在制备低毒、低污染、低消耗、高性能的水溶性涂料时,我们常用顺丁烯二酸酐与亚麻油加成来制备能够水溶的顺丁烯二酸酐化亚麻油(后简称;酐化油),其中酐化油中酐的含量的多少,直接影响树脂的水溶性,漆液的稳定性和漆膜性能。而目前测定酐化油中酐含 In the preparation of low toxicity, low pollution, low consumption, high performance water-soluble paint, we often use maleic anhydride and linseed oil addition to prepare water-soluble maleic anhydride linseed oil (hereinafter referred to as; Oil), in which the amount of anhydride in the anhydride content, a direct impact on the water-soluble resin, paint liquid stability and film properties. At present, the determination of anhydride anhydride anhydride content
