Abstract

The invention discloses a glazed hollow bead polymer mortar and polyurethane composited external thermal insulation system. The external thermal insulation system comprises a base wall and rigid foamed polyurethane bonded to one side of the base wall, wherein interface treating mortar is bonded to one side of the rigid foamed polyurethane; glazed hollow bead thermal mortar is bonded to one side of the interface treating mortar; anti-crack mortar is bonded to one side of the glazed hollow bead thermal mortar; flexible waterproof putty is bonded to one side of the anti-crack mortar; and a coating finish coat is bonded to one side of the flexible waterproof putty. The rigid foamed polyurethane and the glazed hollow bead thermal mortar can be well combined through the interface treating mortar, and further, the glazed hollow bead thermal mortar is fast and convenient to construct and good in integral formability; the structure is simple and reasonable, field spray coating construction is simple and fast, a mixture having liquidity and permeability can enter base void for foaming and is firmly bonded with the base, additional anchoring and the like are not required, an insulating layer is seamless, the integrity is good, and the application range is wide.

Description

Technical field [0001] The present invention involves a vitric micro bead polymer mortar composite polyurethane external wall insulation system, which belongs to the field of civil construction. Background technique [0002] Overseas wall insulation is an important part of energy -saving buildings.In recent years, the construction standards and requirements of building energy -saving design have gradually improved. At the same time, with the development of people's aesthetic views and building personalization, the effect of the facade of the building has gradually developed to diversified, and the complicated projects of the building facade have continued to emerge.The buildings with many changes in the building facade have many connectors during thermal insulation construction, the construction process is complicated, and the phenomenon of cracking and leakage of the insulation system is prone to occur.Therefore, it is particularly important to meet the emergence of new insulati...
