Abstract

The invention discloses an equivalent thermal resistance detection device and detection method of thermal insulating coating. Thermal couplers and solar radiation sensors are both in signal connection with a detection instrument; and the detection instrument is in signal connection with a calculating terminal. The detection method comprises the following steps of: respectively adhering thermal couplers with metal sheets to the middle parts of the outer surfaces of a plurality of outer walls by using adhesive tapes; after the adhesive tapes are thoroughly dried and solidified, coating the thermal insulating coating and common paint on the outer surfaces of the outer walls respectively; enabling the outer walls to be detected to receive the sunshine radiation, and acquiring data by using the solar radiation sensors; after the solar radiation sensors constantly acquire for seven days, selecting valid data of four days and transmitting to the calculating terminal; and reckoning out the equivalent terminal resistance of the thermal insulating coating on the detected walls with the combination of calculating software. In such a mode, data can be accurately acquired to join in the calculation with the combination of an on-site thermal engineering detection method aiming at the conditions necessary for on-site detection of the thermal insulating coating, curves of output temperature are effectively analyzed, and the equivalent thermal resistance of the thermal insulating coating is reckoned.

Description

technical field [0001] The invention relates to the field of coating detection, in particular to a detection device and detection method for equivalent thermal resistance of heat-insulating coatings. Background technique [0002] In recent years, heat insulation coatings have been developed as a functional coating with heat insulation, sun protection, energy saving, environmental protection, simple construction, short construction period and quick effect. There are three main types of thermal insulation paint from the principle of characteristics, insulating conductive thermal insulation coatings, reflective thermal insulation coatings and radiation thermal insulation coatings. In addition to the above three types of heat-insulating coatings, there has been a heat-insulating coating for heat-insulating functional coatings in foreign countries. In addition to the advantages of the above-mentioned heat-insulating coatings, it also has a unique thermal insulation effect. [00...
