不同基团对丙烯酸酯乳液涂饰剂性能影响的研究

Effect of Different Groups on Property of Acrylic Hybrid Emulsion

介绍了通过乳液共聚分别把—CN ,—COOH ,—CONH2 ,—C6H5,—OH等基团引入丙烯酸酯大分子链中 ,研究这些基团分别对丙烯酸酯乳液涂饰性能的影响。实验结果表明 :这些极性基团的引入使涂饰剂性能有不同程度的提高 ,其中以—CONH2 提高幅度最大 ,其次为—COOH ,—OH。提高幅度最小的是—C6H5和—CN。

The influences of the different groups, such as -CN, -COOH, -CONH 2, -C 6H 5, -OH, etc, on the properties of acrylic hybrid emulsion are discussed in this paper. The film properties of hybrid emulsion, eg. resistances to water and solvent, tensile strength and elongation are improved.
