Housing construction coating layer structure with heat insulation and preservation functions

Abstract

The invention provides a housing construction coating layer structure with heat insulation and preservation functions. The side, away from a first sawtooth protrusion, of a first elastic connecting layer is bonded to a first fixing plate; a vacuum heat insulation layer comprises a first heat insulation frame and a second heat insulation frame; an inner side secondary vacuum cavity is defined between the first heat insulation frame and the first fixing plate; an outer side secondary vacuum cavity is defined between the second heat insulation frame and a second fixing plate; and a sealed main vacuum cavity is defined among the first heat insulation frame, the second heat insulation frame, a first low-radiation glass plate and a second low-radiation glass plate. According to the housing construction coating layer structure with the heat insulation and preservation functions, an outer elastic heat preservation layer, the vacuum heat insulation layer and an inner elastic heat preservation layer are arranged in the housing construction coating layer structure, the outer side secondary vacuum cavity, the main vacuum cavity and the inner side secondary vacuum cavity are formed, and heat conduction on the two sides of the device is effectively isolated; and the device has an elastic buffering function, and the problem that a coating layer is damaged due to heat expansion and cold contraction is effectively avoided.

Problems solved by technology

[0003] However, there are still relatively obvious defects in its use: 1. The above-mentioned device realizes heat insulation and heat preservation through simple assembly between paint layers, and its effect is very limited, and it cannot play an effective heat blocking effect ; 2. All the coating layers of the above-mentioned device are fixedly connected, which will expand or shrink due to water absorption, frost heave, cold and heat cycle, etc., which will cause deformation of the coating layer, expansion and separation between the coating layers, or mutual extrusion etc., resulting in a reduction in the service life of the device and the need for frequent replacement, which consumes manpower and increases the cost of use
