Abstract

The invention discloses microporous foam glass and a preparation method thereof, and relates to the field of glass products. The foam glass is prepared from the following raw materials of crushed glass powder, mordenite zeolite, hyalophane mica, modified quartz powder, kaolin, titanium dioxide, sodium fluoride, reinforced fiber, adhesive, foaming agent and foam stabilizer. The preparation method comprises the following steps: smashing raw materials, melting, cooling, standing, foaming, annealing, foaming and polish. The production raw materials of the foam glass are wide in source, and are simple in a preparation process; the finished product of foam glass contains a large amount uniform, unique and enclosed micropores inside, so that the heat-insulation high temperature and compressive resistance of the foam glass product are improved remarkably, as well as long service life, wide application field and suitability for popularization and application are achieved.

Description

technical field [0001] The invention relates to the field of glass products, in particular to a microporous foam glass and a preparation method thereof. Background technique [0002] Foam glass is a kind of inorganic non-metallic material containing a large number of uniform bubbles, which is made of crushed glass powder, foaming agent and additives, etc. glass material. The physical and chemical properties of inorganic glass and its internal bubbles determine the density, thermal conductivity and mechanical strength of this material; many foam glasses on the market have problems such as uneven distribution of internal bubbles, different sizes of bubbles, and poor consistency. , the overall physical and chemical properties of foam glass are greatly limited and affected, especially the heat insulation and high temperature resistance and compressive strength, which seriously affect the use function and life of foam glass products. Therefore, it needs to be improved. Content...
