Abstract

The invention relates to white foam glass. The glass comprises essential components and at least one decoloring component, wherein the essential components comprise about 70-76 mol% of SiO2, about 5-9 mol% of CaO, 18 mol% to about 22 mol% of Al2O3, and about 1-2 mol% of SnCl2, and the at least one decoloring component comprises (a) NiO which is greater than 0 mol% to about 5 mol%, and / or (b) Se which is greater than 0 mol% to about 4 mol%. The white foam glass has the characteristics of being high-whiteness in appearance, low in building cost, long in service life, good in effects of heat insulation and sound insulation, light in bulk unit weight and the like, and the density is 165 kg / m<3> or below.

Description

technical field [0001] The invention relates to a new type of building material, especially a kind of white foam glass. Background technique [0002] New building materials and wall insulation systems put forward higher requirements, requiring not only good thermal insulation performance, but also outstanding compression, tensile, and aging resistance; not only reliable protection performance, but also fundamentally To block fire hazards, it must also have the characteristics of waterproof, impermeable, and permanent service life; it must be green and environmentally friendly, and it must be non-toxic and harmless; it must avoid the problems of traditional external wall insulation systems that have complicated procedures, cannot be monitored, and have no guarantee of quality. But also the process is simple, convenient for construction, and the quality is guaranteed. Existing foam insulation boards on the market are foam insulation boards made of organic polymer materials su...
