摘要
以双端丙烯酰胺基丙基聚硅氧烷（diAAp-PDMS）为交联剂,通过细乳液聚合法改性聚丙烯酸酯,并将其用于涂料印花。研究了交联剂diAAp-PDMS用量对改性乳液性能、胶膜结构与性能和印花性能的影响。结果表明：随着diAAp-PDMS用量的增加,聚合单体转化率降低,凝胶率增大,乳液粒径变大;胶膜交联度先增后减,胶膜聚硅氧烷表面富集增加,胶膜耐水性先增后降,胶膜断裂强度降低,断裂延伸率增加,断裂功先增后减;印花织物耐干、湿摩擦色牢度先增后降,柔软性提高。当diAAp-PDMS用量为8%时,胶膜交联度最高,疏水性最强,断裂功最大,印花织物耐干、湿摩擦色牢度可达4～5级,手感柔软。
A silicone-modified polyacrylate miniemulsion was prepared by silicone crosslinking agent double terminated acrylamide-propyl polysiloxane（diAAp-PDMS） and acrylate monomers.The modified miniemulsion was used for pigment printing.The influences of dosage of crosslinking agent diAAp-PDMS on properties of the modified miniemulsion,modified polyacrylate film and pigment printing were studied.The results showed that with the increase of the dosage of diAAp-PDMS,the monomer conversion of miniemulsion polymerization became lower,and the agglomerate rate and the particle size of miniemulsion be came bigger.The degree of crosslinking of the modified film increased at first and decreased at last,the rich amount of PDMS on the surface of the film increased,the hydrophobicity of the film increased at first and decreased at last,the breaking tenacity of the film became lower,the breaking elongation rate of the film increased,and the work of break increased at first and decreased at last.The colour fastness to dry and wet rubbing of the pigment printed fabric increased at first and decreased at last,and the softness of the printed fabric improved.When the dosage of diAAp-PDMS was 8%,the degree of crosslinking of the film was the highest,the hydrophobicity of the film was the strongest,the work of break was the biggest,and the colour fastness to dry and wet rubbing of the pigment printed fabric could reach 4-5degree,and the handle of the printed fabric was soft.
