Problems solved by technology

[0005] The problem with the foam glass produced by the existing process is that the content of ordinary glass in the existing foam glass is too high, because the SiO in the ordinary glass 2 The content of the impurity components is relatively small, and the content of the rest of the impurities is relatively large, and the overall performance of the finished product is affected by the excessive impurities.

Abstract

The invention provides low-density building foaming glass and a preparation method thereof. The method comprises the following steps: mixing micron glass powder with a proper amount of hollow glass microspheres; directly sintering the acquired mixed particles under high temperature; and by taking the hollow glass microspheres as framework materials, splicing the microspheres after melting the micron glass powder due to the easiness in sintering of the microspheres, thereby acquiring the low-density building foaming glass. The preparation method overcomes the technical defects of relative high impurity content and influence of the excessive impurities on the overall performance of the prepared end product of the foaming glass preparation in the prior art; the mixture prepared according to the invention is directly sintered under high temperature; except for the glass raw material, the mixture almost contains no other impurity; the joint parts of the accumulated glass microspheres are formed into glass microspheres with porous structure and uniform size; the generated pores are uniformly distributed, the pore size distribution is narrower and the product is high in strength; and the low-density building foaming glass is suitable for high-strength building materials and decorative materials.

Description

technical field [0001] The invention relates to the field of material processing, in particular to a low-density building foam glass and a preparation method thereof. Background technique [0002] Foam glass is composed of quantitative cullet, foaming agent, modifying additives and accelerators, etc., which are finely pulverized and mixed uniformly to form a batch, which is put into a specific mold, and then preheated, melted, foamed, etc. Porous glass materials made by foaming, annealing and other processes. Foam glass is composed of a large number of uniform bubble structures with a diameter of 0.1-3mm, and the bubbles account for 80%-95% of the total volume. Its apparent density is 120-500kg / m 3 , according to the requirements of use, its density can be adjusted by changing the production technical parameters. [0003] Foam glass is a light-weight and high-strength building material and decorative material with superior performance in heat insulation, sound absorption,...
