Abstract

The invention relates to an anti-shrinkage bonding mortar for foam glass-ceramic thermal insulation material, and belongs to the field of building materials. The anti-shrinkage bonding mortar comprises a base material and an anti-shrinkage modifier, wherein the base material comprises glass-ceramic particles, sand materials and cement, and the anti-shrinkage modifier comprises dispersible latex powders, wood fibers, cellulose ether, polypropylene fiber and starch ether. According to the present invention, the glass phase inside the glass-ceramic particles has internal activity and can react with other substances under the action of the water base, such that the uniformity and the stability of the mortar during the mixing bonding are enhanced; and the crystal phase inside the glass-ceramicparticles can effectively enhance the hardness and the bonding strength of the mortar, and further make the mortar have the thermal expansion coefficient similar to the thermal expansion coefficient of the foam glass-ceramic.

Description

technical field [0001] The invention relates to an anti-shrinkage bonding mortar suitable for foam 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 such as foam ceramics, foam glass, foam glass-ceramics etc. with higher fire ratings also appear in civil buildings thereupon. [0003] However, in the existing thermal insulat...
