Problems solved by technology
[0005] But the above technique is an unsteady test method
The error is as large as 50% affected by the weather, and the test time is long
Expensive, inapplicable, and only suitable for heat conduction materials, not suitable for thermal resistance testing of radiation insulation materials, and there is no testing equipment and method for testing the energy-saving function of coatings in other prior art
In this way, fake coatings and inferior coatings are also approved for use, which has caused huge losses to the country and users, making it impossible for the thermal insulation coatings, which are truly excellent global advanced high-tech environmental protection materials, to be quickly tested and effectively promoted.

Embodiment
[0028] Such as figure 1 , 2 As shown, the invention provides a detection device for equivalent thermal resistance and thermal conductivity of thermal insulation coatings for buildings. The detection device includes a heat source 7 and an incubator 1, the heat source communicates with the heating chamber and provides stable heat energy for the heating chamber. Wherein heat source 7 adopted is a boiling water constant temperature boiler. Then install a support frame 103 in the incubator 1, the support frame 103 is close to the inner wall of the incubator 1, and its height is less than the interior space height of the incubator 1. Then, on the support frame 103, a partition 2 (i.e. the bottom plate described herein) made of a plastic plate is installed, so that the partition 2 divides the incubator 1 into two mutually independent spaces, which are respectively a test chamber 101 and a heating chamber. 102. Then the heating chamber 102 communicates with the boiling water const...

Abstract
The invention discloses an equivalent thermal resistance and thermal conductivity coefficient detecting device for a thermal insulation coating for a building. The device comprises a heat source and an incubator, the incubator is internally provided with a partition plate, and the partition plate divides the incubator into two test chambers and heating chambers which are independent from each other; the heat source is communicated to the heating chambers for providing stable heat energy for the heating chambers, the test chambers are internally provided with mounting frames, the mounting frames have two or more layers of mounting brackets, the mounting brackets are provided with data acquisition temperature heat flow density devices, and the top of an incubator body of the incubator is divided into a paint plate to be tested and a comparative paint plate. The device can quantitatively design the equivalent thermal resistance of the blocking radiant heat for the thermal insulation coating for the building, and according to the equivalent thermal resistance, each use unit and each detecting mechanism can distinguish the authenticity and the advantages and disadvantages of the thermalinsulation coating. The global demand for such detecting device is generated as soon as possible, the application market prospect is very good, and the promotion value is excellent.
