Abstract

The invention provides a building coating odor evaluation method and application, and relates to the technical field of coating odor determination. The building coating odor evaluation method comprises the following steps that: a sealed odor room is provided, a building coating is coated on the wall of the odor room, an exhaust fan in the odor room is turned on, the gas in the odor room is conveyed to a gas storage device outside the odor room through using a gas conveying pipe connected with the exhaust fan, and the gas evaluator evaluates the odor of the building coating by smelling the gasin the gas storage device. The building coating odor evaluation method provided by the invention is more suitable for the actual use condition of the building coating, can avoid seamless mixing of thecoating odor and the air, enables the evaluation result to be more accurate, can better reflect the odor of the building coating, provides a unified detection method for evaluating the odor of the building coating, and has a wide application prospect in the field of detection of the odor performance of the building coating.

Description

technical field [0001] The invention relates to the technical field of coating odor measurement, in particular to a method and application for evaluating the odor of architectural coatings. Background technique [0002] In recent years, with the rapid development of the world economy and the improvement of people's living standards, more and more attention has been paid to protecting the environment and saving resources. The development direction and industrial structure of the world's coatings have undergone tremendous changes, causing the modern coatings industry to rapidly move towards functional Therefore, the improvement and development of coating performance is essential, and the accompanying testing methods for coating performance are gradually improving. [0003] As one of the important indicators of paint performance, odor can most intuitively show one of the key points of customers' evaluation of paint quality. At present, the smell of different paint products is d...
