A building top insulation board with self-sealing function

Abstract

The invention discloses a building top thermal insulation board with the function of self-repairing joints, which belongs to the technical field of building thermal insulation materials and can be equipped with a special radiation-reducing outer layer, a solid-reducing middle layer, an air-reducing inner layer, and a radiation-reducing outer layer. The outer layer, solid-reduction middle layer, and air-reduction inner layer can respectively reduce the heat conduction caused by radiation, solid phase, and gas phase, thereby significantly improving the thermal insulation performance of the insulation board, and by repairing the setting of the seam bead, it will make the heat transfer when the radiation is reduced When cracks appear on the upper surface of the outer layer, the sealing block can spontaneously decompose and fall off, and trigger the upward movement of the seam filling storage column, so that the ball-pricking steel needle punctures the sealing balloon, and through the mixing of fillers, elastic airbags, etc. The ingenious setting makes the seam repairing material storage column rise continuously, thereby driving the top plate of the pressure bag to squeeze the elastic air bag, and then extruding the thermal insulation seam sealant to repair the cracks until the crack repair is completed, so that the seam repair beads can automatically reduce radiation. Repair the cracks on the upper surface of the outer layer.

Description

technical field [0001] The invention relates to the technical field of building thermal insulation materials, and more specifically relates to a building top thermal insulation board with the function of self-sealing. Background technique [0002] Building insulation materials are used to reduce the indoor heat of the building to the outside by taking measures on the building's outer envelope, thereby maintaining the building's indoor temperature. Building insulation materials play an important role in creating a suitable indoor thermal environment and saving energy in building insulation. [0003] The building top insulation board is the insulation material installed on the top of the building. Most of the building top insulation boards in the prior art are made of foam insulation materials. The effect is limited, and the top insulation board is located at the top of the building. Its upper surface is exposed to sunlight and rain for a long time, which is prone to cracks. ...

[0003] The building top insulation board is the insulation material installed on the top of the building. Most of the building top insulation boards in the prior art are made of foam insulation materials. The effect is limited, and the top insulation board is located at the top of the building. Its upper surface is exposed to sunlight and rain for a long time, which is prone to cracks. However, the existing top insulation board of the building cannot automatically repair the cracks, which will greatly reduce the insulation effect , poor practicality
