In this work, modified silicone tie-paints were prepared in a simple way for securing adhesion between the epoxy anticorrosive primer and silicone fouling release coating. Hydroxy-terminated polydimethylsiloxane (PDMS) mixture containing fillers and accessory ingredient was prepared as base component. N-(2-Aminoethyl)-3-aminopropyltrimethoxysilane (DAMO) was mechanically mixed with other functional additives as curing component. ATR-FTIR, XPS, SEM and tensile tests were used to investigate the chemical structure, morphology and mechanical properties of the tie-coatings. It was focused on the effect of the DAMO content on the adhesion of the tie-coating to epoxy primer. Peel off and shear tests were carried out to evaluate the adhesion. The results showed that introducing DAMO can significantly improve the properties of the tie-coating. The adhesion between the tie-coating and the epoxy primer increases with the increase of DAMO content, but the excessive DAMO content will decrease the fracture strength of the tie-coating and decrease the quality of the coating. When the DAMO content in tie-coating is 1.97 wt.%, the tie-coating performs excellent in the interlaminar adhesion, shear strength and mechanical properties.

N-（2-氨基乙基）-3-氨基丙基三甲氧基硅烷对改性有机硅领带涂料对环氧底漆黏附的影响

在这项工作中，以一种简单的方法制备了改性的有机硅粘结漆，以确保环氧防腐底漆与有机硅结垢释放涂料之间的附着力。制备包含填料和辅助成分的羟基封端的聚二甲基硅氧烷（PDMS）混合物作为基础组分。将N-（2-氨基乙基）-3-氨基丙基三甲氧基硅烷（DAMO）与其他功能性添加剂作为固化组分进行机械混合。使用ATR-FTIR，XPS，SEM和拉伸测试来研究粘结层的化学结构，形态和力学性能。它集中于DAMO含量对粘结层与环氧底漆粘合力的影响。剥离并进行剪切测试以评估粘合性。结果表明，引入DAMO可以显着改善粘结涂层的性能。随着DAMO含量的增加，粘结层与环氧底漆之间的附着力增加，但是过量的DAMO含量会降低粘结层的断裂强度，并降低涂层质量。当粘结层中的DAMO含量为1.97重量％时，粘结层在层间粘合性，剪切强度和机械性能方面表现优异。
