Abstract

The invention provides a method for manufacturing a structure-insulation-integrated composite insulation board. The method comprises the following steps: a. mixing and stirring the components in parts by weight to form cement mortar for later use; b. mixing and stirring the components in parts by weight to form thermal mortar for later use; c. cutting a groove in an organic board of an insulation layer according to a preset style, and filling the insulation mortar in the step b and a high-effective flame retardant in the groove; d. laying a reinforcing layer on the inner side of the organic board by using the cement mortar and gridding cloth, and maintaining for 5-9 days; e. laying the thermal mortar on the outer side of a maintained product to form a heat storage transition layer, and laying an outer-side reinforcing layer on the outer side of the heat storage transition layer; and f. maintaining the product in the step e for 26-30 days to leave a factory. The groove filled with the flame retardant and the thermal mortar is formed in the board body, so that the fireproof performance is improved. The heat storage transition layer is laid on the outer side of the insulation board, so that the adverse consequence of the environmental temperature change on the insulation board is furthest avoided.

Description

technical field [0001] The invention relates to the field of thermal insulation, in particular to a method for manufacturing a structural thermal insulation integrated composite thermal insulation board. Background technique [0002] The building insulation industry has gained a huge market under the implementation of my country's important national policy of building energy conservation. In order to meet the energy-saving standards stipulated by the state, the existing building insulation boards mostly use organic boards such as polystyrene foam board (EPS) and polystyrene extruded board (XPS). [0003] While the above-mentioned organic board has good thermal insulation performance, it also has the disadvantage of being flammable. This is undoubtedly a major safety hazard of thermal insulation buildings. According to GB8624-1997 and GB8624-2006, these organic boards are far from meeting the fire protection requirements of Class A. [0004] In view of this, the present in...
