Description
Technical Field
The invention relates to a method for testing the reflective insulation durability of a reflective insulation texture coating, and belongs to the technical field of coating quality detection.
Background
The reflective heat-insulation texture coating not only has the stereoscopic impression and color of the common texture coating, but also can reflect sunlight, reduce the temperature rise of the outer wall of a building caused by sunlight absorption, and achieve the purpose of reducing the energy consumption of an air conditioner. The reflective heat insulation texture coating adopts white sand, infrared reflective titanium dioxide and cold color paste (or compound color paste) for modeling and color mixing, and has unique stereoscopic impression, rough surface and bright color. However, the rough surface is easy to stain, and the bright color formed by color paste toning is easy to fade, so that the reflective insulation effect of the reflective insulation texture coating is gradually reduced, and the test of the durability of the reflective insulation is very important.
When the reflective heat insulation texture coating is constructed, a construction manual generally requires that a putty layer is scraped and then cured (1-2 times of rinsing with clear water) to reduce the surface alkalinity, so that the next procedure can be carried out, but the putty base material alkalinity is very strong due to the fact that the putty base material alkalinity is not maintained for the purpose of reaching the construction period in many times, and local primer coating leakage can occur frequently during large-area construction, so that local saltpetering can be caused, the reflective heat insulation texture coating is toned with color paste, organic resin and the color paste in the coating can be damaged by alkaline substances, so that local whitening, fading and degradation pulverization are caused, and the reflective heat insulation effect is finally influenced. In addition, the water absorption rate of the base material in the primer coating leakage area is high, slurry and water in the reflective insulation texture coating seep too fast, a very rough surface (strong sand feeling and dull luster) can be formed, color difference can be caused, dust and stain are more easily hung, and the reflective insulation effect is reduced more quickly. Most of reflective heat insulation texture paint needs to be matched with finish varnish for use, the finish varnish also has the problem of missing coating during large-area construction, the gloss of a missing coating area is relatively dull, color difference can be generated, the stain resistance and weather resistance of the missing coating finish varnish area are poor, and the reflective heat insulation effect is reduced more quickly in the using process.
At present, the reflective insulation durability is mainly tested according to the relevant regulations of JG/T235-2014 reflective insulation coating for buildings: according to the color depth (brightness value) of the reflective insulation texture coating, the solar reflectance TSR and the near infrared reflectance NIR which meet the requirements are selected, then the fly ash is prepared, artificial accelerated aging (QUV) is carried out to simulate contamination and aging, and then the sunlight reflectance change rate before and after contamination and the sunlight reflectance change rate before and after aging are tested to represent the durability of the reflective insulation effect. However, in the using process of the reflective insulation texture coating, the actual environment is greatly different from the simulated contamination and aging environment, and the reflective insulation durability of the reflective insulation texture coating is greatly different from the data obtained according to the JG/T235-2014 test. Moreover, the staining and aging of the reflective insulation texture coating are performed simultaneously when the reflective insulation texture coating is actually used, so that the accuracy of the data obtained according to the JG/T235-2014 test is low.
