Abstract
The invention relates to a heat preservation system, and particularly relates to an inorganic fireproof building heat preservation system and a construction method thereof. The system comprises a wall body, wherein a bonding mortar layer, a heat preservation board, a surface covering layer and a surface decorating layer are arranged on the outer surface of the wall body in sequence; and the surface covering layer comprises an anchoring part, a first surface covering anti-crack mortar layer, an alkali-resisting coating screen cloth layer and a second surface covering anti-crack mortar layer. The construction method comprises the following steps: pre-processing the wall body, mixing and stirring the bonding mortar with water, daubing the mixture on the outer surface of the wall body, sticking the heat preservation board on the bonding mortar layer, penetrating the anchoring part through the heat preservation board to be fixed on the wall body, then mixing and stirring the surface covering anti-crack mortar with water, uniformly daubing the mixture on the surface layer of the heat preservation board, paving the alkali-resisting coating screen cloth, daubing the mixed and stirred surface covering anti-crack mortar again after the surface covering anti-crack mortar layer is solidified, and uniformly daubing architectural paint or sticking furring bricks on the outer surface of the surface covering to form the surface decorating layer. The heat preservation system is low in heat conductivity coefficient, sound in heat preservation effect, high in compressive strength, good in durability and low in cost, saves the energy, and protects the environment.
Description
technical field [0001] The invention relates to a thermal insulation system, in particular to an inorganic fireproof building thermal insulation system and a construction method thereof. Background technique [0002] In the cold winter, especially in northern China, the winter is very cold. In order to make the temperature inside the room in winter meet the requirements of use and the needs of building energy conservation, the most practical and economical method is to install the outer wall, inner wall and The roof is provided with an insulation layer. [0003] At present, the external wall thermal insulation system in the construction industry market mostly adopts the method of polystyrene board external wall thermal insulation board or foamed cement board plus mortar coating. The full name of polystyrene board is polystyrene foam board, also known as foam board or EPS board. The white solid with porous structure, although the board has low density, light weight, and sma...
