[0045] Visually observe whether the coating film has pinholes, sags, flatness, and color blooming. If there is no phenomenon, it is considered "normal"; contrast ratio: on a colorless and transparent polyester film (thickness 40 μm), or on a Apply the tested paint evenly on black and white boards with half and half colors, and place it for at least 24hrs, and use a reflectance meter to measure the reflectance of the coating film on the black and white bottom surface; water resistance: use a mixture of paraffin wax and rosin (mass ratio 1:1) After immersing in the third grade water specified in GB / T6682 behind the edge sealing, if two of the three boards do not show blistering, powder dropping, obvious discoloration, etc., it can be rated as "no abnormality"; alkali resistance: take Three test panels, sealed with paraffin and rosin mixture (mass ratio 1:1), sealed at the back, immersed in 0.12% Ca(OH)2 saturated solution at 23±2°C, two of them did not appear within the specified...

Embodiment 3

[0047] Visually observe whether the coating film has pinholes, sags, flatness, and color blooming. If there is no phenomenon, it is considered "normal"; contrast ratio: on a colorless and transparent polyester film (thickness 50 μm), or on Apply the tested paint evenly on black and white boards with half and half colors, and place it for at least 24hrs, and use a reflectance meter to measure the reflectance of the coating film on the black and white bottom surface; water resistance: use a mixture of paraffin wax and rosin (mass ratio 1:1) After immersing in the third-grade water specified in GB / T6682 behind the edge sealing, if two of the three boards do not show blistering, powder dropping, or obvious discoloration, it can be rated as "no abnormality"; alkali resistance: take For three test panels, use a mixture of paraffin wax and rosin (mass ratio 1:1) to seal the edges and seal the back. At 23±2°C, immerse in a 0.12% Ca(OH)2 saturated solution, and two of them do not appear...

Abstract

The invention relates to a performance testing method of a water sensitive humidity-controlling coating. The method comprises the following steps: sampling a coating according to the GB3186 method, according to the requirements of GB9152-88 construction paint/coating test plate preparation, painting the coating on an asbestos cement plate, making the coated surface be upward, horizontally placing the test plate on an experiment table, allowing the test plate to stand still for 7d under adjusted states, humidity, and temperature, which are defined in GB9278-88, and finally testing. The provided method is simple, the cost is low, the measuring is rapid and precise, the measurement period is short, and the efficiency of tests on the performance of water sensitive humidity-controlling coating is effectively improved.

Description

technical field [0001] The invention relates to a test method, in particular to a performance test method of a water-sensitive humidity-adjusting paint. Background technique [0002] With the improvement of living standards, people have a certain understanding of the importance of indoor thermal and humid environment, so indoor thermal and humid environment has become a research hotspot. Researchers at home and abroad have conducted on-site investigations and studies on the indoor thermal environment of office buildings, sports buildings, teaching buildings and residential buildings. These studies are helpful for understanding the current situation of indoor heat and humidity environment in different regions, predicting occupants’ heat and humidity sensation and satisfaction, formulating feasible housing quality evaluation standards and methods, adjusting building performance, improving the form and operation mode of heating system, etc. played a very important role.
