Abstract

The invention belongs to the technical field of novel building materials, and particularly relates to an adhesive mortar for external wall heat insulation which includes, by mass, 25-35 parts of ordinary Portland cement, 30-60 parts of a sand substance, 10-30 parts of fly ash, 1.2-5 parts of redispersible latex powder, 0.2-0.3 parts of polyvinyl alcohol, 0.1-0.15 parts of polyacrylamide, 5-6 parts of heavy calcium, 0.1-0.4 parts of hydroxypropyl methyl cellulose ether, and 0.1-0.4 parts of modified polyoxyethylene. The adhesive mortar is improved in adhesion force, water resistance heat insulation, constructability, flexibility, wear resistance, flocculability and toughness.

Description

technical field [0001] The invention belongs to the technical field of new building materials, and in particular relates to an adhesive mortar for external wall heat preservation. Background technique [0002] Adhesive mortar is mainly used as an adhesive for bonding insulation boards, also known as polymer insulation board adhesive mortar. Since the external wall thermal insulation system has been paid more and more attention by people, the bonding mortar, which is one of the important parts of the external wall thermal insulation system, is also constantly being developed and developed. However, the bonding mortar in the prior art still has bonding Strength, tensile strength, anti-aging, freeze-thaw resistance, water resistance and other defects with poor performance. Contents of the invention [0003] Aiming at the deficiencies of the prior art, the present invention provides an adhesive mortar for thermal insulation of external walls with improved adhesive force, wate...
