Abstract

The invention relates to an external wall insulation structure through a foaming cement board and a construction method of the external wall insulation structure through the foaming cement board. Polymer bonding mortar, a foaming cement board, an anti-cracking layer and a decorating layer are arranged in sequence from the surface of a base wall body, the anti-cracking layer is formed by light plastering mortar and glass fiber gridding cloth, and the external wall insulation structure is characterized in that the light plastering mortar consists of the following components by weight percent: 12-25% of polyacrylic emulsion, 0.15-0.24% of cellulose ether, 0.1-0.5% of polypropylene fiber, 0.1-0.2% of dispersing agent, 0.1-0.2% of mildew preventive, 15-25% of ordinary portland cement, 15-30% of glazed hollow bead, 5-20% of quartz sand, 0-30% of coal ash and 0.5-1% of water reducing agent.

Description

technical field [0001] The invention relates to a thermal insulation structure of a foamed cement board outer wall and a construction method thereof. Background technique [0002] As the country pays more attention to the fire performance of building exterior insulation materials, the foam cement board exterior insulation system is favored by the majority of users. It has the advantages of excellent fire performance, easy access to insulation raw materials, and the same life as the building. The promotion time is late, and there are also disadvantages such as few materials and construction specifications, lack of operating experience of construction personnel, poor matching of materials, and large self-weight, which lead to cracking and abnormal water seepage in the system, which affects the promotion work. At present, the common external insulation structure of foamed cement board external walls in the market is: base wall + bonding mortar layer + foamed cement insulation b...
