Abstract

The invention relates to an anti-shrinkage bonding mortar suitable for foamed glass-ceramic thermal insulation materials, which belongs to the field of building materials. The anti-shrinkage bonding mortar suitable for foamed glass-ceramic thermal insulation materials of the present invention includes a base material and an anti-shrinkage modifier; the base material includes glass-ceramic particles, sand substances and cement; the anti-shrinkage modification Agents include dispersible latex powder, wood fiber, cellulose ether, polypropylene fiber and starch ether. The glass phase inside the glass-ceramic particles is internally active, and can react with other substances under the action of the water base, which enhances the uniformity and stability of the mortar during the mixing and bonding process; the crystal phase inside the glass-ceramic particles can Effectively enhance the hardness and bonding strength of the mortar, and at the same time, the glass-ceramic particles also make the mortar have a thermal expansion coefficient similar to that of the foamed glass-ceramic.

Description

technical field [0001] The invention relates to an anti-shrinkage bonding mortar suitable for foamed glass-ceramic thermal insulation materials, which belongs to the field of building materials. Background technique [0002] Polyurethane (PU), molded polystyrene foam (EPS), extruded polystyrene foam (XPS) and other organic insulation materials used to be the mainstream of exterior wall insulation materials, but with the wide application of organic insulation materials, At the same time, it also exposed the problem of insufficient fire resistance. Most organic insulation materials will produce more smoke and toxic gases during incomplete combustion or pyrolysis, and most people in fire accidents are suffocated to death by inhaling smoke and toxic gases. Therefore, inorganic thermal insulation materials with higher fire ratings, such as foam ceramics, foam glass, and foam glass-ceramics, have also appeared in civil buildings. [0003] However, in the existing insulation syst...
