Self-repairing type heat insulation wallboard with crack reminding function

Abstract

The invention discloses a self-repairing type heat insulation wallboard with a crack reminding function, and belongs to the technical field of heat insulation wallboards. The self-repairing type heat insulation wallboard with the crack reminding function comprises a wall body, a liquid storage cavity is formed in the wall body, a plurality of evenly-distributed conveying pipes are inserted into the wall body, and the conveying pipes penetrate through the liquid storage cavity; supporting partition plates are fixedly connected to the parts, in front of the interior of the liquid storage cavity, of the conveying pipes, and outer wall cracks of the wall body can be self-repaired; foaming agents are sprayed out of the wall according to the principle that the foaming agents expand when encountering air, and the outer wall cracks are rapidly filled; and meanwhile, the inner wall corresponding to the outer wall cracks generates a series of changes, people can be reminded of the condition of the outer wall, people can conveniently observe and maintain the specific position of the cracks, people can further trim the outer wall cracks more timely, the maintenance cost is effectively reduced, and the service life of the outer wall is remarkably prolonged.

Description

technical field [0001] The invention relates to the technical field of heat-insulating wallboards, and more specifically relates to a self-repairing heat-insulating wallboard with a crack reminder function. Background technique [0002] High-performance heat-insulating materials refer to materials that are more heat-insulating than still air under working conditions. There are two kinds of materials in the world today, the first is inorganic airgel, and the other is nano-microporous heat-insulating materials. Airgel is used within 800°C, and ceramic fiber products and nano-microporous thermal insulation materials are mainly used for heat insulation in working conditions above 800°C. The nano-microporous insulation board was first developed in Germany. It is formed by pressing and molding inorganic nano-scale refractory powder through a special process to form tiny nano-scale pores, and its thermal conductivity is even smaller than that of still air. At high temperature, the...

Problems solved by technology

[0004] However, during the use of the wall, due to the long-term thermal expansion and contraction caused by temperature changes, cracks will appear on the wall. Once the crack is not noticed for a long time, it will not only affect its waterproof performance, but also make the gap between the cracks Larger, reduces its thermal insulation performance, and seriously shortens its service life, and also increases the maintenance cost in the later period
