of appearance, low installation and use costs, shorten the construction period, and solve the problem of one-time paving. all questions. Glass pumice wall tiles that do not pollute the environment duri...
