Data analysis
The VOC content in comparative example 1 is higher than that in examples 1, 2 and 3, and the gloss, water resistance, hot water resistance and corrosion resistance at 20 ℃ are lower than those in examples 1, 2 and 3, because the content of methallyl chloride is not reduced and the VOC content is increased without substantially improving various properties of the product in comparative example 1 without adding anhydrous sodium sulfate.
The VOC content in the comparative example 2 is higher than that in the examples 1, 2 and 3, and the gloss, water resistance, hot water resistance and corrosion resistance at 20 ℃ are lower than those in the examples 1, 2 and 3, because the glossiness is reduced without adding N-tertiary butyl acrylamide in the comparative example 2, the content of methallyl chloride is kept unchanged, the VOC content is increased, and the performance of all aspects of the product is not substantially improved.
The VOC content in comparative example 3 was low with respect to example 1, example 2, and example 3, and the VOC content in comparative example 4 was high with respect to example 1, example 2, and example 3, and the gloss, water and hot water resistance and corrosion resistance at 20 c in comparative example 3 and comparative example 4 were low with respect to example 1, example 2, and example 3, because no methallyl chloride was added in comparative example 3, no 2-aminophenol-4-sulfonanilide was added in comparative example 4, and no methallyl chloride was used in comparative example 3, ensuring that the VOC content was not changed but the gloss and chemical resistance were reduced, no coupling occurred in comparative example 4, the gloss of the product was not improved, and the water resistance and high temperature resistance of the product were not substantially changed.
