Description

Technical Field

[0001] The present invention belongs to the technical field of water-based paint quality detection, and in particular relates to a method and system for analyzing the weather resistance of water-based paint under multiple environmental conditions. Background Art

[0002] Water-based paint uses water-based polymers as film-forming substances, which reduces VOC emissions and has many advantages such as safety and no fire hazards. With the continuous improvement of the public's environmental awareness in recent years, water-based paint has developed rapidly, resulting in an increasing number of water-based paint applications in new scenarios. However, different new scenarios mean that the environmental conditions they face are changeable and complex, and the weather resistance performance evaluation of water-based paint is an important indicator for determining the quality of water-based paint.

[0003] At present, there are usually two methods for testing water-based paints. One is to conduct weathering resistance testing on water-based paints produced with different formulas before mass production, and the other is to strictly control the production process, finished product testing and other links in the water-based paint production process during mass production to ensure that the quality of the final product meets the standards. However, in the prior art, due to the increasing number of water-based paints used in new scenarios, the weathering characteristics of water-based paints that need to be tested are varied and complex, and the test data obtained by different testing methods are different, resulting in a variety of testing methods for water-based paints before mass production. There is no unified and standardized testing process, and corresponding testing personnel are required to see the performance of water-based paints based on the test data. This is very unfavorable to the quality management of water-based paints within the paint production company, and greatly affects the difficulty of comprehensive quality control of water-based paints.
