一种反应型染料的合成及其在聚氨酯革染色中的应用
Synthesis of a Polymerizable Dye Monomer and Its Application in Dyeing Polyurethane Leather
摘要
Abstract
In order to solve poor color fastness and serious color transfer of the traditional color polyurethane leather because of weak interaction(intermolecular force) between polyurethane and color base.A kind of reactive color diol was synthesized as follows:p-aminoacetanilide with a yield of 85% was prepared by acylation of p-phenylenediamine with acetic anhydride in tetrahydrofuran at 0~5 ℃ for 15 h, during which the molar ratio of p-phenylenediamine to acetic anhydride was 1.00∶0.95. Then its diazonium salt was coupled with an excess molar fraction of 5% N-phenyl-diethanolamine to obtain 4-acetylamino-4′-N,N-dihydroxyethylamino azobenzene with yield of 82%. The reactive color diol was mixed with polyester or polyether diol in different proportions, followed by prepolymering, chain extension with diisocyanate to form polyurethane resin color paste whose crack-growth rate, relative breaking strength, and color transfer are 443%, 125.5 g and 21.4 μg, respectively, when spreaded into a film. And those of the similar film obtained from import diol are 442.2%, 125.3 g and 29.2 μg, respectively, indicating that the synthetic color diol is superior to the imported product.关键词
