The detection of effect in practice.
Background technique
As country advocates the implementation of energy-saving and environmental protection industrial policy, especially building energy conservation, involve a wide range of knowledge, even more increasingly
It is taken seriously.The appearance of GB/T 25261-2018 " reflective heat-insulation paint for building " new national standard, these all strong promotions are anti-
Penetrate the development of insulating moulding coating.At present for the performance detection of reflective heat-insulation paint (sun luminous reflectance, near-infrared reflection ratio and half
Ball emissivity) still use aluminium sheet to be detected as test ground, because near infrared ray is also that straight line is worn as visible light
It broadcasts, and there is also the basic laws of reflection, absorption, transmission.Such test cannot characterize the property of reflective heat-insulation paint completely
Can, because coating obtains the close of coating there is phenomenon, the high reflectance that can use testing substrates aluminium sheet is transmitted in near-infrared
The higher phenomenon of infrared external reflection ratio.So as to cause detection data and the difference actually between wall effect, it is unfavorable for so anti-
Penetrate the overall development of insulating moulding coating.

53%, therefore covering power to near-infrared or albedo directly reflect the heat-proof quality of coating.The present invention effectively solves
Calculating to the covering power of near infrared ray, accurately can objectively reflect the reflective insulation performance of coating, and avoid experiment
Difference problem between room detection data and actually wall effect.
Summary of the invention
The purpose of the present invention is to solve detection data existing for existing building reflective heat-insulation paint and actually wall imitate
The problem of being had differences between fruit, and a kind of detection method of architectural reflective heat-insulation paint (flat to apply) heat-proof quality proposed.
To achieve the goals above, the following technical solution that the present invention takes:
Step (1) tests the reflectivity of black and white paper jam using Albedometer;
Step (2) carries out multiple tracks film using bar spreader on black and white paper jam;
After the completion of step (3) film, test plate (panel) is put under normal environment conditions and carries out maintenance 7 days;
Step (4) is close red on paper jam blank and blackboard using ultraviolet-visible-near infrared spectrometer testing coating
External reflectance ratio;
Calculation formula of the step (5) according to covering power, is calculated coating in the covering power of near-infrared part.
Further, III Albedometer of C84- used in step (1) tests the blank and blackboard of black and white paper jam
Reflectivity after testing 4 points respectively on blank and blackboard, calculates its reflectivity average value.
Ensure the reflectivity for the substrate tested in blackboard reflectivity < 1%, blank reflectivity through the above technical solution
(80 ± 2) %, so that it is guaranteed that test result is more accurate.
Further, RDS bar spreader is used in step (2), and the consistent paint film of uniform thickness is made.
By using above-mentioned technical proposal, coating thickness can be effectively controlled using RDS spreader.The coating of different size
The uniform coating of different-thickness can be made in device, to reach the test request of 150 microns of final thickness of dry film or more.
Further, the good film of film is conserved, film is placed by according to the requirement of test in step (3)
It is conserved under constant-temperature constant-humidity environment, curing time is 7 days.
By using above-mentioned technical proposal, film obtained is unstable in room temperature, needs to transfer in constant temperature and humidity condition
It just can ensure that the optimal test mode of film after setting maintenance 7 days.
Further, step (4) uses but is not limited to 5000 ultraviolet-visibles of Agilent Cary-near-infrared spectrophotometric
Meter, test wavelength range 175-3300nm, measurement accuracy 0.1nm.
By using above-mentioned technical proposal, the wave-length coverage of spectrophotometer is greater than test request (300-2500nm) wavelength
Accuracy≤± 0.4nm, wavelength repeatability near-infrared≤± 0.02nm, can computer be automatically brought into operation, it is easy to use, it is intelligent
Degree is high, carries out testing 3 points on each test surfaces when near-infrared reflection ratio test, its average value is taken, to guarantee test
Accuracy.
Further, near-infrared reflection ratio of the step (5) according to test, can be calculated using the calculation formula of contrast ratio
Covering power of the coating in near-infrared.
The utility model has the advantages that being tested with aluminium sheet is used as substrate, it is an advantage of the invention that can be more accurate objectively anti-
Heat insulation after mirroring architectural reflective heat-insulation paint actually wall, Comparison between detecting methods are simple and are all to utilize existing detection
Instrument.
