Abstract

The invention relates to a method for increasing the porosity of a white foam glass in situ, wherein the glass comprises a base component and at least a coloring component, the base component comprises 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 Na2O, the coloring component comprises: a) more than 0 mol% to about 5 mol% of NiO, and / or b) more than 0 mol% to about 4 mol% of Se, and ball milling mixing, pre-forming, preheating, foaming sintering, cooling and stress relief annealing are performed to obtain the product. According to thepresent invention, the foam glass obtained by adding the additional foaming agent during the pre-forming has characteristics of high porosity, high-whiteness appearance, light weight per unit volume,low sintering temperature and low cost.

Description

technical field [0001] The invention relates to a method for preparing a novel building material, in particular to a method for increasing the porosity of white foam glass in situ. 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 ar...
